Within the debate about the future of the welfare state a guaranteed social minimum income is often discussed as an alternative to the current social security system. One objection to such a proposal argues that a social minimum income lacks social acceptance and normative recognition. Starting from the thesis that the standard instruments of survey research have little to offer for giving a detailed account of the attitudes towards a social minimum, we deploy the more complex method of Factorial Survey Design. The study sample consists of 121 employed persons. Within the study, the focus is on the criteria used and the differentiations made when people are asked to evaluate a just minimum income. It can be shown that a uniform and flat-rate social minimum possesses less legitimacy than a transfer system that differentiates entitlements according to the beneficiaries relation to the employment sphere and certain need criteria. In addition, we find support for the idea of low income subsidies as suggested by the negative income concept. Though the results give evidence of the normative attraction of a social minimum, it is also apparent that the social judgments of the respondents are influenced by in the normative principles of the existing social security arrangements. 相似文献

THE EAST END, THE WEST END, AND KING'S CROSS: ON CLUSTERING IN THE FOUR-PLAYER HOTELLING GAME 总被引:1,自引:0,他引:1
We study experimentally a standard four-player Hotelling location game with a uniform density of consumers and inelastic demand. The pure strategy Nash equilibrium configuration consists of two firms located at one quarter of the "linear city," and the other two at three quarters. We do not observe convergence to such an equilibrium. In our experimental data we find three clusters. Besides the direct proximity of the two equilibrium locations, this concerns the focal midpoint. Moreover, we observe that whereas this midpoint appears to become more notable over time, other focal points fade away. We explain how these observations are related to best-response dynamics, and to the fact that the players rely on best-responses in particular when they are close to the equilibrium configuration. 相似文献

Within the literature on European integration there is a widespread assumption that Europe is in need of intensified and more effective supranational social policy cooperation. However, on the political level it is doubtful whether such measures are welcomed by the national electorates. This article addresses this issue empirically by asking whether there is public demand for promoting greater European welfare policy cooperation and what are the determinants of such a demand. The data source used is the Eurobarometer survey 2000. A number of hypotheses dealing with socio-structural differences, the effects of welfare regime types, the subjective evaluation of the integration process and the role of identity will be scrutinised. Overall, the results indicate that at the attitudinal 'grass root' level there is no unequivocal support for a European welfare responsibility and that some fundamental cleavages are present. It is the regional and cultural aspects, especially, which turn out to be having an effect and to be influencing future political conflicts. A common European welfare arrangement, therefore, cannot be regarded as a solution to the problems the European Union is facing; rather it will raise new and severe problems of finding social and political support. 相似文献

The working‐class is typically regarded as the driving force of welfare state development. Yet, some argue that the middle‐classes' beneficial involvement in the welfare state is crucial for its financial sustainability and popular legitimacy. Against this backdrop, we investigate how recent welfare state reforms in Germany which affect the status of the middle‐class are viewed and discussed by this group. Germany is a particularly interesting case because its welfare state is seen to be centred on the desires of the middle‐class, especially through its focus on status maintenance and horizontal redistribution over the life‐course. However, the move from status maintenance to minimum income support in unemployment provision and the strengthening of private old age provision challenge this assumption. Thus, we ask how the German middle‐class views the emerging abandonment of the principle of status maintenance and the shift from collective to individual responsibility. Based on qualitative material from focus groups, we find that individual responsibility is generally supported, but that the state is still assigned responsibility for providing basic levels of social security. Furthermore, for those groups seen as less capable of acting individually responsible (e.g. the poor or long‐term unemployed) the ‘inducement’ of – or assistance for – individually responsible behaviour by the state is demanded. Overall, while the principle of ‘individual responsibility’ seems to find some resonance among the middle‐class members interviewed, they still try to balance individual and collective responsibility. 相似文献

