Aging societies face a fundamental challenge: How to represent future oriented policies in the politics of today? Voting age reforms and, more generally, policies that encourage the participation of the youth in politics are discussed as one solution. In this report, we study whether voting age reforms are radical enough to save us from gerontocracy. We show that there are certain policy fields that have strong age gradients. Although these are very far from being linear and often go in unexpected directions compared to a view that sees voters as simple self-interested actors.

Condorcet domains are sets of preference orders such that the majority relation corresponding to any profile of preferences from the domain is acyclic. The best known examples in economics are the single-peaked, the single-crossing, and the group separable domains. We survey the latest developments in the area since Monjardet's magisterial overview (2009), provide some new results and offer two conjectures concerning unsolved problems. The main goal of the presentation is to illuminate the rich internal structure of the class of maximal Condorcet domains. In an appendix, we present the complete classification of all maximal Condorcet domains on four alternatives obtained by Dittrich (2018).

We study an experiment of the students-proposing deferred acceptance mechanism (DA) in matching markets where firms are matched with students. We investigated the two different situations: (i) Students know firms' preferences and firms submit their true preference, (ii) Students know firms' preferences and firms submit a higher ranking to students who give them higher ranking. This experiment confirms that the matching results under DA in uence students' preference formation, which decreases the degree of stability. If firms do not submit their true preferences, students also do not submit their true preferences. As a result, the situation induces instability. Moreover, we find the new pattern of submitted preferences - compromise strategy. If there is an extreme option, students will tend to prefer the in-between option.

Beauty has been used as a fast and frugal heuristic, and therefore an important determinant of choice, as highlighted in research by Hamermesh. In a world of asymmetric information, beauty represents a proxy for objective characteristics or an object of desire, according to an individual's preferences. A correlate of beauty, sexiness, has been used in sports to choose trainers or even to select the athletes expected to perform best, with people paying a premium for this beauty or sexiness. We argue that beauty can be a good or bad heuristic depending on the objective relationship between beauty and what it proxies. When it is a bad heuristic, it generates sub-optimal outcomes for sports organizations. We discuss the conditions under which the beauty or sexiness heuristic generates sub-optimal outcomes, why rational agents choose such a heuristic, and the conditions under which bad heuristics are sustainable. We also discuss this heuristic and the beauty premium in the context of Becker's economic theory of discrimination, wherein rational decision-makers trade-off material considerations for the utility gained by contracting beautiful and sexy individuals. The latter has implications for the economic sustainability of an organization.

Prozent-Hürden führen normalerweise dazu, dass Stimmen verfallen, was der Gleichheit der Wahl widerspricht und die Chancen kleinerer sowie neuer Parteien mindert. Es gibt mehrere mögliche Auswege, z. B. durch Präferenzwahl. Noch einfacher ist es, wenn jede Partei angibt, an welche andere Partei ihre Stimmen gehen sollen, falls sie selbst an der Prozent-Hürde scheitert. Electoral thresholds usually cause votes to lapse, which contradicts the equality of votes and reduces the chances of smaller and new parties. There are several possible ways out, e.g. by preferential voting. An even easier solution is that each party specifies which other party should get its votes if it fails to meet the electoral threshold.

Redistribution differs widely across countries, but our understanding of why this is the case is limited. In democracies, the extent of redistribution should ultimately reflect citizens' preferences. We measure preferences for redistribution in six developed countries through internationally standardized questions in which respondents are faced with realistic budgetary constraints on their choice. We also measure a broad array of demographic, attitudinal, and ideological characteristics and examine their correlations with the preferred pattern of redistribution. As expected, individual income is associated with lower demand for redistribution, but this relationship loses significance once other factors are controlled for. Beliefs on social mobility have, in the aggregate, the largest effect in reducing demand for redistribution, the effect being largest in the US but insignificant in Italy and Slovenia. Trust in government has a negative effect on demand for redistribution across all countries. In line with other studies, we interpret this result as evidence that people believing that the political élite is corrupt demand more redistribution. Financial security, a proxy for the Prospect of Upward Mobility hypothesis, is also a significant correlate of preferences for redistribution, the effect being largest in Japan but small in the UK and Slovenia. Finally, discrimination of racial minorities is associated with lower demand for redistribution, but the effect is only significant in the US and Germany. Overall, the main theories that have been proposed to account for preferences for redistribution are confirmed to be valid, but with significant variation across countries.

