section 337 and the protection of intellectual property in the united states the complainants and the impact under section 337 of the tariff act of 1930 a firm can challenge imports that infringe its u s intellectual property rights such as patents copyrights and trademarks based on publicly available information this paper examines the characteristics of firms that file complaints under section 337 and also evaluates how firms are affected by the outcomes we find a complaining firm compared with peer firms in the same industry is typically larger produces a more diverse range of products has invested more in intangibles and is no less profitable a finding of no violation significantly depresses the filing firm s profits compared to peers section 337 appears to protect innovators but its effectiveness in promoting more innovation cannot be demonstrated so clearly copyright 1996 by mit press

patent validation at the country level the role of fees and translation costs one feature of the european patent system that is heavily criticized nowadays is related to its complex fragmentation and the induced cost burden for applicants once a patent is granted by the epo the assignee must validate and often translate it and pay the renewal fees to keep it in force in each country in which the applicant seeks protection the objective of this paper is to assess to what extent validation and renewal fees as well as translation costs affect the validation behavior of applicants we rely on a gravity model that aims at explaining patent flows between inventor and target countries within the european patent system the results show that the size of countries their wealth and the distance between their capital cities are significant determinants of patent flows validation fees and renewal fees further affect the validation behavior of applicants translation costs seem to have an impact as well the important role played by fees suggests that the implementation of cost reducing policy interventions like the london protocol would induce a significant increase in the number of patents validated in each european country

a note on innovation and patent protection intertemporal imitation risk smoothing abstract in the presence of imitation risks a value maximizing firm intertemporally smooths those risks across current and future new technologies thus changes in patent protection levels can affect the timing of innovation by affecting an agent s motive for imitation risk smoothing

openness to trade in manufactures in the oecd abstract how open are the advanced economies to trade with each other in this paper openness is calculated relative to the predictions of the monopolistic competition trade model using data on manufacturing trade and production in the oecd in 1985 the paper finds that 1 japan imports much less than other large oecd countries while the european countries have larger import volumes than does the us 2 japan and the us engage in less intra industry trade than the rest of the oecd and 3 the eu countries are less open to imports from japan and the us than those countries are open to imports from the eu

foreign direct investment and intellectual property rights evidence from hollywood s global distribution of movies and videos abstract traditional thinking about intellectual property rights ipr suggests that as a country strengthens its ipr standards firms will move their governance structures away from equity based institutions such as foreign direct investment fdi towards more market based relations such as licensing agreements this hypothesis is explored by examining the behavior of hollywood studios in both the feature film and video markets in 40 foreign countries the analysis reveals that the behavior of hollywood studios is more complex than this although moderate iprs are associated with a high degree of licensing both high and low standards of ipr encourage more integrated governance structures

disguised protectionism and linkages to the gatt wto member states of the gatt wto have linked some issue areas outside trade to the institution and did so with varying depths at the same time they have chosen not to link other issue areas what accounts for this variation the author argues that states establish a legalized linkage between the gatt wto and an issue area outside it when they are uncertain about the possibilities of disguised protectionism such uncertainty exists under two conditions when diversity in regulations in an issue area across states generates a large adverse impact on trade negative externalities but that diversity can be justified at the international level for 1 having an independent objective apart from hampering trade and 2 when there are few alternative policies to achieve that objective legitimacy states establish a highly legalized linkage in these situations to reduce the uncertainty and minimize disguised protectionism by contrast when regulatory diversity exhibits low legitimacy states establish only a weakly legalized linkage in the absence of meaningful externalities they do not establish any linkages the author evaluates this argument in two ways he provides an overview of eleven issue areas about which there have been some debates or conflicts about linkages to the gatt wto in addition he carries out in depth case studies of three issue areas labor standards environmental standards and health safety standards the findings of this article contribute to a better understanding of international institutions and cooperation as well as of the evolution of the multilateral trade institution

