how to best ensure remuneration for creators in the market for music copyright and its alternatives the focus of this essay is to examine the market for copyrighted works with a particular emphasis on the sound recording market this market is currently in a state of flux some would say disarray due to the ability of the internet to lower transmission costs for both authorized and unauthorized copies with the latter being at this time far more prevalent in this essay we discuss the intent of copyright the role of copying and file sharing and some alternative production consumption schemes meant to strengthen or to replace copyright

implications of energy subsidy reform in india abstract this paper analyses welfare impact of energy subsidy reform in india based on the data from 1970 71 to 2014 15 to this end auto regressive distributed lag ardl model and error correction model ecm have been estimated to quantify the short run and long run price and the income elasticity of various energy products the results show that the price elasticity of demand for all fossil fuels is low but the respective income elasticity is higher therefore an increase in the general price level caused by the subsidy reform will lead to the erosion of real income and will have related welfare implications in india the results also reveal that energy expenditure will obviously increase and hence energy consumption will decline depending upon the extent of the withdrawal of subsidy therefore policy makers in india while undertaking further reforms must ensure that the subsidy reaches to those who truly deserve so that the socioeconomic casualty of reforms can be minimized along with achieving fiscal goals

lessons from strange cases democracy development and the resource curse in the u s states the work linking natural resource wealth to authoritarianism and under development suffers from several shortcomings in this article the authors outline those shortcomings and address them in a new empirical setting using a new data set for the u s states spanning 73 years and case studies of texas and louisiana the authors are able to more carefully examine both the diachronic nature and comparative legs of the resource curse hypothesis than previous research has they provide evidence that natural resource dependence contributes to slower economic growth poorer developmental performance and less competitive politics using this empirical setting they also begin parsing the mechanisms that might explain the negative association between resource wealth and political and economic development they draw implications from intranational findings for resource abundant countries across the world and suggest directions for future cross national and cross state work

demand systems with nonstationary prices relative prices are nonstationary and standard root t inference is invalid for demand systems but demand systems are nonlinear functions of relative prices and standard methods for dealing with nonstationarity in linear models cannot be used demand system residuals are also frequently found to be highly persistent further complicating estimation and inference we propose a variant of the translog demand system the ntlog and an associated estimator that can be applied in the presence of nonstationary prices with possibly nonstationary errors the errors in the ntlog can be interpreted as random utility parameters the estimates have classical root t limiting distributions we also propose an explanation for the observed nonstationarity of aggregate demand errors based on aggregation of consumers with heterogeneous preferences in a slowly changing population estimates using u s data are provided

the case against intellectual property according to a common argument the presence of strong intellectualproperty rights spurs innovation which leads to higher economic growthand increasing benefits for all the argument seems coherent theestablishment of secure property rights is a fundamental pillar of a wellfunctioning market economy no economic agent exercises productiveeffort without the certainty of controlling its fruits what is true forphysical effort must be true for the intellectual one if strong propertyrights provide good incentives for the production of potatoes they mustalso provide good incentives for the production of ideas why then do we argue a case against intellectual property are wearguing that while stealing potatoes is bad stealing ideas is good weare not economic efficiency and common sense argue that ideasshould be protected and available for sale just like any other commodity but intellectual property has come to mean not only the right to ownand sell ideas but also the right to regulate their use this creates asocially inefficient monopoly and what is commonly called intellectualproperty might be better called intellectual monopoly when you buy apotato you can eat it throw it away plant it or make it into a sculpture current law allows producers of a cds and books to take this freedomaway from you when you buy a potato you can use the idea of a potatoembodied in it to make better potatoes or to invent french fries currentlaw allows producers of computer software or medical drugs to take thisfreedom away from you it is against this distorted extension ofintellectual property rights that we argue it is a long jump from the assertion that inventors deserve the fruits oftheir efforts to the conclusion that current patent and copyrightprotection are the best way of providing such reward statements such

the origins and development of the northeast asian political economy industrial sectors product cycles and political consequences theories of the product cycle hegemony and the world system are used to analyze the creation and development of the northeast asian political economy in this century japan south korea and taiwan have each developed in a particular relationship with the others the three taken together form a hierarchical constantly interacting political economic unit during the period of colonial rule japan was unique in building an imperial economic unit marked by a strong role for the state whether in tokyo or taipei by a tight integral unking of all three nations into a communications and transport network running toward the metropole and by a strategy of both using the colonies for agricultural surpluses and then locating industries there after 1945 a diffuse american hegemony replaced japan s unilateral system but elements of the prewar model have survived strong states direct economic development in south korea and taiwan here termed bureaucratic authoritarian industrializing regimes both countries are receptacles for japan s declining industries and both countries develop in tandem if in competition with each other the most recent export led competition has seen taiwan succeed where south korea has temporarily failed leaving seoul in an export led trap burdened with rapidly increasing external debt taiwan furthermore has industrialized relatively free of social disruption whereas korean society resisted its transformation at japanese hands and remains more rebellious today there can be one japan and one taiwan but not two or many of either in the world economy

