reputational capital opportunism and self policing in legislatures this paper examines the question of whether reputational capital can deter opportunistic behavior among legislators preparing to exit the house of representatives i create a measure of reputational trustworthiness based upon pooled samples of constituency opinion derived from the national election studies surveys i then examine the extent to which such reputational good will among constituents deters lame duck foreign travel by exiting house incumbents within the context of a quasi experimental research design the analysis suggests that legislators may be self policed by their reputations for honesty and trustworthiness to the point of discouraging unethical activity urveys i then examine the extent to which such s derived from the national election studies

marriage bequest and assortative matching in rural ethiopia abstract this article examines the determinants of human and physical capital at marriage using detailed data from rural ethiopia we find that assets brought to marriage are distributed in a highly unequal manner for first unions assets brought to marriage are positively associated with parents wealth indicating that a bequest motive affects assets at marriage parental wealth affects the inheritance of neither groom nor bride sibling competition from brothers affects grooms inheritance but sisters have no effect the marriage market is a major conduit for rural and gender inequality although avenues do exist for couples to accumulate wealth over their life cycle

measuring returns on investments in collectibles this paper considers the question of how to measure and interpret the financial return to investing in collectibles we review various methodologies for creating priced indexes and then discuss studies that explicitly calculate a rate of return to some set of collectibles while most collectibles appear to yield positive real returns the majority embody more risk and yield lower financial returns than stocks other characteristics of collectibles prices such as covariance with other asset prices are also examined

women s schooling home teaching and economic growth the hypothesis that increases in the schooling of women enhance the human capital of the next generation and thus make a unique contribution to economic growth is assessed on the basis of data describing green revolution india estimates are obtained that indicate that a component of the significant and positive relationship between maternal literacy and child schooling in the indian setting reflects the productivity effect of home teaching and that the existence of this effect combined with the increase in returns to schooling for men importantly underlies the expansion of female literary following the onset of the green revolution

fdi as an outcome of the market for corporate control theory and evidence abstract much foreign direct investment fdi takes the form of mergers and acquisitions m a it is commonplace in finance to view acquisitions as manifestations of the market for corporate control following on that insight we propose a model of fdi in which headquarters bid to control overseas assets we derive an equation for bilateral fdi stocks that resembles the recently developed fixed effects approach to modelling bilateral trade flows we estimate the model and use its parameters to construct benchmarks for evaluating multilateral inward and outward fdi

shirking and political support in the u s senate 1964 1984 several empirical studies have suggested that legislators engage in a surprisingly large degree of on the job consumption or ideological behavior these findings cast doubt on the hypothesis that legislators can be modelled as though they seek to maximize political support this paper attempts to determine whether commonly used proxies for ideology in fact represent behavior to which voters are averse the results show that legislators who engage in more of this behavior lose general election support without generally receiving compensating increases in partyprimary support a corollary to this result is that voters punish shirking legislators significantly

how efficient is the voting market it is by now well established that good macroeconomic conditions benefit the incumbent president and his congressional party confreres at the polls this result is not unanimous see for example stigler or arcelus and meltzer2 and may not be universal 3 however the basic results in kramer 4 the progenitor of the modern literature on the effect of economic conditions on elections seem to have stood the test of time the broad consensus of this literature is that voters in presidential and congressional elections 1 reward income growth and punish unemployment and inflation 2 probably give greater weight to income growth than to unemployment and inflation and 3 myopically ignore any information beyond the recent past say prior to the election year 5 so far however the data have outrun interpretation while economic conditions seem to matter we do not know why they matter or how plausibly to characterize the process by which voters translate information about economic conditions into voting decisions this article tries to fill that gap though it extends the empirical literature to gubernatorial elections its main con

what separates us sources of resistance to globalization with increasing sophistication economists have been estimating gravity equations for five decades robust evidence shows that borders and distance impede trade by much more than tariffs or transports costs can explain we therefore advocate investigation of other sources of resistance despite the greater difficult involved in measuring and modelling them from our selective review of recent findings a unifying explanation emerges a legacy of historical isolation and conflict forged a world economy in which neither tastes nor information are homogeneously distributed cultural difference and inadequate information manifest themselves most strongly at national borders and over distance

shirking and sorting in a political market with finite lived politicians this paper analyzes principal agent slack in the context of a political market composed of voters challengers and incumbents the introduction of a last period via finite livedness in combination with voters imperfect information about politicians preferences causes time varying shirking behavior on the part of politicians political markets eventually sort out those politicians with significantly deviant policy preferences potentially providing a solution to the last period problem and enabling politicians to make credible commitments in the extreme sorting can insure that it is not worthwhile for potential shirkers to run for office a systematic relationship between political shirking and number of terms in office may exist and depends on how quickly sorting takes place we show that evidence of little if any shirking is quite consistent with politicians having diverse and strongly held policy preferences in addition if sorting is a significant feature of political markets cross sectional studies will tend to oversample little and non shirking politicians compared to longitudinal studies reinterpretations of existing empirical work are also discussed

intrahousehold distribution and poverty evidence from cote d ivoire poverty measures often ignore the distribution of resources within families and the gains from joint consumption in this paper we estimate the allocation process and adult economies of scale in households from cote d ivoire using a collective model of household consumption identification relies on the observation of adult specific goods as in the rothbarth method and a joint estimation on couples and singles our results show that men and women s shares of total expenditure are of the same order of magnitude and children s shares are small scale economies are large and affect poverty measures

