systemic risk contributions a credit portfolio approach we put forward a merton type multi factor portfolio model for assessing banks contributions to systemic risk this model accounts for the major drivers of banks systemic relevance size default risk and correlation of banks assets as a proxy for interconnectedness we measure systemic risk in terms of the portfolio expected shortfall es banks marginal risk contributions are calculated based on partial derivatives of the es in order to ensure a full risk allocation among institutions we compare the performance of an importance sampling algorithm with a fast analytical approximation of the es and the marginal risk contributions furthermore we show empirically for a portfolio of large international banks how our approach could be implemented to compute bank specic capital surcharges for systemic risk or stabilisation fees we nd that size alone is not a reliable proxy for the systemic importance of a bank in this framework in order to smooth cyclical uctuations of the risk measure we explore a time varying condence level of the es

firm valuation earnings expectations and the exchange rate exposure effect consistent with previous research we fail to find a significant correlation between the abnormal returns of our sample firms with international activities and changes in the dollar we investigate the possibility that this failure is due to mispricing lagged changes in the dollar are a significant variable in explaining current abnormal returns of our sample firms suggesting that mispricing does occur a simple trading strategy based upon these results generates significant abnormal returns corroborating evidence from returns around earnings announcements as well as errors in analysts forecasts of earnings is also provided it is a widely held view that exchange rate movement should affect the value of a firm standard economic analysis implies that the profitability and value of most u s firms with foreign sales or operations abroad should increase decrease with an unexpected depreciation appreciation of the dollar as expected foreign currency cash flows translate into larger smaller u s

intergenerational transfers in philippine rice villages gender differences in traditional inheritance customs abstract this paper examines education land and nonland asset transfers from parents to children in five rice villages in the philippines a model with family fixed effects explains transfers better than either individual heterogeneity or observed parent and child characteristics without family fixed effects families facing different land constraints exhibit significantly different patterns of educational investment in children in a subsample with completed inheritance daughters receive less education land and total inheritance but are compensated with nonland assets parents also exhibit preferential behavior towards children of the same gender daughters of better educated mothers receive more land nonland assets and total inheritance better educated fathers give land preferentially to sons but favor daughters in education

crossing the lines the conditional relation between exchange rate exposure and stock returns in emerging and developed markets this paper examines the importance of exchange rate exposure in the return generating process for a large sample of non financial firms from 37 countries we argue that the effect of exchange rate exposure on stock returns is conditional and show evidence of a significant return impact to firm level currency exposures when conditioning on the exchange rate change we further show that the realized return to exposure is directly related to the size and sign of the exchange rate change suggesting fluctuations in exchange rates as a source of time variation in currency return premia for the entire sample the return impact ranges from 1 2 to 3 3 per unit of currency exposure and it is larger for firms in emerging markets compared to developed markets overall the results indicate that foreign exchange rate exposure estimates are economically meaningful despite the fact that individual time series results are noisy and many exposures are not statistically significant and that exchange rate exposure plays an important role in generating cross sectional return variation moreover we show that the relation between exchange rate exposure and stock returns is more consistent with a cash flow effect than a discount rate effect

nutrition and labor producvivity in agriculture estimates for rural south india using panel data for rural south india a fixed effects individual wage equation and farm production function are estimated that have calorie intake and nutritional status weight for height of workers as their arguments neither market wages nor farm output are observed to be responsive to changes in the daily energy intake of workers however both are highly elastic with respect to weight for height these results suggest that while the human body can adapt to inadequate nutrition in the short run it cannot adapt as readily to chronic malnutrition that eventually results in loss of weight for height copyright 1988 by mit press