trips trade and technology transfer a north south model of unintentional technology transfer is developed where the stringency of southern patent protection provides the institutional backdrop for a strategic game in a high tech goods market the appropriability regime is set endogenously and combines elements of imperfect southern patent protection with the protection afforded by market made northern technology masking less stringent protection of northern intellectual property can work much like other strategic trade policies therefore developed countries appear to be right in demanding discussion of intellectual property rights in gatt

fighting software piracy which governance tools matter in africa this article integrates previously missing components of government quality into the governance piracy nexus in exploring governance mechanisms by which global obligations for the treatment of iprs are effectively transmitted from international to the national level in the battle against piracy it assesses the best governance tools in the fight against piracy and upholding of intellectual property rights iprs the instrumentality of ipr laws treaties in tackling piracy through good governance mechanisms is also examined findings demonstrate that 1 while all governance tools under consideration significantly decrease the incidence of piracy corruption control is the most effective weapon 2 but for voice and accountability political stability and democracy ipr laws treaties are instrumental in tackling piracy through government quality dynamics of rule of law regulation quality government effectiveness corruption control and press freedom hence the need for a policy approach most conducive to expanding development is to implement an integrated system of both iprs and corollary good governance policies moreover our findings support the relevance of good governance measures in developing countries wishing to complement their emerging ipr regimes

an empirical investigation of the pollution haven effect with strategic environment and trade policy abstract using a new dataset on the stringency and enforcement of environmental policy this study is the first to find robust confirmation of a pollution haven effect in a cross country context by accounting for strategically determined environment trade and intellectual property right ipr policies a simple game theoretic approach to policy determination is described which suggests an identification strategy based on other country characteristics it is found that for the top 20th percentile of countries in terms of growth in u s multinational affiliate value added as much as 8 6 of that growth between 1999 and 2003 can be attributed to declining relative stringency and enforcement of environmental policy the results are robust to a number of identification tests weak iv tests and third country spatial effects further evidence is found that relatively footloose industries are more likely to be affected by environmental policy than more traditionally dirty industries and enforcement of environmental policies tends to be a more important deterrent than the stringency of the policy set

anti foreign bias in the court welfare explanation and evidence from canadian intellectual property litigations abstract are judges concerned in the same way as policy makers with the effects of their decisions on national welfare in this paper we analyze this question by examining the outcomes of intellectual property rights ipr litigations between domestic and foreign firms we use a simple model of oligopoly in which ipr takes the form of a more efficient production technology to illustrate how antiforeign bias varies across cases when judges have welfare concerns the predictions of the model are tested using data on all canadian ipr cases over a four year period we find that foreign firms have about 25 percentage points lower probability of protecting their ipr in canadian courts relative to domestic firms we also find that courts decisions are aligned with national welfare maximization principles so that foreign firms are less likely to win in those cases when the implied welfare gains from not protecting foreign ipr are greater these findings are robust to controlling for endogenous selection of firms into litigation

tariffs and capacity utilization by monopolistically competitive firms abstract this paper examines the effect of a tariff imposed on a monopolistically competitive mc sector on firm output in a 2 2 2 model with nonhomothetic technology if the mc sector is capital intensive then a tariff will improve the terms of trade lower home firm demand elasticity but raise firm output relative to foreign firms if the mc sector is labor intensive then excess supply for firm output may be decreasing in price so the tariff may worsen the home country s terms of trade home firm demand elasticity falls but firm output rises relative to the partner country these results qualify conclusions based on single sector and single country models

is trade in electrical and electronic products sensitive to ipr protection evidence from china s exports abstractthis article attempts to provide the first empirical evidence on the effect of intellectual property rights iprs on china s export of electrical and electronic products it adopts a gravity model for unbalanced panel data of china s 146 important trading partners over the period of 2002 2012 to eliminate the effects of fdi in determining the linkage between ipr and exports the panel excludes the destination countries and territories that invest in china the results reveal that the level of ipr protection in destination countries has a positive impact on china s flow of exports further analysis on data disaggregated by ipr score demonstrates that a higher level of ipr protection in destination countries and territories is positively linked with china s exports of these items in each of the ipr protection clusters and indicates a strong market power effect by the interplay between r d expenditure and ipr in the destinations finally both market power and market expansion effects are found to

