the paradox of openness revisited collaborative innovation and patenting by uk innovators we revisit the paradox of openness in the literature which consists of two conflicting views on the link between patenting and open innovation the spillover prevention and the organizational openness views we use the data from the survey of innovation and patent use and the community innovation survey cis6 in the uk to assess the empirical support for the distinct predictions of these theories we argue that both patenting and external sourcing openness are jointly determined decisions made by firms their relationship is contingent upon whether the firms are technically superior to their rivals and lead in the market or not leading firms are more vulnerable to unintended knowledge spillovers during collaboration as compared to followers and consequently the increase in patenting due to openness is higher for leaders than for followers we develop a simple framework that allows us to formally derive the empirical implications of this hypothesis and test it by estimating whether the reduced form relationship between patenting and collaboration is stronger for leaders than for followers

what determines bits abstract similar to bilateral or regional preferential trade agreements ptas bilateral investment treaties bits have proliferated over the past 50 years the purpose of this study is to provide the first systematic empirical analysis of the economic determinants of bits and of the likelihood of bits between pairs of countries using a qualitative choice model in a manner consistent with explaining ptas we develop the econometric specification for explaining the two based upon a general equilibrium model of world trade and foreign direct investment with three factors two products and trade and investment costs among multiple countries in the presence of national and multinational firms the empirical model for bits and ptas is bivariate in nature and supports a set of hypotheses drawn from the general equilibrium model using the preferred empirical model for a sample of 12 880 country pairs in the year 2000 we predict correctly 88 of all pairs with a bit and a pta 81 with a bit but no pta and 84 with a pta but no bit

specialized supply firms property rights and firm boundaries the proper specification of intellectual property rights iprs is a delicate and controversial matter in this paper we consider one specialized context in which iprs can add to efficiency we build on contributions of both firm capabilities scholars e g teece pisano et al and property rights economists e g hart to show that iprs can affect efficiency by influencing the location of technological innovation using a simple set up where the key choice is whether a technology intensive input will be supplied by an independent firm or produced in house we analyze how the choice is affected by the strength of iprs and by the existence and nature of information spillovers specifically we show that when the supply relationship is likely to produce new information of value to the supplier stronger property rights favor independent suppliers over vertical integration an important implication of our model backed by empirical case studies is that strong iprs therefore encourage investments in specialized firms with strong firm capabilities in the area of innovative input supply iprs therefore may play a role along with multiple other factors in the location of firm boundaries in some cases this contribution to the viability of small specialized firms with their superior ability to innovate in some cases must be taken into account in evaluating recent criticisms of over fragmented ipr ownership i e the anticommons problem it also contributes to an understanding of iprs in the post chandlerian economy where smaller specialized firms play a prominent role copyright 2004 oxford university press

pigou meets mirrlees on the irrelevance of tax distortions for the second best pigouvian tax this paper extends the mirrlees 1971 model of optimal income redistribution with optimal corrective taxes to internalize consumption externalities using general utility structures and exploring both linear and non linear taxes it is demonstrated that the optimal second best tax on an externality generating good should not be corrected for the marginal cost of public funds since it equals one in the optimal tax system in the optimum distortions of income taxes are equal to marginal redistributional gains if the government does not have access to a non distortionary marginal source of finance the marginal cost of public funds can be either larger or smaller than one depending on subjective preferences for income redistribution the optimal second best corrective tax is then either higher or lower than the pigouvian level the findings in this paper generalize and amend prior results based on representative agent models shedding new light on the weak double dividend hypothesis and on the welfare gains of recycling revenue from environmental taxes

optimal redistribution and monitoring of labor supply this paper extends the mirrlees 1971 model of optimal non linear income taxation with a monitoring technology that allows the government to verify labor supply at a positive but non infinite cost we analyze the joint determination of the non linear monitoring and tax schedules and the conditions under which these can be implemented monitoring of labor supply reduces the distortions created by income taxation and raises optimal marginal tax rates possibly above 100 the optimal intensity of monitoring increases with the marginal tax rate and the labor supply elasticity our simulations demonstrate that monitoring strongly alleviates the trade off between equity and efficiency welfare gains of monitoring are around 2 8 of total output the optimal intensity of monitoring follows a u shaped pattern similar to that of optimal marginal tax rates our paper can explain why large welfare states optimally rely on work dependent tax credits active labor market policies benefit sanctions and work bonuses in welfare programs

