The decomposition of national CAPM market betas of European countries’ value and growthnportfolio returns into cashflow and discount rate news driven components reveals that i) highnaverage returns on value portfolios are associated with disproportionately high sensitivity to national cashflow news which corroborates recent evidence for the U.S. and ii) two-beta variants of national CAPMs capture the cross-sectional dispersion in European stock returns. The latter finding is suggestive of relatively well integrated stock markets among the core European countries and reflects basic asset pricing theory. One (national) discount factornshould price any (international) asset.

After several decades of academic research on the contingent valuation (CV) method a consistent behavioral explanation of 'hypothetical bias' is still lacking. Based on evidence from economics, economic psychology and the political sciences, I propose an explanation that is based on two simple working hypotheses about respondent behaviour in contingent valuation surveys. The first hypothesis is that survey respondents are unable to form consistent preferences about unfamiliar goods unless the choice context offers reliable, informative cues that can be rationally exploited in simplified heuristics. The second hypothesis is that the probability and impact of strategic responses in dichotomous-choice questions about public goods depends on the extent to which the presented hypothetical costs differ from the actual costs. The literature on hypothetical bias is revisited in the light of these behavioral hypotheses. I find that the hypotheses are generally supported by the empirical data. Moreover, the hypotheses are able to explain several important empirical phenomena that previous research has not been able to explain. In particular, they solve the puzzle that pre-election polls, but not CV surveys, are able to predict actual referendum outcomes, and they explain why income effects on willingness to pay are lower in CV responses than in actual votes. If confirmed by further studies, the hypotheses will have important implications for future research and practice. First, the hypothetical costs presented in the dichotomous choice question should to be close enough to the actual costs to be credible to all respondents. This can be achieved by specifying the costs as a percentage (rather than absolute) change in taxes. Second, the respondents should be given the option to answer based on information about the positions of large parties and interest groups with known political orientation rather than based on the raw policy information. Theory and evidence suggest that this new survey paradigm largely eliminates the fundamental problems of the conventional stated preference methods.

Temporary fluctuations of the U.S. consumption-wealth ratio, cay, predict excess returns onninternational stock markets at the business cycle frequency. This finding is the reflection of a common, temporary component in national stock markets. Exposure to this common component explains up to 60 percent of the covariation among long-horizon returns on the G7nstock markets for the time period from 1973 to 2005. The impact of the common componentnon stock market comovement is particularly pronounced in the period from 1990 to 2005.

High parental income, while undeniably causing beneÞts for a child in terms of better access to education and more favorable labor market outcomes, may at the same time increase a childÕs income aspirations and thereby reduce Þnancial satisfaction, ceteris paribus. In this paper, we investigate the relationship between Þnancial satisfaction and parental income with data from the German Socio-Economic Panel. The results indicate that there is indeed a negative well-being externality of parental income, and that children appear to compare their actual income situation with the aspiration level acquired while growing up.

This paper examines the role of simplified heuristics in the formation of preferences for public goods. Political scientists have suggested that voters use simplified heuristics based on the positions of familiar parties to infer how a proposed policy will affect them and to cast a vote in line with their interests and values. Here, we use a two-stage field-survey experiment to investigate how knowledge of party positions affects policy choices. We followed standard procedures in developing an attribute-based choice experiment on alternative land-use policies in Switzerland. In contrast to the usual formulation, however, the hypothetical costs of the proposed policies were formulated as a percentage change in taxes. The benefit of this formulation relative to the usual absolute money amounts is that the credibility of the (hypothetical) costs for respondents does not depend on respondent income. Furthermore, the formulation allowed us to solicit party positions on the proposed policies. Six out of eight contacted parties provided their positions. We then conducted a split-sample mail survey where we included a table of the party positions with a sub-sample of the questionnaires. We report six main experimental results. (1) The response rate of the survey was unaffected by the party positions. (2) The proportion of no-choice answers was decreased by forty percent relative to the control. (3) The party information significantly affected the choices directly and in interaction with respondents’ general attitudes towards public spending for nature and landscape conservation and thus affected the way how individuals mapped from general attitudes to preferences for specific policies. (4) The information interacted with educational level in only eight out of forty choice sets, suggesting that even the more educated relied on simplified heuristics. (5) Respondents who knew the party positions were more sensitive to the tax attribute. (6) For respondents with medium and higher tax bills, the resulting willingness-to-pay estimates were decreased by a factor of two to ten relative to the control. These findings suggest that the party information helped the respondents to articulate more consistent preferences than in the treatment without the party information.

