testing risk aversion and nonexpected utility theories abstract this paper tests risk aversion and compares several nonexpected utility theories using paired comparisons economic hypotheses associated with risk aversion are found not to hold in preference data expected utility with rank dependent probability is found to provide a smooth representation of preference for a wide range of preference types

does financial education impact financial literacy and financial behavior and if so when in a meta analysis of 126 impact evaluation studies we find that financial education significantly impacts financial behavior and to an even larger extent financial literacy these results also hold for the subsample of randomized experiments rcts however intervention impacts are highly heterogeneous financial education is less effective for low income clients as well as in low and lower middle income economies specific behaviors such as the handling of debt are more difficult to influence and mandatory financial education tentatively appears to be less effective thus intervention success depends crucially on increasing education intensity and offering financial education at a teachable moment

international portfolio diversification with generalized expected utility preferences this paper revisits the home bias puzzle the relatively low interna tional diversification of portfolios we suggest that part of the diversifi cation puzzle may be due to reliance on the conventional capm model as the benchmark predicting patterns of diversification we compare the asset diver sification patterns of agents who maximize a generalized expected utility geu to the diversification of agents who maximize the conventional expected utility eu specifically we derive the patterns of diversification for agents who maximize a rank dependent expected utility attaching more weight to bad than to good outcomes in contrast to the probability weights used in a conventional expected utility maximization we show that agents who maximize a geu exhibit first order risk aversion and tend to refrain from di versification in contrast to the diversification of agents who maximize the eu for a given covariance structure we identify a cone of diversifica tion the range of domestic and foreign yields leading to a positive demand for both equities greater downside risk aversion increases the threshold of yields leading to diversification shifting the cone of diversification upwards and rightwards thus greater downsiderisk aversion narrows the range of foreign yields leading to diversification for a given domestic yield ceteris paribus greater downside risk aversion reduces the feasible hetero geneity of normalized excess yields associated with diversification conse quently we argue that first order risk aversion should be added to the explanatory factors that account for the observed diversification patterns

prices or knowledge what drives demand for financial services in emerging markets this brief summarizes the results of a gender impact evaluation study entitled prices or knowledge what drives demand for financial services in emerging markets conducted in 2008 in indonesia the study observed that financial development is critical for growth but its micro determinants are not well understood financial literacy training has no impact on the probability of opening a bank account although it does have an impact among those with low levels of education and financial literacy a change from 3 to 14 led to a 7 6 percent increase in the probability of owning a bank account the results hold two years after a study funding for the study derived from world bank hbs division of research and faculty development

political and institutional determinants of fiscal policy in the european community in recent theoretical and empirical research the variation in political and institutional arrangements which may affect the process of national policy formation is examined in order to explain cross country differences with respect to fiscal policies pursued in this paper we build upon this literature and examine whether and how cross country differences in debt accumulation and public sector size of member countries of the european community during the 1980s can be explained we conclude that the growth of government debt is positively related to the frequency of government changes and negatively to sound budgetary procedures in countries with left wing governments the growth of the share of government spending in total output generally tends to be higher

savings in transnational households a field experiment among migrants from el salvador abstract we implemented a randomized field experiment that tested ways to stimulate migrants savings in their origin country we find that migrants value opportunities to exert greater control over financial activities in their home countries we offered u s based migrants bank accounts in el salvador randomly varying migrant control over el salvador based savings by offering different accounts across treatments migrants offered the greatest degree of control accumulated the most savings impacts likely represent increases in total savings there is no evidence that savings increases were simply reallocated from other savings mechanisms enhanced control over home country savings does not affect remittances sent home

failure of blackwell s theorem under machina s generalization of expected utility analysis without the independence axiom abstract considerable evidence suggests that the independence axiom of expected utility theory is not empirically supported in response machina has generalized expected utility theory in such a way that the independence axiom is not required most of the basic concepts and results of expected utility theory still hold under machina s generalization however blackwell s theorem a fundamental result in information economics fails to hold under machina s generalization of expected utility theory without the independence axiom

rank dependent probabilities within the framework of expected utility theory with rank dependent probabilities the authors present a hypothesis concerning the shape of the probability transformation function this hypothesis is consistent with the preference reversals phenomenon in particular it is consistent with the finding 1 that the frequency of reversals is higher when the p bet is preferred to the corresponding bet than when the bet is preferred over the corresponding p bet and 2 that the bet is chosen more frequently than the corresponding p bet it is also consistent with aversion to fair symmetric risk and with the simultaneous participation in actuarially unfair lotteries and insurance copyright 1990 by royal economic society