fairness self interest and the politics of the progressive income tax all advanced democracies have adopted income taxes with considerable progression in marginal tax rates to explain this we examine the nature of individual and collective preferences over alternative tax schedules in the context of a simple two sector model we first consider the case of altruistic or sociotropic citizens who view the income tax as a means of achieving a fairer or more egalitarian distribution of income we show that greater marginal rate progressivity may well be less fair that a fairest tax however defined is always a linear or flat rate schedule in which all incomes are taxed at the same marginal rate and that with a purely sociotropic electorate there exists a flat rate schedule which is a majority equilibrium we then show that with self interested voters who seek to minimize their own tax burdens greater marginal rate progression may well be preferred by middle and upper income voters that for middle income citizens the optimal schedule is a sharply progressive one and that within the set of individually optimal schedules there exists a majority equilibrium which is a progressive schedule which minimizes the burden on median income or middle class citizens at the expense of lower and upper income taxpayers

taking versus taxing an analysis of conscription in a private information economy most countries currently man their militaries through conscription i e a draft conventional wisdom suggests that by lowering the budgetary cost of the military a draft reduces distortionary taxation especially when military needs are large we find that this intuition is misguided when income taxes are set optimally voluntary enlistments lead to less distortionary taxation than a draft because the tax base left behind by a volunteer army tends to be more productive than that after a draft for reasonable parameter values drafts are more distortionary and less socially desirable when military needs are large

on the sign of the optimum marginal income tax this paper studies a central aspect of optimal income taxation as modelled in mirrlees original paper on the topic identical leisure consumption preferences qualitatively homogeneous skills in production namely whether given concave utilitarianism alone the optimal marginal income tax will be non negative a well known positive answer to this question in weak inequality form was given in the said paper which however we show requires additive separability of individual utility in the ordinal and cardinal senses our main result here is to derive the required strict positivity of the marginal tax under weak conditions slightly wider than noninferiority of consumption and leisure with preferences otherwise arbitrary

optimal social insurance with linear income taxation we study optimal social insurance aimed at insuring disability risk in the presence of linear income taxation optimal disability insurance benefits rise with previous earnings optimal insurance is incomplete even though disability risks are exogenous and verifiable so that moral hazard in disability insurance is absent imperfect insurance is optimal because it encourages workers to insure themselves against disability by working and saving more thereby alleviating the distortionary impact of the redistributive income tax on labor supply and savings

using elasticities to derive optimal income tax rates this paper derives optimal income tax formulas using compensated and uncompensated elasticities of earnings with respect to tax rates a simple formula for the high income optimal tax rate is obtained as a function of these elasticities and the thickness of the top tail of the income distribution in the general non linear income tax problem this method using elasticities shows precisely how the different economic effects come into play and which are the key relevant parameters in the optimal income tax formulas of mirrlees the optimal non linear tax rate formulas are expressed in terms of elasticities and the shape of the income distribution these formulas are implemented numerically using empirical earning distributions and a range of realistic elasticity parameters

on the optimal income taxation and educational decisions abstract in this paper we consider three different ways of incorporating individuals educational choices into the design of optimal income tax policy in one variant of the model case 2 where an individual chooses his education before knowing his ability and after that education makes his labour supply decisions on the basis of known ability it is shown that qualitative features of the optimal income tax schedule are not similar to those of the standard optimal income tax model the marginal tax rate is generally not zero at the endpoints of distribution but is most likely negative using numerical methods some interesting features quite different from earlier numerical results are revealed especially in the second case for example the marginal tax rate is non decreasing in income for a substantial income range in addition our calculations support neither the traditional views on the egalitarian nature of equal education nor its disadvantageous consequences in the perfect utilitarian society

james mirrlees contributions to the theory of information and incentives the theory of information and incentives has revolutionized economics we now understand how markets and other modes of private economic transaction as well as public policy are affected when different participants have different information or when the actions of some participants are not observable to others mirrlees has made pathbreaking contributions arguably the two most important contributions to the development of these ideas and methods of analysis his review of economic studies article 1971c on optimal nonlinear income taxation introduced a technique that evolved into the revelation principle which fully characterizes all policies that are incentive compatible or feasible under information asymmetry this technique is now the workhorse model for numerous applications his bell joumal of economics article 1976a on hierarchies and organizations and some of his important unpublished yet widely circulated papers referred to below played a similar role for the theory of the design of incentives to induce effort he identified the precise way in which observable outcomes convey probabilistic information about the underlying unobservable action and thereby clarified how rewards or punishments based on outcomes can serve as incentives to action mirrlees developed these ideas in the context of specific applications however they are truly fundamental to economic theory and they have profoundly influenced subsequent thinking and research on the design of

