Shopping Externalities and Self-Fulfilling Unemployment Fluctuations Greg Kaplan and Guido Menzio NBER Working Paper No. 18777 February 2013, Revised October 2013 JEL No. D11,D21,D43,E32 ABSTRACT We propose a novel theory of self-fulfilling unemployment fluctuations. According to this theory, a firm hiring an additional worker creates positive external effects on other firms, as a worker has more income to spend and less time to search for low prices when he is employed than when he is unemployed. -
Managerial Economics Unit 6: Oligopoly
Managerial Economics Unit 6: Oligopoly Rudolf Winter-Ebmer Johannes Kepler University Linz Summer Term 2019 Managerial Economics: Unit 6 - Oligopoly1 / 45 OBJECTIVES Explain how managers of firms that operate in an oligopoly market can use strategic decision-making to maintain relatively high profits Understand how the reactions of market rivals influence the effectiveness of decisions in an oligopoly market Managerial Economics: Unit 6 - Oligopoly2 / 45 Oligopoly A market with a small number of firms (usually big) Oligopolists \know" each other Characterized by interdependence and the need for managers to explicitly consider the reactions of rivals Protected by barriers to entry that result from government, economies of scale, or control of strategically important resources Managerial Economics: Unit 6 - Oligopoly3 / 45 Strategic interaction Actions of one firm will trigger re-actions of others Oligopolist must take these possible re-actions into account before deciding on an action Therefore, no single, unified model of oligopoly exists I Cartel I Price leadership I Bertrand competition I Cournot competition Managerial Economics: Unit 6 - Oligopoly4 / 45 COOPERATIVE BEHAVIOR: Cartel Cartel: A collusive arrangement made openly and formally I Cartels, and collusion in general, are illegal in the US and EU. I Cartels maximize profit by restricting the output of member firms to a level that the marginal cost of production of every firm in the cartel is equal to the market's marginal revenue and then charging the market-clearing price. F Behave like a monopoly I The need to allocate output among member firms results in an incentive for the firms to cheat by overproducing and thereby increase profit. -

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.

Learning Externalities and Economic Growth
Learning Externalities and Economic Growth Alejandro M. Rodriguez∗ August 2004 ∗I would like to thank Profesor Robert E. Lucas for motivating me to write this paper and for his helpful comments. Profesor Alvarez also provided some useful insights. Please send comments to [email protected]. All errors are mine. ABSTRACT It is a well known fact that not all countries develop at the same time. The industrial revolution began over 200 years ago in England and has been spreading over the world ever since. In their paper Barriers to Riches, Parente and Prescott notice that countries that enter the industrial stage later on grow faster than what the early starters did. I present a simple model with learning externalities that generates this kind of behavior. I follow Lucas (1998) and solve the optimization problem of the representative agent under the assumption that the external effect is given by the world leader’s human capital. 70 60 50 40 30 20 Number of years to double income 10 0 1820 1840 1860 1880 1900 1920 1940 1960 1980 Year income reached 2,000 (1990 U.S. $) Fig. 1. Growth patterns from Parente and Prescott 1. Introduction In Barriers to Riches, Parente and Prescott observe that ”Countries reaching a given level of income at a later date typically double that level in a shorter time ” To support this conclusion they present Figure 1 Figure 1 shows the year in which a country reached the per capita income level of 2,000 of 1990 U.S. dollars and the number of years it took that country to double its per capita income to 4,000 of 1990 U.S. -