another look at the role of the industrial structure of markets for international diversification strategies abstract this paper re examines the extent to which gains from international diversification are due to differences in industrial structure across countries recent papers by roll 1992 journal of finance 47 3 42 and heston and rouwenhorst 1994 journal of financial economics 36 3 27 investigate this issue and find conflicting evidence using a new database the dow jones world stock index with coverage in 25 countries and over 66 industry classifications we decompose comprehensively both country and industrial sources of variation we confirm that little of the variation in country index returns can be explained by their industrial composition we also uncover differences in the proportion of variation in industry index returns that is captured by country and industry factors and discuss the implications for global diversification strategies

international competition and exchange rate shocks a cross country industry analysis of stock returns this article systematically examines the importance of exchange rate movements and industry competition for stock returns common shocks to industries across countries are more important than competitive shocks due to changes in exchange rates weekly exchange rate shocks explain almost nothing of the relative performance of industries using returns measured over longer horizons the importance of exchange rate shocks increases slightly and the importance of industry common shocks increases more substantially both industry and exchange rate shocks are more important for industries that produce internationally traded goods but the importance of these shocks is economically small for these industries as well economists journalists and politicians around the world argue that some of the industries in their country compete vigorously with the same industries in other countries and that exchange rate shocks affect their competitiveness in the united states it is routinely stated that some u s industries compete with japanese industries and that a depreciation of the yen is bad for these u s industries and good for the rival japanese industries if the yen falls trade tensions could intensify between the u s and japan as autos and machinery from japan gain a competitive edge 1 further the exchange rate literature shows that exchange rate shocks lead to persistent deviations from purchasing power parity 2 froot and klemperer 1989 and knetter 1989 1993 among others demonstrate that deviations from purchasing power parity lead to sharp changes in price markups and profit margins for exporters

health enterprise and labor complementarity in the household we study the role of household enterprise as a coping mechanism after health shocks using variation in the cost of traveling to formal sector health facilities to predict recovery from acute illness in tanzania we show that individuals with prolonged illness switch from farm labor to enterprise activity this response occurs along both the extensive entry and intensive capital stock and labor supply margins family members who are not ill exhibit exactly the same pattern of responses deriving a simple extension to the canonical agricultural household model we show that our results suggest complementarities in household labor

price discrimination by u s and german exporters the insensitivity of the u s trade balance to the sharp depreciation of the dollar in the past three years has revived interest in the relationship between exchange rates and the trade balance a central issue in most analyses of the relation between the current account and the exchange rate concerns the price adjustment process the simple integrated competitive market model predicts that local currency prices should change in proportion to the nominal exchange rate for a country too small to influence world prices the relationship between local currency import prices and exchange rates has been referred to as the pass through relationship in the empirical literature in international economics if the proportional relationship between import prices and exchange rates holds pass through is said to be complete accounts of recent u s experience cite the failure of dollar prices of imported goods to rise in proportion to exchange rates i e incomplete pass through as an important factor in explaining the persistence of the trade deficit unfortunately observations on pass through alone provide limited insight into the behavior of markets since incomplete pass through is consistent with at least two fundamentally different paradigms one is the standard competitive model of trade in which the law of one price holds but exchange rate fluctuations are associated with large changes in import demand due to other factors for example if dollar appreciation is correlated with increases in world demand and industry marginal cost is increasing then pass through will be less than complete the other is an imperfectly competitive model in which exporters are capable of price discriminating across destination markets a phenomenon paul krugman 1987 has labeled pricing to market in this model incomplete pass through is typically associated with fluctuations in the markup of price over marginal cost on exports 2 these fluctuations in markups are believed to be countryspecific they do not reflect the behavior of prices to other export destinations both models are plausible explanations of recent u s experience unfortunately it is impossible to distinguish between these competing models using only information on import prices and exchange rates for a single country in order to distinguish between the competing models an empirical analysis of goods prices and exchange rates must be capable of measuring either marginal cost or the markup over marginal cost either of these tasks poses formidable empirical problems much of the empirical literature in industrial organization has been concerned with precisely these issues since markups are an important measure of the competitiveness of industries