altruism jealousy and the theory of optimal non linear taxation abstract this paper studies optimal non linear taxes in a world in which there is altruism and jealousy a formula for optimal marginal tax rates is derived which turns out to be a simple and intuitively appealing extension of a result due to mirrlees the paper shows that in this sort of economy all of optimal tax theory s general results either no longer hold or need not hold and it sets out appropriate modifications to standard tax rules

top marginal taxation and economic growth abstractthe article explores the relationship between top marginal tax rates on personal income and economic growth using a data set of consistently measured top marginal tax rates for a panel of

the income and tax share of very high income households 1960 1995 this paper presents new information on the fraction of adjusted gross income and of wages and salaries that is reported by taxpayers in the top one half of one percent of the income distribution this corresponds to roughly five hundred thousand households in the late 1990s this paper relies on data from the treasury s individual income tax model for the period 1960 1995 the definition of adjusted gross income is standardized so that changes in the tax law do not affect the measured concentration of agi the results suggest that the share of agi reported by the highest income households increased significantly between the early 1980s and the mid 1990s with most of the increase taking place in the years immediately following the tax reform act of 1986 while we find some evidence of transitory changes in the concentration of income around major tax changes which may be the result of income retiming by high income taxpayers re timing does not seem to explain most of the changes since 1986 this abstract was borrowed from another version of this item

multinationals and corporate social responsibility in host countries does distance matter prior studies have found that foreign affiliates of multinational enterprises mnes suffer from liability of foreignness lof foreign affiliates may be able to improve their social legitimacy and overcome lof by demonstrating social commitment to host country constituents through corporate social responsibility csr if lof is positively related to the distance between the home and host countries and csr activities confer social legitimacy benefits on foreign affiliates we should expect csr activities and distance to be positively related however we argue that despite this potential motivation foreign affiliates from more distant home countries are in fact less likely to engage in host country csr our argument focuses on the ways in which distance affects the mne s willingness and ability to engage in csr abroad we also predict that host country csr reputation negatively moderates this relationship using community reinvestment act data for foreign bank affiliates from 32 countries in the united states over 1990 2007 we find strong support for our hypotheses the paper enriches our understanding of csr practices in mnes and of when and how mnes try to overcome legitimacy issues in host countries

impact of environmental regulations on trade in the main eu countries conflict or synergy in an increasingly integrated world with declining trade barriers environmental regulations can have a decisive role in shaping countries comparative advantages the conventional wisdom about environmental protection is that it comes at an additional cost on firms imposed by the government which may erode their global competitiveness however this paradigm has been challenged by some analysts in particular porter 1991 and porter and van der linde 1995 argue that pollution is often associated with a waste of resources and that more stringent environmental policies can stimulate innovations that may over compensate for the costs of complying with these policies this is known as the porter hypothesis while there is a broad empirical literature on the impact of trade on environment the empirical literature on the impact of environmental regulations on trade flows is relatively scarce very heterogeneous and presents mixed results the innovative feature of this paper is its attempts to estimate in a gravity setting augmented with a proxi of environmental stringency the impact of three major multilateral environmental agreements meas on 15 eu countries bilateral exports according to our estimates in the period 1988 2008 to be member of meas had a positive average impact on eu15 bilateral exports this evidence can be partly explained by a possible trade diversion effect with respect to countries that did not sign meas and a corresponding trade creation effect among members of the environmental agreements furthermore evidence coming from interaction effects estimates seems to show that for exporting countries having signed the unfccc and the montreal agreements partly mitigates by the amount of the estimated coefficient the negative impact of having a relatively more stringent environmental regulation on bilateral trade this result could have important policy implications for the future international trade environmental negotiations

distance trade and fdi a hausman taylor sur approach this paper analyses the effects of distance as a common determinant of exports and fdi in a three factor new trade theory model assuming that distance affects both pure trade costs and plant set up costs exports and fdi are not necessarily substitutes with respect to distance since the predicted impact depends on its importance for fixed plant set up costs relative to transportation costs and on the relative importance of vertical mnes for the empirical specification we suggest that the impact of time invariant variables such as distance is most appropriately analysed in a hausman taylor sur model we apply our model to industry level data of bilateral outward fdi stocks and exports of the us and germany copyright 2004 john wiley sons ltd

