fuel consumption for road transport in the usa abstract this study provides both a historical analysis of fuel demand for road transport and an example of using econometric results for projections fuel consumption by all motor vehicles in the usa has been analysed by splitting total demand into passenger car truck and other demands distance travelled and fuel efficiency equations have been estimated for both the passenger car fleet and trucks an essentially five equation model has been constructed and used to simulate likely fuel demand patterns up to 1990

global educational expansion and socio economic development an assessment of findings from the social sciences summary among development agencies conventional wisdom holds that educational expansion improves economic welfare and health reduces inequalities and encourages democratic political systems we investigate the empirical foundations for these expectations in recent social science research consistent evidence indicates that health and demographic benefits result from educational expansion and suggests that education enhances but does not ensure individuals economic security however the impact of educational expansion on growth remains debated and decades of sociological studies offer evidence that educational expansion does not necessarily narrow social inequalities finally considerable controversy surrounds the implications of educational expansion for democratization reasonable forecasts of the consequences of further educational expansions need to consider the diverse social contexts in which these expansions will occur

the demand for gasoline abstract sufficient time must be allowed to elapse to assess fully the response of gasoline demand to price changes hitherto empirical work on the subject has generally not examined the period beyond 1975 moreover the extant time series studies concentrate almost exclusively on the usa this study extends both the observation period and the country coverage a vehicle stock adjustment model is estimated via its reduced form without explicit consideration of the vehicle stock itself however the estimation procedure incorporates the structure by way of constraints on the parameters cross section analysis offers additional evidence concerning the truly long run price elasticity the results suggest that there is no need to resort to elaborate models to explain adequately gasoline demand gasoline demand exhibits a long run price elasticity near unity with time lags exceeding six years while there is tentative evidence that the duration of these lags is not fixed

women s work and economic development using a cross country dataset and microdata from india and thailand we examine how women s work status changes with economic development several clear patterns emerge women s labor force participation first declines and then rises with development women move from work in family enterprises to work as paid employees fertility declines and gender gaps in education narrow women s education levels and those of their spouses appear to be important determinants of women s labor market activities broad welfare indicators such as mortality rates and education levels indicate that women s well being improves on average with development both in absolute terms and relative to men

child fostering in africa when labor and schooling motives may coexist abstract the paper proposes a theoretical framework for understanding purposive child fostering in africa whereby a non orphaned child is sent to live temporarily with relatives in the model adults decide whether to foster in or out a child in conjunction with other household choices e g own time allocation between market and non market activities children s amount of work and schooling by allowing for positive externalities from fostering and thus asymmetric motives for fostering in labor and out human capital the proposed framework predicts that school age children are sent to better off households and that some families may foster in and out simultaneously the model identifies the conditions under which all actors involved children included may benefit from fostering arrangements but also points to situations where fostering may become an opportunity to marginalize a subset of children the paper aims to provide a sound theoretical foundation that sheds light on why there exists mixed empirical evidence on the effects of fostering on children s well being and cautions against demonizing non parent residence as unequivocally detrimental to children

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

intra household gender disparity in school choice evidence from private schooling in india abstractthis paper explores gender inequality within households in the decision of private versus government school choice in india using a three period longitudinal dataset on rural households from uttar pradesh a northern state of india this paper estimates a household fixed effects model and finds that there is an intra household gender bias of 6 percentage points in private school enrolment among children aged 6 16 years contrary to the trend in overall enrolment the gender gap in private school choice is rising over time and is more pronounced in villages with a larger cost difference between private and government schooling this finding remains robust even after controlling for average school quality and considering potential endogeneity of the cost variables

input choices in agriculture is there a gender bias summary this paper examines evidence of gender biases in the decisions of agricultural households utilizing data from international crops research institute for the semi arid tropics s village level studies in india 1975 85 the main empirical finding is that households with a high proportion of boys tend to use some agricultural inputs including fertilizers and irrigation services more intensively than households with girls this pattern is more pronounced among wealthier households but does not appear to be driven solely by bequest motives or male child labor productivity

