NATIONAL OPEN UNIVERSITY OF NIGERIA COURSE CODE AEM 751 COURSE TITLE: MICROECONOMICS Department of Agricultural Economics and Extension National Open University of Nigeria, Kaduna UNIT ONE: SCOPE ECONOMICS Table of contents 1.0 Introduction 2.0 Objectives 3.1 Definition of Economics 3.2 Resources 3.3 Scarcity 3.4 Choice and opportunity cost 3.5 Basic economic problems 4.0 conclusion 5.0 summary 6.0 tutor – marked assignment 7.0 references and further readings 1.0 INTRODUCTION Most of you must have acquired some basic knowledge of economics before this stage of study. In this introductory unit, we shall be investigating the scope of economics in terms of how economics play the important role of preferring solution to the problem of society. It has been realized that resources are limited and human wants. Economist therefore focus on the problem of making the best use of resources available to satisfy these wants. Since there are many alternative things we can do with our resources, choice has to be made as to which to have per time. This unit will take you through the concept of wants, scarcity and opportunity cost. The unit will also consider some basic problems that economist attempt to deduce solution. 2.0 OBJECTIVE It is expected that after you must have gone through this course, you should be able to: 1. Define economics and make basic distinction between macroeconomics and microeconomics. 2. Define resources 3. Identify the various types of productive resources 4. Describe the relationship between scarcity and choice. 5. Explain the concept of opportunity cost 6. -
General Equilibrium Theory and Welfare Economics: Theory Vs
General Equilibrium Theory and Welfare Economics: Theory vs. Praxis The development of economic thought after World War II has been nothing short of protean in character, yet it can be traced, at least in part, by following a number of lines resulting from attempts to flesh-out, resolve, or simply come to terms with general equilibrium theory. As you might recall from subunit 4.1.2, general equilibrium theory came about in the latter half of the 19th century explicitly in the form of Leon Walras’s 1874 work, Elements of Pure Economics, and subsequently with the addition of graphical representation in his 1892 paper “Geometrical Theory of the Determination of Prices”: It follows from the nature of the [supply and demand] curves, that we shall obtain the provisional current price of (B) by raising it in case of a surplus of effective demand over effective supply, and lowering it, on the contrary, in case of a surplus of effective supply over effective demand. Passing then to the determination of the current price of (C), then to the current price of (D) ..., we obtain them by the same means. It is quite true that, in determining the price of (C), we may destroy the equilibrium in respect to (B); that, in determining the price of (D), we may destroy the equilibrium in respect to (B), and in respect to (C), and so on. But as the determinations of the prices of (C), (D) ... in respect to the demand and supply of (B), will result in a contrary way, we shall always be nearer the equilibrium at the second trial than at the first. -
A Hayekian Theory of Social Justice
A HAYEKIAN THEORY OF SOCIAL JUSTICE Samuel Taylor Morison* As Justice gives every Man a Title to the product of his honest Industry, and the fair Acquisitions of his Ancestors descended to him; so Charity gives every Man a Title to so much of another’s Plenty, as will keep him from ex- tream want, where he has no means to subsist otherwise. – John Locke1 I. Introduction The purpose of this essay is to critically examine Friedrich Hayek’s broadside against the conceptual intelligibility of the theory of social or distributive justice. This theme first appears in Hayek’s work in his famous political tract, The Road to Serfdom (1944), and later in The Constitution of Liberty (1960), but he developed the argument at greatest length in his major work in political philosophy, the trilogy entitled Law, Legis- lation, and Liberty (1973-79). Given that Hayek subtitled the second volume of this work The Mirage of Social Justice,2 it might seem counterintuitive or perhaps even ab- surd to suggest the existence of a genuinely Hayekian theory of social justice. Not- withstanding the rhetorical tenor of some of his remarks, however, Hayek’s actual con- clusions are characteristically even-tempered, which, I shall argue, leaves open the possibility of a revisionist account of the matter. As Hayek understands the term, “social justice” usually refers to the inten- tional doling out of economic rewards by the government, “some pattern of remunera- tion based on the assessment of the performance or the needs of different individuals * Attorney-Advisor, Office of the Pardon Attorney, United States Department of Justice, Washington, D.C.; e- mail: [email protected]. -

The more complex the civilization the greater the number of public goods that needed to be provided. Ours is far and away the most complex civilization humanity has ever developed. So its need for public goods – and goods with public goods aspects, such as education and health – is extraordinarily large. The institutions that have historically provided public goods are states. But it is unclear whether today’s states can – or will be allowed to – provide the goods we now demand.”1 -Martin Wolf, Financial Times 1 Martin Wolf, “The World’s Hunger for Public Goods”, Financial Times, January 24, 2012. 2 PUBLIC GOODS IN EVERYDAY LIFE TABLE OF CONTENTS 1.

