women and budget deficits if women have different economic preferences than men then female economic and political empowerment is likely to change economic policy and in turn perhaps macroeconomic outcomes in this paper we narrow the focus to fiscal policy and we investigate whether female enfranchisement affects government budget deficits in a difference in differences regression for swiss cantonal panel data we find that the inclusion of women in the electorate has reduced deficits by a statistically significant amount

mexico and the brady plan mexico has throughout the 1980s been centre stage in the debates and events shaping the sovereign debt problem caught between a sudden collapse of its terms of trade and rising world interest rates mexico suspended debt service payments in august 1982 and ushered in what has since become known as the debt crisis in the following years lending to ldcs dried up and debtor countries were increasingly forced to run high trade surpluses to effect ever growing transfers from poor back to rich countries in the face of falling growth rates and rising inflation in the high debt countries then secretary of the treasury baker proposed the baker plan in return for economic reforms high debt countries would get new access to medium term new loans in addition to rolling over of amortization of old loans new loans had to come both from commercial creditors and the official lending institutions with access to capital markets restored the economic reforms would it was hoped allow the debtors to grow out of debt but experience in the high debt countries showed that the original hopes of the proponents of the baker plan went unfulfilled net transfers out of the borrowing countries went up rather than down as

consumption and children abstract consumption by couples rises sharply in the beginning and falls later in life the causes of the early rise are hotly contested among the suggestions are rule of thumb behavior demographics liquidity constraints the precautionary motive and nonseparabilities between consumption and labor supply we develop two tests of the extreme hypothesis that only changes in family structure matter we estimate effects of the numbers and ages of children on consumption these estimates allow us to rationalize all of the increase in consumption without recourse to any of the causal mechanisms our estimates can be interpreted either as giving upper bounds on the effects of children or as evidence that the other causes are not important

rational household labor supply traditionally household behavior is derived from the maximization of a unique utility function in this paper we propose an alternative approach in which the household is modeled as a two member collectivity taking pareto efficient decisions the consequences of this assumption are analyzed in a three good model in which only total consumption and each member s labor supply are observable if the agents are assumed egoistic i e they are only concerned with their own leisure and consumption it is possible to derive falsifiable conditions upon household labor supplies from both a parametric and nonparametric viewpoint if alternatively agents are altruistic restrictions obtain in the nonparametric context useful interpretation stems from the comparison with the characterization of aggregate demand for a private good economy

grading minimum quality standards and the labeling of genetically modified products we relate the labeling of genetically modified gm products to the theory of grading and minimum quality standards the model represents three stages in the supply chain assumes a vertical product differentiation framework allows for the accidental commingling of non gm products and treats regulation as a purity threshold for non gm products we find that a non gm purity level that is too strict leads to the disappearance of the non gm product and that some quality standard benefits farmers indeed the standard that is optimal from the perspective of producers is stricter than what is optimal for consumers and for societal welfare

consumption effects of genetic modification what if consumers are right this paper develops a model of differentiated consumers to examine the consumption effects of genetic modification gm under alternative labelling regimes and segregation enforcement scenarios analytical results show that if consumers perceive gm products as being different than their traditional counterparts gm affects consumer welfare and thus consumption decisions when the existence of market imperfections in one or more stages of the supply chain prevents the transmission of cost savings associated with the new technology to consumers gm results in welfare losses for consumers the analysis shows that the relative welfare ranking of the no labelling and mandatory labelling regimes depends on i the level of consumer aversion to gm products ii the size of marketing and segregation costs under mandatory labelling iii the share of the gm product in total production and iv the extent to which gm products are incorrectly labelled as non gm products

the risk of divorce and household saving behavior we analyze the causal impact of an increase in the risk of marital dissolution on the saving behavior of married couples we use the legalization of divorce in ireland in 1996 as an exogenous shock to the risk of divorce we propose several comparison groups unaffected by the law change that allow us to use a difference in differences approach our findings suggest that the legalization of divorce led to a significant increase in the propensity to save by married individuals which is consistent with individuals saving more as a response to the increase in the probability of marital breakup

asset allocation and asset location household evidence from the survey of consumer finances abstract the rapid growth of assets in self directed tax deferred retirement accounts has generated a new set of financial decisions for many households in addition to deciding which assets to hold the traditional choice among bonds stocks and other investment classes households with substantial assets in both taxable and tax deferred accounts tda must now decide where to hold them this paper uses data from the survey of consumer finances to assess how many households have enough assets in both taxable and tax deferred accounts to face significant asset location choices it also investigates the asset location decisions these households make in 2001 49 of households had at least some assets in a tax deferred account and more than 11 million households had at least us 25 000 in both a taxable and a tax deferred account asset allocation inside and outside tax deferred accounts is quite similar with about 70 of assets in each location invested in equity securities roughly two thirds of households with financial assets in both taxable and tax deferred accounts hold portfolios that are tax efficient most of the other third could reduce their taxes by relocating heavily taxed fixed income assets to their tax deferred account for more than half of the households that hold apparently tax inefficient portfolios however a shift of less than us 10 000 in financial assets would eliminate tax inefficiency