program interventions intrahousehold distribution and the welfare of individuals modelling household behavior abstract in this essay the implications for the intrahousehold distribution of resources derived from economic models of household behavior that treat the household as maximizing a single welfare function are reviewed particular attention is paid to the within family allocation of time and food and to the effects of these resources on the schooling earnings and health status of individuals as they are affected by direct food intervention and female employment schemes and price altering policies empirical applications are provided from data sets from india indonesia and the philippines to illustrate the power and limitations of such models for illuminating household interventions and for placing restrictions on data

why do markets move together an investigation of u s japan stock return comovements this article explores the fundamental factors that affect cross country stock return correlations using transactions data from 1988 to 1992 we construct overnight and intraday returns for a portfolio of japanese stocks using their nyse traded american depository receipts adrs and a matched sample portfolio of u s stocks we find that u s macroeconomic announcements shocks to the yen dollar foreign exchange rate and treasury bill returns and industry effects have no measurable influence on u s and japanese return correlations however large shocks to broadbased market indices nikkei stock average and standard and poor s 500 stock index positively impact both the magnitude and persistence of the return correlations stock return cross country covariances play a key role in international finance changes in these covariances affect the volatility of portfolios and asset prices as these covariances increase one expects that a fewer domestic risks are internationally diversifiable so portfolio volatility increases b the risk premium on the world market portfolio increases 1 c the cost of capital increases for individual firms and d the domestic version of the capm becomes increasingly inadequate 2 despite the important economic consequences of changes in cross country covariances the determinants of the levels and dynamics of these covariances have been little studied from an academic

dynamic relations between international equity and currency markets the role of currency order flow previous research on the dynamic linkages between international financial markets focused on bivariate interequity or intercurrency relationships and do not allow a specific role for the currency or equity market respectively in this paper we hypothesize that there are important yet not well understood dynamic relationships between international equity and currency markets and these are driven by information spillover via the mechanism of currency order flow using a trivariate asymmetric garch framework we find that the relationships between equity and currency markets are significant bidirectional and pervasive these relationships which coexist with the relationships between u s and foreign equity markets are much stronger in the volatilities than in the means importantly we find strong support for our information spillover hypothesis where currency order flow is the economic mechanism by which information is transmitted

exchange rate exposure and industry characteristics evidence from canada japan and the usa abstract this paper examines industry level exchange rate exposures for canada japan and the usa measuring exposure by adding the change in the exchange rate to the domestic market model of industry portfolio returns some industries in all three countries display significant exposures moreover for each country the exchange rate is important for explaining industry returns at the economy wide level to explore whether exchange rate exposures are systematically linked to the activities of the industries we model exposure as a function of industry characteristics for all three countries the relation between exposure and industry characteristics is broadly consistent with economic theory jel f3

a dynamic analysis of exchange rate exposure the impact of china s renminbi this study examines the impacts of unexpected exchange rate movements of chinese renminbi cny usd on stock returns of standard poor s 500 corporations to gain better insight into the long standing exposure puzzle concerning the divergence between theoretical and empirical investigation and the critical issue regarding the determinants of exposure the time variation and asymmetry property associated with foreign exchange exposure are further taking into account we also broaden the scope of analysis to investigate unexpected risk exposure at 10 economic sectors in compliance with global industry classification standard unlike those from the static analysis or dynamic ones with the ordinary least squares model the empirical findings provide additional concrete evidence that unexpected exchange rate exposure varies substantially across time and market circumstances when using the quantile regression with a rolling method furthermore our dynamic analysis not only supports the existence of industrial effects across different economic sectors but also provides strong evidence that financial factors such as size debt ratio and book to market ratio have a significant impact on exposure

estimating the intrahousehold incidence of illness child health and gender inequality in the allocation of time in this paper the authors develop and implement a method for estimating the effects of infant morbidity on the differential allocation of time of family members based on discrete indicators of health and activity participation commonly available in survey data and within the context of a household model in which health is determined endogenously their estimates that take into account the simultaneity of health activity associations indicate that increased levels of infant morbidity significantly exacerbate existing differentials in the accumulation of human capital across teenage boys and girls in indonesia copyright 1990 by economics department of the university of pennsylvania and the osaka university institute of social and economic research association

