Chapter 1: Introduction to Labour Market Economics Keywords Aggregate or time series data: data describing macroeconomic variable such as unemployment or inflation; there is a one-to-one correspondence between the time period and a data value, as the value vary over the dimension of time Coefficient: a parameter of a regression model; a constant scalar value that, multiplied by the economic variable(s), gives the effect of explanatory variable on the variable being explained Cross-section micro data: data describing attributes of microeconomic units such as firms and workers; there is a one-to-one correspondence between the unit of observation and a data value; the values vary over the dimension of economic actors at the same time period Dualism: an analytical perspective that is an alternative to the neoclassical supply and demand approach; the labour market is segmented into two parts: the core and the periphery Employment: the market quantity of labour that is hired and inputted into the production process Equilibrium: the state of an economic model; such as the supply and demand framework, in which there are no forces action to change the values of the economic variables Institutionalism: an analytical perspective that is alternative to the neoclassical supply and demand approach; plays down the importance of the economic forces of supply and demand, and plays up the role of institutions, conventions, customs, social mores, and political forces Involuntary unemployment: unemployment occurs when a candidate is able and willing to work but currently without work Labour Demand: the relationship between the amount of labour that firms are willing to hire over a given time interval and the wages level offered by workers Labour market outcome: the phenomena generated from the labour market as a result of the forces of labour supply and labour demand; primary examples are wages, employment levels, and unemployment levels Labour shortage: is an economic condition in which there are insufficient qualified candidates to fill market place Labour supply: the relationship between the amount of work that workers are willing to provide over a given time interval and the wage level offered by the firm Market clearing Model: the supply and demand model equilibrium output and prices determination; the market is said to clear when the equilibrium price is reached Multiple regressions: a regression model having more than one explanatory variable Neoclassical economics: the analytical approach used in mainstream economics: Self-interested economic actors produce, consume, and exchange goods and services in markets Neoclassical supply and demand model: the analytical framework used for most of the field of labour markets; based on the self-interested choices of firms and workers who exchange services in labour market Ordinary lest squares: a statistical or econometric technique employed to estimate the values of parameters of regression models having a linear form; applicable under certain conditions Parameter: an element of a regression model that links the economic variables; typically it takes the form of a slope coefficient or the intercept term R-squared: the proportion of the fluctuations in the dependent variable of a regression model that can explain by fluctuations in the independent variable Regression analysis: a tool for empirical analysis in which fluctuation in the dependent variable are explained as a function of fluctuation in one or more independent variable; the regression model is a mathematical equation describing the relationship between a dependent variable and one or more independent variables; the primary elements are parameters and variables Sampling errors: the error in the estimation process that stem from drawing data from a sample not totally representative of the population Standard error: a statistical measure of the dispersion of an economic variable or an estimator for a parameter Statistical significance: an indication that the true value of a parameter of the regression model is different from zero T-ratio: the ratio of the estimated parameter to the estimate standard of error of the estimated parameter Unemployment: human resources that are not employed on the job market; such workers are actively searching for work and are willing to work at the going market wage Wages/Wage rate: the market price for a unit of labour Main actors/ participants in labour market: Individuals: make decisions concerning how they will earn a living Firms: make decisions about how much and what type of labour they will hire Governments: establishes the environment in which employees and employers interact; effect on labour market Positive labour market behaviour: obtaining a job/ wage increases/ generous pension Negative labour market behaviour: Unemployed/ Permanent displacement/ discrimination Labour supply Dimensions Increase/decrease variables of population Labour force participation and for those that participate Education, training, and health Work effect and intensity Labour demand Dimensions Firm vary their demand for labour in response to changes in the wage rates and other elements of labour cost Dimensions of labour supply and demand interactions determine key market outcomes such as: Wages Employment and unemployment Labour shortage These outcomes are also influenced by unions, collective bargaining and legislative interventions Various Wage structure differentials Occupation Industry Region Personal characteristics Unemployment is analyzed at both micro/macroeconomic levels. At the micro level, the emphasis is on theories of job search, implicit contracts and efficiency wages, and the impact of unemployment insurance. At macro level, the relationship between wage changes, price inflation, productivity, and unemployment is emphasized. Supply and demand Model Neoclassical supply and demand model: the analytical framework used for most of the field of labour markets; based on the self-interested choices of firms and workers who exchange services in labour market 2 key elements: 1. Behavioural assumptions and how buyers and sellers respond to prices and other factors 2. Assumptions about how buyers and sellers interact, and how the market determines the level and terms of exchange