how far away is an intangible services fdi and distance foreign direct investment fdi in services has grown significantly in recent years evidence of spatial relationships in fdi decisions have been provided for goods manufacturing by utilising physical distance based measures of trade costs this paper investigates spatial interactions for services fdi using several distance measures including physical distance genetic distance and transport time across different measures of distance the traditional determinants of outbound fdi activity remain valid for services we also find spatial interdependence for services fdi that is generally supportive of export platform fdi

optimal linear income taxation with general equilibrium effects on wages abstract the paper argues that the endogeneity of wages may make a considerable difference to optimal linear tax rates in this case there is not only the usual direct redistribution via the fiscal system but also the general equilibrium redistribution due to the change in wages depending on the elasticity of substitution of the production function and the labour supply elasticities these may be reinforcing or opposing it is shown that the general equilibrium effect may plausibly outweigh the direct effect so that net redistribution to the lower paid involves a wage subsidy financed by a lump sum tax

optimum taxation with errors in administration abstract the paper compares the welfare levels which can be achieved by two distinct tax regimes lump sum taxation where one attempts to identify individuals and allocate transfers or subsidies on the basis of characteristics and income taxation where characteristics are not observed but personal incomes are measured and taxed where there are no errors in classifying individuals lump sum taxation is superior but where mistakes are made in the allocation of lump sum grants or subsidies income taxation may be more attractive the level of errors where the regimes are equally desirable in terms of social welfare is computed in simple models following that of feldstein 1973 where there is strong aversion to inequality then income taxation becomes preferable at quite small errors in analysing income taxation it is shown that in the feldstein model with endogenous wages the marginal tax rate in optimum income taxation on the more skilled is negative and that on the less skilled is positive in contrast to the standard results see seade 1977 with exogenous wages

the efficient side of progressive income taxation abstract this paper examines allocative properties of progressive income taxation when individuals care about their relative income it shows that introducing a progressive income tax can yield a pareto improvement if pre tax income is evenly distributed implementing undistorted choices of working hours requires a progressive tax schedule and the optimal degree of progressivity decreases with pre tax income inequality

ideas for rent an overview of markets for technology this article surveys some of the recent literature on technology markets and summarizes its main issues and insights we structure our analysis in three parts the supply and demand of technology the factors that condition the formation and growth of technology markets industry structure and dynamic issues in addition we summarize some of the studies that have tried to document the size and growth of these markets we find that the literature has focused mainly on the supply of technology but several other aspects of these markets remain under studied including the demand for external technology the role of uncertainty in technology markets and the dynamic interaction between industry structure and the market for technology understanding these will illuminate whether markets for technology will continue to grow or remained confined to pockets of the economy copyright 2010 the author 2010 published by oxford university press on behalf of associazione icc all rights reserved oxford university press

on the optimal income taxation some further numerical results abstract using numerical calculations we show in the optimal income tax model that a realistic value for the elasticity of substitution between consumption and leisure 0 5 leads to conclusions different from some of those drawn by mirrlees 1971 and atkinson 1973 the marginal tax rates are not so low and the shape of the tax schedule is for a great majority of the population substantially nonlinear a new feature in our calculations is that both results come out without going to maximin as done by atkinson 1973 we study in special cases the locality of the zero limit of the marginal tax rate at the upper end of the ability distribution and we achieve a very definite conclusion this result is really very local we also present an interesting approximation result concerning the relationship between the level of the government revenue and the marginal tax rate for individuals with high ability an important methodological remark analogous to sen s critique on the ethical measures of inequality is made on the interpretation of optimal income tax calculations

knowledge capital international trade and foreign direct investment a sectoral analysis the knowledge capital kc model of mnes is now a widely adopted empirical approach to explaining the location and production decisions of global firms based on both horizontal and vertical motivations while most of the existing studies have focused on highly aggregated national data we extend this model to sectoral data consisting of broad manufacturing industries and explicitly account for the dynamic nature of international investment data the empirical results from a dynamic panel data analysis indicate that that the predictions of the kc model regarding mne behavior vary by the type of industry production processes in electronics and transportation equipment are more characterized by efficient vertical specialization of r d activities and assembly while other sectors display more complex motivations

optimal top marginal tax rates under income splitting for couples abstract this paper provides formulas for optimal top marginal tax rates when couples are taxed according to income splitting between spouses consumption is taxed and the skill distribution is unbounded optimal top marginal income tax rates are computed for germany using a dataset that includes the tax returns of all german top taxpayers we find that the optimal top marginal tax rate converges to about 2 3 and convergence obtains at income levels that are substantially higher than those currently subject to the actual top tax rate