tax planning of married couples and intra household income inequality abstract this paper examines tax planning of married couples under separate taxation it shows that concerns about the intra household income distribution prevent couples from minimizing tax payments the empirical analysis exploits a specific feature of the german tax system which allows married couples to save taxes by deviating from the default symmetric payroll tax treatment and assigning favorable tax treatment to the primary earner and unfavorable tax treatment to the secondary earner based on a representative random sample of individual tax files we find that a couple is less likely to choose the tax minimizing treatment if tax planning is associated with a larger decline of the net of tax income of the secondary earner this applies regardless of whether the husband or the wife is the main earner however couples where the wife is the main earner are generally more reluctant to assign the more favorable tax treatment to the wife

individual versus joint taxation in models with household production in a recent paper piggott and whalley 1996 challenge the conventional wisdom that says that the individual rather than the household should be the unit of taxation and argue instead for joint taxation their point of departure is a point well taken the literature on which this wisdom is based in particular boskin and sheshinski 1983 ignores the existence of household production the general argument is a nice one in the theory of the second best in the absence of taxation of market wage income the marginal rates of technical substitution between primary and secondary labor in market and in household production would be equal to each other and the marginal rate of substitution between the market and household good would be equal to the marginal rate of transformation between them thus achieving pareto efficiency introduction of income taxation leads to a distortion of the relation between the marginal rate of substitution and the marginal rate of transformation which is the focus of concern in the literature 2 and given the differing econo

wealth and portfolio composition theory and evidence we examine a survey of 6010 u s households and estimate a model for household portfolio allocation we extend the conventional portfolio choice model in order to capture the observed incompleteness of household portfolios we show that the empirical specification of the joint discrete and continuous choice that characterizes household portfolio behavior is a switching regressions model with endogenous switching we go on to examine the impact of taxes on portfolio composition using detailed survey data to calculate precisely the marginal tax rate facing each household finally we estimate wealth elasticities of demand for a range of assets and liabilities

trade gmos and environmental risk are current policies likely to improve welfare food with inputs from genetically modified organisms gmos has met considerable skepticism among european union eu consumers the eu import ban on gm food has triggered a great deal of controversy and has been partly replaced by a mandatory labeling scheme although there is no measure in the general agreement on tariffs and trade that directly addresses the use of product labeling wto and others have been skeptical to mandatory product labeling on the grounds that they may be used as hidden protectionism hampering global welfare this study has two foci first we examine how different policies for the production and use of gmos might influence the market outcome in consumer food markets second we evaluate the welfare effects of the policy measures we find that mandatory labeling often increases domestic welfare and may also enhance global welfare on the other hand a trade ban is more likely to decrease global welfare

social motives vs social influence an experiment on interdependent time preferences we report experimental evidence on the effects of social preferences on intertemporal decisions to this aim we design an intertemporal dictator game to test whether dictators modify their discounting behavior when their own decision is imposed on their matched recipients we run four different treatments to identify the effect of payoffs externalities from those related to information and beliefs our descriptive statistics show that heterogeneous social time preferences and information about others time preferences are significant determinants of choices dictators display a marked propensity to account for the intertemporal preferences of recipients both in the presence of externalities social motives and or when they know about the decisions of their matched partners social influence we also perform a structural estimation exercise to control for heterogeneity in risk attitudes as for individual behavior our estimates confirm previous studies in that high risk aversion is associated with low discounting as for social behavior we find that social motives outweigh social influence especially when we restrict our sample to pairs of dictators and recipients who satisfy minimal consistency conditions

innovation and trade with endogenous market failure the case of genetically modified products a partial equilibrium two country model is developed to analyze implications from the introduction of genetically modified gm products in the model innovators hold proprietary rights farmers are competitive adopters some consumers deem gm food to be inferior in quality to traditional food and the mere introduction of gm crops affects the costs of non gm food because of costly identity preservation among the results derived it is shown that although gm innovations have the potential to improve efficiency some groups can be made worse off indeed it is even possible that the costs induced by gm innovations outweigh the efficiency gains

mexico stabilization debt and growth mexico rudiger dornbusch mexico today is at a crossroads as the de la madrid presidency which has been dominated by the debt crisis comes to an end a number of major policy difficulties remain inflation is still a problem and the continuation of stagnation in a country where the population grows by 3 a year is clearly unsustainable the outlook for inflation is dependent on the government s ability to keep its budget under control the stabilization programme has been quite successful in this respect but the cost in terms of foregone growth is staggering the issue here is how to collect the disinflation benefits of policy restraint analysing the peculiar process of rapid inflation both in mexico and elsewhere the author calls for an incomes policy as for growth it is closely linked to the external situation mexico which triggered the debt crisis in 1982 has made remarkable progress in achieving a non interest current account surplus yet its external debt remains huge and requires a continuation of net transfers abroad the experience though is that debt service comes at the expense of productive investment and growth the author proposes to escape from the unacceptable choice between debt service and growth by adopting what he calls interest rescheduling a debt equity swap applied to interest payments rather than to the principal

who pays the costs of non gmo segregation and identity preservation our aim is to explore who pays the costs and who reaps the benefits of maintaining a dual market system of genetically modified organisms gmos and non gmos we analyze the welfare effects of the introduction of consumer hatred given gmo technology and the introduction of gmo technology given hatred making alternative assumptions of competitive and then monopolistic supply we recognize that identity preservation ip of non gmos creates costs for ip and non ip producers we model these costs as depending on the sizes of the two supply channels copyright 2003 oxford university press

