Maurice Potron is an important precursor of the study of linear models of production and, in particular, of input–output analysis. We show that, contrary to Abraham-Frois and Lendjel's interpretation which we consider as unfaithful to Potron's model, there is a clear connection between his theory and the Perron-Frobenius theorem. 相似文献

This paper investigates the causal impact of large unexpected windfalls on individual mental health, physical health, as well as health behaviors. I use a large individual-level panel data set of lottery winners from Germany between the years 2000 and 2011 and observe lottery winners before and after winning a large lottery prize. Mental health declines immediately after winning a large lottery prize for individuals with low education and low levels of financial literacy. While these individuals report being happier after winning the lottery, evidence from commonly used SF-12 measures of mental health indicates that winners with low education experience increased role limitations due to emotional problems, are more anxious, and have less energy after their win. The impact on various measures of mental health is highly robust, statistically significant, economically significant, and persists for up to two years after the win. Unexpected windfalls have no impact on the mental health of individuals with high education or high financial literacy. Winning the lottery has no impact on individuals’ health behaviors such as smoking or alcohol consumption, and it has no impact on doctor visits, hospital stays, or illness-related work absences regardless of education level. 相似文献

The paper analyzes the degree of output persistence in GDP in order toempirically discriminate between the Solow growth model, the perfect competition endogenous growth model and the imperfect competition endogenous growth model for the case of Austria. Wefind that a shock in the growth rate of output induces a permanent and larger effect on the level of GDP. This leads us to refute the Solow growth model and the perfect competition model of endogenous growth.We may not reject the imperfect competition growth model. 相似文献

In this paper, we provide two basic properties of utility functions u which exhibit decreasing absolute prudence i.e. (− u/u″)′ ≤ 0. These properties are used to examine the allocation of risks in an economy when some agents bear non-transferable risks. We show that it is fair Pareto-efficient to let those with a non-transferable risk bear relatively less of the transferable risk in the economy if and only if absolute prudence is decreasing. In another model, there is a complete set of contingent markets, but some agents have no direct access to them. We examine the fair efficient allocation of risk in a pool gathering a trader and a non-trader. Decreasing absolute prudence provides an upper bound to the share of the pool's risk that should be borne by the trader. 相似文献

This article studies the role of risk sharing in dynamic credit relationships that are secured by physical collateral. It is shown that, when borrowers and lenders cannot commit not to terminate relationships (through default in the first case and liquidation in the second), overinvestment is optimal. Overinvestment facilitates risk sharing in this context: It occurs in expectation of periods in which lenders are unwilling to supply all the funds necessary to achieve complete risk sharing. Typically, overinvestment happens when investment decreases; it slows down the pace at which the capital stock is reduced and therefore results in production smoothing. 相似文献

We consider a one-sector growth model in continuous time with a production externality and endogenous labor supply. There is a continuum of households who have identical preferences but differ with respect to their initial wealth. We show that there exist economies such that an indeterminate steady state exists for some wealth distribution but not for others. A second result is that a redistribution of wealth may drive the economy from a steady state with strictly positive output to a poverty trap in which output converges asymptotically to zero. These results indicate that differences in the wealth distribution may be responsible for drastic differences in the long-run standard of living.

As business-to-business marketing channels become more international in scope, communication in channels occurs among a more diverse set of channel participants from different national cultures. Do such cultural variations influence channel communications and if so, how? This study examines these questions in international business-to-business marketing channels comprised of channel members representing different cultural contexts. The findings show that there is a relationship between culture and channel communication in international channels. This influence stemming from “cultural distance” may have significant implications as business moves into the E-commerce era of Internet-based B2B international channels of distribution. 相似文献