l etranger status property rights and investment incentives in cote d ivoire this study uses data from cote d ivoire to show that outsider households have relatively small land holdings and less complete rights over land than locals it then demonstrates a link between property rights and investment incentives by looking at the decision to leave land fallow outsiders fallow a smaller proportion of their land indicating that their farms are left uncultivated for shorter periods this is only partly explained by their incomplete property rights and relative land poverty these differences in investment patterns lead to lower yields per hectare jel o12 q15

bride price and fertility decisions evidence from rural senegal abstractthis paper provides evidence about the relationship between bride price payments and fertility decisions in senegal higher bride price payments reduce the fertility pressure for women with results being robust to confounding socio economic and contextual factors the fertility reducing impact is greater for women who are economically dependent on their husbands in polygamous households and for arranged marriages a lower bride price increases fertility pressure while in monogamous households and for non arranged marriages the bride price does not affect fertility as bride price payments have less power over economically independent women empowerment will give leeway to girls in traditional societies

hedging price volatility using fast transport abstract purchasing goods from distant locations introduces a significant lag between when a product is shipped and when it arrives these transit lags are trade barriers for firms facing volatile demand who must place orders before knowing the resolution of demand uncertainty we provide a model in which airplanes bring producers and consumers together in time fast transport allows firms to respond quickly to favorable demand realizations and to limit the risk of unprofitably large quantities during low demand periods the model predicts that the likelihood and extent to which firms employ air shipments is increasing in the volatility of demand they face decreasing in the air premium they must pay and increasing in the contemporaneous realization of demand we confirm all three conjectures using detailed us import data fast transport thus provides firms with a real option to smooth demand volatility on international markets and we provide simple calculations of that option value this enables us to identify how the option value relates to goods characteristics and to changes in air transport premia associated with technological and policy change including the introduction of jet engines and liberalization of trade in air services

new roles for marriage in urban africa kinship networks and the labor market in kenya abstract this paper explores new roles that traditionally rural kinship networks organized around the marriage institution might play in improving labor market outcomes in urban africa using new data from kisumu kenya and controlling for selection into marriage we find that marriage significantly increases employment levels and incomes in our sample of migrants at the same time marriage increases the remittances that migrants send to the extended family consistent with the view that the benefits of the network come with additional social obligations these obligations appear to be borne disproportionately by high ability individuals who consequently defer marriage the negative selection into marriage that we uncover has consequences for the future viability of the urban networks with implications for long term growth and distribution in this economy

rising trade costs agglomeration and trade with endogenous transaction costs while transport costs have fallen the empirical evidence also points at rising total trade costs in a model of industry location with endogenous transaction costs that seeks to replicate features from the machinery industry we show how and under which conditions a decline in transport costs can lead to an increase in the total cost of trade the subtle relationship between endogenous transport costs and the sensitivity of trade

capture and ideology in the economic theory of politics the economic theory of regulation long ago put public interest theories of politics to rest these theories have correctly been viewed as normative wishings rather than explanations of real world phenomena they have been replaced by models of political behavior that are consistent with the rest of microeconomics anthony downs 1957 james buchanan and gordon tullock 1965 george stigler 1971 sam peltzman 1976 recently however debate has arisen over whether some version of a public interest theory of regulation will have to be readmitted to our thinking about actions and results in the political arena what is at issue is the empirical importance of the altruistic publicly interested goals of rational actors in determining legislative and regulatory outcomes james kau and paul rubin 1979 kalt 1981 peltzman 1982 this study assesses the nature and significance of publicly interested objectives in a particular instance of economic policymaking u s senate voting on coal strip mining regulations the existence of such objectives is of course no contradiction of the economic view of human behavior kenneth arrow 1972 gary becker 1974 and may well be rooted in genetic biological history becker 1976 jack hirshleifer 1978 generally however individuals altruistic publicly interested goals have been given little attention this reflects the judgment that such goals are so empirically unimportant as to allow the use of occam s razor in positive models or well founded apprehensions that these goals are unusually difficult to identify measure and analyze notwithstanding the latter problem we find that approaches which confine themselves to a view of political actors as narrowly egocentric maximizers explain and predict legislative outcomes poorly the tracking and dissecting of the determinants of voting on coal strip mining policy suggest that the economic theory of politics has been prematurely closed to a broader conception of political behavior

an explanation for why senators from the same state vote differently so frequently abstract this paper explains why rational well informed voters elect politicians with divergent platforms given well defined constituencies and the costliness of any individual politician creating transfers across all interest groups we show that different politicians from the same district can successfully represent vastly different constituencies and still have each politician producing the support maximizing level of transfers our explanation focuses on how obtaining wealth transfers reduces successful constituencies returns to obtaining additional transfers the evidence strongly rejects alternative explanations based upon the median voter and polarized policy preference approaches

political parties and political shirking using ada roll call voting scores for the 1947 2006 period i find that senators shirk in their last term the degree of shirking is limited by political parties which constrain the politician in his last term and varies by post senate career choices the results highlight the importance of political parties in the repeated game that is electoral politics