two crises inflationary inertia and credibility this paper provides a comparative analysis of the mexican currency crisis of 1994 and the chilean crisis of 1982 to assess to what extent exchange rate based stabilisation programmes are successful in reducing or even eliminating inflationary inertia the paper provides a brief overview of the chilean and mexican reform and stabilisation programmes a theoretical model that emphasises the role of credibility is developed to analyse the effects of exchange rate based stabilisation programmes on inflationary inertia according to the model less than credible stabilisations will not eliminate inertia and will generate major real exchange rate overvaluation detailed data are used to test the hypothesis

genetically modified crops and product differentiation trade and welfare effects in the soybean complex a partial equilibrium four region world trade model for the soybean complex is developed in which roundup ready rr products are weakly inferior substitutes to conventional ones rr seeds are priced at a premium and costly segregation is necessary to separate conventional and biotech products solution of the calibrated model illustrates how incomplete adoption of rr technology arises in equilibrium the united states argentina brazil and the rest of the world row all gain from the introduction of rr soybeans although some groups may lose the impacts of rr production or import bans by the row or brazil are analyzed u s price support helps u s farmers despite hurting the united states and has the potential to improve world efficiency

valuing product innovation genetically engineered varieties in us corn and soybeans we develop a discrete choice model of differentiated products for us corn and soybean seed demand to study the welfare impact of genetically engineered ge crop varieties using a unique data set spanning the period 1996 2011 we find that the welfare impact of the ge innovation is significant in the last five years of the period analyzed our preferred counterfactual indicates that total surplus due to ge traits was 5 18 billion per year with seed manufacturers appropriating 56 of this surplus the seed industry obtained more surplus from ge corn whereas farmers received more surplus from ge soybeans

differential income taxation and household asset allocation this article empirically investigates the effects of differential income taxation on households portfolio choice and asset allocation applying a two stage budgeting model of asset demand to german survey data the model is structured into the discrete and the continuous asset choice cross sectional variation in marginal tax rates appropriately instrumented as well as over time variation from a major tax reform are used to identify the tax effects households with higher tax rates are found to have relatively greater demand for tax privileged assets such as nonowner occupied housing mortgage repayments building society deposits stocks insurances and consumer credits than households with lower tax rates demand at higher tax rates is lower for owner occupied housing bank deposits and bonds

stockholding behavior of u s households evidence from the 1983 1989 survey of consumer finances most households persistently invest in riskless assets but not stocks and may do so because they perceive information required for market participation to be costly relative to expected benefits in a consumption capital asset pricing model ccapm increased risk aversion income risk and lower resources reduce the information expense sufficient to deter stockholding bivariate probit analysis using the 1983 1989 survey of consumer finances shows that households with lower risk aversion higher education and greater wealth who were nonstockholders in 1983 had an increased conditional probability of entering by 1989 whereas 1983 stockholders with lower resources more limited education and greater risk aversion were more likely to be nonstockholders by 1989

does the balance of power within a family matter the case of the retirement equity act abstract this paper studies within family decision making regarding investment in income protection for surviving spouses using a simple and tractable nash bargaining model a change in us pension law the retirement equity act of 1984 is used as an instrument to derive predictions from the bargaining model about the household demand for survivor annuities and life insurance and to contrast these with the predictions of the classical single utility function model of the household in the empirical part of the paper the predictions of the classical model are rejected in favor of the predictions of the nash bargaining model

on the proportionality of eu spatial ex ante coexistence regulations reply desquilbet and bullock 2010 criticize some aspects of our analysis of the european union s eu spatial ex ante coexistence regulations seacers of genetically modified gm and non gm crops presented in demont et al 2009 we argue that besides misinterpreting some of our original arguments the authors propose a policy analysis framework which is inconsistent with the main goal of the eu s seacers their example incorrectly suggests that seacers play an additional role of regulating non gm crop supply on the market this would be inefficient from a policy economics perspective especially in an open economy where global trade is taken into account therefore we argue that analyzing flexibility of seacers in a market framework could lead to erroneous conclusions and in that case a simple farm level analysis such as presented in demont et al 2009 is preferred

the retirement consumption puzzle a marital bargaining approach abstract evidence from several countries reveals a substantial drop in household consumption around the age of retirement that is difficult to explain with life cycle models using food consumption data from more than 550 households from the panel study of income dynamics for the years 1979 1986 and 1989 1992 we find that married couple households decrease their expenditures on both food consumed at home and away from home by about 9 following the retirement of the male household head no significant decrease in consumption is found for single households either in a sample of males or a pooled sample of single males and females these results are consistent with a model of marital bargaining in which wives prefer to save more than their husbands do to support an expected longer retirement period and relative control over household decisions is affected by control over market income the pattern of the consumption decline which is increasing in the age gap between husband and wife lends further support to this interpretation

an econometric analysis of income tax evasion and its detection this article presents an econometric analysis of income tax evasion and its detection based on individual level data drawn from the internal revenue service 1982 and 1985 taxpayer compliance measurement programs i specify a model consisting of two equations the first measures the extent of evasion the second the fraction of evasion detected the empirical analysis explores the effects of income the marginal tax rate and various socioeconomic characteristics on filer evasion behavior and it assesses the variability in detection rates among irs examiners finally i use the empirical estimates to construct new estimates of the income tax gap the new estimates are very close to the previous irs estimates

