patent protection in developing countries and global welfare wto obligations versus flexibilities abstract this paper develops a north south model to evaluate the south s incentive for patent protection when a northern firm s investment in quality enhancing research and development r d is affected by its patent policy the model is used to a evaluate the impact of requiring the south to fulfill its key wto obligation of instituting patent protection and b to address the role of two major flexibilities that wto members enjoy with respect to their patent policies the freedom to implement exhaustion policies of their choosing and the right to use compulsory licensing cl subject to certain stipulations two forces drive the model how much the firm invests in r d and whether or not selling in the south maximizes its global profit cl improves consumer access in the south and can even raise innovation and global welfare provided the south implements patent protection innovation and welfare are higher if the north follows national as opposed to international exhaustion however the south s incentive for patent protection is not necessarily stronger under national exhaustion not only is cl more likely to be used under international exhaustion the welfare gain resulting from its application is also higher relative to that under national exhaustion

the value of tax shields is not equal to the present value of tax shields abstract the value of tax shields is the difference between the present values of two different cash flows each with their own risk the present value of taxes for the unlevered company and the present value of taxes for the levered company for constant growth companies the value of tax shields in a world with no leverage cost is the present value of the debt times the tax rate times the unlevered cost of equity discounted at the unlevered cost of equity this result arises as the difference of two present values and does not mean that the appropriate discount for tax shields is the unlevered cost of equity

the structure of licensing contracts industrial organization theory has explored several issues related to licensing but empirical analyses are extremely rare we amass a new and detailed dataset on licensing contracts and use it to present some simple facts concerning licensing behavior our analysis reveals robust cross industries differences in several contractual features such as exclusivity cross licensing ex ante versus ex post technology transfers and licensing to related versus unrelated parties we offer an interpretation of these facts based on cross industry variation in the strength of intellectual property rights

equilibrium parallel import policies and international market structure in a north south vertically differentiated duopoly the analysis in this paper derives equilibrium government policies towards parallel imports by incorporating strategic interaction at the policy setting stage and the product market the model sheds new light on i the effects of parallel import policies on pricing behavior of firms and ii the interdependence of national parallel import policies if demand asymmetry across countries is sufficiently large the north forbids parallel imports to ensure its firm sells in the south thereby generating international price discrimination the south s most preferred market outcome as the equilibrium when demand structures are relatively similar across countries the north permits parallel imports and uniform pricing its most preferred market outcome obtains

regulatory environments and the location decision evidence from the early foreign market entries of new technology based firms new technology based firms ntbfs embarking on a strategy of rapid internationalisation choose foreign market entries that minimise transaction costs and the related risks of failure means to reduce the young firms vulnerability to the appropriation of intellectual capital are particularly important influences on early foreign market choices we explore the effect of the institutional dimension specifically the national regulatory environment on the location choices and the speed of internationalisation by british and german ntbfs we provide evidence that entrepreneurial young firms choose to enter country markets offering better regulatory protection for their intellectual property this decision is moderated by a home regulatory regime bias in contrast we observe that the speed of internationalisation is influenced less by the foreign regulatory regime and more by industry and firm characteristics we also observe that managerial experience influences the location choices of ntbfs facing regulatory hazards

stochastic dominance and mean variance measures of profit and loss for business planning and investment in this paper we first extend the stochastic dominance sd theory by introducing the first three orders of both ascending sd asd and descending sd dsd to decisions in business planning and investment to risk averse and risk loving decision makers so that they can compare both return and loss we provide investors with more tools for empirical analysis with which they can identify the first order asd and dsd prospects and discern arbitrage opportunities that could increase his her utility as well as wealth and set up a zero dollar portfolio to make huge profit our tools also enable investors and business planners to identify the third order asd and dsd prospects and make better choices to complement the stochastic dominance approach we also introduce an improved mean variance criterion to decisions in business planning or investment on both return and loss for risk averse and riskloving investors we then illustrate the superiority of the present approaches with well known examples in the literature and discuss the relationship between the improved stochastic dominance and mean variance criteria

