two sample nonparametric estimation of intergenerational income mobility in the united states and sweden we estimate intergenerational income mobility in the us and sweden using a new nonparametric approach the approach addresses several empirical issues raised in the literature and applies when other estimators are infeasible we argue that previous estimates of income mobility conceal the heterogeneous nature of the transmission mechanism by keeping mobility constant across families the striking differences we find between mobility patterns across family backgrounds captured by father s education lead us to question the conventional result that intergenerational transmission of earnings is weaker in sweden than in the united states for important parts of the population

language and the earnings of immigrants several studies most of them employing straightforward regression analysis have concluded that immigrants proficiency in the language of their adopted country is correlated with their productivity as measured by earnings two weaknesses of these studies are potential unobserved heterogeneity which could result in over estimated effects if overall ability is linked with language acquisition and potential measurement error in the language proficiency measures which would probably result in under estimation of language effects the present study which uses panel data for a 10 year period in germany yields evidence that the latter bias tends to be much larger than the former implying that language proficiency is far more important than suggested by the existing literature

intergenerational economic mobility in the united states 1940 to 2000 we estimate trends in intergenerational economic mobility by matching men in the census to synthetic parents in the prior generation we find that mobility increased from 1950 to 1980 but has declined sharply since 1980 while our estimator places greater weight on location effects than the standard intergenerational coefficient the size of the bias appears to be small our preferred results suggest that earnings are regressing to the mean more slowly now than at any time since world war ii causing economic differences between families to become more persistent however current rates of positional mobility appear historically normal

state dependent pricing and the dynamics of money and output standard macroeconomic models of price stickiness assume that each firm leaves its price unchanged for a fixed amount of time we present an alternative model in which the pricing decision depends on the state of the economy we find a method of aggregating individual price changes that allows a simple characterization of macroeconomic variables the model produces a positive money output correlation and an empirical phillips curve in addition the impact of monetary shocks depends crucially on the current level of output which points to a natural connection between state dependent microeconomics and state dependent macroeconomics i introduction there is a long tradition in macroeconomics of attributing the real effects of nominal demand shocks to nominal price stickiness in this view if there is no change in prices when nominal demand rises then quantities must bear the burden of adjustment hence nominal price rigidity provides the friction needed for nominal demand shocks to be transmitted to the real economy standard models of this transmission mechanism such as fischer 1977 and taylor 1980 are based on the assumption that each firm leaves its price unchanged for a fixed amount of time the main reason for considering such time dependent pricing rules is their analytic tractability constraining firms to adjust their prices at prespecified times both simplifies the derivation of equilibrium strategies and allows the use of powerful time series techniques to analyze aggregate dynamics the main disadvantage of the timedependent approach is that between price adjustments firms are not allowed to respond even to extreme changes of circumstance this makes it difficult to know whether the qualitative effects of money in these models are the result of nominal rigidities per se or of the exogenously imposed pattern of price changes an alternative approach to modeling price stickiness is to allow the price setting decision to depend on the actual state of the

early decision and financial aid competition among need blind colleges and universities abstract this paper presents a stylized theoretical model of competition among need blind colleges and universities that implement early decision admissions under need blind admissions an applicant s financial aid status cannot affect their likelihood of admission in the model a need blind school can use early decision admissions as a screening mechanism to indirectly identify a student s ability to pay while superficially maintaining a need blind policy as a result in equilibrium non financial aid students are more likely to be admitted than financial aid students of comparable quality

an alternative measure of intergenerational income mobility based on a random coefficient model summary we propose an alternative measure of the degree to which income status is transmitted from one generation to another our indicator of intergenerational income mobility is based on a random coefficient model which allows for variation in intergenerational mobility across families due to multiplicative unobserved family specific characteristics this alternative measure suggests that intergenerational income persistence is typically stronger than when intergenerational income mobility is measured using the standard elasticity of sons income with respect to fathers income copyright 2011 john wiley sons ltd