In this paper, we use a hypothetical choice methodology to robustly estimate preferences for workplace attributes. Undergraduate students are presented with sets of jobs that vary in their attributes (such as earnings and job hours flexibility) and asked to state their probabilistic choices. We show that this method robustly identifies preferences for various job attributes, free from omitted variable bias and free from considering the equilibrium matching of workers to jobs. While there is substantial heterogeneity in preferences, we find that women, on average, have a higher willingness to pay for jobs with greater work flexibility (lower hours, and part-time option availability) and job stability (lower risk of job loss), while men have a higher willingness to pay for jobs with higher earnings growth. In the second part of the paper, using data on students' perceptions about the types of jobs that would be offered to them conditional on their college major choices, we relate these job attribute preferences to major choice. We find that students perceive jobs offered to humanities majors to have fewer hours, more worktime flexibility, and higher stability than jobs offered to economics/business majors. These job attributes are found to play a role in major choice, with women exhibiting greater sensitivity to nonpecuniary job attributes in major choice.

We consider an OLG model (of a socialization process) where continuous traits are transmitted from an adult generation to the children. A weighted social network describes how children are influenced not only by their parents but also by other role models within the society. Parents can invest into the purposeful socialization of their children by strategically displaying a cultural trait (which need not coincide with their true trait). Based on Nash equilibrium behavior, we study the dynamics of cultural traits throughout generations. We provide conditions on the network structure that are sufficient for long–run convergence to a society with homogeneous subgroups. In the special case of quadratic utility, the condition is that each child is more intensely shaped by its parents than by the social environment. Our model also represents an extension of the classical DeGroot model of opinion formation for which we introduce strategic interaction in choice of expressed opinions (in our setup: traits). We show that under strategic interaction convergence is slower and for convergence we need more restrictive necessary and sufficient conditions than in the DeGroot model.

We consider a network of players endowed with individual preferences and involved in interactions of various patterns. We show that their ability to make choices according to their preferences is limited, in a specific way, by their involvement in the network. The earlier literature demonstrated the conflict between individuality and peer pressure. We show that such a conflict is also present in contexts in which players do not necessarily aim at conformity with their peers. We investigate the consequences of preference heterogeneity for different interaction patterns, characterize corresponding equilibria and outline the class of games in which following own preferences is the unique Nash equilibrium. The introduction of personal preferences changes equilibrium outcomes in a non-trivial fashion: some equilibria disappear, while other, qualitatively new, appear. These results are robust to both independent and interdependent relationship between personal and social utility components.

In many markets insurers are barred from price discrimination based on con- sumer characteristics like age, gender, and medical history. In this paper, I build on a recent literature to show why such policies are inefficient if consumers differ in their willingness-to-pay for insurance conditional on the insured losses they generate. Using administrative claims data, I then show that this type of demand heterogeneity is empirically relevant in a consumer health plan setting. Younger and older consumers and men and women reveal strikingly different demand for health insurance, conditional on their objective medical spending risk. This implies that these groups must face different prices so as to sort themselves efficiently across insurance contracts. The theoretical and empirical analysis highlights a fundamental trade-off between equity and efficiency that is unique to selection markets.

A key open question for theories of reference-dependent preferences is: what determines the reference point? One candidate is expectations: what people expect could affect how they feel about what actually occurs. In a real-effort experiment, we manipulate the rational expectations of subjects and check whether this manipulation influences their effort provision. We find that effort provision is significantly different between treatments in the way predicted by models of expectation-based, reference-dependent preferences: if expectations are high, subjects work longer and earn more money than if expectations are low.

