welfare economics risk and uncertainty social decisions in risky contexts raise a number of difficult questions such as 1 should social decisions be more or less risk averse than the average person 2 should we try to avoid large catastrophes more than frequent but limited harms with similar expected impact 3 should social decisions be ambiguity averse or stick to the expected utility canon this paper reviews the welfare economics of risk and uncertainty and examines possible answers to these questions based on the pros and cons of utilitarianism ex ante egalitarianism and ex post egalitarianism

efficient and durable decision rules with incomplete information we compare six concepts of efficiency for economies with incomplete information depending on the stage at which individuals welfare is evaluated and on whether incentive constraints are recognized an example is shown in which an incentive efficient decision rule may be unanimously rejected by the individuals in the economy we define durable decision rules which can resist such unanimous rejection and show that efficient durable decision rules exist

are contributions of time and money substitutes or complements abstractthis article empirically investigates the relationship between donations of time and money using canadian tax policy reforms that changed the tax price of charitable donations the 1988 reform where a charitable tax deduction was converted to a credit and the 2000 reform in provincial income taxes provide tax price variations plausibly exogenous to individuals unobserved heterogeneity our estimates on cross price effects imply that individuals make more time donations as the tax price of charitable donations increases and hence money and time donations are substitutes as some theories would imply this contrasts with earlier findings using cross sectional data

contractual arrangement and marketing practices in the indirect export channel the association between contractual arrangement and the marketing practices of export intermediaries and domestic supplies is examined based on data collected from a national sample of export management companies the effect of structuring the export arrangement as a contractual administrative or conventional channel is analyzed prior research suggests that contractual form establishes the framework within which all the economic and sociopolitical interactions between the supplier and export middleman take place hypothesized relationship between export practices and channel structure are empirically tested and the central role of structure in the operation of export channels is largely confirmed

on the indifference relation in bewley preferences abstract bewley s 2002 influential model of preferences over uncertain prospects features an incomplete preference relation and a set of priors over the states of the world such that one act is preferred to another if and only if its expected utility is higher under every prior in that set this note shows that under general conditions on preferences the decision maker in the bewley model cannot be indifferent between distinct monetary acts whenever the set of priors is fully dimensional in the special case of two states in particular such objectively rational preferences are incomplete if and only if the indifference relation is trivial in the above sense

utilitarian aggregation of beliefs and tastes harsanyi s utilitarianism is extended here to savage s framework we formulate a pareto condition that implies that both society s utility function and its probability measure are linear combinations of those of the individuals an indiscriminate pareto condition has been shown to contradict linear aggregation of beliefs and tastes we argue that such a condition is not compelling society should not necessarily endorse a unanimous choice when it is based on contradictory beliefs our pareto condition is restricted to choices that involve identical beliefs only

demand for charity donations in private non profit markets the case of the u k abstract this paper presents estimates of the demand for donations for u k charities in 1985 these estimates make demand depend upon price fund raising expenditure a quality index and alternative revenue sources the price elasticity of donations found here shows for the most part an elastic response and is consistent with previous studies using u s data our empirical results suggest that non profits in the u k unlike their counterparts in the u s are net revenue maximisers we discovered no significant evidence that public donations crowded out private donations in our sample of 300 charities

no betting pareto dominance we argue that the notion of pareto dominance is not as compelling in the presence of uncertainty as it is under certainty in particular voluntary trade based on differences in tastes is commonly accepted as desirable because tastes cannot be wrong by contrast voluntary trade based on incompatible beliefs may indicate that at least one agent entertains mistaken beliefs we propose and characterize a weaker no betting notion of pareto domination which requires on top of unanimity of preference the existence of shared beliefs that can rationalize such preference for each agent

fair management of social risk we provide a general method for extending social preferences defined for riskless economic environments to the context of risk and uncertainty we apply the method to the problems of managing unemployment allowances in the context of macroeconomic fluctuations and catastrophic risks in the context of climate change the method guarantees ex post fairness and pays attention to individuals risk attitudes while ensuring rationality properties for social preferences revisiting basic ideas from harsanyi s celebrated aggregation theorem harsanyi 1955 the social preferences that we obtain do not always take the form of an expected utility criterion but they always satisfy statewise dominance when we require social preferences to be expected utilities we obtain a variant of harsanyi s result under a weak version of the pareto principle and a maximin criterion under a stronger pareto requirement whenever the ex post social ordering does not depend on people s risk attitudes we also show how non expected utility individual preferences can be accommodated in the approach

