lessons from the tequila crisis abstract this paper draws several important lessons from the tequila crisis of 1994 and 1995 the overriding lesson is that the dynamics of financial crises in emerging market countries differ from those in industrialized countries because institutional features of their debt markets differ several policy lessons for emerging market countries also emerge from the analysis 1 pegged exchange rate regimes are extremely dangerous 2 strong prudential supervision of the banking system is critical for prevention of financial crises 3 financial liberalization must be managed extremely carefully and 4 different policies are needed to promote recovery in emerging market countries than those that are applicable to industrialized countries

fixing exchange rates a virtual quest for fundamentals abstract fixed exchange rates are less volatile than floating rates but the volatility of macroeconomic variables such as money and output does not change very much across exchange rate regimes this suggests that exchange rate models based only on macroeconomic fundamentals are unlikely to be very successful it also suggests that there is no clear tradeoff between reduced exchange rate volatility and macroeconomic stability

spatial search migration and regional unemployment the dominant explanation of spatial unemployment in the literature assumes that workers must live in an area in order to be able to access job offers this gives rise to compensating variations in local wages and unemployment however for many occupations search is clearly conducted over longer distances from a home base in the model presented in this paper migration and unemployment are analysed both when the optimal search field is local as in the traditional model and when search is conducted over longer distances i compare equilibria in these two regimes and discuss the implications for regional policy

the classification and performance of alternative exchange rate systems abstract owing to dissatisfaction with the imf s de jure classification of exchange rate regimes a substantial literature has emerged presenting de facto classifications of exchange rate systems and using the latter classifications to compare performances of alternative regimes in terms of key macroeconomic variables this paper critically reviews the literature on de facto regimes in particular the paper 1 describes the main methodologies that have been used to construct de facto codings 2 surveys the empirical literature generated by de facto regime codings and 3 lays out the problems inherent in constructing de facto classifications the empirical literature is found to yield few robust findings we argue that the as yet unfulfilled objective of this literature and the major research agenda for the future in this area lies in the need of a more thorough investigation of the degree of monetary policy independence without relying exclusively on movements in exchange rates an agenda the attainment of which is made especially challenging because of the lack of comprehensive and reliable data on reserves and interest rates

the economics of exchange rate regimes a review essay the exchange rate regime issue has taken centre stage in discussions of international economic policy much of the profession appears to have been converted to the hypothesis of the vanishing middle regime for countries well integrated into world capital markets there is little if any middle ground between floating exchange rates and monetary unification this paper considers the exchange rate regime issue in the context of recent books on the subject by w max corden and morris goldstein both authors prescribe managed floating exchange rates supplemented with inflation targeting for emerging market economies under managed floating and with a credible monetary policy the public finances in order and strengthened debt management and prudential regulation the exchange rate is free to act as a market gauge for assessing policies and as a mode of conflict resolution both authors also argue however that no exchange rate regime is a holy grail ultimately a credible exchange rate regime depends upon the trust evoked by governments there is no exchange rate regime whether of the managed floating or hard fix variety that can eradicate a history of failed stabilisation attempts

real exchange rates and relative prices an empirical investigation abstract this paper uncovers a striking empirical regularity the consumer price of a good relative to a different good within a country tends to be much less variable than the price of that good relative to a similar good in another country this fact seems to hold for all goods except very simple homogeneous products models of real exchange rates are likely to have predictions regarding this relation so this fact may provide a useful gauge for discriminating among models

taxation and housing old questions new answers this paper sketches how the tax reforms of the 1980s affected the incentives and distortions associated with tax policy toward housing markets there are three principal conclusions 1 reductions in marginal tax rates particularly for high income households reduced the tax induced distortion in the user cost of owner occupied housing this lowered the deadweight losses associated with the favorable tax treatment of homeownership 2 the increase in the standard deduction in the tax reform act of 1986 tra86 removed several million middle income homeowners who previously itemized from the ranks of itemizers for these households tra86 raised the marginal cost of owner occupied housing these changes also exacerbated the regressive nature of the mortgage interest subsidy in 1988 more than half of the tax losses associated with mortgage interest deductions accrued to the 8 of taxpayers with the highest economic incomes 3 tra86 reduced incentives for rental housing investment contributing to the decline in new multifamily housing starts from 500 000 per year in 1985 to less than 150 000 in 1991 in the long run these policies will lead to higher rents this abstract was borrowed from another version of this item

