When focusing on firm’s risk-aversion in industry equilibrium, the number of firms may be either larger or smaller when comparing market equilibrium with and without price uncertainty. In this paper, we introduce risk-averse firms under cost uncertainty in a model of spatial differentiation...

We consider a dual labor markets model in which the primary sector requires the presence of efficiency wage, while the secondary sector is competitive. We show that the Solow condition does not hold in a Stackelberg equilibrium where the primary sector acts as a leader and the secondary one as a...

In this paper, we extend the framework of the motives for familial solidarities to three generations. By focusing on upward transfers, we examine the demonstration effect hypothesis where individuals make transfers to their parents in order to be helped in return by their children. We show the...

In this note, we use the theory of incentive contracting to characterize the pattern of financial transfers within the family. Using an altruistic model based on bounded rationality with one parent and two children, we show that the parent may provide a lower gift to the less well-off child,...

We consider a model of international migration with heterogeneity in the skill level of workers which accounts for country−specific educational investment, unemployment expectations and return to the origin country. We prove that migrants invest less than natives in human capital formation...

This paper accounts for work sharing and unemployment in an efficiency wage model.The Solow condition holds when working hours are exogenous. Under the assumption of endogeneity and using general forms for the effort and cost functions, we prove that work sharing may have a reducing impact on...

Three theoretical hypotheses can explain the motives behind familial transfers given to the elders : altruism, exchange, and the demonstration effect theory where adults have to set an example by helping their elders if they want to be helped in turn by their children. This paper focuses on a...

This paper examines the altruistic model of bequest when a child inherits life standard aspirations from his parents. We prove that the impact of the aspiration effect on transfers can be positive or negative, depending on both the strength of inherited tastes and the coefficients of risk...

According to the demonstration effect theory, parents make intergenerational transfers to their elders in order to elicit a symmetric future behavior from their children. In this paper we show that upstream transfers are expected to increase with low returns from alternative financial assets and...

We develop a model of intergeneratioal coresidence and transfers within the family in a setting of asymmetric information. Following an exchange motive altruistic parents receive services from their children, who may make them financial gifts in return. However, parents do not know the privacyc...