government spending and budget deficits in the industrial economies fiscal policy nouriel roubini and jeffrey sachs this paper examines the evolution of the size of government and of budget deficits in oecd economies we highlight the rapid increase in government spending in the 1970s the sharp rise in budget deficits and public debt after 1973 and the reversal in these trends in the 1980s the increase in the size of government was associated in part with the slowdown in growth after 1973 but also reflected gradual adjustment of the ratio of spending to output towards a long run target which depends on political and institutional characteristics of the economy the political orientation of the government the degree of wage indexation and the degree of stability of the political system such factors also explain the size of budget deficits when faced with an adverse shock subsequent deficit reduction requires a measure of political consensus we note that such consensus is hard to achieve in multi party coalitions in consequence countries with such a political structure tended in consequence countries with such a political structure tended toin consequence countries with such a political structure tended to experience much more rapid increases in their debt gnp ratios

a behavioral analysis of stochastic reference dependence we examine the reference dependent risk preferences of k oszegi and rabin 2007 focusing on their choice acclimating personal equilibria concept we relate their model to other existing generalizations of expected utility we demonstrate that linear gain loss choice acclimating personal equilibria is equivalent to the intersection of quadratic utility and pessimistic rank dependent utility however it has only a trivial intersection i e expected utility with other referencedependent preferences we use these relationships to extend our understanding of k oszegi and rabin s model linking their functional form to behavior demonstrating new applications and deriving new tests and looking for support in existing experimental data 98 words

insurance with multiple insurers a game theoretic approach this paper studies the set of pareto optimal insurance contracts and the core of an insurance game our setting allows multiple insurers with translation invariant preferences we characterise the pareto optimal contracts which determines the shape of the indemnities closed form and numerical solutions are found for various preferences that the insurance players might have determining associated premiums with any given optimal pareto contract is another problem for which economic based arguments are further discussed we also explain how one may link the recent fast growing literature on risk based optimality criteria to the pareto optimality criterion and we show that the latter is much more general than the former one which according to our knowledge has not been pointed out by now further we extend some of our results when model risk is included i e there is some uncertainty with the risk model and or the insurance players make decisions based on divergent beliefs about the underlying risk these robust optimal contracts are investigated and we show how one may find robust and pareto efficient contracts which is a key decision making problem under uncertainty

the ross characterization of risk aversion strengthening and extension this paper offers an interpretive comparison of the arrow pratt and ross characterizations of comparative risk aversion for expected utility maximizers the tools used in this comparison are then applied to obtain a strengthening of the ross cha racterization this strengthened result is in turn extended to the ca se of general smooth nonexpected utility preferences over probabili ty distributions copyright 1987 by the econometric society

bargaining and boldness abstract we study a multiperson bargaining problem with general risk preferences through the use of shaked s game of cycling offers with exogenous breakdown if preferences are smooth then as the risk of breakdown vanishes the limiting outcome is one in which bargainers are equally marginally bold where a bargainer s marginal boldness measures his willingness to risk disagreement in return for a marginal improvement in his position under smoothness any ordinal nash solution is an equally marginally bold outcome however unlike the concept of the ordinal nash solution a unique equally marginally bold outcome exists in natural cases in particular if all bargainers have risk averse preferences of the rank dependent expected utility type for these preferences the equally marginally bold outcome maximizes a bargaining power adjusted asymmetric nash product where the degree of asymmetry is determined by the disparity in the marginal valuation of certainty among bargainers journal of economic literature classification numbers c72 c78 d81

on the optimal design of lotteries is globally concave since thearguments against the plausibility of a convex utility function advanced in the previous sectionin relation to eu theory apply with equal force to the rdeu model by contrast as is shownbelow these arguments do not apply to risk seeking behavior associated with the possibility that

comparative statics and non expected utility preferences abstract researchers have shown that many though not all of the basic results of expected utility analysis can be more or less directly generalized to non expected utility preferences this paper describes the essential difference between results which can be extended in this manner and those which cannot and shows that an important family of comparative statics theorems falls into the former class