intellectual property rights and the welfare effects of agricultural r d the profound changes that have affected agriculture in modern times are perhaps best illustrated by the evolution of production techniques due to mechanization new chemical inputs such as herbicides pesticides and fertilizers genetic selection of crops and animals new crop varieties and countless other technical and organizational improvements these innovations have allowed a generalized increase in physical output while at the same time agriculture has suffered a massive exodus of labor forces towards the non farm sectors indeed a stylized fact of developed countries post war growth is that productivity in agriculture has grown faster than in other sectors jorgenson and gollop 1992 this remarkable record naturally begs the question of what is at its root and a view that commands considerable consensus is that agricultural productivity growth is due to past investments in scientific research and development r d

the saving behaviour of a two person household the facts that wives are typically younger than their husbands and that women typically live longer than men imply that wives may have more incentive to save for old age than do husbands a theoretical model of the determination of household saving and portfolio choice is introduced which takes into account differences in preferences for saving the most important result is that the level and the composition portfolio of saving and the time path of consumption are dependent on the distribution of income within the household women typically live longer than men and wives are typically younger than their husbands these two facts imply that preferences about saving for old age in married households with forward looking members may differ between husband and wife this paper presents a theoretical analysis of saving and portfolio behaviour if the members of the household have differ ent preferences over future consumption as compared to current consump tion the analysis stands in contrast to unitary models of household intertemporal allocation which assume that the household has a single utility function thus this paper is a contribution in a novel context to the burgeoning literature on intra household decision making the base case analysis is for a simple two person husband and wife1 two period model in which there is only one asset saving it is assumed that because of the two facts given at the start of the introductory paragraph the husband discounts the future more than the wife in section ii the implications of a non cooperative decision making process for the base case are derived see ulph 1988 for a non cooperative model of demand and

mexico s investment collapse debt or oil abstract this paper tests three explanations for mexico s investment collapse in the early 1980s the oil price decline the termination of capital inflows and debt overhang uncertainty effects using previously ignored investment data on private sector industries the data consistently point to the importance of the rise in the relative price of investment goods driven in large part by falling world oil prices but the data also allow a role for the termination of capital inflows however after controlling for these effects the paper finds little evidence for debt overhang effects heightened uncertainty or other commonly cited explanations in the literature jel f34

economic crisis adjustment and living standards in mexico 1982 85 abstract this paper presents an estimate of the impact of economic crisis and adjustment on the living standards of the mexican population between 1982 and 1985 the analysis is based on information on wage and nonwage incomes unemployment functional income distribution changes in public expenditures and social indicators the specific questions addressed are what happened to agricultural and nonagricultural wage and nonwage incomes how did unemployment and the composition of employment change what was the impact of fiscal cuts on social expenditures and food subsidies were social services affected by declining resources did social indicators worsen in addition households strategies in response to declining incomes are briefly discussed finally conjectures are made regarding which population groups were hurt most by the crisis the results indicate that the crisis and adjustment process left mexico with a relatively impoverished middle class and with rising poverty

the effects of marital status and children on savings and portfolio choice this paper investigates the impact of demographic shocks on optimal decisions about saving life insurance and most centrally asset allocation we analyze these choices within the framework of a life cycle model that features exogenous changes in family composition heterogeneity in lifetime income and uninsurable fluctuations in earnings and medical costs our analysis indicates that marital status transitions and children can have important effects on optimal household decisions widowhood induces sharp reductions in the portfolio shares in stock and the impact is largest for women and individuals with children divorce causes men and women to reallocate their portfolios in different directions men choose much riskier allocations while women opt for safer ones children play a fundamental role in the optimal portfolio decisions men with children for example increase their shares in response to divorce by less than half as much as men without children comparing our simulation results with panel data evidence on stockholding from the psid and the hrs we conclude that changes in marital status and children matter empirically as well but not always in the ways that the model predicts

saving risk sharing and preferences for risk saving decisions are made jointly by household members who generally earn risky incomes consequently to interpret saving patterns it is crucial to analyze the relationship between intrahousehold risk sharing and intertemporal choices to that end in this paper the household is characterized as a group of agents with possibly heterogeneous preferences making efficient decisions two results are obtained first it is shown that risk sharing can increase the amount saved by the household second i find that an increase in risk aversion and prudence of an individual member can reduce household risk aversion and prudence these results are consistent with the empirical evidence collected using the hrs

taxation and household portfolio composition us evidence from the 1980s and 1990s abstract this paper explores the relationship between household marginal income tax rates the set of financial assets that households own and the portfolio shares accounted for by each of these assets it analyzes data from the 1983 1989 1992 1995 and 1998 surveys of consumer finances and develops a new algorithm for imputing federal marginal tax rates to households in these surveys the empirical findings suggest that marginal tax rates have important effects on asset allocation decisions the probability that a household owns tax advantaged assets such as tax exempt bonds or assets held in tax deferred accounts is positively related to its tax rate on ordinary income in addition the portfolio share invested in corporate stock which is taxed less heavily than interest bearing assets is increasing in the household s ordinary income tax rate holdings of heavily taxed assets such as interest bearing accounts decline as a share of wealth as a household s marginal tax rate increases

monetary and exchange rate arrangements for nafta abstract this paper considers the extent to which the north american free trade area nafta meets the criteria for a common currency area nafta is compared with the ec a regional grouping for which initial plans for a monetary union are already in place most of the anticipated benefits from a monetary union in the ec apply with equal force to nafta however because the underlying disturbances are more diverse across members of nafta the costs of abandoning the exchange rate instrument are likely to be higher this is particularly true when nafta is compared to the ec s continental core