reap what you sow agricultural technology urbanization and structural change abstract this paper studies how productivity enhancing agricultural technology affects urbanization by provoking structural change we investigate these issues using a natural experiment in the united states the results show that technologies which improve crop productivity lead to a less urbanized economy as economic activity relocates from manufacturing and services towards agriculture the effects are highly persistent and are driven by the technology increasing agricultural labor demand our findings highlight the potentially unintended disruptive force of innovative technologies

amenity values versus land constraints the spatial effects of natural landscape features on housing values when local amenities are tied to natural land use features that cannot be developed for physical or regulatory reasons the corresponding implicit price estimates from a hedonic housing model may reflect local supply constraints and confound estimation of natural amenity values using a spatial simultaneous equations model of housing values and migration we examine whether local supply constraints from natural or preserved features have influenced the housing market results indicate that constraints associated with the presence of water bodies and some types of open space preservation have contributed to higher housing prices offsetting local demand for these natural amenities jel c31 r23

the impact of supply constraints on house prices in england we test the theoretical prediction that house prices respond more strongly to changes in local earnings in places with tight supply constraints using a unique panel dataset of 353 local planning authorities in england between 1974 and 2008 exploiting exogenous variation from a policy reform vote shares and historical density to identify the endogenous constraints measures we find that regulatory constraints have a substantive positive impact on the house price earnings elasticity the effect of constraints due to scarcity of developable land is largely confined to highly urbanised areas and uneven topography has a quantitatively less meaningful impact

credibility of policies versus credibility of policymakers standard models of policy credibility defined as the expectation that an announced policy will be carried out emphasize the preferences of the policymaker and the role of tough policies in signaling toughness and raising credibility whether a policy is carried out however will also reflect the state of the economy we present a model in which a policymaker maintains a fixed parity in good times but devalues if the unemployment rate gets too high our main conclusion is that if there is persistence in unemployment observing a tough policy in a given period may lower rather than raise the credibility of a no devaluation pledge in subsequent periods we test this implication on ems interest rates and find support for our hypothesis

the unequal geographic burden of federal taxation in the united states workers in cities offering above average wages cities with high productivity low quality of life or inefficient housing sectors pay 27 percent more in federal taxes than otherwise identical workers in cities offering below average wages according to simulation results taxes lower long run employment levels in high wage areas by 13 percent and land and housing prices by 21 and 5 percent causing locational inefficiencies costing 0 23 percent of income or 28 billion in 2008 employment is shifted from north to south and from urban to rural areas tax deductions index taxes partially to local cost of living improving locational efficiency

studying optimal paternalism illustrated by a model of sin taxes the classical economic approach to policy analysis assumes that people always respond optimally to the costs and benefits of their available choices a great deal of evidence suggests however that in some contexts people make errors that lead them not to behave in their own best interests economic policy prescriptions might change once we recognize that humans are humanly rational rather than superhumanly rational and in particular it may be fruitful for economists to study the possible advantages of paternalistic policies that help people make better choices we propose an approach for studying optimal paternalism that follows naturally from standard assumptions and methods of economic theory write down assumptions about the distribution of rational and irrational types of agents about the available policy instruments and about the government s information about agents and then investigate which policies achieve the most efficient outcomes in other words economists ought to treat the analysis of optimal paternalism as a mechanism design problem when some agents might be boundedly rational this approach has many advantages first and foremost by explicitly addressing when and how people do and don t pursue their own best interests economists will be better able to contribute to policy debates to contribute to debates over regulating private financial decisions we must study whether financial decisions are based on fallacious statistical reasoning and whether self control problems lead people to borrow too heavily to contribute to debates over teenage smoking we must study whether teenagers become smokers against their long run best interest economists will and should be ignored if we continue to insist that it is axiomatic that constantly trading stocks or accumulating consumer debt or becoming a heroin addict must be optimal for the people doing these things merely because they have chosen to do it a second advantage of our approach is that it forces us to look for the best feasible policy our