robust social decisions we propose and operationalize normative principles to guide social decisions when individuals potentially have imprecise and heterogeneous beliefs in addition to conflicting tastes or interests to do so we adapt the standard pareto principle to those preference comparisons that are robust to belief imprecision and characterize social preferences that respect this robust principle we also characterize a suitable restriction of this principle the former principle provides stronger guidance when it can be satisfied when it cannot the latter always provides minimal guidance

uncertainty and risk in financial markets this paper considers a general equilibrium model in which the distinction between uncertainty and risk is formalized by assuming agents have incomplete preferences over statecontingent consumption bundles as in bewley 1986 without completeness individual decision making depends on a set of probability distributions over the state space a bundle is preferred to another if and only if it has larger expected utility for all probabilities in this set when preferences are complete this set is a singleton and the model reduces to standard expected utility in this setting we characterize pareto optima and equilibria and show that the presence of uncertainty generates robust indeterminacies in equilibrium prices and allocations for any specification of initial endowments we derive comparative statics results linking the degree of uncertainty with changes in equilibria despite the presence of robust indeterminacies we show that equilibrium prices and allocations vary continuously with underlying fundamentals equilibria in a standard risk economy are thus robust to adding small degrees of uncertainty finally we give conditions under which some assets are not traded due to uncertainty aversion

climate change policy what do the models tell us very little a plethora of integrated assessment models iams have been constructed and used to estimate the social cost of carbon scc and evaluate alternative abatement policies these models have crucial flaws that make them close to useless as tools for policy analysis certain inputs e g the discount rate are arbitrary but have huge effects on the scc estimates the models produce the models descriptions of the impact of climate change are completely ad hoc with no theoretical or empirical foundation and the models can tell us nothing about the most important driver of the scc the possibility of a catastrophic climate outcome iam based analyses of climate policy create a perception of knowledge and precision but that perception is illusory and misleading jel c51 q54 q58

why do people volunteer an experimental analysis of preferences for time donations why do individuals volunteer their time even when recipients receive far less value than the donor s opportunity cost previous models of altruism that focus on the overall impact of a gift cannot rationalize this behavior despite its prevalence we develop a model that allows for differential warm glow depending on the form of the donation in a series of laboratory experiments that control for other aspects of volunteering such as its signaling value subjects demonstrate behavior consistent with the theoretical assumption that gifts of time produce greater utility than the same transfers in the form of money subjects perform an effort task accruing earnings at potentially different wage rates for themselves or a charity of their choice with the ability to transfer any of their personal earnings to charity at the end of the experiment subjects exhibit strong preferences for donating time even when differential wage rates make it costly to do so the results provide new insights on the nature of vo

ex ante and ex post welfare optimality under uncertainty it is widely believed by economic theorists that if there were no transactions costs and if all information about the economy were perfectly shared by all then arrow debreu contingent commodity markets should bring about an ideal allocation the basis for this belief seems clear we have the two efficiency theorems of welfare economics which assure us that in the absence of external effects any competitive allocation is pareto efficient and that any pareto efficient allocation is competitive provided that appropriate lump sum transfers are made of course there are some reservations that need to be made local satiation and non convexities are well known to cause problems but these are not the problems i wish to discuss here to return to the usual argument the next step involves noticing how with contingent commodity markets the efficiency theorems of welfare economics carry over to an economy with uncertainty as explained for instance in chapter 7 of debreu s theorpj of value the fundamental value judgment that gives these efficiency theorems their normative interest is what may be called consumer sovereignty it is an assumption that the social welfare ordering should respect the preferences that govern consumers market behaviour it is a serious value judgment more serious than most economists have been prepared to concede but its seriousness increases when there is uncertainty we know full well that individuals misperceive the probabilities of certain events assuming that they even perceive any probabilities at all see for example kahneman and tversky 1979 nor are we always willing to accept as appropriate the attitudes to risk of individuals who seem either extremely reckless or extremely cautious societies are often willing to make some gestures towards property owners who have not insured themselves adequately against damage from fire flood or tempest and not just because of imperfect insurance markets or even misperceptions of probabilities in addition the inequalities of income that arise when some individuals take more risks than others are not necessarily seen to be desirable particularly if an individual has undertaken a useful but risky activity and has a very low income as a result of failure such gestures are examples of contingent lump sum transfers it seems clear that if such transfers occur to a sufficient extent they could supplant completely the securities markets which are usually sufficient to bring about pareto efficiency they may even be able to go further and correct the imperfections of an arrow debreu market allocation when individuals do misperceive probabilities or else have wrong attitudes to risk this is the main question i wish to consider here the idea that consumer sovereignty should not always extend to economies with uncertainty is not new it can be found in work by diamond 1967 dr6ze

