cheap children and the persistence of poverty this paper develops a theory of fertility that offers an explanation for the persistence of poverty within and across countries if educated individuals have a comparative advantage in raising educated children then parental fertility choice is shown to give rise to a poverty trap in which the poor choose high fertility rates with low investment in child quality moreover the impact of child quality choice on economic performance is amplified by the diluting effect of higher fertility on physical capital accumulation the theory proposes insights regarding the effects of inequality globalisation and life expectancy on economic growth and demographic transitions this paper develops a theory of fertility and child educational choice that offers an explanation for the persistence of poverty within and across countries the joint determination of the quality education and quantity of children in a household is studied under the key assumption that individuals productivity as teachers increases with their own human capital in contrast the minimum time cost associated with raising a child regardless of the child s quality the quantity cost is not affected by parental education as a result the price of child quantity relative to the price of child quality increases with individuals wages in particular for low wage individuals for whom the opportunity cost of time is low children of minimal quality are cheap this assumption therefore generates a comparative advantage for the poor in child quantity whereas high wage educated individuals have a comparative advantage in raising quality children consistent with the well known evidence poor households thus choose relatively high fertility rates with relatively low investment in their offspring s education and therefore their offspring are poor as well in contrast high income families choose low fertility rates with high investment in education and therefore high income persists in the dynasty evidence from the us provided by hanushek 1992 suggests that a trade off between quantity and quality of children does indeed exist hanushek argues that movements in family size could explain over half the variance in some test scores and that the elasticity of achievements with respect to the number of children in the family is 0 03 implying that the annual achievement growth of each child in a family will fall about 2 when a second child is added and about 0 5 when a sixth child is added 1

money market integration we use transaction level data and detailed modeling of the high frequency behavior of federal funds eurodollar spreads to provide evidence of strong integration of the u s markets for federal funds and eurodollars the two core components of the dollar money market our evidence of negligible federal funds eurodollar premia contrasts with previous findings of large and predictable premia which have been interpreted as evidence of segmentation between the markets for federal funds and eurodollars our results however are consistent with possible persistent segmentation within the global eurodollar market we document several patterns in the behavior of federal funds eurodollar spreads including liquidity effects from trading volume to yield spreads volatility

gender domestic labor time and wage inequality this paper explores the relationship between domestic labor and wage labor by estimating the relative influence of hours spent in domestic labor e g housework and child care on women s and men s wages it is hypothesized that involvement in domestic activities negatively affects wages and is likely to be an important factor in explaining women s lower wages relative to men findings from ols regression analyses of white currently employed currently married women and men indicate that domestic labor time significantly decreases both sexes wages in order to assess whether this relationship differs by class the sex specific earnings equations also are estimated within the working class and the non working class the negative effect of domestic labor time on both sexes income persists in the within class analyses working class men are more vulnerable to the detrimental influence of domestic production unexpectedly housework and child care time decreases non workingclass women s wages more so than working class women s wages it is noted that these findings should be interpreted with caution due to the cross sectional nature of the data which precludes an unequivocal assessment of potential nonrecursivity in the linkages among key variables in the model overall the findings imply that a more equitable distribution of work in the home is necessary before labor market inequalities between the sexes can be ameliorated

intelligence social mobility and growth this study develops a model where the allocation of human resources intergenerational social mobility and technological growth are jointly determined high growth endogenously increases the equilibrium return to innate cognitive ability and makes the allocation of individuals depend more on innate ability and less on social background a social allocation based on innate ability and high growth will thus reinforce each other implying the possibility of multiple endogenous growth equilibria

changes in the u s wage structure 1963 1987 application of quantile regression the 1980 s witnessed rapid changes in the structure of wages in the united states in this study recently developed techniques for quantile regression are applied to every march current population survey since 1964 and changes in the return to schooling and experience at different points of the wage distribution are examined the quantile regression technique parsimoniously describes the entire conditional wage distribution this conditional distribution is used to examine changes in within group wage inequality as measured by the difference between conditional quantiles two linear models are considered a simple one group model and a 16 group model the results suggest that the returns to schooling and experience differ across quantiles of the wage distribution but their patterns of change are similar significant differences in wage inequality are also found across the various skill groups the paper also presents a new imputation method for cps data