estimating the general equilibrium benefits of large changes in spatially delineated public goods the purpose of this article is to report a new approach for measuring the general equilibrium willingness to pay for large changes in spatially delineated public goods such as air quality we estimate the parameters of a locational equilibrium model and compute equilibria for alternative scenarios characterizing the availability of public goods within a system of communities welfare measures take into consideration the adjustments of households in equilibrium to nonmarginal changes in public goods the framework is used to analyze willingness to pay for reductions in ozone concentrations in southern california between 1990 and 1995

public conservation land and employment growth in the northern forest region we quantify the effect that public conservation lands have on employment growth in the northern forest region of the united states a model of simultaneous employment and net migration growth is estimated with data on non metropolitan counties from 1990 to 1997 exogenous variables include the 1990 share of the land base in public conservation uses we find that net migration rates were higher in counties with more conservation lands but the effects are relatively small no significant effect on employment growth is detected as well variables measuring changes in public timber harvests have no effect on employment growth

people places and earnings differentials in scotland abstractpeople places and earnings differentials in scotland regional studies this paper investigates the contribution of people and place effects to earnings differentials in scotland using individual and regional data the main sources of differentials are attributed to workers characteristics people effects particularly academic and vocational qualifications followed by occupational and industrial affiliations on the other hand differences in the attributes of local area labour markets place effects explain only a small part of individual earnings differentials the most relevant spatial attribute is local area human capital the findings suggest that people based policies are likely to be more effective at improving workers earnings prospects than place based policies

an optimum currency area odyssey abstract the theory of optimum currency areas was conceived and developed in three highly influential papers written by mundell 1961 mckinnon 1963 and kenen 1969 those authors identified characteristics that potential members of a monetary union should ideally possess in order to make it feasible to surrender a nationally tailored monetary policy and the adjustment of an exchange rate of a national currency we trace the development of optimum currency area theory which after a flurry of research into the subject in the 1960s was relegated to intellectual purgatory for about 20 years we then discuss factors that led to a renewed interest into the subject beginning in the early 1990s milton friedman plays a pivotal role in our narrative friedman s work on monetary integration in the early 1950s presaged subsequent optimum currency area contributions mundell s classic formulation of an optimal currency area was aimed in part at refuting friedman s strong case for floating exchange rates and friedman s work on the role of monetary policy had the effect of helping to revive interest in optimum currency area analysis the paper concludes with a discussion of recent analytical work using new keynesian models which has the promise of fulfilling the unfinished agenda set out by the original contributors to the optimum currency area literature that is providing a consistent framework in which a country s characteristics can be used to determine its optimal exchange rate regime

real exchange rates under alternative nominal exchange rate systems abstract the paper develops an equilibrium model of the determination of exchange rates the relative price of nontraded goods and the current account the focus is on the effects of various real and nominal disturbances and the conditions under which the nominal exchange rate system is neutral with respect to real variables in the economy the model demonstrates an assymetry in the roles of trade and nontraded goods in affecting exchange rates an econometric investigation of the raltion between the exchange rate system and the variability of real exchange rates provides some evidence against the neutrality hypothesis

choosing an exchange rate system abstract the focus of academic discussions of exchange rate policy has shifted in recent years the new literature on exchange rate regime choice emphasizes considerations relating to the problems of credibility in exchange rate targeting and the connections between exchange rate regime choices and choices of monetary and fiscal policy arguments for exchange rate targeting are reviewed under most circumstances and for most countries a system of freely floating exchange rates is likely to be a better choice than attempting to peg the exchange rate

non adherence to a low fat diet an economic perspective abstract despite bearing increased risk of suffering a heart attack failure to adhere to a low fat dietary regimen is wide spread the paper applies an expected utility maximization model to inquire into the individual s decision to deviate from a prescribed low fat diet offering an economic explanation for excess high fat consumption the implications of self protection against the risk of dying from an attack are further examined the analysis reveals that self protection and dietary adherence can be complements suggesting that public health policy may help reduce both the risk of an attack and the risk of dying from an attack through providing incentives for self protection

