In Kerala University and many other Universities, the subject of Financial Econometrics has included under two major modules in the Course „Quantitative Techniques and Financial Econometrics‟ in the PG curriculum. As the content of the syllabus is new to Commerce teachers, a short term training course in the form of a workshop is considered essential. At the same time, there is shift in focus of data analysis towards analysis of econometric data. Researchers are using Econometric modeling techniques in cross sectional data, time series data and panel data. In practice, these models are used for many practical situations involving measuring the volatility, CAPM, simulation and the like. Thus the topic of workshop is highly relevant for Commerce and Management research nowa –days. Thus the Research and Post Graduate Department of Commerce selected Financial Econometrics as the main theme of the workshop during this plan period (2019-20). SELECTION OF CHIEF TRAINERS As we need to impart both basic and advanced level training in the subject with a direct focus on two groups of participants viz. Teachers and Research Scholars, we decided to select Dr. S. Kevin, the former Pro-Vice Chancellor of University of Kerala and Professor of Commerce to impart the foundation training and Dr. Vijayamohanan Pillai, Professor, Centre for Development Studies to impart advanced training in the selected topic. Both trainers are well recognized and handling the subject for many years. Thus the Workshop was scheduled from 15th the 19th October, 2019 as per their convenience. Frequent discussions with these two subject experts enables us to locate the major modules to be included in the workshop in a sequence from simple to complex. Thus the basic modules were assigned to Dr. S. Kevin and the advanced modules were assigned to Dr. Vijayamohanan Pillai N. PLAN FUND ALLOCATION The College Council meeting held on 30 July, 2019 allocates an amount of Rs. 65000/ (Rupees Sixty Five Thousand Only) from the Plan fund sanctioned for FDP by the Directorate of Collegiate Education for the conduct of Workshop by the Research and Post Graduate Department of Commerce. The Department meeting held on 14th August, 2019 assigned Dr. K Pradeep Kumar, Associate Professor of Commerce and Dr.Lt. Sunilraj N.V., Assistant Professor of Commerce as Co-ordinator and Cocoordinator respectively. An Organising Committee consisting of Principal, Head of the Department and other Faculty members of Commerce was also constituted for preparing th Government College, Attingal Proceedings of Five day Workshop on Financial Econometrics from 15th to 19th October, 2019 programme schedule and necessary stages for the successful conduct of the programme. SELECTION OF PARTICIPANTS As the theme is focused on Teachers and Research Scholars, the organizing committee decided to invite all teachers and research scholars in various universities by clearly explaining the theme and various modules through the publicity materials. Personal emails were sent to Heads of the Department of Commerce of various Colleges and Universities to depute the teacher who is handling the subject or in need of training in the subject of Financial Econometrics. In addition, brochures were sent to all Colleges, Univerisity Departments and Self Financing Colleges by clearly specifying the sequence of modules included in different technical sessions. Participants are requested to register through e-mail by emphasizing their need for participation in the programme. Based on the response of the participants, 21 teachers from various Colleges of Kerala and 24 research scholars were screened and selected for participation in the programme. Selection memo is issued to all participants with strict stipulation on adherence to attendance in all days. In addition to that 9 faculty members of Commerce Department, Govt. College, Attingal and 5 full-time research scholars of the Research Centre and 30 M.Com students of the Department participated in the Programme. Thus a total of 89 participants attended the Five day workshop.

KEVIN Former Professor and Pro-Vice Chancellor, University of Kerala objective to provide numerical values to the Technical Session I parameters Origin of Econometrics of economic relationships. Econometrics applies statistical methods and Jan Tinbergen is considered by many to be one of the founding fathers of econometrics. He was a famous Dutch Economist. He won the first Nobel Prize in Economics in 1969 along with Ragnar Frish for developing applied dynamic models in analysis of economic processes. Ragnar Anton Kittil Frisch a Norwegian Economist is credited with coining the term in the sense in which it is used today. Econometrics means “economic measurement” Econometrics may be defined as the social science in which the tools of economic theory, mathematics, and statistical inference are to phenomena. the analysis [Arthur of S. economic Goldberger, Econometric Theory, John Wiley & Sons, New York, 1964, p. 1.] model is a simplified representation of a real world process. All the variables which the experimenter thinks are relevant to explain the phenomenon are included in the model. It is "the quantitative analysis of actual economic phenomena” Econometrics and Statistics relationships In ordinary statistics, the empirical data is collected, recorded, tabulated and used in describing the pattern in their development over time. Ordinary statistics is a descriptive aspect of economics. It does not provide either the explanations or measurement of the parameters of the relationships. Econometrics is typically used to explain how the economy works. It deals with the measurement of Econometrics deals with the measurement of economic explain phenomena and create models. A Econometrics differs from ordinary statistics. What is Econometrics? applied mathematical techniques to economic data to (e.g., price and demand) . It is an integration of economics, mathematical economics and statistics with an economic relationships. Basic Tool in Econometrics A basic tool for econometrics is the multiple linear regression Government College, Attingal model.