unemployment institutions and reform complementarities re assessing the aggregate evidence for oecd countries there is no or limited consensus on the quantitative impact of institutions on unemployment which has led some to question the case for structural reforms recent studies suggest also that institutions interact with each other and cannot be analysed in isolation in this paper we estimate a standard reduced form model to explore the institutional determinants of unemployment and assess its robustness using a large battery of robustness checks we show that although the impact of each individual policy varies across countries due to policy interactions the simple linear model can be used to draw inferences for countries with an average mix of institutions the model is then extended to encompass systemic interactions in which individual policies interact with the overall institutional framework we find relatively robust evidence of broad reform complementarities

intellectual property rights and the governance of international r d partnerships this paper studies the degree to which country differences in intellectual property rights protection affect the choice of companies for a particular mode of international inter firm r d partnering it focuses on the preference of companies for either an equity joint venture or a contractual partnership we find that international differences in intellectual property rights protection are a significant factor with less secure protection firms choose r d joint ventures rather than contractual partnerships the level of technological change in industries has an inverse effect on the preference for international r d joint ventures

refunding noncallable debt that can benefit shareholders the substitution of new debt for old in a firm s capital structure in a situation in which the old bonds are selling at a premium over their par value but in which they are not callable the potential existence of such opportunities can be traced to the same tax laws that for a while made original issue discount bonds worth while in this case to the desirability of recog nizing in a timely fashion for tax purposes the real economic loss occasioned by having issued high coupon rate debt in what subsequently turns out to be a lowinterest rate environment

the multinational firm direct investment is incorporated into a simple general equilibrium model of international trade the analysis focuses on an attempt to endogenize the internalization decision it is argued that a reasonable approach assumes that arm s length contracts must be simple so that complex arrangements require internalization the model relates direct investment to the degree of underlying uncertainty and to fundamental trade determinants such as relative factor endowments the behavior of the model contrasts sharply with that of the markusen helpman model which takes internalization for granted

international stock market efficiency a non bayesian time varying model approach this article develops a non bayesian methodology to analyse the time varying structure of international linkages and market efficiency in g7 countries we consider a non bayesian time varying vector autoregressive tv var model and apply it to estimate the joint degree of market efficiency in the sense of fama 1970 1991 our empirical results provide a new perspective that the international linkages and market efficiency change over time and that their behaviours correspond well to historical events of the international financial system

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

the composition of foreign direct investment and protection of intellectual property rights evidence from transition economies while existing literature has examined the impact of intellectual property protection on the volume of foreign direct investment fdi little is known about its effect on the composition of fdi inflows the author addresses this question empirically using a unique firm level data set from eastern europe and the former soviet union she finds that weak protection deters foreign investors in technology intensive sectors that rely heavily on intellectual property rights the results also indicate that a weak intellectual property regime encourages investors to undertake projects focusing on distribution rather than local production the latter effect is present in all sectors not just those relying heavily on intellectual property protection

incomplete contracts and the product cycle the incomplete nature of contracts governing international transactions limits the extent to which the production process can be fragmented across borders in a dynamic general equilibrium ricardian model of north south trade the incompleteness of international contracts is shown to lead to the emergence of product cycles because of contractual frictions goods are initially manufactured in the north where product development takes place as the good matures and becomes more standardized the manufacturing stage of production is shifted to the south to benefit from lower wages following the property rights approach to the theory of the firm the same force that creates product cycles i e incomplete contracts opens the door to a parallel analysis of the determinants of the mode of organization the model gives rise to a new version of the product cycle in which manufacturing is shifted to the south first within firm boundaries and only at a later stage to independent firms in the south relative to a world with only arm s length transacting allowing for intrafirm production transfer by multinational fi rms is shown to accelerate the shift of production towards the south while having an ambiguous effect on relative wages the model delivers macroeconomic implications that complement the work of krugman 1979 as well as microeconomic implications consistent with the findings of the empirical literature on the product cycle

