taxation and international migration of superstars evidence from the european football market we analyze the effects of top tax rates on international migration of football players in 14 european countries since 1985 both country case studies and multinomial regressions show evidence of strong mobility responses to tax rates with an elasticity of the number of foreign domestic players to the net of tax rate around one around 0 15 we also find evidence of sorting effects low taxes attract highability players who displace low ability players and displacement effects low taxes on foreigners displace domestic players those results can be rationalized in a simple model of migration and taxation with rigid labor demand jel f22 h24 h31 j44 j61 l83

voluntary disclosure of evaded taxes increasing revenue or increasing incentives to evade many countries apply lower fines to tax evading individuals when they voluntarily disclose the tax evasion they committed i model such voluntary disclosure mechanisms theoretically and show that while such mechanisms increase the incentive to evade taxes they nevertheless increase tax revenues net of administrative costs i confirm the importance of administrative costs in a survey of german competent local tax authorities i then test the effects of voluntary disclosure on the tax evasion decision using the introduction of the 2009 offshore voluntary disclosure program in the u s for identification the analysis confirms that the introduction of voluntary disclosure increases tax evasion

regional inequalities in europe have they really been decreasing inequalities within the european community are analysed both at the national and the regional level from 1984 to 1988 based on the per capita income levels some convergence has been occurring amoung ec national economies however some regions seem to have been carrying the burden of closing the gap among nations performances the role of migration is analysed in some countries migration has been a factor tending to disguise the tendencies going on thereby promoting a misleading idea of regional convergence

transfer fee regulations in european football abstract we analyze the impact of three different transfer fee systems on payoffs contract lengths training and effort incentives in european football the different regimes being used until 1995 pre bosman currently in use bosman and recently approved monti differ with respect to the transfer fee an initial club is entitled to depending on whether a player has a valid contract or not we show that the different systems differ only with respect to the contract length if the contract which maximizes the expected joint surplus of the initial club and the player is feasible under each system otherwise regime p is strictly dominated by regime b in terms of expected social welfare regime m leads to higher effort but lower incentives to invest in training compared to system b

income redistribution in open economies i propose a model of income redistribution in an open economy environment the world consists of a finite number of countries whose governments seek to maximize the welfare of their low skilled populations by taxing skilled workers labor income while tax competition limits the extent to which redistribution is possible as compared to the closed economy outcome when skilled people are internationally mobile i argue that race to the bottom does not necessarily occur even if the number of countries becomes arbitrarily large the asymptotic sustainability of the welfare state crucially depends on the statistical properties of the probability distribution of skilled people s location preferences

on the relationship between corruption and migration empirical evidence from a gravity model of migration this paper shows the relationship between corruption and migration in particular countries with much corruption are shown to encourage emigration and discourage immigration because they provide worse and unpredictable economic conditions more insecurity and a lower quality of life this hypothesis is confirmed empirically with a cross sectional dataset with bilateral migration data covering 230 countries well known implications of the gravity model are confirmed here larger populations a common language and a common border increase migration while distance between two countries decreases migration furthermore education gdp per capita inflation in the destination country as well as corruption and education in the origin country can robustly explain migration corruption thus appears to be a push factor of migration

consumers and the brain drain product and process design and the gains from emigration abstract we consider the welfare effects of skilled worker emigration in a context where skilled labor plays a role in product or process design we show such emigration can benefit the residents left behind even when consumers tastes exhibit a form of home bias this is because emigration improves the design of goods designed by skilled emigrants but consumed in the sending country in contrast to existing models of beneficial brain drain our results do not require agglomeration economies education related externalities remittances return migration or an emigration lottery instead they are driven purely by differences in market size that induce skilled emigrants to design better products or production processes abroad than at home