credit markets in northern nigeria credit as insurance in a rural economy this article addresses the issues of imcomplete markets and imperfect information in the context of credit markets in rural northern nigeria in much recent theoretical literature the problems of moral hazard and adverse selection are assumed to be decisive for the organization of agrarian institutions in contrast it is found that in the four villages surveyed credit transactions take advantage of the free flow of information within rural communities information asymmetries between borrower and lender are unimportant and their institutional consequences the use of collateral and interlinked contracts are absent credit transactions play a direct role in pooling risk between households through the use of contracts in which the repayment owed by the borrower depends on the realization of random production shocks by both the borrower and the lender

immigration and trade creation econometric evidence from canada immigrants may expand trade with their country of origin owing to superior knowledge of or preferential access to market opportunities the authors test this proposition using canadian trade data with 136 partners from 1980 to 1992 in an augmented gravity equation they find that a 10 percent increase in immigrants is associated with a 1 percent increase in canadian exports to the immigrant s home country and a 3 percent increase in imports they also find that among the primary categories of immigrants independents have the greater influence on trade immigration via the entrepreneur class appears to have less impact on trade than all other classes except refugees

storage slow transport and the law of one price theory with evidence from nineteenth century u s corn markets abstract this paper argues that localized price spikes should be a regular feature of competitive commodity markets it develops a rational expectations model of physical arbitrage in which trade takes time and shows that inventory management plays a crucial role in the way regional prices are determined in equilibrium arbitrageurs choose export quantities to ensure inventories in the importing center regularly fall to 0 they earn enough profits from high prices on these occasions to offset small losses at other times an analysis of detailed data from chicago and new york corn markets provides empirical support for the model

marriage laws and growth in sub saharan africa many sub saharan african countries are extremely poor it has been argued that the marriage system in particular polygyny is one contributing factor to the lack of development in this region polygyny leads to low incentives to save depressing the capital stock and output enforcing monogamy might seem like an obvious solution however such a law will have winners and losers in this paper we investigate the transition from a polygynous to a monogamous steady state we find that the initial old men will be big losers the reason is that they had married many wives in anticipation of the brideprice that future daughters will fetch however due to the marriage reform the value of daughters depreciates rapidly as the brideprice changes from positive to negative this increases savings and thereby the aggregate capital stock the interest rate falls and the initial young suffer a loss in capital income thus all men alive during the reform period experience a loss in utility young women and all future generations will benefit however the future gains are not enough to compensate the losers this may explain why many african countries experience strong resistance to changing their marriage laws

gender differentials in farm productivity implications for household efficiency and agricultural policy abstract within many african households agricultural production is simultaneously carried out on many plots controlled by different members of the household detailed plot level agronomic data from burkina faso provides striking evidence of substantial inefficiencies in the allocation of factors of production across the plots controlled by different members of the household production function estimates imply that the value of household output could be increased by 10 15 by reallocating currently used factors of production across plots this finding contradicts standard models of agricultural households a richer model of behaviour which recognizes that the individuals who comprise a household compete as well as co operate has important implications for the structure of agricultural production and for the design of agricultural policy

does electoral accountability affect economic policy choices evidence from gubernatorial term limits this paper analyzes the behavior of u s governors from 1950 to 1986 to investigate a reputation building model of political behavior we argue that differences in the behavior of governors who face a binding term limit and those who are able to run again provides a source of variation in discount rates that can be used to test a political agency model we find evidence that taxes spending and other policy instruments respond to a binding term limit if a democrat is in office the result is a fiscal cycle in term limit states which lowers state income when the term limit binds

male female differences in agricultural productivity methodological issues and empirical evidence abstract most estimates of male female differences in technical efficiency from production function studies show that male and female farmers are equally efficient farm managers controlling for levels of inputs and human capital there is some evidence however of allocative inefficiency within households marginal products of labor depend on the relative scarcities of labor and the gender division of labor in specific farming systems many of these studies however are methodologically flawed greater attention needs to be given to appropriate estimation methods endogenous input choice the use of headship as a stratifying variable and the implications of intrahousehold resource allocation

those who know most insider trading in eighteenth century amsterdam this paper studies how private information is incorporated into prices using a unique setting from the eighteenth century that is closer to stylized models of price discovery than modern day markets specifically the paper looks at english securities traded in both london and amsterdam private information reached amsterdam through sailing boats that sailed only twice a week and in adverse weather could not sail at all results are consistent with a kyle model in which informed agents trade strategically most importantly the speed of information revelation in amsterdam depended on the expected time until the private signal would become public

political accountability and sequential policymaking abstract we develop a model of political accountability with sequential policymaking when a bureaucrat s actions are transparent his overseer faces a political time inconsistency problem she is tempted to revise her retention rule in the middle of the policymaking process as a result the bureaucrat s equilibrium behavior overemphasizes later tasks if the overseer knows the technology by which policies translate into outcomes then she can eliminate these distortions using task specific budget caps however if the overseer is uncertain about this technology such budget caps introduce ex post inefficiency when uncertainty is sufficiently large and consequential the overseer prefers an institutional environment with a fungible budget and no transparency such an environment allows the overseer to exploit the bureaucrat s expertise though at the cost of weaker overall incentives

estimating the effects of the container revolution on world trade many historical accounts have asserted that containerization triggered complementary technological and organizational changes that revolutionized global freight transport we are the first to suggest an identification strategy for estimating the effects of the container revolution on world trade our empirical strategy exploits time and cross sectional variation in countries first adoption of container facilities and combines it with product level variation in containerizability and container usage applying our container variables on a large panel of product level trade flows for the period 1962 1990 our estimates suggest economically large concurrent and cumulative effects of containerization and lend support for the view of containerization being a driver of 20th century economic globalization