industrial centralization in indonesia in certain situations economic liberalization policies can increase the degree of spatial centralization of resources and spatial concentration of manufacturing in large metropolitan areas in addition historical patterns of location make it difficult to alter the degree of centralization this article explores these issues by specifying and estimating a nested logit model of industrial location of manufacturing activity in java focusing on the unincorporated sector the results indicate that plants strongly prefer locations with mature plants in related industries which offer a built up stock of local knowledge in addition the 1983 liberalization in indonesia was associated with increased centralization of the unincorporated sector although the liberalization gave unincorporated firms better access to government and other centralized services firms needed to centralize to take advantage of these opportunities because the bureaucratic process is centralized and communications are poor the relative increased growth of the corporate sector following liberalization may also have helped to further draw unincorporated plants into centralized locations

the foreign exchange exposure of japanese multinational corporations we find that about 25 percent of our sample of 171 japanese multinationals stock returns experienced economically significant positive exposure effects for the period january 1979 to december 1993 the extent to which a firm is exposed to exchange rate fluctuations can be explained by the level of its export ratio and by variables that are proxies for its hedging needs highly leveraged firms or firms with low liquidity tend to have smaller exposures foreign exposure is found to increase with firm size we also find that keiretsu multinationals are more exposed to exchange rate risk than nonkeiretsu firms it is conventional wisdom that exchange rate movements affect both the cash flows of a firm s operations and the discount rate employed to value these cash flows measuring foreign exchange exposure is now a central issue of international financial management and this issue has spawned a considerable amount of research existing empirical evidence on foreign exchange exposure however seems perplexing studies have so far documented a weak link between contemporaneous exchange rate fluctuations and stock returns of u s multinational firms 2 gendreau 1994 finds it difficult and unconvincing that the weak results imply that exchange rate changes have no effect on exporters stock returns bartov arnd bodnar 1994 attribute the observed insignificant relationship between exchange rate changes and st ock returns to probable problems associated with the previous studies samiple selection procedure or to mispricing caused by investors errors in estimat

parental behavior and the value of children s health a health production approach data on individual children and on sibling pairs are used to examine how family resource allocations affect children s health and to estimate willingness to pay for reduced acute illness in children results highlight the importance of accounting for the endogeneity of child health and suggest that children with greater stocks of health capital whose parents invest in preventive and remedial medical care experience fewer days of illness estimated willingness to pay to avoid one day of illness induced school loss is about 100 to 150 a range broadly consistent with limited prior evidence but sub stantially more than unit values applied in recent policy analyses all else equal willingness to pay is higher among single parents and for uninsured children and the estimated income elasticity is only 0 14 implied aggregate benefits of reductions in children s sick time associated with air pollution control may be substantial

resolving the exposure puzzle the many facets of exchange rate exposure theory predicts sizeable exchange rate fx exposure for many firms however empirical research has not documented such exposures to examine this discrepancy we extend prior theoretical results to model a global firm s fx exposure and show empirically that firms pass through part of currency changes to customers and utilize both operational and financial hedges for a typical sample firm pass through and operational hedging each reduce exposure by 10 15 financial hedging with foreign debt and to a lesser extent fx derivatives decreases exposure by about 40 the combination of these factors reduces fx exposures to observed levels

education gender gaps in pakistan is the labor market to blame abstract differential labor market returns to male and female education are one potential explanation for large gender gaps in education in pakistan we empirically test this explanation by estimating private returns to education separately for male and female wage earners this article contributes to the literature by using a variety of methodologies ordinary least squares heckman correction two stage least squares and household fixed effects in order to estimate economic returns to education the latest nationally representative data the pakistan integrated household survey 2002 are used earnings function estimates consistently reveal a sizable gender asymmetry in economic returns to education with returns to women s education being substantially and statistically significantly higher than men s the return to an additional year of schooling ranges between 7 and 11 for men and between 13 and 18 for women there are also large direct returns to women s education at low levels of schooling