optimal income taxation an example with a u shaped pattern of optimal marginal tax rates comment using the mirrlees optimal income tax model with quasi linear preferences the paper examines conditions for marginal tax rates to be rising at high income levels and declining in an interval containing the modal skill it examines conditions for the marginal tax rate to be higher at a low skill level than at the high skill level with the same density an argument only holding for skill levels above a cutoff where resources of a worker are marginally of the same value as resources of the government data on earnings rates are presented copyright 1998 by american economic association

foreign direct investment and european integration in the 1990s this paper examines the effects of eu integration in the 1990s on the fdi relations in europe we find that the completion of the single market the 1995 enlargement and the so called eastern enlargement are characterised by a substantial positive anticipation effect in the period between the announcement and the formal establishment of each integration step neither the single market programme nor the previous enlargement exhibited any further positive effects on intra eu fdi volumes after their establishment

optimal degree of progressivity under income uncertainty the insurance effect is introduced into the design of the optimal income tax policy when individual income is uncertain one of the most noteworthy aspects of this analysis is that now it is even more difficult to derive analytically useful results for income tax policy purposes than it was in earlier analyses using numerical methods it is shown that under quite reasonable assumptions regarding utility function and income distribution we obtain a progressive marginal tax rate structure which is rather similar to the structures actually observed in many countries

the elasticity of taxable income with respect to marginal tax rates a critical review this paper critically surveys the large and growing literature estimating the elasticity of taxable income with respect to marginal tax rates using tax return data first we provide a theoretical framework showing under what assumptions this elasticity can be used as a sufficient statistic for efficiency and optimal tax analysis we discuss what other parameters should be estimated when the elasticity is not a sufficient statistic second we discuss conceptually the key issues that arise in the empirical estimation of the elasticity of taxable income using the example of the 1993 top individual income tax rate increase in the united states to illustrate those issues third we provide a critical discussion of selected empirical analyses of the elasticity of taxable income in light of the theoretical and empirical framework we laid out finally we discuss avenues for future research jel h24 h31 j22

on the contractual governance of research collaborations allocating control and intellectual property rights in the shadow of potential termination abstract this paper investigates the governance design problem of a large company that wants to engage a small and cashless firm into a research collaboration this analysis reflects the frequently observed collaborations between pharma companies and biotechs and an actual research contract is assessed to link theory to practice the governance form refers to the allocation of control rights over the research process and property rights over research output s as determined by the initial contract yet this contract is incomplete the parties negotiate at a later stage from bargaining positions that depend on the initial choice of the governance but they also contemplate the possibility that the collaboration will be terminated by means of a simple model that captures the core aspects of the contractual environment i answer a key research question how should governance be designed in the shadow of potential termination to provide the research firm with the incentives to invest in the collaboration first it is in the company s interest to choose a governance form that eliminates the possibility of termination and stabilizes the collaboration whenever possible second if the collaboration cannot be stabilized the company faces a trade off between reducing the probability of termination and providing incentives which is ultimately resolved by making the collaboration highly unstable third property rights and control are substitutes in the governance design if the company collects more property rights it must relinquish more control rights

tax progressivity income distribution and tax non compliance this article examines the determinants of tax non compliance when we recognise the existence of an imperfectly competitive tax advice industry supplying schemes which help taxpayers reduce their tax liability we apply a traditional industrial organisation framework to model the behaviour of this industry this tells us that an important factor determining the equilibrium price and hence the level of noncompliance is the convexity of the demand schedule we show that in this context this convexity is affected by the distribution of pre tax income the progressivity of the tax schedule and the way in which monitoring and penalties vary with income it is shown that lower pre tax income inequality as well as a less progressive tax code may cause more tax minimisation activities therefore the frequently advocated policy of reducing the highest tax rate may fail as a policy directed at improving tax discipline one way of offsetting the possible harm to tax compliance from a less progressive tax could be an adjustment of the penalty and monitoring functions

structural models of family labor supply a discrete choice approach a static neoclassical structural model is presented explaining labor supply of both spouses in two adult households in the netherlands family preferences are described with a direct translog utility function with the husbands leisure the wifes leisure and family income as its arguments we assume that the choice set of each family is finite account is taken of the dutch tax and benefits system we allow for hours restrictions and random preferences and account for unobserved wages of nonworkers the models are estimated using smooth simulated maximum likelihood results based upon dutch cross section data from 1987 are illustrated by confidence intervals for elasticities and by several policy simulations excerpt