changing comparative advantage and the changing composition of asian exports apid economic growth in several asian economies particularly those from east and southeast asia and subsequently in china and south asia has led to rapid structural transformation in these economies if one takes a historical perspective it was in accordance with what kuznets 1966 and chenery and syrquin 1975 posited in a growing economy the decline of the agricultural sector has generally been accompanied by strong expansion of the manufacturing and or services sector transforming economic structure has had a direct bearing on the trade structure of the economy looking back three decades one finds that in several asian economies the structural transformation has been more or less fundamental pari passu these economies have experienced a dynamic process of changing comparative advantage this entailed a rapid growth in their exports of manufactures as well as a changing structure of manufactured exports in what follows we will evaluate the process of transformation of economic structures and changes in the manufacturing sector in the asian economies followed by changes in comparative advantage resulting in higher product sophistication of exports with the passage of time

patenting in the shadow of competitors this article empirically examines the patenting behavior of new biotechnology firms that have different litigation costs i show that firms with high litigation costs are less likely to patent in subclasses with many other awards particularly those of firms with low litigation costs this pattern is consistent with the literature on costly litigation which suggests that firms that have high litigation costs will take greater precautions to avoid litigation these results are robust to a variety of control variables and modifications that seek to test alternative explanations

do patents over compensate innovators is the current level of patent protection too high or too low to address this issue this paper reformulates the theoretical analysis of the optimal level of patent protection to take into account the empirical findings of the innovation production function literature this literature finds a strong relationship between r d spending and inventions and estimates an elasticity of the supply of inventions of 0 5 or more the paper then assesses the current level of patent protection exploiting estimates of the private and social returns to r d taken from the empirical literature and other available sources although more research is needed for a more precise assessment the evidence available suggests that patents do not over compensate innovators vincenzo denicolo

the composition of u s east asia trade and changing comparative advantage abstract this paper examines the composition of trade between the united states and eight asian pacific economies from 1962 to 1992 analysis of the time series pattern of individual commodities at the sitc four digit level reveals economically significant changes in the pattern of trade reflecting changing comparative advantage based on changing factor proportions technology transfer and product cycles the composition of the eight bilateral trade relationships shows both increasing specialization over time and a sequence from japan to the four tigers korea taiwan singapore and hong kong and then to the remaining three east asian economies malaysia indonesia and thailand

estimating a cointegrating demand system abstract the set of variables in a time series demand model in the form of the almost ideal demand system are found to be i 1 with the demand equations forming a cointegrating system the parameters of the cointegrating equations are estimated and tested using a triangular error correction procedure the null hypothesis of homogeneity with respect to prices and nominal income in the system cannot be rejected

the government financial system and large private enterprises in the economic development of south korea abstract the paper investigates the main characteristics of the government business relationship in south korea in the past three decades to find out how it may have contributed to south korea s economic development it proposes that the government and large private enterprises in south korea should be viewed as constituting an internal organization namely a quasi internal organization as such extensive intervention by the government with south korea s financial system can be viewed as an internal capital market and consequently it could have led to a more efficient allocation of credit than possible in a free market financial system it also argues that the quasi internal organization has made it possible for the government to efficiently implement its developmental policies it is however pointed out that for the quasi internal organization to be successful in accelerating the pace of economic development the country must have a political leadership committed to the goal of economic development and must adopt an outward oriented development policy

evaluation of the subjective probabilities of survival in the health and retirement study in the health and retirement study respondents were asked about the chances they would live to 75 or to 85 we analyze these responses to determine if they behave like probabilities of survival if their averages are close to average probabilities in the population and if they have correlations with other variables that are similar to correlations with actual mortality outcomes we find that generally they do behave like probabilities and that they do aggregate to population probabilities most remarkable however is that they covary with other variables in the same way actual outcomes vary with the variables for example respondents with higher socioeconomic status give higher probabilities of survival whereas respondents who smoke give lower probabilities we conclude that these measures of subjective probabilities have great potential use in models of intertemporal decision making under uncertainty

firm size and r d intensity a re examination using data from the federal trade commission s line of business program and survey measures of technological opportunity and appropriability conditions this paper finds that overall firm size has a very small statistically insignificant effect on business unit r d intensity when either fixed industry effects or measured industry characteristics are taken into account business unit size has no effect on the r d intensity of business units that perform r d but it affects the probability of conducting r d business unit and firm size jointly explain less than one per cent of the variance in r d industry effects explain nearly half the variance two sets of well known hypotheses are associated with the later work of joseph schumpeter the first concerns the effects of market concentration on research and development investment and on innovative performance the second bears on the effects of firm size on r d and innovation in a recent paper levin cohen and mowery 1985 we re examined the first set of hypotheses simple regressions at the line of business level replicated the established findings that both r d intensity and innovative performance first increase and then decrease as industrial concentration rises the effect of concentration however was sharply attenuated when we controlled for interindustry differences in technological opportunity and in the appropriability of returns from new technology our results suggested that it is probably unwarranted to conclude that market concentration favors r d investment and innovation in this paper we investigate the schumpeterian hypothesis that large size is conducive to r d investment this relationship has been studied at least as intensively as the link between concentration and r d but our approach is novel in two respects first using data collected by the federal trade