a theory of urban growth in an economy experiencing endogenous economic growth and exogenous population growth we explore two main themes how urbanization affects efficiency of the growth process and how growth affects patterns of urbanization localized information spillovers promote agglomeration and human capital accumulation fosters endogenous growth individual city sizes grow with local human capital accumulation and knowledge spillovers and city numbers generally increase which we demonstrate is consistent with empirical evidence we analyze whether local governments can successfully internalize local dynamic externalities in addition we explore how growth involves real income differences across city types and how urbanization can foster income inequality most nonagricultural production in developed countries occurs in metropolitan areas the underlying reasons why economic activity agglomerates into cities localized information and knowledge spillover also make cities the engines of economic growth in an we gratefully acknowledge support of the national science foundation grants sbr 9422440 and sbr9730142 for this research the work has benefited from conversations with harl ryder on the dynamics of the model and from comments by gilles duranton and participants in seminars at brown colorado and texas austin and a presentation at an isit seminar sponsored by the centre for economic policy research and the national bureau of economic research

did the junk food tax make the hungarians eat healthier i analyse whether the introduction of the unhealthy food tax lead to significant improvements in the dietary habits of the hungarian population i focus on the consumption of processed and unprocessed food before and after the tax was levied on a range of food high in salt and sugar using data from a large scale household panel data set i estimate the consumed quantities of processed food to decrease by 3 4 due to the unhealthy food tax while the consumed quantities of unprocessed food increased by 1 1 the lowest income groups were the most responsive to the introduction of the tax despite data limitations the results indicate moderate improvement in population diet that is likely to be attributable to the tax

the macroeconomics of the great depression a comparative approach recently research on the causes of the great depression has shifted from a heavy emphasis on events in the united states to a broader more comparative approach that examines the interwar experiences of many countries simultaneously in this lecture i survey the current state of our knowledge about the depression from a comparative perspective on the aggregate demand side of the economy comparative analysis has greatly strengthened the empirical case for monetary shocks as a major driving force of the depression an interesting possibility suggested by this analysis is that the worldwide monetary collapse that began in 1931 may be interpreted as a jump from one nash equilibrium to another on the aggregate supply side comparative empirical studies provide support for both induced financial crisis and sticky nominal wages as mechanisms by which nominal shocks had real effects still unresolved is why nominal wages did not adjust more quickly in the face of mass unemployment this abstract was borrowed from another version of this item

bidding for firms recently toyota sought a plant location in the united states the 800 million plant will employ 3000 workers and numerous states offered toyota generous investment incentives hoping this would induce toyota to select their state the commonwealth of kentucky won this competition but the price was high the present value of the payments exceeds 125 million the payment of investment incentives for the toyota plant is not unique in 1976 pennsylvania paid 75 million to attract a volkswagen plan nissan honda and mazda received generous investment incentives when locating plants in the united states and this bidding is not limited to states to attract the headquarters of the presbyterian church usa with its 1300 jobs and 38 million annual payroll civic leaders in louisville kentucky offered the church a warehouse and 6 2 million for renovation of the structure bidding the church away from kansas city missouri in this paper we contend that this competition may result from the average cost pricing of publicly provided goods and services 2 when the marginal cost of providing a firm and its workers with public services is less than the tax revenue they generate a government may offer the firm subsidies that reduce the distortions the average cost pricing of the public service creates thus this competition for industry is not a zero sum game where the subsidies are only transfers from the government to the firm rather these subsidies may facilitate the efficient location of industry

the economic causes of obesity a survey abstract obesity rates have increased dramatically over the last 30 years rising obesity has developed into a considerable worldwide public health problem with significant economic and social consequences accordingly obesity has become a subject of economic research this paper provides a broad survey of the recent and growing economic literature on the causes of obesity the literature both theoretical and empirical overall aims to explain the rising obesity trend and to identify the factors that contribute to obesity also surveyed are non economic causes and consequences of obesity and the interconnection with economic influences an understanding of the causes of obesity allows policies to be considered that might stem the global increase in obesity