This paper is a longitudinal analysis of the impacts of spontaneous volunteerism on those who responded to emergency needs immediately following the September 11, 2001 terrorist attacks on the World Trade Center in New York City. Our qualitative study investigates the long-term implications for the volunteers who participated in a myriad of helping behaviors ranging from working on the bucket brigade to serving food to rescue workers to working as translators for victims’ families. This project consists of two waves of data collection. The first set of in-depth interviews with 23 volunteers was conducted in the weeks following the attacks in the fall of 2001. In the second wave of interviews over 3 years later, we interviewed 20 volunteers, nearly half of whom were original respondents in the first wave. Through our analysis, we found that taking action facilitated meaningful therapeutic recovery from feelings of victimization following the event. In addition to the apparent long-term impact on personal healing, the opportunity to volunteer had lasting impacts on self-concept that translated to significant changes in life choices. The second wave of research also reveals that the experience of action impacted the volunteers’ community sentiment by fostering new levels of identification with and affinity for members of their community. In addition, community response work in the aftermath of a disaster appeared to increase community engagement in non-disaster times. 相似文献

Companies often decide in favour of IT investments (especially IT infrastructure investments) only because these investments build the foundation for more lucrative follow-up investments. Those intertemporal interdependencies among IT projects have to be considered within the scope of a value-based IT portfolio management. Therefore, current literature suggests the use of real options analysis??and therefore the application of option pricing models such as the binomial model or the Black-Scholes model. Both models require a complete market. However, because IT projects are characterized by project specific risks, which cannot be duplicated on a capital market, the forthright application of these models is problematic. This issue has been addressed within the scope of the discrete binomial model so far. In this paper we transfer these findings to the Black-Scholes model. Furthermore, we apply this approach to a real case and illustrate how a correct consideration of project specific risks using the Black-Scholes model can affect investment decisions. 相似文献

We design experiments to jointly elicit risk and time preferences for the adult Danish population. Since subjects are generally risk averse, we find that joint elicitation provides estimates of discount rates that are significantly lower than those found in previous studies and more in line with what would be considered as a priori reasonable rates. The statistical specification relies on a theoretical framework that involves a latent trade‐off between long‐run optimization and short‐run temptation. Estimation of this specification is undertaken using structural, maximum likelihood methods. Our main results based on exponential discounting are robust to alternative specifications such as hyperbolic discounting. These results have direct implications for attempts to elicit time preferences, as well as debates over the appropriate domain of the utility function when characterizing risk aversion and time consistency. 相似文献

Using CPS data for the period 1979–2009, the wage dispersion of truck drivers (and subsets of the truck driving sample) is compared with the trends in wage dispersion of males economy‐wide. We find that truckers' wages experienced a decrease in inequality post‐deregulation, as expected given the literature on regulation's impact on the labor market. We also find that the wage dispersion for truckers is markedly different from males economy‐wide, providing evidence that the wage distribution of truck drivers has been dominated by the changing structure of the occupation post‐deregulation and largely immune to the factors that increased inequality for the aggregate labor market. 相似文献

We derive two types of Akaike information criterion (AIC)‐like model‐selection formulae for the semiparametric pseudo‐maximum likelihood procedure. We first adapt the arguments leading to the original AIC formula, related to empirical estimation of a certain Kullback–Leibler information distance. This gives a significantly different formula compared with the AIC, which we name the copula information criterion. However, we show that such a model‐selection procedure cannot exist for copula models with densities that grow very fast near the edge of the unit cube. This problem affects most popular copula models. We then derive what we call the cross‐validation copula information criterion, which exists under weak conditions and is a first‐order approximation to exact cross validation. This formula is very similar to the standard AIC formula but has slightly different motivation. A brief illustration with real data is given. 相似文献

Leadership often serves as an explanatory category for performance outcomes (i.e., failure and success). This process can strengthen or weaken leadership effectiveness, because contingent on their performance leaders may gain or lose follower endorsement — the basis of leadership. Drawing on the social identity analysis of leadership, we hypothesized that leader group prototypicality and performance information interact to predict followers' perceptions of leadership effectiveness. Because group prototypical leaders are more trusted by their followers, we hypothesized that group prototypical leaders are evaluated as more effective after failure information than non-prototypical leaders. In contrast, we predicted that both prototypical and non-prototypical leaders should receive similar evaluations of leadership effectiveness after success. We found support for our predictions in a scenario experiment, a cross-sectional field study, and a laboratory experiment. 相似文献