are nonconvexities important for understanding growth everyday experience and a simple logical argument show that nonconvexities are essential for understanding growth compared to previous statements of this well known argument the presentation here places more emphasis on the distinction between two of the fundamental attributes of any economic good rivalry and excludability it also emphasizes the difference between public goods and the technological advances that are fundamental to economic growth like public goods technological advances are rionrival goods hence they are inextricably linked to nonconvexities but in contrast to public goods which are nonexcludable technological advances generate benefits that are at least partially excludable hence innovations in the technology are for the most part privately provided this means that nonconvexities are relevant for goods that trade in private markets consequently an equilibrium with price taking in all markets cannot be sustained concluding remarks describe some of the recent equilibrium growth models that do not rely on price taking and highlight some of the implications of these models this abstract was borrowed from another version of this item

towards a dynamic schumpeterian welfare economics knowledge plays an increasingly important role in shaping the dynamics of an economy a static paretian welfare economics is therefore inadequate and needs to be supplemented by a dynamic schumpeterian welfare theory a dynamic welfare economics acknowledges the role of knowledge and communication as knowledge develops cumulatively in a social environment knowledge may not be readily diffused or exchanged different costs of communication need to be considered each affecting the creation of new knowledge recent developments in intellectual property right ipr law are evaluated to determine the extent to which they affect communication costs and thus future economic welfare

the quest for evidence on the economic effects of copyright law the requirement by the uk government for evidence based policy has recently been applied to copyright law in the context of i hargreaves s report digital opportunity review of intellectual property and growth newport intellectual property office 2011 in this article i focus on data that have been used to make the case for copyright with government but it is argued that this does not produce the evidence that is needed for policy purposes the problem facing economists in providing such evidence is discussed in detail in connection with hargreaves proposal for a digital copyright exchange copyright oxford university press

global warming and endogenous technological change revisiting the green paradox one of the most pressing policy challenges facing the world today concerns how to mitigate global warming while improving people s well being the green paradox argues that increasing taxes on co2 emissions exacerbates global warming in the present because firms have the incentive to bring forward the extraction and sale of fossil fuels this paper shows that whenever technological progress allows the extraction costs of fossil fuels to be reduced over time and a positive r d subsidy is paid a growing tax on co2 emissions reveals a welfare maximizing policy

limits of state strength toward an institutionalist view of economic development nomic development attempted to explain why growth did not occur occurred slowly or occurred in a distorted dependent form the impressive economic performances of the east asian newly industrialized countries nics have changed this many noneconomists as well as some economists are now focusing on the political bases of development rather than underdevelopment there are differences among these analysts some distance themselves from neoclassical economics by emphasizing the importance of getting the prices wrong others acknowledge the utility of market conforming policies but common to recent studies of nics is the belief that growthpromoting economic policies require certain types of domestic political institutions analysts have emphasized the utility of strong states in this regard 2 through an analysis of efforts to promote local auto manufacturing in southeast as well as east asia this article argues for an institutionalist approach to development that goes beyond statism the resolution of collective action problems is central to statist writings development requires that private returns to individual activities be brought in line with the broader needs of national development 3 two factors are presumed to obstruct such harmonization in developing

stated and revealed heterogeneous risk preferences in educational choice abstract we develop a structural microeconometric model of educational choice with unobserved heterogeneity in risk aversion and estimate the model parameters using panel survey data we assess the credibility of the model by linking the estimated structural parameters of risk aversion to the self reported willingness to take risks which is directly elicited in the survey the risk aversion parameters revealed from educational choices decrease with the willingness to take risks stated by the survey respondents this indicates consistency between stated and revealed risk preferences we suggest that this method could be applied more generally to support or reject the joint validity of structural models and survey measures of preferences

defense burden and economic growth unraveling the taiwanese enigma indicate that all these models capture parts of the empirical reality but none can account for all the complexity of this reality indeed in some crucial respects each of the models based as they have been primarily on intercountry comparisons is contradicted by the taiwanese time series i conclude that taiwan has not so much been able to avoid entirely the trade offs between defense and growth as to relax these trade offs the reasons contributing to this relaxation tend to set the taiwanese experience apart from the experiences of most other countries

a comparative analysis of the use of information inputs in the manufacturing sectors of korea and japan abstract the paper examines the use of two information inputs information labor and purchased information services in korean and japanese manufacturing sectors in 1980 marginal products and substitution elasticities are calculated from translog production function estimates for the average manufacturing sector both inputs seem to be relatively more underused in korea second the elasticity estimates suggest several hypotheses about the growth of private bureaucracies in the two economies the results are unlikely to apply to other economies which have not yet attained an advanced industrial structure a simplistic stages theory of economic development based on the growth of the information labor force is rejected

the logic of appropriability from schumpeter to arrow to teece this note expounds the abstract fundamentals of the appropriability problem re assessing insights from three classic contributions those of schumpeter arrow and teece whereas the first two contributions were explicitly concerned with the implications of appropriability for society at large teece s main concern was with practical questions of business strategy and economic organization this note argues that his practical concerns notwithstanding teece contributed en passant but fundamentally to the clarification of basic questions that previous authors had addressed less comprehensively and less satisfactorily specifically his analysis of the innovator s access to complementary assets undertaken from a contracting perspective can be seen as filling a significant gap in the previous theoretical discussion of appropriability 2006 published by elsevier b v

rent seeking and innovation innovations and their adoption are the keys to growth and development innovations are less socially useful but more profitable for the innovator when they are adopted slowly and the innovator remains a monopolist for this reason rent seeking both public and private plays an important role in determining the social usefulness of innovations this paper examines the political economy of intellectual property analyzing the trade off between private and public rent seeking while it is true in principle that public rent seeking may be a substitute for private rent seeking it is not true that this results always either in less private rent seeking or in a welfare improvement when the public sector itself is selfish and behaves rationally we may experience the worst of public and private rent seeking together