foreign patent rights and high tech exports evidence from taiwan this paper conducts a consecutive pooled data analysis from 1989 to 2000 to investigate the relationship between foreign patent rights fprs and the exports of three high tech industries in taiwan the semiconductor the information and the communication equipment industries following smith s model setup empirical results indicate that both market expansion and market power effects do exist in taiwan s case in addition this paper proposes a new hypothesis in which the importing country may exhibit a stronger r d ability than the exporting country a case that has not been considered in earlier empirical work finally a test is made to determine if a trips trade related intellectual property rights agreement has any impact on the fprs exports relationship and no evidence is found of a structural change after the implementation of trips

bidding for brains intellectual property rights and the international migration of knowledge workers we introduce international mobility of knowledge workers into a model of nash equilibrium ipr policy choice among countries we show that governments have incentives to use iprs in a bidding war for global talent resulting in nash equilibrium iprs that can be too high rather than too low from a global welfare perspective these incentives become stronger as developing countries grow in size and wealth thus allowing them to prevent the poaching of their brains by larger wealthier markets

the dynamics of corruption with the ratchet effect this paper provides a simple model of corruption dynamics with the ratchet effect as in shleifer and vishny 1993 we consider the sale of government property entry permit by government officials as the prototype of corruption activities in a dynamic version of the shleifer vishny model corrupt officials have ex post the incentive to price discriminate entrepreneurs based on the entry decisions made in an earlier period we show that the inability of government officials to commit to future money demands induces the ratchet effect in that entrepreneurs have incentives to delay entry in order to receive a discount in the permit price later the ex post opportunism erodes the official s extortion power and reduces his revenues from selling permits even though the dynamic setting leaves the corrupt official with less extortion power we cannot rule out the possibility that the official s ability to apply dynamic discrimination decreases the intertemporal aggregate social welfare we also explore the effect of the official s tenure stability on the extent of corruption this allows us to identify circumstances under which the often observed practice of job rotation can help mitigate corruption

does stronger patent protection increase export variety evidence from us product level data proponents of global intellectual property rights iprs reforms have argued that developing countries weak iprs limit their access to foreign innovative products and technologies central to our understanding of the effects of iprs on product access is the influence of national differences in patent protection on corporate behavior and business strategy of multinational firms using detailed product data on us exports from 1990 to 2000 this research note assesses the impact of strengthening iprs in developing countries on product variety of us exports colonial origin and cross industry variation in patent effectiveness serve to identify the impact the results show that the strengthening of iprs increased exports of new products in patent sensitive industries the expansion in product variety accounted for the entire increase in us exports the findings substantiate claims that ratification of trips by developing countries promotes access to new foreign products and technologies additionally the results demonstrate that patent protection is a significant institutional factor in us firms business decisions over the introduction of new products and processes into a developing country marketplace

high animal welfare standards in the eu and international trade how to prevent potential low animal welfare havens future costs of compliance with obligatory animal welfare standards in the eu for poultry and egg production are signiwcant and may lead to relocation of production to third countries after an overview of diverent rationales for complementary policies to prevent relocation this article systematically compares such policies some policies like multilateral agreements and labelling may be supporting but may not be able to prevent relocation comprehensively compensatory payments to domestic producers in contrast are evective but disadvantage third country producers that comply with equivalent standards therefore tariv discrimination may be a better alternative a major drawback of tariv discrimination however is its severe institutional requirements future research questions include quantiwcation of potential relocation as well as transaction costs of various complementary policies

licensing versus direct investment a model of internalization by the multinational enterprise a firm must decide whether to serve a foreign market by exporting building a foreign branch plant or licensing the production to an existing foreign producer the existence of reputations implies that any licensing agreement must provide a licensee with the incentive to maintain the reputation this creates a motive for the firm to internalize transactions by building a branch plant i e by becoming a multinational the model reflects a more general notion that the inability of the firm to control a licensee s agent s actions can provide incentives for multinational activity the paper explores the determinants of the firm s mode of operation as well as the consequences of certain government policies