does industrial structure explain the benefits of international diversification abstract we examine the influence of industrial structure on the cross sectional volatility and correlation structure of country index returns for 12 european countries between 1978 and 1992 we find that industrial structure explains very little of the cross sectional difference in country return volatility and that the low correlation between country indices is almost completely due to country specific sources of return variation diversification across countries within an industry is a much more effective tool for risk reduction than industry diversification within a country

three new empirical tests of the pollution haven hypothesis when environmental regulation is endogenous the validity of existing empirical tests of the pollution haven hypothesis phh is constantly under scrutiny due to two shortcomings first the issues of unobserved heterogeneity and measurement error in environmental regulation are typically ignored due to the lack of a credible traditional instrumental variable second while the recent literature has emphasized the importance of geographic spillovers in determining the location choice of foreign investment such spatial effects have yet to be adequately incorporated into empirical tests of the phh as a result the impact of environmental regulations on trade patterns and the location decisions of multinational enterprises remains unclear in this paper we circumvent the lack of a traditional instrument within a model incorporating geographic spillovers utilizing three novel identification strategies using state level panel data on inbound u s fdi relative abatement costs and other determinants of fdi we consistently find i evidence of environmental regulation being endogenous ii a negative impact of own environmental regulation on inbound fdi in pollution intensive sectors particularly when measured by employment and iii larger effects of environmental regulation once endogeneity is addressed neighboring environmental regulation is not found to be an important determinant of fdi

arsenic mitigation in bangladesh a household labor market approach rural families in bangladesh one of the poorest countries in the world face financial risks from major illness both from the cost of medical care and from the loss of income associated with reduced labor supply and productivity chronic exposure to arsenic in drinking water has often been associated with the development of skin cancers and internal cancers especially of the bladder liver and lungs and a wide variety of other health conditions such as diabetes respiratory problems cardiovascular diseases hyperpigmentation hypopigmentation and keratosis a condition in which painful nodules grow on the palms of the hands and soles of the feet most of the economic work on arsenic contamination in bangladesh has had an epidemiological focus that has tried to effectively monetize a dose response relation using either a cost of illness or a willingness to pay approach

aids treatment and intrahousehold resource allocation children s nutrition and schooling in kenya this brief summarizes the results of a gender impact evaluation study entitled acquired immunodeficiency syndrome aids treatment and intra household resource allocation children s nutrition and schooling in kenya conducted in late 2003 till present in kenya the study observed the impact of antiretroviral arv medications to human immunodeficiency virus infection hiv or aids on the time allocated to various household tasks by treated hiv positive patients and their household members on the individual level treating adult aids patients with arv treatment results in substantial improvements in the welfare of children living with the patients after nine months of treatment the increases in school attendance are maintained with no significant drop off over the time period of study for boys in particular the increase in hours of attendance is almost exactly equal to the treatment driven decrease in their hours of market labor supply the short term nutritional status of young children in adult patients households improves significantly also within six months after treatment is initiated for the patients not presented separately for boys and girls these gains in nutritional status can be expected to improve the physical and cognitive abilities of children and eventually their post school productivity levels funding for the study derived from the economic and social research council pfizer the world bank yale university s center for interdisciplinary research on aids the national institute of mental health the social science research council and the calderone program at columbia university