(3000,3500, 4000,4500,5000) expenditure relationships between variables are Correlation and Regression. Correlation Studies the association between variables that may be related. A measure of covariation. Indicates magnitude and direction of covariation. Karl Perason‟s Coefficient of Correlation (r) is the widely used measure of correlation. r may be positive or negative.r varies from (-)1 to 1. Thus Regression analysis is a set of statistical methods used for the estimation of relationships between a dependent variable and one or more independent variables. Can be utilized to assess the strength of the relationship between variables and for modeling the future relationship between them. Coefficient of determination is r square (R2). Regression Measures the extent of variation explained by variations, such as linear, multiple linear, and the relation. In research, universe parameters are nonlinear. The most common models are inferred from sample statistics.

If it is nonstationary, it is not possible to generalize it to other time periods. If we have two independent non-stationary series, then we may find evidence of a relationship when none exits (i.e. spurious regression problem). The relationship will be genuine only if the two series are cointegrated. Correlogram Autocorrelation is the correlation between observations of the original time series and the Economic and Financial Time Series Examples: exchange rates, share prices, These are often trending and consequently nonstationary. It is important to test whether the economic or financial time series is non- lagged time series. The lagged time series may be created with lag of one time period or more than one time period.

Unit Root Test A statistical procedure used to test whether a time series is non-stationary and possesses a unit root. A series which has a unit root is non-stationary. Augmented Dickey-Fuller (ADF) test is commonly used to test the null hypothesis that a time series has a unit root and is non-stationary.

A stationary time series is integrated of order zero, denoted as I(0). Inference Cointegration The ADF test statistic (tau value) is (-) 1.17544. As this value is not more negative than the critical values, the null hypothesis cannot be rejected. Null hypothesis that the time series has unit root and is nonstationary is accepted In the case of two independent non-stationary series, we may find evidence of a relationship when none exists (i.e. spurious regression problem). The relationship will be genuine only if the two series are cointegrated. It becomes necessary to examine the existence of Meaning of Unit Root Test cointegration in such cases. In an autoregressive (AR) statistical model of a time series, the AR parameter is assumed to be 1. In a data series Yt modelled by Yt+1 = aYt + et Concept of Cointegration An old woman and a boy are on random walk in the park. Information about the boy‟s location tells us nothing about the old „a‟ is an unknown constant woman‟s location. There is no cointegration Unit root test would be a test of the hypothesis that a = 1, against the alternative that „a‟ is less than 1. If the time series has unit root (a = 1), the series is said to be nonstationary. Integrated Time Series An old man and his dog are joined by a leash. The man and the dog are each on a random walk. But they cannot wander too far from each other because of the leash. The random processes A nonstationary time series is known as an integrated time series or series with stochastic trend. It could be made stationary by differencing (that is, subtracting the preceding value from it current value). If a time series becomes stationary after differencing it once, it is said to be integrated of order one, denoted as describing their paths are series are whether the cointegrated. Testing for Cointegration To test whether cointegrated, we two I(1) examine residuals are stationary or I(0). In the case of two nonstationary I(1) series, Y and X, if the residuals of the regression Yt = α + β Xt + et are I(1). If it has to be differenced twice (i.e., Government College, Attingal Proceedings of Five day Workshop on Financial Econometrics from 15th to 19th October, 2019 stationary, then the variables are said to be cointegrated.

The two series are financial time series and hence stationarity of the series have to be examined. If the series are nonstationary, then existence of cointegration has to be examined before the regression results can be relied upon. Results of Engle-Granger Cointegration Test Inference The two time series of Nifty values and Asian Paints share prices are nonstationary. The Residual series of the regression between the two series is also non stationary. Cointegration exists only if the residual series is stationary. There is no cointegration between the two series, as the residuals series is nonstationary. The regression results are not reliable, in the absence of cointegration.