quality change in price indexes price indexes provide the fundamental building blocks for measuring the general price level along with real incomes and real output but the most important single price index for the united states the cpi has been criticized as significantly underestimating the pace of quality change this paper sketches the issues involved in the measurement of quality change in price indexes it reviews the theory of quality change discusses how the bureau of labor statistics deals with quality change and provides examples of measurement issues in practice it concludes with a proposal to resolve the massive uncertainties in this area

trade as the engine of growth in developing countries revisited economic growth in developed countries since the mid 1970s the only way to keep the engine of ldc growth beating at a satisfactory rate so the argument goes is to turn to an alternative source of fuel this lewis argues lies in trade among the developing countries which he asserts can take up the slack left by mdcs more developed countries as mdcs slow down 1980 p 560 pessimism about demand for ldc exports in developed countries markets is a recurrent theme in the development literature also familiar is the approach taken by lewis to dismiss past successes of ldcs in world trade by declaring the alleged engine of past growth to be no longer operating satisfactorily the intellectual foundations of the import substitution strategy laid in the 1950s by prebisch myrdal and most importantly nurkse rested on similar grounds arguing that the demand for periphery countries exports in the 20th century is far weaker than it was in the 19th century trade was dismissed as an engine of growth a function nurkse alleged it had served in the 19th century the solution prescribed in the 1950s was to look inward in effect to scrap the trade engine altogether lewis remedy coming two decades later when most importsubstitution possibilities in many ldcs have been all but exhausted retains the trade engine but seeks an alternative source of fuel to drive it the classic critique by irving kravis 1970 of nurkse s thesis of trade as a faltering engine of growth showed that export expansion did not serve in the nineteenth century to differentiate successful from unsuccessful countries p 850 this followed from two findings first that successful 19th century countries showed few signs of export dominated growth second that unsuccessful periphery countries enjoyed export expansion in the second half of the 19th century of the same order of magnitude as the temperate regions of recent settlement this led kravis to conclude that a more warranted metaphor

waiting to imitate on the dynamic pricing of knowledge we study the problem of an inventor who brings to the market an innovation that can be legally imitated imitators may enter the market by imitating the innovation at a cost or by buying from the inventor the knowledge necessary to reproduce and use the invention the possibility of contracting dramatically affects the need for patent protection our results show that i imitators wait to enter the market and the inventor becomes a temporary monopolist ii the inventor sells knowledge through contracts that allow resale by the imitators and iii under certain conditions the inventor s payoff increases with the number of imitators

south korean and taiwanese development and the new institutional economics the publication of books by both alice amsden and robert wade provide an opportune moment to reflect on the study of east asian development after an initial surge of interest beginning in the 1970s the field has reached a plateau and scholars recently have cast a wide net in searching for ways to extend the field in assessing the state of the art regarding the economic development of the east asian newly industrialized countries nics this review will treat three themes first i will argue that the focus on states versus markets is becoming stale and that much of the scholarly interest lies in the politics behind the economics second i argue that political scientists have underexplored the historical origins of korean and taiwanese capitalism and that such attention promises to strengthen both theories and explanations of development third i argue that the international system has been more important in promoting development in east asia than accounts in the first wave have recognized the purpose of this review is to assess the field reveal

reflections of david teece s profiting from technological innovation abstract this paper builds on teece s 1986 paper to consider how appropriability conditions affect the ability of an industry and the economy as a whole to progress in particular it offers a careful discussion of the broader costs and benefits of patenting can too much appropriability actually work against the broader interests of society in fostering economic growth and technical advance in the market

aggregation without separability a generalized composite commodity theorem this paper provides general conditions for aggregating commodities without separable utility these conditions impose weaker and more empirically plausible restrictions on price movements than the currently existing alternative to separability the hicks leontief composite commodity theorem the idea is to allow departures from hicks leontief that take the form of well behaved error terms utility functions that permit generalized composite commodity aggregation include the aids model the translog all homothetic utility functions and any utility function when demands are aggregated to two groups of goods implications of empirical nonstationarity of relative prices for aggregation and demand estimation are considered copyright 1996 by american economic association

how much should society fuel the greed of innovators on the relations between appropriability opportunities and rates of innovation the paper attempts a critical assessment of both the theory and the empirical evidence on the role of appropriability and in particular of intellectual property rights iprs as incentives for technological innovation we start with a critical discussion of the standard justification of the attribution of ipr in terms of market failures in knowledge generation such an approach we argue misses important features of technological knowledge and also neglects the importance of non market institutions in the innovation process next we examine the recent changes in the ipr regimes and their influence upon both rates of patenting and underlying rates of innovation the evidence broadly suggests that first iprs are not the most important device apt to profit from innovation and second they have at best no impact or possibly even a negative impact on the underlying rates of innovation rather we argue technology and industry specific patterns of innovation are primarily driven by the opportunities associated with each technological paradigm conversely firm specific abilities to seize them and profit from innovation depend partly on adequacy of the strategic combinations identified by the taxonomy of teece d 1986 profiting from technological innovation implications for integration collaboration licensing and public policy research policy 15 285 305 and partly on idiosyncratic capabilities embodied in the various firms