some remarks on quiggin s anticipated utility abstract this remark proves that quiggin s anticipated utility function may solve the allais paradox and the common ratio effect for some generalizations of these it is needed to assume that the decision weight function is concave

on the economic meaning of machina s frechet differentiability assumption abstract this note shows that m j machina s 1982 econometrica 50 277 323 assumption that preferences over lotteries are smooth has some economic implications we show that frechet differentiability implies that preferences represent second order risk aversion as well as conditional second order risk aversion this implies among other things that decision makers buy full insurance only at the absence of marginal loading we also show that with constant absolute and relative risk aversion expected value maximization second order risk aversion and frechet differentiability are equivalent journal of economic literature classification number d81

local risk aversion in the rank dependent expected utility model first order versus second order effects abstract we evaluate locally the risk premium of a lottery in the framework of the rdeu model as the sum of two terms the first is a measure of risk aversion while the second is a measure of spreading aversion

existence and uniqueness of ordinal nash outcomes abstract in this paper we present necessary and sufficient conditions for existence and uniqueness of ordinal nash outcomes these outcomes are derived from the ordinal nash solution a reinterpretation and an extension of the nash bargaining solution that allows bargainers to have preference relations that are more general than expected utility our task is undertaken by the construction of a new notion called induced utilities journal of economic literature classification number c78

a generalization of pratt arrow measure to nonexpected utility preferences and inseparable probability and utility the pratt arrow measure of local risk aversion is generalized for then dimensional state preference model of choice under uncertainty in which the decision maker may have inseparable subjective probabilities and utilities unobservable stochastic prior wealth and or smooth nonexpected utility preferences local risk aversion is measured by the matrix of derivatives of the decision maker s risk neutral probabilities without reference to true subjective probabilities or riskless wealth positions and comparative risk aversion is measured without requiring agreement on true probabilities risk neutral probabilities and their derivatives are shown to be sufficient statistics for approximately optimal investment and financing decisions in complete markets for contingent claims

punishment schedules for capital flight w hat are appropriate penalties to discourage capital flight economic punishments can serve as effective deterrents for economic crimes but the penalties themselves are often costly to impose and enforce good public policy must take these costs into account in addition to the effectiveness of punishment schemes in order to construct a deterrent to economically motivated behaviour the environment that generates this motivation must be well understood we show that the incentives for capital flight can differ in predictable ways this difference in incentives implies that even though standard risk aversion analyses might suggest the opposite it will often be better to penalise larger transactions in a higher proportion than smaller ones a common definition of capital flight is the growth in the stock of one country s claims on non residents that generates income beyond the control of the domestic authorities see for example dooley 1988 rojas suarez 1990 or razin and sadka 1989 this notion is useful because it distinguishes between portfolio motivations for international capital allocation which are desirable on grounds of economic efficiency and movements of capital which are motivated by a desire to evade tax liabilities the latter type of capital movements imposes costs both in terms of lost government revenues and potential distortions in investment decisions we focus therefore on capital movements which are motivated by the illegal desire to shelter investment income from domestic taxation an understanding of capital flight requires a careful and consistent description of the economic environment that generates the motivations for this phenomenon for the remainder of this paper the following assumptions are maintained in order to match as closely as possible conditions that must hold for capital flight to exist

choices involving uncertain probabilities abstract this paper contains an analytic and empirical component the analytic one examines how people should value information on probabilities versus payoffs according to expected utility theory it also examines under what conditions various generalized utility models such as subjective expected utility theory prospect theory and rank dependent utility entail testable predictions for preference for information the empirical component examines people s actual information preferences and to what extent they fit the various models after describing two experiments and their findings it is concluded that generalized utility models are unlikely to offer much insight into risky decision making

the probability premium a graphical representation we illustrate that pratt s probability premium can be given a simple graphical representation allowing a direct comparison to the equivalent but more prevalent concept of risk premium under expected utility we also show that the probability premium s graphical representation under the dual theory mimics that of the risk premium under expected utility

the value of a statistical life under ambiguity aversion abstract the paper shows that ambiguity aversion increases the value of a statistical life if the marginal utility of an increase in wealth is larger if one is alive rather than dead intuitively ambiguity aversion has a similar effect as an increase in the perceived baseline mortality risk and thus operates as the dead anyway effect a numerical example suggests however that ambiguity aversion cannot justify the substantial ambiguity premium apparently embodied in environmental policy making the paper also shows that ambiguity aversion decreases the marginal cost of individual self protection effort but may well decrease its marginal benefit so that the total effect of ambiguity aversion on self protection is unclear