Futures prices of Asian Paints are taken as the dependent variable Government College, Attingal Proceedings of Five day Workshop on Financial Econometrics from 15th to 19th October, 2019 Inference The two time series of Spot prices and Futures prices of Asian Paints are nonstationary. The Residual series of the regression between the two series is stationary. Cointegration exists if the residual series is stationary. There is cointegration between the two series, as the residuals series is stationary. The regression results are reliable, as the variables are cointegrated. Government College, Attingal Proceedings of Five day Workshop on Financial Econometrics from 15th to 19th October, 2019 TIME SERIES REGRESSION Dr. P.N. Harikumar Associate Professor, Catholicate College, Pathanamthitta INTRODUCTION Time series is a set of observations generated sequentially in time. If the set is continuous then the time series is continuous. If the set is discrete then the time series is discrete. Generally discrete time series are more adopted in Econometric studies. “Sequential in time” is only to mean successive observations and hence a sequence of observations observed over a space may also be considered as a time series. Generally the term „Time Series‟ is used to refer this kind of data also. Analysis of discrete time series is relatively easier. Usually time series are observed over equal interval of time. However, this is not a restriction on the scope of time series analysis. The usage of time series models is twofold: 1. Obtain an understanding of the underlying forces and structure that produced the observed data 2. Fit a model and proceed to forecasting and monitoring. Examples of Time series data Business and Economics : weekly share prices, monthly profits, sales forecasting, budgetary analysis, stock market analysis, yield projections Meteorology: daily rainfall, wind speed, temperature Sociology : crime figures, employment figures DESCRIPTIVE UNDERLYING FORCES A time series is said to be a consequent effect of four possible forces acting at a point of time. They are trend, seasonal variation, oscillation and random component. A Time series is said to be an effect of these four components and the researcher may choose from the two alternative models ie. Additive or multiplicative models. In an additive model, these forces or components are added up to give time series. This means that at every point of time these four forces may be in operation and hence there may be an effect due to Trend (T), an effect due to Seasonal Variation (S), Oscillation (O) and Random component (R) and the value of observation of the variable at that point of time is taken as the sum of these four effects. It the variable is taken as y and its observation at time „t‟ is denoted by yt then it is assumed to be given by yt = Tt+St+Ot+Rt. Similarly the alternative model will be obtained by multiplying these effects to get yt. A study of time series aims at identifying the possible contributions of these effects and after eliminating these effects the remaining series called as „Residual Series‟ is taken up for high end solutions using different types of models. However, the identification of effects due to Trend and Seasonal Variations are highly valuable in Econometric Studies. Definitions Trend: A smooth movement of observations either upwards or down wards over a Government College, Attingal Proceedings of Five day Workshop on Financial Econometrics from 15th to 19th October, 2019 relatively long period of time is called a Trend. Possible reasons for trend in observed series may be attributed to development of dependent factors like technology, health and the like. Seasonal Variation : In certain cases of time series a systematic behavior of up and down movement can be observed repeatedly over a fixed period of time interval. As an example, textile sales may be seen to vary in a systematic manner over a year. This type of series may provide valuable information that may be useful in future predictions. Oscillations: Suppose a time series is devoid of effects due to trend and seasonal variation, then it may be observed to oscillate around a constant value. A look at recordings from ECG or variation in the movement of sensex index over a normal day may be examples. Random Component: Above all the other effects having a possibility of explanation, there may be a large number of forces acting and adding a random effect to the series. A study of time series is directed at the estimation of explainable effects due to Trend and Seasonal Variation; eliminate them from the observed series; try for explanation of the residual series using statistical models. In order to achieve them, there are conventional methods having a well built computational capability. Also, there are high end methods involving modeling under different assumptions. Use of time series is an enchanting area in Time Series Analysis. The types of analyses vary with respect to the type of the series. Empirical work assumes that the underlying time series is stationary. The second concept concerned with time series analysis is Auto Correlation. Presence of auto correlation may turn a time series into Non Stationary. Using Regresson with two time series may produce Spurious or nonsense regression. The Rsquare may be very high, yet the regression will be meaningless. The key concepts to be considered will be the concepts called Stochastic Processes, which are taken as concepts generating the time series. Stationary Processes, Pure Random Processes, Non-stationary Processes, Integration Variables, Co-integrtion and Unit Root Test are explained in sequence. Random Process or Stochastic Process is a collection of random variables, usually ordered in time. Such processes can be defined on other spaces also. They may be further classified into discrete and continuous depending upon the observations are in continuum or at discrete points. Stationary Stochastic Process: A stochastic process is said to be stationary if its mean and variance are constant over time and the covariance between two time points depends upon only the time difference and not on the choice of the time points. A majority of time series assumes that the underlying process is stationary. If a time series is not stationary in this sense, it is called as non-stationary. For example Random Walk Model, used in the study of stock prices comes under this head. Random Walk Model is considered in two ways; Random Walk Model with Drift and Random Walk Model without Drift. Let Yt be the variable observed at time point „t‟, then the RWM is stated as Yt= Yt-1 +ut Where ut is an error term with mean 0 and variance σ2.It can be observed that this results in Y1 = Y0+u1 Government College, Attingal Proceedings of Five day Workshop on Financial Econometrics from 15th to 19th October, 2019 Y2 = Y1+u2 = Y0+u1+u2 Y3 = Y2+u3 = Y0+u1+u2+u3 As the time goes on increasing, the mean will remain the same but the variance will go on increasing making the series non-stationary. Similarly, the RWM with drift can be written as Yt=ᵭ +Yt-1+ut where ᵭ is the drift parameter. The difference between Yt – Yt-1 = ᵭ+ut. drifts upwards or downwards depending upon the value ᵭ. Here, both mean and variance go on increasing over time, suggesting that the series is non-stationary. Unit Root Stochastic Process: Suppose we write the RWM as Yt=ρYt-1 +ut where -1 ≤ ρ ≤ 1 is the classical autoregressive model. When ρ is 1, the model is called Unit Root Stochastic Process. The model leads to a non stationary series observed earlier. Thus non-stationarity, Random Walk and Unit Root stochastic process are equivalent concepts . If lρl ≤1, the model leads to stationary series. Integrated Stochastic Process: RWM is but a specific case of a more general class of models called as Integrated Model. It was claimed in the last part that the RWM without drift is non-stationary. But its first difference (Yt-Yt-1) = ∆Yt=ut is