winners and losers in housing markets this paper is a quantitatively oriented theoretical study into the interaction between housing prices aggregate production and household behaviour over a lifetime we develop a life cycle model of a production economy in which land and capital are used to build residential and commercial structures we find that in an economy where the share of land in the value of structures is large housing prices react more to an exogenous change in expected productivity or the world interest rate causing large redistribution effects between net buyers and net sellers of houses changing the financing constraint however has limited effects on housing prices

if we knew ability how would we tax individuals abstract the suggestion to tax people on earnings capacity instead of earnings has been around for a long time and is attractive in terms of economic efficiency in this paper we reflect on the feasibility of such a system and give an exploratory empirical implementation we apply the leyden welfare function of income a survey based measure of an individual s welfare associated with income to derive implications for ability taxation under the assumption that iq and schooling reflect earnings capacity we derive the tax functions using different criteria to distribute the utility loss due to taxation

the ins and outs of european unemployment in this paper we study the contribution of inflows and outflows to the dynamics of unemployment in three european countries the united kingdom france and spain all countries are interesting in their own right and in the comparison with each other britain s labour markets were strictly regulated up to the mid 1980s but they have been liberalized since then france is still a regulated economy compared with britain with unemployment averaging about 8 spain has had the biggest rise in unemployment in europe reaching 24 in the mid 1990s but policy reforms and fast growth since then brought it down to a level below france s we compare performance in these three countries making use of both administrative and labor force survey data we find that the impact of the 1980s reforms in britain is evident in the contributions of the inflow and outflow rates the inflow rate became a bigger contributor after the mid 1980s although its significance subsided again in the late 1990s and 2000s in france the dynamics of unemployment are driven by the outflow rate virtually entirely which is consistent with a regime with strict employment protection legislation in spain however both rates contribute significantly to the dynamics perhaps as a consequence of the prominence of fixed term contracts since the late 1980s

household cost functions and equivalence scales we describe a simple method to estimate household cost functions and family equivalence scales it is an alternative to standard methods as it does not assume strong postulates about utility maximization nor any functionally specified model equations the data requirements are extremely modest we assume interpersonal ordinal comparability in the sense of sen 1976 and use empirical evidence for eight european countries and the u s to show the feasibility of the method and the stability of its results we also show that subjective data like those provided by income evaluation questions may be used without adopting a cardinal utility framework

consumer demand and the life cycle allocation of household expenditures the purpose of this paper is to estimate the parameters of household preferences that determine the allocation of goods within the period and over the life cycle using micro data in doing so the authors are able to identify important effects of demographics labor market status and other household characteristics on the intertemporal allocation of expenditure they test the validity of the life cycle model using excess sensitivity tests and find that controlling for demographics and labor market status variables can largely explain the excess sensitivity of consumption to anticipated changes in income

valuing lost home production of dual earner couples using a life cycle model in which women divide their time between home and market work we establish a link between retirement wealth and the value of forgone home production we use data from the health and retirement study to estimate the model s parameters and adjust the growth rate of gdp to reflect reductions in non market output we find that the value of forgone home production is modest about 25 percent of women s measured earnings

corporate taxation in the oecd in a wider context against the background of increased globalisation statutory corporate tax rates have shown a clear downward trend over the last two decades the sharp decline in these rates was accompanied by substantial tax base broadening and a comparable reduction in personal income tax rates only until the early 1990s this suggests that corporate tax competition is of increasing importance so far corporate tax revenues remain fairly stable but an analysis of corporate taxation in the context of the overall tax systems shows that a substantial shift towards value added taxes has taken place while the trends so far have been driven by smaller european countries recent tax reforms indicate that increasing tax competition is inducing a shift towards consumption even for larger economies

how sensible is the leyden individual welfare function of income a reply abstract in this paper we react to seidl s 1994 critique on the leyden approach our conclusion is that seidl s critique is ill founded as a serious critique on the leyden approach

on measuring child costs with applications to poor countries the theoretical basis for measuring child costs is discussed and detailed consideration is given to two straightforward procedures for calculation engel s food share method and rothbarth s adult good method each of these methods embodies different definitions of child costs so that the same empirical evidence can generate quite different estimates depending on the method used it is shown that true costs are generally overstated by engel s method and understated by rothbarth s procedure although the latter unlike the former can provide a sensible starting point for cost measurement our estimates from sri lankan and indonesian data suggest that children cost their parents about 30 40 percent of what they spend on themselves