market reaction to quarterly earnings announcements a stochastic dominance based test of market efficiency the use of the capm in empirical research is subject to some criticism in light of this criticism the stochastic dominance criteria are offered as an alternative research method for the examination of market efficiency the underlying assumptions of the two frameworks are discussed and the stochastic dominance technique is demonstrated via the examination of market reaction to quarterly earnings announcements during the 24 quarters commencing with october 1962 the findings are compared to those of watts watts r the time series behavior of quarterly earnings unpublished paper university of newcastle newcastle n s w 1975 quoted in watts 1978 who utilized the same data base in contrast to watts conclusion our analysis suggests that the market was efficient during the entire period examined and that no significant differences in market behavior between the first and the second 12 month periods was evident the discord may be attributed to the relative effectiveness of the two analytical tool

determinants of patent rights a cross national study abstract this paper presents an index of patent rights for 110 countries for the period 1960 1990 the index is used to examine what factors or characteristics of economies determine how strongly patent rights will be protected the evidence does indicate that more developed economies tend to provide stronger protection but the underlying factors which influence patent protection levels are the country s level of research and development r d activity market environment and international integration which are correlated with its level of development the results qualify however that r d activity influences patent protection levels after a nation s research sector reaches a critical size an implication of this is that to raise patent protection levels in weakly protecting countries it is important to foster a significant research base in those countries and thereby create incentives for protecting patent rights

the boundaries of multinational enterprises and the theory of international trade this paper begins with a review of empirical evidence on multinational firms conceptual underpinnings of a theory are developed relying in particular on the notion of knowledge capital as a mobile joint input into geographically separated production facilities this idea is embedded in a simple two country general equilibrium model that supports multinational production in equilibrium under conditions consistent with the empirical evidence the final section examines internalization and shows why certain properties of knowledge capital also imply a preference for transferring technologies internally within the firm rather than through arm s length markets

which is a better investment choice in the hong kong residential property market a big or small property the relationship between property size and property investment yield is an interesting issue in the real estate market previous studies usually use the mean variance criterion to compare the return risk profiles of the yields of different property sizes in the united states however this criterion has a few shortcomings this article provides the first attempt to use a stochastic dominance approach to analyse this issue we adopt two powerful stochastic dominance tests to compare the yields of five property size classes in the hong kong residential property market in our study we analyse two possible investment outcomes 1 investors could not rent out their properties and thus they would gain lose from the appreciation depreciation of residential property prices 2 investors could also gain from rental incomes our empirical results provide strong evidence to show that the yields of smaller property classes stochastically dominate the yields of bigger property classes suggesting that buying smal

on the measurement of product variety in trade product variety plays an important role in the theoretical work on monopolistic competition and trade and recent empirical work has begun to quantify this for aggregate and disaggregate import demands the authors discuss the measurement of product variety in trade using a broad cross section of industrial and developing countries and disaggregating across sectors the authors calculate the export variety of countries in their sales to the united states and relate the export variety indexes to country productivities they confirm that countries with greater product variety in exports also have higher productivity this may be due to their development of and access to these products

licensee technological potential and exclusive rights in international licensing a multilevel model granting of exclusive rights is an important consideration for firms using licensing as a mode of entry into foreign markets as exclusive contracts reduce licensors flexibility in a given market during the term of the agreement by granting exclusivity to a licensee with greater technological potential the exchange partners can increase the potential transactional value of the licensing agreement at the same time a licensee with strong technological potential will increase the threat of transactional hazards due to underinvestment and rent appropriation in this paper we develop and empirically test a model that evaluates the balancing of transactional value and transaction costs in exclusive licensing in particular we identify the conditions under which exclusive contracts are likely to be granted to foreign licensees with strong technological potential empirical results from a multilevel model based on 375 international licensing agreements of us firms in high technology industries during 1995 2008 show that licensees with a stronger technological potential are more likely to be granted exclusive rights in countries with strong intellectual property rights protection and in industries with a high rate of technological change but are less likely to be granted exclusive rights when there is a high degree of overlap between licensor and licensee products

