a random walk through mayfair art as a luxury good and evidence from dynamic models abstract the movement of international art prices in conjunction with other asset prices is preliminary to our understanding whether art is a luxury good it is well known that there are linkages between art market prices and equity prices however less is known about the structure of dependence between these variables and the influence of gold prices and sentiment we analyse art prices at the outset using granger causality and error correction models ecm to capture the long term dynamics between art prices equity markets gold prices and investor sentiment the dataset we use is unique and covers british art prices from 1895 to the present initial results do not give a complete picture of price movements or a fitting description of wealth effects to rectify this we look at short term dynamics in the art market we assume a regime switching model to describe the movement of prices using a threshold variable that drives prices into possibly locally explosive regimes these results indicate a dynamic wealth effect in that high low stock prices lead to subsequent increases decreases in art prices however this approach means that elasticities are now stochastic and we redefine what a luxury good is this is further explored by directly calculating elasticities from our model and its variants to analyse properties of art as a luxury good our threshold approach gives deeper insight into the impact of different market conditions than conventional ecm and cointegration modelling

legislated protection and the world trade organization tariff bindings and administered protection are two characteristics of the world trade organization wto that are little understood tariff bindings place a ceiling on tariffs that is not always reached whereas administered protection provides all industries with some minimum import protection effectively creating a floor for protection how do these policies affect applied most favored nation mfn tariff rates that are enacted through the legislature i model tariffs determined by a dynamic legislative process and show that low applied mfn tariffs are less likely with tariff bindings and more likely with administered protection than under purely legislated protection

asset prices and institutional investors empirical evidence indicates that trades by institutional investors have sizable effects on asset prices generating phenomena such as index effects asset class effects and others it is difficult to explain such phenomena within standard representative agent asset pricing models in this paper we consider an economy populated by institutional investors alongside standard retail investors institutions care about their performance relative to a certain index our framework is tractable admitting exact closed form expressions and produces the following analytical results we find that institutions optimally tilt their portfolios towards stocks that comprise their benchmark index the resulting price pressure boosts index stocks while leaving nonindex stocks unaffected by demanding a higher fraction of risky stocks than retail investors institutions amplify the index stock volatilities and aggregate stock market volatility and give rise to countercyclical sharpe ratios trades by institutions induce excess correlations among stocks that belong to their benchmark index generating an asset class effect institutions finance their additional purchases of index stocks by taking on leverage a policy prescription that calls for a reduction in leverage while reducing the riskiness of institutional portfolios would also reduce the ability of institutions to tilt their portfolios towards index stocks depressing the index level

the impact of social mobility and within family learning on voter preferences evidence from a sample of twins abstract income maximizing consumers should vote in predictable ways support for liberal redistributive governments should fall as income rises but weak empirical evidence for these voting patterns might suggest that voters are influenced by alternative factors such as perceptions of social mobility from within family learning to examine these effects this paper uses a data set of twins and a recently developed econometric approach to show that within family learning and family specific effects are important determinants of voting preferences and preferences for redistribution

growth adoption and use of mobile e commerce abstract we document some early effects of how mobile devices might change internet and retail commerce we present three main findings based on an analysis of ebay s mobile shopping application and core internet platform first early adopters of mobile e commerce applications appear to be people who already were relatively heavy internet commerce users second adoption of the mobile shopping application is associated with both an immediate and sustained increase in total platform purchasing with little evidence of substitution from the core platform third differences in user behavior across the mobile applications and the regular internet site are not yet so dramatic

a time series analysis of representative agent models of consumption andleisure choice under uncertainty this paper investigates empirically a model of aggregate consumption and leisure decisions in which utility from goods and leisure is nontime separable the nonseparability of preferences accommodates intertemporal substitution or complementarity of leisure and thereby affects the comovements in aggregate compensation and hours worked these cross relations are examined empirically using postwar monthly u s data on quantities real wages and the real return on the one month treasury bill the estimated values of the parameters governing preferences differ significantly from the values assumed in several studies of real business models several possible explanations of these discrepancies are discussed