life insurance and household consumption abstract using life insurance holdings by age sex and marital status we infer how individuals value consumption in different demographic stages we estimate equivalence scales and bequest motives simultaneously within a fully specified model where agents face us demographics and save and purchase life insurance our findings indicate that individuals are very caring for dependents that economies of scale are large that children are very costly or yield very high marginal utility that wives with children produce lots of home goods and that females display habits from marriage while men do not these findings contrast sharply with standard equivalence scales

income splitting among the self employed under individual taxation with progressive marginal tax rates households in which the distribution of income is unequal benefit from attributing income to the lower income household member self employment provides greater potential to split income in this way because of the absence of a third party reporting income using the canadian experience as a case study this paper develops a unique estimator of the incidence of illegal income splitting among self employed couples the results suggest that the incidence of income splitting among self employed men in canada is non trivial but no evidence is found that self employed women attribute income to their spouses jel classification h26 h21 h31 j22 le fractionnement du revenu chez les travailleurs autonomes dans un regime fiscal qui a des taux marginaux d imposition progressive des revenus les membres d un menage dans lequel la repartition des revenus n est pas g rien n indique que les femmes qui sont travailleurs autonomes attribuent une portion de leurs revenus a leur epoux

personal taxation pension wealth and portfolio composition this paper emphasizes the roles played by personal taxation and pension wealth in portfolio choice and composition a theoretical discussion of the impacts of taxation and participation in social security and private pension systems on individual wealth allocation is followed by empirical evidence based on u s cross section data both effects prove to be significant anticipated social security and private pension benefits exert a measurable influence on household portfolio allocation their omission from an asset demand model may lead to a misinterpretation of the impact of taxation on portfolio composition

static and intertemporal household decisions we discuss the most popular static and dynamic models of household behavior our main objective is to explain which aspects of household decisions different models can account for using this insight we describe testable implications identification results and estimation findings obtained in the literature particular attention is given to the ability of different models to answer various types of policy questions

pareto optimal trade in an uncertain world gmos and the precautionary principle optimal trade policy in an uncertain world is examined decision maker attitudes toward uncertainty are represented in terms of the gilboa schmeidler 1989 maximin expected utility mmeu model the central result is that in a two country general equilibrium setting with both trading partners possessing an mmeu preference structure pareto optimality can require one trading partner to absorb all uncertainty in the economy if its set of priors is a subset of its trading partners an immediate corollary is that autarky is pareto optimal if the trading partner with the more inclusive set of priors either chooses or is endowed with a nonstochastic technology

yours mine and ours do divorce laws affect the intertemporal behavior of married couples divorce laws establish spouses individual property rights over household resources and determine when divorce is allowed this paper examines how such laws inuence the intertemporal behavior and the welfare of u s married couples i build a model of household choice about consumption labor supply and divorce under multiple divorce law regimes and i estimate it using exogenous variation in u s divorce laws from the 1970s to the 1990s couples responded to equal division of property and unilateral divorce by increasing tangible assets up to 19 which suggests the presence of a strong income eect for the primary earner and by reducing female employment by over 5 percentage points because the threat of divorce granted additional bargaining power to married woman the bargaining weight of women implied by these responses in the model corresponds to a third of the weight of men this indicates that equal division of assets beneted women when it was

pharmaceutical and industrial traits in genetically modified crops coexistence with conventional agriculture this paper discusses the implications of using genetically modified crops to biomanufacture pharmaceuticals and industrial compounds from the perspective of their co existence with conventional agriculture such plant made pharmaceuticals and plant made industrial products rely on exciting scientific and technological breakthroughs and promise new opportunities for the agricultural sector but they also entail novel risks the management of the externalities and of the possible unintended economic effects that arise in this context is critical and poses difficult questions for regulators

taxation and the household abstract previous analyses of demand systems and the welfare effects of taxing male and female labour supplies suppress the analysis of household resource allocation by assuming a household utility function to analyse the implications of assuming this is not the case we construct a simple but fairly general model of household resource allocation and use the properties of the equilibrium of this model to characterise the effects of tax policy on individual utilities as determined by the household resource allocation process

the effect of gender based returns to borrowing on intra household resource allocation in rural bangladesh summary income from rural microcredit borrowing can empower women and consequently lead to investments in children s education and health this article examines the effect of male and female self employment returns to borrowing in rural bangladesh on intra household resource allocation and decision making abilities and how these effects differ with different borrowing sources household expenditure patterns measure intra household allocation the results show that female borrowers are better able to allocate their income toward goods more valuable to them and make major household decisions when their income increases this serves as evidence of increased empowerment or bargaining power of rural women in bangladesh

the nature of the farm abstract using a model based on a trade off between moral hazard incentives and gains from specialization this paper explains why farming has generally not converted from small family based firms into large factory style corporate firms nature is both seasonal and random and the interplay of these qualities generates moral hazard limits the gains from specialization and causes timing problems between stages of production by identifying conditions in which these forces vary we derive testable predictions about the choice of organization and the extent of farm integration to test these predictions we study the historical development of several agricultural industries and analyze data from a sample of over 1 000 farms in british columbia and louisiana in general seasonality and randomness so limit the benefits of specialization that family farms are optimal but when farmers are successful in mitigating the effects of seasonality and random shocks to output farm organizations gravitate toward fa