the incidence of income taxes on high earners in canada this article explores the brain drain explanation for the concentration of incomes in canada during the past 30 years namely that high skilled canadians make use of high salaries on offer in the united states to extract higher salaries at home if this is the case then for a given level of us salaries the threat to accept outside offers should be more credible when the canadian dollar is depreciating against the us dollar and weaker when the canadian dollar is appreciating the data are broadly consistent with this claim income concentration worsened during the depreciations of the 1980s and 1990s and eased when the canadian dollar began to appreciate in value the article develops a simple two parameter model based on the propositions that high earners in canada can use us salaries to bargain for higher salaries and that canadian high earners can shelter part of their income from personal income taxes it also offers some preliminary evidence about the parameter values consistent with available data the results suggest that higher top marginal personal income tax rates may potentially accentuate top end after tax income inequality if high earners are able to use their bargaining power to extract pay increases to offset higher tax rates then the burden of increased personal income taxes will be deflected elsewhere and may even have the perverse effect of making the after tax income distribution more unequal than it was before l incidence des impots sur le revenu des hauts salaries au canada cet article examine l hypothese des produits de base produits de base produits de base produits de base produits de base fuites des cerveaux comme explication pour la concentration des revenus au canada pendant les dernieres decennees c est a dire que les canadiens hautement qualifies se servent des salaires offerts aux etats unis pour negocier des salaires plus eleves au canada si tel est le cas la menace d emigrer aux etats unis est plus credible lorsque le dollar canadien deprecie contre le dollar americain et elle est moins credible pendant une appreciation les grandes lignes des variations des donnees vont dans le sens de cette conjecture la concentration des revenus a accru pendant les depreciations des annees 1980 et 1990 et cette tendance a renverse la direction suite a l appreciation du dollar canadien l article developpe un modele a deux parametres base sur les propositions que les hauts salaries au canada peuvent utiliser les salaires aux etats unis afin de negocier des salaires plus eleves et que les hauts salaries se servent de la planification fiscale afin de mettre une partie de leurs revenus a l abri des impots des estimations preliminaires pour les parametres sont presentees les resultats suggerent qu une augmentation du taux marginal d imposition pourrait meme accentuer l inegalite des revenus apres impots si les hauts salaries sont capables de negocier des salaires plus eleves face aux augmentations des taux d imposition le fardeau du nouvel impot serait refile ailleurs la distribution des revenus nets pourrait meme devenir encore plus inegale

the informational content of implied volatility implied volatility is widely believed to be informationally superior to historical volatility because it is the markets forecast of future volatility but for s p 100 index options the most actively traded contract in the united states we find implied volatility in aggregate and across subsamples separated by maturity and strike price implied volatility has virtually no correlation with future volatility and it does not incorporate the information contained in recent observed volatility article published by oxford university press on behalf of the society for financial studies in its journal the review of financial studies

can state taxes redistribute income abstract the evidence presented in this paper supports the basic theoretical presumption that state and local governments cannot redistribute income since individuals can avoid unfavorable taxes by migrating to jurisdictions that offer more favorable tax conditions a relatively unfavorable tax will cause gross wages to adjust until the resulting net wage is equal to that available elsewhere the current empirical findings go beyond confirming this long run tendency and show that gross wages adjust rapidly to the changing tax environment thus states cannot redistribute income for a period of even a few years the adjustment of gross wages to tax rates implies that a more progressive tax system raises the cost to firms of hiring more highly skilled employees and reduces the cost of lower skilled labor a more progressive tax thus induces firms to hire fewer high skilled employees and to hire more low skilled employees since state taxes cannot alter net wages there can be no trade off at the state level between distribution goals and economic efficiency shifts in state tax progressivity by altering the structure of employment in the state and distorting the mix of labor inputs used by firms in the state create deadweight efficiency losses without achieving any net redistribution

white discrimination in provision of black education plantations and towns abstract we present a model of public provision of education for blacks in two discriminatory regimes white plantation controlled and white yeoman town controlled we show that the ability to migrate to a non discriminating district constrains the ability of both types of regimes to discriminate the model produces time series of educational outcomes for whites and blacks that mimic the behavior seen in post reconstruction south carolina to the onset of the civil rights act it also fits the post world war ii black white income differentials

immigration and inequality immigration is often viewed as a proximate cause of the rising wage gap between highand low skilled workers nevertheless there is controversy over the appropriate theoretical and empirical framework for measuring the presumed effect and over the precise magnitudes involved this paper offers an overview and synthesis of existing knowledge on the relationship between immigration and inequality focusing on evidence from cross city comparisons in the u s while some researchers have claimed that a cross city research design is inherently flawed i argue that the evidence from cross city comparisons is remarkably consistent with recent findings based on aggregate time series data in particular cross city and aggregate time series comparisons provide support for three key conclusions 1 workers with below high school education are perfect substitutes for those with a high school education 2 high school equivalent and college equivalent workers are imperfect substitutes with an elasticity of substitution on the order of 2 3 within education groups immigrants and natives are imperfect substitutes together these results imply that the average impacts of recent immigrant inflows on the relative wages of u s natives are small the effects on overall wage inequality including natives and immigrants are larger reflecting the concentration of immigrants in the tails of the skill distribution and higher residual inequality among immigrants than natives even so immigration accounts for a small share 5 of the increase in u s wage inequality between 1980 and 2000

how should capital be taxed this survey discusses how capital should be taxed in advanced economies we review the theoretical optimal tax literature survey empirical studies on the distribution of capital and the distortion

income taxation and the diversity of consumer goods a political economy approach after tax income inequality has risen since the mid 1990s as increases in market income inequality have not been offset by greater fiscal redistribution we argue that the substantial increase in the diversity of consumer goods has mitigated mounting political pressures for redistribution within a probabilistic voting framework we demonstrate that if the share of diversified goods in the consumption bundle increases sufficiently with income then an increase in goods diversity can reduce the political equilibrium tax rate focusing on oecd countries we find empirical support for both the model s micro political foundations and the implied relation between goods diversity and fiscal policy outcomes