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

intellectual property rights licensing and innovation in an endogenous product cycle model abstract we develop a dynamic general equilibrium model of the product cycle to study the effects of stronger intellectual property rights iprs in the south on the incentives of firms in the north to innovate and to license advanced technologies innovation and licensing are random processes requiring resources stronger iprs increase the licensor s share of rents and reduce the costs of licensing contracts thus the returns to both licensing and innovation would rise while additional resources would be available for r d in consequence innovation and technology transfer would rise however the effect of stronger iprs on relative wages between regions is ambiguous

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

intellectual property rights and foreign direct investment abstract this paper develops a product cycle model with endogenous innovation imitation and foreign direct investment fdi we use this model to determine how stronger intellectual property rights ipr protection in the south affects innovation imitation and fdi we find that stronger ipr protection keeps multinationals safer from imitation but no more so than northern firms instead the increased difficulty of imitation generates resource wasting and imitation disincentive effects that reduce both fdi and innovation the greater resources absorbed in imitation crowd out fdi reduced fdi then transmits resource scarcity in the south back to the north and consequently contracts innovation

intellectual property rights foreign direct investment and industrial development this paper develops a north south product cycle model in which innovation imitation and the ow of fdi are all endogenously determined in the model a strengthening of ipr protection in the south reduces the rate of imitation and it increases the ow of fdi indeed

intellectual property protection and the industrial composition of multinational activity in a north south model with endogenous fdi we examine the impact of southern ipr protection on the mode and industrial composition of international technology transfer a novel feature of the model is that due to technological reasons industries differ with respect to their susceptibility to imitation in equilibrium licensing occurs in industries where the risk of imitation is low and fdi where it is of intermediate magnitude stronger iprs in the south i alter the industrial composition of multinational activity towards licensing at the expense of fdi ii reduce local imitation and iii increase licensing and to a lesser extent fdi

testing for weak form efficiency of crude palm oil spot and future markets new evidence from a garch unit root test with multiple structural breaks there is a sizeable literature that tests for weak form efficiency in commodity and energy spot and future prices while many studies now allow for multiple structural breaks to address the criticism that conventional unit root tests have low power to reject the unit root null in the presence of structural change the extant literature overlooks the fact that conventional unit root tests are biased in the presence of conditional heteroscedasticity we apply a recently developed generalized autoregressive conditional heteroscedasticity garch unit root test with multiple structural breaks to crude palm oil spot and future prices and find much more evidence against weak form efficiency than that found using tests that fail to allow for conditional heteroscedasticity our results point to the importance of allowing for heteroscedasticity when testing for efficiency in commodity and energy spot and future prices

pro market institutions and global strategy the pendulum of pro market reforms and reversals we review the literature analyzing the impact of pro market institutions on firms global strategy we propose that the ideological tension between whether the government or the market should drive economic development results in a pendulum of pro market reforms and reversals that drive changes in firm strategy and performance much progress has been made in the analyses of pro market reforms and their impact on firms international strategies and performance however there is a need to further learn about four areas 1 the concept of pro market institutions in particular the variety of institutional dimensions the measures and the influence of informal institutions on firm strategies 2 the drivers of changes in pro market institutions especially firms influences and the co evolution of firm strategies and institutional changes 3 the implications of changes in pro market reforms for the interactions among integration diversification and internationalization strategies the causality chains connecting institutions and strategies and the reconfiguration of activities globally and 4 the non traditional moderators that alter the impact of pro market institutional dynamics on firms strategies such as country level political systems industry level competitor reactions and individual level managerial capabilities and perceptions