migration networks and microenterprises in mexico are migration networks associated with lower capital costs or the alleviation of capital constraints we examine these questions with data measuring access to remittance flows among small scale entrepreneurs in mexico using a survey of more than 6000 self employed workers and small firm owners located in 44 urban areas of mexico we estimate the impact of attachment to migration networks on the level of capital investment the capital output ratio sales and profits of microenterprises the impact is identified from the geographic pattern of migration from mexico driven by the completion of rail lines in the early 1900s for the full sample of firms we find that migration is associated with higher investment levels and higher profits but not higher sales the strongest effects on investment are in the categories of automobiles tools and inventories when the sample is limited to firms in high capital sectors investment sales and profits all increase with attachment to the migration networks suggesting that attachment to the migration network alleviates capital constraints in those sectors

comment on risk preferences are not time preferences separating risk and time preference andreoni and sprenger 2012a b observe that utility functions are distinct for risk and time preferences and show that their findings are consistent with a preference for certainty we revisit this question in an enriched experimental setting in which subjects make intertemporal decisions under different risk conditions the observed choice behavior supports a separation between risk attitude and intertemporal substitution rather than a preference for certainty we further show that several models including epstein and zin 1989 chew and epstein 1990 and halevy 2008 exhibit such a separation and can account for the overall experimental findings jel c91 d81 d91 risk and time preferences are the cornerstones of economic analyses regarding risk preference expected utility eu has been the predominant theory in which the curvature of the utility index captures risk attitude regarding time preference discounted utility is the most widely used model in which the curvature of the utility index captures intertemporal substitution when risk and time are intertwined integrating the two theories yields discounted expected utility deu which evaluates a contingent consumption plan c c c 3 as follows

taxation of asset income in the presence of a world securities market abstract this paper examines a capm model of world security prices in which governments recognize their ability to influence international security prices via their tax treatment of foreign and domestic investors in this model governments have the incentive to set tax rates such that investors tend to specialize in domestic securities and to restrict net capital flows between countries each country does this to increase the utility of domestic residents taking as given the tax policies of other governments but the net outcome is a reduction in world efficiency and likely a reduction in the utility of all investors

the abcs of financial education experimental evidence on attitudes behavior and cognitive biases this paper uses a large scale field experiment in india to study attitudinal behavioral and cognitive constraints that stymie the link between financial education and financial outcomes the study complements financial education with i participant classroom motivation with pay for performance on a knowledge test ii intensity of treatment with personalized financial counseling and iii behavioral nudges with financial goal setting the analysis finds no impact of pay for performance but significant effects of both counseling and goal setting on real financial outcomes these results identify important complements to financial education that can bridge the gap between financial knowledge and financial behavior change

international migration remittances and household investment evidence from philippine migrants exchange rate shocks how do households respond to overseas members economic shocks overseas filipinos in dozens of countries experienced sudden heterogeneous changes in exchange rates during the 1997 asian financial crisis appreciation of a migrant s currency against the philippine peso leads to increases in household remittances from overseas the estimated elasticity of philippine peso remittances with respect to the exchange rate is 0 60 positive migrant shocks lead to enhanced human capital accumulation and entrepreneurship in origin households child schooling and educational expenditure rise while child labour falls households also work more hours in self employment and become more likely to start relatively capital intensive household enterprises

stochastic dominance in regret theory the regret theory of choice under uncertainty is known to admit intransitivities in preference relations in this paper the stochastic dominance properties of the theory are examined it is shown that the usual definition of first stochastic dominance is not satisfied by regret theoretic preferences and that in general violations of first stochastic dominance are not merely permitted but required an exact characterization of the stochastic dominance rule corresponding to regret theoretic preferences is presented this concept is weaker than the usual definition but stronger than the notion of statewise dominance in which one prospect yields a preferred outcome with probability 1 theories of choice under uncertainty have proliferated in recent years after a long period in which the expected utility eu approach of von neumann and morgenstern 1944 was pre eminent the breakdown of the dominance in eu theory reflects the increasing body of evidence that the choices made by many people systematically violate the predictions of the theory the axiomatic foundations of the theory and in particular the independence axiom have also received severe questioning ever since the famous critique of allais 1953

