We study the stability properties of a Diamond (1965) overlapping generations model in which agents have to pay transaction costs related to the capital accumulated. In particular, these costs depend positively on the amount of individual's savings. At first, we show that under stan- dard...

We consider a Ramsey model with heterogeneous agents and borrow- ing constraint. Heterogeneity across agents stems from di¤erent initial capital endowment, labor supply, felicity function and discount rate. For simplicity, heterogeneity is reduced to only two groups of agents where they are...

In this paper, we present a dynamic general equilibrium model with two sectors: one aggregate firm produces consumption good and a second one investment good. We assume sector specific as well as aggregate ex- ternalities. Moreover, we account for variable capital utilization i.e. the...

This paper aims to study the stability properties of a two-period over- lapping generations model (OLG) with a progressive labor-income taxa- tion rule. In this case, wage income tax rates are increasing with agent's income. Each representative agent lives two periods: youth and adult- hood. In...

The paper proposes a new application of the collective model of household be- haviour to the analysis of intra-household inequality using the answers to the ques- tions on subjective welfare. The collective approach attributes to each household member distinct preferences and assumes that...

We propose to study the trade off between two incentive strategies (moni- toring and efficiency wage versus profit sharing), operated by one firm to induce more efforts among employees. We deal first with a normal context where shirkers bear the risk to be fired. We consider second a particular...

We study the optimal dynamics of an AK economy where population is uniformly distributed along the unit circle. Locations only differ in initial capital endowments. Spatio-temporal capital dynamics are described by a parabolic partial differential equation. The application of the maxi- mum...