the determinants of cross border equity flows abstract we explore a new panel data set on bilateral gross cross border equity flows between 14 countries 1989 1996 we show that a gravity model explains international transactions in financial assets at least as well as goods trade transactions gross transaction flows depend on market size in source and destination country as well as trading costs in which both information and the transaction technology play a role distance proxies some information costs and other variables explicitly represent information transmission an information asymmetry between domestic and foreign investors and the efficiency of transactions the geography of information is the main determinant of the pattern of international transactions while there is weak support in our data for the diversification motive once we control for the informational friction we broaden the scope of our results by presenting some evidence linking the results on equity transactions to equity holdings

brands in motion how frictions shape multinational production following the 2016 leave vote in the referendum on uk membership in the eu and the election of donald trump trade agreements have entered a period of great instability to predict the impact of possible disruptions to existing arrangements requires counterfactual analysis that takes into account the complex set of factors influencing the production and marketing strategies of multinational corporations we estimate a model of multinational decision making in the car industry this model predicts the production reallocation and consumer surplus consequences of changes in tariffs and non tariff barriers induced by nafta termination brexit trans pacific and trans atlantic integration agreements

international trade without ces estimating translog gravity this paper derives a micro founded gravity equation in general equilibrium based on a translog demand system that allows for endogenous markups and substitution patterns across goods in contrast to standard ces based gravity equations trade is more sensitive to trade costs if the exporting country only provides a small share of the destination country s imports as a result trade costs have a heterogeneous impact across country pairs with some trade flows predicted to be zero i test the translog gravity equation and find strong empirical support in its favor

the empirical merit of structural explanations of commodity price volatility review and perspectives this paper presents both the history of and state of the art in empirical modeling approaches to the world commodity price volatility the analysis builds on the storage model and key milestones in its development specifically it is intended to offer a reader unfamiliar with the relevant literature an insight into the modeling issues at stake from both a historical and speculative viewpoint the review considers primarily the empirical techniques designed to assess the merits of the storage theory it does not address purely statistical approaches that do not rely on storage theory and that have been studied in depth in other streams of the commodity price literature the paper concludes with some suggestions for future research to try to resolve some of the existing empirical flaws and hopefully to increase the explanatory power of the storage model

a critical review and an extension of the political shirking literature after substituting actual and real changes for proposed and nominal changes in budgetary and employment levels it is clear that the size and scope of the federal leviathon had not been reduced over 1982 83 it is also clear that the agencies which witnessed real budget cuts over this period were of minor importance in terms of the total u s budget future research on why only small agencies receive real budget cuts will provide us with a better understanding of the budgetary process

on the formation of family structures hitherto models of family economics focus on explaining theorganization of monogamous and polygynous family patterns a thirdexisting marriage pattern polyandrous marriages has beenneglected this paper shows that in contrast to the common view a polyandrous marriage may be individually rational i considera game theoretic model of a subsistence economy whose membersmaximize their personal reproductive success in this model allthree family formations can appear as equilibrium solutions

demand fluctuations in the ready mix concrete industry i investigate the role of demand shocks in the ready mix concrete industry using census data on more than 15 000 plants i estimate a model of investment and entry in oligopolistic markets these estimates are used to simulate the effect of eliminating short term local demand changes a policy of smoothing the volatility of demand has a market expansion effect the model predicts a 39 increase in the number of plants in the industry since bigger markets have both more plants and larger plants a demand smoothing fiscal policy would increase the share of large plants by 20 finally the policy of smoothing demand reduces entry and exit by 25 but has no effect on the rate at which firms change their size

intra national trade costs assaying regional frictions abstract the effects of intra regional inter regional and international frictions on the trade flows of canada s provinces are disentangled by gravity model techniques unexplained trade barriers utbs are the difference between inter provincial trade barriers inferred from pair fixed effects and from bilateral distance and contiguity the estimates reveal large intra national trade costs and utbs that vary significantly across canada s provinces decomposition of utbs into relative border effects and a systematic residual utb is based on a novel cobb douglas aggregator of intra provincial and pure inter provincial trade costs variation of both components across provinces is big

consumption smoothing migration and marriage evidence from rural india a significant proportion of migration in low income countries particularly in rural areas is composed of moves by women for the purpose of marriage we seek to explain these mobility patterns by examining marital arrangements among indian households in particular we hypothesize that the marriage of daughters to locationally distant dispersed yet kinship related households is a manifestation of implicit interhousehold contractual arrangements aimed at mitigating income risks and facilitating consumption smoothing in an environment characterized by information costs and spatially covariant risks analysis of longitudinal south indian village data lends support to the hypothesis marriage cum migration contributes significantly to a reduction in the variability of household food consumption farm households afflicted with more variable profits tend to engage in longer distance marriage cum migration the hypothesized and observed marriage cum migration patterns are in dissonance with standard models of marriage or migration that are concerned primarily with search costs and static income gains

once an enemy forever an enemy the long run impact of the japanese invasion of china from 1937 to 1945 on trade and investment abstract in this study we exploit one of the most important conflicts of the 20th century between what are currently the world s second and third largest economies that is the japanese invasion of china from 1937 to 1945 to investigate the long term impact of conflicts between countries on cross border trade and investment we find that japanese multinationals are less likely to invest in chinese regions that suffered greater civilian casualties during the japanese invasion and these regions also trade less with japan our study shows that historical animosity still influences international trade and investment despite the trend toward an increasingly globalized world

