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

grand innovation prizes a theoretical normative and empirical evaluation abstract this paper provides a systematic examination of the use of a grand innovation prize gip in action the progressive automotive insurance x prize a 10 million prize for a highly efficient vehicle following a mechanism design approach we define three key dimensions for gip evaluation objectives design and performance where prize design includes ex ante specifications ex ante incentives qualification rules and award governance within this framework we compare observations of gips from three domains empirical reality theory and policy to better understand their function as an incentive mechanism for encouraging new solutions to large scale social challenges combining data from direct observation personal interviews and surveys together with analysis of extant theory and policy documents on gips our results highlight three points of divergence first over the complexity of defining prize specifications secondly over the nature and role of incentives particularly patents thirdly the overlooked challenges associated with prize governance our approach identifies a clear roadmap for future theory and policy around gips

patents or prizes monopolistic r d and asymmetric information abstract in this paper a model of r d regulation is analysed to compare the effect of two types of asymmetric information on the welfare properties of patents and prizes as r d incentive instruments when there is a technological leader using the case of full information as a benchmark it is found that the trade off between patents and prizes does not change if the innovator s r d costs are private information whereas the relative efficiency of patents decreases if the government is less informed about the market for the innovation

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

beyond the hype intellectual property and the knowledge society knowledge economy this paper explores the debates surrounding whether or not we have now moved into a new knowledge economy andsor knowledge society and if so whether this shift is as significant and as far reaching as the industrial revolution in this possible transformation the place of information communications technologies has been crucial debate has occurred across both economics and sociology with differing emphases as is shown in the ranges of definitions that we review in the paper one consistent factor is the lack of clarity and consistency between them both within and across the disciplines in order to explore the issues that the debates raises in a more grounded way the paper explores them in relation to intellectual property ip and the intellectual commons in the process of innovation growth and economic development the paper is developed through an analysis first of the industrial revolution and the role within this of uncertainty technologies complementarities and elective affinities and the way ip was protected and controlled through patents secrecy being first to the market and copyright the second part of the paper examines definitions of the knowledge economy and society and the role within these of information communication technologies in order to explore whether the ways that ip is protected and controlled have changed in the debate about the knowledge economy and society the role of innovation via human capital with a greater reliance on intellectual capabilities has been emphasized the role of ip thus remains central but is now challenged by the rise of new forms of communication which make its protection harder and move much of the concern with respect to regulation to a global rather than national and local level copyright 2006 the authors journal compilation 2006 blackwell publishing ltd

the augmented latent class model incorporating additional heterogeneity in the latent class model for panel data abstract marketing researchers have actively sought to account for the heterogeneity in households preferences and responses to marketing mix elements e g price promotion when analyzing scanner panel data this is because not doing so biases response coefficient estimates that can potentially alter the conclusions drawn from such analyses in this article the authors present an extension to the latent class model lcm that accounts for additional heterogeneity by allowing households preferences to be a continuous mixture of segment level preferences the authors show how their model generalizes the lcm by the mere addition of s 1 parameters where s refers to the number of segments because a limitation of the traditional lcm is that it does not adequately account for heterogeneity in responses across households the authors model mitigates this criticism leveled at the lcm they then compare their model with the traditional lcm and the equivalent continuous mixture random effects models in

the peter pan syndrome in emerging markets the productivity transparency trade off in it adoption firms invest in technology to increase productivity yet in emerging markets where a culture of informality is widespread information technology it investments leading to greater transparency can impose a cost through higher taxes and the need for regulatory compliance the tendency of firms to avoid productivity enhancing technologies and remain small to avoid transparency has been dubbed the peter pan syndrome we examine whether firms make the trade off between productivity and transparency by examining it adoption in the indian retail sector we find that computer technology adoption is lower when firms are motivated to avoid transparency specifically technology adoption is lower when there is greater corruption but higher when there is better enforcement and auditing so firms have a higher productivity gain threshold to adopt computers in corrupt business environments that suffer from patchy and variable enforcement of the tax laws not accounting for this motivation to hide from the formal sector underestimates productivity gains from computer adoption thus in addition to their direct effects on the economy enforcement auditing and corruption can have indirect effects through their negative impact on adoption of productivity enhancing technologies that also increase operational transparency

a factor analytic probit model for representing the market structure in panel data internal market structure analysis infers both brand attributes and consumer preferences for those attributes from preference or choice data the authors exploit a new method for estimating probit models from panel data to infer market structures that can be displayed in few dimensions even though the model can represent every possible vector of purchase probabilities