the impact of patent protection on us pharmaceutical exports to developing countries this article provides evidence that patent protection can have a positive effect on trade by analysing the impact of the implementation of intellectual property rights ipr in developing countries on the us exports of pharmaceutical products following intense lobbying efforts from the us pharmaceutical industry to have the trade related aspects of intellectual property rights trips agreement included in the creation of the world trade organization wto a gravity model using panel data from 1995 to 2010 suggests that the implementation of minimum standards of patent protection has increased us exports of pharmaceuticals to 108 nonadvanced countries

determinants of cross border intellectual property rights enforcement the role of trade sanctions with growing trade in a global economy the desire for trade protection becomes increasingly important one aspect of trade protection that has risen to the forefront is the protection of intellectual property rights ipr across national borders this article analyzes the determinants of u s filed investigations for alleged ipr cross border violations using the complete set of section 337 investigations conducted by the u s international trade commission usitc by analyzing political institutional and economic variables in an industry level model we find evidence that investigations are more frequent in industries that face intense import competition among ipr protected goods in addition greater technology access to u s patents by respondent firms is found to increase filings especially in countries where corruption levels are higher

patent rights and trade analysis of biological products medicinals and botanicals and pharmaceuticals this article analyzes the effects of foreign patent rights on u s bilateral exports the empirical analysis covers three highly disaggregated drug industries over three decades we estimate bilateral trade equations for each industry using cross country data on the strength of national patent rights the findings show that strong foreign patent rights enhance the market power of u s drug exporters across countries with weak imitative abilities alternatively strong foreign patent rights stimulate the market expansion of u s drug exports across countries with strong imitative abilities these effects are larger in magnitude during the 1980 90s relative to the 1970s copyright 2002 oxford university press

innovation inequality and intellectual property rights we examine whether income inequality explains innovation across countries the mechanism could be twofold first a large middle class could have an impact on institutions including intellectual property rights iprs which could in turn affect innovation second evidence from us economic history suggests direct linkages between middle class share and innovation via supply and demand effects using ive to address endogeneity we find that middle class share explains patterns of resident patenting while non resident patenting is driven more by exogenous factors and global integration our results illustrate an additional channel through which income inequality can impact long run growth

innovation intellectual property rights and economic development a unified empirical investigation two important strands of literature investigate the way the effect of intellectual property rights ipr on innovation depends on either the initial ipr level or the level of economic development we expand on this by studying their joint effect in a single unified empirical framework we find that the effect of ipr on innovation is more complex than previously thought displaying important nonlinearities depending on the initial levels of both ipr and per capita gdp the policy implications of this are examined and include the conclusion that a single global level of ipr is in general sub optimal

welfare effects of global patent protection this paper uses a simple model of invention and patent protection to examine the welfare effects of extending patent protection from the country where invention takes place to another country that is only a consumer of invented products it is shown that while the welfare of the inventing country certainly rises with the extension of patent protection that of the other country probably falls and may well fall by more than the increase in welfare of the inventing country in particular as patent protection is extended to a larger and larger portion of the world the effect on the welfare of the world as a whole of extending it to the rest of the world becomes negative

trips trade and growth a two country model of endogenous growth is employed to assess the importance of intellectual property rights to trade growth and technology transfer the paper provides theoretical results linking the intellectual property rights regime to trade patterns aggregate r d worldwide growth and aggregate welfare measures failure to provide patent protection for foreign made innovations forces innovators to employ less than the best practice research technologies reduces aggregate r d activities worldwide effectively eliminates technology transfer across countries and reduces worldwide growth copyright 1994 by economics department of the university of pennsylvania and the osaka university institute of social and economic research association