On Welfare Economics in the Principles Course
THE JOURNAL OF ECONOMIC EDUCATION , VOL. , NO. , – http://dx.doi.org/./.. CONTENT ARTICLES IN ECONOMICS On welfare economics in the principles course N. Gregory Mankiw Department of Economics, Harvard University, Cambridge, MA, USA ImuchenjoyedreadingthesearticlesbySteveSchmidtandJonathanB.Wightonthenormativeunder- pinningsofhowweteachintroductoryeconomics.Ihavelongbelievedthatteachingthefundamentalsof economics to the next generation of voters is among the highest callings of our profession. It is therefore useful to regularly reflect on whether we are doing it well and how we might do it better. I agree with many of the substantive points raised in the articles, although I think that the current crop of textbooks (including my own) do a better job than Schmidt and Wight sometimes give them credit for. Rather than quibble with details, however, let me lay out five of the main lessons that I emphasize as Iteachthismaterial: (1) Efficiency is a useful lens through which to view outcomes. Understanding market success and market failure is a central feature of my course, especially in the microeconomics half. Adam Smith’s invisible hand is best understood as the proposition that the equilibrium of supply and demand maximizes the sum of producer and consumer surplus. The market failures that arise from externalities or monopoly power are best understood as the departure of the unregulated outcome from the surplus-maximizing allocation of resources. (2) Efficiency is not the only goal of policy.Whenintroducingthenotionofefficiency,Imakeclear that policymakers have other objectives as well. In chapter 1 of my text (Mankiw 2015, 12),I wrote, “Even when the invisible hand yields efficient outcomes, it can nonetheless leave sizable disparities in economic well-being. … The invisible hand does not ensure that everyone has suf- ficient food, decent clothing, and adequate healthcare. -
Public Goods for Economic Development
Printed in Austria Sales No. E.08.II.B36 V.08-57150—November 2008—1,000 ISBN 978-92-1-106444-5 Public goods for economic development PUBLIC GOODS FOR ECONOMIC DEVELOPMENT FOR ECONOMIC GOODS PUBLIC This publication addresses factors that promote or inhibit successful provision of the four key international public goods: fi nancial stability, international trade regime, international diffusion of technological knowledge and global environment. Each of these public goods presents global challenges and potential remedies to promote economic development. Without these goods, developing countries are unable to compete, prosper or attract capital from abroad. The undersupply of these goods may affect prospects for economic development, threatening global economic stability, peace and prosperity. The need for public goods provision is also recognized by the Millennium Development Goals, internationally agreed goals and targets for knowledge, health, governance and environmental public goods. Because of the characteristics of public goods, leaving their provision to market forces will result in their under provision with respect to socially desirable levels. Coordinated social actions are therefore necessary to mobilize collective response in line with socially desirable objectives and with areas of comparative advantage and value added. International public goods for development will grow in importance over the coming decades as globalization intensifi es. Corrective policies hinge on the goods’ properties. There is no single prescription; rather, different kinds of international public goods require different kinds of policies and institutional arrangements. The Report addresses the nature of these policies and institutions using the modern principles of collective action.