compensating differentials and self selection an application to lawyers this paper models individual choice between two types of jobs as dependent on the difference in potential earnings and on preferences for nonpecuniary the model leads to simultaneous estimation of earnings and job choice functions in a manner that takes account of self selection of individuals into the sector of highest utility an application to lawyers choosing between private and public interest law casts doubt on the notion that public interest lawyers are accepting substantially lower earnings by virtue of their choice an impression derived from estimation of earnings functions without accounting for self selection the estimation technique also takes proper account of the choice based nature of the sample which appears to be important

preference aggregation with incomplete information we show in an environment of incomplete information that monotonicity and the pareto property applied only when there is common knowledge of pareto dominance imply i there must exist a common prior over the smallest common knowledge event and ii aggregation must be ex ante and ex post utilitarian with respect to that common prior and individual von neumann morgenstern utility indices

effects of financial innovations on market volatility when beliefs are heterogeneous abstract consider a model with two logarithmic utility maximizer agents that observe aggregate consumption but disagree about its expected rate of change markets are incomplete we first show that volatility of the interest rate in an economy with additional information is higher in a complete markets economy with no additional information there are two differences in volatility with the previous the first one due to the increase in volatility of the wealth share of the individuals is always positive the second difference is the change in covariance between the components of the interest rate volatility and can be positive or negative

belief disagreements and collateral constraints belief disagreements have been suggested as a major contributing factor to the recent subprime mortgage crisis this paper theoretically evaluates this hypothesis i assume that optimists have limited wealth and take on leverage so as to take positions in line with their beliefs to have a significant effect on asset prices they need to borrow from traders with pessimistic beliefs using loans collateralized by the asset itself since pessimists do not value the collateral as much as optimists do they are reluctant to lend which provides an endogenous constraint on optimists ability to borrow and to influence asset prices i demonstrate that the tightness of this constraint depends on the nature of belief disagreements optimism concerning the probability of downside states has no or little effect on asset prices because these types of optimism are disciplined by this constraint instead optimism concerning the relative probability of upside states could have significant effects on asset prices this asymmetric disciplining effect is robust to allowing for short selling because pessimists that borrow the asset face a similar endogenous constraint these results emphasize that what investors disagree about matters for asset prices to a greater extent than the level of disagreements when richer contracts are available relatively complex contracts that resemble some of the recent financial innovations in the mortgage market endogenously emerge to facilitate betting

indecisiveness undesirability and overload revealed through rational choice deferral three reasons why decision makers may defer choice are indecisiveness between various feasible options unattractiveness of these options and choice overload this paper provides a choice theoretic explanation for each of these phenomena by means of three deferral permitting models of decision making that are driven by preference incompleteness undesirability and complexity constraints respectively these models feature rational choice deferral in the sense that whenever the individual does not defer he chooses a most preferred feasible option as a result choices are always consistent with the weak axiom of revealed preference the three models suggest novel ways in which observable data can be used to recover preferences as well as their indecisiveness desirability and complexity components or thresholds several examples illustrate the relevance of these models in empirical and theoretical applications