information about bank risk in options prices abstract the volatility of its share price reflects the volatility of the market value of a bank s assets we present data for the volatilities of individual banks shares that are implied by the prices of options on the banks shares we present evidence that implied volatilities iv s better forecast actual future volatilities of share prices than historical volatilities do banks iv s are correlated with marketwide volatility with the levels of their own share prices with their own subordinated debt yield spreads and with other banks iv s bank capital reduces the response of iv s to market volatility iv s are likely to add information about bank risk that is timely cheap objective and useful

taxation and the international mobility of inventors we study the eect of top tax rates on superstar inventors international mobility since 1977 using panel data on inventors from the u s and european patent oces we exploit the dierential impact of changes in top tax rates on inventors of dierent qualities superstar inventors location choices are signicantly aected by top tax rates in our preferred specication the elasticity to the net of tax rate of the number of domestic superstar inventors is around 0 03 while that of foreign superstar inventors is around 1 these elasticities are larger for inventors in multinational companies an inventor is less sensitive to taxes in a country if his company performs a higher share of its research there

brain drain and human capital formation in developing countries winners and losers using new data on emigration rates by education level we examine the impact of brain drain migration on human capital formation in developing countries we find evidence of a positive effect of skilled migration prospects on gross human capital formation in a cross section of 127 countries for each country of the sample we then estimate the net effect of the brain drain using counterfactual simulations countries combining relatively low levels of human capital and low emigration rates are shown to experience a beneficial brain drain and conversely there are more losers than winners and the former tend to lose relatively more than what the latter gain

taxing the rich affluent households can respond to taxation with means that are not economically viable for the rest of the population such as sophisticated tax plans and international tax arbitrage this article studies an economy in which an inequality averse social planner faces agents who have access to a tax avoidance technology with subadditive costs and who can shape the risk profile of their income as they see fit subadditive avoidance costs imply that optimal taxation cannot be progressive at the top this in turn may trigger excessive risk taking when the avoidance technology consists in costly migration between two countries that compete fiscally we show that an endogenous increase in inequality due to risk taking makes progressive taxation more fragile which vindicates in turn risk taking and can lead to equilibria with regressive tax rates at the top and high migrations of wealth towards the smaller country

comments on information about bank risk in options prices the question being raised by the authors does implied volatility provide information about the risk of the bank swidler and wilcox 2002 is important and of great interest not only to the regulators but also to investors and risk managers indeed implied volatilities can be calculated every day and if they provide unambiguous information about bank risk then it is a useful variable to monitor therefore as a risk manager i have read this paper with great interest eq 1 in the paper constitutes the backbone of the argument developed by the authors r 2 g 2 r 2 1 where re and ra denote the volatility of equity and asset returns respectively and g is the elasticity of equity price to asset value eq 1 follows directly from merton s 1974 model where equity is a call option on the assets of the bank with the same maturity as the zero coupon debt which constitutes the only debt financing of the bank and with the strike price equal to the face value of the zero coupon debt two comments come to mind when looking at eq 1 firstly intuitively if the volatility of the asset returns increases then the probability of default may indeed increase keeping everything else constant why do i say may increase if the volatility increases this will increase the asset s beta assuming positive correlation with the market portfolio and hence the expected return an increase in the expected rate of return will in turn lower the probability of default hence the net effect of an increase in the asset volatility on the risk of default is

relativity mobility and optimal nonlinear income taxation in an open economy abstract recent evidence suggests that globalization has reduced the barriers to international labor mobility and induced more cross country social comparisons in an open economy with tax driven migration and consumption externalities relativity we derive an optimal tax formula that subsumes existing ones obtained under a maximin social objective and additively separable utility and sign the second best mirrleesian marginal tax rates for all skill levels we establish the thresholds of the elasticity and level of migration to determine when relativity and inequality act as complements or substitutes in shaping the optimal top tax rate under both nash and stackelberg tax competition if the migration probability of top income workers is approximately 50 numerical calculation using parameter estimates from empirical studies shows that the country with labor inflow outflow implements over 10 lower higher marginal tax rates than suggested by the autarky equilibrium of kanbur and tuomala 2013

the selection of high skilled emigrants we measure selection among high skilled emigrants from germany using predicted earnings migrants to less equal countries are positively selected relative to nonmigrants while migrants to more equal countries are negatively selected consistent with the prediction in borjas 1987 positive selection to less equal countries reflects university quality and grades and negative selection to more equal countries reflects university subject and gender migrants to the united states are highly positively selected and concentrated in stem fields our results highlight the relevance of the borjas model for high skilled individuals when credit constraints and other migration barriers are unlikely to be binding