how sensible is the leyden individual welfare function of income abstract the leyden economists contend that the individual welfare function utility function of income is best represented by a lognormal distribution function they have presented ample data to document the good empirical fit of the lognormal hypothesis this paper presents reexamines and criticises the theoretical foundations of the lognormal hypothesis and finds that this edifice is not built on solid ground neither from the point of view of economic theory nor of experimental psychology moreover it investigates the paradox of the good empirical fit of the lognormal hypothesis in spite of its theoretical deficiencies it is shown that the lognormal hypothesis is observationally equivalent to the logarithmic power welfare function when respondents evaluate welfare according to a normal lognormal distribution function

relativity rank and the utility of income relative utility has become an important concept in several disjoint areas of economics i present a cardinal model of income utility based on the supposition that agents care about their rank in the income distribution and that utility is subject to adaptation over time utility levels correspond to the leyden individual welfare function while utility differences yield a version of the prospect theory value function thereby providing a new and shared derivation of each i offer an explanation of some long standing paradoxes in the wellbeing literature and an insight into the links between relative comparisons and loss aversion

the cyclicality of separation and job finding rates this paper uses cps gross flow data to analyze the business cycle dynamics of separation and job finding rates and to quantify their contributions to overall unemployment variability cyclical changes in the separation rate are negatively correlated with changes in productivity and move contemporaneously with them while the job finding rate is positively correlated with and tends to lag productivity contemporaneous fluctuations in the separation rate explain between 40 and 50 percent of fluctuations in unemployment depending on how the data are detrended this figure becomes larger when dynamic interactions between the separation and job finding rates are considered

u s tax policy and health insurance demand can a regressive policy improve welfare abstract the u s tax policy on health insurance is regressive because it subsidizes only those offered group insurance through their employers who also tend to have a relatively high income moreover the subsidy takes the form of deductions from the progressive income tax system giving high income earners a larger subsidy to understand the effect of the policy we construct a dynamic general equilibrium model with heterogenous agents and an endogenous demand for health insurance a complete removal of the subsidy may lead to a partial collapse of the group insurance market reduce the insurance coverage and deteriorate welfare there is however room for improving the coverage and welfare by extending a refundable credit to the individual insurance market

estimating earnings poverty in 1939 a comparison of orshansky method and price indexed definitions of poverty official poverty lines do not exist for the united states for years prior to 1959 in this paper a poverty line comparable to the seminal line is constructed for 1939 using the orshansky method poverty rates are then calculated using the earnings data of the 1940 public use microdata sample of the u s census a comparison with similar work by ross et al 1987 demonstrates the degree to which continual price indexing of the poverty line results in inappropriate estimates a trend of increasing incidence of poverty among female headed households prior to 1960 is also revealed

endogenous debt constraints in a life cycle model with an application to social security this paper develops a simple life cycle model that embeds a theory of debt restrictions based on the existence of inalienable property rights a la kehoe and levine 1993 debt constrained asset markets review of economic studies 60 4 865 888 2001 liquidity constrained markets versus debt constrained markets econometrica 69 3 575 598 in our environment net debtors have the option of defaulting on unsecured debt at the cost of being subjected to wage garnishment and or having some or all of their future assets seized by creditors one advantage of our framework is that it encompasses two standard versions of the life cycle model one with perfect capital markets and one with a non negative net worth restriction we study the impact of a payroll financed social security system to illustrate the role of endogenous debt constraints and compare our results to a model with exogenous debt constraints whereas the aggregate effects are similar under both types of constraints the distributional consequences are found to be significantly different across debt regimes

consumer bankruptcy a fresh start consumer bankruptcy provides partial insurance against bad luck but by driving up interest rates makes life cycle smoothing more difficult we argue that to assess this trade off one needs a quantitative model of consumer bankruptcy with three key features life cycle component idiosyncratic earnings uncertainty and expense uncertainty exogenous negative shocks to household balance sheets we find that transitory and persistent earnings shocks have very different implications for evaluating bankruptcy rules more persistent shocks make the bankruptcy option more desirable larger transitory shocks have the opposite effect our findings suggest the current us bankruptcy system may be desirable for reasonable parameter values jel d14 d91 k35