health and wage a simultaneous equation model with multiple discrete indicators in this article we propose all econometric approach for estimating the simultaneouls effects of health and wages in a structural equations framework in the theoretical works of grossmana 1972a 1972b health is viewed as anl elldogen1oulsly determined capital stock the demand for health should rise with the wage rate as the rate of return to health investment increases with wage onl the other hand better health should raise market productivity and hence wages since health capital is an abstract theoretical concept it can hardly be measured quantitatively however most population surveys include various health indicators these indicators are usually discrete variables in the empirical work of grossman and benham 1974 these qualitative indicators are treated as continuous variables and two stage least squares estimation techniques are used this specification raises various econometric problems see e g goldberger 1964 pp 248 255 domencich and mcfadden 1975 and nerlove and press 1973 a satisfactory specification should take into account the discrete nature of the indicators our specification generalizes the dummy variables simultaneous equations system of heckman 1978 the measurement models of joreskog and goldberger 1975 and is closely related to the models of muthe n 1976 1979 muthen studies full information maximum likelihood procedures for estimation except for very simple cases this does not generally yield feasible or tractable procedures in this article we introduce a tractable procedure for statistical estimation and testing this specification and the estimation procedure is then applied to study the joint dependence of health and wages another departure of our approach from others is that we will test and correct the possible incompatibility of the various health capital indicators in the population surveys one may have subjective health indicators such as self evaluation of health which may reflect different populations perception of health we propose a statistical procedure for testing measurement compatibility and if required for correcting this problem this article is divided into two parts initially we describe the model specification estimation and statistical tests in a general simultaneous equation model with multiple discrete indicators in the second part of the paper we consider specification of a simultaneous equation model for health and wages the model

evaluating the effects of optimally distributed public programs child health and family planning interventions this paper develops and tests an optimizing model determining the distribution of family planning and health subsidies across heterogeneous households and assesses the biases in cross area estimates of the health effects of such subsidies due to public resource optimization the model incorporates both health externalities and the endogenous response of the size of the recipient population to program subsidies longitudinal data describing child health and publicly provided family planning and health programs in 20 barrios in laguna province in the philippines are used to estimate the effects of such programs on child health and the relationships between the distribution of the programs and preprogram health levels the impact of a program on a particular childs health status is viewed as dependent upon the childs length of exposure to the program a basic feature of the model is the presence of health externalities which is shown to be sufficient along with plausible features of household behavior to make selective subsidization of fertility control either alone or in combination with health investment subsidies pareto efficient the model suggests that subsidization of fertility control is likely to be pareto efficient in the presence of health or human capital externalities when human capital and family size are gross substitutes and or when any per child human capital subsidies may substitute for direct subsidies to health investment and an equalizing distribution of the subsidies the highest family planning subsidies to the lowest health recipient households is efficient when both health and family planning subsidies are used fertility control subsidies minimize the subsidy burden for donors and are highest when total subsidy expenditures per child are greatest

land inheritance and schooling in matrilineal societies evidence from sumatra abstract this paper explores statistically the implications of the shift from communal to individualized tenure on the distribution of land and schooling between sons and daughters in matrilineal societies based on a sumatra case study the inheritance system is evolving from a strictly matrilineal system to a more egalitarian system in which sons and daughters inherit the type of land which is more intensive in their respective work effort while gender bias is either non existent or small in land inheritance daughters tend to be disadvantaged with respect to schooling the gender gap in schooling however appears to be closing for the generation of younger children

early childhood nutrition schooling and sibling inequality in a dynamic context evidence from south africa abstract this article examines the effects of early childhood nutrition on schooling investments and outcomes to assess the dynamic nature of human capital production using panel data from south africa height for age z score is used as a measure of health and nutritional status in early childhood based on a comparison of siblings the empirical analysis shows that improving children s health significantly lowers the age when they start school increases grade attainment decreases grade repetition and improves learning performance in the early stage of schooling however the observed effect diminishes as a child ages which implies that i height at ages earlier than three better explains subsequent schooling outcomes and or ii the role of health capital changes from one schooling stage to another