technological flows and choice of joint ventures in technology alliances abstract this paper analyses the influence of technological flows in the choice of joint ventures as a governance form of technology alliances using a theoretical framework based on transaction costs economics and the economics of intellectual property rights we argue that the formation of a joint venture is only necessary in situations for which technological flows make the monitoring of alliance activities and the distribution of cooperation rents difficult our hypotheses have been confirmed using a sample of technology alliances created by companies from the european union between 1992 and 1999

taxation with representation abstract in this paper a framework is developed for the joint analysis of tax preparation mode and tax non compliance estimation is performed using micro level audit data from the internal revenue service although tha availability of tax practitioners undoubtedly reduces many of the informational and computational barriers to tax compliance the results indicate that their use particularly the use of cpas and attorneys is associated with increased tax non compliance which may have negative implications for both tax equity and tax efficiency

optimal income tax under the threat of migration by top income earners we examine how allowing individuals to emigrate to pay lower taxes changes the optimal nonlinear income tax scheme in a mirrleesian economy an individual emigrates if his domestic utility is less than his utility abroad net of migration costs utilities and costs both depending on productivity a simple formula that complements saez s formula obtained in closed economy is derived for the marginal tax rates faced by top income earners it depends on the labour elasticity the tax rate abroad and the migration costs expressed as a fraction of the utility obtained abroad the rawlsian marginal tax rates obtained for the whole population illustrate a curse of the middle skilled simulations are provided for the french economy

a reexamination of the optimal nonlinear income tax abstract this paper investigates mirrlees model of optimal income taxation it provides a concrete example of utility and density functions for which the solution to the usual first order model is not implementable i e and example where the first order approach does not work adding second order conditions leads to an extended model and to implementable solutions if these conditions are binding one gets a kink in the optimal net income schedule and bunching of individuals occurs the properties of an optimal nonlinear income tax are reexamined within the extended model

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

media capture in a democracy the role of wealth concentration abstract since objective news coverage is vital to democracy captured media can seriously distort collective decisions the current paper develops a voting model where citizens are uncertain about the welfare effects induced by alternative policy options and derive information about those effects from the mass media the media might however secretly collude with interest groups in order to influence the public opinion in the case of voting over the level of a productivity enhancing public bad it is shown that an increase in the concentration of firm ownership makes the occurrence of media bias more likely although media bias is not always welfare worsening conditions for it to raise welfare are restrictive

collaborative promotion of technology standards and the impact on innovation industry structure and organizational capabilities evidence from modern patent pools this study explores the impact of modern patent pools inter organizational collaborative arrangements for promoting the adoption of technology standards on the rate of follow on innovations based on pooled technologies the vertical structure of associated industries and organizational capabilities of noncollaborating firms on one hand the formation of modern pools can boost follow on innovation by lowering the search negotiation and licensing costs associated with pooled standards on the other hand modern pools may decrease the incentives to invest in follow on innovations because of cannibalization risks and grant back provisions to the extent that modern pools succeed in establishing a dominant standard their collaborative nature and their reliance on markets for technology can reduce technological uncertainty and appropriation hazards hence triggering vertical disintegration in related industries moreover by establishing a dominant standard modern pools can effectively diminish the relati

inherent inequality and the optimal graduation of marginal tax rates in most countries marginal tax rates increase with income this is at variance with the results of the optimal income taxation literature whose numerical calculations have established the presumption that optimal marginal tax rates should decline with income have the existing results of optimal income tax literature therefore established a presumption that the observed pattern is suboptimal the object of this paper is to attempt to answer this question the numerical calculations that followed mirrlees s 1971 pioneering contribution tried many variations on his basic parametrisation including different preference structures and different functional forms however so far as we are aware most of the reported results maintain his basic assumption of a log normal distribution of abilities or wages with a standard deviation of logs of 0 39 mirrlees 1971 himself appealed the work of lydall 1969 for this figure but it has become the industry standard we show in this paper that departures from this assumption in particular increases in inherent inequality can alter the qualitative pattern of optimal marginal tax rates dramatically contrary to the currently available calculations we show that the optimal graduation can indeed be such that marginal tax rates increase for the majority of the population which is consistent with the observed pattern but that there continues to exist a significant income range at the top where marginal tax rates decline which of course is counter to the observed pattern

tax avoidance and the deadweight loss of the income tax traditional analyses of the income tax greatly underestimate deadweight losses by ignoring its effect on forms of compensation and patterns of consumption the full deadweight loss is easily calculated using the compensated elasticity of taxable income to changes in tax rates because leisure excludable income and deductible consumption are a hicksian composite good microeconomic estimates imply a deadweight loss of as much as 30 of revenue or more than ten times harberger s classic 1964 estimate the relative deadweight loss caused by increasing existing tax rates is substantially greater and may exceed 2 per 1 of revenue