winners and losers in russia s economic transition the transition to a market economy has produced a substantial and rapid change in the wage structure in russia household surveys taken before and after the transition indicate that overall wage inequality nearly doubled from 1991 to 1994 and has reached a level higher than that in the united states returns to both measured skills education occupation and unmeasured skills within groups have increased considerably skill premiums across experience groups however have become more compressed and relative wages of older workers have declined in addition female wages have declined relative to male wages across all percentiles of the wage distribution copyright 1998 by american economic association

income distribution and macroeconomics this paper analyzes the role of wealth distribution in macroeconomics through investment in human capital it is shown that in the presence of credit markets imperfections and indivisibilities in investment in human capital the initial distribution of wealth affects aggregate output and investment both in the short and in the long run as there are multiple steady states this paper therefore provides an additional explanation for the persistent differences in per capita output across countries furthermore the paper shows that cross country differences in macroeconomic adjustment to aggregate shocks can be attributed among other factors to differences in wealth and income distribution across countries

what has 20 years of public private pay gap literature told us eastern european transitioning vs developed economies this paper surveys the literature on public private sector pay differentials based on 20 years of research in transitioning countries of eastern europe ee and compares the results with estimates obtained from developed market economies the majority of empirical studies from ee economies found evidence of public sector pay penalties during the period of economic transition from a communist to market based economy in developed economies however the average differential is usually around zero or positive the public sector pay inequality reducing effect relative to the private sector is greater in transitioning economies than in developed economies nevertheless there is evidence that the sign of the public sector pay gap as well as the relative public sector pay distribution change with the progress of economic transition towards those usually observed in developed economies different pay setting arrangements between private and public sectors and competition for workers seem to be major arguments for the existence of systematic pay differences between the two sectors

credit derivatives premium as a new japan premium at the height of the japanese banking crisis of 199798 a popular indicator of weakness was the so called japan premium that is the premium in the interest rate charged to japanese banks in the interbank market the internationally active japanese banks had to pay a premium in borrowing us dollars and to a much lesser extent japanese yen from western banks the japan premium was considered to reflect western banks skepticism on opaque accounting and supervision ihe japan premium disappeared after the second capital injection to major banks in march 1999 l by the end of 2001 the vulnerability of japanese banks became obvious due to low earnings newly emerged nonperforming loans and deflation the core capital tier i capital was depleted and was supplemented only by deferred tax credit which has no liquidation value however it was noted by banking experts and researchers that the japan premium did not reappear it was a puzzle why the premium was not demanded this time the focus of this letter is to explain why the japan premium apparently disappeared and to report on an alternative indicator for japanese bank vulnerability that would replace the japan premium we will assert that the japan premium the

public schooling college subsidies and growth abstract how does the mix of public education expenditures across primary and secondary k 12 education and post secondary college education influence economic growth to address this i build an overlapping generations endogenous growth model human capital is accumulated through compulsory k 12 education and through optional college education government uses tax revenue to provide quality in k 12 schooling and to subsidize college tuition when total expenditures are small all funds should provide k 12 quality when expenditures are above a critical value a positive share should subsidize tuition the share should increase with total expenditures and with the degree of complementarity of human capital accumulated through the two types of education also increased education spending is more likely to increase growth when a larger share subsidizes tuition

