the spot and forward exchange rates some empirical evidence of singapore this paper studies the foreign exchange market of singapore it examines the hypotheses that the spot exchange rate follows a random walk and that the exoected value of the future spot rate is the current forward rate using various powerful tests that have been developed recently in the economietric literature we reject the two hypotheses convincingly

children as collective goods and divorce settlements the failure of many divorced fathers to comply with court mandated child support awards has been identified as a major reason why a growing number of children live in poverty in female headed households this paper presents a model that seeks to explain why so many divorced fathers allow their children s welfare to suffer as a consequence of divorce the point of departure is the recognition that children are collective consumption goods from the point of view of the father and mother within marriage proximity and altruism serve to overcome the free rider problem associated with the provision of public goods however on divorce the noncustodial parent suffers a loss of control over the allocative decisions of the custodial parent and it is not feasible for the couple to achieve a pareto optimal allocation of their joint resources a model of optimal marriage contracts is constructed in which a couple decides on the allocation of resources within marriage and on the terms of a settlement in the event

bequest as a public good within marriage a note bequest to and marriage of children can lead to a pareto inefficient allocation the inefficiency or market failure arises because one family making a bequest to its own child ignores the contribution to the utility of the other family whose child enters the marriage this note shows that an assortative mating rule based on bequests can improve or even restore pareto efficiency when parents take account of the rule in deciding the amount of bequests to their own children

the speculative efficiency hypothesis the hypothesis that forward prices are the best unbiased forecast of future spot prices is often presented in the economic and financial analysis of futures markets this paper considers the hypothesis independently of its implications for rational expectations or market efficiency and in order to stress this fact the term speculative efficiency is used to characterize the state envisaged under the hypothesis if a market is subject to efficient speculation the supply of speculative funds is infinitely elastic at the forward price that is equal to the expected future spot price the expected future spot price is a market price determined as the solution to the underlying rational expectations macroeconomic model although the paper is primarily concerned with testing this hypothesis in the foreign exchange market the methodology introduced in the paper is of general application to all futures markets this abstract was borrowed from another version of this item

one and one half bound dichotomous choice contingent valuation to reduce the potential for response bias on the follow up bid in multiple bound discrete choice cvm questions while maintaining much of the efficiency gains of the multiple bound approach we introduce the one and one half bound oohb approach despite the fact that the oohb model uses less information than the double bound db approach efficiency gains in moving from single bound to oohb capture a large portion of the gain associated with moving from single bound to db in an analysis of survey data our oohb estimates demonstrated higher consistency with respect to the follow up data than the db estimates and were more efficient as well

bequests and the size of population when population is endogenous the consequences of interfamily bequests and endogenous population size for optimal and competitive population sizes and bequests are explored when individuals utility is a function of own consumption the number of children and the welfare of their children when a bequest benefits each member of a second generation family we show that competition leads to underprovision for future generations under a separability assumption the number of children is also shown to be too large

the foreign exchange market in a highly open developing economy the case of singapore abstract the purpose of this paper is to examine the foreign exchange market of singapore from the perspective of market efficiency and further to determine if factors such as the unanticipated changes in interest rate differentials and purchasing power parity play a role in the behavior of the exchange rate using a variety of tests it is shown that the singapore market despite its relatively small size displays many of the same characteristics observed in the markets of developed countries this is taken as a confirmation of the general nature of the empirical regularities found in studies of such markets

on the contingent valuation of mortality risk reduction in developing countries using the contingent valuation method in developing countries to value mortality risk reduction is particularly challenging because of the low level education of the respondents in this article we investigate whether some brief training regarding probability and risk concepts has any significant effect on the willingness to pay wtp responses we elicit individuals risk perceptions by providing information on age specific mortality risks and find that people on average overestimate the mortality risk at younger ages and underestimate it at older ages our results indicate a significantly higher wtp for the trained sub sample and wtp is sensitive to the magnitude of risk reduction for both the sub samples

the rising price of husbands a hedonic analysis of dowry increases in rural india dowries in south asia have steadily risen over the last 40 years and now often amount to over 50 percent of a household s assets this paper attempts to investigate the reasons behind this increase it adapts rosen s implicit market model to the indian marriage market and tests predictions from the model with data from six villages in south central india and from the indian census it is found that a marriage squeeze caused by population growth resulting in larger younger cohorts and hence a surplus of women in the marriage market has played a significant role in the rise in dowries

factors influencing willingness to pay for the energy star label abstract in the united states nearly 17 of greenhouse gas emissions come from residential energy use increases in energy efficiency for the residential sector can generate significant energy savings and emissions reductions consumer labels such as the us environmental protection agency s energy star promote conservation by providing consumers with information on energy usage for household appliances this study examines how the energy star label affects consumer preferences for refrigerators the results of an online survey of a national sample of adults suggest that consumers are on average willing to pay an extra 249 82 349 30 for a refrigerator that has been awarded the energy star label furthermore the results provide evidence that respondent willingness to pay was motivated by both private energy cost savings and public environmental benefits