internal funds and corporate investment in india abstract several economists have argued that capital markets in less developed countries are fragmented fragmented capital markets retard the efficient allocation of resources and force business firms to rely on internal sources of funds using firm level data the authors examine the importance of the accelerator internal funds and depreciation for investment by manufacturing firms in india the results indicate that internal funds and depreciation have significant explanatory power in a sales accelerator model of investment and that there exists heterogeneity among firms in the link between internal funds and investment in particular internal funds are relatively more important for large firms and firms that produce luxury goods

intrahousehold allocation of education expenditure the case of sri lanka abstract this article uses conventional engel curve demand analysis as well as a double hurdle model to explore whether there are intrahousehold differentials in the allocation of education expenditure between boys and girls in rural sri lanka contrary to the case in most developing countries in sri lanka there was a significant bias favoring girls for 1990 91 and 1995 96 for age group categories 8 9 14 16 and 17 19 and in 2000 for age group categories 14 16 and 17 19 significant differences in enrollment favoring girls aged 17 19 explain part of the girl bias observed in 1990 91 and 2000 2001 but most of the bias is driven by positive expenditure given enrollment the biases favoring girls are observed at critical stages of the schooling career in the run up to key national exams the 8 9 age group captures the run up to the year 5 scholarship exams that are used to gain entry to the better performing secondary schools the 14 16 and 17 19 age groups capture those who read for important nationa

exchange rate pass through when market share matters the authors investigate the pass through from exchange rates to import prices when firms future demands depend on their current market shares they show that profit maximizing foreign firms may either raise or lower their dollar export prices when the dollar appreciates temporarily i e the pass through may be perverse and that current import prices may be more sensitive to expected future exchange rates than to current exchange rates they present evidence that suggests the behavior of expected future exchange rates may provide a clue to the puzzling recent behavior of u s import prices copyright 1989 by american economic association

the exchange rate exposure of u s multinationals this article examines the exposure of u s multinationals to foreign currency risk evidence is presented that the relationship between stock returns and exchange rates differs systematically across multinationals given these results the study focuses on the determinants of exchange rate exposure the comovements between stock returns and the value of the dollar is found to be positively related to the percentage of foreign operations of u s multinationals copyright 1990 by the university of chicago

women work and weil being in the middle east an outline of the relevant literature there is now an extensive literature on the role of women in economic development and the impact of development on their lives this article concentrates on the economic literature and discusses its importance for policies aimed at working women in the middle east it identifies the important strands and places the discussion within the wider context of women in the labour market in both developing and developed countries the general conclusion is that we are very far from having sufficient knowledge to implement effective policy or even to evaluate existing policies

endowments and the allocation of schooling in the family and in the marriage market the twins experiment 03 we show how comparisons between the within twin correlations of human capital outcomes across identical and nonidentical twins can be used to identify the variability in the individual specific component of endowments and the responsiveness of schooling to individual specific endowments in the family and in the marriage market even when schooling is measured with error estimates from two twins samples indicate that 27 42 percent of the variance in log earnings obesity is due to variability in individual specific endowments allocations of schooling reinforce specific endowments and individual specific earnings endowments of men and their wives schooling are negatively associated

migration selectivity and the effects of public programs abstract a model of the spatial distribution of mobile heterogeneous agents is formulated to assess how a price change or program subsidy that is location specific affects the composition of local residents via selective migration and thus biases evaluations of the effectiveness of the program based on its local consequences longitudinal data from colombia are used to test the implications of migration selectivity the findings confirm the existence of selective migration suggesting that local subsidies to human capital attract high income but within income groups low fertility households and those with low human capital endowments these migration patterns are shown to be consistent with the dominance of endowment over tastes heterogeneity in the population under plausible behavioral assumptions