winners and losers in transition returns to education experience and gender in slovenia the authors identify winners and losers in slovenia s economic transition by tracing changes in returns to education experience and gender and changes in wage inequality from 1987 to 1991 they find the following relative wages and employment rose for the most educated and fell for the least educated in all industries relative wages and employment rose with years of work experience until pensionable age at pensionable age relative wages increased very rapidly and relative employment was greatly reduced using pension policies to encourage early retirement drastically reduced the supply of very experienced workers either the policy caused firms to bid up wages for workers of pensionable age to keep them from retiring or it caused a selection process in which only the highest paid workers remained in the workforce regardless the pension policy has proved to be costly and early retirements did not make room for the youngest workers but for those just under pensionable age women gained relative to men in both wages and employment primarily because they occupy education and industry groups less adversely affected by the transition not because of economywide reductions in discrimination against women increasing returns to education and experience contributed to wage inequality but the variance in wages also increased for individuals with identical skills big changes in relative wages should signal future reallocation of labor toward more productive higher paying sectors setting minimum wages fixing ranges of pay and indexing wages to inflation did not prevent increases in wage variation from occuring wage minimums did not appear to have an effect presumably because inflation reduced real minimum wages so quickly that most workers were paid above the minimums in slovenia policy changes are reflected in labor market outcomes disabling the tax transfer policy from relatively profitable to relatively unprofitable firms and eliminating worker referendums on wage scales removed mechanisms that tended to compress wage variation greater demand for skilled workers also reflected both the economywide need to cope with uncertainty and such industry specific factors as reduced labor demand especially in less skill intensive industries the results in slovenia contrast sharply with those in eastern germany eastern german workers have had decreasing returns to education and experience but it is not clear how relevant the eastern german experience is to other transitional economies because of western germany s efforts to alleviate problems more similar to the authors findings are the results of flanagan 1993 on the czech republic which show increasing returns to education but decreasing returns to experience in some respects slovenia is atypical because it is richer and more western in orientation than other transitional economies however economies could learn from the experience in slovenia because slovenia also had social ownership full employment coupled with substantial hidden unemployment and an egalitarian wage structure and slovenia has introduced labor market reform and experienced social dislocations similar to those in other transitional european economies

market specific and currency specific risk during the global financial crisis evidence from the interbank markets in tokyo and london abstract this paper investigates how international money markets reflected credit and liquidity risk during the global financial crisis after matching the currency denomination we examine how the tokyo interbank offered rate tibor was synchronized with the london interbank offered rate libor we find remarkably asymmetric responses in market specific and currency specific risk during the crisis the regression results suggest that market specific credit risk increased the difference across markets whereas liquidity risk caused the difference across currency denominations they also support the view that liquidity shortage of the us dollar occurred in international money markets during the crisis coordinated central bank liquidity provisions were useful in reducing the liquidity shortage of the us dollar but their effectiveness was asymmetric across markets

changes in the structure of earnings during the polish transition abstract we document changes in the structure of earnings during the economic transition in poland we find that inequality in labor earnings increased substantially from 1988 to 1996 a common view is that the reallocation of workers from a public sector with a compressed wage distribution to a private sector with much higher wage inequality accounts for the bulk of increased earnings inequality during transition see e g the models of aghion and commander 1999 aghion philippe commander simon 1999 on the dynamics of inequality in the transition economics of transition 7 275 2898 and commander and tolstopiatenko 1998 commander simon tolstopiatenko andrei 1998 the role of unemployment and restructuring in the transition in commander simon ed enterprise restructuring and unemployment in models of transition the world bank washington pp 169 192 however our decomposition of the sources of the increase in inequality suggests that this compositional effect accounts for only 39 of the increase fully 52 of the increase is due to the increase in the variance of wages within sectors that is earnings inequality within both the private and public sectors grew substantially and by similar amounts this is consistent with prior work suggesting that even state owned enterprises in poland moved towards competitive wage setting as they restructured see e g pinto et al 1993 pinto brian belka marek krajewski stefan 1993 transforming state enterprises in poland evidence on adjustment by manufacturing firms brookings papers on economic activity 213 70 commander and dhar 1998 commander simon dhar sumana 1998 enterprises in the polish transition in simon commander ed enterprise restructuring and unemployment in models of transition the world bank washington pp 109 142 a substantial part of the increase in earnings inequality was between group due largely to increased education premiums however changes in inequality within education experience gender groups account for about 60 percent of the increase in overall earnings inequality the increases in within group inequality were very different across skill groups with much larger increases for highly educated workers these patterns hold in both the private and public sectors although increases in education premiums were somewhat greater in the private sector