new estimates of climate demand evidence from location choice abstract we develop and apply to census data a new method for estimating climate demand the method is useful for ranking quality of life based upon a willingness to pay criterion our two major findings are that the willingness to pay quality of life index is correlated with the hedonic approach s ranking but that the migration approach generates much larger estimates of willingness to pay for a more moderate climate this finding is relevant for evaluating the economic impact of global warming

on the microeconomics of food and malnutrition under endogenous discounting abstract this paper explores the microeconomics and dynamics of food and nutrition it examines the linkages between malnutrition and the incentive to invest and accumulate capital the analysis focuses on a dynamic model where preferences about the future depend on nutrition and health situations of malnutrition cover both ends of the spectrum from nutrient deficiency to obesity the model involves preferences that are not time additive and exhibit endogenous discounting this provides a framework to investigate the factors affecting consumption and investment behavior the adverse investment incentives of malnutrition are examined

junk food home cooking physical activity and obesity the effect of the fat tax and the thin subsidy abstract in an effort to reduce the growing prevalence of obesity a tax on junk foods known as fat tax has been proposed the revenue from which could be used to finance a thin subsidy for healthy foods or exercising equipment the present paper addresses the fat tax and thin subsidy within a food intake rational choice model assuming that healthy meals are cooked at home with purchased ingredients and time input the paper examines the effects on obesity of a tax on junk food meals and a subsidy to cooking ingredients distinguishing between a weight conscious and a non weight conscious individual and between a weight conscious individual who is physically active and physically inactive the results show that for a non weight conscious individual a fat tax will unambiguously reduce obesity whereas a thin subsidy may increase obesity however for a weight conscious individual particularly one who is physically active even a fat tax may increase obesity as it may reduce not just the consumption of junk food but also the time devoted to physical activity the paper explores conditions under which obesity will rise fall or remain intact following the introduction of a fat tax or a thin subsidy

wages rents and the quality of life this study focuses on the role of wages and rents in allocating workers to locations with various quantities of amenities the theory demonstrates that if the amenity is also productive then the sign of the wage gradient is unclear while the rent gradient is positive the theory is extended to include the housing market and nontraded goods these extensions require little modification of the conclusion the empirical work on wages shows that the regional wage differences can be explained largely by these local attributes with the use of site price data implicit prices are estimated and quality of life rankings for the cities are computed

implicit bands in the yen dollar exchange rate this article attempts to identify implicit exchange rate regimes for the yen dollar exchange rate to that end we apply a sequential procedure that considers both the dynamics of exchange rates and central bank interventions to data covering the period from 1971 to 2003 our results suggest that implicit bands existed in two subperiods april december 1980 and march october 1987 the latter coinciding with the louvre accord furthermore the study of the credibility of such implicit bands indicates the high degree of confidence attributed by economic agents to the evolution of the yen dollar exchange rate within the detected implicit band rate thus lending further support to the relevance of such implicit bands

income and wealth heterogeneity in the macroeconomy how do movements in the distribution of income and wealth affect the macroeconomy we analyze this question using a calibrated version of the stochastic growth model with partially uninsurable idiosyncratic risk and movements in aggregate productivity our main finding is that in the stationary stochastic equilibrium the behavior of the macroeconomic aggregates can be almost perfectly described using only the mean of the wealth distribution this result is robust to substantial changes in both parameter values and model specification our benchmark model whose only difference from the representative agent framework is the existence of uninsurable idiosyncratic risk displays far less cross sectional dispersion and skewness in wealth than u s data however an extension that relies on a small amount of heterogeneity in thrift does succeed in replicating the key features of the wealth data furthermore this extension features aggregate time series that depart significantly from permanent income behavior

explaining the duration of exchange rate pegs abstract this paper is an empirical investigation of the duration of exchange rate pegs in 16 latin american countries and jamaica we identify factors that influence peg duration using logit analysis the real exchange rate and the level of international liquidity are significant determinants of the monthly likelihood of devaluation structural variables such as the openness of an economy and its geographical trade concentration and political variables such as changes in the executive also significantly affect the likelihood of a devaluation there is some evidence that the likelihood of a devaluation first rises and subsequently declines during the first year of a peg