linear and nonlinear exchange rate exposure abstract this paper presents a new methodological approach to examine exchange rate exposure which takes account of the role of the market portfolio and macroeconomic variables in exposure regressions exchange rate regimes based on periods of depreciation and appreciation and nonlinear exposure within each regime we show that the stock market s own exposure to exchange rates should be taken into account before considering industry exposure in addition we adjust the exchange rate and the stock market for common economy wide factors that are unrelated to exchange rates within this framework we show that exposure to bilateral exchange rates is statistically and economically important and that industries with extensive international trade are more often exposed than industries with low levels of international trade the signs of exposure coefficients in each regime are consistent with the extent to which an industry exports we also show that nonlinear exposure is often statistically and economically significant interestingly there is little evidence that industries are exposed to a currency basket

pass through and exposure firms differ in the extent to which they pass through changes in exchange rates into foreign currency prices and in their exposure to exchange rates the responsiveness of their profits to changes in exchange rates because pricing affects profitability a firm s pass through and exposure should be related this paper develops models of exporting firms under imperfect competition to study these related phenomena from these models we derive the optimal pass through decisions and the resulting exchange rate exposure the models are estimated on eight japanese export industries using both the price data pass through and financial data for exposure exchange rates can have a major inf luence on the pricing behavior and profitability of exporting and importing firms firms differ in the extent to which they pass through the change in exchange rates into the prices they charge in foreign markets they also differ in their exposure to exchange rates the responsiveness of their profits to changes in exchange rates previous papers have studied either pass through or exposure but none has studied these two phenomena together yet because pricing directly affects profitability the exposure of a firm s profits to exchange rates should be governed by many of the same firm and industry characteristics that determine pricing behavior this paper develops models of firm and industry behavior that are used to study these closely related phenomena together it also provides estimates of pass through and exposure behavior using data from japanese export industries to examine pass through behavior and exchange rate exposure we model a firm with sales to a foreign export market this exporting firm competes with a foreign firm in that export market the costs of the exporting firm are based primarily in the local domestic currency while the foreign firm

the effects of human capital on wages and the determinants of labor supply in a developing country abstract the heckman procedure is used to correct for sample selection bias in estimating wage offer and net labor market supply equations the findings show that wages are affected by education and experience in addition the wage offer is influenced by other genetic and environmental influences captured in the wage of one s father calories as predicted by exogenous instruments are also shown to influence the wage offer suggesting that better nutrition increases labor productivity the probability of market labor participation as well as the amount of net market labor supply declined with the size of paddy landholding in addition to the net market supply elasticity increasing with the amount of land owned and being lower for urban than rural workers

gender bias investments in children and bequests the impacts of pure sex preference and differential earnings opportunities by gender on investments in children are modelled with altruism if bequest constraints do not bind human investments are privately efficient with the higher earning gender receiving more education education does not depend on parental wealth the gender differential in bequests is ambiguous however even in this case when bequest constraints bind education may depend on wealth and it is also possible for the gender with better earnings opportunities to get less education the model is tested with data from philippine villages where bequest constraints are generally nonbinding the schooling differential slightly favors daughters estimated bequest behavior however reflects pure sex preference in terms of our model copyright 1995 by economics department of the university of pennsylvania and the osaka university institute of social and economic research association

what policies will reduce gender schooling gaps in developing countries evidence and interpretation summary this paper considers evidence for the effects of policies on gender gaps in education distinguishing between policies that are ostensibly gender neutral and those that explicitly target girls the demand for girls schooling is often more responsive than boys to gender neutral changes in school distance price and quality patterns which can be explained in a human capital investment model through assumptions about girls and boys schooling costs and returns among policies that target girls enrollments price incentives to households or schools and the provision of female teachers appear to be effective other interventions hold promise but have not been the subject of rigorous evaluation pointing to an important agenda for future research

international comparisons of pricing to market behavior this paper measures the degree of price discrimination across export destinations that is associated with exchange rate changes using u s u k german and japanese industry level data given the industries sampled more price discrimination across destinations is observed in the u k german and japanese data for industries that match across source countries however behavior is very similar across source countries furthermore destination specific price adjustment on exports to the united states from germany and japan is similar to price adjustment observed on shipments to other destinations most variation in the data appears to be related to industry copyright 1993 by american economic association