is everything neutral in his well known analysis of the national debt robert barro introduced the notion of a dynastic family this notion has since become a standard research tool particularly in the areas of public finance and macroeconomics in this paper we critique the assumptions on which the dynastic model is predicated and argue that this framework is not a suitable abstraction in contexts in which the objective is to analyze the effects of public policies we reach this conclusion by formally considering a world in which each generation consists of a large number of distinct individuals as opposed to one representative individual we point out that family linkages form complex networks in which each individual may belong to many dynastic groupings the resulting proliferation of linkages between families gives rise to a host of neutrality results including the irrelevance of all public redistributions distortionary taxes and prices since these results are not at all descriptive of the real world we conclude

does it pay for women to volunteer this article estimates the economic and noneconomic returns to volunteering for prime aged women estimates of a dcdp model indicate that an extra year of volunteer experience increases wage offers by 8 5 in future part time work and by 2 6 in future full time work on average working for free increases lifetime earnings by 16 7 the economic returns to volunteering are more important than the noneconomic returns in increasing lifetime utility the model also reveals an adverse selection mechanism into volunteering that helps explain why reduced form regressions of the returns to working for free will likely be downward biased

leverage cycles and the anxious economy ing opportunities for emerging economies their access to international markets has turned out to be very volatile with frequent periods of market closures even worse as we will show emerging economies with sound fundamentals are the ones that issue less debt during these closures the goal of this paper is to present a theory of asset pricing that will shed light on the problems of emerging assets like emerging markets that are not yet mature enough to be attractive to the general public their marginal buyers are liquidity constrained investors with small wealth relative to the whole economy who are also marginal buyers of other risky assets we will use our theory to argue that the periodic problems faced by emerging asset classes are sometimes symptoms of what we call a global anxious economy rather than of their own fundamental weaknesses

a welfare criterion for models with distorted beliefs this paper proposes a welfare criterion for economies in which agents have heterogeneously distorted beliefs instead of taking a stand on whose belief is correct our criterion asserts an allocation to be belief neutral ine cient if it is ine cient under any convex combination of agents beliefs while this criterion gives an incomplete ranking of social allocations it can identify negative sum speculation in a broad range of prominent models with distorted beliefs

how giving affects giving a long term analysis of donations social preferences theories suggest that at least some people show altruistic behaviour however this philanthropic behaviour ranges from pure altruistic preferences to reluctant altruists the fa

resource dependency and institutional theory perspectives on direct and indirect export choices this article develops and tests resource dependency and institutional theory arguments to explain two choices facing sme owner managers 1 the decision whether to export or not and 2 if the firm exports the choice between a direct to customers abroad and an indirect using another firm as intermediary export mode binomial logistic regressions on our sample of 871 dutch smes suggest that institutional theory perspectives owner managers perception of the increased international presence of their domestic competitors customers and suppliers and perceptions of increased use of foreign suppliers explain the decision to export while resource dependency theory arguments owner managers perception of the favorability of access to knowledge and technology of production costs and of access to capital in the home market guide the choice between direct and indirect export modes

trade with heterogeneous prior beliefs and asymmetric information no trade theorems have shown that new information will not lead to trade when agents share the same prior beliefs this paper explores the structure of no trade theorems with heterogeneous prior beliefs it is shown how different notions of efficiency under asymmetric information ex ante interim ex post are related to agents prior beliefs as well as incentive compatible and public versions of those efficiency concepts these efficiency results are used to characterize necessary and sufficient conditions on agents beliefs for no trade theorems in different trading environments

pareto optimal redistribution and private charity abstract when private charity exists and is motivated by utility interdependence a non pareto optimal outcome the free rider problem typically arises nevertheless incremental fiscal redistribution cannot achieve a paretian welfare improvement so long as private charity continues at positive levels donors respond to incremental fiscal redistribution by reducing their voluntary contributions by exactly a dollar for every dollar transferred in this way no net transfer is achieved unless incremental fiscal redistribution is pursued to the point where private contributions have been driven to zero alternatively a net transfer may be achieved by fiscal measures which affect donors marginal incentives to donate