new evidence on taxes and portfolio choice abstract identifying the effect of differential taxation on portfolio allocation requires exogenous variation in marginal tax rates marginal tax rates vary with income but income surely affects portfolio choice directly in systems of individual taxation like canada s couples with the same household income can face different effective tax rates on capital income when labor income is distributed differently within households using this source of variation we find portfolio responses to taxation among more affluent households the estimated effects are statistically significant but economically modest in a placebo test using data from the u s which has joint taxation we find no effect of the intra household distribution of labor income on portfolios

collective household models principles and main results in the traditional approach to consumer behaviour it is assumed that households behave as if they were single decision making units this approach has methodological empirical and welfare economic deficiencies a valuable alternative to the traditional model is the collective approach to household behaviour the collective approach explicitly takes account of the fact that multi person households consist of several members which may have different preferences among these household members an intrahousehold bargaining process is assumed to take place in addition to providing an introduction to the collective approach this survey intends to show how different collective household models each with their own aims and assumptions are connected

off farm work decisions of farm couples and land transfer choices in rural china although previous studies have widely examined the association between off farm work participation and land use behaviours of rural households little attention has been paid to the effects of the

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

for richer for poorer assortative mating and savings preferences do couples share the same values the social sciences have mainly concentrated on comparing the socioeconomic characteristics of spouses but rarely consider their attitudes to risk and time in this paper we use conventional measurements and an original method of scoring we find that spouses are very similar in their savings preferences even when we control for the individual characteristics our results suggest that most of this relationship comes from marital sorting these conclusions are decisive in explaining the decision process within households and its implications for wealth inequalities between households since homogamy causes a divide in the population

efficient intra household allocations a general characterization and empirical tests the neoclassical theory of demand applies to individuals yet in empirical work it is usually taken as valid for households with many members this paper explores what the theory of individuals implies for households that have more than one member we make minimal assumptions about how the individual members of the household resolve conflicts all we assume is that however decisions are made outcomes are efficient we refer to this as the collective setting we show that in the collective setting household demands must satisfy a symmetry and rank condition on the slutsky matrix we also present some further results on the effects on demands of variables that do not modify preferences but that do affect how decisions are made we apply our theory to a series of surveys of household expenditures from canada the tests of the usual symmetry conditions are rejected for two person households but not for one person households we also show that income pooling is rejected for two person households we then test for our collective setting conditions on the couples data none of the collective setting restrictions are rejected we conclude that the collective setting is a plausible and tractable next step to take in the analysis of household behavior

spousal control and intra household decision making an experimental study in the philippines i elicit causal effects of spousal observability and communication on financial choices of married individuals in the philippines when choices are private men put money into their personal accounts when choices are observable men commit money to consumption for their own benefit when required to communicate men put money into their wives account these strong treatment effects on men but not women appear related more to control than to gender men whose wives control household savings respond more strongly to the treat ment and women whose husbands control savings exhibit the same response changes in information and communication interact with underlying control to produce mutable gender specific outcomes

present bias and collective dynamic choice in the lab we study collective decisions by time discounting individuals choosing a common consumption stream we show that with any heterogeneity in time preferences utilitarian aggregation necessitates a present bias in lab experiments three quarters of social planners exhibited present biases and less than two percent were time consistent roughly a third of subjects acted as if they were pure utilitarians and the rest chose as if they also had varying degrees of distributional concerns

taxation and the portfolio structure of spanish households using a sample of 5962 spanish households from the survey of household finances eff undertaken by the bank of spain this article describes the structure of their portfolio and estimates both a probit model and a tobit model to test how taxation affects respectively the decision to invest in each asset and the relative importance of each asset within the household portfolio the influence of taxation is measured using the average marginal personal income tax rate of the household the estimations performed show that the marginal tax rate is significant and displays the sign expected to explain both the holding of tax favourable assets and their weight in the household portfolio

on the economics of labels how their introduction affects the functioning of markets and the welfare of all participants are labels good or bad for consumers and firms the answer may seem straightforward since labels improve information yet economic theory reveals situations where their introduction reduces the welfare of at least some market participants this essay reviews the theoretical literature on labels in order to identify and explain the main reasons that may cause labeling to produce undesirable side effects in contrast to earlier reviews that either concentrate on narrow topics or treat the subject in a more or less informal way we bring together the main results from all the relevant topics by presenting and discussing the assumptions and model building techniques that underpin them the advantage of this approach is that it identifies the origin of the differences between results thus allowing the synthesis of results that sometimes appear even to be contradictory we focus on quality labels and examine the impact of labeling on market structure the side effects of costly certification issues related to the label s trustworthiness the rationale for mandatory vs voluntary labeling the level at which the label s standard is set according to the agency that selects it the political economy of labels that is pro or anti label lobbying lobbying to affect the label s standard and lobbying in favor or against the label s mandatory imposition these topics cover a wide range of applications including genetically modified organism gmos organic produce geographic indicators controlled origin eco labels etc we conclude by identifying topics that require further research

debt relief growth and price stability in mexico inspired by the negotiation of the foreign debt of mexico in 1989 this paper provides a framework to show that prior to debt relief an ldc government which is indebted both domestically and externally has an additional incentive not to default on its external obligations however repayment of the external debt is shown to involve a delicate tradeoff between growth and inflation on the one hand the government increases its ability to keep domestic interest rates relatively low thereby promoting investment and growth on the other hand the government worsens the budget deficit problem thereby introducing additional inflationary pressures the way to improve this tradeoff is by negotiating a debt relief operation on the foreign debt