notes on the theory and evidence on aggregate purchases of durable goods the basic implications of the frictionless permanent income hypothesis for durable goods purchases are strongly rejected by the data at the aggregate level there is too much inertia at the macroeconomic level purchases are too infrequent and lumpy in principle these rejections can be simultaneously rationalized by the presence of fixed costs of adjustment at the microeconomic level this article provides a simplified overview of recent developments attempting to formalize and measure the implications of models of fixed cost of adjustment for microeconomic and especially aggregate behavior of expenditure on durable goods it contends that these efforts have paid off in terms of methodological and empirical improvements copyright 1994 by oxford university press

slipping into and out of poverty the dynamics of spells this paper examines the dynamics of poverty previous analyses have examined either fluctuations in the male heads earnings or the frequency of poverty periods over a fixed time frame our approach depends on a definition of spells of poverty using this methodology we find that the majority of poor persons at any time are in the midst of a rather long spell of poverty the methodology also allows us to estimate that less than 40 percent of poverty spells begin because of a drop in the heads earnings while 60 percent of the spells end when the heads earnings increase thus researchers must focus on household formation decisions and on the behavior of secondary family members there has been a dramatic resurgence recently of discussion of the underclass the discussion is reminiscent of debates about poverty during the 1960s when the notions of a culture of poverty particularly as popularized by michael harrington s other america 1962 dominated both intellectual and policy thinking the idea of an underclass seems inconsistent however with much of the research on the dynamics of poverty during the 1970s that research using new longitudinal data seemed to show that the bulk of the poor were poor for only a few years the research also showed that the poor were a very heterogeneous group including a small minority of persistently poor the persistence of poverty is of interest both for understanding the phenomenon and for developing policy claims about dependency and separate life styles among the poor rest on assumptions about the long term nature of poverty questions

trends in intergenerational income mobility previous studies of recent u s trends in intergenerational income mobility have produced widely varying results partly because of large sampling errors by making more efficient use of the available information in the panel study of income dynamics we generate more reliable estimates of the recent time series variation in intergenerational mobility our results which pertain to the cohorts born between 1952 and 1975 do not reveal major changes in intergenerational mobility

centralization fiscal federalism and private school attendance a cge model is used to analyze the impact of public school financing on private school attendance the common perception that public school finance centralization will necessarily lead to greater private school attendance is not correct in such a model even when that centralization involves an extreme equalization as in california furthermore if centralization is less dramatic as in most states declines in private school attendance are even more pronounced this weakens the speculation that low exit rates to private schools in centralizing states imply that general public school quality does not drop as a result of such centralization

partial adjustment without apology econometric partial adjustment models perform relatively well at the aggregate level however many kinds of microeconomic behavior involve discrete and occasional choices analyzing the classic employment adjustment problem we show how a generalized partial adjustment model tractably accommodates both observations by aggregating the actions of heterogeneous producers facing fixed adjustment costs aggregate disturbances cause changes in establishment level target employment and in the measure of establishments actively adjusting to their target whereas aggregate responses exhibit partial adjustment our framework also can be applied in general equilibrium settings with persistent idiosyncratic shocks without forfeiting the convenient use of linear solution methods

biases in standard measures of intergenerational income dependence abstract estimates of the most common mobility measure the intergenerational elasticity can be severely biased if snapshots are used to approximate lifetime income however little is known about biases in other popular dependence measures using long swedish income series we provide such evidence for log linear and rank correlations and rank based transition probabilities attenuation bias is considerably weaker in rank based measures life cycle bias is strongest in the elasticity moderate in log linear correlations and small in rank based measures however there are important exceptions persistence in the tails of the distribution is considerably higher and long distance downward mobility lower than estimates from short run income suggest

durable goods an explanation for their slow adjustment at the microeconomic level durable purchases are often discontinuous and relatively large this feature has the potential to explain why aggregate expenditure on durables responds only slowly relative to the frictionless permanent income model to wealth and other aggregate innovations in this paper i develop new results on the problem of dynamic aggregation of stochastically heterogeneous units which help to characterize the connection between microeconomic behavior and aggregate dynamics in the presence of nonconvex adjustment costs using these results and splitting postwar u s aggregate durable purchases into different subcategories and time periods i provide further support for the view that lumpy microeconomic purchases play an important role in explaining the time series behavior of aggregate expenditure on durable goods

