We show that to account for the cross-sectional divergence in debt-to-income ratios in US data a DSGE model must assume a tax reallocation across the top- and bottom-income quantile of the population, rather than differential productivity growth, and low cost of access to financial intermediation. 相似文献

In this paper, we examine the effect of social norms on redistributive policies, where social norms are reflected in the degree of work participation among the different skill classes. Participation is driven both by the material incentives and heterogeneous preferences for leisure of each skill class, and by an endogenous social norm. Results for optimal redistributive taxation show that when the social norm enters as a benefit or cost for participants, participation taxes are generally lower than in its absence. Multiple participation equilibria can occur, and an engineered shift from a low‐ to a high‐participation equilibrium can be Pareto‐improving in the long run. 相似文献

We provide a computable algorithm to calculate uniform ε-optimal strategies in two-player zero-sum stochastic games. Our approach can be used to construct algorithms that calculate
uniform ε-equilibria and uniform correlated ε-equilibria in various classes of multi-player non-zero-sum stochastic games. 相似文献

Structural holes, innovation and the distribution of ideas 总被引:1,自引:0,他引:1
We model knowledge diffusion in a population of agents situated on a network, interacting only over direct ties. Some agents
are by nature traders, others are by nature “givers”: traders demand a quid pro quo for information transfer; givers do not.
We are interested in efficiency of diffusion and explore the interplay between the structure of the population (proportion
of traders), the network structure (clustering, path length and degree distribution), and the scarcity of knowledge. We find
that at the global level, trading (as opposed to giving) reduces efficiency. At the individual level, highly connected agents
do well when knowledge is scarce, agents in clustered neighbourhoods do well when it is abundant. The latter finding is connected
to the debate on structural holes and social capital. 相似文献

In this paper, we argue that credit market imperfections impact not only the level of unemployment, but also its persistence. For this purpose, we first develop a theoretical model based on the equilibrium matching framework of Mortensen and Pissarides (1999) and Pissarides (2000) where we introduce credit constraints. We show these credit constraints not only increase steady-state unemployment, but also slow down the transitional dynamics. We then provide an empirical illustration based on a country panel dataset of 20 OECD countries. Our results suggest that credit market imperfections significantly increase the persistence of unemployment. 相似文献

The aim of this article is to present a methodology for guiding enterprises to implement and improve interoperability. This methodology is based on three components: a framework of interoperability which structures specific solutions of interoperability and is composed of abstraction levels, views and approaches dimensions; a method to measure interoperability including interoperability before (maturity) and during (operational performances) a partnership; and a structured approach defining the steps of the methodology, from the expression of an enterprise’s needs to implementation of solutions. The relationship which consistently relates these components forms the methodology and enables developing interoperability in a step-by-step manner. Each component of the methodology and the way it operates is presented. The overall approach is illustrated in a case study example on the basis of a process between a given company and its dealers. Conclusions and future perspectives are given at the end of the article. 相似文献