stationary. Hence, we call RWM without drift as „an Integrated Process of Order 1” Similarly, if the difference of the first difference is stationary process is called as Integrated process or order 2. In general if pth order differences of a series results in a stationary series, the process is called as „Integrated of order p‟ denoted as I(ρ). Co-integration: The regression of a nonstationary time series on another nonstationary time series may produce a spurious regression. Let us suppose that we consider the Y and X time series. Subjecting these time series individually to unit root analysis and suppose you find that they both are I(1); that is they are auto-regressive of order 1 with autoregressive coefficient being 1; that is, they contain a unit root. Suppose, then, that we regress Y on X as follows. Yt = β1+β2Xt+ut (1) Let us write this as ut = Yt-βt-β2Xt (2) Suppose we now subject ut to unit root analysis and find that it is stationary; that is. It is I(0). This is an interesting situation, for although Yt and Xt are individually I(1), that is, they have stochastic trends, their linear combination (2) is I(0). So to speak,the linear combination cancels out the stochastic trends in the two series. If you take consumption and income as two I(1) variables, savings defined as income – consumption could be I(0). As a result, a regression of consumption on income as in (1) would be meaningful. In this case we say that the two variables are cointegrated. A number of methods for testing cointegration have been proposed in the literature. Two simple methods are the DF or ADF unit root test on the residuals estimated from the co,-integrating regression and the Co-integrating regression Durbin-Watson test. Engle and Granger have calculated the critical significance values. Therefore, the DF and ADF tests in the present context are known as Engle-Granger (EG) and Augmented Engle-Granger (AEG) tests The Unit Root Test : A test of stationarity that is popular is the Unit Root Test. For this purpose Dickey and Fuller have developed a test for δ =0. The associated statistics is called as Tau-statistics using simulation Government College, Attingal Proceedings of Five day Workshop on Financial Econometrics from 15th to 19th October, 2019 exercises and prepared extensive tables providing critical values. This is called as DF test for stationarity. This test assumes that the error term ut is uncorrelated. But in the case where ut are correlated, Dickey-Fuller developed another test called Augmented Dickey Fuller test (ADF test). This is done with a modification of the considered model by adding the lagged values of the dependent variable. Still δ=0 is tested and the same tables for DF test can be used here also. Approaches to Time Series Forecasting There are different approaches to forecasting with time series such as Exponential Smoothing, Single Equation Regression Models, Simultaneous Equations Models, ARIMA Models and VAR Models. The ARIMA Models coming under Box-Jenkins Methodology include Auto-Regressive(AR), Moving Average (MA) and Auto Regressive Integrated Moving Average (ARIMA) Models. Here a brief view of these techniques is given. Auto Regressive (AR) Process: Let Yt be the variable at time „t‟ in the process. Then in some situation, this may linearly depend upon its value in the preceding time point or points. This can be written as Yt=α1Yt-1+ut, which is called as a first order Auto Regressive Process (AR(1)). The current year GDP may depend upon last year GDP. The model may be written in a modified way as (Yt-δ)=α1(Yt-1-δ)+ut, where δ is the mean of pth order Auto Regressive Process (AR(p)). Moving Average (MA) Process: In the same way, consider that realization of a variable at a time point „t‟ is given by a disturbance of a value, say average of a stationary aprocess, the model can be specified as Yt=µ+ut, where ut is a random variable with mean 0 and variance σ2, called an error term (with normal distribution for the error term, it is called as white noise). Extending this idea, that the error at time „t‟ is a weighted average of previous and current errors, then the model can be written as Yt= µ+β0ut+β1ut-1, called the first order Moving Average process. Extending this ideas, to „q‟ previous time points we get a model called as qth order Moving Average Process MA(q). Auto Regressive Moving Average (ARMA) Process: If there is a reason to believe that a process Yt has the characteristics of both AR and MA process, then another model can be obtained with ARMA models, given by Yt=θ+αtYt-1+β0ut+β1ut-1 Notice the presence of lag of order one only for AR and MA components. This is called ARMA(1,1) Process. In general, one can define ARMA (p,q) processes, where the AR process is of order „p‟ while that of MA of order „q‟. Auto Regressive Integrated Moving Average (ARIMA) Process: It is already stated that the analysis is comfortable when the series is a stationary series. If the given series is stationary, it is called I(0), „Integrated of order 0‟. Generally, the given series is difference for required number of successive repetitions to get into stationarity. If a given series is differenced for „d‟ times before applying ARMA (p,q) model, then the resulting model is called as ARIMA(p,d,q) Model. In order to estimate the model and use the results for forecasting, Box-Jenkins method is used. While considering ARIMA (p,d,q0 model, knowledge about p,d,q are not Government College, Attingal Proceedings of Five day Workshop on Financial Econometrics from 15th to 19th October, 2019 known. Hence, the most important issue is that of deciding these constants. Box-Jenkins methodology consist of four steps for analyzing a series and uses the results for forecasting with ARIMA(p,d,q) model. They are identification, Estimation, Diagnostic Checking and Forecasting. This is a high end model activity which needs expert assistance. ARCH and GARCH Models Auto Regressive Conditional Heteroscedasticity (ARCH) and Generalised Auto Regressive Conditional Heteroscedasticity (GARCH) models are models useful in the study of time series exhibiting Volatality Clustering. By volatility clustering it meant that the behavior of the series showing wide swings for a time interval followed by periods in which there is relative calm. This implies that the variance of the series varies over time. This heteroscedasticity or unequal variance may have an autoregressive structure, ie variance observed over different points of time may be auto correlated. Generally Xt2 is taken as a measure of volatility. Accepting this, one way of verifying such volatility clustering will be to model the behavior using AR(1) model, Xt2= β0+β1X2t-1+ut in the simplest case, where ut is the usual error term. If β1 is 0, there is no volatility; hence a test is performed for the hypothesis β1=0 with the usual test. Depending upon need higher order models can be used. If the hypothesis is rejected, the presence of volatility clustering is accepted then the series presents an ARCH situation. What should be done in that case? In such situations, the regression is obtained by the Generalised Least Square Method. There are many software providing comfortable computation here. It is to be noted that a significant Durbin Watson Statistic should be further followed to check for ARCH effect also. With this addition to regression models, other improvements started to come in the area that has resulted in a more general format for ARCH models called as Generalised Autoregressive Conditional Heteroscedasticity (GARCH) model. We consider simple GARCH(1,1) model; in fact hese are certain principles which can be adopted for any model. GARCH (1,1) can be written as σt2=α0+α1ut-12+α2σt-12 This implies that the conditional variance of „u‟ at time‟t‟ in the model, where „u‟ is the error term, depends upon not only on the squred error term in the previous time‟t-1‟ (as in ARCH) but also on its conditional variance of the previous time period.