nonlinearities in intergenerational earnings mobility consequences for cross country comparisons we show that the patterns of intergenerational earnings mobility in denmark finland and norway unlike those for the us and the uk are highly nonlinear the nordic relationship between log earnings of sons and fathers is flat in the lower segments of the fathers earnings distribution sons growing up in the poorest households have the same adult earnings prospects as sons in moderately poor households and is increasingly positive in middle and upper segments this convex pattern contrasts sharply with our findings for the us and the uk where the relationship is much closer to being linear as a result cross country comparisons of intergenerational earnings elasticities may be misleading with respect to transmission mechanisms in the central parts of the earnings distribution and uninformative in the tails of the distribution it is now a stylised fact that intergenerational earnings mobility is higher in the nordic welfare state economies than in more market oriented economies such as the us see

microeconomic rigidities and aggregate price dynamics abstract this paper is an attempt to enrich the characterization of the sluggish behavior of the aggregate price level our contribution to this vast literature is to explicitly consider microeconomic heterogeneity and its interaction with nonlinear microeconomic price adjustment policies the model we propose outperforms the constant probability of adjustment partial adjustment model in describing the path of postwar u s inflation using only aggregate data we infer that the probability that a firm adjusts its price depends on the sign and the magnitude of the deviation of the price from its target level at the aggregate level we find that the aggregate price level responds less to negative shocks than to positive shocks that the size of this asymmetry increases with the size of the shock and that the number of firms changing their prices and therefore the flexibility of the price level to aggregate shocks varies endogenously over time in response to changes in economic conditions

electricity demand in kazakhstan properties of electricity demand in transition economies have not been sufficiently well researched mostly due to data limitations however information on the properties of electricity demand is necessary for policy makers to evaluate effects of price changes on different consumers and obtain demand forecasts for capacity planning this study estimates kazakhstan s aggregate demand for electricity as well as electricity demand in the industrial service and residential sectors using regional data firstly our results show that price elasticity of demand in all sectors is low this fact suggests that there is considerable room for price increases necessary to finance generation and distribution system upgrading secondly we find that income elasticity of demand in the aggregate and all sectoral models is less than unity of the three sectors electricity demand in the residential sector has the lowest income elasticity this result indicates that policy initiatives to secure affordability of electricity consumption to lower income residential consumers may be required finally our forecast shows that electricity demand may grow at either 3 or 5 per year depending on rates of economic growth and government policy regarding price increases and promotion of efficiency we find that planned supply increases would be sufficient to cover growing demand only if real electricity prices start to increase toward long run cost recovery levels and policy measures are implemented to maintain the current high growth of electricity efficiency

pay as you go social security and the distribution of altruistic transfers this paper studies the impact of an unfunded social security system on the distribution of altruistic transfers in a framework where savings are due to both life cycle and random altruistic motivations we show that the effect of social security on the distribution of these transfers depends crucially on the strength of the bequest motive in explaining savings behaviour we measure this strength by the expected weight that individuals attach to the utility of future generations on the one hand if the bequest motive is strong then an increase in the social security tax raises the bequests left by altruistic parents on the other hand when the importance of altruism in motivating savings is sufficiently low the increase in the social security tax could result in a reduction of the bequests left by altruistic parents under some conditions on the attitude of individuals toward risk and on the relative returns associated with private saving and social security some implications concerning the transitional effects of introducing an unfunded social security scheme are also discussed

does education expansion increase intergenerational mobility education expansion may lead to over education where the social connections of parents may exert more significant influence on the return to education of children with the assumption of a positive correlation between return on human capital and parental income in the presence of over education we show that i the expansion of education may cause horizontal inequity in education opportunities and inefficiency in human capital accumulation ii the positive correlation between return on human capital and parental income causes a more persistent intergenerational immobility iii an expansion of education especially higher education leads to more persistent intergenerational immobility

a theory of managed trade this paper proposes a theory that predicts low levels of protection during periods of normal trade volume coupled with episodes of special protection when trade volumes surge this dynamic pattern of protection emerges from a model in which countries choose levels of protection in a repeated game facing volatile trade swings high trade volume leads to a greater incentive to defect unilaterally from cooperative tariff levels therefore as the volume of trade expands the level of protection must rise in a cooperative equilibrium to mitigate the rising trade volume and hold the incentive to defect in check copyright 1990 by american economic association