technology transfer under asymmetric information licensing contracts for newly patented innovations are observed to vary along several dimensions including the form and size of the payment to the inventor fixedfee versus some output based royalty the degree of exclusivity and the division of rents in this article we show that theform of the contract can be explained by two problems in technology exchange the superiority of a licensor s precontractual information about the economic value of the innovation and thefact that sharing this information with the licensee mayfacilitate imitation we show that a licensor signals her technology type with an output based payment or royalty and may leave some of the rents with the licensee conditions under which exclusive license contracts linear and nonlinear and nonexclusive linear contracts are used to transfer technology are identified

a multistage linear stochastic programming model for optimal corporate debt management abstract large corporations fund their capital and operational expenses by issuing bonds with a variety of indexations denominations maturities and amortization schedules we propose a multistage linear stochastic programming model that optimizes bond issuance by minimizing the mean funding cost while keeping leverage under control and insolvency risk at an acceptable level the funding requirements are determined by a fixed investment schedule with uncertain cash flows candidate bonds are described in a detailed and realistic manner a specific scenario tree structure guarantees computational tractability even for long horizon problems based on a simplified example we present a sensitivity analysis of the first stage solution and the stochastic efficient frontier of the mean risk trade off a realistic exercise stresses the importance of controlling leverage based on the proposed model a financial planning tool has been implemented and deployed for brazilian oil company petrobras

a stochastic dominance analysis of yen carry trades abstract yen carry trades have made headline news for over a decade we examine the profitability of such trades for the period 2001 2009 yen carry trades generated high mean returns and sharpe ratios prior to the recent financial crisis they continued to outperform major stock markets for the full sample period given the non normality of carry trade returns we apply non parametric tests based on stochastic dominance sd to evaluate whether the high returns of yen carry trades are compatible with risk as reflected in returns on us and global stock market indices we apply a general test for sd developed recently by linton maasoumi and whang 2005 to six currencies as well as portfolios of these currencies for a large class of risk averse investors profits from yen carry trades cannot be attributed to risks

the measurement of intellectual property rights protection this research improves upon empirical studies that examine the measurement of intellectual property rights ipr protection prior measures examine only one type of law or lack a component that addresses the actual enforcement of these laws the measure presented here uses three types of ipr laws and enforcement components for them

the relationship between arbitrage and first order stochastic dominance this paper joins together two fields of research in financial economics the first field studies stochastic dominance while the second field studies arbitrage pricing the two fields are linked together through the derivation and the proof of a characterization theorem the characterization theorem gives necessary and sufficient conditions for the existence of arbitrage opportunities in terms of the existence of two assets one of which first order stochastically dominates the other and the price of a particular contingent claim examples are provided to demonstrate the theorem s content this paper joins together two fields of research in financial economics the first field studies portfolio choice from the perspective of stochastic dominance see hadar and russell 5 6 hanoch and levy 7 levy and kroll 13 the second field studies arbitrage pricing its characterization and implications see ross 15 kreps 12 harrison and kreps 8 harrison and pliska 9 in these fields it is well known that the existence of arbitrage opportunities implies first order stochastic dominance and that the converse does not hold this paper provides a set of conditions under which the converse is true given complete markets the existence of an arbitrage opportunity is characterized in terms of the existence of two traded assets one of which stochastically dominates the other along with one additional condition the additional condition is roughly that state contingent prices must be zero over the states where the first asset dominates the second the theorem has a qualification however it is applicable only in markets which are complete not in the arrow debreu sense but in a weaker sense in the sense that all contingent claims on the primary assets must trade in many applications especially with respect to continuous trading models this condition is usually satisfied see duffie 2 and harrison and pliska 9 in the case of stochastically dominated assets this paper shows that the relationship of the assets to the state contingent prices is important in identifying arbitrage opportunities in this sense this paper is related to a recent paper of jagannathan 10 jagannathan studies the relationship of second order stochastic dominance not first order to call option valuation this characterization theorem relating arbitrage opportunities to stochastic dominance should provide a valuable tool in the area of stochastic dominance this theorem specifies conditions under which two assets can be compared using first order stochastic dominance on an individual basis for inclusion in the