food security and health status in the united states food security is defined as access by all times to enough food for an active healthy life this paper explores the relationships between food security and women s self evaluated health status a theoretical model is developed which suggests that our primary interests can be served by estimating health and food security production functions we find that food security has a significant influence on a woman s self evaluated health status however the exact manifestations are difficult to quantify they may be psychological or physiolgical the most food insecure women tend to be poor and less educated tobacco use lack of physical exercise and obesity also weigh heavily good health status

climate equivalence scales an application of a general method abstract in this paper we investigate the dependency between household cost and climate conditions on the basis of a large european data set a climate index is constructed and a climate compensation scale is derived examples are given for european cities

do matching frictions explain unemployment not in bad times this paper models unemployment as the result of matching frictions and job rationing job rationing is a shortage of jobs arising naturally in an economic equilibrium from the combination of some wage rigidity and diminishing marginal returns to labor during recessions job rationing is acute driving the rise in unemployment whereas matching frictions contribute little to unemployment intuitively in recessions jobs are lacking the labor market is slack recruiting is easy and inexpensive so matching frictions do not matter much in a calibrated model cyclical fluctuations in the composition of unemployment are quantitatively large

returns to education a further international update and implications this paper updates evidence on the returns to investment in education by adding estimates for new countries and refining existing estimates to bring the total number of country cases to over 60 the new cross country evidence confirms and reinforces earlier patterns namely that returns are highest for primary education the general curricula the education of women and countries with the lowest per capita income the findings have important implications for directing future investment in education which for efficiency and equity purposes should concentrate on these priority areas

temptation and self control some evidence and applications this paper studies the empirical relevance of temptation and self control using household level data from the consumer expenditure survey we construct an infinite horizon consumption savings model that allows but does not require temptation and self control in preferences in the presence of temptation a wealth consumption ratio in addition to consumption growth becomes a determinant of the asset pricing kernel and the importance of this additional pricing factor depends on the strength of temptation to identify the presence of temptation we exploit an implication of the theory that a more tempted individual should be more likely to hold commitment assets such as individual retirement account ira or 401 k accounts our estimation provides empirical support for temptation preferences based on our estimates we explore some quantitative implications of this class of preferences for capital accumulation in a neoclassical growth model and the welfare cost of the business cycle

life insurance and household consumption abstract using life insurance holdings by age sex and marital status we infer how individuals value consumption in different demographic stages we estimate equivalence scales and bequest motives simultaneously within a fully specified model where agents face us demographics and save and purchase life insurance our findings indicate that individuals are very caring for dependents that economies of scale are large that children are very costly or yield very high marginal utility that wives with children produce lots of home goods and that females display habits from marriage while men do not these findings contrast sharply with standard equivalence scales

self rated economic welfare in russia abstract most of those russian adults who feel that they are poor are not classified as such in the poverty statistics and most of those who are classified as poor don t feel that way we study the determinants of peoples perceptions of their economic welfare in an unusually rich socioeconomic survey while income is a highly significant predictor subjective economic welfare is influenced by many other factors including health education employment assets relative income in the area of residence and expectations about future welfare insights are obtained into how objective data should be weighted in assessing economic welfare

on the marginal welfare cost of taxation this paper develops a rigorous partial equilibrium analysis of the determinants of margin al welfare cost mwc of taxes on labor earnings it shows that four key parameters interact to determine the magnitude of mwc using aggregate data and plausible ranges of values for the parameters mwc can vary from under 10 percent to more than 300 percent of marginal tax revenue intermediate parameter values sugge st mwc is in the 25 50 percent range however the more extreme estimates cannot be ruled out on the basis of available evidence suggesting that mwc cannot yet be copyright 1987 by american economic association

reverse mortgage loans a quantitative analysis reverse mortgage loans rmls allow older homeowners to borrow against housing wealth without moving despite rapid growth in this market only 1 9 of eligible homeowners had rmls in 2013 in this paper we analyze reverse mortgages in a calibrated life cycle model of retirement the average welfare gain from rmls is 252 per homeowner and 1 770 per rml borrower bequest motives uncertainty about health and expenses and loan costs account for low demand according to the model the great recession s impact differs across age income and wealth distributions with a threefold increase in rml demand for lowest income and oldest households

economies of scale and the volume of intra industry trade abstract using a model of monopolistic competition with traded and non traded goods this paper establishes a positive link between scale economies the volume of intra industry trade and the share of trade in total production these results are consistent with empirical findings