a theory of anticipated utility abstract a new theory of cardinal utility with an associated set of axioms is presented it is a generalization of the von neumann morgenstern expected utility theory which permits the analysis of phenomena associated with the distortion of subjective probability

beyond baseline and follow up the case for more t in experiments the vast majority of randomized experiments in economics rely on a single baseline and single follow up survey if multiple follow ups are conducted the reason is typically to examine the trajectory of impact effects so that in effect only one follow up round is being used to estimate each treatment effect of interest while such a design is suitable for study of highly autocorrelated and relatively precisely measured outcomes in the health and education domains this paper makes the case that it is unlikely to be optimal for measuring noisy and relatively less autocorrelated outcomes such as business profits household incomes and expenditures and episodic health outcomes taking multiple measurements of such outcomes at relatively short intervals allows the researcher to average out noise increasing power when the outcomes have low autocorrelation it can make sense to do no baseline at all moreover the author shows how for such outcomes more power can be achieved with multiple follow ups than allocating the same total sample size over a single follow up and baseline the analysis highlights the large gains in power from ancova rather than difference in differences when autocorrelations are low and a baseline is taken the paper discusses the issues involved in multiple measurements and makes recommendations for the design of experiments and related non experimental impact evaluations

a cardinal characterization of the rubinstein safra thomson axiomatic bargaining theory in a recent paper rubinstein safra and thomson rst have provided an interesting re examination of the widely applied nash solution for a two person bargaining problem they recast the usual nash bargaining problem into a more natural setting of feasible alternatives with a disagreement outcome the two players are then described by their risk preferences defined on the set of lotteries over the alternatives and the disagreement outcome this enables them to define an ordinal nash solution in terms of the agents risk preferences essentially their ordinal solution is an outcome that is immune against possible objections freeing the definition of the nash solution from utility naturally led rst to extending its scope to non expected utility neu preferences we contend however that the family of neu preferences considered by rst is unduly restrictive the assumptions imposed on the risk preferences by rst essentially exclude any members of the rank dependent expected utility rdeu and betweenness families that can accommodate the very choice paradoxes that stimulated the development of neu theory as these are two of the most extensively analyzed and widely applied neu models in the literature this seems to cast doubt on how broad an extension to neu preferences the rst approach affords we demonstrate however that rst s analysis can be modified so that their conclusion is valid in a wider class of preferences that can include examples of rdeu preferences this class consists of preferences that admit what we term a disagreement linear representation

efficient allocations under ambiguity abstract important implications of the expected utility hypothesis and risk aversion are that if agents have the same probability belief then consumption plans in every efficient allocation of resources under uncertainty are comonotone with the aggregate endowment and if their beliefs are concordant then the consumption plans are measurable with respect to the aggregate endowment we study these two properties of efficient allocations for models of preferences that exhibit ambiguity aversion using the concept of conditional beliefs which we introduce in this paper we provide characterizations of such conditional beliefs for the standard models of preferences used in applications

the political economy of direct legislation direct democracy and local decision making local fiscal referenda the dampening effect on taxes and spending local and regional governments account for an important share of total government spending and given the decentralization trend in oecd nations this is likely to increase how should this spending be governed this article argues that direct democracy is best suited to organize decision making at the state and local level to support this we present the main theoretical arguments on why and how referenda and initiatives affect fiscal policy outcomes the basic argument concerns voter control under representative democracy citizens only have direct control at election time with referenda and initiatives citizens can selectively control their representatives on specific policies whenever they deviate sufficiently from citizens preferences as a result fiscal policy outcomes are likely to more closely reflect voter preferences we empirically test this on swiss data since switzerland provides a natural laboratory for local governance the governance structures of swiss cantons and localities with respect to fiscal issues range from classic parliamentary democracy to pure direct democracy and an important part of spending and taxation is controlled at these levels specifically we estimate an econometric model of fiscal behaviour using data from 1986 to 1997 for the 26 swiss cantons and 1990 data on 134 local communities it is shown that mandatory referenda on fiscal issues at both levels have a dampening effect on expenditure and revenue and at the local level also on public debt combining this with existing empirical evidence leads to a relatively uncontested result namely that elements of direct democracy are associated with sounder public finances better economic performance and higher satisfaction of citizens lars p feld and gebhard kirchgassner