the state and capitalist transformation in sub saharan africa a development model declining performance of the postcolonial african states suggest the inefficiency of centralization and or socialist strategy that currently dominates the region the solution however is not a return to the largely unrestrained liberal economic models of the 1960s such as import substitution industrialization or commodity export specialization whether from the left or right the inability of all three models to define precise development roles for africa state elites suggest their insensitivity to and inadequacy for the needs of these politically dynamic young states of africa an alternative model presented in this article would involve state elites in grass roots capitalist development the model fosters decentralization and economic development without sacrificing rule legitimization and national integration as equal objectives in many respects the model is an attempt to adapt to african realities the norms of embedded liberalism that properly describe current western liberalism

healthy food unhealthy food and obesity abstract we examine whether the latent behavioral mechanisms embedded in two price effects explanations of the obesity problem are operative our findings lend support to the hypothesis that falling food price is one likely cause of the obesity epidemic

the comparative homogeneity of the east asian nic exports of similar manufactures abstract the four tigers south korea hong kong taiwan and singapore serve as a model for successful export driven growth this paper examines the degree to which their export growth followed similar or divergent patterns in response to income and price changes differing responses were found in general to characterize export growth of these four countries however similar patterns were found to describe the exports of certain sophisticated research and development r d intensive products several explanations are posited and empirically examined

persistence of leadership in product innovation in a firm model of vertical product differentiation three distinct patterns of market shares emerge as an equilibrium outcome reflecting three distinct strategies in respect of timing of the introduction of new products the main novelty relative to the existing literature on vertical product differentiation lies in the incorporation of learning by doing this assumption generates stability of market share patterns over a sequence of product innovations copyright 1992 by blackwell publishing ltd

industry effects and appropriability measures in the stock market s valuation of r d and patents this paper examines the stock market s valuation of a firm s innovative activity we estimate the market s relative valuation of firms tangible and intangible assets focusing on knowledge capital in the form of accumulated stocks of r d and patents we tried to improve upon our estimates of the stock market s valuation of knowledge capital embodied in such stocks by bringing in measures of the appropriability environment facing a firm from the yale survey on industrial research and development the responses to survey questions about the effectiveness of patents as a mechanism for protecting the returns from innovation turn out to be of some use there is evidence of an interaction between industry level measures of the effectiveness of patents and the market s valuation of a firm s past r d and patenting performance as well as its current r d moves we find no evidence however that other appropriability mechanisms differ enough across industries to leave measurable traces in our data the structure of the yale survey makes it possible to estimate the sampling error in the appropriability measures derived from it this information was used by us in an errors in variables context but with little success in the absence of r d variables our estimates imply that a two standard deviation increase in our index of patent effectiveness would raise the value of a patent held by our average firm from 0 4 million to 1 0 million when r d variables are introduced into the equations the patents variables become insignificant r d expenditures are a better measure of input to the innovative function of firms than patents are of its output but we estimate that the same experiment would induce changes in q of between 10 and 27 percent for the average firm approximately doubling the market s valuation of this kind of capital this abstract was borrowed from another version of this item

investing to cooperate theory and experiment we study theoretically and in a lab experiment investment decisions in environments where property rights are absent in our setting a player chooses an investment level before interacting repeatedly with a given set of agents the investment stochastically affects the payoffs of the game in every subsequent period we show that more volatile returns make investment more difficult in the absence of legal protection and might force the investor to invest more to guarantee cooperation experimental results are broadly consistent with the theoretical findings

the economics of copyright the copyright industries such as music film software and publishing occupy a significant and growing share of economic activity current copyright law protects the creator for up to 70 years after their death significantly longer than patent protection 20 years after invention copyright law aims to balance the incentive to create new work against the costs associated with high prices and restricted access to this work this paper reviews the economic issues behind copyright and how these are challenged by changes in technology and market structure while economics provides a powerful conceptual framework for understanding the trade offs involved the paper argues that our empirical knowledge base is very weak much more empirical analysis is needed to understand the impacts of changes to copyright legislation without such analysis policy and legal debates will continue to be based largely on anecdote and rhetoric

perfect price discrimination with costless arbitrage abstract the ability of a monopoly seller to prevent resale is often presented as a necessary condition for first degree price discrimination in this paper we explore this claim and show that even with costless arbitrage markets price discrimination may continue to be both feasible and profit maximizing despite potential resale with finite numbers of consumers arbitrage markets may be thin in the sense that there can be too few low valuation consumers to supply high valuation consumers we examine both ex ante and ex post arbitrage markets and show how a monopoly can exploit potential thinness to profitably price discriminate in each case we present sufficient conditions for equilibrium price discrimination we note that the form of such discrimination depends on the nature of the arbitrage market and consider business strategies that a monopoly might adopt to exacerbate market thinness our results show how market depth and the effectiveness of arbitrage can be the key elements for price discrimination rather than the per se prevention of reselling