appropriating signs and meaning the elusive economics of trademark this paper deals with economic analysis of trademark its presence in markets is originally connected with the problem of information asymmetries and the need to provide information for assisting exchanges so as to avert the market failure brought about by adverse selection however this information conveying function is also accompanied by a differentiation effect arising from the power of persuasion that signs can exert on individuals the exploitation of differentiation has given rise to the practice of branding which ties markets and consumption to the realms of meaning and experience branding is so all pervasive in today s economy as to have somehow transfigured it so that the role of persuasion is now pre eminent nonetheless the mainstream economic theory tends to resist acknowledging this change which would to a large extent call into question well established hypotheses and theoretical tools the general response has therefore been to assume that the informational role of trademark predominates and to use this hypothesis to construct models welfare evaluations and policy prescriptions that bear little or no relation to the actual markets the opposing approach in the shadow of the nelson s and arrow s seminal papers on economics of information is recognising the idiosyncratic character of information and therefore drawing conclusions and devising solutions that while still based upon the welfare criterion also incorporate a wider awareness and a deeper representation of the scenario under study the present work attempts to move in this direction showing how different disciplines can provide some key epistemological tools for enabling economists to effectively evaluate the welfare outcomes of the introduction and progressive alteration of a particular intellectual property right within the realm of signs and meanings

inequality and media capture abstract popular support of redistributive policies depends on information they have about the tax system and efficiency of public projects mass media provides a convenient means for manipulating public opinion even when voters understand that the media can be biased i develop a theory of media capture in which the rich can influence information published in a media outlet at a cost the model shows that higher inequality is associated with lower media freedom this effect is stronger in democratic regimes i find empirical support for the model in both panel data and cross country analysis

how corruption influences foreign direct investment a panel data study abstract this article analyzes the sign and development of the effect of corruption on foreign direct investment fdi economic theory distinguishes grabbing hand corruption from helping hand corruption the former suggests a negative impact of corruption on fdi the latter one a positive effect empirically we apply a data set of 21 home and 59 developed and less developed host countries covering between 1983 and 1999 to investigate the corruption impact we employ a panel data model that particularly refers to the knowledge capital model of multinational activity we find a negative relationship between corruption and fdi this in turn suggests that the helping hand effects of corruption are outweighed by the grabbing hand effects further we observe that corruption is an important impediment of fdi in developed economies but not in less developed ones finally we demonstrate that the importance of corruption has decreased over the years

how work effort responds to wage taxation an experimental test of a zero top marginal tax rate abstract phelps 1973 sadka 1976 seade 1977 presented theorems that showed work effort could increase if the marginal tax rate was zero at the top income this was tested in a laboratory experiment the prediction was supported

the value of u s patents by owner and patent characteristics abstract this paper uses renewal data to estimate the value of u s patents controlling for patent and owner characteristics estimates of u s patent value are substantially larger than estimates for european patents however the ratio of u s patent value to r d for firms is only about 3 contrary to a common assertion patents issued to small patentees are much less valuable than those issued to large corporations litigated patents are more valuable as are highly cited patents however patent citations explain little variance in value suggesting limits to their use as a measure of patent quality

optimal tax and transfer programs for couples with extensive labor supply responses this paper analyzes the optimal design of general nonlinear tax transfer schedules for couples under unitary and collective approaches to family decision making we consider a double extensive model of labor supply where each spouse makes a labor force participation choice for given hours of work we present simple and intuitive optimal tax rules that generalize existing findings on the optimal taxation of single person households with extensive responses saez 2002 to the case of two person households with double extensive responses without income effects on labor supply optimal tax rules as a function of sufficient statistics are the same under the unitary and collective approaches with income effects on labor supply optimal tax rules under the two approaches continue to depend on the same sufficient statistics but the collective model features an additional pigouvian term arising from a within family participation externality finally we present microsimulations of tax reform for 15 european countries suggesting that a reduction of tax rates on secondary earners relative to primary earners is associated with strong welfare gains in all countries

optimal linear commodity taxation under optimal non linear income taxation abstract this paper analyzes optimal linear commodity taxes joint with non linear income taxes we provide optimal tax rules based on empirically observable elasticities earnings and commodity demands we demonstrate that commodities should be taxed subsidized if conditional on earnings doing so boosts labor supply as the critical role of commodity taxation is to alleviate distortions on labor supply caused by income taxation we extend the standard formula for optimal non linear income taxation for the presence of optimal linear commodity taxes we correct parts of the literature by showing that the optimal second best allocations derived by atkinson and stiglitz 1976 1980 cannot be supported by linear commodity taxes

