In this paper we show that the macroeconomic effects of demographic changes strongly depend on the degree of altruism and on the specification of the intertemporal utility function. We allow for agents either to be altruistic in the sense of Barro (1974) or non-altruistic. In the latter case, generations are heterogeneous like in the „unloved children” model of Weil (1989). In the former case, where the model is a standard Ramsey model with identical agents, we distinguish a Millian and a Benthamite intertemporal utility function. For each of these models, we study the effects of an anticipated and unanticipated permanent decline in population growth as well as the consequences of a baby-boom/baby-bust scenario.

We simulate the effect of the introduction of premium differentiation (experience rating) in the Dutch Unemployment Insurance system on the demand for labor for a variety of sectors in the Dutch economy. For the simulations we use the Bentolila and Bertola (1990) framework as a point of departure. In the simulations, the introduction of experience rating is modeled as expenditure neutral: in the absence of premium differentiation the cost of financing UI is modeled as a wage tax (independent of the number of workers fired by the firm), whereas in the presence of experience rating this cost is attributed to firing cost (affected by the firing action). Thus, the introduction of experience rating results in a shift from wage cost to firing cost. Following the political debate on the issue in the Netherlands, we assume that the introduction of experience rating does neither lead to a change in tax rates paid by workers nor to a change in eligibility rules or replacement rates of benefit claimants. Specific attention is paid to the distinction between young and old workers . In the model, labor adjustment costs (hiring and firing costs) are linear. The model allows for uncertainty in the business cycle.All correspondence to Hans Bloemen. Responsible editor: Alessandro Cigno  相似文献

Recent literature finds that in OECD countries the cross-country correlation between the total fertility rate and the female labor force participation rate, which until the beginning of the 1980s had a negative value, has since acquired a positive value. This result is (explicitly or implicitly) often interpreted as evidence for a changing sign in the time-series association between fertility and female employment within OECD countries. This paper shows that the time-series association between fertility and female employment does not demonstrate a change in sign. Instead, the reversal in the sign of the cross-country correlation is most likely due to a combination of two elements: First, the presence of unmeasured country-specific factors and, second, country-heterogeneity in the magnitude of the negative time-series association between fertility and female employment. However, the paper does find evidence for a reduction in the negative time-series association between fertility and female employment after about 1985.I benefited from stimulating discussions with Arnstein Aassve, Pau Baizan, Francesco Billari, Henriette Engelhardt, Hans-Peter Kohler and Alexia Prskawetz and a seminar in Rostock.

Even though second generation immigrants make up ever increasing population shares in industrialized countries we know little about their social integration and wellbeing. This study focuses on the educational attainment of German born children of immigrants. Their schooling success still lags behind that of natives. This paper investigates school attendance and completed degrees of second generation immigrants and finds that even after controlling for characteristics the educational gap remains large and significant. The available evidence suggests that this group as a whole does not assimilate to native educational standards and instead increasingly falls behind.This research was completed while the author was guest at the Institute for the Study of Labor (IZA) in Bonn, Germany.

This paper analyses the effects of expected earnings and local markets conditions on the behaviour of young adults with high school diplomas. Decisions to either remain in the parental home or form a new household are modelled jointly with those of either gaining work experience or investing in a university education. Expected lifetime earnings are found to play a crucial role in determining the choice of studying and residing with parents. Poor labour market opportunities discourage young people from working and induce them to study. The cost of housing greatly influences the choice of working and leaving the parental home.

We examine the role of altruism in determining optimal transfers from a principal (a mother) to selfish agents (her children) in return for attention services. Transfer-attention contracts are studied in a setting in which informational asymmetries arise from the inability of a parent to determine the extent of her children's selfishness. We find a predominating exchange motive for transfers in the symmetric informational regime we study. However, both altruism and exchange are important motives under asymmetric information. We show that altruism facilitates transfer-attention exchange arrangements with certain trade partners under incomplete information, but diminishes trade with others.

In the paper the problem of nonlinear unbiased estimation of expectation in linear models is considered. The considerations are restricted to linear plus quadratic estimators with quadratic parts invariant under a group of translations. The one way classification model is considered in detail, for which an explicit formula for the locally best estimators is presented. A numerical evaluation of variances of the best estimators is given for some unbalanced one way classification models and compared with the variance of the ordinary linear estimators.  相似文献

There is strong public opposition to increased immigration throughout Europe. Given the modest economic impacts of immigration estimated in most studies, the depth of anti‐immigrant sentiment is puzzling. Immigration, however, does not just affect wages and taxes. It also changes the composition of the local population, threatening the compositional amenities that natives derive from their neighborhoods, schools, and workplaces. In this paper we use a simple latent‐factor model, combined with data for 21 countries from the 2002 European Social Survey (ESS), to measure the relative importance of economic and compositional concerns in driving opinions about immigration policy. The ESS included a unique battery of questions on the labor market and social impacts of immigration, as well as on the desirability of increasing or reducing immigrant inflows. We find that compositional concerns are 2–5 times more important in explaining variation in individual attitudes toward immigration policy than concerns over wages and taxes. Likewise, most of the difference in opinion between more‐ and less‐educated respondents is attributable to heightened compositional concerns among people with lower education.  相似文献

Studies of the principal-agent relationship find that monetary incentives work in many instances but that they can also backfire. Various mechanisms for this failure have been examined (e.g., intrinsic motivation, image concerns). We posit that an aversion to being exploited, i.e., being used instrumentally for another’s benefit, can also cause incentives to fail. Using an experiment we find that compliance is lower for exploitative principals compared to neutral ones despite using the same contracts. To corroborate our results we show that surveyed “exploitation aversion” mediates this effect. Our results have implications for the design and implementation of incentives within organizations.  相似文献

We study the least-square regression learning algorithm generated by regularization schemes in reproducing kernel Hilbert spaces. A non-iid setting is considered: the sequence of probability measures for sampling is not identical and the sampling may be dependent. When the sequence of marginal distributions for sampling converges exponentially fast in the dual of a Hölder space and the sampling process satisfies a polynomial strong mixing condition, we derive learning rates for the learning algorithm.  相似文献