harmonization of commodity taxes destination origin and restricted origin principles abstract the three tax principles are compared using a multiproduct custom union model it is shown that if member countries use the destination or origin principles no distortion or redistribution of income occurs even if their tax rates differ however under the restricted origin principle different tax rates result in distortion and income redistribution equal tax rates still result in a redistribution of real income an exact measurement of this redistribution is derived given these results it seems possible to conclude that the origin principle is superior to the other tax principles

regression toward mediocrity in economic stature this paper provides estimates of the correlation in lifetime earnings between fathers and sons intergenerational data from the national longitudinal survey are used earlier studies conducted for the united states report elasticities of children s earnings with respect to parent s earnings of 0 2 or less suggesting extensive integenerational mobility these estimates however are biased downward by error contaminated measures of lifetime economic status estimates presented in this paper correct for the problem of measurement error and find the intergenerational correlation in income to be on the order of 0 4 this suggests considerably less intergenerational mobility than previously believed jel j62

intergenerational income mobility in the united states social scientists and policy analysts have long expressed concern about the extent of intergenerational income mobility in the united states but remarkably little empirical evidence is available the few existing estimates of the intergenerational correlation in income have been biased downward by measurement error unrepresentative samples or both new estimates based on intergenerational data from the panel study of income dynamics imply that the intergenerational correlation in long run income is at least 0 4 indicating dramatically less mobility than suggested by earlier research copyright 1992 by american economic association

intergenerational earnings mobility in norway levels and trends using longitudinal data for norwegian children born in 1950 1955 1960 and 1965 we find a relatively high degree of earnings mobility there is no tendency toward decreasing mobility over the cohorts conditioning on the position in the earnings distribution the analysis indicates quite high mobility in the middle of the distribution and somewhat more persistence at the top and bottom this approach also reveals increased mobility over time for sons but a less clear picture for daughters

the cross sectional dynamics of the us business cycle 1950 1999 abstract modern interest in business cycles has focussed on the co movements and correlations in the major macroeconomic aggregates in this paper we offer another dimension to business cycle analysis which looks at the time series of cross sectional distributions of the growth rates of sales by us quoted companies from 1950 to 1999 we detect correlations between aggregate business cycle fluctuations and the higher moments of the cross sectional distribution we find a significant negative correlation between the rate of growth of gdp and the cross sectional variance and skewness of growth rates of sales on the other hand there is positive correlation at business cycle frequencies with kurtosis in order to explore this further we turn to the dynamic evolution of firms and analyse the sensitivity of growth rates to aggregate shocks conditioning on firm size the results suggest that despite considerable heterogeneity macroeconomic shocks have pervasive effects that are however more pronounced for firms in the middle range of growth this has implications for both macro and industrial economics

economic interpretations of intergenerational correlations science itself for example see galton s 1869 study of the eminence of relatives or his 1889 analysis of the heights of parents and children but extensive use of economic theory to interpret these correlations is much more recent using basic economic concepts such as supply demand investment incentives missing markets and so on theorists hope to explain how and why status is correlated across generations economic theory might provide a unified treatment of a variety of socioeconomic indicators such as earnings income occupation or wealth or it might predict how taxes subsidies and economic regulation affect intergenerational mobility and the operation of markets however while the subject matter earnings consumption wealth occupa tion is clearly interesting to economists it could nonetheless be the case that beyond basic questions of measurement economic theory has not improved our understanding of intergenerational mobility goldberger 1989 is quite explicit in this contention by emphasizing the distinction between genes and environment and by using statistical theory as its main analytical tool the paper by samuel bowles and herbert gintis in this issue implicitly concurs with goldberger we take this challenge very seriously what characterizes an economic approach to mobility while biologists and bowles and gintis distinguish endowments and investments by their source genetic versus environmental factors one focus of economic theorists is motiva

fortunate sons new estimates of intergenerational mobility in the united states using social security earnings data previous studies relying on short term averages of fathers earnings have estimated the intergenerational elasticity ige in earnings to be approximately 0 4 due to persistent transitory fluctuations these estimates have been biased down by approximately 30 or more using administrative data containing the earnings histories of parents and children the ige is estimated to be around 0 6 this suggests that the united states is substantially less mobile than previous research indicated estimates of intergenerational mobility are significantly lower for families with little or no wealth offering empirical support for theoretical models that predict differences due to borrowing constraints