exploring the interaction between stock price index and exchange rates an asymmetric threshold approach this article examines the impact of stock market news on the foreign exchange markets of usa canada and uk employing an innovative extension of the asymmetric threshold model of apergis and miller 2006 under this framework we can disentangle the reaction of foreign exchange market to bad or good news and small or large news of stock returns our comprehensive daily data set spans the period from january 1990 to june 2014 using a cointegration and error correction model we document the existence of a causal relationship between stock market and foreign exchange markets most interestingly our results derived from the asymmetric threshold model confirm that the relationship between stock and foreign exchange markets is sensitive to short term good or bad news and short term small or large news our findings entail significant implications for policymakers governments risk managers and international investors

intrahousehold inequality and the theory of targeting the two literatures on targeting and on intrahousehold inequality have developed rapidly over the past 15 years but largely independent of each other the literature on targeting concerns itself with the design of tax and transfer programs for poverty alleviation in the presence of limited information on who the poor are the literature on intrahousehold inequality arose out of a dissatisfaction with unitary models of the household especially in explaining inequality in consumption and achievements of different household members even after allowing for relevant differences among them the authors begin to forge the link between the two literatures so they can address issues policymakers face around the world after a brief reprise of the key features of the two literatures they indicate how the presence of intrahousehold inequality and allocation mechanisms could affect the standard analysis of targeting theory they conclude with a list of policy questions for further research this abstract was borrowed from another version of this item

child labor in the global economy few issues in developing countries draw as much popular attention as child labor this paper begins by quantifying the extent and main characteristics of child labor it then considers the evidence on a range of issues about child labor fundamentally child labor is a symptom of poverty low income and poor institutions are driving forces behind the prevalence of child labor worldwide this study concludes by assessing the policy options to reduce worldwide child labor

consumption asymmetry and the stock market empirical evidence abstract this paper examines whether u s stock market value affects consumption asymmetrically using cointegration and error correction methodology the results confirm that stock market value asymmetrically affects real per capita consumption negative news affects consumption more than positive news

counting and multidimensional poverty measurement this paper proposes a new methodology for multidimensional poverty measurement consisting of an identification method k that extends the traditional intersection and union approaches and a class of poverty measures m our identification step employs two forms of cutoff one within each dimension to determine whether a person is deprived in that dimension and a second across dimensions that identifies the poor by counting the dimensions in which a person is deprived the aggregation step employs the fgt measures appropriately adjusted to account for multidimensionality the axioms are presented as joint restrictions on identification and the measures and the methodology satisfies a range of desirable properties including decomposability the identification method is particularly well suited for use with ordinal data as is the first of our measures the adjusted headcount ratio we present some dominance results and an interpretation of the adjusted headcount ratio as a measure of unfreedom examples from the us and indonesia illustrate our methodology

real income equivalence among one earner and two earner families in an earlier paper we proposed a technique for making income comparisons across various household sizes in this paper we employ a modified version of that method to convert nominal income to some real equivalent comparable across families of a given size but with one or two family earners we begin with a discussion of some of the conceptual difficulties involved in making cross family size or structure comparisons in income we then describe spending pattern differences between one and two earner families the final section discusses our effort to convert nominal income into comparable real income units we conclude that nominal income differences between two and one earner families far overstate differences in standards of living excerpt

the stock market and exchange rate dynamics abstract this paper articulates a model of the open economy in which as in tobin 1978 the price of shares in the stock market subtitutes for the real interest rate in the determination of aggregate demand the stock market reduces the impact of monetary policy on the real exchange rate indeed if the link between stock prices and aggregate demand is important enough the impact of monetary policy on the real exchange rate can be reversed in contrast with standard dynamic mundell flemming models anticipated fiscal policy can be expansionary rather than contradictionary as in for example burgstaller 1983 blanchard 1984 and branson et al 1985

