In a financial market with one riskless asset and n risky assets following geometric Brownian motions, we solve the problem of a pension fund maximizing the expected CRRA utility of its terminal wealth. By considering a stochastic death time for a subscriber, we solve a unique problem for bot...

This paper analyses the portfolio problem of an investor who wants to maximize the expected power utility of his terminal wealth both in a complete and an incomplete financial market. We derive sufficient conditions for having a closed form solution. These conditions must hold on a suitable...

In this paper, we take into account a very general setting with : (i) a set of stochastic investment opportunities, (ii) a set of risky assets, (iii) a riskless asset paying a stochastic interest rate, (iv) a stochastic inflation risk, (v) stochastic labor income , and (vi) HARA preferences. We...

In some countries the reform of public health care provision has been accompanied by a parallel process of devolution that has also entailed the organisation of health care becoming a regional competence. However, the application of fiscal federalism in the context of the provision of health...

This paper assesses whether short-lived jobs (lasting one quarter or less and involuntarily ending in unemployment) are stepping stones to long-lastinc jobs (enduring one year or more) for Belgian long-term unemployed school-leavers. We proceed in two steps. First, we estimate labour market...

We analyze the dynamic interaction between civil society organizations and Government in a representative developing economy. Government favors corruption and so fails to build efficient institutions. On its side, civil society exerts pressure on Government to constrain it to halt corruption. We...

The paper assesses the global effects of brain drain on developing economies and quantifies the relative sizes of various static and dynamic impacts. By constructing a unified generic framework characterized by overlapping generations dynamics and calibrated to real data, this study incorporates...

Recent theoretical studies suggest that migration prospects can raise the expected return to human capital and thus foster education investment at home or, in other words, induce a brain gain. In a recent paper (Beine, Docquier and Rapoport, Economic Journal, 2008) we used the Docquier and...

This paper studie the optimal income redistribution and monitoring when disability benefits are intended for disabled people but where some able agents with high distastes for work mimic them (type II errors). Labour supply responses are at the extensive margin and endogenous takeup costs burden...

The notion of frictional unemployment first arose in the writings of Beveridge, Pigou and Hicks. Why did it fail at the time to grow into a fully fledged theory ? Our answer is simple. This failure was due to the fact these economists were unwilling and/or unable to go beyond the then-prevailing...