directing remittances to education with soft and hard commitments evidence from a lab in the field experiment and new product take up among filipino migrants in rome this paper tests how migrants willingness to remit changes when given the ability to direct remittances to educational purposes using different forms of commitment variants of a dictator game in a lab in the field experiment with filipino migrants in rome are used to examine remitting behavior under varying degrees of commitment these range from the soft commitment of simply labeling remittances as being for education to the hard commitment of having funds directly paid to a school and the student s educational performance monitored the analysis finds that the introduction of simple labeling for education raises remittances by more than 15 percent adding the ability to directly send this funding to the school adds only a further 2 2 percent the information asymmetry between migrants and their most closely connected household is randomly varied but no significant change is found in the remittance response to these forms of commitment as information varies behavior in these games is shown to be predictive of take up of a new financial product called edupay designed to allow migrants to pay remittances directly to schools in the philippines this take up seems largely driven by a response to the ability to label remittances for education rather than to the hard commitment feature of directly paying schools

the impact of financial literacy training for migrants remittances are a major source of external financing for many developing countries but the cost of sending them remains high in many migration corridors despite efforts to lower these costs by offering new products and developing cost comparison information sources many new and promising inexpensive remittance methods have relatively low adoption rates the lack of financial literacy among migrants has been identified as one potentially important barrier to competition and new product adoption this paper presents the results of a randomized experiment designed to measure the impact of providing financial literacy training to migrants training appears to increase financial knowledge and information seeking behavior and reduces the risk of switching to costlier remittance products but it does not result in significant changes in the frequency of remitting or in the remitted amount

asset demands without the independence axiom an important application of the theory of choice under uncertainty is to asset markets and an important property in these markets is a preference for portfolio diversification if an investor is an expected utility maximizer then s he is risk averse if and only if s he exhibits a preference for diversification this paper examines the relationship between risk aversion and portfolio diversification when preferences over probability distributions of wealth do not have an expected utility representation

international migration remittances and schooling evidence from el salvador abstract we examine the effect of remittances from abroad on households schooling decisions using data for el salvador following the massive war related emigration of the 1980s remittances became a significant source of household income throughout the 1990s we use the cox proportional hazard model to examine the determinants of school attendance measuring income from a source that is uncorrelated with parental schooling remittances we find that remittances have a large significant effect on school retention we estimate that while household income net of remittances has a small though significant impact on the hazard of leaving school in rural and urban areas remittances have a much larger impact on the hazard of leaving school in urban areas the effect of remittances is at its smallest 10 times the size of the effect of other income in rural areas the effect of remittances is about 2 6 times that of other income our finding is of interest in that it suggests that subsidizing school attendance particularly in poor areas may have a large impact on school attendance and retention even if parents have low levels of schooling

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

until the bitter end on prospect theory in a dynamic context many economic and financial decisions depend crucially on their timing people decide when to invest in a project when to liquidate assets or when to stop gambling in a casino we provide a general result on prospect theory decision makers who are unaware of the time inconsistency induced by probability weighting if a market offers a sufficiently rich set of investment strategies then such naive investors postpone their stopping decisions indefinitely we illustrate the drastic consequences of this never stopping result and conclude that probability distortion in combination with naivete leads to unrealistic predictions for a wide range of dynamic setups

the effect of decision weights in bargaining problems abstract bargaining problems are considered where the preferences of the bargainers deviate from expected utility but can be modelled according to rank dependent utility theory under rank dependent utility both the utility function and the probability weighting function influence the risk attitude of a decision maker the same definition of risk aversion leads to two forms of risk aversion utility risk aversion and probabilistic risk aversion the main finding is that these two forms can have surprisingly opposite consequences for bargaining solutions that exhibit a weak monotonicity property in particular in a large class of bargaining problems both increased utility risk aversion and decreased probabilistic risk aversion of the opponent are advantagous for a player this is demonstrated for the kalai smorodinsky bargaining solution the nash bargaining solution does not behave regularly in this respect

risk aversion in the theory of expected utility with rank dependent probabilities expected utility with rank dependent probability theory is a model of decision making under risk where the preference relations on the set of probability distributions is represented by the mathematical expectation of a utility function with respect to a transformation of the probability distributions on the set of outcomes this paper defines based on g teaux differentiability measures of risk aversion for such preferences which characterize the relation more risk averse and applies these measures to the analysis of unconditional and conditional portfolio choice problems