international diffusion and intellectual property rights an empirical analysis abstract does a stronger intellectual property rights regime lead to the faster diffusion of new products and technology while there is a presumption that this is the case our analysis of data on the international release patterns of hollywood movies suggests a more complex story although moderate standards of ipr encourage the spread of movies either very weak or very strong property rights tend to slow the speed with which american movies are released abroad this empirical finding is robust to a wide variety of specifications overall it appears that while some recognition of ipr may encourage diffusion very strong ipr may actually retard the speed of diffusion

when an importer s protection of ipr interacts with an exporter s level of technology comparing the impacts on the exports of the north and south using bilateral trade data of countries from 2000 to 2007 this paper contributes to the empirical literature on the role of intellectual property rights iprs in global trade the existing literature has focused on how iprs in the destination country affect exports from a source country in this paper we add an additional dimension the level of technology of the exporting country lt this is quite important for distinguishing the impact of iprs on the exports of developed and developing countries since the technology levels vary across countries at different stages of development and intellectual property rights better protect exports that are technologically advanced than exports that are imitative and potentially infringing by factoring in the level of technology lt our empirical analysis makes the case that iprs can act as a barrier to the exports from the south especially the rapidly catching up economies and thus be a source for the middle income trap phenomenon

infringement of intellectual property rights causes and consequences parallel revolutions in molecular biology and the legal framework that assigns intellectual property rights iprs to plant genetic resources have resultedin the emergence of agricultural biotechnology andthe introd uction of genetically modified gm products into the foodsystem iprs create economic incentives for research andd evelopment by making the innovator the residual claimant of the benefits associatedwith the new technology whereas iprs purport to protect intellectual property full appropriation of the benefits from the innovation is not a given when infringement of iprs i e piracy is profitable rational economic agents compliance with ipr provisions is by no means assured costly monitoring and enforcement are requiredto d eter unauthorized illegal use of the new technology experience from various countries aroundthe worldind icates that ipr enforcement is far from being perfect andmany successful innovations are

is there a case for non discrimination in the international protection of intellectual property abstract we evaluate the case for non discrimination in international patent protection when trade is not subject to any frictions barriers requiring national treatment nt does not affect the rate of innovation and welfare since unfavorable discrimination suffered abroad by innovators in the absence of nt is fully offset by favorable discrimination enjoyed by them at home when trade barriers exist however such international offsetting in patent protection is incomplete and innovation incentives are actually lower under nt by lumping domestic and foreign patent protection together nt blunts the overall effectiveness of patent protection in incentivizing innovation in the presence of trade barriers

are weak patent rights a barrier to u s exports abstract this paper assesses whether how and to what extent u s exports are sensitive to national differences in patent rights i estimate bilateral trade equations that account for trade distortions related to patent rights using data on state to country manufacturing exports in 1992 i find that weak patent rights are a barrier to u s exports but only to countries that pose a strong threat of imitation e g china the stronger patent rights required under the wto agreement increase u s exports to these high threat markets alternatively strengthening patent rights in countries that pose a weak threat of imitation reinforces monopoly power and reduces u s exports to these markets

patent rights and innovative activity evidence from national and firm level data global standards of patent protection have been strengthened and harmonized in recent years despite the heated policy debates and theoretical controversies empirical studies of the consequences for innovative activity are scant this paper contributes to the debate by providing an empirical analysis of the effects of patent strength on different aspects of innovative activity namely firm level research and development r d domestic patenting and foreign patenting the analysis employs an updated index of patent rights the results show the complexity of evaluating the effects of patent reform on innovative activity since the effects vary nonlinearly depending on the initial level of patent strength and vary by a country s level of economic development overall for developing economies patent strength negatively affects domestic patent filings and insignificantly affects r d and foreign patent filings for developed economies patent strength positively affects r d and domestic patent filings and negatively affects foreign patent filings after some critical level of patent protection is reached journal of international business studies 2007 38 878 900 doi 10 1057 palgrave jibs 8400306