efficiency tests in the french derivatives market abstract the french derivatives market the marche a terme international de france matif or the french international futures and options exchange is one of the major derivatives markets in the world the efficiency of four financial contracts traded on the matif cac40 index futures ecu bond futures national bond futures and pibor 3 month futures are examined in this paper test results from serial correlations unit root tests and variance ratio tests provide overwhelming evidence that the random walk hypothesis cannot be rejected for these contracts

could the global financial crisis improve the performance of the g7 stocks markets abstractfinancial crises are normally associated with negative effects on financial markets in this article we investigate whether the most recent global financial crisis gfc had any positive impact on the g7 canada france germany italy japan the united kingdom and the united states indices to conduct the analysis we employ the mean variance mv analysis capm statistics hurst exponent runs test multiple variation ratio test and stochastic dominance sd tests our mv and capm results conclude that most of the g7 stock indices are significantly less volatile the results from hurst exponent run tests and multiple variation ratio confirm that efficiency improved in the post gfc period finally our sd results conclude that there is no arbitrage opportunity and the markets are efficient due to the gfc and in general investors prefer investing in the indices after the gfc overall we conclude that the gfc led to markets that are more efficient and mature confirming that crises can also

macroeconomic shocks and stock market returns the case of korea abstractthis study examines the effects of macroeconomic shocks on key macro variables including stock market returns in korea using the structural vector autoregression svar model we suggest a three variable svar model incorporating inflation output growth and stock returns we adopt a nonzero z ratio restriction for the long run identifying assumption to allow for economically meaningful relationships among variables while our results support the negative positive relation of demand supply shocks to stock returns we also find that demand shocks influence stock market variance more significantly than supply shocks do the sub period analysis finds that global market fluctuations during the global financial crisis have relatively little effect on korean stock market performance we also examine a generalized five variable model that includes the foreign exchange rate and interest rate confirming the results from the three variable case

imitation costs and patents an empirical study it has long been recognised that the costs of imitating new products have an important effect on the incentives for innovation in a market economy as arrow i962 and others have pointed out if firms can imitate an innovation at a cost that is substantially below the cost to the innovator of developing the innovation there may be little or no incentive for the innovator to carry out the innovation in their discussions of the innovation process economists frequently have called attention to the major role played by the costs of imitation but there has been little or no attempt to measure these costs to test various hypotheses concerning the factors influencing them or to estimate their effects in this paper we report some findings of what seems to be the first study of this topic in addition we present data regarding the effects of patents on imitation costs and on the rate of innovation

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

corporate debt management and the value of the firm three alternative characterizations of corporate debt management policy which have had wide currency in the literature are examined they are shown to give rise to substantial differences in their predictions of total firm value this study concludes that of the three the one that assumes that management periodically rebalances the firm s debt levels in response to evolving new information on expected future operating cash flows is the most logically consistent on that basis a reinterpretation of the available empirical evidence on the tax effect of debt is indicated

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 impact of patent rights on international trade evidence from canada the extent to which canadian manufacturing exports are sensitive to national differences in patent rights are examined the conclusion is that overall canadians tend to export more to those countries where their patent rights are highly safeguarded stronger patent protection induces canadians to export relatively more to high income countries than to low income countries in addition the effect of stronger patent rights is to increase exports to those countries that pose a strong threat of imitation and to reduce exports to those countries that pose the weakest threat of imitation jel classification f13 o34 impact de la propriete des brevets sur le commerce international resultats pour le canada ce memoire examine jusqu a quel point les exportations manufacturieres canadiennes sont sensibles aux differences dans la propriete des brevets entre pays l etude conclut que les canadiens tendent a exporter davantage vers les pays ou la propriete des brevets est hautement protegee il appert que la plus forte protection de la propriete des brevets tend a faire que les canadiens exportent relativement plus vers les pays a hauts revenus que vers ceux a plus faibles revenus de plus il appert que l effet de la plus forte protection des brevets est d accroitre les exportations vers les pays qui posent une forte menace d imitation et de reduire les exportations vers les pays qui posent la plus faible menace d imitation