intertemporal consumption durables and liquidity constraints a cohort analysis we provide a theoretical framework to analyse the response of life time maximizing consumers to intertemporal prices of non durable goods and durable goods when the borrowing limit depends on the market value of the stock of durables owned by the consumer we use pseudo panel data on purchases of non durables and durable goods cars and demographic characteristics from the uk family expenditure survey as well as estimates of the durable stock constructed using the uk national travel survey to estimate the equations derived in the first part of the paper we evaluate the shadow prices of these restrictions which were significantly positive for younger consumers in the mid seventies and immediately prior to the 1982 financial liberalisation

rising inequality changes in the distribution of income and consumption in the 1980s this paper examines changes in the distribution of income and consumption in the united states during the 1980s using data from the current population survey income and consumer expenditure survey consumption we reach three primary conclusions first changes in the distribution of consumption parallel changes in the distribution of income the lowest quintile of the consumption distribution received 0 9 percentage points less of total consumption in 1988 than in 1980 the corresponding decline for income was 0 6 percentage points second broad conclusions concerning recent changes in the consumption distribution are not very sensitive to the exact choice of a measure of family needs under a wide variety of alternative household equivalence scales there is a widening in the consumption distribution in the 1980s third the usc of consumption measures of well being in place of measures based on current money income docs change conclusions concerning the extent of poverty in the united stales using the official federal poverty thresholds we find that the overall consumption poverty rate was three percentage points below the income poverty rate in 1988 comparisons of the poverty rates of the elderly and the non elderly are substantially affected by the choice of poverty measure the consumption poverty rare for the elderly was only 60 percent of the rate for adults and one third of the rate for children in 1988 this abstract was borrowed from another version of this item

evaluation of welfare functions of environmental amenities a case of forest biomass fuels in mount kilimanjaro tanzania abstract this study is an empirical investigation of welfare functions of forest biomass fuels in mount kilimanjaro tanzania the want parameter of welfare function was found to vary with household s current fuel consumption which reflects people s amenity aspirations shift with the amenity level attained furthermore current wood consumption and welfare sensitivity parameter are also influenced by individual s environmental entitlements rather than economic entitlements resource scarcity induced by physical scarcity or institutional legal constraints leads to resource conserving attitude but not without loss in perceived well being communal conservation of energy is also observed whereby large households are more energy conserving than small households regarding biomass use and consumption monetary income does not guarantee satisfaction but heightens people s wants thus rural development programs should not focus on economic empowerment only but also on environmental sustainability and fair resource use rules

family labor supply with taxes over the period 1960 1983 the proportion of federal tax revenue raised by taxation of labor supply has risen from 57 77 percent in this paper we specify and estimate a model of family labor supply which treats both federal and state taxation husbands and wives labor supply are treated jointly rather than in aseparate manner as in previous research a method to calculate the virtual wage for nonworking spouses is used within a utility maximizing framework to treat correctly the joint family labor supply decision joint family efforts are found to be important the efficiency cost deadweight loss of labor taxation is estimated to be 29 6 of tax revenue raised the effect of the new 10 deduction to ease the marriage tax for working spouses leads to a prediction of 3 8 increase in wives labor supply and a 9 decrease in husbands labor supply overall taxes paid are predicted to decrease by 3 4 this abstract was borrowed from another version of this item

humps and bumps in lifetime consumption in this article we argue that the life cycle model that allows demographics to affect household preferences and relaxes the assumption of certainty equivalence can generate hump shaped consumption profiles over age that are very similar to those observed in household level data sources and in particular match the differences in shape across different education groups liquidity constraints or myopia are not required to explain the empirical features of observed life cycle patterns

yours mine and ours do divorce laws affect the intertemporal behavior of married couples divorce laws establish spouses individual property rights over household resources and determine when divorce is allowed this paper examines how such laws inuence the intertemporal behavior and the welfare of u s married couples i build a model of household choice about consumption labor supply and divorce under multiple divorce law regimes and i estimate it using exogenous variation in u s divorce laws from the 1970s to the 1990s couples responded to equal division of property and unilateral divorce by increasing tangible assets up to 19 which suggests the presence of a strong income eect for the primary earner and by reducing female employment by over 5 percentage points because the threat of divorce granted additional bargaining power to married woman the bargaining weight of women implied by these responses in the model corresponds to a third of the weight of men this indicates that equal division of assets beneted women when it was

