Several studies have attributed the rise of household bankruptcy in the past two decades to the decline of social stigma associated with default. Stigma explanations, however, cannot account for the large increase in the use of unsecured credit during this period. I explain the simultaneous increase in bankruptcy rates and unsecured credit as the result of improvements in credit-rating technologies. Using an environment where borrowers face heterogeneous default costs (unobservable by creditors), I show that such improvements will lead to agents with high default costs, i.e., “safe” borrowers, being able to borrow more. A quantitative example illustrates that this increased access to credit can be large enough to raise both equilibrium borrowing and default rates.  相似文献

This paper analyses the efficacy of regional and federal government policies in reducing inter‐regional unemployment disparities. We use as our framework a two‐region general equilibrium model with a given freely‐mobile supply of labour. We assume inter‐regional migration to occur in response to inter‐regional utility differentials. Each region has households, firms and a regional government. In addition to regional governments, there is a federal government. The firms in a region use a single factor, labour, to produce a single good which we assume to be different to that produced in the other region. It is supplied to households and to the regional government in the form of payroll taxes. Households consume some, trade some with households in the other region and give some up to the federal government as income tax. Firms and households bargain over wages and firms then choose employment to maximise profits. The resulting equilibrium will generally not be a full‐employment one. We simulate a linearised numerical version of the model. We examine seven alternative policies, six carried out by a regional government and one by the federal government. In the first group there are traditional tax/expenditure polices as well as policies which might be seen as attacking the natural rate of unemployment: changes in unemployment benefits, changes in union power, changes in the labour force and changes in labour productivity. The federal government policy is a regionally‐differentiated fiscal policy. Contrary to expectations, many policies which have traditionally been recommended to alleviate unemployment are found, in fact, to exacerbate the unemployment problem.  相似文献

Growth in overall life expectancy is straining the Social Security budget, and the gap in life expectancy between the rich and poor is widening. Motivated by these facts, this paper does four things. First, we develop a simple way to summarize the degree of progressivity in a Social Security system. Second, we show that growth in the life expectancy gap over the last few decades unwinds three-quarters of the progressivity of the Social Security system. Third, we develop simple reforms to Social Security that maintain the progressivity of the system and restore fiscal solvency. Fourth, we estimate the welfare effects of these potential reforms.  相似文献

We examine the innovation performance of MNE subsidiaries and their embeddedness in sources of local knowledge in a policy framework within the context of an emerging economy. Based on first-hand evidence from multiple case studies, we found that: (1) there was variability between the subsidiaries in terms of the cumulative manner and speed at which they improved their innovation performance over time, using progressively levels of accumulated capability as a proxy; (2) these differences in innovation performance improvement reflected heterogeneity between the subsidiaries in terms of the learning efforts made to acquire knowledge from local organizations; (3) the varied frequency in which the subsidiaries developed such local relationships reflects their differing responses to a common industrial policy that makes use of tax incentives to stimulate such links. The paper reveals the limitations of this conventional type of industrial policy in stimulating industrial development and the embeddedness of MNEs. It also suggests that a new direction for policy, which incorporates public–private negotiations and a focus on the firm-centred building of innovation capabilities, should be pursued in order to accelerate the innovation performance progress of latecomer firms.  相似文献

Selection and execution of site decontamination projects is often best left to local authorities, in accordance with the subsidiarity principle, even though the budget for such projects is made available through a central authority. In this paper we suggest a practical budget allocation policy which a central authority can employ to allocate budgets to local authorities, while still optimising the central authority's environmental objective function. The procedure is fully consistent with the principle of decentralisation of responsibility for selection and execution of projects, and requires a minimum information exchange between local and central levels. Despite the information asymmetry between local and central levels, incentive compatibility problems can be (partially) prevented by choosing an appropriate evaluation mechanism. At the same time, the procedure is computationally effective and efficient, and can guarantee a fair budget allocation, making it easy to implement and politically acceptable.  相似文献

Modeling the incidence of self‐employment has traditionally proved problematic. Although the supply‐side characteristics of the self‐employed are well documented, we argue that the literature has neglected demand‐side aspects. We explore the determinants of self‐employment using the U.S. Survey of Consumer Finances. We present results from an econometric framework that allows us to model, separately and simultaneously, the influences of individual heterogeneity (i.e., supply‐side factors) and employment type heterogeneity (i.e., demand‐side factors) on the probability of self‐employment. Our findings suggest that while individual characteristics are important determinants of self‐employment, there are factors specific to the type of employment that influence self‐employment.

Many new and proposed emissions trading systems involve multiple countries and regions. The introduction of interregional trading raises questions about how flexible state- or national-level authorities should be in allowing individual firms to trade with firms or authorities in other states or countries. This paper uses laboratory methods to evaluate the efficiency and pricing performance of linking trading across regions at the firm-to-firm level. In one treatment, individual firms trade directly with firms or authorities in other regions. We compare performance in this treatment to an intergovernmental trading treatment, where emissions trading is restricted to occur only between intermediaries. A baseline treatment of autarky, where firms only trade with other firms in their country or region, provides a benchmark to assess the efficiency benefits of allowing linking. Although efficiency and price discovery are both improved by allowing intermediation in linked permit markets, we find that further gains can be realized through direct firm to firm trading. Buyers in high cost regions and sellers in low cost regions benefit the greatest from linking.  相似文献

This paper analyses governance structures used to organize partnerships in R&D networks using two approaches: transaction costs theory and social capital theory. We argue that these theories are complementary; this explains forms of governance through the degrees of administrative (structural and safeguard mechanism) and social factors (cohesion and openness) they embody. Data was obtained from European R&D networks created through Framework Programmes which include a great number of universities, non profit institutions and firms. Findings show the variables that characterize and explain the governance forms based on the applicability of R&D networks. This study not only provides a theoretical model for analysing governance structures of these networks, but is also useful for both improving the management of networks and for fostering collaboration at an international level.  相似文献