the spirit of capitalism and savings behavior abstract this paper presents a capitalist spirit model of savings by including wealth in the intertemporal utility function while this model includes the life cycle model and bequest model as two special cases it sheds light on why wealth holding has tended to increase with age why decumulation of wealth after retirement has not happened and why households with and without children have not shown significant differences in their savings behavior the capitalist spirit approach is especially useful for understanding savings by the rich and savings across countries and over time jel e21 b10

macroeconomic implications of conspicuous consumption a sombartian dynamic model this chapter presents a dynamic general equilibrium model in which consumers have status preference i investigate the manner in which capital accumulation is impeded by conspicuous consumption a la corneo and jeanne j public econ 66 55 71 1997a following the literature social norms are given as either bandwagon type or snob type i then show that when the economy is characterized by a bandwagon type social norm capital accumulation exhibits interesting patterns those patterns include for example an oscillating convergence path the rise of the economy feeds its decay through conspicuous consumption and that decay suppresses conspicuous consumption and engenders prosperity as predicted by sombart liebe luxus und kapitalismus reprinted 1967 deutscher taschenbuch verlag munchen 1912

towards a micro founded theory of aggregate labour supply we build a heterogeneous agents life cycle model that captures a large number of salient features of individual male labour supply over the life cycle by education both along the intensive and extensive margins the model provides an aggregation theory of individual labour supply firmly grounded on individual level micro evidence and is used to study the aggregate labour supply responses to changes in the economic environment we find that the aggregate labour supply elasticity to a transitory wage shock is 1 75 with the extensive margin accounting for 62 of the response furthermore we find that the aggregate labour supply elasticity to a permanent compensated wage change is 0 44

global value chain perspective of us china trade and employment employment impact of trade is an issue of long debate recent literature seems to focus on partial equilibrium analysis of the jobs destruction in the us due to import competition from low cost countries particularly from china however as noted in world investment report 2011 wir 2012 indirect employment generated by trade can be substantial in addition to jobs directly generated by trade to which end a general equilibrium model is more relevant just as in a relay game it makes little sense to award or punish only the last runner in this paper a global value chain approach is adopted to examine the effects of the us china trade on employment by using a recently constructed world input output data it is made possible to account for jobs created along the value chain process it is found that china s exports to the us and to the world had created more job opportunities for its trade partners than any other countries in the world further china s exports to the us and to the world tended to generate more employment opportunities for the us services sector while us exports created more manufacturing jobs for the chinese workers finally in both countries exports the typical value chain products such as electrical and optical equipment were the most effective creators of jobs for both countries in line with recent work of global value chains our work sheds light on the employment effects of interconnected trade and provides an alternative interpretation for the impact of the us china trade on employment

asset pricing with heterogeneous beliefs and relative performance we propose an equilibrium asset pricing model in which agents with heterogeneous beliefs care about relative performance we find that the concern with relative performance leads agents to trade more similarly a development that has two effects first similar trading directly decreases volatility second similar trading decreases the impact of dominant agents the second effect dominates the first when agents expect large differences between their final performances and vice versa when agents expect small differences between their final performances compared with the case in which agents are unconcerned about relative performance the stock return volatility is higher when the second effect dominates and lower when the first effect dominates this paper also demonstrates that the concern about relative performance influences investors holdings stock prices and risk premia

asset prices and exchange rates in this paper we study the implications of introducing demand shocks and trade in goods into an otherwise standard international asset pricing model trade in goods gives rise to an additional channel of international propagation through the terms of trade absent in traditional single good asset pricing models the inclusion of demand shocks helps overturn many unrealistic implications of existing international flnance models in which productivity shocks are the sole source of uncertainty our model generates a rich set of implications on how stock bond and foreign exchange markets co move we solve the model in closed form which yields a system of equations that can be readily estimated empirically our estimation validates the main predictions of the theory