the role of the urban non urban cost of living difference in measured intergenerational earnings mobility abstract in light of a substantial compensating urban non urban wage gap a documented strong intergenerational persistence of urbanicity could produce a higher intergenerational association in nominal than in real earnings controlling interarea cost of living differences i find that the estimated elasticity for real earnings is less to a statistically significant degree

how important is human capital a quantitative theory assessment of world income inequality we develop a quantitative theory of human capital investment in order to evaluate the magnitude of cross country dierences in total factor productivity tfp that explains the variation in per capita incomes across countries we build a heterogeneousagent economy with cross sectional variation in ability schooling and expenditures on schooling quality in our theory the parameters governing human capital production and random ability process have important implications for a set of cross sectional statistics mincer return variance of earnings variance of schooling and intergenerational correlation of earnings these restrictions of the theory and u s household data are used to pin down the key parameters driving the quantitative implications of the theory our main finding is that human capital accumulation strongly amplifies tfp dierences across countries in particular we find an elasticity of output per worker with respect to tfp of 2 8 a 3 fold dierence in tfp explains a 20 fold dierence in output per worker we argue that the cross country dierences in human capital implied by the theory are consistent with a wide array of evidence including earnings of immigrants in the united states average mincer returns across countries and the relationship between average years of schooling and per capita income across countries the theory implies that using mincer returns to measure human capital understates dierences across countries by a factor of 2

tariff retaliation from a strategic viewpoint one of the most perplexing questions in international trade concerns the rationale for the existence of widespread barriers to trade in the current world economy 1 the numerous explanations that have been offered for the existence of tariffs are generally based on one of the following four arguments a the existence of market imperfections monopolies externalities etc invalidates the free trade theorem and thus free trade is not desirable or perhaps not obtainable b sluggish adjustment of the world economy to free trade implies that the existing tariffs are a temporary phase c non economic phenomena such as nationalism induce political or institutional tariff arrangements or d protectionist motives to improve the welfare of a country or a group of individuals in that country induce all countries to simultaneously impose tariffs while all of these factors can be important in the explanation of the existence of tariffs the purpose of this paper is to develop an extended analysis of the protectionist view the protectionist view is based on the optimal tariff theorem which states under very restrictive assumptions that a country can improve its welfare by imposing a tariff 5 12 a serious difficulty with this explanation is that the optimal tariff theorem assumes that no retaliation occurs as scitovsky 12 points out a country that could benefit from charging a tariff has monopoly power in trade surely a country sophisticated enough to exercise monopoly power in trade would expect its rivals to respond when tariffs are erected hence scitovsky argues that if protection is the monopolistic behavior of a collectivity two countries raising tariffs against each other are bilateral monopolists and we know that bilateral monopoly results in the two parties coming to some working agreement whose terms depend on their bargaining skill and are analytically indeterminate scitovsky concluded that a tariff war would result in an indeterminate solution with both countries worse off johnson 6 formalized scitovsky s agrument by allowing each country to adopt a cournot type assumption regarding its rival s reaction to a change in its own tariff thus

intergenerational persistence of earnings the role of early and college education recent empirical evidence from the united states indicates a high degree of persistence in earnings across generations designing effective public policies to increase social mobility requires identifying and measuring the major sources of persistence and inequality in earnings we provide a quantitative model of intergenerational human capital transmission that focuses on three sources innate ability early education and college education we find that approximately one half of the intergenerational correlation in earnings is accounted for by parental investment in education in particular early education we show that these results have important implications for education policy

a conjectural variation approach to strategic tariff equilibria abstract this paper examines tariff equilibria in a static two country trade model under a general class of conjectures regarding foreign retaliation we assume that each country chooses its optimum tariff given some conjecture in this class and derive the associated conjectural tariff equilibrium which can be thought of as a nash equilibrium conditional on each country s conjecture about how the foreign country will retaliate our main contribution is to show that when marginal propensities to consume imports are sufficiently small increased expectation of retaliation results in lower equilibrium tariffs for both countries since countries in general probably do expect some retaliation it therefore appears that the traditional cournot nash analysis probably overstates the trade restrictiveness of tariff wars