changes in the labor supply behavior of married women 1980 2000 using march current population survey data we investigate married women s labor supply from 1980 to 2000 we find a large rightward shift in their labor supply function for annual hours in the 1980s with little shift in the 1990s these shifts account for most of the slowdown in the growth of labor supply during this period a major development was the dramatic decrease in the responsiveness of married women s labor supply to their own and husbands wages their own wage elasticity fell by 50 56 while their cross wage elasticity fell by 38 47 in absolute value

brain waste educated immigrants in the u s labor market the authors investigate the occupational placement of immigrants in the u s labor market using census data they find striking differences among highly educated immigrants from different countries even after they control for individuals age experience and level of education with some exceptions educated immigrants from latin american and eastern european countries are more likely to end up in unskilled jobs than immigrants from asia and industrial countries a large part of the variation can be explained by attributes of the country of origin that influence the quality of human capital such as expenditure on tertiary education and the use of english as a medium of instruction performance is adversely affected by military conflict at home which may weaken institutions that create human capital and lower the threshold quality of immigrants the selection effects of u s immigration policy also play an important role in explaining cross country variation the observed under placement of educated migrants might be alleviated if home and host countries cooperate by sharing information on labor market conditions and work toward the recognition of qualifications

regional earnings convergence the case of northern ireland black b 1985 regional earnings convergence the case of northern ireland reg studies 19 1 7 this paper analyses the rapid increase in the earnings of northern ireland male manual workers relative to the united kingdom average which has taken place in recent decades it identifies four factors which help explain this convergence first there has been a big increase in hours worked in northern ireland relative to the uk average since 1961 second the influence of changing industrial structure is highlighted in addition the impact of a range of government policies and developments in the institutional process of pay determination on earnings is examined the paper concludes that the convergence reflects the erosion of regional distinctiveness as earnings levels are increasingly influenced by national factors

tax harmonization and tax competition in the european union lessons from switzerland abstract this paper presents empirical evidence on individual income tax competition in switzerland tax competition has some influence on the spread of people with high income over the cantons and it is partly capitalised in dwelling rents however it neither leads to a collapse of public good supply nor makes redistribution by the fiscal authorities impossible thus if tax competition works well in switzerland there is no reason why it should have disastrous effects in a future european union

tax competition and the distribution of income in this paper we provide a two country two class model of asymmetric capital tax competition we show formally that poor people living in small countries can benefit from capital tax competition and therefore they are in favor of it in order to benefit from capital inflow from larger countries poor people in smaller countries accept less within country income redistribution as a consequence between country income inequality is increased by tax competition

tax induced mobility evidence from a foreigners tax scheme in switzerland abstract we study location choice and residential mobility responses to local income taxes exploiting a special tax regime which applies to foreign employees residing in switzerland the institutional setting used generates a deterministic duration threshold at 5 years of stay in the country at which the local tax rates an individual faces simultaneously change in all municipalities we exploit this exogenous variation by applying a fuzzy regression discontinuity design to merged survey and administrative individual level data a dynamic location choice model allows us to derive testable hypotheses of individuals location choices and mobility decisions our estimated treatment effects provide causal evidence for tax induced residential choices and tax induced intra national mobility

immigrant links to the home country empirical implications for u s bilateral trade flows immigrants ties to their home countries can play a key role in fostering bilateral trade linkages immigrant ties include knowledge of home country markets language preferences and business contacts that have the potential to decrease trading transaction costs empirical results for the united states suggest that immigrant links have historically been important in increasing bilateral trade flows with immigrants home countries copyright 1994 by mit press

the relation between implied and realized volatility abstract previous research finds the volatility implied by s p 100 index option prices to be a biased and inefficient forecast of future volatility and to contain little or no incremental information beyond that in past realized volatility in contrast we find that implied volatility outperforms past volatility in forecasting future volatility and even subsumes the information content of past volatility in some of our specifications our results differ from previous studies because we use longer time series and nonoverlapping data a regime shift around the october 1987 crash explains why implied volatility is more biased in previous work

the economic returns to schooling in the west bank and gaza strip the author uses micro data from the labor force surveys conducted in the west bank and the gaza strip during 1981 91 to show that during 1981 87 wage differences between schooling groups fell by well over one half this sharp reduction is associated with large increases in the size of the educated palestinian labor force since the returns to schooling for israeli jews were stable the decline in returns to schooling for palestinians is consistent with the notion that the returns to schooling in the territories were determined largely by the forces of supply and demand in a segmented market for skilled labor copyright 1995 by american economic association

can a brain drain be good for growth in the source economy this paper analyzes the interaction between income distribution human capital accumulation and migration it shows that when migration is not a certainty a brain drain may increase average productivity and equality in the source economy even though average productivity is a positive function of past average levels of human capital in an economy it is also shown how the temporary possibility of emigration may permanently increase the average level of productivity of an economy