whither the nonprofit wage differential estimates from the 1990 census this article provides new estimates of the nonprofit for profit wage differential in the u s economy using observations on 4 1 million private sector employees from the 1990 census i find either zero or slightly positive economy wide wage differences between nonprofit and for profit employees in a standard earnings equation format significant wage differentials are found at the disaggregated occupation and industry level and provide a basis for testing hypotheses explaining nonprofit for profit wage differences

the structure of economic modeling of the potential impacts of climate change grafting gross underestimation of risk onto already narrow science models scientists describe the scale of the risks from unmanaged climate change as potentially immense however the scientific models because they omit key factors that are hard to capture precisely appear to substantially underestimate these risks many economic models add further gross underassessment of risk because the assumptions built into the economic modeling on growth damages and risks come close to assuming directly that the impacts and costs will be modest and close to excluding the possibility of catastrophic outcomes a new generation of models is needed in all three of climate science impact and economics with a still stronger focus on lives and livelihoods including the risks of large scale migration and conflicts

gifts of money and gifts of time estimating the effects of tax prices and available time abstract we develop a model that recognizes interdepence between individuals charitable cash donations and volunteer labor using survey data we estimate giving functions jointly allowing a binding non negativity constraint in one giving equation to affect the form of the other the tax price of money giving is significant in all equations with estimated elasticities of 1 7 for money giving 2 1 for women s time and 1 1 for men s time the complementarity between volunteer labor and cash donations suggests that the effect of tax policy on philanthropy is understated by considering monetary donations alone

utilitarian preferences with multiple priors this paper proposes a method for aggregating individual preferences in the context of uncertainty individuals are assumed to abide by savage s model of subjective expected utility in which everyone has his her own utility and subjective probability disagreement on probabilities among individuals gives rise to uncertainty at the societal level and thus society may entertain a set of probabilities rather than only one we assume that social preference admits a maxmin expected utility representation in this context two pareto type conditions are shown to be equivalent to social utility being a weighted average of individual utilities and the social set of priors containing only weighted averages of individual priors thus society respects consensus among individuals beliefs and does not add ambiguity beyond disagreement on beliefs we also deal with the case in which society does not rule out any individual belief

an accurate measurement of the crowd out effect income effect and price effect for charitable contributions in the past empirical research on charitable contributions has focused on two issues estimating the income and price elasticities of contributions and estimating the extent to which government funding crowded out private contributions the two fundamental problems in all these studies are the differences in the underlying conceptual models and the use of imperfect data for empirical analysis this paper addresses both of these problems

modeling charitable contributions of time and money abstract public goods theory predicts that government spending on charity can perfectly crowd out charitable contributions empirical research has found little support for the perfect crowd out hypothesis however the empirical work only measures part of a contributor s total contribution gifts of money contributors also volunteer labor this article extends the public goods model to the case in which individuals contribute both time and money to a charity that in turn produces a public good the model suggests that charitable contributions of time and money are perfectly substitutable in equilibrium this result offers new interpretations for existing empirical observations and suggests a new test of the crowd out hypothesis the implications of the model are empirically tested using a national survey of charitable activity

charity donations in the uk new evidence based on panel data abstract this paper presents a set of panel data estimates for 159 of the most prominent uk charities for the period 1983 1990 in evaluating alternative specifications we settle on a fixed effects estimation social welfare charities are shown to fund raise short of the point at which net revenues are maximized whereas health and overseas charities are found to net revenue maximize religious charities maximize total revenues estimates of price and fund raising elasticities are presented for charities overall and for four cohorts for alternative income sources no evidence of crowding out is found

the demand for products linked to public goods evidence from an online field experiment abstract we conduct a field experiment at a nonprofit organization s online store to study how demand changes when consumers purchases can generate revenue for a charitable cause when purchases can trigger a small donation by an outside anonymous group consumers respond strongly and apparently without regard for the specific conditions that trigger the donation consumers respond similarly when the outside donation requires a personal donation which consumers generally decline when the outside donations are relatively large however consumers appear to pay close attention to the trigger conditions and increase their purchases only where needed to generate the outside donation overall increasing the salience of financial incentives weakens consumers positive responses to the outside group s donation pledges we also present evidence that the donation pledges have positive long term effects on demand and may reduce price sensitivity