family economics and macro behavior in this 1987 presidential address to the american economic association the author explores the contributions of the field of family economics to macroeconomic analysis the focus is on family behavior as an active endogenous factor that both affects and is affected by the evolution of the economy much of the time is spent on long term economic growth although i also discuss short and long cycles in economic activity and the interaction between overlapping generations through social security transmission of inequality and in other ways many conclusions in these and presumably other macro areas change radically when family choices get the attention they deserve excerpt

unobservable family and individual contributions to the distributions of income and wealth this paper uses combinations of full brothers half brothers and fathers and sons to measure the effect of common family background on a household s income and wealth while the data are drawn from a nineteenth century population the intraclass correlation for income ranges from 13 to 18 which is similar to that found in modern samples intraclass correlations for wealth are significantly higher 18 35 than are those for income intraclass correlations of half brothers compared to those for full brothers suggest that fathers play a dominant role in the transmission of the common family effect when unobserved background is decomposed into individual and family effects the individual effect dominates the family effect for income while the family effect dominates the individual effect for wealth

parental wealth and adult children s welfare in marriage abstract many studies find that parental resources importantly determine children s human capital schooling returns and earnings the collective household approach suggests that in addition parental resources of marital partners may importantly affect resource distributions within marriage this paper presents empirical results consistent with this framework they suggest that parental wealth continues to play roles in augmenting welfare of children into adulthood beyond provision of human capital in early life cycle stages or direct financial aid during adulthood and that actual transfers from parents to adult children do not fully measure influences of parental wealth on behaviors and welfare of adult children

more equal but less mobile education financing and intergenerational mobility in italy and in the us a centralised and egalitarian school system reduces the cost of education for poor families and so it should reduce income inequality and make intergenerational mobility easier in this paper we provide evidence that italy compared to the usa displays less income inequality as expected given the type of school system but also less intergenera tional upward mobility between occupations and between education levels we explore some of the reasons which can explain this puzzling result and conclude that in a world in which family background is important for labor market success a centralised and egalitarian tertiary education does not necessarily help poor children and may take away from them a fundamental tool to prove their talent and to compete with rich children 1999 elsevier science s a all rights reserved

patterns of intergenerational mobility in income and earnings this paper characterizes the patterns of intergenerational mobility in the united states using data for matched parent child pairs from the national longitudinal surveys in general what is found is far from the extremes of either perfect mobility or perfect immobility parents log income explains only about 9 percent to 11 percent of the variation in children s log incomes earnings exhibit more mobility than does total income and the difference is most striking for daughters the paper also identifies the influence of family background characteristics on mobility the addition of these background variables adds another 3 to 5 percent age points to the r2 in the intergenerational earnings and income regressions copyright 1992 by mit press

microeconomic adjustment hazards and aggregate dynamics the basic premise of this paper is that understanding aggregate dynamics requires considering that agents are heterogeneous and that they do not adjust continuously to the shocks they perceive we provide a general characterization of lumpy behavior at the microeconomic level in terms of an adjustment hazard function which relates the probability that a unit adjusts to the deviation of its state variable from its moving target we characterize rich cross sectionally dependent aggregate dynamics generated by nonconstant hazards we present an example based on u s manufacturing employment and job flows and find that increasinghazard models outperform constant hazard partial adjustment models in describing aggregate employment dynamics

snapshots versus movies empirical studies of the intergenerational inheritance of economic status should use observations on complete lifetime status profiles of parents and children to be consistent with underlying theory but they cannot only snapshots rather than movies on status are currently available in samples estimates of the degree of intergenerational inheritance may therefore be subject to lifecycle biases the paper investigates these in the context of a lifecycle earnings model and shows that these biases may be large that their direction varies and that correction methods suggested hitherto have questionable reliability until more complete data sets become available researchers should be more temperate in the conclusions they draw