understanding the city size wage gap in 2000 wages of full time full year workers were more than 30 percent higher in metropolitan areas of over 1 5 million people than rural areas the monotonic relationship between wages and city size is robust to controls for age schooling and labor market experience in this paper we decompose the city size wage gap into various components we propose an on the job search model that incorporates latent ability search frictions firm worker match quality human capital accumulation and endogenous migration between large medium and small cities counterfactual simulations of the model indicate that variation in returns to experience and differences in wage intercepts across location type are the most important mechanisms contributing to the overall city size wage premium steeper returns to experience in larger cities is more important for college graduates while differences in wage intercepts is more important for high school graduates sorting on unobserved ability within education group and differences in labor market search frictions and distributions of firm worker match quality contribute little or slightly negatively to observed city size wage premia in both samples

we are what we eat obesity income and social comparisons abstract the empirical evidence of a non monotone relation between income and obesity is not well explained we build a theoretical model combining income inequality and social comparisons to explain the link between income and obesity and study tax policy implications for fighting obesity we assume that differences in food consumption patterns between poor and wealthy households partly reflect positionality which is the concern for social status our key assumption is that positionality for low calorie food consumption is positively related to a country s wealth in this framework body weight outcomes reflect competing income and positionality effects yielding the following results we explain the link between average obesity rates and standards of living and suggest the existence of a kuznets curve for obesity in accordance with empirical evidence for cross sections of the population we explain the observed correlation between income and obesity which is positive in poor countries and negative in rich countries we find that increasing the relative cost of high calorie food is less effective at decreasing the relative weight of poor individuals in rich countries than in poor countries

earmarking and the political support of fat taxes a fat and a healthy good provide immediate gratification and cause health costs or benefits in the long run which are misperceived additionally the fat good healthy good increases decreases health care costs by increasing decreasing the probability of suffering from a chronic disease in the future individuals differ in income and in their degree of misperceptions concerning the health effects of the consumption of fat and of healthy goods the level of the fat tax is determined through majority voting individuals vote according to their misperceived utility function consequently excessive fat consumption is not due to a self control problem but due to information deficiencies or cognitive inability to process information a fraction of the fat tax proceeds is earmarked to reduce health insurance premiums while the remaining fraction finances a subsidy on the healthy good this earmarking rule is determined at a constitutional stage to maximize utilitarian or rawlsian welfare anticipating the induced political equilibrium we show that the fat tax in the political equilibrium is always lower than the utilitarian fat tax this is no longer necessarily true with a rawlsian objective the determination of the optimal earmarking rule is quite complex even in the utilitarian case it is not just used to boost political support for the fat tax instead it may involve a tradeoff between the fat tax and the healthy good subsidy

the benefits and costs of monetary union in southern africa a critical survey of the literature with the 14 members of the southern african development community sadc having set the objective of adopting a common currency for the year 2018 an expanding empirical literature has emerged evaluating the benefits and costs of a common currency area in southern africa this paper reviews that literature focusing on two categories of studies 1 those that assume that a country s characteristics are invariant to the adoption of a common currency and 2 those that assume that a monetary union alters an economy s structure resulting in trade creation and credibility gains the literature reviewed suggests that a relatively small group of countries typically including south africa satisfies the criteria necessary for monetary unification the literature also suggests that in a monetary union comprising all sadc countries and a regional central bank that sets monetary policy to reflect the average economic conditions e g fiscal balances in the region the potential losses i e higher inflation from giving up an existing credible national central bank a relevant consideration for south africa could outweigh any potential benefits of trade creation resulting from a common currency

estimating a dynamic spatial equilibrium model to evaluate the welfare implications of regional adjustment processes the decline of the rust belt this article develops and estimates a new dynamic spatial equilibrium model to study the regional transition dynamics and its impact on individual and aggregate welfare the model consists of a multiregion multisector economy comprised of overlapping generations of individuals with heterogeneous skills and mobility costs the empirical findings suggest that a large fraction of the decline of the rust belt can be attributed to the reduction in its region specific comparative advantage in the goods producing sector this decline generated significant differences in welfare across regions policy experiments show that such inequality can be significantly reduced through place based policies