the world trade network and the environment this papers analyses the role of the world trade network on the environment we rely on methods developed for social network analysis to identify the most important countries in connecting trade between all the other countries in the world trade network we then estimate how the network or indirect effects from trade affect the environmental quality of a country as the trade networks are endogenously determined by trade and environmental conditions we use as instrumental variables the growth in the population of trade partners and the growth in the population of trade partners partners to exploit exogenous variation in the world trade network once we simultaneously estimate the environmental trade income and network equations using a three stage least square procedure we find that network effects harm the environmental quality of developed countries but improve the environment of developing countries

using the medicare buy in program to estimate the effect of medicaid on ssi participation aaron s yelowitz this article assesses the importance of receiving supplemental health insurance on participation in supplemental security income ssi for the elderly the implementation of the qualified medicare beneficiary qmb program offered a substitute for medicaid and expanded health insurance eligibility to a higher income level using a sample of elderly respondents aged 66 to 75 i find that the qmb program reduced ssi participation more than half of the qmb participants were previously covered by ssi and medicaid the calculations suggest that the qmb program was not as expensive as it might first appear because of reductions in ssi expenditure jel h53 138 j14 i introduction the supplemental security income ssi program in the united states provides assistance to elderly blind and disabled individuals who are poor it is federally financed and administered by the social security administration although much more attention has been focused on the former aid to families with dependent children afdc program which primarily targets poor single parent families more money was spent on cash relief for ssi recipients in 1993 23 6 billion compared to 22 3 billion 1 in addition to cash ssi recipients receive supplemental health insurance coverage for medicare similar to private medigap policies through the medicaid program this provides a second important benefit to ssi recipients in fiscal year 1993 medicaid expenditure for elderly categorically needy ssi recipients amounted to 14 1 billion 2 several studies have examined the importance of health insurance for working age adults in the labor market 3 in addition the effects of recent medicaid expansions for younger populations have been extensively studied 4 little is known however about the quantitative importance of medicaid on the ssi participation of the elderly the key obstacle in assessing this effect is that until recently medicaid eligibility had been closely related to ssi eligibility in most states this study analyzes the introduction of the qualified medicare beneficiary qmb program enacted in different states from 1987 to 1992 which offered supplemental health insurance coverage to the elderly without the need to participate in ssi the qmb program offered some of the same medicare cost sharing benefits that an elderly ssi recipient would receive from medicaid including the payment of medicare premiums deductibles and copayments 5 moreover the qmb program expanded medicaid coverage to individuals with higher inc omes and assets than the ssi program 6 the primary goal of this article is to document the link between the qmb program and the decision to participate in ssi i find that raising the income limit in qmb program significantly reduces ssi participation particularly among african americans and the less educated the coefficient estimates suggest that in the absence of the qmb buy in program ssi participation would have been 45 higher in 1992 than it actually was the caseload growth in the elderly ssi population would have looked very similar to the caseload growth of the disabled 851 population a group not eligible for qmb in addition the qmb program was considerably less expensive than one would infer from simply calculating the increased health care expenditure because of reductions in ssi expenditure for cash benefits the rest of the article is arranged as follows section ii outlines some relevant features of the ssi medicaid and qmb programs in particular it reviews how the income eligibility limits for qmb and ssi are computed the difference between those limits is a measure of how closely are medicaid and ssi linked it will subsequently be used as the key independent variable in the regression analysis this section also shows the cross sectional and time series variation in the qmb program section iii models the potential effects on ssi participation of the introduction of the qmb program and considers the role of information

in a world without borders the impact of taxes on internet commerce the rapid rise in sales over the internet and the fact that most internet buyers pay no sales tax has ignited a considerable debate over taxes and the internet this paper uses new data on the purchase decisions of approximately 25 000 online users to examine the effect of local sales taxes on internet commerce the results suggest that controlling for observable characteristics people living in high sales taxes locations are significantly more likely to buy online the results are quite robust and cannot be explained by unobserved technological sophistication shopping costs or other alternative explanations the magnitudes in the paper suggest that applying existing sales taxes to internet commerce might reduce the number of online buyers by up to 24 percent