trade tastes and nutrition in india this paper introduces habit formation into an otherwise standard model of international trade household tastes evolve over time to favor foods consumed as a child the opening of trade causes preferred goods to rise in price as these were relatively inexpensive in autarky neglecting the correlation between tastes and agro climatic endowments overstates the short run nutritional gains from agricultural trade liberalization and masks potential caloric losses for laborers i examine the predictions of this model of trade with habit formation using household survey data from india both by looking across indian regions and by examining the consumption patterns of inter state migrants

the value of public information in storable commodity markets application to the soybean market this article provides a framework to estimate the potential effects and benefits of the provision of market information in storable commodity markets this framework is applied to the case of production forecasts for the soybean market a rational expectations storage model of the global soybean market accounting for both inter annual and intra annual market dynamics is built shocks that occur between planting and harvesting affect the size of the potential harvest estimates of the size of these shocks are reported publicly and affect the market equilibrium through adjustments to stock levels by varying counterfactually the observability of seasonal shocks we can estimate the efficiency gains related to the availability of advance information they are equivalent to 2 of storage costs the reduction of stock levels being the main channel explaining the welfare gains the presence of advance information has a limited effect on inter annual price volatility but redistributes price volatility during the season increasing it just before harvest when almost all news has been received and stocks are tight and decreasing it after harvest the effect of news shocks is stronger on higher order moments of the distribution with a strong decrease in skewness and kurtosis related to the lower frequency of price spikes

watta satta bride exchange and women s welfare in rural pakistan in a setting where husbands wield considerable coercive power forms of marriage should adapt to protect the interests of women and their families the authors study the pervasive marriage custom of watta satta in rural pakistan a bride exchange between families coupled with a mutual threat of retaliation they show that watta satta may be a mechanism to coordinate the actions of two sets of in laws each of whom wish to restrain their sons in law but who only have the ability to restrain their sons the authors empirical results support this view the likelihood of marital inefficiency as measured by estrangement domestic abuse and wife s mental health is significantly lower in watta satta arrangements as compared with conventional marriages but only after properly accounting for selection

strategic choices in polygamous households theory and evidence from senegal this paper proposes a strategic framework to account for fertility choices in polygamous households a theoretical model specifies the main drivers of fertility in the african context and describes how the fertility of one wife might impact the behavior of her co wives it generates predictions to test for strategic interactions exploiting original data from a household survey and the demographic and health surveys in senegal empirical tests show that children are strategic complements one wife raises her fertility in response to an increase by the other wife because children are the best claim to resources controlled by the husband this result is the first quantitative evidence of a reproductive rivalry between co wives it suggests that the sustained high level of fertility in africa does not merely reect women s lack of control over births as is often argued but also their incentives to have many children this paper also contributes to the literature on household behavior as one of the few attempts to open the black box of non nuclear families

celestial marriage and earthly rents interests and the prohibition of polygamy abstract just prior to the civil war the u s government set out on a relentless campaign to eliminate polygamy within the mormon church this paper offers evidence that the political restrictions on the practice of polygamy were the result of rent seeking by potential beneficiaries of such laws the edmonds act of 1882 polygamy created benefits for women but reduced the welfare of most men in a time period when only adult males had the franchise

estimating the elderly s returns on the farm evidence from cote d ivoire abstract it is often said that the elderly in rural developing countries are more valued by the members of the society one possible economic reason for the relative status of the elderly in rural areas is that they are likely to have accumulated substantial farm specific capital thus increasing the productivity of the farm this paper examines whether the elderly contribute to the agricultural profits of households in rural cote d ivoire in an uncertain environment we estimate the returns to having elders on the farm using panel data and find that farm specific experience mitigates the fall in profits in adverse environmental conditions particularly at the lower end of the profit distribution thereby contributing to reduce the variance of profits the results hold even after controlling for the level of household assets and household fixed effects and the presence of experienced female members

the erosion of colonial trade linkages after independence high trade between countries with colonial ties may be explained by government policies that establish preferential access or as a consequence of networks formed through social interactions using bilateral trade data from 1948 to 2003 we examine the eect of independence on post colonial trade the severing of formal colonial relations can lead to an immediate reduction in trade as preferential access is eliminated as well as a gradual reduction corresponding to the deterioration of trading networks our results reveal that independence reduces colonial trade with its colonizer metropole the reduction cumulates over a 30 year period and the disruption is particularly severe for hostile separations we also find that overall colonial trade falls subsequent to independence but to a lesser extent than trade with the metropole

a reexamination of the principal agent relationship in politics abstract that senators from the same state often have a large difference in their ideological voting records has proven inconvenient for a literature that has largely relied on a median voter model of elections one exception is palfrey review of economic studies 1984 51 139 156 whose analysis implies the hypothesis that the expected difference in such voting records varies directly with the variance of that state s density function of constituent ideological preferences this paper provides empirical testing consistent with this hypothesis the paper then argues that currently accepted methodology for measuring senatorial shirking is systematically biased towards indicating shirking and provides empirical analysis consistent with this argument