country bashing tariffs do bilateral trade deficits matter abstract this paper investigates the impact of restricting bilateral trade imbalances in a three country three good model bilateral trade balances matter because in the nash equilibrium each country will impose tariffs on countries with whom they have bilateral deficits or promote trade with countries with whom they have bilateral surpluses all countries lose from a nash country bashing war each country loses from the unilateral elimination of its bilateral imbalances but a country can gain from a bilateral agreement with its deficit partner provided that country has a surplus with a country devoted to free trade

inflation stabilisation and the consumption of durable goods exchange rate based stabilisations in chronic inflation countries have often been characterised by an initial consumption boom which is most evident in the behaviour of durable goods followed by a later contraction this paper provides an explanation for such a boom recession cycle based on the timing of purchases of durable goods the initial fall in inflation results in a wealth effect which induces many consumers to bring forward their purchases of durable goods thus generating an aggregate consumption boom since most consumers replenish their stock of durable goods at the beginning of the programme a later slowdown follows

intellectual property rights in china the changing political economy of chinese american interests we review the evolution of modern chinese intellectual property right ipr laws and enforcement and explore economic and political forces involved in international conflicts over chinese ipr protection our analysis considers why the us and china moved from conflict to cooperation over intellectual property rights structural and institutional aspects of the political economy of iprs within each country are considered and data on chinese us trade in intellectual property intensive goods are examined we conclude that although enforcement of iprs within china continues to be relatively weak chinese ipr institutions are converging on those in the oecd nations

intergenerational health mobility an empirical approach based on the echp despite the importance of the study of health mobility few attempts have been made to measure intergenerational mobility not only in the european union but also in other countries such as united states this article is focused on the study of intergenerational health mobility using data from the european community household panel echp in particular the relationships between self assessed health of parents and their sons are analysed the evidence obtained suggests that in spain sons reported health depends significantly on the self assessed health of their fathers

the business cycle macroeconomic shocks and the cross section the growth of uk quoted companies we bring to light a significant aspect of firm level heterogeneity over the business cycle analysing the responsiveness of firm growth quoted uk companies to aggregate shocks we find that the effects of aggregate shocks are more pronounced for firms in the middle range of growth rapidly growing and rapidly declining firms are less sensitive to aggregate shocks than firms in the interior of the growth range this is consistent with the fact that the higher moments of the distribution of firm growth rates have significant cyclical patterns these findings throw new light on growth of firms as well as on business cycle dynamics

trade deflection trade distortions and pareto inefficiencies under the restricted origin principle abstract this paper shows that trade deflection is not the administrative aspect of the restricted origin principle as suggested in the literature but an important analytical issue that bears on resource allocation when deflection is taken into account trade distortions are avoided only when either domestic or at least border tax adjustment rates are equal in the member countries and trade balances are in bilateral equilibrium the control of deflection via rules of destination causes trade distortions and sometimes pareto inefficiencies the paper further shows that when the vat is calculated according to the credit method and trade is conducted by registered traders trade distortions are prevented when tax rates are set in inverse relation to bilateral trade balances

the political economy of intergenerational income mobility the intergenerational elasticity of income is considered one of the best measures of the degree to which a society gives equal opportunity to its members while much research has been devoted to measuring this reduced form parameter less is known about its underlying structural determinants using a model with exogenous talent endowments endogenous parental investment in children and endogenous redistributive institutions we identify the structural parameters that govern the intergenerational elasticity of income the model clarifies how the interaction between private and collective decisions determines the equilibrium level of social mobility two societies with similar economic and biological fundamentals may have vastly different degrees of intergenerational mobility depending on their political institutions we offer empirical evidence in line with the predictions of the model we conclude that international comparisons of intergenerational elasticity of income are not particularly informative about fairness without taking into account differences in politico economic institutions jel e24 j62 j68 p16

an exogeneity test for a simultaneous equation tobit model with an application to labor supply a test of weak exogeneity in the simultaneous equation tobit model is proposed and illustrated using a female labour supply model estimated using cross section data the test statistic can be simply output from any standard tobit maximum likelihood package and is asymptotically efficient the procedure provides consistent estimators for the simultaneous tobit model whose asymptotic covariance matrix is a simple extension of the usual tobit formula we also provide the lagrange multiplier test of weak exogeneity this abstract was borrowed from another version of this item
