A quadratic discrete time probabilistic model, for optimal portfolio selection in (re-)insurance is studied. For positive values of underwriting levels, the expected value of the accumulated result is optimized, under constraints on its variance and on annual ROE's. Existence of a unique...

We propose a novel portfolio selection approach that manages to ease some of the problems that characterise standard expected utility maximisation. The optimal portfolio is no longer defined as the extremum of a suitably chosen utility function: the latter, instead, is reinterpreted as the...

This paper considers a two-country world where the population in one country grows faster than the other, and investigates the implications of the addition of non-stationary population dynamics to a simple 2- commodity, 2-factor model of international trade within an overlapping- generations...

This paper presents the methodology and results of labour force projections over the long term (until 2050) for each of the 25 EU Member States. These projections were undertaken in order to provide the background technical inputs for the assessment of the potential economic and fiscal impact of...

This paper looks at the evolution of the labour markets in Estonia, Latvia, and Lithuania since the beginning of transition (in some respects since 1996/1998) until 2003, with a particular focus on labour force participation. How did labour supply in the Baltic countries respond to changes in...

Seit zwei Jahrzehnten wird in Deutschland wie in Frankreich eine Sozialpolitik betrieben, die größtenteils auf einer gemeinsamen Einschätzung der Probleme und Herausforderungen beruht, die sich aus der zunehmenden Alterung der Gesellschaft und dem Druck zu mehr Wettbewerbsfähigkeit und...

When it comes to retirement income policy, there is a general perception that workers have full 40-year working careers before retiring. Further, it is generally assumed that workers with low lifetime earnings have low earnings in each year during a normal working career. The basic research...

What is the optimum quantity of money in a society? This paper answers this question both from the perspective of a utility maximizing model with real balances in the utility function, and employing an inventory theoretic model which focuses attention on the costs of transacting in different...

This paper decomposes the overall market beta of common stocks into four parts reflecting uncertainty related to the long-run dynamics of stock- specific and market-wide cash flows and discount rates. We employ a discrete time version of Merton�s Intertemporal CAPM to test whether these four...