immigration and firms integration in international production networks abstract this paper uses panel data on cross border migration and transaction level trade for swiss municipalities to identify the effect of migration networks on specific margins of the integration of firms in global value chains we find that the stability of an international supplier buyer relationship is strongly associated with a priori knowledge about the supplier s origin as measured by the migrant network with the same country of origin present in the buyer s immediate environment here a municipality not only do firms engage in more stable input trading relationships and intensify relationships in terms of input trading volume but they reduce the total number of suppliers in a given country in response to an increase of immigration from there these results are in line with a theoretical framework where firms sourcing strategies are subject to incomplete information firms diversify their foreign supplier network in order to be less susceptible to potential bad shocks once informational barriers are lifted firms contract fewer suppliers but purchase a larger volume from each of them

the last period problem in politics do congressional representatives not subject to a reelection constraint alter their voting behavior this study of roll call voting behavior in the u s house of representatives empirically documents the existence of an important simultaneity bias in the heretofore much investigated relationship between legislator ideological shirking and the security with which a legislator holds office the results indicate that while greater security allows a policymaker more leeway for ideological consumption increases in ideological on the job consumption also diminish a policymaker s security in office

voting for protection does direct foreign investment influence legislator behavior the political economy of trade protection has long been of interest to economists and policy makers the idea that levels of protection may be endogenous with trade flows has been a particularly important issue in the literature in general the endogenous protection literature postulates that import penetration will cause domestic interests to lobby more intensely for protection thus higher levels of import penetration lead to increased protection as a result a number of papers see for example arye l hillman 1982 wolfgang mayer 1984 robert e baldwin 1985 stephen p magee et al 1989 ronald d fischer 1992 have established that foreign firms will import less under a regime of endogenous protection than one where the level of protection is exogenous to trade flows on the empirical side daniel trefler 1993 finds that ignoring the endogeneity of trade and protection understates the impact of u s protection on imports by a magnitude of ten this abstract was borrowed from another version of this item

time series evidence on shirking in the u s house of representatives this paper presents time series evidence on the voting behavior of members of the u s house of representatives from 1975 to 1990 the empirical results indicate that voting behavior of individual congressmen is remarkably stable over time we find no evidence of economically significant last term effects on voting behavior nor are there important effects of legislative tenure on voting patterns the most significant deviations in voting behavior occur for congressmen who failed to win their reelection bid suggesting that sizable deviations from previous policy positions may result in swift retribution by constituents in the district

intertemporal substitution in labor supply evidence from micro data the sensitivity of the supply of labor to intertemporal variation in the wage is an important issue in macroeconomics the analysis of social security and pensions and the study of life cycle patterns of work this paper explores two approaches to the measurement of intertemporal substitution that have appeared in the literature the first approach is to use consumption to control for wealth and unobserved expectations about future wages in the labor supply equation the second approach is to estimate a first difference equation for hours in which labor supply from the previous period serves as a control for wealth and wage expectations the results indicate that intertemporal substitution elasticity for married men is positive but small

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

collateral damage trade disruption and the economic impact of war abstract conventional wisdom in economic history suggests that conflict between countries can be enormously disruptive of economic activity especially international trade we study the effects of war on bilateral trade with available data extending back to 1870 using the gravity model we estimate the contemporaneous and lagged effects of wars on the trade of belligerent nations and neutrals controlling for other determinants of trade as well as the possible effects of reverse causality we find large and persistent impacts of wars on trade national income and global economic welfare we also conduct a general equilibrium comparative statics exercise that indicates costs associated with lost trade might be at least as large as the conventionally measured direct costs of war such as lost human capital as illustrated by case studies of world wars i and ii

make trade not war this paper analyses theoretically and empirically the relationship between military conflicts and trade we show that the conventional wisdom that trade promotes peace is only partially true even in a model where trade is economically beneficial military conflicts reduce trade and leaders are rational when war can occur because of the presence of asymmetric information the probability of escalation is lower for countries that trade more bilaterally because of the opportunity cost associated with the loss of trade gains however countries more open to global trade have a higher probability of war because multilateral trade openness decreases bilateral dependence to any given country and the cost of a bilateral conflict we test our predictions on a large data set of military conflicts on the 1950 2000 period using different strategies to solve the endogeneity issues including instrumental variables we find robust evidence for the contrasting effects of bilateral and multilateral trade openness for proximate countries we find that trade has had a surprisingly large effect on their probability of military conflict

transportation costs and international trade in the second era of globalization while the precise causes of postwar trade growth are not well understood declines in transport costs top the lists of usual suspects however there is remarkably little systematic evidence documenting the decline this paper brings to bear an eclectic mix of data in order to provide a detailed accounting of the time series pattern of shipping costs the ad valorem impact of ocean shipping costs is not much lower today than in the 1950s with technological advances largely trumped by adverse cost shocks in contrast air shipping costs have dropped an order of magnitude and airborne trade has grown rapidly as a result as a result international trade has also experienced a significant rise in speed

the mystery of monogamy we examine why developed societies are monogamous while rich men through out history have typically practiced polygyny wealth inequality naturally pro duces multiple wives for rich men in a standard model of the marriage market however we demonstrate that higher female inequality in the marriage market reduces polygyny moreover we show that female inequality increases in the process of development as women are valued more for the quality of their chil dren than for the quantity consequently male inequality generates inequality in the number of wives per man in traditional societies but manifests itself as inequality in the quality of wives in developed societies jel j12 j16 j24 z13