looking for boy girl discrimination in household expenditure data the ability to test for discrimination in the allocation of goods between boys and girls is hampered by a lack of data on intrahousehold distribution the analysis presented here allows inferences about intrahousehold allocation to be made from householdlevel expenditure data for a given level of income families with children will spend less on adult goods in order to purchase children s goods if household purchasing favors boys over girls smaller expenditures on adult goods would be made by families with boys as compared with those with girls a method for determining adult goods is described and the procedure for detecting gender bias is applied to data from c6te d lvoire and thailand the data show no evidence of discriminatio n between boys and girls in c6te d lvoire and a small and statistically insignificant bias in favor of boys in thailand how commodities are allocated among the members of a household has recently occasioned a good deal of interest assessments of poverty and income distribution based on household incomes or expenditures will be misleading if allocation within the household is unequal the position of women and girls has been of particular concern and there is a considerable amount of empirical evidence much of it from the indian subcontinent that documents discrimination against females see in particular bhagwati 1973 sen 1984 sen and sengupta 1983 miller 1981 bardhan 1982 and kynch and sen 1983 as well as survey papers by behrman 1987 and harriss 1987 much of the evidence is concerned with measurements of nutritional outcomes mortality and health status rather than with the direct allocation of goods by gender the difficulty in trying to determine the intrahousehold allocation of goods is that household budget surveys the obvious source of data record consumption not of individuals but of households and while attempts can be made to the author is a professor of public affairs and of economics and international affairs at princeton university and is a consultant to the population and human resources department of the world bank the author thanks dwayne benjamin who provided for excellent research assistance he is grateful to him and to members of the economic growth center at yale university for helpful comments this is a revised and shortened version of living standards measurement study working paper 39 the allocation of goods within the household adults children and gender june 1987 the results from thailand were not included in the working paper 1989 the international bank for reconstruction and development the world bank

enduring poverty and the conditions of childhood lifecourse and intergenerational poverty transmissions abstract in this paper we explore the conditions of childhood that can lead to poverty throughout the lifecourse and affect transfers of poverty to the next generation the largely inconclusive evidence base surrounding lifecourse and intergenerational poverty transmission is reviewed before a discussion of the key social processes and contexts that impact on childhood lifecourse and intergenerational poverty prioritized issues nutrition childcare and guidance education child work and aspirations and attitudes are explored within the context of unicef s basic framework of survival protection development and participation the paper concludes with an analysis of elements of the wider environment critical to enabling action in childhood to break poverty cycles

fuel consumption for road transport in the usa a comment abstract a recent article in this journal econometrically estimated the relationship between us car and truck fuel economy and the price of fuel without considering the effect of legally mandated fuel economy standards for new vehicles there is considerable evidence that the standards have played an important role in recent fuel economy improvements an alternative approach to estimating the fuel price responsiveness of new vehicle fuel economy based on vehicle sales data and capital operating cost trade off analysis of fuel efficient vehicle design and technology suggests short and long run elasticities in the vicinity of 0 25 and 0 5 respectively

how serious is the neglect of intrahousehold inequality in this report the authors develop a framework for assessing the consequences of ignoring intrahousehold inequality in the measurement and analysis of poverty and inequality they apply this framework to data for the philippines and conclude that 1 the result of neglecting intrahousehold inequality will probably be considerable understatement of the levels of poverty and inequality with the philippine data measured levels of inequality and poverty were off 30 percent as a result of ignoring intrahousehold variation and 2 patterns of inequality revealed by household level data are somewhat different from patterns revealed by individual level data but the differences seem not to be dramatic to confirm these results the exercise should be repeated with data from other countries

traditional vs modern production systems price and nonmarket considerations of cacao producers in northern ecuador many factors besides profit maximization such as nonmarket ecological and social benefits influence smallholder households to adopt a specific agricultural production system or sell in a particular market thus different analytical techniques are needed that take into consideration more than monetary income to fully capture these additional benefits to better understand the production decisions of smallholder farmers we build on previous work on the household model and shadow wage estimation to develop a shadow wage for ecuadorian cacao producers that includes these nonmarket benefits we found that the shadow wage correctly indicated that on average these households would prefer to use an agroforestry production system instead of the more profitable modern system because of the nonmarket benefits received from the former system