municipal debt in switzerland new empirical results switzerland has experienced extensive institutional reforms at the local level that could influence local debt these reforms have included municipal mergers greater inter communal cooperation reformed political decision making mechanisms and the introduction of new public management measures many of these reforms originated at the cantonal level however the institutional diversity among swiss municipalities hardly has diminished a cross sectional analysis for the 137 largest swiss cities and villages in 2004 shows that direct democratic rights and a high degree of fiscal autonomy lead to a lower level of local debt there is no statistical support for the hypothesis that reforms following the new public management guidelines had an effect on debt levels

developments in non expected utility theory the hunt for a descriptive theory of choice under risk this article reviews recent developments in the economic theory of individual decision making under risk since the 1950s it has been known that individual choices violate the standard model of expected utility in predictable ways considerable research effort has now been devoted to the project of developing a superior descriptive model following an overview of non expected utility theories which distinguishes between conventional and non conventional approaches the paper seeks to assess these alternative models in terms of empirical success using laboratory and field data and theoretical usefulness the closing sections reflect on some new directions emerging in this literature

don t tell on me experimental evidence of asymmetric information in transnational households although most theoretical models of household decision making assume perfect information empirical studies suggest that information asymmetries can have large impacts on resource allocation i demonstrate the importance of these asymmetries in transnational households where physical distance between family members can make information barriers especially acute i implement an experiment among migrants in washington dc and their families in el salvador that examines how information asymmetries can have strategic and inadvertent impacts on remittance decisions migrants make an incentivized decision over how much of a cash windfall to remit and recipients decide how they will spend a remittance migrants strategically send home less when their choice is not revealed to recipients recipients make spending choices closer to migrants preferences when the migrants preferences are shared regardless of whether or not the spending choices are revealed to the migrants suggesting that recipients choices are inadvertently affected by imperfect information

ausi expected utility an anticipated utility theory of relative disappointment aversion abstract in this paper we provide an axiomatization for a representation of preferences over lotteries that is only one parameter richer than expected utility our model is a special case of rank dependent expected utility moreover we show that the same restriction on this parameter is required for risk aversion intuitive comparative static results for a reasonably general class of economically interesting choice problems and accommodating some of the most well known violations of expected utility theory

choice under uncertainty problems solved and unsolved ffifteen years ago the theory of choice under uncertainty could be considered one of the success stories of economic analysis it rested on solid axiomatic foundations it had seen important breakthroughs in the analytics of risk risk aversion and their applications to economic issues and it stood ready to provide the theoretical underpinnings for the newly emerging information revolution in economics 1 today choice under uncertainty is a field in flux the standard theory is being challenged on several grounds from both within and outside economics the nature of these challenges and of our profession s responses to them is the topic of this paper

when can expected utility handle first order risk aversion abstract expected utility functions are limited to second order conditional risk aversion while non expected utility functions can exhibit either first order or second order conditional risk aversion we extend the concept of orders of conditional risk aversion to orders of conditional dependent risk aversion we show that first order conditional dependent risk aversion is consistent with the framework of the expected utility hypothesis our theoretical result proposes new insights into economic and financial applications such as the equity premium puzzle the cost of business cycles and stock market participation our model is compared to the rank dependent expected utility model

who you train matters identifying complementary effects of financial education on migrant households there has long been a concern among policymakers that too much of remittances are consumed and too little saved limiting the development impact of migration financial literacy programs have become an increasingly popular way to try and address this issue but to date there is no evidence that they are effective in inducing savings among remittance receiving households nor is it clear whether such programs are best targeted at the migrant the remittance receiver or both the authors conducted a randomized experiment in indonesia which allocated migrants and their families to a control group a migrant only training group a family member only training group and a training group in which both the migrant and a family member were trained three rounds of follow up surveys are then used to measure impacts on the financial knowledge behaviors and remittance and savings outcomes of the remaining household they find that training both the migrant and the family member together has large and significant impacts on knowledge behaviors and savings training the family member alone has some positive but smaller effects whilst training only the migrant leads to no impacts on the remaining family members the results show that financial education can have large effects when provided at a teachable moment but that this impact varies greatly with who receives training

an index of loss aversion to a considerable extent risk aversion as it is commonly observed is caused by loss aversion several indexes of loss aversion have been proposed in the literature the one proposed in this paper leads to a clear decomposition of risk attitude into three distinct components basic utility probability weighting and loss aversion the index is independent of the unit of payment the main theorem shows how the indexes of different decision makers can be compared through observed choices