should i stay or should i go an econometric analysis of retirement decisions by couples abstractthis article analyses retirement decisions from a household perspective treating the retirement timing of spouses as potentially interdependent choices to identify the determinants of ret

the effects of joint taxation of married couples on labor supply and non wage income abstract the united states changed its tax treatment of married couples in 1948 from a system in which each spouse paid taxes on his or her own income to a system in which a married couple is taxed as a unit the switch from separate to joint taxation changed incentives for labor supply and asset ownership this paper investigates the effects of the conversion to joint taxation taking advantage of a natural experiment created by cross state variation in property laws married individuals in states with community property laws had always been taxed as if each spouse had earned half of the couple s income and thus were unaffected by the 1948 legal change comparing the behavior of highly educated taxpayers in affected and unaffected states indicates that the tax change is associated with a decline of approximately 2 percentage points in the employment rate of married women consistent with the higher first dollar tax rates they faced after 1948 women married to self employed men were also less likely to have non wage income after 1948 reflecting pre 1948 allocation of family assets to wives for tax purposes the effects of joint taxation on married men s labor force participation and non wage income holding are generally not statistically significant

redistribution of individual pension wealth to survivor pensions evidence from a stated preferences analysis abstract pension schemes in the netherlands allow workers to redistribute their own pension wealth to increase the survivor pension of their partner however due to lacking communication and knowledge of survivor pensions among workers and also due to the lack of transparent products and choice architecture redistribution remains limited this paper uses a stated preferences experiment that is explicitly designed for workers with a partner in the age group of 55 to 65 years to elicit their pension redistribution preferences we find that on average the preferred pension wealth redistribution amounts to 50 35 of all individuals have such a preference 33 of all individuals would prefer less redistribution and 32 percent prefers to redistribute more pension income to the partner upon one s death we further show that total family income during working life does not affect the redistribution to survivor pensions however the distribution of the contribution to total family income before retirement across partners as well as the survival likelihood of the partner and the number of years the partner is expected to survive have a significant causal impact on the preferred pension redistribution decision the preference for redistribution to survivor pensions also depends significantly on personal characteristics preferences and social attitude males have a significantly stronger preference for redistribution compared to females moreover forward looking more risk averse and more altruistic individuals have a stronger preference to redistribute part of their pension wealth to a survivor pension finally in particular when employees have the perception that their partner is more forward looking they are willing to invest more in a survivor pension

intra household resource allocation an inferential approach if household income is pooled and then allocated to maximize welfare then income under the control of mothers and fathers should have the same impact on demand with survey data on family health and nutrition in brazil the equality of parental income effects is rejected unearned income in the hands of a mother has a bigger effect on her family s health than income under the control of a father for child survival probabilities the effect is almost twenty times bigger the common preference or neoclassical model of the household is rejected if unearned income is measured with error and income is pooled then the ratio of maternal to paternal income effects should be the same equality of the ratios cannot be rejected there is also evidence for gender preference mothers prefer to devote resources to improving the nutritional status of their daughters fathers to sons

intra family distribution of paid work time this article analyses the intra family distribution of paid work time in five european countries france germany italy spain and the uk to that end we formulate a collective model which allows us to characterize the efficient labour supply decisions of each spouse this two equation model is then simultaneously estimated by using national panel data drawn from the european community household panel echp 1994 2001 empirical results clearly show that in all sample countries the labour supply of wives is affected by own wages household and own nonlabour incomes and the number of children whereas evidence for husbands differs across countries

market and welfare effects of second generation consumer oriented gm products we examine the economic effects of the introduction of consumer oriented genetically modified gm products into the food system by developing a model of heterogeneous consumers and producers that allows for vertical and horizontal differentiation between the products available to consumers the model facilitates the estimation of consumer and producer surpluses in the product utility and product net returns spaces results show that the introduction of consumer oriented gm products can change the relationship between gm and conventional and organic products from one of vertical to one of horizontal product differentiation and can enhance both economic welfare and the market acceptance and growth of agricultural biotechnology

ethics welfare and markets an economic analysis the present article examines society s welfare when goods with identical physical attributes can be produced using two alternative technologies one of them less ethically desirable but less expensive for at least some producers for the scenario where identification costs must be borne by producers and consumers of the high quality good the outcome under unregulated markets is identical to the optimal solution of a central planner constrained to neither ban the undesirable technology nor segregate the low quality good however under certain circumstances the unregulated market equilibrium may be improved upon by government intervention that shifts the burden of identification costs to the producers of the low quality good or which bans the production of the low quality good the optimal intervention needs to be determined case by case and depends on consumer preferences relative production costs and relative costs of identification and fraud prevention

the impact of separate taxation on the intra household allocation of assets evidence from the uk abstract the income tax system in the united kingdom moved from joint to independent taxation of husbands and wives income in 1990 one interesting aspect of independent taxation is the ability for households to choose the division of household assets between the two spouses this tax reform therefore creates an opportunity for households to engage in a form of tax avoidance by shifting their investment income to the spouse with the lower marginal tax rate we use family expenditure survey fes data to examine the impact of this tax reform on the magnitude of investment income shifting between spouses with different marginal tax rates we find a sizeable shift in the share and incidence of asset income claimed by wives who typically have lower marginal tax rates as well as in the incidence of the wife claiming all the household asset income indicating that households responded to this policy change by reallocating asset ownership