maids appliances and couples housework the demand for inputs to domestic production maids household appliances and housework time are key inputs to domestic production this study uses data from the uk and france to estimate the effects of resource prices on the demand for these inputs we conclude that higher opportunity costs of time increase the likelihood of having maid services and appliances women s time costs are also positively related to his housework time and negatively related to hers finally maid service appears to be a closer substitute for housework time on weekend days than weekdays suggesting smaller labour supply effects than anticipated by earlier literature abstract from author

employment schedules among dual earner spouses and the division of household labor by gender i extend the research on how employment schedules affect family life and which factors determine a husband s share in household labor i present a new specification of the concept of available time among dual earner couples the amount of overlap in hours in spouses employment schedules and whether a spouse works day evening night or rotating shifts i show that variations in employment schedules are significant determinants of a husband s share in traditionally female household tasks also important are certain aspects of spouses resources gender role ideology and stage in the life course interpretations of these findings take into account whether it is the husband s and or wife s hours performing household tasks that are affected by these variables since husband s share depends on both the data come from the 1986 1987 national survey of families and households and my findings support the view that modest increases in husbands participation in household labor may result from the growing diversity in employment schedules among american workers

interbank interest rates funding liquidity risk and xibor basis spreads abstract this article presents a theoretical model for interbank money market xibor rates that endogenously generates the basis spreads that characterize post crisis fixed income markets xibor ois spreads tenor basis spreads and the forward basis our approach is based on an explicit modeling of interbank cash transactions where interbank credit and liquidity risk are factored in the framework of this article offers a consistent arbitrage free explanation for the emergence of basis spreads we also demonstrate that funding liquidity is a key determinant of post crisis xibor rates and in particular tenor basis spreads

the state courts and maternity policies in u s organizations specifying institutional mechanisms we analyze the dynamic interaction of state institutions and organizational policies through an analysis of leave benefits in u s organizations following the pregnancy leave act of 1978 and the family and medical leave act of 1993 organizations have been required by law to allow workers to take time off from work for childbearing and childrearing yet organizations vary on whether they offer full time employees benefits that actually facilitate leave for family responsibilities we analyze the determinants of the organizational decision to offer paid maternity leave to full time employees we compare these findings to the determinants of the organizational decision to offer paid sick leave to full time employees our analysis suggests that organizations have taken an activist approach to their institutional environments in the face of federal definitions of the law that mandated gender neutral policies in the workplace and linked pregnancy to disability those organizations that most often deal with maternity issues e g those located in female dominated industries have institutionalized sick leave policies often instead ofmaternity leave to accommodate pregnant employees the analysis examines specific aspects of the institutional environment at the state and federal levels to illuminate these trends

ability biased technological transition wage inequality and economic growth thispaper develops a growthmodel characterizedbyability biasedtechnological transition in which the evolution of technology education attainment and wage inequality is consistent with the observed pattern in the united states and other advanced countries over the past several decades it argues that an increase in the rate of technological progress raises the return to ability and simultaneously generates an increase in wage inequality between and within groups of skilled and unskilled workers an increase in average wages of skilled workers a temporary decline in average wages of unskilled workers an increase in education and a productivity transitory slowdown

decomposing the labor market earnings inequality the public and private sectors in vietnam 1993 2006 in contrast with the typical transition to a market economy earnings inequality in vietnam between 1993 and 2006 appears to have decreased and the earnings gap in favor of public employees appears to have widened we use a comparative advantage model to disentangle the effect of sorting workers across sectors from the effect of the differences in returns to workers skills the selection of the best workers into the public sector is clearly an important component of the explanation for the public private sector earnings gap but the widening of this gap over time is primarily due to changes in the compensation patterns we find that in the 1990 s public employees were underpaid compared with their earning potential in the private sector whereas in the early 2000s public employees earned similar returns to their comparative advantage in the public and private sectors the increasing homogeneity in returns to skills in the vietnamese labor market appears to explain both the increase in the public private pay gap and the decrease in overall inequality