business cycles and the exchange rate system some international evidence this paper investigates the differences in time series behavior of key economic aggregates under alternative exchange rate systems we use a postwar sample of 49 countries to compare the behavior of output consumption trade flows government consumption spending and real exchange rates under alternative exchange rate systems pegged floating and cooperative systems such as the ems we then examine evidence from two particular episodes involving canada and ireland of changes in the exchange rate system aside from greater variability of real exchange rates under flexible than under pegged nominal exchange rate systems we find little evidence of systematic differences in the behavior of macroeconomic aggregates or international trade flows under alternative exchange rate systems these results are of interest because a large class of theoretical models implies that the nominal exchange rate system has important effects on a number of macroeconomic quantities

understanding gross worker flows across u s states abstract the main cross sectional and time series properties of state level gross and net worker flows wages and rents are characterized using micro data from the u s census a dynamic general equilibrium model of worker migration is introduced to explain the stylized facts in the model a location may experience simultaneous inflows and outflows of workers recent migrants choose to migrate more often than incumbent workers thus locations that attract high numbers of migrants also tend to experience high outflow rates this pattern is a robust feature of the data and cannot be explained by models of net flows only

an estimable dynamic general equilibrium model of work schooling and occupational choice this paper develops and estimates a dynamic general equilibrium overlapping generations model of career decisions the model is fit to data on life cycle employment schooling and occupation decisions and on life cycle labor earnings within and between cohorts observed in the us between 1968 and 1993 based on the estimates of the model the impact of cohort size on skill prices and consequently on career decisions is assessed compared to a baseline case in which cohort size increased at a steady average rate and the fertility process was stationary it is found that the male baby bust generations born in the 1930s and 1940s faced higher skill prices by as much as 2 0 completed college at a higher rate by as much as 0 3 percentage points and worked more over the lifetime by as much as 0 1 years in contrast the males from the baby boom generations born in the 1950s and 1960s faced lower skill prices by as much as 1 5 completed college at a lower rate by as much as 1 0 percentage points and worked less over the lifetime by as much as 0 1 years the impact of cohort size is found to differ across gender due to the differential impact of fertility on the value of home production unlike males the female baby bust generations completed college at a lower rate by as much as 1 5 percentage points and worked less over the lifetime by as much as 0 5 years while the female baby boom generations completed college at a lower rate by as much as 1 5 percentage points and worked more over the lifetime by as much as 0 2 years a tuition subsidy experiment is also performed both in a general equilibrium setting in which skill prices are endogenous and in a partial equilibrium setting with fixed skill prices based on the estimated model a 1 increase in tuition is predicted to reduce college enrollment rates by 1 27 in partial equilibrium consistent with previous estimates and by 1 05 in the general equilibrium case thus for this policy experiment the partial equilibrium analysis of schooling choice would not differ significantly from the general equilibrium analysis

urban accounting and welfare why do people live in particular cities we can list many reasons but two are undoubtedly relevant agents can enjoy the city or be more productive there a combination of life amenities and productivity levels determines the size of cities but the positive effects of these characteristics are capped by the costs and frictions arising from congestion depending on city governance and the flexibility of markets these costs and frictions can be more or less important these city characteristics are in turn enhanced and amplified by the presence of urban externalities understanding the different forces that determine city sizes is crucial for answering a broad set of questions what is the relative importance of these forces in determining the size distribution of cities how much would we gain or lose if cities had similar amenities technology levels or frictions how much reallocation would this cause more generally what are the welfare implications of the location of agents across cities in this paper we provide a simple way of decomposing the characteristics that lead to the size distribution of cities into three main components efficiency amenities and excessive frictions we use a simple urban theory to calculate these components and to carry out a wide set of counterfactual exercises that provide answers to the questions we asked above the theory consists of a multi city model with monocentric cities that produce a single good workers decide how much to work and where to live efficiency is modeled as tfp amenities as directly affecting preferences

assessing the incidence and efficiency of a prominent place based policy abstract this paper empirically assesses the incidence and efficiency of round i of the federal urban empowerment zone ez program using confidential microdata from the decennial census and the longitudinal business database using rejected and future applicants to the ez program as controls we find that ez designation substantially increased employment in zone neighborhoods and generated wage increases for local workers without corresponding increases in population or the local cost of living the results suggest the efficiency costs of first round ezs were relatively modest jel h26 h77 j31 r23 r58