difference in interim performance and risk taking with short sale constraints abstract absent much theory empirical works often rely on the following informal reasoning when looking for evidence of a mutual fund tournament if there is a tournament interim winners have incentives to decrease their portfolio volatility as they attempt to protect their lead while interim losers are expected to increase their volatility so as to catch up with winners we consider a rational model of a mutual fund tournament in the presence of short sale constraints and find the opposite interim winners choose more volatile portfolios in equilibrium than interim losers several empirical works present evidence consistent with our model however based on the above informal argument they appear to conclude against the tournament behavior we argue that this conclusion is unwarranted we also demonstrate that tournament incentives lead to differences in interim performance for otherwise identical managers and that mid year trading volume is inversely related to mid year stock return

optimal consumption and portfolio policies when asset prices follow a diffusion process abstract we consider a consumption portfolio problem in continuous time under uncertainty a martingale technique is employed to characterize optimal consumption portfolio policies when there exist nonnegativity constraints on consumption and on final wealth we also provide a way to compute and verify optimal policies our verification theorem for optimal policies involves a linear partial differential equation unlike the nonlinear partial differential equation of dynamic programming the relationship between our approach and dynamic programming is discussed we demonstrate our technique by explicitly computing optimal policies in a series of examples in particular we solve the optimal consumption portfolio problem for hyperbolic absolute risk aversion utility functions when the asset prices follow a geometric brownian motion the optimal policies in this case are no longer linear when nonnegativity constraints on consumption and on final wealth are included by these examples one can see that our approach is much easier than the dynamic programming approach

the spirit of capitalism and optimal capital taxation abstract the paper reexamines the famous chamley judd zero capital tax theorem in model economies where the agents are endowed with the spirit of capitalism it is shown that the limiting capital income tax is not zero in general and depends on the utility specifications rather than the production technology the similar formulas of optimal capital taxes are derived in more general settings with multiple physical capitals or heterogeneous agents capitalists and workers

a model of capital and crises we develop a model in which the capital of the intermediary sector plays a critical role in determining asset prices the model is cast within a dynamic general equilibrium economy and the role for intermediation is derived endogenously based on optimal contracting considerations low intermediary capital reduces the risk bearing capacity of the marginal investor we show how this force helps to explain patterns during financial crises the model replicates the observed rise during crises in sharpe ratios conditional volatility correlation in price movements of assets held by the intermediary sector and fall in riskless interest rates

restrictions on risk prices in dynamic term structure models restrictions on the risk pricing in dynamic term structure models dtsms tighten the link between cross sectional and time series variation of interest rates and make absence of arbitrage useful for inference about expectations this article presents a new econometric framework for estimation of affine gaussian dtsms under restrictions on risk prices which addresses the issues of a large model space and of model uncertainty using a bayesian approach a simulation study demonstrates the good performance of the proposed method data for u s treasury yields calls for tight restrictions on risk pricing only level risk is priced and only changes in the slope affect term premia incorporating the restrictions changes the model implied short rate expectations and term premia interest rate persistence is higher than in a maximally flexible model hence expectations of future short rates are more variable restrictions on risk prices help resolve the puzzle of implausibly stable short rate expectations in th

equilibrium prices in the presence of delegated portfolio management abstract this paper analyzes the asset pricing implications of commonly used portfolio management contracts linking the compensation of fund managers to the excess return of the managed portfolio over a benchmark portfolio the contract parameters the extent of delegation and equilibrium prices are all determined endogenously within the model we consider symmetric fulcrum performance fees distort the allocation of managed portfolios in a way that induces a significant and unambiguous positive effect on the prices of the assets included in the benchmark and a negative effect on the sharpe ratios asymmetric performance fees have more complex effects on equilibrium prices and sharpe ratios with the signs of these effects fluctuating stochastically over time in response to variations in the funds excess performance

intermediary asset pricing abstract we model the dynamics of risk premia during crises in asset markets where the marginal investor is a financial intermediary intermediaries face an equity capital constraint risk premia r