intellectual property rights and the world trade organization retrospect and prospects this paper analyzes the main economic issues of intellectual property rights iprs protection in the context of the world trade organization wto a retrospective view on the establishment of the trips trade related aspects of intellectual property rights agreement a still controversial accomplishment of the uruguay round of trade liberalization is provided the paper reviews the economic rationale for the harmonization of iprs drawing both on economic theory considerations as well as emerging empirical evidence the logic of linking ipr protection and trade in the context of the wto is also re examined some specific attention is devoted to the implications of trips for agricultural and biotechnology innovations the impact that ipr protection can have in promoting growth and development and the relation of iprs with other economic policies is discussed the paper concludes with an analysis of the prospects for more or less iprs related consensus in the current round of wto negotiations

how trade related are intellectual property rights abstract there is little empirical evidence about whether differing international levels of patent protection influence trade flows if a nation strengthens its patent laws it could experience higher or lower imports we specify an empirical model in which deviations of bilateral sectoral imports from anticipated levels are related to income trade barriers and patent laws patent regulations in the importing country are corrected for endogeneity through the use of instrumental variables the results of the final equations indicate that increasing patent protection has a positive impact on bilateral manufacturing imports into both small and large developing economies

the political economy of international trade enduring puzzles and an agenda for inquiry a similar set of concepts has been central to the literatures on the formation of trade policy coalitions and the new economics of institutions the political and economic consequences of the degree to which assets are specific to a particular economic activity in this survey the authors take the necessary first step of summarizing the main findings of these two literatures and then suggest ways in which the issue might be joined in addition to providing a more coherent understanding of the findings of these two literatures and some new directions for them the authors show that many puzzles remain in the field of trade politics puzzles for which there are no appealing answers or where there are answers no strong evidence in support of them this essay then in addition to being a theoretical review of the literature puts forward an agenda for future study of international trade politics

entry reputation and intellectual property rights enforcement we examine how reputation concerns induce a multinational to partly withhold its entry into a developing country under weak intellectual property rights ipr enforcement equilibrium ipr violations are shown to arise only in the presence of such concerns holding constant a multinational s incentive to innovate better ipr enforcement encourages entry but reduces social welfare the multinational s incentive to innovate may be inversely u shaped in the strength of ipr enforcement if timed properly however stronger ipr enforcement can foster innovation without compromising social welfare testable implications concerning observable ipr violations are derived

the effect of patents on trade abstract in contrast with quotas and tariffs it is theoretically ambiguous whether fewer or weaker rules over intellectual property rights will increase or decrease trade in patentable goods the prevailing view is that anticipation of imitation reduces exporters incentive to export goods to jurisdictions with weak patent regimes this empirical paper uses new measures of how the destination country patent system can affect trade in contrast with existing studies which assume would be exporters can always get a patent in the target foreign market we construct measures of the bias against foreign patent applicants and patents which may block imported goods we find evidence that the presence of destination country blocking patents has the larger negative impact on international trade being refused a patent also has a negative impact on trade but the magnitude is smaller

do stronger patent rights raise high tech exports to the developing world abstract despite over 20 years of debate the trips agreement remains very contentious this paper evaluates the impact of strengthening patent rights prs in developing countries on developed countries exports over the 1962 2000 period colonial origin is used to isolate exogenous variation in prs the impact is then identified by examining the cross industry difference in sensitivity to prs i find that the increase in prs made in response to the trips agreement added about 35 billion 2000 us dollars to the value of developed countries patent sensitive exports into 18 developing countries this amount is equivalent to an 8 6 increase in these developing countries annual value of patent sensitive imports the increase in the value of exports was driven by a quantity rather than a price increase

intellectual property rights environmental regulations and foreign direct investment sustainable development has been a popular buzzword among policymakers and economists for over a decade although a key tenet of maintaining a sustainable development path for many economies rests on attracting mobile capital theoretical and empirical evidence into the institutional policies that attract factors remains largely unresolved this paper takes a positive look at the determinants of attracting capital with particular attention paid to intellectual property rights and environmental regulations