implementation of first best allocations via generalized tax schedules abstract the classical problem of optimal taxation introduced by j mirrlees rev econ stud 38 1971 175 208 is addressed and it is argued that by using generalized tax schedules i e schedules which depend not only on individual income but also on the whole profile of incomes announced by the society a planner can implement any pareto optimum which stands in great contrast with the set of second best pareto optima attainable via classical tax schedules the mechanism relies crucially on the fixed probability distribution of characteristics and on a finite number of agents journal of economic literature classification numbers d78 d82 h21

consumption technology and the intrafamily distribution of resources adult equivalence scales reexamined adult equivalence scales are supposed to measure differences in the needs of households of different demographic composition formally they purport to measure the change in the cost of attaining a certain welfare level when the family composition varies this paper shows that the definition and the measurement of these scales depend crucially on the concept of welfare used when welfare is the utility parents derive from their own consumption one has to assume separability of parents and children s consumption this assumption implies that the only way of imputing the intrafamily allocation of resources is by observing the consumption patterns of adult goods regardless of the definition used one cannot separate the factors reflecting home technology i e needs from those determining the intrafamily distribution rule i e wants out of consumption data

growth and saving among individuals and households the lifecycle theory of saving and consumption predicts that changes in an economy s rate of economic growth will affect its aggregate saving rate by changing the lifetime resources of younger people relative to older people however studies that track the saving behavior of cohorts of household heads over time as they age have yielded estimates of age saving profiles that are too flat for growth to have much effect on the aggregate saving rate one problem with the cohort approach is that multigenerational households are common in many counties and the age saving profiles of households may be quite different from the age saving profiles of individuals that make up households in this paper we propose a method for estimating individual age saving profiles using household data this method is applied to data from taiwan and thailand we find that the individual method yields results that are more favorable to the lifecycle model these results imply that changes in the rate of economic growth may in som

a survey measure of risk aversion abstract we use survey data on the well being of individuals to measure attitudes toward risk risk neutrality cannot be rejected by the data

saving taxes through foreign plant ownership this paper analyzes to which extent foreign plant ownership involves lower tax payments than domestic plant ownership we employ a model of endogenous foreign subsidiary ownership to derive a set of empirically testable hypotheses about the differential taxation of foreign and domestically owned subsidiaries we assess these hypotheses in a data set of 33 577 european foreign and domestically owned manufacturing plants we identify a significant tax saving of endogenous foreign owner ship on average foreign owners pay 594 euros per employee or about 56 percent less than domestic owners of similar subsidiaries this effect is larger in thinner markets with fewer plants in markets with a greater relative presence of foreign owners and for foreign owners of larger plants

social security and old age unemployment risk with efficient wage bargaining i analyze a life cycle economy with old age productivity risk where wages employment and severance payments are set through efficient bargaining between risk averse unions and risk neutral firms allocations with limited union membership are second best inefficient as they generate too little labor supply in young age too much consumption before retirement too little employment of older workers early retirement and too little insurance against old age unemployment providing public transfers to early retirees disability benefits or early pensions might help to increase the degree of risk sharing at the cost of lower old age employment depending on whether absolute risk aversion is increasing or decreasing in consumption these policies might or might not produce efficiency gains at equilibrium

demographics and the natural interest rate in the euro area abstract we investigate the impact of demographics on the natural rate of interest nri in the euro area with a particular focus on the role played by economic openness migrations and pension system design to this end we construct a life cycle model and calibrate it to match the life cycle profiles from hfcs data we show that population aging contributes significantly to the decline in the nri explaining about two thirds of its secular decline between 1985 and 2030 openness to international capital flows has not been important in driving the ea real interest rate as aging in europe has been similar to that in the rest of the world so far of two possible pension reforms only an increase in the retirement age can revert the downward trend on the equilibrium interest rate while a fall in the replacement rate would make the decline in nri even deeper the demographic pressure on the eurozone nri can be alleviated by increased immigration but only to a small extent and with a substantial lag

taxation and the user cost of capital this paper provides a review of the concept of user cost and its determinants particular attention is given to the influence of taxation the concept of user cost relates to the rental the rate of return to capital that arises in a profit maximizing situation in which further investment in capital produces no additional profit this paper sets out in some detail the range of assumptions involved in obtaining alternative expressions for the user cost the user cost refers to a before tax capital rental the rate of return that ensures that the after tax cost of capital is equal to the post tax returns over its life hence associated with the user cost measure is an effective marginal tax rate this can differ substantially from the statutory marginal rate applicable to the investor a related effective average tax rate is also defined