Government College, Attingal Proceedings of Five day Workshop on Financial Econometrics from 15th to 19th October, 2019 PERFORMANCE EVALUATION OF ENTREPRENEURSHIP DEVELOPMENT SCHEMES OF NATIONAL HANDICAPPED AND FINANCE DEVELOPMENT CORPORATION Dr. SHANIMON S Assistant Professor Government College, Attingal Abstract The growth and development of all economies highly depend on entrepreneurial activity. Entrepreneurs are the nerves of economic development as they provide a source of income and employment for themselves. They create an atmosphere of employment generation for others; produce new and innovative product and services. Entrepreneurial supportive environments are essential for entrepreneurship development and are evolving all around the developing economies. An idea of entrepreneurial environment has five metrics, such as easy access to funding, entrepreneurial culture, entrepreneurial supportive regulatory measures, entrepreneurial supportive mechanism and entrepreneur friendly policies. The public and private sector have an equal role to the development of entrepreneurial eco-system. There are four factors necessary for entrepreneurial opportunities such as factor-driven entrepreneurship, efficiency-driven entrepreneurship, innovation-driven entrepreneurship, and necessity-driven entrepreneurship. Entrepreneurship has been considered as the backbone of economic growth. The level of economic activities of a country largely depends on the level of entrepreneurial activities in that country. Entrepreneurs are not born but can be created and nurtured through appropriate interventions in the form of entrepreneurship development programmes. In the modern competitive world a number of opportunities emerged from the evolving Information Technology Revolution. A large part of the population generally lags behind in taking advantage of emerging IT revolution. Therefore, there is a need to provide skill development through entrepreneurship development to such people in order to bring them to mainstream of economic development. Key Words: Entrepreneurship, Economic Development. 1.1 Introduction of the socially disadvantaged groups especially Entrepreneurship development programmes should be designed to upgrade existing skills and to create new skills by organising various technical training courses to the mainstream society.