software piracy an analysis of protection strategies software piracy by users is generally believed to harm both software firms through lower profits and buying customers through higher prices thus it is thought that perfect and costless technological protection would benefit both firms and consumers the model developed here suggests that in some circumstances even with significant piracy not protecting can be the best policy both raising firm profits and lowering selling prices key to the analysis is joining the presence of a positive network externality with the fact that piracy increases the total number of program users the network externality exists because consumers have an incentive to economize on post purchase learning and customization costs

the evolution of the industrial organisation of the production of knowledge this work elaborates the notion of localised technological knowledge based upon the distinction between information competence and knowledge and analyses the emergence of the new knowledge industry the evolution of the organisation of knowledge production is analysed through four stylised modes scientific entrepreneurship institutional variety vertical integration and technological cooperation the new trends towards the growth of knowledge intensive business service industries are detected and underlined they are considered as the outcome of the institutional formation of a market for knowledge based upon a process of increasing appropriability of localised knowledge based on the blending of generic scientific information and competence and growing scope of applicability via computercommunication systems deverticalisation of research activities from the boundaries of corporations the specification of a demand for technological competence and the specialising of independent firms in the production of technological competence and knowledge

an introduction to the law and economics of intellectual property although economists have written on topics of intellectual property for a long time the impact of economics on public policy in this area has been slight especially as compared to the influence of professional writings in areas such as antitrust and taxation we believe that too few of the profession s resources have been devoted to these issues and that of those resources that have been employed too few have been devoted to empirical analyses we hope that this introductory essay and the three papers that follow will stimulate interest in this subject this introductory essay first describes some of the basic economic tradeoffs involved in intellectual property law and then describes the framework of the law in the six areas described above patent copyright semiconductor protection trademark trade secret and misappropriation it is intended both to provide thumbnail descriptions of the various intellectual property regimes to economists working in this area and to indicate where additional economic research might be useful

modeling purchase timing and brand switching behavior incorporating explanatory variables and unobserved heterogeneity the authors use a continuous time semi markov approach to analyze in a single framework the purchase timing and brand switching decisions of households for a frequently purchased product the analysis provides more insights into the dynamics of household purchase behavior than could be obtained from conventional discrete choice models such as logit or probit the authors find that the probability distribution of interpurchase times is not the same for various switching between brands revealing extra information about the purchase timing decisions further they find that though the marketing mix and household demographic variables explain a large part of the variation in the brand switching rates they account for only a small part of the variation in the repeat purchase rates another finding from the analysis is that the rates of switching between brands due to promotional activities such as special displays and price reductions are in reverse order to the share of purchases of the various brands

market structure and performance in intellectual property the case of copyright collectives abstract copyright collectives are associations to whom authors transfer copyrights for purposes of exploitation these collectives grant licenses for the use of works in their repertory they negotiate and collect royalties which they distribute to their members and they take legal actions against those who infringe the copyrights to which they hold title this paper investigates the consequences of the formation of collectives on the number of copyrighted works produced and circulation of these works in the framework of a model of joint production welfare issues are also addressed

innovation policy for directing technical change in the power sector this paper discusses policy instruments for redirecting technical change within the electricity sector to mitigate climate change first we unravel the mechanism behind directed technical change explaining why markets may underprovide innovations in expensive renewable technologies in comparison to innovations in energy efficient fossil fuel generators subsequently we characterize technical change in electricity generation technologies stressing the heterogeneity of knowledge spillovers both within and between clean electricity generation technologies we argue that there exists a rationale for a portfolio approach to innovation in the electricity sector i e optimal innovation policies are neither fully generic nor fully specific and they need to be adapted in response to new information learned by the government the existing innovation literature does not however provide a clear cut answer for designing such a policy we compare policy instruments and argue that public r d support to clean technologies either in the form of subsidies or prizes seems to be the prime candidate for implementing non generic innovation policy

the effects of increased copyright protection an analytic approach previous authors who have considered partially nonexcludable goods have claimed that an increase in copyright protection will have the following two effects on social welfare first it will decrease the social welfare loss due to underproduction second it will increase the social welfare loss due to underutilization in this paper we investigate these claims in a formal setting by analyzing a model in which consumers vary only in terms of their costs of obtaining a reproduction our analysis provides partial support to the first claim of these previous authors while giving little or no support to the second claim