consumption over the life cycle facts from consumer expenditure survey data this paper uses consumer expenditure survey data and a seminonparametric statistical model to estimate life cycle profiles of consumption controlling for demographics cohort and time effects we construct age profiles for total and nondurable consumption as well as expenditure patterns for consumer durables special emphasis is placed on the comparison of different approaches to control for changes in demo graphics over the life cycle we find significant humps over the life cycle for total nondurable and durable expenditures changes in household size account for roughly half of these humps bootstrap simulations suggest that our empirical estimates are tight in that standard errors are small

swedish tax rates labor supply and tax revenues effective marginal tax rates on labor income for the representative swede have increased from roughly 50 percent in 1959 to 80 percent today the effects of this increase in the level of taxation are examined using a two sector model parameterized to correspond to the swedish economy the model contains a single household which allocates labor to either taxed essentially market or untaxed largely household uses the estimated long run effects are sufficient to explain up to 75 percent of the recent decline in the measured growth rate of the swedish gnp calculations of total tax revenues are also derived from the model these peak when the tax rate is approximately 70 percent indicating that sweden is presently on the downward sloping portion of its laffer curve

the definition and measurement of poverty both poverty research and social policy employ a variety of poverty definitions the choice of one specific definition has major consequences for the resulting poverty population this paper uses eight different definitions of poverty to determine who is poor using a 1983 dutch sample of more than 12 000 households poverty according to each of these definitions is compared over different subgroups the relevance of the choice between definitions for social policy is shown by the presentation of poverty percentages according to the various definitions which vary widely

full insurance in the presence of aggregate uncertainty this paper tests implications of full consumption insurance the object is to determine how much mileage can be obtained from a model with complete markets with such features as private information or liquidity constraints omitted the implication exploited is that individual consumption responds to aggregate risk but not to idiosyncratic risk the test involves regressing the change in household consumption onto the change in aggregate consumption and other right hand side variables such as the change in household income and change in employment status all variables other than the change in aggregate consumption are predicted to be insignificant in explaining the change in household consumption with observations on consumption and income for 10 695 households from the consumer expenditure survey the results are mixed the results for one specification exponential utility are mostly consistent with full consumption insurance the results for the other specification power utility are not

why has house price dispersion gone up we calibrate a dynamic general equilibrium island model to investigate the 30 year increase in the level of house prices and their dispersion across u s metropolitan areas the model is based on two main assumptions households o w in and out metropolitan areas in response to local productivity shocks and the housing supply cannot adjust instantly because of technological and regulatory constraints the calibration reveals that the observed tightening of housing supply regulation cannot quantitatively account for the rise in the level and dispersion of house prices in equilibrium workers o w out of tightly regulated towards less regulated metropolitan areas undoing most of the price impact of local supply restrictions in contrast the observed increase in wage dispersion across metropolitan areas does create the observed increase in the level and dispersion of house prices workers o w towards exceptionally productive metropolitan areas and drive house prices up the calibration also suggests that the welfare eects of housing supply regulation are large when wages become more dispersed

homogeneous profit tax effects for heterogeneous firms in most countries profit taxation is probably much more relevant nowadays than trade liberalisation when it comes to firm level decisions about investment empirically firms are quite heterogeneous with regard to fixed costs the composition of assets tangible versus intangible machinery versus buildings etc and the financing of investments then even uniform changes in profit tax instruments cause heterogeneous responses of firm level effective tax rates and hence after tax profits we argue that with similar profit margins firms would then require pre tax profits to differ as well governments change statutory profit tax rates and by virtue of firms heterogeneity they cause stark selection effects which are mainly related to heterogeneous fixed rather than variable costs we compute costs of capital for a large sample of firms to illustrate how homogeneous changes in tax instruments hit firms differently using bureau van dijk s orbis database we illustrate that the effects of changes in statutory instruments have relatively large systematic variance components across industries within countries and also relatively large ones of firms within industries and countries