Government College, Attingal Proceedings of Five day Workshop on Financial Econometrics from 15th to 19th October, 2019 TRENDS IN GLOBAL AQUACULTURE PRODUCTION Dr. ANITHA S. Associate Professor Government College, Attingal Abstract Aquaculture is the farming and husbandry of aquatic creatures under regulated or semi-regulated environmental conditions. These organisms may be fishes, crustaceans, molluscs, aquatic plants and animals. Global Production from capture fisheries showed a declining trend in the past few decades. Despite the mechanism of fishing techniques, catch per unit effort declined and unit cost of production increased. The basic reason for the declining rate of growth in fish production is attributed to over exploitation of scarce fishery resources. This necessitated a shift on emphasis from development of capture fisheries to development of culture fisheries. Scientific aquaculture- a bio technology to boost fish production through fish culture has become popular in major fish producing countries of the world. This research paper analyses the gloabal trends in aquaculture production based on the valid database of Fisheries Global Information Systems (FIGIS).

Global Aquaculture Production Trend global aquaculture production for the 20 years from 1997 to 2016 under review. The regression model reveal that the time series trend is linear and increasing annually at the rate of 2.7781 Million tons. Even though the model fitness indicator R2 shows higher value, the validity of the model need to be tested for all assumptions in Ordinary Least Squares. Thus a pure econometric time series analysis may improve the model through various tests of validity. Reference The world aquaculture production increased from 30.23 million tons to 80.4 million tons over a period of 20 years from 1997 to 2016. The data over this period seem to show a linear growth in global aquaculture production. Using the function y = a+bx, the equation estimated using regression tool, results in b = 2.7781, a = 0.5523, which is 2 valid with a significant R value = 0.978.Thus in every year the a marginal increase in production is 2.7781 Million Tons.

The historical data on index closing price was used to develop several ARIMA (Autoregressive Integrated Moving Average) models by using Box-Jenkins time series procedure and the adequate model was selected according to four performance criteria: Akaike Criterion, Schwarz Bayesian Criterion, Maximum Likelihood and Standard Error. The paper presents the process of building stock price predictive model using ARIMA Model. Published stock data obtained from NSE (National Stock Exchange) is used with stock predictive model developed. Therefore, Monthly data from January 2001 up to December 2019( 228 observations) is used for this study. The results obtained revealed that ARIMA model has high potential in short run prediction and will be helpful to investors in stock market.