measuring the effects of new brand introduction on inter brand strategic interaction this paper empirically investigates the effects of a new brand introduction on the market structure of a product market i e the nature of competition among existing brands the model is based on the discrete choice multinomial logit model in which the household specific brand intercepts are decomposed into brand locations in attribute space and households importance weights for these attributes the formulation also incorporates the effects of marketing variables on brand choice behavior the relative proximity of brands in the attribute space provides a measure of the intensity of competitive rivalry among brands a new brand introduction results in an additional location in this space three consequences of the introduction are investigated i impact on brand locations of extant brands ii change in the importance weights assigned by households to the attributes iii effects on households sensitivities to marketing activities as some or all of the above could change these three effects result in eight combinations that need to be studied the general model is one in which all three components are allowed to change and this nests the remaining seven specifications the specification that is most consistent with the data can therefore be isolated via a statistical test of nested hypotheses identifying the consequences of the introduction for market structure has implications for managerial action an empirical application of the model to household scanner panel data using liquid laundry detergents is provided

encouraging private sector research for tropical agriculture summary agricultural needs in poor tropical countries differ significantly from those in temperate rich countries yet little agricultural research is performed on products for the tropics private research is particularly concentrated in rich countries this is a result of significant failures in the market for research and development r d in particular the difficulty of preventing the resale of seed in developing countries to encourage private r d in tropical agriculture traditional funding of research may be usefully supplemented by a commitment to reward developers of specific new agricultural technologies rewards tied to adoption may be especially useful in increasing up take an illustration of how a commitment to reward developers of new agricultural technologies might work is provided

the economics of invention incentives patents prizes and research contracts though public intervention in the market for research is virtually universal economists have paid surprisingly little attention to the choice of the form of research incentive in a given market structure many studies concentrate on patents but any assumption of their superiority over other incentives has been founded on intuition rather than on formal analysis in this paper i analyze the choice between three of the most common alternative means of public intervention in the research market namely patents prizes and direct contracting for research services i show why and under what conditions any one of the three may be preferred by a social welfare maximizing administrator in a competitive economy using a model that for the first time pays explicit attention to differences in the informational roles of each of these alternatives in the extensive literature on the economics of patents see arnold plant 1934 fritz machlup 1958 charles taylor and z a silberston 1973 morton kamien and nancy schwartz 1975 and f m scherer 1977 for valuable surveys formal analysis weighs the benefits of patents as a solution to the market failure associated with the inappropriability of knowledge against the welfare cost due to the restriction on the use of the knowledge generated and this tradeoff is optimized by patent life adjustment in william nordhaus 1969 scant analytical attention is paid to alternative incentive mechanisms an exception is ben yu 1981 who considers the role of prior contracting for inventions but as many writers for example dan usher 1964 yoram barzel 1968 joseph stiglitz 1969 carole kitti 1973 glenn loury 1979 partha dasgupta and stiglitz 1980a have pointed out in various contexts the incentive offered by an unlimited patent to competitive researchers may be excessive due to the common pool problem discussed further in section i below if the patent administrator and researchers share the same information as implicitly assumed in previous models then the patent life limitation can be adjusted to provide the optimal patent incentive given the common pool problem but in all such models patents would not be chosen in a fully optimized fiscal system researchers and the administrator are assumed to have identical information about the shadow price of potential inventions a patent is just a means of turning this shadow price into a monetary reward but monetary compensation can instead be offered directly to researchers by the state assuming that patent revenues incur a higher deadweight loss than an equivalent amount of public funds financed by less distortionary means for example a minimally efficient tax system appropriate prizes or government contracts are socially preferable to patents with optimal lives if the patent is ever to be the optimal incentive mechanism for research it must possess advantages not captured in existing models informal discussions of patents emphasize their informational role to include the latter as a justification for decentralized invention incentives i incorporate an ex ante imbalance of information about costs and benefits of research in the model presented in section ii but this alone is not quite enough it is further necessary to specify that the terms of the award must be fixed before department of economics economic growth center box 1987 yale station yale university new haven ct 06520 i thank with the usual caveat marguerite alejandro wright cindy arfken martin baily nuong brennan steven englander robert evenson richard levin richard nelson susan rose ackerman denis wright and two referees for assistance of various kinds