Wir untersuchen die Struktur der Verwaltungs- und Verfahrenskosten der öffentlichen Unfallkassen in Deutschland. Als Datengrundlage dienen die Zahlen aus den Geschäfts- undnRechnungsergebnissen der Unfallträger der öffentlichen Hand für die Jahre 1998 bis 2005. Die Ergebnisse einer Regressionsanalyse liefern Aufschlüsse über Kostentreibernund Skaleneffekte. Die Verwaltungs- und Verfahrenskosten konnten durchnmeldepflichtige Unfälle in der Allgemeinen und Schülerunfallversicherung sowie die Präventionsintensität der Unfallkassen sehr gut erklärt werden.nDie Arbeit hat drei Hauptergebnisse. Erstens sind die Unfallkassen sehr heterogennbezüglich ihrer Verwaltungs- und Verfahrenskosten. Zweitens haben diese Kostenunterschiede nichts mit der Größe der Unfallkassen zu tun: es kann keinerlei Evidenz für Kostenvorteile größerer Unfallkassen (Skaleneffekte) gefunden werden. Drittens ziehen Schülerunfälle erheblich geringere Kosten in der Verwaltung nach sich als Unfälle in der Allgemeinen Unfallversicherung. Ferner gibt es Hinweise, dass eine höhere Präventionsintensität einer Unfallkasse auch höhere Kosten in der Verwaltung nach sich zieht.

Idiosyncratic consumption risk explains more than 60 percent of the cross-sectional variation in quarterly exchange rate changes and currency returns. Our results are obtained from data of 13 industrialized countries and arenbased on an international version of the consumption capital asset pricing model (CCAPM) in which we account for international consumption heterogeneity. We use this framework to dissect the consumption-exchange rate anomaly, the empirical fact that international variation in purchasing power alone does not appear to account for differences in consumption growth rates across countries. As an explanation for this phenomenon, we explore the presence of currency risk premia that also lead to departures from uncovered interest parity (UIP). We decompose the cross-sectional variation in consumption into one component that is due to cross-country differences in inflation rates and a second component that is due to international variation in nominal interest rates. We interpret these factors as indicators of goods and financial market segmentation respectively. We find that bothnhelp account to virtually equal parts for the cross-section of exchange rate changes. Interestingly, the price of aggregate consumption risk has declined over the 1990s, in line with a growing literature that documents a growingninternationalisation of country portfolios over this period.

Quality of life factors continue to gain importance in residential location decisions as well as location decisions of firms. One such factor is an attractive local landscape. The aim of this paper is to provide a survey of the empirical literature on the role of landscape amenities in local economic change. Following common amenity definitions, we define landscape amenities as landscape features that are location-specific, latent non-market input goods that directly enter residents’ utility functions. Using this definition we identify thirty-nine relevant studies that use either migration or regional economic models or hedonic pricing techniques. One result from the analysis of migration and regional economic studies is that intra-country migrants were attracted by amenities about as frequently as by a low tax burden. Effects of amenities on employment and income are less well established. However, many of these studies used rather limited amenity variables. The results from hedonic studies show that a wide variety of local amenity attributes are partly capitalized in housing prices and that studies on a larger geographic scale are more likely to identify a significant a role of amenities. Newly available land cover datasets and spatial analysis tools have the potential to overcome important data limitations of many earlier studies. Future research may thus contribute to a better understanding of the role of landscape amenities in economic change and to a better coordination of regional and environmental policies.

This paper deals with the identification of treatment effects when the outcome variable is ordered. If outcomes are measured ordinally, previously developed methods to investigate the impact of an endogenous binary regressor on average outcomes cannot be applied as the expectation of an ordered variable, in its strict sense, does not exist, and a shift in focus to distributional effects is indispensable. Without imposing a fully fledged parametric model the treatment effects are generally not point-identified. Assuming a threshold crossing model on both the ordered potential outcomes and the binary treatment variable leaving the distribution of error terms and functional forms unspecified, it is discussed how the treatment effects can be bounded and inference on the bounds can be conducted.

Deterrence has been a crucial element in fighting terrorism, both in politics and in rational choice analyses of terrorism. However, there are two strategies that are superior to deterrence. The first one is to make terrorist attacks less devastating and less attractive to terrorists through decentralization. The second one is to raise the opportunity cost – rather than the material cost – for terrorists. These alternative strategies will effectively dissuade potential terrorists. It is here argued that they not only apply to society as a whole but can also usefully be applied by business enterprises.