NBER WORKING PAPER SERIES THE DEADWEIGHT LOSS FROM "NONNEUTRAL" CAPITAL INCOME TAXATION Alan J. Auerbach Working Paper No. 2510 NATIONAL BUREAU OF ECONOMIC RESEARCH 1050 Massachusetts Avenue Cambridge, MA 02138 February 1988 I am grateful to the National Science Foundation for financial support (grant #SES— 8617495), to Kevin Hassett for excellent research assistance, and to Jim Hines, Larry Kotlikoff and participants in seminars at Columbia, NBER, Penn and Western Ontario for connnents on earlier drafts. The research reported here is part of the NBERs research program in Taxation. Any opinions expressed are those of the author and not those of the National Bureau of Economic Research, Support from The Lynde and Harry Bradley Foundation is gratefully acknowledged. NBER Working Paper #2510 The Deadweight Loss froni "Nonneutral" Capital Income Taxation ABSTRACT This paper develops an overlapping generations general equilibrium growth model with an explicit characterization of the role of capital goods in the evaluate and production process. The model is rich enough in structure to measure simultaneously the different distortions associated with capital income taxation (across sectors, across assets and across time) yet simple enough to yield intuitive analytical results as well. The main result is that uniform capital income taxation is almost certainly suboptimal, theoretically, but that empirically, optimal deviations from uniform taxation are inconsequential. We also find that though the gains from a move to uniform taxation are not large in absolute magnitude these of gains would be offset only by an overall rise in capital income tax rates several percentage points. A separate contribution of the paper is the development of a technique for distinguishing intergenerational transfers from efficiency gains in analyzing the effects of policy changes on long—run welfare. -
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.

Total Cost and Profit
4/22/2016 Total Cost and Profit Gina Rablau Gina Rablau - Total Cost and Profit A Mini Project for Module 1 Project Description This project demonstrates the following concepts in integral calculus: Indefinite integrals. Project Description Use integration to find total cost functions from information involving marginal cost (that is, the rate of change of cost) for a commodity. Use integration to derive profit functions from the marginal revenue functions. Optimize profit, given information regarding marginal cost and marginal revenue functions. The marginal cost for a commodity is MC = C′(x), where C(x) is the total cost function. Thus if we have the marginal cost function, we can integrate to find the total cost. That is, C(x) = Ȅ ͇̽ ͬ͘ . The marginal revenue for a commodity is MR = R′(x), where R(x) is the total revenue function. If, for example, the marginal cost is MC = 1.01(x + 190) 0.01 and MR = ( /1 2x +1)+ 2 , where x is the number of thousands of units and both revenue and cost are in thousands of dollars. Suppose further that fixed costs are $100,236 and that production is limited to at most 180 thousand units. C(x) = ∫ MC dx = ∫1.01(x + 190) 0.01 dx = (x + 190 ) 01.1 + K 1 Gina Rablau Now, we know that the total revenue is 0 if no items are produced, but the total cost may not be 0 if nothing is produced. The fixed costs accrue whether goods are produced or not. Thus the value for the constant of integration depends on the fixed costs FC of production. -
Product Differentiation
Product differentiation Industrial Organization Bernard Caillaud Master APE - Paris School of Economics September 22, 2016 Bernard Caillaud Product differentiation Motivation The Bertrand paradox relies on the fact buyers choose the cheap- est firm, even for very small price differences. In practice, some buyers may continue to buy from the most expensive firms because they have an intrinsic preference for the product sold by that firm: Notion of differentiation. Indeed, assuming an homogeneous product is not realistic: rarely exist two identical goods in this sense For objective reasons: products differ in their physical char- acteristics, in their design, ... For subjective reasons: even when physical differences are hard to see for consumers, branding may well make two prod- ucts appear differently in the consumers' eyes Bernard Caillaud Product differentiation Motivation Differentiation among products is above all a property of con- sumers' preferences: Taste for diversity Heterogeneity of consumers' taste But it has major consequences in terms of imperfectly competi- tive behavior: so, the analysis of differentiation allows for a richer discussion and comparison of price competition models vs quan- tity competition models. Also related to the practical question (for competition authori- ties) of market definition: set of goods highly substitutable among themselves and poorly substitutable with goods outside this set Bernard Caillaud Product differentiation Motivation Firms have in general an incentive to affect the degree of differ- entiation of their products compared to rivals'. Hence, differen- tiation is related to other aspects of firms’ strategies. Choice of products: firms choose how to differentiate from rivals, this impacts the type of products that they choose to offer and the diversity of products that consumers face. -