incomplete adoption of a superior innovation we consider a model in which an innovating monopolist of a technologically superior intermediate input must sell this product to final output producers prior research shows that with complete information the monopolist s optimal strategy will lead to complete adoption of this technologically superior innovation in this article we show that when the price of some competitively supplied input used in the final product market is endogenous and is altered by adoption of the innovation then the optimal pricing strategy of the monopolist may lead to incomplete innovation thus the standard result of complete adoption of the superior technology is partly attributable to the partial equilibrium nature of prior models

gmo standards endogenous policy and the market for information the paper develops a composite index of gmo standards restrictiveness for 60 countries assigning objective scores to six different regulatory dimensions using this index and its components we empirically investigate the political and economic determinants of gmo regulations for 55 countries controlling for spatial autocorrelation results show that many of the determinants highlighted in the theoretical literature such as the structure of the agricultural sector and the institutional environment are important determinants of the restrictiveness of the gmo regulation as a key result there emerges a prominent role of the market for information showing that the structure of domestic mass media public vs private is an important driver of gmo standards

genetically modified crops their market and welfare impacts a framework is developed for examining price and welfare effects of the introduction of genetically modified gm products in the short run non gm grain generally becomes another identity preserved product however more profound market effects are observed under some reasonable parameterizations when calibrated to reflect the u s corn market introducing gm technology increases aggregate welfare over a wide range of scenarios unless the corresponding production cost savings are small and consumers are seriously concerned about gm products the possibility that gm technology may reduce aggregate welfare is interesting because the model assumes rational agents and does not include regulatory constraints

family policy with non cooperative families we consider a non cooperative model of a family s time allocation between market work and providing a home produced family public good such as child care or care for the elderly the model predicts underprovision of the public good because of crowding out this does not necessarily warrant public provision in contrast to other approaches in family economics we find that attempts to redistribute between spouses may alter the final distribution within the marriage and that such a policy may be pareto improving we also find that some degree of progressivity of the income tax can be welfare improving

optimal dynamic tax evasion a portfolio approach abstract most tax evasion models are set in a timeless environment though this is not suitable for a study of revenues from financial activities where tax evasion occurs in a dynamic environment this study examines a representative agent aiming to maximize the expected utility from inter temporal consumption and could invest in both riskless and risky assets through tax evasion is possible only in the latter case the investor must pay a fine when his her evasion is detected with a given probability we show that i optimal consumption is higher with tax evasion ii optimal evasion is affected by neither the return nor the volatility of the risky asset iii evasion reduces investment in the risky asset and increases investment in the riskless asset iv evasion can be reduced more efficiently by increasing the fine rather than by increasing the frequency of controls v for a sufficiently high tax rate on the riskless asset the optimal evasion is zero and vi if the fine is proportional to the amount of taxes for only sufficiently low fines the yitzhaki 1974 paradox is confirmed

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

labeling regulations and segregation of first and second generation genetically modified products innovation incentives and welfare effects we review some of the most significant issues and results on the economic effects of genetically modified gm product innovation with emphasis on the question of gm labeling and the need for costly segregation and identity preservation activities the analysis is organized around an explicit model that can accommodate the features of both first generation and second generation gm products the model accounts for the proprietary nature of gm innovations and for the critical role of consumer preferences vis a vis gm products as well as for the impacts of segregation and identity preservation and the effects of a mandatory gm labeling regulation we also investigate briefly a novel question in this setting the choice of research direction when both cost reducing and quality enhancing gm innovations are feasible

agricultural biotechnology the promise and prospects of genetically modified crops for millennia humans have modified plant genes in order to develop crops best suited for food fiber feed and energy production the earliest efforts far predating gregor mendel s 19th century discoveries on trait inheritance involved the selective breeding of plants with desirable characteristics but the recombination of dna in offspring was random consequently plant breeding often took decades and frequently yielded crop varieties with unforeseen and undesirable properties today conventional plant breeding remains inherently random and slow constrained by the availability of desirable traits in closely related plant species in contrast agricultural biotechnology employs the modern tools of genetic engineering to reduce uncertainty and breeding time and to transfer traits from more distantly related plants arguments in support of and in opposition to the use of genetically engineered seeds have changed little since the technology emerged in the 1980s on one side critics express concerns that the technology imposes negative environmental effects and jeopardizes the health of those who consume the frankenfoods on the other side supporters emphasize potential gains from boosting output and lowering food prices for consumers they argue that such gains are achieved contemporaneous with the adoption of farming practices that lower agrochemical use and lessen soil

did tax flattening affect rrsp contributions in 1988 marginal personal income tax rates changed in canada for some individuals by reasonably substantial amounts in this note a large sample of tax filer data is examined and the conclusion is drawn that when attention is paid to the possible confounding of marginal tax rate and non linear income effects there is no convincing evidence that the tax rate changes affected contributions to registered retirement saving plans rrsps est ce que l aplatissement des taux d imposition influence les contributions au reer en 1988 les taux marginaux d imposition du revenu personnel ont change au canada et pour certaines personnes ces changements ont ete substantiels cette note examine un grand echantillon de rapports d impots et en arrive a la conclusion que quand on prend en compte le melange possible des effets du taux marginal d imposition et des effets de revenu non lineaires il n y a pas de resultats qui montrent de facon probante que les changements dans les taux d imposition ont influence les contributions au reer

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