how do foreign patent rights affect u s exports affiliate sales and licenses abstract this paper analyzes how foreign patent rights fprs affect us exports affiliate sales and licenses our approach is distinctive in three ways we apply ownership location and internalization concepts to link fprs with servicing decisions we account for the simultaneity of servicing decisions we estimate the relative effects of fprs on exports affiliate sales and licenses empirical findings show strong fprs increase us affiliate sales and licenses particularly across countries with strong imitative abilities further fprs have a larger effect on us knowledge transferred outside the country and firm relative to knowledge located inside the country and internalized inside the firm

intellectual property rights in china the changing political economy of chinese american interests we review the evolution of modern chinese intellectual property right ipr laws and enforcement and explore economic and political forces involved in international conflicts over chinese ipr protection our analysis considers why the us and china moved from conflict to cooperation over intellectual property rights structural and institutional aspects of the political economy of iprs within each country are considered and data on chinese us trade in intellectual property intensive goods are examined we conclude that although enforcement of iprs within china continues to be relatively weak chinese ipr institutions are converging on those in the oecd nations

patent protection and the industrial composition of multinational activity evidence from u s multinational firms using data on u s firms technology licensing to local agents in developing countries this paper examines the impact of patent protection on internal and arms length technology transfer the effects of protection vary across products according to their complexity consistent with theories of internalization we find that patent reforms enable local firms to attract more arms length technology transfer especially of simple products which are relatively easy to imitate affiliated licensing also rises among simple products but falls among complex products the results withstand several robustness checks including controlling for endogeneity by using colonial origin as an instrument and are equally strong whether patent protection is measured by its intensity or by the timing of reforms the results have significance for patent policy in the developing world where access to knowledge is critical through arms length technology contracts proprietary knowledge diffuses beyond firm boundaries enabling local agents to access not only the protected technology but also know how

the convergence of utility and profit maximization the literature discussing the conditions leading to the convergence of utility and profit maximization for owner controlled firms has a long history scitovsky initiated the discussion and derived the important result that in the short run utility and profit maximization are necessarily equivalent only when the several indifference curves of the owner are vertical displacements of each other 10 59 hereafter we refer to indifference curves that are vertical displacements of each other as the scitovsky condition ladd 6 restates scitovsky s model in mathematical form and reaches the same conclusion piron 8 extends scitovsky s analysis to the long run and concludes that utility maximizers also maximize profit recent contributions to the literature examine the issue of convergence when the entrepreneur receives nonpecuniary benefits from managing the firm olsen 7 concludes that a utility maximizer who derives benefits from being self employed does not necessarily maximize profit in either the short or long run feinberg 2 3 4 and schlesinger 9 conclude that utility and profit maximization necessarily diverge when the nonpecuniary benefits cannot be obtained outside the firm in contrast hannan 5 argues that utility and profit maximization necessarily converge even when nonpecuniary benefits exist a theoretically precise measure of the opportunity cost of entrepreneurial activity is crucial to this discussion profit is total revenue less all the opportunity costs of production including entrepreneurial activity a theoretically precise measure of the opportunity cost of such activity is therefore a prerequisite for a precise measure of profit scitovsky uses the indifference curve passing through the point indicating the choice of total leisure to gauge the opportunity cost ladd and piron follow scitovsky s procedure olsen feinberg and schlesinger hereafter ofs use the wage rate foregone as the indicator of opportunity cost

trade related intellectual property rights industry variation and technology diffusion the wto inspired strengthening of intellectual property rights iprs in developing countries remains highly controversial even more than 15 years after the 1994 trips agreement this paper assesses how a strengthening of iprs aects international technology diusion by altering the volume of high tech exports into developing countries a simple north south general equilibrium model in which industries dier in their imitation rates is developed stronger iprs encourage northern rms in a wider range of industries to start exporting exports in industries with the highest risk of imitation rise while exports in other industries may fall international technology diusion does not necessarily fall with stronger iprs more technology diuses to the south because new high tech products are introduced in the southern market this works against the reduction in technology diusion caused by limited imitation