the assessment the twentieth century achievements failures lessons the past century saw unprecedented rises in life expectancy and living standards it also witnessed major structural changes the rise of big government and two globalizations yet the century s economic history was marred by policy and market failures resulting in a massive world wide depression frequent financial crises particularly in the developing world and several inflation spurts central planning set back development for one third of the world s population transition to the market economy was at best slow in some instances disastrous income distribution within countries changed little while productivity convergence between rich and poor economies was virtually absent policy making learnt some lessons from the 1930s experience particularly in the areas of macroeconomic management international cooperation and free trade dogmatic recipes however were often resorted to at home aided and abetted by the pretensions of the economics profession

engel s law and cointegration a time series counterpart of engel s law is that the expenditure share on food declines as the economy grows the main purpose of this paper is to test whether houthakker s addilog utility function can simultaneously explain this time series observation and cross sectional observations concerning engel s law ogaki and park s cointegration approach is used to estimate parameters of the utility function from time series data total expenditure elasticities implied by the estimated addilog utility function are compared with estimates of the elasticities from cross sectional data

structural adjustment policies in developing economies this paper examines structural adjustment policies in ldcs defined as policy responses to external or internal shocks that are carried out with the objective of regaining the pre shock growth path the introductory section of the paper reports on policy experience that indicates that countries applying an outward oriented development strategy were better able to cope with external shocks than economies following an inward oriented strategy it is further shown that the adoption of realistic exchange rates and interest rates the avoidance of large budget deficits and the productive use of the proceeds of foreign borrowing eased the process of adjustment the paper examines in detail the elements of a policy package that may be applied in response to external or internal shocks in the case prevalent in developing economies when optimal policies are not applied thus the recommendations simultaneously aim at responding to shocks and undertaking incentives incentives to save and to invest the choice of public investments sectoral policies in energy and agriculture budgetary policies and monetary policies in the conclusions the interdependence of the various policy measures is indicated with further attention given to foreign borrowing

patents and patent policy a patent is the legal right of an inventor to exclude others from making or using a particular invention this right is sometimes termed an intellectual property right and is viewed as an incentive for innovation this article surveys the evidence on patent effectiveness in encouraging innovation and reviews the current controversies in patent policy

the newly industrializing countries in the international system explanations of the growth of the newly industrializing countries nics by neoclassical economists and dependency theorists neglect the role of politics in shaping development strategies different social configurations state structures and ideas about development help explain the divergent policy choices made by the export oriented east asian nics korea and taiwan and the more inward looking countries of latin america particularly mexico and brazil these different strategic choices in turn account for variations in the patterns of external dependency that characterize countries in the two regions

the value of intellectual property rights to firms and society economists view intellectual property rights iprs as policy tools for encouraging innovation but they recognize that they can also inhibit competition there are many types of iprs and institutions concerned with their administration we begin by outlining how these complex and varied rights are supposed to work and how they interact with other characteristics of firms and markets we then survey the available literature on patents trade marks and copyright to assess the value of these iprs to firms and the costs to firms of acquiring and defending their rights the paper concludes with suggestions for topics requiring further research to inform public policy better

to protect or not to protect modes of appropriability in the small enterprise sector abstract what appropriation strategies are chosen by innovative small firms a cluster analysis of data from the german cis was carried out to indentify four distinct modes of appropriability in the small enterprise sector the results show that for many innovative small firms the key question is not whether to use intellectual property rights iprs or not but whether to protect their innovations from imitation at all furthermore formal and informal innovation protection mechanisms should not be seen as mutually exclusive since several are employed jointly secrecy and lead time advantages over competitors are often combined with iprs yet a number of small firms use complexity of design as a substitute to patent protection the relevance of each appropriation mode depends on such factors as the degree of innovativeness the type of innovator and the general market environment which implies that the importance of iprs is limited to specific business contexts furthermore regarding firm performance as measured by innovation effects some evidence is found that choosing both ipr and non ipr oriented appropriation strategies can prove to be effective in achieving company goals taken all together the study implies that the use of iprs by innovative small firms is highly selective the paper concludes with a discussion of the implications for policy and research

testing for homogeneity in demand systems when the regressors are nonstationary an implication of optimizing theory is that demand functions are homogeneous of degree zero in prices and nominal income evidence based on estimations of demand systems has repeatedly found this restriction to be rejected by the data however the hypothesis is often formulated in terms of regressors that are non stationary this paper re examines the evidence for homogeneity in light of recent developments in time series econometrics with special emphasis on the treatment of trends we find the demand system to be stochastically but not deterministically cointegrated using techniques developed for estimating cointegrating vectors in the presence of deterministic trends we re estimate the demand system and find that homogeneity holds in many cases

market value r d and patents abstract a significant relationship is found between the market value of the firm and its intangible capital proxied by past r d expenditures and the number of patents based on a time series cross section analysis of data for large u s firms

initiating private collective innovation the fragility of knowledge sharing incentives to innovate are a central element of innovation theory in the private investment model innovators privately fund innovation and then use intellectual property protection mechanisms to appropriate returns from these investments in the collective action model public subsidy funds public goods innovations characterized by non rivalry and non exclusivity in using these innovations recently these models have been compounded in the private collective innovation model where innovators privately fund public goods innovations private collective innovation is illustrated in the case of open source software development this paper contributes to the work on this model by investigating incentives that motivate innovators to share their knowledge in an initial situation before there is a community to support the innovation process we use game theory to predict knowledge sharing behavior in private collective innovation and test these predictions in a laboratory setting the results show that knowledge sharing is a coordination game with multiple equilibria reflecting the fragility of knowledge sharing between innovators with conflicting interests the experimental results demonstrate important asymmetries in the fragility of knowledge sharing and in some situations more knowledge sharing than theoretically predicted a behavioral analysis suggests that knowledge sharing in private collective innovation is not only affected by material incentives but also by social preferences such as fairness the results offer general insights into the relationship between incentives and knowledge sharing and contribute to a better understanding of the initiation of private collective innovation