product based cultural change is the village global we provide a model of product based cultural change where trade integration leads to cultural convergence a standard trade model of dixit stiglitz monopolistic competition is coupled with a micro founded model of cultural dynamics we show that access to varieties that are attached to a global cultural type changes the incentives of parents to socialize their children and transmit their type the resulting increase in agents of the global cultural type leads to a magnification of the initial shock a striking feature of the model is that even temporary shocks to openness may have permanent effects through the changing distribution of preferences in the economy

does the internet defy the law of gravity abstract we show that gravity holds in the case of digital goods consumed over the internet that have no trading costs therefore trade costs cannot fully account for the effects of distance on trade in particular we show that americans are more likely to visit websites from nearby countries even controlling for language income immigrant stock etc furthermore we show that this effect only holds for taste dependent digital products such as music games and pornography for these a 1 increase in physical distance reduces website visits by 3 25 for non taste dependent products such as software distance has no statistical effect

competitive storage and commodity price dynamics by buying cheap and selling dear risk neutral commodity speculators can smooth commodity prices and induce serial dependence in price even when none would exist under a simple process of supply and demand commodity prices are variable and strongly positively correlated from one year to the next the variability is often explained by supply factors and the autocorrelation by the activities of speculators we show that this explanation is not consistent with the evidence speculation can substantially increase autocorrelation for prices that are weakly autocorrelated in its absence but not to the high levels that are observed in the data

on the timing of marriage cattle and weather shocks abstractin this paper we focus on the timing of marriage of women whose marriages are associated with bride wealth payments these payments concern transfers from the family of the groom to the bride s family unmarried daughters could therefore be considered part of the asset portfolio of the household that at times of need can be cashed we investigate both theoretically and empirically to what extent the timing of marriage of a daughter is affected by the economic conditions of the household from which she originates we distinguish household specific wealth levels and two types of shocks correlated weather shocks and idiosyncratic wealth shocks we estimate a duration model using a unique panel survey of zimbabwean smallholder farmers the estimation results support the hypothesis that the timing of marriage is affected by household characteristics girls from households that experienced a negative idiosyncratic wealth shock are more likely to marry

lifestyles of the rich and polygynous in cote d ivoire abstract this paper investigates whether the sources of income not just the levels determine whether an individual is monogamous our results support the idea that polygyny stunts development by allowing wealthy men to acquire wives rather than investing in child quality

real effects of information frictions when the states and the kingdom became united abstract this paper exploits a unique historical experiment to estimate how information frictions distort international trade the establishment of the transatlantic telegraph in 1866 i use newly collected data on cotton prices trade and information flows from historical newspapers and find that the average and volatility of the transatlantic price difference fell after the telegraph while average trade flows increased and became more volatile using a trade model in which exporters use the latest news about a foreign market to forecast expected prices i estimate the efficiency gains of the telegraph to be equivalent to 8 percent of export value jel d83 f12 f14 l96 n71 n73

the economics of polygyny in sub saharan africa female productivity and the demand for wives in cote d ivoire polygyny is still practiced throughout much of sub saharan africa with important social consequences this paper makes the first attempt to link african polygyny directly to the productivity of women in agriculture using micro data i develop a structural model of the demand for wives that disentangles wealth and substitution effects using a large household survey from cote d ivoire i find that marked geographic diversity in cropping patterns leads to regional variation in female labor productivity i also find that conditional on wealth men do have more wives when women are more productive that is cheaper this substitution effect may explain why polygyny declined in rural areas of cote d ivoire during agricultural development

data watch the world bank s living standards measurement study household surveys since 1985 the world bank has been collecting household survey data in developing countries that provide a rich source of information for assessing household welfare understanding household behavior and evaluating the impact of government policies this article describes these household surveys known as living standards measurement study lsms surveys and explains how to obtain their data lsms surveys have been implemented in over twenty developing countries and have been used to analyze poverty labor markets health and education pricing policies determinants of school performance savings and consumption smoothing health and nutrition policies and gender and fertility issues

migrants ancestors and foreign investments we use 130 years of data on historical migrations to the u s to show a causal effect of the ancestry composition of u s counties on foreign direct investment fdi sent and received by local firms to isolate the causal effect of ancestry on fdi we build a simple reduced form model of migrations migrations from a foreign country to a u s county at a given time depend on 1 a push factor causing emigration from that foreign country to the entire u s and 2 a pull factor causing immigration from all origins into that u s county the interaction between time series variation in origin specific push factors and destination specific pull factors generates quasi random variation in the allocation of migrants across u s counties we find that doubling the number of residents with ancestry from a given foreign country relative to the mean increases the probability that at least one local firm engages in fdi with that country by 4 percentage points we present evidence that this effect is primarily driven by a reduction in information frictions and not by better contract enforcement taste similarities or a convergence in factor endowments

the economics of dowry and brideprice payments between families at the time of marriage existed during the history of most developed countries and are currently pervasive in many areas of the developing world these payments can be substantial enough to affect the welfare of women and a society s distribution of wealth recent estimates document transfers per marriage amounting to six times the annual household income in south asia rao 1993 and four times in sub saharan africa dekker and hoogeveen 2002 this paper first establishes some basic facts about the prevalence and magnitude of marriage payments it then discusses how such patterns vary across countries depending upon economic conditions societal structures institutions and family characteristics such payments have also evolved within societies over time for example in some periods such payments have risen sharply in some cases payments have shifted from the grooms sides to the brides and vice versa also property rights over such payments have sometimes shifted between marrying partners and parental generations economists who have only recently begun to work on the topic have focused on explaining these facts the second part of the paper addresses this economic literature though considerable insight into many of the facts has been gained many of the existing economic explanations are weakly convincing and many puzzles remain one crucial difficulty is that solid data in this field have been extremely rare the descriptions of marriage payments in this paper are synthesized from a patchwork of studies across periods places and even epochs and there are doubtless numerous cases which remain undocumented thus the paper