the demand for petrol with explicit new car fuel efficiency effects a uk study 1977 86 abstract a full quarterly model for the demand for petrol motor gasoline is presented which deals with problems of seasonality in price and volume it is shown that the annual new car fuel consumption rate can be incorporated in modelling demand for petrol and this allows a better representation of the structure and mean speed of response of demand to price effects by separately specifying a new car fuel parameter the estimated short run price elasticity is 0 18 after three months rising to 0 2 after a year without such specification the elasticity reduces to 0 14 after three months 0 12 after a year the difference is discussed and interpreted as compensation due to the new car effect the new model year car fuel elasticity is defined and found to be about 0 1 in the sense that a 10 decrease in l 100 km 10 increase in efficiency over the previous model year decreases total petrol demand by 1 by endogenizing both petrol price and volume in a simultaneous system it is possible to identify a supply model for petrol volume in terms of the now endogenous petrol price to give a long run supply elasticity of about 0 4

intergenerational persistence in health in developing countries the penalty of gender inequality this paper is motivated to investigate the often neglected payoff to investments in the health of girls and women in terms of next generation outcomes this paper investigates the intergenerational persistence of health across time and region as well as across the distribution of maternal health it uses comparable microdata on as many as 2 24 million children born of about 0 6 million mothers in 38 developing countries in the 31 year period 1970 2000 mother s health is indicated by her height bmi and anemia status child health is indicated by mortality risk and anthropometric failure we find a positive relationship between maternal and child health across indicators and highlight non linearities in these relationships the results suggest that both contemporary and childhood health of the mother matter and that the benefits to the next generation are likely to be persistent averaging across the sample persistence shows a considerable decline over time disaggregation shows that the decline is only significant in latin america persistence has remained largely constant in asia and has risen in africa the paper provides the first cross country estimates of the intergenerational persistence in health and the first estimates of trends

gender agricultural production and the theory of the household virtually all models of the household assume that the allocation of resources is pareto efficient within many african households agricultural production occurs on many plots controlled by different members of the household pareto efficiency implies that factors should be allocated efficiently across these plots i find in contrast that plots controlled by women are farmed much less intensively than similar plots within the household controlled by men the estimates imply that about 6 percent of output is lost because of inefficient factor allocation within the household the paper suggests a new approach to modeling intrahousehold allocation consistent with the empirical results

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

plastic cars in china the significance of production location over markets for technology competitiveness in the united states versus the people s republic of china abstract this paper demonstrates the significance of location specific differences in manufacturing characteristics and in consumer demand for technology competitiveness it looks in particular at the economic viability of emerging polymer composite automobile body technologies if produced in the united states u s versus if produced in the people s republic of china p r c the results show that polymer composite bodies when produced locally for the local market are competitive for significantly fewer cars in the p r c 7 than in the u s 29 despite consumer demand characteristics in the p r c being more favorable for composites differences in production characteristics between the two locations dominate the overall effect these results suggest that in cases such as automobile bodies where markets and manufacturing location are tightly coupled firms may need to put as much emphasis on understanding the impact of local production differences on technology competitiveness as in understanding local markets

intrahousehold inequalities in child rights and well being a barrier to progress this paper uses unicef s multiple indicators cluster surveys cross country data to shed light on unequal investments in the wellbeing of children boys and girls within the household the paper proposes a new methodology to measure the extent of gender intrahousehold inequality and its contribution to overall levels of inequality using an l theil index decomposition the individual and joint distribution of inequality in four key indicators of child wellbeing is analyzed stunting birth registration school attendance and time spent on work and chores working hours in the search for evidence of gender bias evidence from various separate county studies had shown that the direction of the gender bias is not universal such conclusion holds when using a consistent methodology and comparable cross country datasets this paper shows that disparities inside households do not follow the same bias toward one or the other gender in all countries and the direction of the bias is not the same across indicators of wellbeing while progress in improving child wellbeing has occurred in many countries inequalities remain intrahousehold inequalities might still be considered a priority in an agenda focused on closing these progress gaps

fuel demand on uk roads and dieselisation of fuel economy abstract because of high oil prices and climate change policy governments are now seeking ways to improve new car fuel economy thus contributing to air quality and energy security one strategy is to increase dieselisation rates of the vehicle fleet recent trends in fuel economy show improvement since 1995 however efforts need to go further if the eu voluntary agreement targets on co 2 a greenhouse gas emission standard are to be achieved trends show diesel car sales have accelerated rapidly and that the advantage of new car fuel economy of diesel cars over gasoline ones is narrowing posing a new challenge we estimate the demand for new car fuel economy in the uk in the long run consumers buy fuel economy but not in the short run we found that long term income and price changes were the main drivers to achieve improvements particularly for diesel cars and that there is no break in the trend of fuel economy induced by the agreement adopted in the 1990s policy should target more closely both consumer choice of and use of diesel cars