technical and allocative inefficiencies and factor elasticities of substitution an analysis of energy waste in iran s manufacturing ignoring technical and allocative inefficiencies or embedding one of them alone in a system of input demands may result in biased elasticities we consider a comprehensive model including technical inefficiency in input and output forms and allocative inefficiency and apply it to panel data from iran s manufacturing sector the results show that the presence of both inefficiencies affects the computed elasticities of demand and substitution moreover in spite of current waste of energy in iran s manufacturing the elimination of environmental constraints will prompt the manufacturing firms to increase the utilization of energy relative to both capital and labor

subjective mortality expectations and consumption and saving behaviours among the elderly life expectancy is an important factor that individuals have to take into account for saving and consumption choices the life cycle model of consumption and saving behaviour predicts that consumption growth should decrease with higher mortality rates the aim of this study is to test this hypothesis based on data about subjective longevity expectations from the health and retirement study merged with detailed consumption data from two waves of the consumption and activities mail survey this study finds that an increase in subjective mortality by 1 corresponds to an annual decrease in consumption of non durable goods of around 1 8 l esperance de vie est un facteur important dont les personnes doivent tenir compte dans leurs choix de consommation et d epargne le modele de comportement de consommation et d epargne au cours du cycle de vie predit que la croissance de la consommation devrait decroitre a mesure que le taux de mortalite augmente cette etude met au test cette hypothese a l aide de donnees sur l esperance de vie subjective tirees des resultats d une etude sur la sante et la retraite arrimes aux resultats de deux vagues d enquetes postales sur la consommation et les activites qui ont produit des donnees detaillees sur la consommation cette etude montre qu un accroissement de un pour cent dans l anticipation subjective de mortalite correspond a un declin d a peu pres 1 8 dans la consommation annuelle de biens non durables

court decisions and equity markets estimating the value of copyright protection abstract we construct a database of u s federal court decisions pertaining to copyright and changes in federal statutory copyright law and use this database to assemble indices measuring changes in the breadth of copyright protection we combine our indices with information on excess returns to equity from a quarterly panel of firms and estimate how the breadth of copyright affects the market valuation of firm equity a typical statute that increases copyright breadth generates an increase in a firm s excess return to equity of 40 209 basis points depending on the exact time frame the size of the firm and the importance of the change in statutory law a typical high court decision expanding copyright generates a 13 105 basis point increase in excess returns our results are robust across 4 5 year subsamples and the size distribution of firms our statutory findings are strongest in the most recent portion of the sample

estimates of the value of patent rights in european countries during the post 1950 period this paper examines the distribution of the values of patent rights in the united kingdom france and germany during the post 1950 period these values are inferred from the behavior of patentees with respect to payment of renewal fees on their patents a simple economic model of renewal decisions is combined with data on the proportion of patents renewed at alternative ages and the renewal fee schedules to produce estimates of the distribution and the total value of patent rights in these countries moreover the data indicate that there have been changes in the value distribution and we follow these changes over the period the empirical results of particular interest concern the total value of patent rights and the relationship between changes in it and changes in the quantity of patents the skew in the distribution of patent values and the rate of obsolescence on the returns to patents

additive general error models for production cost and derived demand or share systems many empirical studies of production specify a deterministic model of the firm derive the implied behavioral equations input demand or share system and then embed this system in a stochastic framework by tacking on linear error terms in contrast this paper proposes general error models gems in which the error specification is an integral part of the optimization model these models are the statistical embodiment of stigler s view that apparent observed inefficiencies reflect the investigator s ignorance of the true optimization problem additive gems are proposed and interpreted specification tests indicate that a translog additive gem is superior to the standard translog specification

trade and structural change nics and next tier nics as transitional economies abstract the paper finds a strong association between rapid change in the sectoral composition of output and exports structural change and rapid export growth in the newly industrializing countries capital formation appears to be encouraged in dynamic economies by the underpricing of investment goods vis a vis consumption and government goods within these economies also the underpricing of investment goods in dynamic economies is relatively greater than in less dynamic economies whereas other research has found low price distortion to be associated with high growth and an outward rather than an inward looking orientation these associations are seriously challenged and more caution is urged in reaching generalized conclusions

a model of discovery empirical research has reached the puzzling conclusion that stronger patents do little or nothing to encourage innovation we show that the facts that have led to the assumption of fixed cost in the discovery process can be equally well explained by a standard model of diminishing returns this may explain much of the misunderstanding of the supposedly positive role of monopoly in innovation and growth thereby accounting for the empirical puzzle

age trend and cohort effects in a macro model of canadian expenditure patterns a quadratic almost ideal demand system allowing for age cohort and trend effects is developed at the macro level the model is estimated by maximum likelihood using a three tier iterative search method applied to pooled 1961 1992 time series for five regions of canada and six categories of expenditure hypothesis tests indicate support for the model specification elasticities are compared with those reported in other studies with special attention to food effects of demographic and trend variables on elasticities and expenditure shares are investigated an overall conclusion is that such effects can be very important in a macro demand system