This paper surveys approaches to preference diversity measurement. Applying preference diversity axiomatics, a generalization of the Alcalde-Unzu and Vorsatz (2016) criterion, is developed. It is shown that all previously used indices violate this criterion. Two new indices (geometric mean based and leximaxbased)are developed that satisfy a new criterion. Leximax-based orders act as a polarization index and are compared with Can et al.’s (2015) polarization index. The paper concludes by formulating a new open question: the preference profile reconstruction conjecture.

We develop a novel computerized real effort task, based on moving sliders across a screen, to test experimentally whether agents are disappointment averse when they compete in a real effort sequential-move tournament. We predict that a disappointment averse agent, who is loss averse around her endogenous choice-acclimating expectations-based reference point, responds negatively to her rival's effort. We find significant evidence for this discouragement effect, and use the Method of Simulated Moments to estimate the strength of disappointment aversion on average and the heterogeneity in disappointment aversion across the population.

Quasilinear preferences on a public good and a numeraire good are limits of preferences where both goods are normal. The set of equilibria of the voluntary contribution (or private provision) game is easily characterized under quasilinearity by: top valuators aggregately contribute their common stand-alone contribution, whereas non-top valuators contribute nothing. Because, as long as preferences are randomly selected, there will typically be a single top valuator, it follows that, typically, the equilibrium is unique, with all players but one contributing nothing, hence “free riding” in the sense of the ordinary English usage of the expression. The upper-hemicontinuity of the Nash equilibrium correspondence implies that this is also the case when both goods are strictly normal, but the wealth effects on the public good are small.

We consider allocation problems with indivisible goods when agents’ preferences are single-peaked. Two natural procedures (up methods and temporary satisfaction methods) are proposed to solve these problems. They are constructed by using priority methods on the cartesian product of agents and integer numbers, interpreted either as peaks or opposite peaks. Thus, two families of solutions arise this way. Our two families of solutions satisfy properties very much related to some well-known properties studied in the case of perfectly divisible goods, and they have a strong relationship with the continuous uniform and equal-distance rules, respectively.

We prove that a mixture continuous preference relation has a utility representation if its domain is a convex subset of a finite dimensional vector space. Our condition on the domain of a preference relation is stronger than Eilenberg (1941) and Debreu (1959, 1964), but our condition on the continuity of a preference relation is strictly weaker than the usual continuity assumed by them.

This paper studies collective decision making with regard to convex risk measures: It addresses the question whether there exist nondictatorial aggregation functions of convex risk measures satisfying Arrow-type rationality axioms (weak universality, systematicity, Pareto principle). Herein, convex risk measures are identified with variational preferences on account of the Maccheroni-Marinacci-Rustichini (2006) axiomatisation of variational preference relations and the Föllmer- Schied (2002, 2004) representation theorem for concave monetary utility functionals. We prove a variational analogue of Arrow's impossibility theorem for finite electorates. For infinite electorates, the possibility of rational aggregation depends on a uniform continuity condition for the variational preference profiles; we prove variational analogues of both Campbell's impossibility theorem and Fishburn's possibility theorem. The proof methodology is based on a model-theoretic approach to aggregation theory inspired by Lauwers-Van Liedekerke (1995). An appendix applies the Dietrich-List (2010) analysis of majority voting to the problem of variational preference aggregation.

Die für 2004 geplante Erweiterung der Europäischen Union auf 25 Mitgliedstaaten bringt enorme Herausforderungen für das institutionelle Regelwerk mit sich. Besonders brisant ist die Zuordnung einzelner Politikbereiche auf nationale oder europäische Entscheidungsinstanzen. Der vorliegende Beitrag rückt die Meinung der europäischen Bürger zu dieser Frage in den Mittelpunkt. Auf der Grundlage von Umfragen des Eurobarometer quantifizierten Prof. Dr. Joachim Ahrens, European Business School, International University Schloß Reichartshausen, und Martin Meurers, ifo Institut, die Heterogenität im Meinungsbild in der gegenwärtigen und in einer erweiterten Union und analysieren anhand der ermittelten Präferenzen für oder gegen eine EU-Kompetenz in einzelnen Politikbereichen die Implikationen für die Entscheidungsprozesse im Europäischen Ministerrat.