This is because of the central role of the financial system in mobilizing savings and allocating same for the development process. This study examined financial deepening and economic development in India between 1995 and 2017. The study made use of secondary data, sourced for a period of 22 years. The two stages least squares analytical framework was used in the analysis. The study found that financial deepening index is low in India over the years. It was also found that the nine explanatory variables, as a whole were useful and had a statistical relationship with financial deepening. But four of the variables; lending rates, financial savings ratio, cheques cleared/GDP ratio and the deposit money banks/ GDP ratio had a significant relationship with financial deepening. The study concluded that the financial system has not sustained an effective financial intermediation, especially credit allocation and a high level of monetization of the economy. Thus the regulatory framework should be restructured to ensure good risk management and corporate governance in the system. Key Words; Financial Sector, Corporate Governance, Financial Reforms, Financial Savings, Financial Market, Gross Domestic Product, Financial Deepening Introduction The reforms in the financial system in India which heightened with the 1991 deregulation, affected the level of financial deepening of the country and the level relevance of the financial system to economic development. However, the rapid globalization of the financial markets since then and the increased level of integration of the Indian financial system to the global system have generated interest on the level of financial deepening that has occurred. The financial system comprises various institutions, instruments and regulators. According to the Reserve Bank of India the financial system refers to the set of rules and regulations and the aggregation of financial arrangements, institutions, agents, that interact with each other and the rest of the world to foster economic growth and development of a nation. The financial system serve as a catalyst to economic development through various institutional structures. The system vigorously seek out and attract the reservoir of savings and idle funds and allocate same to entrepreneurs, businesses, households and government for investments projects and other purposes with a view of returns. Government College, Attingal Proceedings of Five day Workshop on Financial Econometrics from 15th to 19th October, 2019 This forms the basis for economic development. The financial system play a key role in the mobilization and allocation of savings for productive, use provide structures for monetary management, the basis for managing liquidity in the system. It also assists in the reduction of risks faced by firms and businesses in their productive processes, improvement of portfolio diversification and the insulation of the economy from the international economic changes. The system provides the necessary environment for the implementation of various economic policies of the government which is intended to achieve noninflationary growth, exchange rate stability, balance of payments equilibrium foreign exchange management and high levels of employment. The Indian financial system can be broadly divided into two sub-sectors, the informal and formal sectors. The informal sector has no formalized institutional framework, no formal structure of rates and comprises the local money lenders, thrifts, savingsand loans associations.This sector is poorly developed, limited in reach and not integrated into the formal financial system. Its exact size and effect on the economy remain unknown and a matter of speculation. The formal sector, on the other hand, could be clearly distinguished into the money and capital market institutions. The money market is the short-term end of the market and institutions here deal on short term instruments and funds. The capital market encompasses the institutions that deal on long-term funds and securities. The regulatory institutions in the financial system are the Ministry of Finance, the Reserve Bank of India as the apex institution in the money market and the SEBI as the apex institution in the capital market The process of financial sector reform consists of the movement from an initial situation of controlled interest rates, poorly developed money and securities market and under-developed banking system, towards a situation of flexible interest rates, an expanded role for market forces in resource allocation, increased autonomy for the central bank and a deepening of the money and capital markets. The link between financial sector stability and growth is, explained by increased market depth, which potentially increases market efficiency. It also reduces risks through the elimination of weak institutions. Need and Significance of the study Financial sector reforms seek to develop an efficient framework for monetary management. This encompasses efforts to strengthen operational capacities of the banking system, foster efficiency in the money and securities markets, over-haul the payments system and ensure greater autonomy to the central bank in formulating and implementing macroeconomic policies. Thus, there is the need to deepen the financial sector and reposition it for growth and integration into the global financial system in conformity with international best practices. This study is important at this level of economic development when efforts are being made to reposition the financial system to enable it play key roles in economic development of Government College, Attingal Proceedings of Five day Workshop on Financial Econometrics from 15th to 19th October, 2019 India. The study essentially seeks to examine in an empirical manner, the nature of financial deepening in India since the onset of financial reforms in 1995up to 2017 when the banking consolidation took root in India. The study seek to ascertain the critical factors that have affected the level of financial deepening in India and to ascertain if there is observable growth in the financial deepening index (money supply to GDP) ratio in India. The MODEL Specification A model is identified if it is in a unique statistical form enabling unique estimates of the parameters to be subsequently estimated from a sample data. In this study, the model used by Gosselin and Parent in their study of the financial deepening function in pre and post financial reform periods in India. In their specifications, six explanatory variables were used in investigating financial deepening. In this study, ninevariables were used. In this model Financial Deepening(M/GDP)depends on,Financial Savings/GDP ratio (FS/GDP) Private Sector Credit/GDP (PSC/GDP) value of Cheques Cleared to GDP ratio (CHQ/GDP), value of Cheques Cleared to Money Supply (CHQ/M) the Rate of Inflation (INFLAT), Prime lending rates(PLR) the intermediation ratio i.e. Currency outside Banks to Money Supply (COB/M) and the Dummy. This model is given as M/GDPit =f(PLR it ),FS/GDPit,CHQ/GDPit ,C HQ/MINFLATit ,PSC/GDPit, DMBA/GDPit, COB/MS2 + DUM. Methodology The data used in this study were sourced from the Reserve Bank of India publications and those of the Bureau of statistics. The data was for the period1995– 2017. The period chosen for the study encompasses the phases of the major reforms in the financial system and the period of consolidation of the banking and insurance systems in India. In the present study, financial deepening defined as the ratio of money supply to GDP, is a function of the value of cheques cleared to GDP, value of cheques to money supply, ratio of private sector credit to GDP, financial savings to GDP, rate of inflation, real lending rates, deposit money bank assets to GDP, Currency outside Banks to money supply .and the Dummy. The equation specified for the study was estimated using the stepwise least squares regression method. The model assists us to determine the T values and theFvalueswhichwereusedtotestthesignifica nceoftheequationspecified. The data used in the regression runs are as shown in Tables 1.Theseareabsolute aggregates for each variable obtained for theperiod1995–2017 (22years). The inflation rates are expressed in percentages, while the savings rates are used as a proxy for interest rates. These rates are also in percentages. The private sector credits(PSC) are aggregate values and so to financial savings (FS). The introduction of the dummy variable seeks to capture the influence of political instability on the operations of financial institutions and this to a large extent influences financial deepening. Values of 0 to 1 are assigned to the various years: 0 representing mild Government College, Attingal Proceedings of Five day Workshop on Financial Econometrics from 15th to 19th October, 2019 instability, while 1 represent high levels of instability. The data were subsequently converted to the relevant ratios as shown in table 1. To test for stationarity and cointegration, the Durbin – Watson (SBDW) test was adopted. It is important to note that the present of co-integration in a model means that long-run equilibrium relationship exists among the nonstationery variables. Results Regression Results The summary of financial deepening result from the Two stage regression analysis is shown in the model summary below. Model Summary R = 0.972 2 R = 0.946 2 Adj R =0.906 Std error of estimate = 0.88808 Durbin-Watson = 1.551 F value = 23.62 d.f. = 22 The coefficient of correlation R and Coefficient of determination R2 measure the explanatory power of multiple regression models. From the results, there is a high coefficient of correlation (97.2percent). The implication is that the variables in the equation are useful for explaining the level of financial deepening that has occurred between 1995 and 2017. There is also a highly significant coefficient of determination (94.6 percent). The standard error of the estimates also known as residual standard deviation has a value of 1.77708. The Fstatistic value is found to be 23.62. The F value is significant at the 5 percent level. The overall fit of the regression model measured by the F- statistic, is statistically significant at this level. The Durbin Watson (DW) statistic of 1.551 indicates that there is no problem of serial correlation in the regression model. This is a case of positive serial correlation. Also, multicolinearity which often present in cross-sectional data seems to be non existent in the model. In Table 2 the estimation results using the nine explanatory variables are presented at alpha equal to 0.05 level of significance and also at 0.10. It was found that the financial savings ratio, interest rates, cheques cleared to GDP ratio and, Deposit Money Banks Assets to GDP ratio are very useful explanatory variables. Political instability is not significant at both the 5 percent and 10 percent levels. The implication of the findings is that although the financial structure had enhanced the level of financial savings and thus affected the level of financial deepening positively, the financial system has not been efficient in resource allocation evidently. Here, the process of intermediation in the system is not efficiently done. Although the financial system has not grown tremendously in size and structure this has not been translated in the provision of loans and credits especially to the real sector of the economy.

