The voluntary provision of a pure public good is studied in the presence of an anonymous external donor. New data generated using experimental procedures employing both extra-credit and cash incentives, as well as asynchronous access to real-time decision rounds lasting several days, are compared to previous data generated using traditional cash-only, synchronous-access laboratory procedures. The effect on resource allocations to the public good of introducing external matching funds is examined in two different settings, lump-sum matching and one-to-one matching. The new data confirm the robustness of results previously reported in Baker et al. (2009) to the change in laboratory procedures and incentives. The new data are then used to extend the parameter space in which the two matching mechanisms are studied, including: varying within-round information regarding the current level of public-good allocations and varying group size from four to twenty group members. Allocations in lump-sum matching are no worse, and sometimes better, than one-to-one matching in these new treatments. 相似文献

哈特的重要贡献是,在一般法理论中提出并引入了内在视角。内在视角包含行为模式的趋同与批判反思态度这两个关键因素。批判反思态度既有一种认知维度,又有一种意志要素。通过与外在视角的坐标对照,可以确定内在视角是实践参与者的内在化视角,它与哈特自身的理论立场存在一定的联系与区别。内在视角的引入,有助于说明和理解法律规范性并建构一种有关法律陈述的语义学。此外,内在视角还应被视为法理学的方法论基调。 相似文献

Utilizing Norwegian linked register and survey data, while exploiting a discontinuity in public sick pay legislation, I show that the public sick pay compensation level causally affects male performance pay workers' sick leave days. Both male and female performance pay workers experience longer sick leaves when provided private supplementary sick pay compared with those being eligible for public sick pay only. This differential impact of the replacement rate on workers' sick leave rates reveals heterogeneous behavioural changes following public sick pay cuts, and this heterogeneity will be reinforced by the provision of employer‐provided sick pay to attractive worker groups. 相似文献

Social security policy with public debt in an aging economy 总被引:1,自引:0,他引:1

This paper analyzes a social security policy with public debt in an overlapping generations growth model. In particular,
the paper considers a situation in which population aging causes a heavy burden of social security payments where public debt
is issued by the government to finance the payment. In the model presented below, an economy with an aging population may
achieve two dynamically inefficient equilibria. Under certain conditions, the effects of pension reform and population aging
on capital accumulation are entirely different between the two equilibria.

This study looks at compensating differentials in the National Longitudinal Survey of Youth (NLSY) to derive estimates of the levels of time preference for labor force participants in each of 15 waves of data from 1979 to 1994. With these estimates the evolution of time preference over the life course is described. Future utility among labor force participants appears to be valued more highly by subjects who are older, more schooled, white, or male. Controlling for schooling level, a higher IQ is associated with a preference for more immediate rewards.If social rates of time preference are correlated with individual rates of time preference then population aging could create intergenerational asymmetries in the social rate of time preference.This phenomenon could make the optimal investments of young populations appear selfish to future generations that are older.Support from Hopkins Population Center (R24) is gratefully acknowledged. I am thankful for helpful comments received from Jim Burgess, Mike Grossman, Bruce Hamilton, Fritz Laux, Athanasios Orphanides, Katie Roche, and Eric Slade. All errors are my own.

This paper revisits the literature on overlapping generations models in the demographic context of a continuous age distribution
and a general age schedule of mortality. We show that most of the static results known for the 3 or N age-group models can be extended to the continuous model. Some results, previously established for economies without capital,
are extended to productive economies. We also make some progress on the existence of some steady states as well as on the
dynamic properties.

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.

To understand the role of evidence in tax policy design, this paper organizes the empirical analysis of reform under five loosely related headings: (i) key margins of adjustment, (ii) measurement of effective tax rates, (iii) the importance of information and complexity, (iv) evidence on the size of responses, and (v) implications from theory for tax design. The context for the discussion is the recently published Mirrlees Review of tax reform. Although the Review focused on all aspects of tax reform, this paper highlights the taxation of earnings. It also comments on earnings taxation in the context of VAT base‐broadening reforms and the taxation of capital. 相似文献

In this study, the value of nonmarket time is estimated for American families using the opportunity cost approach whereby the market wage is taken as a measure of the value of time and used to impute nonmarket income to each household. In cases where the market wage is not observed, a new estimation technique is used to obtain consistent estimates of the wage. It is shown that the nonmarket income of families increases with family money income and family size, but decreases with age and the number of job holders in the family. The implications for taxation are discussed. 相似文献