credit for what informal credit as a coping strategy of market women in northern ghana abstract this paper explores the use of informal credit as a strategy for managing risks by market women in northern ghana a broad concept of the costs of risk management strategies is introduced and encompasses both a time and monetary dimension based on qualitative data the analysis reveals that market women invest a considerable amount of time in maintaining complex networks of informal credit providers to ensure their access to credit once a shock occurs informal credit involves high transaction costs and prevents market women from growing out of poverty in the long term

the effect of marital endowments on domestic violence in india abstract numerous studies have documented a relationship between income and wealth of a woman and domestic violence one such factor that could potentially impact domestic violence is the gold endowment a woman receives at the time of marriage india presents a unique setting in which to test this relationship as despite being unlawful both dowry practices and domestic violence continue to prevail as actual marital endowments may endogenously affect spousal match quality i use the deviation of the price of gold at the time of marriage from its long term trend as a source of exogenous variation to proxy for initial marital endowment and examine its effect on domestic violence results show a positive and significant effect of an unusually high price of gold at the time of marriage on domestic violence

the public s value for developing ocean energy technology in the republic of korea a contingent valuation study abstract ocean energy is a type of renewable energies and is considered as having a potential power of providing a substantial amount of energy although some forms of ocean energy are developed there is a need for further technological advances to better utilize ocean energy government should take observable actions to compensate for the costs of developing the technology this paper attempts to apply a contingent valuation cv method to obtaining at least a preliminary evaluation of the benefits that ensue from the development of the technology that commercializes ocean energy in the republic of korea overall the cv survey was successfully carried out to elicit the willingness to pay wtp for ocean energy the wtp was statistically significantly estimated from one and one half bounded spike model and the monthly mean wtp estimates was krw 1003 usd 0 9 per household the estimates of the annual benefits to relevant residents amounted to krw 206 4 billion usd 183 8 million

collective labor supply and welfare the paper develops a general collective model of household labor supply in which agents are characterized by their own possibly altruistic preferences and household decisions are only assumed to be pareto efficient an alternative interpretation is that there are two stages in the internal decision process agents first share nonlabor income according to some given sharing rule then each one optimally chooses his or her own labor supply and consumption this setting is shown to generate testable restrictions on labor supplies moreover the observation of labor supply behavior is sufficient for recovering individual preferences and the sharing rule up to a constant finally the traditional tools of welfare analysis can be adapted to the new setting

spike models in contingent valuation spike models allow for a nonzero probability of zero willingness to pay in referendum style contingent valuation experiments they include many of the often used models as special cases and allow various analyses that are not possible in standard applications in this paper the economic rationale for the spike models and their estimation techniques are discussed and empirical illustrations are provided one study suggests that mean willingness to pay is zero and both studies strongly suggest that median wtp is zero these results have some bearing on the continuing debate of the incentive properties of hypothetical surveys and the construction of scenarios in contingent valuation experiments

flexible exchange rates prices and the role of news lessons from the 1970s recent experience with flexible exchange rate systems has led to renewed interest in the operation of foreign exchange markets as reflected in many recent studies of the principal determinants of exchange rates the 1970s witnessed the dramatic alteration of the international monetary system from a regime of pegged exchange rates which prevailed for about a quarter of a century since the bretton woods conference into a regime of flexible though managed rates as a consequence of the emergence of the new legal and economic system traders national governments and international organisations were confronted with new economic problems choices and instruments during the 1970s ex change rates fluctuated widely and inflation rates accelerated the international monetary system had to accommodate extraordinarily large oil related shocks which affected trade flows in goods and assets huge oil payments had to be recycled uncertainties concerning future developments in international politics reached new heights and the prospects for the world economy got gloomier these developments placed unprecedented pressures on the markets for foreign exchange as well as on other asset markets they were associated with a large slide in the value of the us dollar and resulted in speeding up the creation of new institutions like the european monetary system which provided the formal framework for the management of exchange rates among members

marital transfer and intra household allocation a nash bargaining analysis this paper explores the implications of inter generational marital transfers on the allocation of resources within a conjugal household adopting a nash bargaining framework with alternative models of the threat points it is argued that parents have greater incentive to make transfers to a married child than to a single child because of the efficiency gains from joint consumption and production of family public goods and because of the increase in bargaining power of the child in the allocation of private consumption such transfers also enhance marital stability by increasing the efficiency gains from marriage

a fresh look at the rotten kid theorem and other household mysteries gary becker s rotten kid theorem asserts that if all family members receive gifts of money income from a benevolent household member then even if the household head does not precommit to an incentive plan for family members it will be in the interest of selfish family members to maximize total family income i show by examples that the rotten kid theorem is not true without assuming transferable utility i find a simple condition on utility functions that is necessary and sufficient for there to be the kind of transferable utility needed for a rotten kid theorem while restrictive these conditions still allow one to apply the strong conclusions of the rotten kid theorem in an interesting class of examples