Conclusion The study was concluded that the level of financial deepening in India has remained relatively low in spite of the various reforms and institutional changes put in place by the: monetary authorities. It is also evident that the low level of monetization of the economy, the high rate of inflation and the level of private sector credits have negatively affected the level of financial deepening in India. Although the level of interest rates have remained very high, the level of private sector credits have not sustained the desired level of new investments necessary to facilitate growth in the economy. However, there is an urgent need to sustain a higher level of macroeconomic stability in India, reduce the high incidence of non performing credits ensure that private sector credits are channeled to the real sector of the economy, enhance the level of corporate governance in the financial system and also strengthen risk 3. 4. 5. 6. 7. 8.

Assistant Professor Government College, Attingal Abstract India with its unique rich payment ecosystem is now emerging as a global one in innovative digital payment systems. The Reserve Bank of India and the Government have expressed a vision of a less cash civilization and guided its evolution with feet stick on the ground. The growth of financial services in India has largely been driven by the banks. The regulator as well as the banks has led the initial push, development and support of digital payments infrastructure. Non-banks have entered the market and expanded the range of payment services available to the Indian consumer backed by their strength in technology and customer oriented innovation. Banks and non-banks are partnering to offer the combination of trust and innovation to the Indian consumer. This will resulted in a recent growth in the number of digital payments, should continue.

Earlier, in the state of Kerala, private buses were seen as a symbol of status. This industry provides more revenue to the government directly and indirectly and also creates more employment opportunities. But now this industry has become a headache to the owners and some are still continuing services as part of commitment. In September 25 2018 RTA Kollam has faced surrendering of 14 route permit in a single day. If this scenario continues Kerala economy as well as the state will be facing many problems from this sector. Therefore, steps should be taken by the government and the authorities to find solutions in this sector.

Now, due to a fall in natural aquaculture activities include fuel and power, availability of wild seeds, the farmers basically lease rentals, if any, insurance premium, interest depend on hatchery-produced seeds. The quality on the loan taken for practising aquaculture, of the seeds is very important for success in transportation cost, etc. The cost of these aquaculture. The governmental agencies, expenses varies in different farms. Thus, the through their own hatcheries, provide seeds at total of these costs, titled as other expenses, is subsidised rates to the farmers, to encourage considered for the purpose of anlysis to measure aquaculture in Kerala. So the second major cost its impact on revenue from aquaculture. incurred for aquaculture is the seed cost. Government College, Attingal Proceedings of Five day Workshop on Financial Econometrics from 15th to 19th October, 2019 RESULTS AND DISCUSSION It may be noted that in a particular case, it is not necessary for all these factors (cost of aquaculture activities) to exist together.

The models provide significant R2 value in all cases with positive coefficients. From the regression coefficients the three most important variables determining revenue are identified as Seed, Feed and other expenses.