tax compliance and fiscal externalities evidence from u s diesel taxation abstract fiscal externalities across jurisdictions can arise from tax evasion and avoidance while the tax competition literature has generally focused on base shifting and the resulting positive fiscal externalities we show theoretically and empirically that negative fiscal externalities can dominate when the tax base is apportioned across jurisdictions this can lead to a negative relationship between jurisdiction size and the desired tax rate interstate truckers in the united states owe state diesel taxes based on diesel consumption which is apportioned based on the miles driven in each state we find that own state diesel sales fall when the diesel tax rates of other states rise suggesting that tax base evasion is the predominant source of externalities we then estimate a tax reaction specification finding that the own state tax rate is negatively correlated with the tax rates set in other states and with state size both consistent with the sign of the estimated fiscal externality

an endogenously switching ordered response model of information eligiblity and participation in ssi a model incorporating ssi participation information and perceptions of program eligibility is developed and estimated using data from the 1980 psid the model assumes the participation decision process begins in an uninformed regime and switches to an informed regime if the perceived benefits are sufficiently high in this informed regime individuals participate if perceived benefits exceed perceived costs we find that the acquisition of information is responsive to actual program generosity just as is participation itself faulty information which may be the proximate cause of low participation rates is apparently in part a consequence of low perceived net benefits copyright 1990 by mit press

dynamic asset allocation with relative wealth concerns in incomplete markets abstract in dynamic portfolio choice problems stochastic state variables such as stochastic volatility lead to adjustments of the optimal stock demand referred to as hedge terms or merton breeden terms by deriving an explicit solution in a two agent framework with a stochastic opportunity set we show that relative wealth concerns give rise to new hedge terms beyond the ordinary ones this is because the agents hedge against both exogenous changes in the state variable and endogenous decisions of the other agent depending on the parametrization of the model these new terms can significantly change the investors hedging demands we also show that both heterogeneity in risk aversion or relative wealth concerns can have similar effects on the heterogeneity in portfolio decisions formally we study a non cooperative non zero sum stochastic differential game for which we prove a verification theorem in a setting with an unspanned state variable

keeping one step ahead of the joneses status the distribution of wealth and long run growth assuming that the utility of each agent depends on its relative wealth position in the society this chapter constructs an endogenous growth model it is shown that even if the subjective discount rates differ across agents there exists a unique balanced growth equilibrium in which each agent owns a positive share of the world wealth it is also shown that if the agents are identical then an increase in savings incentives always raises the long run growth rate but if they are heterogeneous then an increase in savings incentives may lower the long run growth rate

sales taxes and internet commerce we estimate the sensitivity of internet retail purchasing to sales taxes using ebay data our first approach exploits the fact that a seller s location and therefore the applicable tax rate is revealed only after a buyer has expressed interest in an item we document how adverse tax surprises reduce the likelihood of purchase and shift subsequent purchases toward out of state sellers we then use more aggregated data to estimate that every one percentage point increase in a state s sales tax increases online purchases by state residents by almost 2 percent while decreasing their online purchases from state retailers by 3 4 percent jel h71 l81 l86

will destination based taxes be fully exploited when available an application to the u s commodity tax system abstract we develop a tax competition model that allows for the setting of both an origin based and a destination based commodity tax rate in the presence of avoidance and evasion in the presence of evasion jurisdictions will give cross border shoppers tax preferential treatment thus not fully exploiting the potential of destination based taxation moreover the divergence between origin based and destination based taxes is stronger when the incentives for consumers tax arbitrage opportunities increase the united states is one example of many such systems while sales taxes are due at the point of sale use taxes are due on goods purchased out of state we document that when able to set both rates a majority of jurisdictions levy destination based use taxes at a lower rate than origin based sales taxes in response to changes in state level policies that increase tax avoidance opportunities the results of the empirical model broadly confirm our theory