on the matter of parity among financial obligations the lessons of the leasing literature concerning the impact of leases on the debt capacity of a firm are reviewed and summarized to establish an approach to the analysis of the corporate bond refunding decision a general proposition regarding financial obligation parity is established and from that a clear bond refunding decision rule is developed previous debates in the literature about appropriate discount rates and about the appropriate cash flows to be discounted for refunding decisions are clarified the debate in the finance literature during the last decade about the proper approach to the corporate asset leasing decision has given rise to a number of useful insights into issues relating to debt capacity and the valuation of income streams having different risk characteristics indeed the debate turns out to have much in common with the u s space program of the preceding decade in that the technological spin offs resulting from the effort were often as significant as the attainment of the original objective itself our purposes in the present paper are twofold and they are addressed in sequence below first we shall offer what we believe to be some needed additional clarifying observations on the nature of the most recently proposed approaches to the evaluation of lease contracts second we shall extend the lessons derived from the analysis to develop a further important technological spin off the latter has to do with corporate bond refunding decisions in particular the notion of parity among alternative financial obligations which we shall see is central to a proper appraisal of asset leasing arrangements also provides the key to a resolution of the longstanding refunding controversy

valuation and hedging of risky lease payments presented here is a simple formula to value risky corporate lease payments when the amount of debt displaced by a lease depends on the value of the lease the displaced debt tax shields are risky the value of these risky tax shields is less than the value of riskless tax shields the valuation of the lease makes use of a dynamic investment strategy that replicates the lease payments and associated tax shields from displaced debt a useful variation of the valuation formula requires only the contractual cash flows and the yield on lease equivalent debt calculations show that the new formula can produce significantly different lease values from formulas that assume riskless cash flows

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

refunding discounted debt a clarifying analysis this paper demonstrates that refunding discounted debt represents a form of tax arbitrage that is profitable to taxpaying corporations when the present value of the additional tax shields created through the refunding exceeds the sum of the present value of the overall increase in pre tax debt service requirements after tax transaction costs and any tax in curred on the gain the paper contrasts the factors that give rise to profitable opportunities to refund high coupon debt and discounted debt it also shows that of the analytical ap proaches previously suggested for calculating the net advantage of refunding discounted debt discounting the change in after tax debt service payments at the after tax cost of money for the refunding issue is the only one consistent with preserving debt service parity

convergence of the south and non south income distributions 1969 1979 income distribution and inequalities in the southern united states are analyzed and compared with data for the rest of the country the evidence presented in this paper reveals that in the 1970s the souths income distribution either converged or moved significantly closer to the income distribution of the rest of the country the degree of convergence depends on the definition of the recipient unit and to a degree on the particular cost of living index used to deflate southern and non southern incomes the convergence is attributed in part to the labor unionization in the northeast and the resulting relocation of companies to the south data are from the 1970 and 1980 censuses and concern total household income excerpt

market response to policy initiatives during the global financial crisis abstract this paper examines the impact of macroeconomic and financial sector policy announcements in the united states the united kingdom the euro area and japan on interbank credit and liquidity risk premia during the recent crisis overall policy interventions were associated with a reduction in interbank risk premia most significantly for recapitalization programs by contrast decisions to bail out individual banks in an ad hoc manner or let them fail were accompanied by a significant rise in interbank risk premia most policy announcements had international spillovers these results are broadly robust to using alternative measures of financial distress and varying the size of the event window