altruism cooperation and efficiency agricultural production in polygynous households abstractaltruism toward others can inhibit cooperation by increasing the utility players expect to receive in a noncooperative equilibrium to test this we examine agricultural productivity in west african polygynous households we find cooperation as evidenced by more efficient production is greater among co wives than among husbands and wives using a game theoretic model we show that this outcome can arise because co wives are less altruistic toward each other than toward their husbands we present a variety of robustness checks which suggest results are not driven by selection into polygyny greater propensity for cooperation among women or household heads enforcing others cooperative agreements

is risk fully pooled within the household evidence from ghana using detailed household survey data from ghana this paper examines whether the transitory incomes of individual household members affect household expenditure patterns divided into six sections the themes include risk sharing networks household survey data from ghana theoretical framework of risk sharing within households estimating transitory income and effects on household budget shares the conclusion that transitory incomes earned by different members of the household have different effects on household expenditure patterns this implies that household members do not engage in full risk pooling with each other moreover it is not always the case that all women or all men display similar preferences or risk pooling behavior this suggests complex features within the household risk sharing structure which is more complex than might be hypothesized by a simplistic analysis framed along gender lines

the electoral effects of incumbent wealth abstract the absence of limits on own source campaign contributions is widely thought to give wealthy candidates an advantage in congressional elections we employ a unique data set on the wealth of house incumbents running for reelection in 1992 we find that wealthy incumbents do not raise or spend more campaign funds and do not win greater vote shares in their reelection bids further incumbent wealth does not deter high quality challengers

globalization and the dynamics of cultural identity this paper presents a simple model where micro founded dynamics of cultural identity are endogenous and interact with an international trade equilibrium this process generates a strong home bias under autarky we then show that goods market integration causes a phenomenon of cultural divergence whereby the distributions of cultures become more dissimilar across countries and one of the cultures that existed under autarky ultimately disappears by way of contrast we show that social integration causes cultural convergence and can counterbalance the effects of goods market integration

endogenous pricing to market and financing costs abstract this paper explains why relative ppp should hold more tightly in emerging markets and why pricing to market would be observed more frequently in the oecd countries it studies the endogenous determination of pricing to market in a real option model with time dependent transportation costs where the future terms of trade are random allowing time dependent transportation costs adds a dimension of investment to the pre buying of imports implying that financial considerations determine the frequency of pricing to market and the deviations from relative ppp if the expected discounted cost of last minute delivery is higher than pre buying one exercises the option of spot market imports if the realized terms of trade are favorable enough pricing to market is observed in countries characterized by low terms of trade volatility and low financing costs in these circumstances imports are pre bought and the spot market for imports is inactive in countries where the financing costs and the terms of trade volatility are high few imports are pre bought the price of imports is determined by the realized real exchange rate and a version of relative ppp holds with an intermediate level of terms of trade volatility and of financing costs a mixed regime is observed if the realized real exchange rate is weak pricing to market would prevail increasing consumers welfare by shielding them from the adverse purchasing power consequences of weak terms of trade if the realized real exchange rate is favorable enough more imports are purchased in the spot market and the relative ppp would hold higher financing costs increase the cost of pre buying imports reducing thereby the frequency of pricing to market increasing the expected relative price of imports reducing the expected deviations from relative ppp and reducing welfare

demand for insurance and within kin group marriages evidence from a west african country abstract we ask whether parents have incentives to marry their children to a member of the kin group in order to better insure against adverse idiosyncratic income shocks exploiting original panel data from a household survey collected in senegal in 2006 2007 and 2011 2012 we find that daughters within kin group marriage helps their parents household to better smooth food consumption when a parent has fallen ill this better smoothing is notably driven by the fact that households having married a daughter within the kin group receive relatively more transfers our results indicate that parents demand for insurance can explain part of their demand for marrying within the kin group their daughter and extend the literature on inter linkages between marriage decisions and demand for insurance

exposure to foreign media and changes in cultural traits evidence from naming patterns in france abstract free trade in audio visual services has faced opposition on the grounds that foreign media undermine domestic culture and ultimately global diversity using a long panel of french birth registries we assess the media culture link using name frequencies as a measure of tastes controlling for the number of people who currently have a name and unobserved name effects our regressions show that media influences choices via selective imitation parents are much more likely to adopt media names that they associate with youth using estimated parameters we simulate our model of name choice to reveal that absent foreign media fewer than 5 of french babies would have been named differently our simulations also suggest a positive effect of foreign media on the welfare of parents

the risk of polygamy and wives saving behavior in a polygamous society all monogamous women are potentially at risk of polygamy however the anthropological and economic literatures are silent on the potential impact of the risk of polygamy on the economic decisions of monogamous wives this paper explores this issue in senegal using individual panel data the paper first estimates a cox model for the probability of transition to polygamy second it estimates the impact of the predicted risk of polygamy on monogamous wives savings the findings show a positive impact of the risk of polygamy on female savings entrusted to formal or informal institutions which is suggestive of self protective strategies the increase in savings comes at the cost of reduced consumption of household food expenditures and wives private nonfood expenses