We develop a theory of intergenerational transmission of preferences that rationalizes the choice between alternative parenting styles (as set out in Baumrind 1967). Parents maximize an objective function that combines Beckerian altruism and paternalism towards children. They can affect their children's choices via two channels: either by influencing children's preferences or by imposing direct restrictions on their choice sets. Different parenting styles (authoritarian, authoritative, and permissive) emerge as equilibrium outcomes, and are affected both by parental preferences and by the socioeconomic environment. Parenting style, in turn, feeds back into the children's welfare and economic success. The theory is consistent with the decline of authoritarian parenting observed in industrialized countries, and with the greater prevalence of more permissive parenting in countries characterized by low inequality.

The paper investigates teachers' decisions to leave the profession. First we examine the role of earnings and earnings in alternative occupations in these decisions, and then the paper discusses how the public sector wage increase in 2002 has effected exiting decisions of teachers. Using large merged administrative data-sets duration models were estimated. First binary choice Cox proportional hazard models (leaving teaching profession or not), then competing risk models which distinguish exits to another occupation and exits to no-working state. Results show, that earnings matter. Higher wages reduce the probability of exiting teacher profession to go to another occupation or to non-employment. The public sector wage increase has decreased the probability of leaving the teacher profession for inexperienced teachers temporarily, but one or two years after the effect disappeared. For experienced teachers who are older than 51 year-olds the wage increase found to reduce attrition.

We analyze equilibria of two-player contests where players have intention-based preferences. We find that players invest more effort compared to the case with selfish preferences and are even willing to exert effort when the monetary value of the prize converges to zero. As a consequence, overdissipation occurs if the value of the prize is sufficiently small.

In this paper, we analyze the link between effort and preferences for redistribution. If individuals hold standard preferences, those with higher ability exert more effort. Higher effort leads to a higher income. Individuals with a higher income oppose redistribution. Yet, under non-standard preferences, the link between effort and redistribution is not clear-cut. If aversion to inequity is sufficiently strong, even individuals with high ability may support redistribution. In a lab experiment, we indeed find that participants with higher ability are willing to help the needy if earning income becomes more difficult for everybody. To check whether this finding is externally valid, we use data from the World Value Survey. We do not find a significant positive effect of preferences for effort on preferences for redistribution, but we also do not find the significant negative effect predicted by standard theory. Also, in the field, those who have to pay for redistribution are not more likely to be opposed than the recipients.

Researchers frequently studied the casual relationships of other-regarding preferences by applying experimental methods in bilateral settings (e.g., dictator game and ultimatum game). We use a framed experiment on taxes to study preferences for redistribution in a multi-person setting. We find presence of heterogeneous preferences with a substantial share of tax rate choices in line with both payoff maximization and other-regarding preferences. Notably, our data is not consistent with inequality aversion but points to other forms of other-regarding preferences, as fairness and altruism. By manipulating how subjects are assigned to a given level of pre-tax income, we vary the individual entitlements. We find a difference in the willingness to redistribute income when comparing the treatment where pre-tax income is assigned by relative performance in a production task (a general knowledge quiz) to the treatment where pre-tax income is assigned by luck. We do not find any significant difference in comparison to the intermediate treatment where pre-tax income is assigned by a combination of luck and performance. The perception of a fair tax is different depending on whether subjects' pre-tax income is below or above average, which is in line with a fairness bias. Finally, subjects not knowing whether their pre-tax income is below or above the average when choosing the tax rate behave as if they were more other-regarding.