international protection of intellectual property we study the incentives that governments have to protect intellectual property in a trading world economy we consider a world economy with ongoing innovation in two countries that differ in market size and in their capacities for innovation after describing the determination of national patent policies in a non cooperative regime of patent protection we ask why is intellectual property better protected in the north than in the south we also study international patent agreements by deriving the properties of an efficient global regime of patent protection and asking whether harmonization of patent policies is necessary or sufficient for global efficiency jel o34 f13 during the 1980 s and early 1990 s the united states and several european countries expressed strong dissatisfaction with what they deemed to be inadequate protection of intellectual property in many developing countries the developed countries made the upgrading of intellectual property rights iprs one of their highest priorities for the uruguay round of trade talks their efforts bore fruit in the agreement on traderelated aspects of intellectual property rights trips which was approved as part of the final act of the uruguay round trips establishes minimum standards of protection for several categories of intellectual property for example in the area of new technology it essentially harmonizes

market efficiency of oil spot and futures a mean variance and stochastic dominance approach this paper examines the market efficiency of oil spot and futures prices by using both mean variance mv and stochastic dominance sd approaches based on the west texas intermediate crude oil data for the sample period 1989 2008 we find no evidence of any mv and sd relationships between oil spot and futures indices this infers that there is no arbitrage opportunity between these two markets spot and futures do not dominate one another investors are indifferent to investing spot or futures and the spot and futures oil markets are efficient and rational the empirical findings are robust to each sub period before and after the crises for different crises and also to portfolio diversification

an institution based view of global ipr history leveraging the use of history to advance international business research this article focuses on the crucial debate over intellectual property rights ipr between the united states and china ironically during the 19th century the united states was not a leading ipr advocate as it is today but was a leading ipr violator developing an institution based view of ipr history we identify three underlying theoretical mechanisms that help to explain ipr in the two countries path dependence long term processes and institutional transitions we argue that both the us refusal to protect foreign ipr in the 19th century and the current chinese lack of enthusiasm to meet us ipr demands embody rational responses to their respective situations however given long term processes with intensifying isomorphic pressures institutional transitions in favor of better ipr protection are quite possible finally going above and beyond these two countries we draw on the ipr history in over ten other countries to develop a more globally generalizable framework which in turn contributes to the key question of how history matters

contracts intellectual property rights and multinational investment in developing countries abstract the policy debate between multinational firms favoring strong contract law and host country governments who often oppose such protection motivates the paper local agents managers learn the multinational s technology and can defect to start a rival firm contract enforcement including binding the multinational itself makes the multinational better off outcomes for the host country are more complex depending on mode switches induced by enforcement if enforcement induces the multinational to switch from exporting to local production welfare improves if local production was occurring anyway enforcement may result in the loss of rents to local agents and lower welfare

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

intellectual property rights product complexity and the organization of multinational firms this paper studies how the intellectual property right ipr regime in destination countries influences the way multinationals structure the international organization of their production in particular we explore how multinationals divide tasks of dierent complexities across countries with dierent levels of ipr protection the analysis studies the decision of firms between procurement from related parties and outsourcing to independents suppliers at the product level it also breaks down outsourcing into two types by distinguishing whether or not they involve technology sharing between the two parties we combine data from a french firm level survey on the mode choice for each transaction with a newly developed complexity measure at the product level our results confirm that firms are generally reluctant to source highly complex goods from outside firm boundaries by studying the interaction between product complexity and the ipr protection we obtain that i for technology sharing outsourcing iprs promote outsourcing of more complex goods to a destination country by guaranteeing the protection of their technology ii for non technology related outsourcing iprs attract the outsourcing of less complex products that are more prone to reverse engineering and simpler to decodify and imitate

licensing versus direct investment implications for economic growth we develop a symmetric two country model of foreign direct investment fdi that captures the internalization decision and its implications for both the rate and magnitude of innovations when mode choice licensing versus fdi is fixed a subsidy to multinational production increases the rate but decreases the size of innovations when mode can switch the rate and size of innovations both increase provided the subsidy is not too large although innovation size decreases for industries where firms already were choosing fdi innovation size increases for industries where firms switch from licensing to fdi because multinationals choose larger innovations than licensors 2002 elsevier science b v all rights reserved

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