threshold arch models and asymmetries in volatility this paper attempts to enlarge the class of threshold heteroscedastic models tarch introduced by zakoian 1991a we show that it is possible to relax the positivity constraints on the parameters of the conditional variance unconstrained models provide a greater generality of the paths allowing for nonlinearities in the volatility cyclical behaviour is permitted as well as different relative impacts of positive and negative shocks on volatility depending on their size we give empirical evidence using french stock returns

firm heterogeneity in capital labour ratios and wage inequality author s leonardi marco abstract this paper documents the increasing dispersion of capital labor ratios across firms in the us and provides some empirical evidence of a positive correlation at the two digit industry level between the dispersion of capital labor ratios across firms and residual wage inequality to explain this empirical fact the paper adopts a search model where firms differ in their optimal capital investment the exogenous decline in the relative price of equipment capital makes the distributions of capital labor ratios more dispersed in a frictional labor market this force generates wage dispersion among identical workers ols estimates of the relationship between capital dispersion and the relative price of equipment capital support the main hypothesis of the model

from turmoil to crisis dislocations in the fx swap market before and after the failure of lehman brothers abstract this paper investigates dislocations in the foreign exchange fx swap market between the us dollar and three major european currencies after the failure of lehman brothers in september 2008 deviations from covered interest parity cip were negatively associated with the creditworthiness of us financial institutions as well as that of european institutions consistent with the deepening of a dollar liquidity problem into a global phenomenon us dollar term funding auctions by the ecb snb and boe as well as the us federal reserve commitment to provide unlimited dollar swap lines are found to have ameliorated the fx swap market dislocations

a yen is not a yen tibor libor and the determinants of the japan premium pricing in the euroyen market is based on libor the london interbank offered rate set at 11 00am london time or tibor the tokyo interbank offered rate set at 11 00am tokyo time the changing tibor libor spread reflects the credit risk associated with japanese banks or the japan premium the spread is modeled as a function of determinants of bank default and firm value systematic variation in the spread can be explained by interest rate and stock price effects along with public information flows of good and bad news regarding japanese banking with a separate role for bank credit downgrades and upgrades

technological acceleration skill transferability and the rise in residual inequality this paper provides a quantitative theory for the recent rise in residual wage inequality consistent with the empirical observation that a sizable part of this increase has a transitory nature a feature that eludes standard models based on ex ante heterogeneity in ability an acceleration in the rate of quality improvement of equipment like the one observed from the early 1970s increases the productivity quality differentials across machines jobs in a frictional labor market this force translates into higher wage dispersion even among ex ante equal workers with vintage human capital the acceleration reduces workers capacity to transfer skills from old to new machines generating a rise in the cross sectional variance of skills and therefore of wages through calibration the paper shows that this mechanism can account for 30 percent of the surge in residual inequality in the u s economy or for most of its transitory component two key implications of the theory faster within job wage growth and larger wage losses upon displacement find empirical support in the data

the transition in east germany when is a ten point fall in the gender wage gap bad news the gender wage gap in east germany has narrowed by 10 percentage points in transition but women have experienced much more severe employment difficulties than men using the german socio economic panel for 1990 94 i show that on balance women have lost relative to men almost half the relative wage gain is due to exits from employment of the low skilled who are disproportionately women the female employment decline is not primarily voluntary more than half the gender gap in the hazard rate from employment reflects a general fall in demand for low skilled workers reduced child care plays no role

the employment and wage effects of oil price changes a sectoral analysis in this paper we use micro panel data to examine the effects of oil price changes on employment and real wages at the aggregate and industry levels we also measure differences in the employment and wage responses for workers differentiated on the basis of skill level we find that oil price increases result in a substantial decline in real wages for all workers but raise the relative wage of skilled workers the use of panel data econometric techniques to control for unobserved heterogeneity is essential to uncover this result which is completely hidden in ols estimates while the short run effect of an oil price increase on aggregate employment is negative the long run effect is in fact positive we find that changes in oil prices induce changes in employment shares and relative wages across industries however we find little evidence that oil price changes cause labor to consistently flow into those sectors with relative wage increases copyright 1996 by mit press