Gender, income, education and self-employment are robust predictors for individual support for redistribution in the OECD. In addition, considerations of social status, the fairness of the allocation mechanism, perceived moral worth of the poor and individual autonomy are important. The results for the OECD are compared to those for a large sample of non-OECD countries which also include less developed economies. Neither gender, nor self-employment, nor fairness considerations exhibit a robust association with preferences for redistribution. However, education, income, individual autonomy and moral worth of the poor remain important determinants. On average, preferences for redistribution indicate that within the OECD, there is no desire to change redistributive policies. In contrast, in the sample of non-OECD countries, on average there is a desire to redistribute less.

Although both economists and psychologists seek to identify determinants of heterogeneity in behavior, they use different concepts to capture them. In this review we first analyze the extent to which economic preferences and psychological concepts of personality - such as the Big Five and locus of control - are related. We analyze data from incentivized laboratory experiments and representative samples and find only low degrees of association between economic preferences and personality. We then regress life outcomes - such as labor market success, health status and life satisfaction - simultaneously on preference and personality measures. The analysis reveals that the two concepts are rather complementary when it comes to explaining heterogeneity in important life outcomes and behavior.

We conduct a classroom survey to investigate the willingness to sacrifice consumption in absolute terms in order to ascend above others in terms of consumption levels. In contrast to other studies using survey methodologies, participants are divided into a treatment and a control group. This allows us to distinguish whether choosing less in absolute terms is really induced by relative consumption concerns, or else by nonmonotonic preferences. We find that relative consumption concerns provide a good explanation for choosing less in the case of some goods, while this is not the case for a number of other goods.

Robert Sugden has recently elaborated upon the case for a normative standard of freedom as opportunity that is supposed to cope with the problem of how to realign normative economics - with its traditional rational choice orientation - with behavioral economics. His standard, though, presupposes that people respond to uncertainty about their own future preferences by dismissing any kind of self-commitment. We argue that the approach lacks psychological substance: Sugden's normative benchmark - the responsible person - is a purely artificial construct that can hardly serve as a convincing role model in a contractarian setting. An alternative concept is introduced, and some policy implications are briefly discussed.

While research on subjective well-being abounds, comparatively little thought has been given to its practical policy implications. Two approaches to derive policy advice have emerged in the literature: One is organized in terms of the idea to maximize a hedonic social welfare function, the other focuses on the design of constitutional rules to facilitate the individuals' self-determined pursuit of happiness. We suggest to substantiate what it means to pursue happiness, in particular by drawing upon a psychologically informed account of preference learning. If extended in this direction, a notion of the pursuit of happiness has interesting practical policy implications.

This paper reconsiders the division of the literature on electoral competition into models with forward-looking voters and those with backward-looking voters by combining ideas from both strands of the literature. As long as there is no uncertainty about voters’ policy preferences and parties can commit in advance to a policy platform but not to a maximal level of rent extraction, voters can limit rents to the same extent as in a purely backward-looking model. At the same time, the policy preferred by the median voter is implemented as in a standard forward-looking model of political competition on an ideological policy dimension. Voters achieve this outcome by following a simple lexicographic voting strategy. They cast their vote in favor of their preferred policy position, but make their vote dependent on the in-cumbent parties’ performance in office whenever they are indifferent. When uncertainty about the bliss point of the median voter is introduced into the model, voters have to accept higher rent payments, but they still retain some control over rent extraction.