intellectual property the law and economics approach he traditional focus of economic analysis of intellectual property has been on reconciling incentives for producing such property with concerns about restricting access to it by granting exclusive rights in intellectual goods that is by propertizing them thus enabling the owner to charge a price for access that exceeds marginal cost for example patentability provides an additional incentive to produce inventions but requiring that the information in patents be published and that patents expire after a certain time limit the ability of the patentee to restrict access to the invention and so a balance is struck is it an optimal balance this question and the broader issue of trading off incentive and access considerations has proved intractable at the level of abstract analysis with the rise of the law and economics movement the focus of economic analysis of intellectual property has begun to shift to more concrete and manageable issues concerning the structure and texture of the complicated pattern of common law and statutory doctrines legal institutions and business practices relating to intellectual property among the issues discussed in this paper are the length of protection for intellectual property the rules that allow considerable copying of intellectual property without permission of the originator the rules governing derivative works and alternative methods of providing incentives for the creation of intellectual property the emphasis is on copyright law which perhaps because of its complex legal structure and the relative neglect by economists of the arts and entertainment has tended to be slighted in the conventional economic analysis of intellectual property relative to patent law where economic analysis can draw on an extensive literature concerning the economics of innovation i also srichard a posner is a judge of the u s court of appeals for the seventh circuit and a

the polarization of the u s labor market this paper analyzes a marked change in the evolution of the u s wage structure over the past fifteen years divergent trends in upper tail 90 50 and lower tail 50 10 wage inequality we document that wage inequality in the top half of distribution has displayed an unchecked and rather smooth secular rise for the last 25 years since 1980 wage inequality in the bottom half of the distribution also grew rapidly from 1979 to 1987 but it has ceased growing and for some measures actually narrowed since the late 1980s furthermore we find that occupational employment growth shifted from monotonically increasing in wages education in the 1980s to a pattern of more rapid growth in jobs at the top and bottom relative to the middles of the wage education distribution in the 1990s we characterize these patterns as the u201cpolarization u201d of the u s labor market with employment polarizing into high wage and low wage jobs at the expense of middle wage work we show how a model of computerization in which computers most strongly complement the non routine abstract cognitive tasks of high wage jobs directly substitute for the routine tasks found in many traditional middle wage jobs and may have little direct impact on non routine manual tasks in relatively low wage jobs can help explain the observed polarization of the u s labor market this abstract was borrowed from another version of this item

estimation of latent class models with heterogeneous choice probabilities an application to market structuring recently grover and srinivasan developed a latent class based approach to analyze market structure by using brand switching data the authors provide an iterative maximum likelihood procedure for

inducement prizes and innovation we examine the effect of prizes on innovation using data on awards for technological development offered by the royal agricultural society of england at annual competitions between 1839 and 1939 we find large effects of the prizes on competitive entry and we also detect an impact on patents especially when prize categories were set by a strict rotation scheme thereby mitigating the potentially confounding effect that they targeted only hot technology sectors prizes encouraged competition and medals were more important than monetary awards the boost to innovation we observe cannot be explained by the re direction of existing inventive activity

computerisation and wage dispersion an analytical reinterpretation the rich countries have recently seen a dramatic rise in income inequality all the more surprising because the long term trend had been toward equality this paper examines one of the leading explanations computerisation in the workplace i offer a theory of computers impact on white collar work which goes far toward explaining the timing form and locus of recent labour market changes the theory looks at the bureaucratic and organisational applications of computers that have been first largest and most influential they have two effects on firms demand for labour at different skill levels

an investigation into the order of the brand choice process this paper investigates the order of the brand choice process at the individual family level using a variety of tests t likelihood ratio binomial runs and multinomial runs tests the test of stationarity developed permits separate analyses for stationary and nonstationary purchase sequences our analyses indicate that the purchase sequences of a majority of stationary consumers are consistent with the zero order assumption this result is observed for all the nine frequently bought packaged goods studied with the use of panel data and for a product category soft drinks using experimental data

designing climate mitigation policy this us paper provides an exhaustive review of critical issues in the design of climate mitigation policy by pulling together key findings and controversies from diverse literatures on mitigation costs damage valuation policy instrument choice technological innovation and international climate policy the authors begin with the broadest issue of how high assessments suggest the near and medium term price on greenhouse gases would need to be both under cost effective stabilization of global climate and under net benefit maximization or pigouvian emissions pricing the remainder of the paper focuses on the appropriate scope of regulation issues in policy instrument choice complementary technology policy and international policy architectures