volunteer labor supply abstract we model the supply of volunteer labor which received an explicit wage of zero quantitatively important it constituted over 5 percent of the entire labor supply in the united states in 1980 both consumption and investment models are considered the former positing volunteering as an ordinary consumer good while the latter posits it as a means of obtaining on the job experience empirical estimation based on survey data discloses statistically significant effects of price and income variables on the supply of volunteer labor

charitable giving by married couples revisited abstract this paper investigates the effect of gender differences and household bargaining on charitable giving i replicate the study of andreoni brown and rischall 2003 using a different data set the recently available panel study of income dynamics psid supplement on charitable giving and test the sensitivity of their results to inclusion of additional control variables and the endogeneity of the tax price of giving first focusing on singles i find that males and females have significantly different tendencies toward giving to different areas of charitable activity next comparing households in which husband and wife make a joint decision on donations with those in which couples separately decide or assign a sole decisionmaker i show that bargaining over giving increases the amount of charitable contributions by almost 7 percent

voluntary activities and daily happiness in the united states this article analyzes differences in daily happiness between those individuals in the united states who perform voluntary activities during the day and those who do not using the well being module of the american time use survey 2010 we find that those who devote any time to voluntary activities during the day report higher levels of daily happiness than those who do not comparing the happiness obtained from a range of activities we find that volunteering is among the most enjoyable indicating that time spent on voluntary activities is utility enhancing we document that the effect of voluntary activities on the experienced utility of individuals can be decomposed into a time composition effect and an activity effect with the latter explaining between 11 and 46 of the observed difference jel d13 j16 j22

do tax incentives affect charitable contributions evidence from public charities reported revenues this paper estimates the effect of the charitable contribution tax deduction on charities donation revenue from charities tax filings a one percent increase in the tax cost of giving causes charitable receipts to fall by about four percent an effect three times larger the consensus in the literature further analysis reveals substantial heterogeneity in the tax response by subsector health care and home care are more tax sensitive than other charities while higher education and arts are less tax sensitive the results are consistent with substantial tax response heterogeneity within the sample and between sampled and unsampled charities implying that the mean tax elasticity of charitable contributions is a poor predictor of tax incentive effects for individual charities

multinational corporation internationalization in the service sector a study of japanese trading companies this paper extends chang s 1995 sequential investment theory to include multinational corporations mncs in service industries given this sector s large and growing impact on the global economy to facilitate an examination of service mnc internationalization patterns we develop a new typology of service investment i e core global related local unrelated global and unrelated local based on business relatedness and location specificity we test this typology on a sample of large japanese trading companies our results suggest that the initial investments of service mncs are closely related to their core businesses and are less location specific but that subsequent investments are less related to firms core services and are more location specific a pattern similar to the traditional view on manufacturing mncs we extend our analysis to examine several case studies to provide a richer context for these findings in addition we examine the performance implications of internationalization our findings suggest that firms that internationalize through early investments that are closely related to their core activities outperform those in unrelated businesses over time but that this performance gap between related and unrelated foreign investments diminishes in more advanced stages of internationalization

effects of property rights on labor costs of nonprofit firms an application to the day care industry this paper estimates differences in labor costs between nonprofit and for profit firms in the day care industry a theoretical model which draws on the property rights literature as well as recent theo ries of nonprofit labor markets predicts that the magnitude and sign of the nonprofit salary differential will depend on specific characteristics of the samples analyzed empirical results reveal that in th e most competitive segment of the day care industry the nonprofit salary differential is insignificant however in the less competitive government subsidized segment of the industry the nonprofit different ial is significantly positive it ranges from 5 percent to 10 percent copyright 1988 by blackwell publishing ltd

how do we know that real wages are too high it is common belief that the wages that we observe are above the level that would prevail in a competitive labour market and also it is common to believe that wage moderation should be encouraged as a way to keep unemployment down this paper considers whether we can have confidence in these beliefs it presents a number of models designed to cast doubt on the conventional wisdom first we show that in an efficiency wage model in which there is involuntary unemployment a binding minimum wage may increase employment we then present a general equilibrium matching model in which there is involuntary unemployment but wages are below market clearing levels and raising wages can reduce unemployment we then consider the empirical evidence on employment and wage determination to argue that it is just as consistent with this model as with models in which wages are at or above market clearing levels