The present paper analyzes intergenerational correlations in leisure time use between parents and their adult children in order to gain an understanding of the importance of genetics and early childhood learning mechanisms in preference formation. Data from the British Household Panel Survey (BHPS) is used to regress time use choices of children on the behavior of their parents after the former have left to form their own household. A principal component analysis on eight time use items reveals two identifiable components, associated with personal leisure time use outside the home, and voluntary work. Estimations find substantial and significant correlations for both components, but suggest that the variance in filial behavior explained by the variance in parental behavior is limited, ranging from 17% to 32% for personal leisure time use, and from 2% to 7% for voluntary work. Moreover we provide evidence that direct transmission of parental preferences to their children accounts for roughly 20% of the observable similarity between the two generations. These results are robust to a wide array of robustness checks, including changes in estimation technique, model specification, and data restrictions, and suggest that these correlations can be ascribed to preference transmission from parental to filial generation rather than to coordination between generations. Aside from adding to the growing economic literature on preference transmission models, it also provides empirical support for the strong impact of non-parental sources of preferences formation, voiced particularly in models of dual inheritance.

This paper describes individuals' inequality perceptions, distributional norms, and redistributive preferences in a panel of OECD countries, primarily focusing on the association between these subjective measures and the effective level of inequality and redistribution. Not surprisingly, the effective level of redistribution (after tax-and-transfer inequality) is positively (negatively) correlated with redistributive preferences. There is also evidence showing that the subjective and objective dimension of inequality and redistribution are, at least partially, linked with individuals' political preferences and their voting behavior. The association between objective and subjective measures of inequality and redistribution vanishes, however, once more fundamental country characteristics are taken into account. This suggests that these characteristics explain both redistributive preferences as well as the effective level of redistribution and after tax-and-transfer inequality.

With a sample of 700 future public sector primary teachers in India, a Discrete Choice Experiment is used to measure job preferences, particularly regarding location. General skills are also tested. Urban origin teachers and women are more averse to remote locations than rural origin teachers and men respectively. Women would require a 26-73 percent increase in salary for moving to a remote location. The results suggest that existing caste and gender quotas can be detrimental for hiring skilled teachers willing to work in remote locations. The most preferred location is home, which supports decentralised hiring, although this could compromise skills.

To assess whether and when the equation economic growth = better life holds, it is necessary to understand what human motivations drive the economic growth process. The preference subjectivism of canonical welfare economics is of little help here as it treats the motivations underlying individual behavior as an unexplained black box. The present paper therefore reviews several motivational hypotheses suggested by biology, behavioral science, and cognitive psychology. They point to a strong influence of cognitive and noncognitive learning processes on the underlying motivations or, in economic terminology, the emergence and change of individual preferences. As a consequence, subjective welfare assessments tend to follow a drift process once a certain level of prosperity has been accomplished by economic growth. The normative relevance of the resulting preference relativism is argued to be particularly momentous, if the value basis of normative judgments is extended beyond the welfare criterion to justice and fairness considerations.

The time devoted to housework in couple households is substantial. Research on intrahousehold time allocations has generally assumed that housework is a necessary evil and that the partner with the lower opportunity cost of time in the market will devote more time to home production. In reality, households/individuals are likely motivated to maximize happiness, and preferences regarding even mundane household chores differ considerably. We use information on preferences, opportunity costs, and time use from the 2000-2001 United Kingdom Time Use Survey to examine the time partners spend doing laundry, ironing, cleaning, and food shopping. While compared with other household chores such as gardening and do-it-yourself repairs, the selected activities are generally less enjoyable, preferences do vary across the population and are correlated with reported time use. Joint multivariate analysis of his and her time on weekend and weekday days as well as maid service reveals that her opportunity cost of time matters substantially more than his, but that his preferences play a greater role than hers.

This paper analyzes the extent to which intergenerational upward and downward mobility in earnings are related to individuals' preferences for redistribution. A novel survey question from the German Socio-Economic Panel Study - whether the taxes paid by unskilled workers are too high, adequate or too low - are used to elicit attitudes toward redistribution. Intergenerational mobility with regard to long-term earnings is measured using a rich panel data spanning an observation window of 22 years. The results reveal that intergenerational mobility is significantly related to preferences for redistribution. The empirical results yield strong and robust support for Piketty's (1995) rational-learning theory: individuals who experience upward (downward) intergenerational mobility are less (more) likely to favor redistribution taxation policies.

