COURSE DESCRIPTION:
Intermediate Microeconomics is an advance treatment of the concepts that you have already been
exposed to in your first course in economics. It is predominantly a theory-oriented course and as such
tends to be somewhat abstract and technical. It is a course designed primarily to economic majors with the
sole intent of teaching them the ‘neoclassical economics ways of thinking’ on resource allocations (i.e., the
apportionment of scarce resources among competing uses) in a rigorous and comprehensive manner. More
specifically, this is a course where students actually, through repeated mathematical derivations and
graphical exhibits, learn the broad and wider applications of those analytical approaches that are so
profoundly unique to modern economic science, such as equi-marginal equilibrium conditions, partial
equilibrium analysis, constrained optimization, and game theoretic (i.e., a strategic decision-making
techniques). In addition, where it is appropriate, concerted efforts are made to highlight the relevance of the
insights gained from microeconomics theories to public policies and the decision making processes of
households and business concerns.
The course is organized in four parts. Part I starts by a formal analysis of the general implications
of resource scarcity. This is then followed by providing a detailed outline of the basic ‘axiomatic’
assumptions of modern microeconomic theory. In this regard, attention is directed to enumerate the specific
social (people’s behavior), institutional, and resource conditions that are necessary for the existence of a
‘perfect’ market condition – a situation where no one single economic entity (a buyer or a seller) can be able
to influence market price. This part ends with brief remarks that are intended to show the implication(s) of
deviating from each core assumption for perfect market.
Part II examines the theory of consumer choice. The objective here is to develop a general
framework of analysis that would allow us to develop rules for the careful measuring and balancing of costs
and benefits of particular activities undertaken by individual consumer’s (such as buying goods and
services, selling labor services, lending money) with a clearly stated objective to maximize utility (gain
happiness). This general framework of analysis will also allow us to delve into the basic factors behind the
determinants of the: (i) demand for final goods and services, (ii) supply for labor, and (iii) supply for
loanable funds—financial capital.
Part III deals with the theory of the firm. In this section, several general theoretical frameworks are
developed to understand the technological (i.e., production functions) and economics (i.e., cost and revenue
functions) that influences the decision of a firm in both the short and long run settings. Once this is done,
the next step is to develop rules for careful measuring and balancing of costs and benefits of particular
1
activities (such as buying input, producing output, borrowing money) undertaken by individual producer
with a clearly stated objective to maximize returns. The ultimate goal in the theory of the firm is to
understand the determinants of: (i) the supply for final goods and services, and (ii) the demand for factors of
production, such as labor and capital.
Part IV, starts with the formal evaluation of the long-run performance of an economy under a
perfectly competitive market structure—the so-called ‘invisible hand theorem’. This is then followed by
careful examinations of the implications of market imperfection on prices for final goods and services. The
intent here is to provide a systematic and comprehensive examination: (i) how, in general, monopoly
‘power’ causes price distortion and in so doing may lead to losses in social welfare, (ii) alternative public
policy measures that can be used to correct price distortion that are caused by monopoly power, and (ii)
show the applications of game theoretic models to understand the strategic decision making behaviors of
oligopolistic firms. Finally, time permitting an attempt will be made to shed light on the implications of
markets with asymmetric information.
This course assumes that students have taken a course in calculus. Prerequisites: Eco 105 or 101
and Eco 205 or Math 112.

Part II, the theory of consumer choice, deals with every day decisions a rational and wellinformed consumer makes, such as on how much of her/his monthly income to spend for buying food or
other consumption goods and services; how much time to spend working or relaxing; and how much to
save. These decisions, as implied by the above diagram, are done after careful consideration of the
preference function, budget constraint and utility maximizing behavior of the individual consumer. As

implied by the entries in the last box of the above diagram, it is also out of this intellectual exercises that
generalized theories of consumer demand for final goods and services and supply for a factor of
production, such as labor are derived.

Part III, the theory of the firm, deals with how a business entity with a singular objective to
maximize profit makes decisions, such as on how many units of output to produce and workers or some
other factor of productions to use in its daily business dealings. This is done, as indicated in the diagram
above after careful considerations of the firm’s technological options (which determines the structure of the
cost of production), budget constraint and profit maximizing behavior. This basic theory of the firm is the
cornerstone for the neoclassical theories of supply for final goods and services and the demand for factors of
production (see the last box in the above diagram).

PART IV
PRICING AND OUTPUT DECISION UNDER IMPERFECTLY COMPETITIVE
MARKET STRUCTURES
Parts II and III together thoroughly and systematically examined the neoclassical theories of
demand and supply (for both the product and factor markets). This investigation was done assuming a
perfectly competitive market structure. Part IV, which in some respect is an extension of Parts II and III,
deals with two pertinent issues. It starts with a comprehensive evaluation of the performance (i.e.,
economic efficiency) of a competitive market system in the long-run—the so-called Adam Smith’s Invisible
Hand Theorem. In this case, economic efficiency entails the maximization of aggregate consumer and
producer surplus. The second issue deals with the effects of market imperfections on the pricing, production
and employment decisions of a firm and what these outcomes might suggest to the efficiency by which
resources allocated for society at large. Furthermore, time permitting, the discussion in Part IV, will
include an overview of a very important microeconomics topic; namely, asymmetric information – market
situations where some parties know more than others.
1. Evaluating the performance competitive markets: The best of all worlds!
a) A revisit of the long-run equilibrium condition of a competitive industry
b) The equivalence of achieving maximum net social surplus and the long-run equilibrium