endogenous growth cycles current explanations why a growing economy necessarily goes through periods of high and low growth predict countercyclical r d investment as this is very controversial from an empirical perspective a stochastic poisson model of endogenous growth cycles is presented where the determinants of the cyclical behaviour of r d investment are analytically studied providing an explicit expression for the expected length of a cycle shows that high frequency fluctuations can indeed be understood by this approach it is also shown how small technological improvements translate into large aggregate fluctuations

the economics of copyright fair use in a networked world the recent success of file sharing technologies such as napster has highlighted the economic question of whether copying increases or decreases the market value of copyrighted works contrary to michele boldrin and david k levine 2002 we show that napster type services are likely to reduce copyright value this economic question of the effect of copying on copyright value largely coincides with the legal question of whether copying is fair use the primary legal determinant of fair use or use that does not require authorization by the copyright holder is whether the use adversely affects the present or future economic value of the copyrighted work 1 however given this legal standard it is unclear why copyright holders ever disagree with the court regarding fair use our analysis shows that there is no inherent conflict between the court and copyrightholders with regard to particular uses but why there may be a conflict with regard to a technology that has both fair and infringing uses

the random utility hypothesis and inference in demand systems in this paper the authors examine the consequences of adopting the random utility hypothesis as an approach for randomizing a system of demand equations random utility models are appealing since they allow the usual assumption of deterministic utility maximizing behavior by each consumer to coexist with the apparent randomness across individuals that is exhibited by data their results show that the use of random utility models implies that the disturbances of the demand equations may not be homoskedastic but must be functions of prices and or income copyright 1989 by the econometric society

what do we learn about consumer demand patterns from micro data the aim of this paper is to assess the importance of using micro level data in the econometric analysis of consumer demand to do this we utilize a time series of repeated cross sections covering some 4 000 households in each of 15 years employing a number of different aggregation procedures we conclude that aggregate data alone are unlikely to produce reliable estimates of structural price and income coefficients however once certain aggregation factors as well as trend and seasonal components are included an aggregate model is not necessarily outperformed across all demand equations in terms of forecasting ability jel d12 c52 c31 the purpose of this paper is to develop a complete consumer demand system based on a time series of individual household data and to use it to measure the biases introduced into the study of consumer de mand behavior when aggregate data are used in place of the appropriate microeco nomic data we assess the suitability of ag gregate data through the impact on income and price elasticities and by evaluating the ability of both micro and aggregate based models to forecast aggregate consumer de mand the biases introduced by the use of aggregate data depend upon the way that household characteristics interact with in come and price effects and on departures of demand systems from linearity we explore the structure of microeconomic demand sys tems and the role of household characteris tics in the behavior of consumer demand both for the light this may shed on the pattern of future demands and for the im plications this behavior has for issues of aggregation consumer demand patterns typically found in micro data sets vary considerably across households with different household characteristics and with different levels of income we model this variability by making intercept and slope parameters in the budget share equations of our demand sys tem depend on household characteristics and by allowing for nonlinear total log expenditure terms in fact in theory consistent demand systems it is total ex penditure rather than disposable income that is allocated across goods we find that this general framework leads to a well specified data coherent demand system which is a quadratic extension of the popu lar almost ideal model of angus s deaton and john muellbauer 1980 the micro level estimates are shown to be sensitive to the treatment of endogeneity of total expen diture and to the specification of interaction terms with household characteristics in ad dition this specification is also shown to possess many attractive features for the evaluation of aggregate models

intellectual property the assessment in recent years there has been an increase in the commercialization of intellectual property ip via such mechanisms as patents licences copyrights and trade marks new institutions e g science parks as well as new organizational forms e g research joint ventures have emerged to facilitate the creation and commercialization of ip existing institutions most notably universities have become much more aggressive in protecting their ip and devising ways to generate additional revenue from their ip portfolios these trends have important policy implications which are addressed by the authors in this issue we summarize their contributions and provide some context for assessing these salient matters

quadratic engel curves and consumer demand this paper presents a model of consumer demand that is consistent with the observed expenditure patterns of individual consumers in a long time series of expenditure surveys and is also able to provide a detailed welfare analysis of shifts in relative prices a nonparametric analysis of consumer expenditure patterns suggests that engel curves require quadratic terms in the logarithm of expenditure while popular models of demand such as the translog or the almost ideal demand systems do allow flexible price responses within a theoretically coherent structure they have expenditure share engel curves that are linear in the logarithm of total expenditure we derive the complete class of integrable quadratic logarithmic expenditure share systems a specification from this class is estimated on a large pooled data set of u k households models that fail to account for engel curvature are found ro generate important distortions in the patterns of welfare losses associated with a tax increase

explaining the dynamics of the southeast asian political economy state society and the search for economic growth this essay reviews two sets of books that explore the origins and dynamics of southeast asia s growth and economic transformation one set of books utilizes a structuralist framework and emphasizes the role of the state in creating a now powerful capitalist class the other set of books utilizes an institutionalist framework to explain how new patterns of private public sector collaboration have resulted in rapid economic growth the authors point to weaknesses in both approaches and to areas where the two approaches can be fruitfully synthesized they also offer suggestions for future research