intersectoral labor mobility and the growth of the service sector one of the most striking changes in the u s economy over the past 50 years has been the growth in the service sector between 1950 and 2000 service sector employment grew from 57 to 75 percent of total employment however over this time the real hourly wage in the service sector grew only slightly faster than in the goods sector in this paper we assess whether or not the essential constancy of the relative wage implies that individuals face small costs of switching sectors and we quantify the relative importance of labor supply and demand factors in the growth of the service sector we specify and estimate a two sector labor market equilibrium model that allows us to address these empirical issues in a unified framework our estimates imply that there are large mobility costs output in both sectors would have been double their current levels if these mobility costs had been zero in addition we find that demand side factors that is technological change and movements in product and capital prices were responsible for the growth of the service sector

the causal link between financial incentives and weight loss an evidence based survey of the literature obesity and overweight are linked to diseases that cost society a significant amount of resources while behavior modification can reduce the problem instigating such lifestyle changes is an uneasy task one potential way to reduce the problem is through the use of financial incentives in this survey we review the available evidence properly emphasizing studies that credibly yield meaningful estimates of the effect of financial incentives on weight loss we find that the scientific literature on the subject has not yet satisfactorily settled whether such a mechanism is effective at eliciting the desired behavioral and health outcomes we therefore advocate a rigorous large scale randomized experiment to provide reliable estimates of the effect

government programs can improve local labor markets evidence from state enterprise zones federal empowerment zones and federal enterprise communities 1 abstract federal and state governments spend well over a billion dollars a year on programs that encourage employment development in disadvantaged labor markets through the use of subsidies and tax credits in this paper we use an estimation approach that is valid under relatively weak assumptions to measure the impact of state enterprise zones entzs federal empowerment zones empzs and federal enterprise community entc programs on local labor markets we find that all three programs have positive statistically significant impacts on local labor markets in terms of the unemployment rate the poverty rate the fraction with wage and salary income and employment further the effects of empz and entc designation are considerably larger than the impact of entz designation we find that our estimates are robust to allowing for a regression to the mean effect we also find that there are positive but statistically insignificant spillover effects to neighboring census tracts of each of these programs thus our positive estimates of these program impacts do not simply represent a transfer from the nearest non treated census tract to the treated census tract our results are noteworthy for several reasons first our study is the first to jointly look at these three programs thus allowing policy makers to compare the impacts of these programs second our paper along with a concurrent study by neumark and kolko 2008 is the first to carry out the estimation accounting for overlap between the programs third our estimation strategy is valid under weaker assumptions than those made in many previous studies we consider three comparison groups and let the data determine the appropriate group fourth in spite of our conservative estimation strategy by looking at national effects with disaggregated data we show that entz designation generally has a positive effect on the local labor market while most previous research on entzs much of which used more geographically aggregated data to look at state specific effects did not find any significant impacts fifth we note that there is little or no previous work on entcs overall our results strongly support the efficacy of these labor market interventions

going home evacuation migration decisions of hurricane katrina survivors in the wake of hurricane katrina many evacuees from the gulf region began the difficult process of deciding whether to rebuild or restart elsewhere we examine pre katrina gulf residents decision to return to the postdisaster gulf region which we call the return migration decision we estimate two separate return migration models first using data from a mail survey of individuals in the affected region and then focusing on self administered questionnaires of evacuees in houston our results indicate that return migration can be affected by household income age education level and employment marital and home ownership status but the results depend on the population under consideration we find no effect of connection to place on the return migration decision although the effect of income is relatively small within subsamples we find a much higher proportion of middle income households planning to return than lower income households when comparing across the subsamples in addition the real wage differential between home and host region influences the likelihood of return larger implicit costs in terms of foregone wages for returning induce a lower likelihood of return exploiting this difference at the individual level we are able to produce estimates of willingness to pay wtp to return home average wtp to return home for a sample of relatively poor households is estimated at 1 94 per hour or 3954 per year