With a sample of 700 future public sector primary teachers in India, a Discrete Choice Experiment is used to measure job preferences, particularly regarding location. General skills are also tested. Urban origin teachers and women are more averse to remote locations than rural origin teachers and men respectively. The joint analysis of preferences and skills suggests that existing caste and gender quotas are detrimental for the objective of hiring skilled teachers willing to work in remote locations. The most preferred location is home, which supports decentralised hiring, although evidence suggests that in remote areas this could compromise skills.

A small committee has to approve/reject a project with uncertain return. Members have different preferences: some are value-maximizers, others are biased towards approval. We focus on the efficient use of scarce information when communication is not guaranteed, and we provide insights on the optimal committee composition. We show that the presence of biased members can improve the voting outcome by simplifying the strategies of unbiased members. Thus, heterogeneous committees perform at least as well as homogeneous committees. In particular, when value-maximizers outnumber biased members by one vote, the optimal equilibrium becomes unique. Finally, allowing members to communicate brings no improvement.

Son preference is widespread in a number of developing countries. Anecdotal evidence suggests that women may contribute to the persistence of this phenomenon because they derive substantial long-run non-monetary benefits from giving birth to a son in the form of an improvement in their intra-household position. This paper tests this hypothesis in the Indian context. The results suggest that for the most part there is little evidence of substantial female benefits, and any positive impacts of having a son disappear after six months. This implies that the female-specific self-interest in a son is probably much lower than commonly assumed.

Available online 15 October 2013. We study how the distribution of other-regarding preferences develops with age. Based on a set of allocation choices, we classify each of 717 subjects, aged 8 to 17 years, as either egalitarian, altruistic, or spiteful. We find a strong decrease in spitefulness with increasing age. Egalitarianism becomes less frequent, and altruism much more prominent, with age. Females are more frequently classified as egalitarian than males, and less often as altruistic. By varying the allocation recipient as either an in-group or an out-group member, we also study how parochialism develops with age. Parochialism emerges significantly in the teenage years.

We study a matching model with heterogeneous agents, nontransferable utility and search frictions. Agents differ along a horizontal dimension (e.g. taste) and a vertical dimension (e.g. income). Agents’ preferences coincide only in the vertical dimension. This approach introduces individual preferences in this literature as seems suitable in applications like labor markets (e.g. regional preferences). We analyze how the notion of assortativeness generalizes to integration or segregation outcomes depending on search frictions. Contrary to results from the purely vertical analysis, here, agents continuously adjust their reservation utility strategies to changing search frictions. The model is easily generalizable in the utility specification, the distribution of taste-related payoffs and the number of vertical types. Extreme utility specifications can be treated as a case of horizontal heterogeneity only.

In recent decades, the immigration of workers and refugees to Europe has increased substantially, and the composition of the population in many countries has consequently become much more heterogeneous in terms of ethnic background. If people exhibit in-group bias in the sense of being more altruistic to one's own kind, such increased heterogeneity will lead to reduced support for redistribution among natives. This paper exploits a nationwide program placing refugees in municipalities throughout Sweden during the period 1985{94 to isolate exogenous variation in immigrant shares. We match data on refugee placement to panel survey data on inhabitants of the receiving municipalities to estimate the causal effects of increased immigrant shares on preferences for redistribution. The results show that a larger immigrant population leads to less support for redistribution in the form of preferred social benefit levels. This reduction in support is especially pronounced for respondents with high income and wealth. We also establish that OLS estimators that do not properly deal with endogeneity problems - as in earlier studies - are likely to yield positively biased (i.e., less negative) effects of ethnic heterogeneity on preferences for redistribution.