university research intellectual property rights and european innovation systems this paper surveys the literature on university patenting from the point of view of the economic theory of patents it is argued that patenting knowledge developed by university researchers is paradoxical patents are normally intended to stimulate knowledge development by providing property rights but universities operate also under a different incentive scheme i e they receive public funds to perform socially useful knowledge in the debate surrounding the so called bayh dole act in the usa it has however been argued that patents on university inventions may be necessary to stimulate technology transfer from universities to private firms the first part of the paper addresses two major questions first what is the economic logic of bayh dole and second what were the effects on universities and the knowledge they develop in the second part the paper addresses the issue of whether bayh dole like legislation would be beneficial for european countries in a number of european countries a suggestion has been made that this could enhance knowledge transfer from the public to the private sector using a new database resulting from a survey among patent inventors in six european countries an assessment is given of the degree of university patenting in europe because university researchers are often involved in patented inventions without the university being listed as a patent applicant statistics based on the patent office databases alone often underestimate university patenting in europe the paper ends with a discussion of how this european practice of university patenting affects public private knowledge transfer in europe and how this compares to the effects of the bayh dole act in the usa

buying sharing and renting information goods information goods such as books journals computer software music and videos can be copied shared resold or rented when such opportunities for sharing are present the content producer will generally sell a smaller amount at a higher price which may increase or decrease profits i identify three circumstances where profits increase 1 when the transactions cost of sharing is less than the marginal cost of production 2 when content is viewed only a few times and transactions costs of sharing are low and 3 when a sharing market provides a way to segment high value and low value users

does entry regulation hinder job creation evidence from the french retail industry are product market and entry regulation key sources of low employment growth in many european countries we investigate this question in the context of the french retail trade industry since 1974 approval by regional zoning boards has been required for the creation or extension of any large retain store in france we exploit a unique database that provides time and region specific variation in boards approval decisions we show that stronger deterrence of entry by the boards increased retailer concentration and slowed down employment growth in france

indigenous knowledge and intellectual property a sustainability agenda the paper argues that the current ways of protecting intellectual property are limited in their scope for recognizing indigenous rights to indigenous knowledge indigenous knowledge is often defined as being holistic and collectively owned and an appropriate protection should allow for maintaining the cultural and physical environment that has generated it after examining the failure of the patent system to recognize indigenous input using examples from the us patent and trademark office the analysis is directed towards alternatives the world s first case of indigenous intellectual accreditation through the partnership between mt romance australian sandalwood company aveda us based multinational cosmetics corporation and the kutkabubba community represented by the songman circle of wisdom is presented the accreditation allows for the indigenous people to be recognized as traditional owners of the land and for their care and knowledge about the sandalwood trees it also gives them a share of the profits made from the contemporary use of the pure sandalwood oil the paper argues that sustainability and indigenous sustainability in particular provides a conceptual framework for a change in the way of protecting intellectual property this implies that appropriate policies should be put in place for businesses to feel responsible towards the community

estimating loyalty and switching with an application to the automobile market a brand switching model that considers the choices previous choice current choice and substitute choice if the current choice were not available is developed and estimated an important assumption of the model is that the market consists of two types of consumers loyals and shoppers the model provides estimates for 1 the proportion of loyals in a submarket and 2 the success of each submarket in capturing shoppers we illustrate how the model can be used to characterize the competitive structure of a market we also show how the estimated parameters of the model can be validated using simulation and a theoretically derived covariance matrix our empirical application to automobile data from j d power and associates provides insights into several interesting marketing phenomena including 1 the competitiveness of domestic versus foreign makes of automobiles 2 competition between submarkets defined by form and 3 the effect of previous dealer experience on loyalty and shopping

the wto as a mechanism for securing market access property rights implications for global labor and environmental issues can the world trade organization wto contribute to the attainment of sound labor and environmental policies an answer requires an understanding of wto rules we argue that the purpose of wto rules is to create a negotiating forum where governments can exchange secure market access commitments from this perspective we argue that supporters of sound trade labor and environmental policies can benefit from a well functioning wto because facilitating trade liberalization and preventing race to the bottom regulatory chill problems go hand in hand and each is accomplished by maintaining secure property rights over negotiated market access commitments

