After‐tax income inequality has risen since the mid‐1990s, as increases in market income inequality have not been offset by greater fiscal redistribution. We argue that the substantial increase in the diversity of consumer goods has mitigated mounting political pressures for redistribution. Within a probabilistic voting framework, we demonstrate that if the share of diversified goods in the consumption bundle increases sufficiently with income, then an increase in goods diversity can reduce the political equilibrium tax rate. Focusing on OECD countries, we find empirical support for both the model's micro‐political foundations and the implied relation between goods diversity and fiscal policy outcomes. 相似文献

Public sector associations have successfully developed and run employee health insurance pools for almost 30 years, providing members with savings and flexibility not available from commercial health insurance carriers. This article looks at the models, technical tools and governance philosophy that have contributed to their success in a very challenging business environment. 相似文献

We analyze in this paper how various forms of state intervention can impact microfinance institutions’ lending behavior. Using a simple model where entrepreneurs receive individual uncollateralized loans, we show that, not surprisingly, state intervention through the loan guarantee increases the number of entrepreneurs receiving a loan. However, after modeling business development services (BDS) provided by the microfinance institution, we show that the loan guarantee can have a counterproductive effect by reducing the number of entrepreneurs benefiting from such services. We therefore analyze an alternative policy: BDS subsidization. We show that if BDS are efficient enough and are targeted toward less performing borrowers, then—for fixed government expenditures—such subsidies do better in terms of financial inclusion than the loan guarantee. Moreover, we argue that—under similar conditions—BDS subsidization alone does better in terms of financial inclusion than a mix of policies. 相似文献

Long‐term insurance contracts are widespread, particularly in public health and the labor market. Such contracts typically involve monthly or annual premia which are related to the insured's risk profile. A given profile may change, based on observed outcomes which depend on the insured's prevention efforts. The aim of this paper is to analyze the latter relationship. In a two‐period optimal insurance contract in which the insured's risk profile is partly governed by her effort on prevention, we find that both the insured's risk aversion and prudence play a crucial role. If absolute prudence is greater than twice absolute risk aversion, moral hazard justifies setting a higher premium in the first period but also greater premium discrimination in the second period. This result provides insights on the trade‐offs between long‐term insurance and the incentives arising from risk classification, as well as between inter‐ and intragenerational insurance. 相似文献

ABSTRACTIn this paper, we unify two popular approaches for the definition of actuarial ruin with implementation delays, also known as Parisian ruin. Our new definition of ruin includes both deterministic delays and exponentially distributed delays: ruin is declared the first time an excursion in the red zone lasts longer than an implementation delay with a deterministic and a stochastic component. For this Parisian ruin with mixed delays, we identify the joint distribution of the time of ruin and the deficit at ruin, therefore providing generalizations of many results previously obtained, such as in Baurdoux et al. (2016) and Loeffen et al. (in press) for the case of an exponential delay and that of a deterministic delay, respectively. 相似文献

Disasters are extraordinary situations that require significant logistical deployment to transport equipment and humanitarian goods in order to help and provide relief to victims. An efficient response helps to reduce the social, economic and environmental impacts. In this paper, we define and formulate a practical transportation problem often encountered by crisis managers in emergency situations. Since optimal solutions to such a formulation may be achieved only for very small-size instances, we developed an efficient genetic algorithm to deal with realistic situations. This algorithm produces near optimal solutions in relatively short computation times and is fast enough to be used interactively in a decision-support system, providing high-quality transportation plans to emergency managers. 相似文献