mobility and redistribution the ability of individuals to move freely from one jurisdiction to another is generally seen as a constraint on the amount of redistribution that each jurisdiction within a system of governments can undertake in this paper we look at this proposition by developing a positive analysis of income redistribution by local governments in a federal system we ask how much redistribution occurs when only local governments can have tax transfer instruments individuals can move freely among jurisdictions and voters in each jurisdiction are fully aware of the migration effects of redistributive policies local redistribution is shown to induce sorting of the population with the poorest households located in the communities that provide the most redistribution while the threat of out migration affects the potential for redistribution our results suggest that significant local redistribution is nonetheless feasible numerical computations indicate that the proportion of residents who are renters is a major factor affecting the local choice of level of redistribution

on the trade impact of nominal exchange rate volatility what is the effect of nominal exchange rate variability on trade i argue that the methods conventionally used to answer this perennial question are plagued by a variety of sources of systematic bias i propose a novel approach that simultaneously addresses all of these biases and present new estimates from a broad sample of countries from 1970 to 1997 the estimates indicate that nominal exchange rate variability has no significant impact on trade flows

spillover effects of stricter immigration policies abstract we provide evidence for the existence of spillover effects of national immigration policies by estimating the effect of stricter family reunification rules in denmark on migration behavior we reach three main conclusions using danish register data we first show that stricter rules for reunification led to a clear and significant increase in emigration of danish citizens with immigrant background most of the emigrants left denmark for sweden a neighboring country in which reunification was possible next using swedish register data we find that affected individuals emigrating to sweden actually came for family formation purposes finally we demonstrate that not all individuals that came to sweden to reunite with a partner stayed in the country of those leaving return migration to denmark was most common our results indicate that potential spillover effects from national migration policies should be taken into account when forming migration policy

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

a closed form garch option valuation model this paper develops a closed form option valuation formula for a spot asset whose variance follows a garch p q process that can be correlated with the returns of the spot asset it provides the first readily computed option formula for a random volatility model that can be estimated and implemented solely on the basis of observables the single lag version of this model contains heston s 1993 stochastic volatility model as a continuous time limit empirical analysis on s p500 index options shows that the out of sample valuation errors from the single lag version of the garch model are substantially lower than the ad hoc black scholes model of dumas fleming and whaley 1998 that uses a separate implied volatility for each option to fit to the smirk smile in implied volatilities the garch model remains superior even though the parameters of the garch model are held constant and volatility is filtered from the history of asset prices while the ad hoc black scholes model is updated every period the improvement is largely due to the ability of the garch model to simultaneously capture the correlation of volatility with spot returns and the path dependence in volatility article published by oxford university press on behalf of the society for financial studies in its journal the review of financial studies

return migration human capital accumulation and the brain drain in this paper we present a model that explains migrations as decisions that respond to where human capital can be acquired more efficiently and where the return to human capital is highest the basic framework is a dynamic roy model in which a worker possesses two distinct skills that can be augmented by learning by doing there are different implicit price in different countries and different rates of skill accumulation our analysis contributes to the literature on the selection of immigrants and return migrants by offering a richer framework that may help to accommodate selections of emigrants and return migrants that are not immediately compatible with the one dimensional skill model our analysis has also implications for the debate on brain drain and brain gain in the two skills model presented here return migration can lead to a mitigation of the brain drain or even the creation of a brain gain where those who return bring the home country augmented local skills

globalization brain drain and development this paper reviews four decades of economics research on the brain drain with a focus on recent contributions and on development issues we first assess the magnitude intensity and determinants of the brain drain showing that brain drain or high skill migration is becoming a dominant pattern of international migration and a major aspect of globalization we then use a stylized growth model to analyze the various channels through which a brain drain affects the sending countries and review the evidence on these channels the recent empirical literature shows that high skill emigration need not deplete a country s human capital stock and can generate positive network externalities three case studies are also considered the african medical brain drain the exodus of european scientists to the united states and the role of the indian diaspora in the development of india s information technology sector we conclude with a discussion of the implications of the analysis for education immigration and international taxation policies in a global context

differential taxation and occupational choice we develop a framework to study optimal sector specific taxation where each agent chooses an occupation by comparing her skill differential with the tax burden differential across sectors because skills are not perfectly transferable the diamond mirrlees theorem according to which the second best entails production efficiency fails social welfare can be increased by inducing some agents to join the sector in which their productivity is not the highest at the optimum income taxes balance the marginal losses from inter sector migration with the marginal gains from tailoring tax schedules to the distribution of productivities in each sector tagging a calibrated model indicates that sector specific taxation generates substantive welfare gains when skill transferability decreases with income as it enables the government to increase average taxes on high earners with large wage premia