accounting for the gender gap in college attainment i introduction one striking phenomenon in the u s labor market is the reversal of the gender gap in college attainment in 1980 57 of young men aged 25 34 compared with 46 of young women had some college education by age 34 by 1996 however female college attainment had reached 64 5 percentage points higher than that of the males in the same cohort in tact females overtook males in college attainment in 1987 and have led ever since a large body of empirical research emphasizes the role of the earnings premium as a key explanatory variable for the determination of education outcomes see e g becket 1967 mincer 1974 willis and rosen 1979 in addition an extensive literature shows that family background is an important determinant of the schooling decision see among others cameron and heckman 1998 2001 eckstein and wolpin 1999 ge 2008 kane 1994 recently several papers have argued empirically and theoretically that expected marriage is important in determining the schooling decision e g chiappori iyigun and weiss 2006 ge 2008 iyigun and walsh 2007 on the basis of this literature we construct a life cycle model that includes potential costs and benefits from the labor market and marriage market which determine individual college decisions in our model individuals with differing learning abilities first decide whether or not to enter college then they might get married and have children parents are altruistic and value their children s learning ability which increases with the parents education forward looking individuals take into account the impact of their own schooling on their children s learning ability other factors that affect an individual s decision on whether to pursue higher education include the expected direct labor market returns to college over one s lifetime the expected marriage market returns to college and the financial and effort costs of attending college these costs and benefits can differ by gender we calculate from panel study of income dynamics psid and current population survey cps parents education distributions the life cycle profiles of single marriage and divorce probabilities by education and the lifecycle profiles of earnings by education and marital status as exogenous inputs of the model we observe that the number of college educated parents increases over time in the marriage market a substantial increase of single probabilities and an increase of divorce probabilities has occurred for both genders regardless of college attainment status lifetime earnings by cohort are decreasing slowly for males of all marital statuses especially for married males lifetime earnings for married and divorced females are increasing gradually whereas those for single females are decreasing slightly to formally endogenize those changes is beyond the scope of our paper we instead focus on the mechanism in which under perfect foresight these changes affect education decisions we estimate the parameters of the model by matching data on college attainment by gender from the psid we present evidence on how well the model fits the data we then use the parameter estimates to simulate counterfactual experiments which break down the sources of changes in college attainment into the effects of changes in relative earnings changes in parental education and changes in the marriage market what accounts for the increase in college attainment over the past few decades we find that the increasing gap in earnings between college and high school graduates has important effects on the increase in college attainment for both genders when earnings are fixed at 1946 cohort levels attainment rates in 1996 drop by 15 5 and 14 2 percentage points for males and females respectively we also emphasize the importance of intergenerational persistence in schooling on the increase in college attainment for both genders

poverty and the measurement of individual welfare a review article this review of hagenaars the perception of poverty gives a lengthy presentation and evaluation of the leyden approach of measuring the individual welfare function of income the key feature of the approach is the claim that welfare can be measured on a 0 1 scale the review discusses the book s wealth of material on poverty in europe within this theoretical framework

household economies of scale in consumption theory and evidence household economies of scale arising from the existence of househo ld public goods increasing returns in household production and or bulk discounts are incorporated into a utility theoretic model of household demands individuals are assumed to be identical and symmetrically treated within households economies of scale parameters for five goods are estimated using the quadratic expenditu re system and data from the u s consumer expenditure survey on expenditures by all adult households results suggest the existence o f significant economies of scale in the consumption of all of the included goods with economies being especially pronounced in the consumption of shelter copyright 1988 by the econometric society

a cohort analysis of saving behavior by u s households the aim of this paper is to shed some light in the decline in personal saving rates in the united states in the 1980s for a such a purpose the paper analyses the only u s data set containing information on consumption and income at the household level the consumer expenditure surveys cex from 1980 to 1991 because the cex is not a panel most of the analysis is conducted using average cohort techniques the paper identifies a typical age profile for saving rates such a profile is hump shaped and peaks around age 57 the paper also argues that such a profile was shifted down for the cohorts born between 1920 and 1939 relative to the younger and older cohorts considered these cohorts are the parents of the baby boom generation the paper also argues that these cohort effects can account for a non neglible proportion of the decline in aggregate saving because these cohorts were during the 1980s in the ages when saving rates are typically highest the result is robust to the consideration of several controls and holds for several definitions of consumption the only exception is when durable expenditure is considered as saving rather than consumption

unemployment in the great recession this paper studies the responses of unemployment in germany the united states and britain to the great recession of 2008 09 by making use of beveridge curve analysis and in the entire oecd with other techniques it is shown that britain suffered from recession but no structural problems the united states suffered from structural unemployment during the recovery germany exhibited a much better performance both during and after the recession the rise in oecd unemployment is broken down into parts due to aggregate activity the construction sector and a residual attributed to policies and institutions which is used to reach conclusions about policy