computer usage and labour regulation in india s retail sector abstract a recent survey of 1 948 retail stores in india conducted by the world bank s enterprise surveys shows that 19 per cent of all stores use computers in the state of kerala the figure is as high as 40 per cent using this survey we estimate the effect of computer usage on labour employment our findings show that this effect depends on the stringency of the underlying labour laws stricter labour laws magnify the labour displacing effect of computers significantly

the welfare implications of unauthorized reproduction of intellectual property in the presence of demand network externalities this paper finds that unauthorized reproduction of intellectual property in the presence of demand network externalities can not only induce greater firm profits relative to the case where there is no copying it can lead to a pareto improvement in social welfare ceteris paribus when network externalities are present firms have a greater incentive to expand output because marginal revenue is higher and or they may wish to create preemptive installed bases this paper suggests that unauthorized copying can be a relatively efficient means of achieving this by allowing the firm in effect to price discriminate among different classes of consumers copyright 1994 by blackwell publishing ltd

the structure of a contract and the theory of a non exclusive resource the process of arriving at a useful concept of analysis is not only slow and painful but also may go astray and attain nothing useful someone begins with one example or observation followed by a theory which is intuitively plausible a theoretical term associated with a vague concept is coined examples of a seemingly different type emerge which call for another theory the process goes on as examples and theories continue to accumulate the different categories under the same heading of analysis serve only to confuse and each associated theory becomes ad hoc such has been the fate of the concept of externality a more useful approach i think is via contractual conditions the example chosen for illustration is marine fisheries where the fishing right is taken

the regulation of labor author s botero juan djankov simeon la porta rafael lopez de silanes florencio shleifer andrei abstract we investigate the regulation of labor markets through employment collective relations and social security laws in 85 countries we find that the political power of the left is associated with more stringent labor regulations and more generous social security systems and that socialist french and scandinavian legal origin countries have sharply higher levels of labor regulation than do common law countries however the effects of legal origins are larger and explain more of the variation in regulations than those of politics heavier regulation of labor is associated with lower labor force participation and higher unemployment especially of the young these results are most naturally consistent with legal theories according to which countries have pervasive regulaory styles inherited from the transplantation of legal systems

inferring the order of the choice process using consumer purchase histories the small sample properties of the multinomial runs mr test which is often used to test for effects of previous brand choices on current brand choice probabilities are explored in this article through a monte carlo study of different buyer level brand choice probability models the power and the actual size of this test under a null hypothesis of no previous brand choice effects are shown to depend on the nature of the true underlying model length of purchase history and skewness in baseline choice probabilities we provide some guidelines for when the mr test is more useful in empirical research

preemptive patenting and the persistence of monopoly this article takes a different tack and inquires whether institutions such as the patent system create opportunities for firms with monopoly power to maintain their monopoly power the results apply to other situations such as brand identification spatial location and capacity expansion which share the characteristic that early or preemptive actions may lower the returns to potential competitors

consumer s surplus without apology the purpose of this paper is to settle the controversy surrounding consumer s surplus and by so doing to validate its use as a tool of welfare economics i will show that observed consumer s surplus can be rigorously utilized to estimate the unobservable compensating and equivalent variations the correct theoretical measures of the welfare impact of changes in prices and income on an individual i derive precise upper and lower bounds on the percentage errors of approximating the compensating and equivalent variations with consumer s surplus these bounds can be explicitly calculated from observable demand data and it is clear that in most applications the error of approximation will be very small in fact the error will often be overshadowed by the errors involved in estimating the demand curve the results in no way depend upon arguments about the constancy of the marginal utility of income consequently this paper supplies specific empirical criteria which can replace the apologetic caveats frequently employed by those who presently apply consumer s surplus moreover the results imply that consumer s surplus is usually a very good approximation to the appropriate welfare measures to preview below i establish the validity of these rules of thumb for a

copying and indirect appropriability photocopying of journals creators and owners of intellectual properties are alarmed by the growth of technologies that ease the tasks of copying these properties this paper however shows that the unauthorized copying of intellectual properties need not be harmful and actually may be beneficial the empirical impact of photocopying on publishers of journals is examined in an attempt to discover if publishers can indirectly appropriate revenues from users who are not original purchasers the evidence indicates that publishers can indirectly appropriate revenues from users who do not directly purchase journals and that photocopying has not harmed journal publishers 18 references 1 table

hybrid innovation in meiji japan japan s hybrid innovation system during the meiji era provides a useful laboratory for examining the effectiveness of complementary incentives to patents patents were introduced in 1885 and by 1911 1 2 million mostly nonpecuniary prizes were awarded at 8 503 competitions prizes provided a strong boost to patents especially in less developed prefectures and they also induced large spillovers of technical knowledge in prefectures adjacent to those with prizes relative to distant control prefectures without prizes linking competition expenditures with the expected market value of patents induced by the prizes permits a cost benefit assessment of the prize competitions to be made