market opportunities genetic endowments and intrafamily resource distribution child survival in rural india the authors examine how intrafamily resource allocations respond to changes in economic conditions and to genetic differences in children by estimating the determinants of variations in the sex specific survival differentials of rural indian children based on standard census and household survey data they explore in particular the hypothesis that such differences are related to the relative returns to survival with households selectively allocating resources to children in response to variation in sex differences in their expected earnings opportunities as adults data are from the 1961 census and a 1971 household survey excerpt

gender differences in land inheritance schooling and lifetime income evidence from the rural philippines this article examines the difference in lifetime incomes arising from parental preferences in the allocation of land inheritance and investments in schooling between sons and daughters in the rural philippines sons are preferred with respect to land inheritance receiving 0 15 additional hectares of land while daughters are treated more favourably in schooling investments receiving 1 5 more years of schooling however differences in both current and life cycle incomes between sons and daughters are insignificant this suggests that filipino parents allocate intergenerational transfers to equalise incomes among their children without sacrificing efficiency

gender and multidimensional poverty in nicaragua an individual based approach most existing empirical papers concerned about multidimensional poverty use the household as the unit of analysis so that the multidimensional poverty status of the household is equated with the multidimensional poverty status of all its members this assumption ignores intra household inequalities additionally households containing both a female and a male cannot contribute to a gender gap in poverty so gender differentials in poverty cannot be estimated but the sustainable development goals have put special emphasis on gender equality therefore new measures able to capture the gender differences are needed consequently in this paper we propose an individual based multidimensional poverty measure in order to estimate the three i s of multidimensional poverty incidence intensity and inequality in nicaragua as well as the gender differentials we also estimate logit regressions to better understanding the determinants of multidimensional poverty in this country overall we find that there are statistically significant gender differences in multidimensional poverty in nicaragua but they are estimated to be small and lower than 5 however the gender differential in inequality is larger than 10 and it suggests that multi dimensionally poor women are living in very intense poverty when compared with multi dimensionally poor men we also find that the elderly and children are the most vulnerable people in terms of multidimensional poverty in this country furthermore when information on employment domestic work and social protection is considered in the analysis the gender gaps become more substantial and women are more likely to be poor than men

do parents favor boys in an optimizing model of parental allocation systematic differences in human capital investments betwen the sexes may originate in at least 3 ways 1 parents may respond to expected gender wage differentials 2 parents may respond to systematic differences by gender in the price of human capital investments 3 parental preferences may favor girls or boys in the sense that they value identical outcomes at the same cost more highly for one sex than for the other this paper analyzes the role of parental preferences in general and unequal concern in particular in the allocation of human capital investments among children the authors generalize their earlier model of the human capital investments among children to incorporate the possibility that the returns to such investments may include not only the childs own ecpected earnings but also the expected earnings of his or her spouse thus the model assumes that parents may value returns that accrue trough the marriage market as well as through education the relevant returns to education may include marrying a spouse with higher expected earnings the empirical analysis indicates that gender wage differentials like endowment differentials are mildly reinforced by the parental allocation of human capital investments marriage market outcomes are significant determinants of the allocation of human capital investments among children there is no evidence that parental preferences favor boys this study shows that parental preferences either exhibit equal concern or slightly favor gils

towards a theory of famine relief policy abstract this paper examines how famine mortality is related to the distribution of food consumption a theoretical model is proposed of how individual survival chances are affected by changes in consumption uncertainty in survival prospects arises from the errors made by any observer in assessing health at given current consumption the theory is used to explore two policy issues in famine relief the choice of budgetary rules for allocating emergency aid and the case for price stabilization policies during famines applications to data for two famines in south asia suggest that successful price stabilization would have had substantial benefits in reducing mortality