empirical evidence on the trade impact of asynchronous regulatory approval of new gmo events abstract this paper focuses on the ex post empirical analysis of the trade impact of asynchronous regulatory approval of new genetically modified organism gmo events we contribute to the literature in three ways first we define indices to assess the extent of asynchronicity and the relative strictness of the gmo approval authorizations of 40 countries considering gmo regulatory developments between 2000 and 2012 regarding cotton maize and soybeans second we introduce indices that are country pair specific product specific and year specific in a gravity model to examine the trade impact of asynchronous regulatory approval across countries by grouping the countries according to the state of their national regulatory gmo frameworks we have an even more differentiated view on the trade impact of asynchronous approval that focuses not only on the existence of regulations but also on their restrictiveness the results from the gravity model show that asynchronous approval has negatively impacted trade flows of cotton maize and soybeans it is observed that both asynchronous approvals and the restrictiveness of importing countries regulations to address the importation of gmo products matter meaning those countries that have already adopted a comprehensive gmo regulatory framework and have policies to manage the importation of gmo crops tend to feel a higher negative impact on trade flows

adjustment of consumers durables stocks evidence from automobile purchases this paper tests an optimal s s rule in household durable purchases and examines directly the resulting aggregate expenditure dynamics the observed decision rule responds to income uncertainty and growth as predicted by an s s model resulting from transactions costs tests against liquidity constraints find that about half the households purchase according to an optimal s s rule aggregating the s s rule over households produces a cross section distribution of durables holdings the empirical distribution is similar to that predicted theoretically as is its response to aggregate shocks furthermore simulations of aggregate expenditure based on the household distribution exhibit dynamics consistent with those observed in the 1980s

the trade off between equality and efficiency this paper uses a 1976 microdata base to estimate the marginal cost of reducing income inequality with a policy that has distributional effects similar to the present tax transfer system the analysis uses a simulation methodology in which only the labor supply effects are evaluated other behavioral effects are ignored the most striking finding is that marginal cost is quite high even for modest labor supply elasticities for example in the benchmark case with a weighted average economy wide uncompensated wage elasticity of 0 2 and compensated elasticity of 0 31 the disposable money income of upper income quintiles of households is depressed by 9 51 for each dollar increase in the disposable money income of lower income quintiles when income equivalent values that take account of the value of leisure are compared the marginal cost for this case is estimated to be 3 49

efficiency gaps love of variety and international trade we develop a general equilibrium monopolistic competition model of trade with technical heterogeneity among firms and countries with free entry technical asymmetries between firms result in the endogenous determination of the equilibrium average efficiency of the industry we show that trade reduces increases the minimum efficiency required to survive in the more less efficient country this has important welfare implications 1 contrary to the constant elasticity of substitution homogeneous firms model trade affects welfare even when there is no love of variety 2 there are circumstances in which trade liberalization leads to a loss of consumer welfare

aggregate consumer behavior and household equivalence scales this article presents estimates of household equivalence scales broken down by demographic characteristics of u s households separate estimates are given by family size age of head region race and urban versus rural residence commodity specific scales are presented for five separate commodity groups energy food consumer goods capital services and other services the estimates are obtained from an econometric model of aggregate consumer behavior the parameters of this model are estimated by combining aggregate time series and individual cross section data

consumption over the life cycle and over the business cycle the main aim of this paper is to assess the validity of the life cycle model of consumption in particular we address an issue that has recently received much attention especially in the macroeconomic literature that of excess sensitivity of consumption growth to income growth we do this using a time series of cross sections and a novel and flexible parameterization of preferences the former allows us to address aggregation issues directly while with the latter we can allow both the discount factor and the elasticity of intertemporal substitution eis to be affected by various observable variables and lifetime wealth the main findings can be summarized as follows i the excess sensitivity of consumption growth to labor income disappears when we control for demographic variables this is true both at life cycle and business cycle frequencies ii estimation of a flexible specification of preferences indicates that the elasticity of intertemporal substitution is a function of several variables including the level of consumption the eis increases with the level of consumption as expected iii the variables that change the eis are also important in explaining why we observe excess sensitivity over the business cycle iv we are able to reconcile our results with those reported both in the macro and micro literature v in our specification the elasticity of intertemporal substitution is not very well determined this result however should be taken with care as we have not made an effort to construct a preferred specification which would probably include additional controls for labor supply behavior the evidence presented shows that the life cycle model cannot be easily dismissed indeed we believe that the model does a good job at representing consumption behavior both over the life cycle and over the business cycle