the delegated lucas tree we analyze the effects of the observed increased share of delegated capital for trading strategies and equilibrium prices by introducing delegation into a standard lucas exchange economy in equilibrium some investors trade on their own account but others decide to delegate trading to professional fund managers flow performance incentive functions describe how much capital clients provide to funds at each date as a function of past performance convex flow performance relations imply that the average fund outperforms the market in recessions and underperforms in expansions when the share of capital that is delegated is low all funds follow the same strategy however when the equilibrium share of delegated capital is high funds with identical incentives employ heterogeneous trading strategies a group of managers borrows to take on a levered position on the stock thus fund returns are dispersed in the cross section and the outstanding amounts of borrowing and lending increase the relation between the share of delegated capital and the sharpe ratio typically follows an inverse u shaped pattern jel g11 g12 g23 d02 d81 over the past thirty years there has been a gradual but profound change in the way money is invested in financial markets while almost 50 of u s equities were held directly in 1980 by 2007 this proportion decreased to approximately 20 see french 2008 what are the equilibrium implications of this shift in particular how does the increased presence of delegation affect trading strategies and prices to analyze the link between the incentives of financial institutions and asset prices we introduce financial intermediaries into a lucas exchange economy rather than study an optimal contracting problem we rely on empirical regularities inflows and assume a convex relation betweenflows and performance relative to the market as documented for example in chevalier and ellison 1997

the spirit of capitalism and stock market prices in existing theory wealth is no more valuable than its implied consumption rewards in reality investors acquire wealth not just for its implied consumption but for the resulting social status max m weber 1958 refers to this desire for wealth as the spirit of capitalism the authors examine both analytically and empirically implications of weber s hypothesis for consumption savings and stock prices when investors care about relative social status propensity to consume and risk taking behavior will depend on social standards and stock prices will be volatile the spirit of capitalism seems to be a driving force behind stock market volatility and economic growth copyright 1996 by american economic association

there goes gravity ebay and the death of distance we compare the effect of geographic distance on ebay and total international trade flows we consider the same 61 countries and basket of goods for both types of transactions we find the effect of distance to be on average 65 smaller on ebay we argue this difference is due to a reduction in search costs it increases with product differentiation and is higher when trade partners speak different languages when corruption in the exporting country is high and when uncertainty avoidance is high in the importing country moreover ebay s seller rating technology further reduces the distance effect on ebay

gender pay gaps and the restructuring of graduate labour markets in southern europe in this article we investigate whether education job mismatches and growing occupational diversity are important explanatory factors of gender pay gaps amongst university graduates in southern europe namely in portugal spain and italy we use standard decomposition techniques and test the implications of controlling for selection bias our results indicate that over education and greater occupational segregation associated with the emergence of new graduate job profiles are important determinants of earnings inequality whilst our focus is on graduates early careers demonstrating that occupational assignment and selection into employment shape gender pay gaps amongst the highly skilled provides a more pessimistic view on the ability of educational expansion or equal pay legislation to significantly reduce gender pay inequality southern european economies are also particularly interesting to look at since there may be a greater degree of mismatch between the pace of higher education expansion and the changes in the job structure making women particularly vulnerable to over education

the effectiveness of incomplete and overlapping pollution regulation evidence from bans on phosphate in automatic dishwasher detergent abstract this paper examines the effectiveness of command and control policies in the presence of incomplete and overlapping regulations we study how recent bans on phosphate in household dishwasher detergent affect pollution loads to waterways costs at wastewater treatment facilities and consumer behavior we show that the effectiveness of the bans in reducing effluent depends critically on regulations at receiving treatment facilities as cost minimizers facilities with an emissions standard on phosphorus face no incentive to deviate from the standard we show that bans have weak effects on effluent especially in the most polluted waterways we also use an early isolated ban in spokane washington to study the effect of the bans on consumers we find that this ban shifted approximately 40 of dishwasher detergent sales from spokane to bordering counties until a state wide ban was implemented using these estimates we find that the welfare loss to consumers from recent bans is likely greater than the cost savings to treatment plants

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