An economy exists because of two basic facts. Firstly human wants for goods and services are unlimited and secondly productive resources with which to produce goods and services are scarce. In other words, we have the problem of allocating scarce resource so as to achieve the greatest possible satisfaction of wants. -
Assessing the Comparative Performance of Competition
Assessing the comparative performance of competition authorities Khemla Prishnee Armoogum Thesis submitted for the degree of Doctor of Philosophy University of East Anglia School of Economics July 2016 This copy of the thesis has been supplied on condition that anyone who consults it is understood to recognise that its copyright rests with the author and that use of any information derived there from must be in accordance with current UK Copyright Law. In addition, any quotation or extract must include full attribution. Abstract Finding an effective way of assessing the performance of a competition authority is an objective that recently has been widely debated by academics and practitioners. Although several methods of evaluation exist, the issue that still remains unsolved is how the assessment could be done systematically. This thesis consists of one descriptive, and four substantive chapters, the substantive chapters (3-6) includes one theoretical and three empirical, all centred on the assessment of competition law and policy enforcement. The first empirical chapter (3) studies the determinants of the reputation of a competition authority (used as a proxy for performance). In the theoretical chapter (4), a model is developed to understand how an age profile of the number of cartels detected by a competition authority can reflect the combined effects of increasing detection efficiency and greater success of deterrence over time. The second empirical chapter (5) builds on the theoretical model and studies the age profile of cartel cases detected across time and between different competition authorities. Finally, the last chapter (6) empirically examines the possible interactions between the different types of competition cases (mergers, cartels, abuse) in the presence of a competition authority which is budget constrained, and therefore must choose how to allocate its resources between these different areas. -

Abstract This article considers aggregate price determination related to the neutrality of money. When the true cost of living can be defined as the function of prices in the overlapping generations (OLG) model, the marginal cost of a firm solely depends on the current and future prices. Further, the sequence of equilibrium price becomes independent of the quantity of money. Hence, money becomes non-neutral. However, when people hold the extraneous be- lief that prices proportionately increase with money, the belief also becomes self-fulfilling so far as the increment of money and the true cost of living are low enough to guarantee full employment. -
Defining Economics in the Twenty First Century
Modern Economy, 2012, 3, 597-607 http://dx.doi.org/10.4236/me.2012.35079 Published Online September 2012 (http://www.SciRP.org/journal/me) Defining Economics in the Twenty First Century Bhekuzulu Khumalo Private Researcher, Toronto, Canada Email: [email protected] Received June 4, 2012; revised July 2, 2012; accepted July 10, 2012 ABSTRACT Economics as a subject matter has been given a variety of definitions over the last 200 years, however all the definitions have a similar concept that they lean towards, a general principle one can say. The definitions are not wrong, this paper does not seek to prove that they are wrong, but only to show they where right for their time, a subject matter like eco- nomics, though studied over the centuries only formally became a discipline in its own right in the last two centuries, and as such is fairly young and as we know more there perhaps is a time to seek a definition for economics for the twenty first century. This paper seeks to give such a definition in light of the increased understanding of economics or at the least we have access to greater information concerning the discipline economics than say Adam Smith, Alfred Mar- shall or Hayek. Take the definition by Samuelson, “Economics is the study of how societies use scarce resources to produce valuable commodities and distribute them among different people”, though correct, is the definition sufficient for the twenty first century and beyond, that is all this paper seeks to answer, for it is the definition of a discipline that guides the readers thoughts. -
Antitrust Policy As Corporate Welfare
ANTITRUST REFORM PROJECT ANTITRUST POLICY AS CORPORATE WELFARE CLYDE WAYNE CREWS JR. July 1997 ISSN# 1085-9049 ANTITRUST POLICY AS CORPORATE WELFARE Clyde Wayne Crews Jr. EXECUTIVE SUMMARY Political party reformers promised to roll back the regulatory states excesses during the 1994 and 1996 election cycles. While broad-based reform targeting counterproductive environmental and risk regulation didnt occur, a recognition persists that regulations often go too far. However, there has never been a fundamental rethinking of antitrust regulation. Despite the growing awareness of regulatory failure, antitrust, which purports to protect consumers by policing monopoly power, stands nearly unscathed as a model of public spirited regulation of business, an essential tool for protecting consumers from monopoly exploitation. Indeed, antitrust is usually believed essential to protecting the free enterprise system. This benign reputation of antitrust is undeserved and harmful. Policymakers of both parties especially those who believe antitrust promotes consumer welfare should rethink their allegiance. Many commentators have noted that antitrusts rhetoric of protecting the public doesnt fit with its actual tendency to penalize beneficial and efficient practices. Few today defend the actual performance record of antitrust. Defenders of antitrust still tend to think that applying better economics and hiring better judges will improve antitrust policy outcomes. Antitrust invites the special-interest exploitation of the public and successful businesses by legally facilitating the hobbling of competitors and offering the incentive of treble damage awards. There has never been an official acknowledgment that antitrust is fundamentally flawed and contrary to consumer interests. No part of antitrust law has been repealed. Today, antitrust is enjoying a higher profile in actions such as those against Wal-Mart, Microsoft, and the proposed Staples/Office Depot merger.