determinants of the japan premium actions speak louder than words abstract since august 1995 japanese banks have had to pay a premium on eurodollar and euroyen interbank loans relative to their u s and u k competitors this so called japan premium provides a market indicator of investor anxiety about the ability of japanese banks to repay loans we examine the determinants of the japan premium and find that government announcements not associated with concrete actions had little impact on the other hand announcements of concrete actions by the japanese government such as injections of funds into the banking system tended to have an effect on the size of the japan premium

monetary policy and covered interest parity in the post gfc period evidence from the australian dollar and the nz dollar abstract after the global financial crisis gfc most major currencies had higher interest rates than the us dollar on forward contract because of increased demand for the us dollar as international liquidity however unlike the other major currencies the australian dollar and the nz dollar had lower interest rates than the us dollar on forward contract in the post gfc period the purpose of this paper is to explore why this happened through estimating the covered interest parity cip condition in the analysis we focus on a unique feature of australia and new zealand where short term interest rates remained significantly positive even after the gfc the paper first constructs a theoretical model where increased liquidity risk causes deviations from the cip condition it then tests this theoretical implication by using daily data of six major currencies we find that both money market risk measures and policy rates had significant effects on the cip deviations the result implies that unique monetary policy feature in australia and new zealand made deviations from the cip condition distinct on the forward contract

the diffusion of computers and the distribution of wages abstract when the costs are decreasing workers adopt technology at the point where the costs equal the increased productivity output per worker increases immediately while productivity benefits increase only gradually if costs continue to fall as a result workers in computer adopting labor market groups experience an immediate fall in wages due to increased supply on the other hand adopting workers experience wage increases with some delay this model explains why increased computer use does not immediately lead to higher wage inequality more specifically the results of the model are shown to be consistent with the question why within group wage inequality among skilled workers as a result of computer technology adoption in the united states increased in the 1970s while between group wage inequality and within group wage inequality among the unskilled did not start to increase until the 1980s the model also predicts that the more compressed german wage structure leads to a lagged diffusion of computer technology along with smaller changes in wage inequality our empirical analysis suggests that this is consistent with the actual developments in germany since the 1980s finally the theoretical predictions seem to be of the right magnitude to explain the empirical quantities observed in the data

college entry by blacks since 1970 the role of college costs family background and the returns to education college enrollment of black 18 19 year old high school graduates declined from 1980 through 1984 and then rebounded after 1984 this paper presents data from a time series of cross sections of 18 19 year old youths from 1973 through 1988 to test the role of family background direct college costs local economic conditions and returns to college in driving these trends the evidence suggests that on the one hand increases in direct college costs were driving enrollment rates downward throughout the eighties on the other hand dramatic increases in average parental education for black youths exerted upward pressure on college enrollment by blacks particularly in the latter half of the decade the net effect of these two factors contributed to the pattern of decline and recovery observed during the eighties

government spending composition technical change and wage inequality in this paper we argue that government spending played a significant role in stimulating the wave of innovation that hit the u s economy in the late 1970s and in the 1980s as well as the simultaneous increase in inequality and in education attainments since the late 1970s u s policymakers began targeting commercial innovations more directly and explicitly we focus on the shift in the composition of public demand toward high tech goods which by increasing the market size of innovative firms functions as a de facto innovation policy tool we build a quality ladders non scale growth model with heterogeneous industries and endogenous supply of skills and show that an increase in the technological content of public spending stimulates r d raises the wage of skilled workers and at the same time stimulates human capital accumulation a calibrated version of the model suggests that government policy explains between 12 and 15 of the observed increase in wage inequality in the period 1976 1991 jel e62 j31 o33 o41