We assess the empirical validity of the overall theoretical framework of other-regarding preferences by focusing on those preference axioms that are common to all the prominent theories of outcome-based other-regarding preferences. This common set of preference axioms leads to a testable implication: the strict preference ranking of self over a finite number of alternatives lying on any straight line in the space of material payoffs to self and other will be single-peaked. The extent of single-peakedness varies from a high of 79% to a low of 54% across our treatments that are based on dictator and trust games. Positively and/or negatively other-regarding subjects are significantly less likely to report single-peaked rankings relative to self-regarding subjects. We delineate the potential reasons for violations of single-peakedness and discuss the implications of our findings for theoretical modeling of other-regarding preferences.

Following the report of the Stiglitz Commission, measuring and comparing well-being across countries has gained renewed interest. Yet, analyses that go beyond income and incorporate non-market dimensions of welfare most often rely on the assumption of identical preferences to avoid the difficulties related to interpersonal comparisons. In this paper, we suggest an international comparison based on individual welfare rankings that fully retain preference heterogeneity. Focusing on the consumption-leisure trade-off, we estimate discrete choice labor supply models using harmonized microdata for 11 European countries and the US. We retrieve preference heterogeneity within and across countries and analyze several welfare criteria which take into account that differences in income are partly due to differences in tastes. The resulting welfare rankings clearly depend on the normative treatment of preference heterogeneity with alternative metrics. We show that these differences can indeed be explained by estimated preference heterogeneity across countries - rather than demographic composition.

The current level of competition in European commercial passenger rail markets is low and empirical data on customer preferences in intramodal competition has hardly been available, yet. Our study raises the knowledge of competition in commercial passenger rail by exploring the determinants of customers' choice behaviour on two cross-border routes, Cologne-Brussels and Cologne-Amsterdam. We analyse stated preference information from about 700 on-train interviews by means of multinomial Logit regressions. Our analysis indicates that customers experiencing competition (Cologne-Brussels) show a higher preference for competitive services than customers for whom competition is a purely hypothetical situation (Cologne-Amsterdam). Moreover, travellers show a status quo bias, i.e. a preference for the service provider on whose trains they were interviewed which partly stems from switching costs. These findings regarding status quo bias and switching costs complement previous studies on the outcome of intramodal competition, implying that entry is even more difficult than they predicted.

Contemporary mainstream normative economists assess policies in terms of their capacities to satisfy preferences, though most would concede that other factors such as freedom, rights, and justice are also relevant. Why should policy be responsive to preferences? This essay argues that the best reason is that people's preferences are in some circumstances good evidence of what will benefit them. When those circumstances do not obtain and preferences are not good evidence of welfare, there is little reason to satisfy preferences.

A common feature of the literature on the evolution of preferences is that evolution favors nonmaterialistic preferences only if preference types are observable at least to some degree. We argue that this result is due to the assumption that in each state of the evolutionary dynamics some Bayesian Nash equilibrium is played. We show that under unobservability of preference types, conditional on selecting some self-confirming equilibrium as a rule for mapping preference into behavior, non-selfish preferences may be evolutionarily successful.

While there is little doubt that innovations drive economic growth, their effects on well-being are less clear. One reason for this are ambivalent effects of innovations on well-being that result from pecuniary and technological externalities of innovations, argued to be inevitable. Another major reason lies in the fact that, as a result of innovations, preferences can change over time. Under such conditions, a time-consistent measuring rod for changes in well-being is hard to construct. Existing conceptions of well-being are shown not yet to solve the problem in a way that provides an unambiguous answer to the question in the title.

A robust feature of models of electoral competition between two opportunistic, purely office-motivated parties is that both parties become indistinguishable in equilibrium. I this short note, I show that this strong connection between the office motivation of parties and their equilibrium choice of identical platforms depends on the following two - possibly counterfactual - assumptions: 1. Issue spaces are uni-dimensional and 2. Parties are unitary actors whose preferences can be represented by expected utility functions. The main goal here is to provide an example of a two-party model in which parties offer substantially different platforms in equilibrium even though no exogenous asymmetries are assumed. In this example, some voters' preferences over the 2-dimensional issue space are assumed to exhibit non-convexities and parties evaluate their actions with respect to a set of beliefs on the electorate.