time poor working super rich abstract this paper revisits the standard model of labor supply under two additional assumptions consumption requires time and some limited amount of work is enjoyable whereas introducing each assumption without the other one does not produce novel insights combining them together does if the wage rate is sufficiently high for top earners work has a positive marginal utility at the optimum and above a critical wage level it converts into a pure consumption good their labor supply curve is first backward bending and then vertical this can justify an optimal marginal tax rate on top incomes equal to 100 top earners in the vertical half line of the labor supply curve optimally refrain from spending their entire income at the macroeconomic level this can generate a lack of effective demand with some qualifications these findings carry over to models that include savings and philanthropy

tax evasion under differential taxation the economics of income source misreporting abstract if different income sources are subject to different rates of taxation a taxpayer may find it worthwhile to evade taxes by declaring part of his higher taxed income as stemming from a lower taxed source this paper inquires into the determinants of income source misreporting focusing on the relationships between misreporting and taxation under alternative penalty schemes allowing the taxpayer the choice between source misreporting and pure underreporting the paper examines also the relative amount of tax escaping the tax collector through the alternative forms of evasion and determines the conditions under which one will be preferred to the other

the paradox of openness appropriability external search and collaboration a b s t r a c t to innovate firms often need to draw from and collaborate with a large number of actors from outside their organization at the same time firms need also to be focused on capturing the returns from their innovative ideas this gives rise to a paradox of openness the creation of innovations often requires openness but the commercialization of innovations requires protection based on econometric analysis of data from a uk innovation survey we find a concave relationship between firms breadth of external search and formal collaboration for innovation and the strength of the firms appropriability strategies we show that this concave relationship is stronger for breadth of formal collaboration than for external search there is also partial evidence suggesting that the relationship is less pronounced for both external search and formal collaboration if firms do not draw ideas from or collaborate with competitors we explore the implications of these findings for the literature on open innovation and innovation strategy 2013 the authors published by elsevier b v all rights reserved

defying the law of gravity the political economy of international migration bilateral flows of international migrants exhibit tremendous variance both across destination countries and over time to explain this variance studies of international migration tend to focus on economic determinants such as income differentials or on social conditions such as the presence of coethnics in certain destination countries the authors argue that migration is driven not solely by economic or social determinants rather the political environment across destinations plays a substantively large role in influencing bilateral migration flows they test the importance of the political environment citizenship rights and the prominence of right wing parties using data on migration flows from 178 origin countries into 18 destination countries over the period 1980 2006 they find even after controlling for a variety of economic social policy and international variables that variation in political environments across time and destination plays a key role in observed patterns of international migration

income taxes property values and migration we consider the effects of income redistribution when people can migrate from one country to another and when land within each country is heterogeneous taxes related to income can then affect property values and can induce migration which further affects property values we show that under these conditions a utilitarian government should never equalize after tax incomes if migration is impossible it may even transfer income from the poor to the rich reducing the rents earned by absentee landlords the redistributive tax on the rich may be higher or lower when the rich can migrate than when they cannot a rawlsian government in the absence of mobility will equalize after tax incomes under mobility rawlsian governments cut their taxes if and only if the relative pre tax income of the poor is sufficiently low

self selection and pareto efficient taxation abstract this paper analyses the set of pareto efficient tax structures the formulation of the problem as one of self selection not only shows more clearly the similarity between this problem and a number of other problems such as the optimal pricing of a monopolist which have recently been the subject of extensive research but also allows the derivation of a number of new results we establish i under fairly weak conditions randomization of tax structures is desirable ii if different individuals are not perfect substitutes for one another in production then the general equilibrium effects until now largely ignored in the literature of changes in the tax structure may be dominant in determining the optimal tax structure in particular if the relative wage of high ability and low ability individuals depends on the relative supplies of labor the optimal tax structure entails a negative marginal tax rate on the high ability individuals and a positive marginal tax rate on the low ability individuals the marnitude of which depends on the elasticity of substitution iii if individuals differ in their preferences pareto efficient taxation may entail negative marginal tax rates for high incomes while iv if wage income is stochastic the marginal tax rate at the upper end may be 100 our analysis thus makes clear that the main qualitative properties of the optimal tax structure to which earlier studies called attention are not robust to these attempts to make the theory more realistic