intrinsic variability in group and individual decision making the paper examines the random preference model which can explain inherent variability of preferences in managerial and individual decision making and provides axiomatizations for the utility components of two such models differentiated by the structure of core preferences expected utility eu and betweenness like preferences we then examine the possibility of violations of weak stochastic transitivity for these models and for a model with core dual eu preferences such violations correspond to the existence of condorcet cycles and therefore the analysis has implications for managerial decision making and for majority rule voting the paper also investigates implications of its findings for two popular experimental settings this paper was accepted by james smith decision analysis

independent and competing agencies an effective way to control government controlling government is a primary focus of the politico economic literature recently various political institutions have been analyzed from this perspective most importantly balanced budget rules fiscal federalism and direct democracy however one type of institution has been neglected so far elected competitors to the government such institutional competition between the government and an independent agency can be found at the swiss local level where finance commissions compete with the government in some parts of switzerland local finance commissions can ex ante criticize government projects and bring alternative policy proposals onto the political agenda which are then voted on by the citizens thus they become strong competitors to the government we econometrically investigate this institutional setting by comparing the 26 swiss cantons we find the power of the local finance commission to have an economically relevant statistically significant and robust negative effect on the tax burden and on public expenditures

a definition of uncertainty aversion a definition of uncertainty or ambiguity aversion is proposed it is argued that the definition is well suited to modelling within the savage as opposed to anscombe and aumann domain of acts the defined property of uncertainty aversion has intuitive empirical content behaves well in specific models of preference multiple priors and choquet expected utility and is tractable tractability is established through use of a novel notion of differentiability for utility functions called eventwise differentiability

star shaped probability weighting functions and overbidding in first price auctions there is a debate about whether risk aversion is the main source of overbidding in a first price independent private values auction as an alternative we adopt a non expected utility framework and identify an interpretable property on the probability weighting function which always induces overbidding

stochastic dominance analysis without the independence axiom we characterize the consistency of a large class of nonexpected utility preferences including mean variance preferences and prospect theory preferences with stochastic orders for example stochastic dominances of different degrees our characterization rests on a novel decision theoretic result that provides a behavioral interpretation of the set of all derivatives of the functional representing the decision maker s preferences as an illustration we consider in some detail prospect theory and choice acclimating preferences two popular models of reference dependence under risk and we show the incompatibility of loss aversion with prudence this paper was accepted by james smith decision analysis

do large cabinets favor large governments evidence on the fiscal commons problem for swiss cantons abstract the fiscal commons problem is one of the most prominent explanations of excessive spending in political economics for a panel of the 26 swiss cantons over the 1980 1998 periods this paper explores the role of fragmented governments on fiscal policy outcomes we distinguish between two variants of fragmented governments cabinet size and coalition size in addition we analyze whether constitutional rules for executive and legislature as well as formal fiscal restraints shape the size of government and how different rules interact with fragmentation the results indicate that the number of ministers in the cabinet is positively associated with the size of government while fiscal referendums effectively restrict the size of government there is also evidence that fiscal referendums relax the fiscal commons problem to some extent

approximate portfolio analysis abstract this paper presents a portfolio selection model based on the idea of approximation the model describes a portfolio by its decumulative distribution curve and a preference structure by a family of convex indifference curves it prescribes the optimal portfolio as the one whose decumulative curve has the highest tangent indifference curve the model extends the mean variance model in the sense that it does not restrict the return distributions of assets to be normal while under the assumption of normality the model simplifies to the mean variance model the model has a measure of risk attitudes that resembles the arrow pratt measure while combining both wealth and probability attitudes using this measure we show that the smaller the curvature of a value function and the larger the curvature of a weighting function the more risk averse an agent

intrinsic preference for information abstract suppose agents value information not only to make contingent plans but also intrinsically how are such attitudes toward information related to attitudes toward risk we generalize the kreps porteus recursive expected utility model dropping both recursivity and expected utility there is a geometric analogy between risk and information we characterize intrinsic information loving in general by a substitution property analogous to multivariate risk loving and for smooth preferences by the convexity of gateaux derivatives even with recursivity preference for information does not imply expected utility we provide an example we examine connections between information loving and risk aversion for early and late resolving risks journal of economic literatureclassification numbers d80 d81