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

market structure innovation and optimal patent life m uch work has been directed at determining the relative efficiency of various market structures in the allocation of resources to invention while the conclusions are not entirely clear it seems certain that no single market structure results in a pareto efficient allocation of resources to research and development r d in the light of this certain secondbest procedures must be examined social controls may provide an attractive method of lessening the inefficiencies described above 2 while government research and development subsidies and award programs do exist the most prevalent form of social control is the patent system granting the inventor a monopoly on the use of the discovery for a specified period of time eliminates the free rider problem thus restoring the incentive to invent extension of the duration of protection will increase incentives for private resource allocation toward technical advance unfortunately extension of patent protection by definition brings with it the social inefficiencies recognized in a monopolistic market the

market structure and innovation a survey economics we all recite deals with allocation of limited resources towards satisfaction of unlimited wants resources are typically identified as land labor and capital plus a technology that determines their transformation into consumer goods disparity between the available goods and services and the desired gives rise to scarcity and the question of what how and for whom to produce the focus then shifts to description and evaluation of alternative resource allocation mechanisms for making the choices the pareto criterion by which an allocation of resources is deemed efficient if any reallocation improving the position of some individual worsens the position of others is a commonly employed gauge of a mechanism s performance in the absence of externalities increasing returns to scale and uncertainty a perfectly competitive market system yields a pareto optimal allocation of resources this underlies the view that individual self interest is compatible with society s interest the further conclusion that pareto optimality may not be achieved via the market system in the presence of monopoly elements provides an economic rationale for antitrust laws the objective of a resource allocation mechanism appears to be according to the analysis described above to make the best of available resources the alternative objective of relaxing constraints through expanding the resource base or developing new technology seems to be beyond its scope thus until rather recently technical advance had been regarded in the mainstream of economic theory as unmotivated by the quest for profits and substantially unaffected by resource allocation instead as j schmookler observed technology had been viewed as a parameter like the weather affecting the outcome of resource allocations but itself unaffected by them 84 1965 evidence that technological progress has significantly contributed to growth in productivity together with a substantial increase in research and development activity largely financed by government and carried out by industry see f machlup 51 1962 may have spurred reconsideration of this view once technical advance is regarded as an economic variable it is natural to in

performance responses to competition across skill levels in rank order tournaments field evidence and implications for tournament design tournaments are widely used in the economy to organize production and innovation we study individual data on 2775 contestants in 755 software algorithm development contests with random assignment the performance response to added contestants varies nonmonotonically across contestants of different abilities precisely conforming to theoretical predictions most participants respond negatively whereas the highest skilled contestants respond positively in counterfactual simulations we interpret a number of tournament design policies number of competitors prize allocation and structure number of divisions open entry and assess their effectiveness in shaping optimal tournament outcomes for a designer

the role of knowledge in r d efficiency past research has recognized that both demand and capability influence the allocation of r d resources scholars have had an easier time getting a grip on demand than on capability while it has been recognized that knowledge is an important part of capability to date formalization of knowledge and its role in r d activity has been unsatisfactory this paper models the role of knowledge in r d various sources of such knowledge are considered the model throws a different light on analyses that employ a knowledge capital stock and also illuminates the dual private and public nature of technological knowledge

the merits of new pollutants and how to get them when patents are granted the performance of market based environmental regulation is affected by patents and vice versa this interaction is studied for a type of innovation where a new technology reduces emissions of a specific pollutant but at the same time causes a new type of damage if the new pollutant associated with this technology is sufficiently different from existing ones such that marginal damage is increasing in each of them but additive across pollutants a diversification of the pollution portfolio is socially desirable in a situation where the incentives to develop such a technology are created by patents the efficiency of permits is affected by monopoly pricing of the patent holding firm this result carries over to other types of innovation the performance of taxes is limited by either the inability to implement specific pollution mixes or monopoly pricing for constant returns to scale at the industry level the combined use of taxes and permits ensures the first best mix of technologies and provides positive research incentives