climatic factors as determinants of international migration we examine environmental change as a potential determinant of international migration we distinguish between unexpected short run factors captured by natural disasters as well as long run climate change and climate variability captured by deviations and volatilities of temperatures and rainfall from and around their long run averages starting from a simple neo classical model we use a panel dataset of bilateral migration flows for the period 1960 2000 that allows us to control for numerous time varying and time invariant factors we find no direct impact of climatic change on international migration across our entire sample these results are robust when conditioning on characteristics of origin countries as well as when further considering migrants returning home and the potential endogeneity of our network variable in contrast there is evidence of indirect effects of environmental factors going through wages we further find strong evidence that natural disasters beget greater flows of migrants to urban environs

the economic consequences of corporate tax rates reductions in the eu evidence using a computable general equilibrium model in a globalised world governments are eager to attract foreign investors by lowering corporate tax rates recent trends point towards a revival of a race to the bottom in corporate income tax cit rates in developed economies eu countries have been active in this respect a generalised fall in cit rate could prove detrimental to tax revenues and trigger increase in other taxes to meet fiscal policy objectives however it could also spur investment and growth and prove to be a good fiscal policy strategy if as a result the corporate tax base increases the final economic and fiscal impact of a reduction in cit rates is therefore unclear using a cge model we find that uncoordinated tax reforms significantly impact national economies and third country effects can be significant when large countries implement cit rate cuts small countries are better off unilaterally reducing their cit rate at the expense of other eu countries we find that negative spillovers are mitigated when the country reducing its cit rate restores its budget balance by cutting either public expenditures or social transfers a larger degree of non eu capital mobility also tends to reduce the negative spillover effects of unilateral cit rate reductions

income maximization and the selection and sorting of international migrants abstract two prominent features of international labor movements are that the more educated are more likely to emigrate positive selection and more educated migrants are more likely to settle in destination countries with high rewards to skill positive sorting using data on emigrant stocks by schooling level and source country in oecd destinations we find that a simple model of income maximization can account for both phenomena results on selection show that migrants for a source destination pair are more educated relative to non migrants the larger is the absolute skill related difference in earnings between the destination country and the source results on sorting indicate that the relative stock of more educated migrants in a destination is increasing in the absolute earnings difference between high and low skilled workers we use our framework to compare alternative specifications of international migration estimate the magnitude of migration costs by source destination pair and assess the contribution of wage differences to how migrants sort themselves across destination countries

efficiency gains from liberalizing labor mobility in this paper we quantify the effect of a complete liberalization of cross border migration on the world gdp and its distribution across regions we build a general equilibrium model endogenizing bilateral migration and income disparities between and within countries our calibration strategy uses data on effective and potential migration to identify total migration costs and visa costs by education level data on potential migration reveal that the number of people in the world who have a desire to migrate is around 400 million this number is much smaller than that predicted in previous studies and reflects the existence of high incompressible migration costs in our benchmark framework liberalizing migration increases the world gdp by 11 5 12 5 percent in the medium term our robustness analysis reveals that the gains are always limited in the range of 7 0 percent with schooling externalities to 17 9 percent if network effects are accounted for

efficient equilibrium convergence heterogeneity and growth abstract an endogenous growth model arising from task specialization is used to examine the effects of differing initial human capital distributions two macroeconomic phenomena are produced income convergence and leapfrogging of living standards income convergence occurs for all countries in the same market arising from diminishing returns to individual human capital leapfrogging occurs by comparing countries in two separate markets income leapfrogging can occur because the stationary growth rate increases with market size and human capital heterogeneity reduces growth the introduction of coordination costs of task assignment can produce gains in welfare and growth from human capital heterogeneity

a voluntary brain drain tax abstract a major roadblock to the implementation of bhagwati s proposal to allow developing countries to tax skilled emigrants residing in developed countries the brain drain is the administrative problems associated with collecting this tax in the absence of developed country cooperation this paper provides a partial solution to these problems involving the tax treatment of emigrants who return to their countries of origin the tax system is structured so that returning emigrants who previously paid the brain drain tax face lower tax payments than those who evaded the brain drain tax given the expected value of this tax benefit emigrants are willing to pay the brain drain tax in the basic model a source country s optimal tax system includes this brain drain tax and does not distort migration decisions

international migration and educated unemployment this paper provides a novel explanation of educated unemployment which is a salient feature of the labor markets in a number of developing countries in a simple job search framework we show that educated unemployment is caused by the prospect of international migration that is by the possibility of a brain drain in addition the analysis shows that a developing country may end up with more educated workers despite the brain drain and educated unemployment