property rights and wages the case of nursing homes in this paper we develop the implications of the property rights theory of the firm for wage determination and test the model using data from the u s nursing home industry the main theoretical prediction is that any attenuation of property rights will lead to higher wage rates for the firm s employees the empirical evidence indicates that indeed profit maximizing nursing homes do pay the lowest wage rates for given quality labor and that the stronger the cost minimizing incentives provided by medicaid reimbursement programs the lower the wage rate paid by these nursing homes

factors affecting export intermediaries service offerings the british example this study attempts to determine and explain the service offering behavior of british export intermediaries eis it was empirically confirmed that eis offer two categories of services transaction creating and physical fulfillment services it was postulated that the extent to which an ei offers these types of services is influenced by a set of factors that are internally product market supplier and buyer related empirical tests on a sample of 135 british eis established that an ei s exporting role number of employees amount of undifferentiated products carried number of suppliers and number of countries served all have a direct impact on an ei s service offering behavior

on multiple discount rates we propose a theory of intertemporal choice that is robust to specific assumptions on the discount rate one class of models requires that one utility stream be chosen over another if and only if its discounted value is higher for all discount factors in a set another model focuses on an average discount factor yet another model is pessimistic and evaluates a flow by the lowest available discounted value

the impact of charitable subsidies on religious giving and attendance evidence from panel data the literature documents that charitable giving is responsive to tax subsidies but often ignores the spillover effects of such policies this paper investigates the spillover effects of charitable subsidies on religious participation using individual level panel data the results show that religious giving and participation are complements the implied cross price elasticity of religious participation with respect to the after tax price of giving is 0 27 furthermore a 1 increase in the amount of religious contributions is associated with a 0 4 increase in religious attendance these results are robust under several different specifications and highlight the positive externalities created by charitable subsidies

social networks and private philanthropy abstract a theoretical model is provided in which an individual s social network enhances the consumption benefits from the public good we find conditions under which investments in network enhancing infrastructure would encourage individuals to donate time and money to charity an empirical investigation of the link between networks and private philanthropy is undertaken using the canadian national survey of giving volunteering and participating we find strong evidence that networks promote donations of time and money

globalization and location choice an analysis of us multinational firms in 1980 and 2000 in this paper we examine foreign location choices of the top 100 us multinational corporations mncs in 1980 and 2000 we first ask whether there has been a change in mnc foreign location choice in this two decade period second we explore the underlying reasons of location change by focusing on country level factors accounting for firm industry and regional level explanations our findings suggest first that the extent of mncs activities around the globe is more extensive than assumed by regionalists arguments and well beyond ohmae s triad but still less widespread than claimed by the globalists the two main traditions within the globalization regionalization debate second we uncover an interesting de location pattern in this period third we develop an integrative framework where both economic and institutional cultural arguments are shown to influence mncs foreign location choice in different ways we conclude with a discussion of our findings and provide suggestions for future research

the veil of public ignorance abstract a theory of cooperative choice under incomplete information is developed in which agents possess private information at the time of contracting and have agreed on a utilitarian standard of evaluation governing choices under complete information the task is to extend this standard to situations of incomplete information our first main result generalizes harsanyi s j polit econ 63 1955 309 classical result to situations of incomplete information assuming that group preferences satisfy bayesian coherence and interim pareto dominance these axioms are mutually compatible if and only if a common prior exists we argue that this result partly resolves the impossibility of bayesian preference aggregation under complete information

the evolution of the u s international trade intermediary in the 1980s a dynamic model international trade intermediaries such as export management companies have long existed in the united states many studies and reports have provided snapshots of their activities and roles over time their evolution however has hardly been researched mainly for lack of an appropriate dynamic model this paper integrates various conceptual frameworks and theories to develop a useful mode of the evolution of the u s international trade intermediary in the 1980s