efficient estimation methods for closed ended contingent valuation surveys closed ended contingent valuation surveys can be very useful in the evaluation of nonmarket resources respondents merely state whether they would accept or reject a hypothetical threshold amount either as payment for giving up access to the resource or as a fee for its use the authors develop a maximum likelihood procedure which exploits the variation in the threshold values to allow direct and separate point estimates of regression like slope coefficients and error standard deviations without truncation bias their illustration uses data from a survey of recreational fisherman to examine factors which influence individuals willingness to pay copyright 1987 by mit press

expenditure decisions of divorced mothers and income composition in this paper we analyze the relationship between the income sources of custodial divorced parents and their expenditure patterns we use data from the consumer expenditure survey to directly investigate the issue of whether or not divorced mothers receiving child support income spend larger amounts on child goods than those not receiving child support holding total household income constant by comparing the estimated coefficients on child support income and other income in an endogenous engel curve specification we argue that we can classify child goods as being public or private and say something about the expenditure patterns of noncustodial fathers under a nash equilibrium model of parental expenditures on public child goods and some plausible assumptions regarding the manner in which child support transfer decisions are made by noncustodial fathers our empirical results indicate that income composition does affect the expenditure patterns of divorced mothers and that consumption externalities exist even among divorced parents

dowry and wife s welfare a theotrical and empirical analysis becker attributes the existence of marital transfers to inflexibility in the division of joint product within the marriage if that were the only reason we would not have observed the coexistence of dowries and bride prices this paper offers an alternative analysis while becker s interpretation is retained for bride prices a dowry is now represented as a premortem bequest by altruistic parents for a daughter it not only increases the wealth of the new conjugal household but also enhances the bargaining power of the bride in the allocation of the output within the household thereby safeguarding here welfare using micro data from taiwan we found that a dowry improves the bride s welfare whereas a bride price has no effect these empirical results support the theoretical predictions of the model

marriage markets and assortative mating with household public goods theoretical results and empirical implications this paper analyzes marriage market equilibria when the gains from marriage result from joint consumption of household public goods assuming transferable utility within marriage the paper proves that marriage markets will be characterized by positive assortative mating on wealth when spouses differ only in endowments and the gains to marriage result only from public goods when spouses differ in wages and household public goods are produced at home the results imply offsetting effects with public good economies creating an incentive for positive assortative mating on wages and gains from specialization creating an incentive for negative assortative mating on wages the results help explain the persistent lack of empirical support for becker s prediction of negative assortative mating on wages and have implications for empirical analysis of all joint living arrangement decisions

contingent valuation and social choice the contingent valuation method for estimating the existence value of natural resources is examined for psychophysical robustness statistical reliability and economic sensibility extensions of standard models for willingness to pay and suitable econometric techniques for analyzing these models are developed the analysis is applied to a series of experiments on the value of preserving wilderness areas in the western united states the results call into question the reliability of the cv method for estimating existence values

independence of allocative efficiency from distribution in the theory of public goods when is the pareto optimal amount of public goods independent of income distribution subject to some regularity conditions the answer is when preferences of every individual i can be represented by a utility function of the form u x i y a y x i b i y where x i is i s consumption of private goods and y is the amount of public goods

separate spheres bargaining and the marriage market this paper introduces the separate spheres bargaining model a new model of distribution within marriage it differs from divorce threat bargaining models e g manser brown mcelroy horney in that the threat point is not divorce but a noncooperative equilibrium within marriage this noncooperative equilibrium reflects traditional gender roles the predictions of our model thus differ from those of divorce threat bargaining models in the separate spheres model cash transfer payments to the mother and payments to the father can but need not imply different equilibrium distributions in existing marriages in the long run the distributional effects of transfer policies may be substantially altered by changes in the marriage market equilibrium

property rights over marital transfers in developing countries the extent to which women possess property rights is shaped in large part by transfers received at the time of marriage focusing on dowry we develop a simple model of the marriage market with intra household bargaining in order to understand the incentives for brides parents to allocate the rights over the dowry between their daughter and her groom in doing so we clarify and formalize the dual role of dowry as a pre mortem bequest and as a market clearing price identified in the literature we use the model to shed light on the intriguing observation that in contrast to other rights women s rights over the dowry tend to deteriorate with development we show how marriage payments are utilized even when they are inefficient and how the marriage market mitigates changes in other dimensions of women s rights even to the point where women are worse off following a strengthening of such rights we also generate predictions for when marital transfers will disappear and highlight the importance of female human capital for the welfare of women

income and outcomes a structural model of intrahousehold allocation there is evidence from several sources that one cannot treat many person households as a single decision maker if this is the case then factors such as the relative incomes of the household members may affect the final allocation decisions made by the household we develop a method of identifying how incomes affect outcomes given conventional family expenditure data the basic assumption we make is that household decision processes lead to efficient outcomes we apply our method to a sample of canadian couples with no children we find that the final allocations of expenditures on each partner depend significantly on their relative incomes and ages and on the level of lifetime wealth