how can scandinavians tax so much american visitors to scandinavian countries are often puzzled by what they observe despite large income redistribution through distortionary taxes and transfers these are very high income countries they rank among the highest in the world in terms of income per capita as well as most other economic and social outcomes the economic and social success of scandinavia poses important questions for economics and for those arguing against large redistribution based on its supposedly detrimental effect on economic growth and welfare to form a basis for the discussion table 1 shows tax revenues and income tax rates in the three scandinavian countries denmark norway and sweden as compared to other european countries and the united states we see that the tax to gdp ratio and the tax rates on income are much higher in scandinavia than elsewhere the top marginal tax rates are about 60 70 percent in the scandinavian countries as opposed to only 43 percent in the united states the contrast is even more striking when considering the so called participation tax rate which is the effective average tax rate on labor force participation when accounting for the distortions due to income taxes payroll taxes consumption taxes and means tested transfers this tax rate is around 80 percent in the scandinavian countries implying that an average worker entering employment will be able to increase consumption by only 20 percent of earned income due to the combined effect of higher taxes and lower transfers by contrast the average worker in the united states gets to keep 63 percent of earnings when accounting for the full effect of the tax and

bunching and non bunching at kink points of the swedish tax schedule recent microeconometric studies of taxpayers responsiveness to taxation have shown that intensive margin labor supply and earnings elasticities typically are modest and sometimes equal to zero however a common view is that long run responses might still be large since micro estimates are downward biased owing to optimization frictions in this paper we estimate the taxable income elasticity at a very large kink point of the swedish tax schedule using the bunching method during the period of study the change in the log net of tax rate reached a maximum value of 45 6 interestingly we obtain a precise elasticity estimate of zero for wage earners at this large kink the size of the kink allows us to derive tighter bounds on the long run elasticity than previous studies if wage earners on average tolerate 1 of their disposable income in optimization costs the upper bound on the long run taxable income elasticity is 0 39 we also evaluate the performance of the bunching estimator by performing monte carlo simulations

millionaire migration and taxation of the elite evidence from administrative data a growing number of u s states have adopted millionaire taxes on top income earners this increases the progressivity of state tax systems but it raises concerns about tax flight elites migrating from high tax to low tax states draining state revenues and undermining redistributive social policies are top income earners transitory millionaires searching for lower tax places to live or are they embedded elites who are reluctant to migrate away from places where they have been highly successful this question is central to understanding the social consequences of progressive taxation we draw on administrative tax returns for all million dollar income earners in the united states over 13 years tracking the states from which millionaires file their taxes our dataset contains 45 million tax records and provides census scale panel data on top income earners we advance two core analyses 1 state to state migration of millionaires over the long term and 2 a sharply focused discontinuity anal

emigration and democracy migration is an important yet neglected determinant of institutions this paper documents the channels through which emigration affects home country institutions and considers dynamic panel regressions for a large sample of developing countries the authors find that emigration and human capital both increase democracy and economic freedom this implies that unskilled skilled emigration has a positive ambiguous impact on institutional quality simulations show an impact of skilled emigration that is generally positive significant for a few countries and for many countries once incentive effects of emigration on human capital formation are accounted for

migration and optimal income taxes abstract the issue addressed in this paper is the optimal taxation of incomes earned in the home economy and of incomes earned abroad when people can migrate as a preliminary the optimal taxation of home incomes when there is migration and no taxation of foreign incomes is discussed then in a more general setting we deal with optimal taxation of different kinds of labour when another kind of labour is not taxable and show how this bears on the taxation of foreign incomes the last sections of the paper analyse a simple model in which people choose between taxable labour at home taxable labour abroad and untaxable labour a condition is found implying that the optimal tax on foreign income is higher than on the home income of a person of equal utility

equality under threat by the talented evidence from worker managed firms does workplace democracy engender greater pay equality are high ability individuals more likely to quit egalitarian organisational regimes the article revisits this long standing issue by analysing the interplay between compensation structure and quit behaviour in the distinct yet underexplored institutional setting of worker managed firms the analysis is based on novel administrative data sources which allow constructing a simple ordinal measure of the workers ability type the article s key findings are that worker managed firms have a more compressed compensation structure than conventional firms and high ability members are more likely than other members to exit

the brain drain and the world distribution of income abstract skilled emigration or brain drain from developing to developed countries is becoming the dominant pattern of international migration today such migration is likely to affect the world distribution of income both directly through the mobility of people and indirectly as the prospect of migration affects the rate of return to education in both the sending and receiving economies this migration pattern will therefore affect human capital accumulation and fertility decisions in both the sending and receiving economies this paper analyzes these effects in a dynamic two country model of the world economy where agents in both countries make optimal fertility and human capital decisions the implications of the analysis for the world distribution of income are derived in the light of recent empirical findings of the brain drain literature the analysis shows that the current trend towards predominantly skilled emigration from poor to rich countries may in the long run increase inequality in the world distribution of income as relatively poor countries grow large in terms of population in the short run however it is possible for world inequality to fall due to rises in gdp per capita in large developing economies with sufficiently low skilled emigration rates

