Based on the constructionist point of view applied to Subjective Well-Being (SWB), five hypotheses were advanced about the predictive power of the top-down effects and bottom-up processes over a five years period. The sample consisted of 297 respondents, which represent the Italian sample of a European longitudinal survey; the first phase was conducted in 1995 and the follow-up in 2000. Satisfaction judgments were collected on Overall Life Satisfaction (OLS) and on seven Life Facet Satisfaction (LFS) domains. The top-down effects were measured using a method derived from the constructionist point of view. Life conditions, which represent the bottom-up processes, were gathered by structured questionnaire and were optimized by a factor analyses. A stepwise regression was performed in each satisfaction judgment to test the five hypotheses, which were confirmedwith only few exceptions. The results revealed that the top-down effects were a significant predictor in all satisfaction judgments, especially in OLS, where it was the strongest predictor. Life conditions (bottom-up factors) were less strong predictors than the top-down effects, but they became strong predictors if they were gathered at the same time as satisfaction judgments. 相似文献

Interregional migration and labor market imbalances 总被引:1,自引:0,他引:1
This paper investigates the effects of internal migration in developed countries on widening wage inequality and high unemployment, and it addresses the geographical dimension of both problems. A two-region dynamic model is developed, which accounts for the skill composition of recent internal migration flows; it also innovates on the existing literature on migration by introducing capital-skill complementarity in the production function. The main conclusion is that migration can actually aggravate labor market imbalances. In a competitive set-up, migration temporarily amplifies the geographical dispersion of unskilled workers wages and raises the average wage premium of the economy. When wage rigidities are introduced, labor mobility increases regional dispersion of unskilled workers employment. In the short-run it may even reduce the total employment of the economy.A previous version of this paper circulated with the title Migration Flows and Interregional Labor Market Disequilibrium.

We consider the optimal determination of family allowances in a model where some of the parents have higher ability to raise children than others. First-best policy gives both types of parents the same level of utility. If neither parental ability nor parental actions are fully observable, however, the policy maker has to take into account the incentive-compatibility constraint that more able parents should not find it profitable to mis-represent their true ability by investing less in their children, and having a lower number of children. The second-best policy induces more able parents to have the first-best number of children, and to invest in each child at the first-best level. Less able parents are induced to have fewer children than in first best, and will underinvest in each child. Whether the government should subsidize more the more able parents, or the less able ones, depends on the properties of the cost function. In second best, however, less able parents will end up with lower utility than more able parents whatever the cost function.All correspondence to Annalisa Luporini.

This paper considers a decision-making process under ambiguity in which the decision-maker is supposed to split outcomes between
familiar and unfamiliar ones. She is assumed to behave differently with respect to unfamiliar gains, unfamiliar losses and
customary (familiar) outcomes. In particular, she is supposed to be pessimistic on gains, optimistic on losses and ambiguity
neutral on the familiar outcomes. A generalization of the usual Choquet Integral is formalized when the decision maker holds
capacities and probabilities. A characterization of the decision-maker’s behavior is provided for a specific subset of capacities,
in which it is shown that the decision-maker underestimates the unfamiliar outcomes while is linear in probabilities on customary
ones. 相似文献

AbstractTraditional unit root tests display a tendency to be nonstationary in the case of structural breaks and nonlinearity. To eliminate this problem this paper proposes a new flexible Fourier form nonlinear unit root test. This test eliminates this problem to add structural breaks and nonlinearity together to the test procedure. In this test procedure, structural breaks are modeled by means of a Fourier function and nonlinear adjustment is modeled by means of an exponential smooth threshold autoregressive (ESTAR) model. The simulation results indicate that the proposed unit root test is more powerful than the Kruse and KSS tests. 相似文献