relocation of the rich migration in response to top tax rate changes from spanish reforms a spanish reform granted regions the authority to set income tax rates resulting in substantial tax differentials using administrative data we find that conditional on moving taxes have a signi

remittances and temporary migration in this paper we study the remittance behavior of immigrants and how it relates to temporary versus permanent migration plans we use a unique data source that provides unusual detail on remittances and return plans and follows the same household over time our data allows us also to distinguish between different purposes of remittances we analyze the association between individual and household characteristics and the geographic location of the family as well as return plans and remittances the panel nature of our data allows us to condition on household fixed effects to address measurement error and reverse causality we use an instrumental variable estimator our results show that changes in return plans are related to large changes in remittance flows

does talent migration increase inequality a quantitative assessment in football labour market abstract i analyze the links between talent migration and cross country inequality by exploiting the 1995 elimination of mobility restrictions on the european football labor market i develop a simple model and employ an empirical dataset to estimate its parameters through simulation analysis i compare actual data with a counterfactual no mobility restriction trajectory and conclude that the elimination of mobility barriers increases not only cross country inequality by 25 but also global output in the football economy by stimulating the production of new talent in africa latin and central america

constitutional change and inequality in scotland what scope does a sub national economy have to affect the level of inequality does a policy menu consistent with the theories of fiscal federalism provide for an ability to affect inequality measures or does this ability require the powers of a nation state in this paper we discuss these questions in the context of the debate around the scottish independence referendum in which inequality has played a prominent role and ask whether independence further devolution or simply different policies under the current constitutional framework are capable of helping scotland make the transition to a less unequal income distribution we provide a series of estimates of the impact of different policy choices upon inequality in scotland and discuss inequality reduction in the context of different constitutional options

mobile labor multiple tax instruments and tax competition abstract the tax competition literature shows that local governments keep property tax rates inefficiently low to prevent capital outflows thereby underproviding local public goods this paper adds mobile labor and an alternative tax instrument to the model jurisdictions have access to a property tax levied on land and capital plus either a head tax or a labor tax scale economies in public good provision create incentives to use the property tax but these incentives are not accompanied by increased incentives to underprovide public goods in contrast underprovision is associated with the use of a distortionary labor tax

migration and wage effects of taxing top earners evidence from the foreigners tax scheme in denmark this paper analyzes the eects of income taxation on the international migration and earnings of top earners using a danish preferential foreigner tax scheme and populationwide danish administrative data this scheme introduced in 1991 allows new immigrants with high earnings to be taxed at a preferential at rate for a duration of three years we obtain two main results first the scheme has doubled the number of highly paid foreigners in denmark relative to slightly less paid and therefore ineligible foreigners this translates into a very large elasticity of migration with respect to 1 minus the average tax rate on foreigners between 1 5 and 2 second we nd compelling evidence of a negative eect of the scheme induced reduction in the average tax rate on pre tax earnings of foreign migrants at the individual level this nding can be rationalized by a matching frictions

commuting and taxes theory empirics and welfare implications we examine the effect of interstate differences in income taxes on commuting times our theoretical model introduces a border into a model of an urban area and shows that differences in average tax rates distort commuting patterns but the sign of the effect depends on whether taxes are residence based or employment based empirically tax differentials have a large effect on commuting times for affluent households and mobile households we show that commuting times are a sufficient statistic to measure the spatial welfare effects of tax policy the model and empirical design can be used by economists to study other policy differences this article is protected by copyright all rights reserved

immigration and welfare magnets this article investigates if the location choices made by immigrants when they arrive in the united states are influenced by the interstate dispersion in welfare benefits income maximizing behavior implies that foreign born welfare recipients unlike their native born counterparts may be clustered in the states that offer the highest benefits the empirical analysis indicates that immigrant welfare recipients are indeed more heavily clustered in high benefit states than the immigrants who do not receive welfare or than natives as a result the welfare participation rate of immigrants is much more sensitive to changes in welfare benefits than that of natives

balanced budget rules and fiscal outcomes evidence from historical constitutions this paper studies the long run fiscal consequences of balanced budget rules bbr that are enshrined in a country s constitution using historical data dating back to the 19th century and applying a difference in difference approach we find that the introduction of a constitutional bbr reduces government debt to gdp and expenditure to gdp ratios on average by around 11 and 3 percentage points respectively we do not find evidence that bbrs affect tax revenues our analysis indicates that such rules reduce the probability of experiencing a debt crisis and that the effective enforcement of bbrs can be conditional on the quality of democratic institutions in addition we implement an instrumental variable approach by instrumenting the probability of having budget rules on de jure constraints on changing the constitution this and other tests suggest that the relations we find are largely causal going from bbrs to fiscal outcomes
