This paper deals with a constrained investment problem for a defined contribution (DC) pension fund where retirees are allowed to defer the purchase of the annuity at some future time after retirement. This problem has already been treated in the unconstrained case in a number of papers. The aim...

We consider the portfolio selection problem in the accumulation phase of a defined contribution (DC) pension scheme. We solve the mean-variance portfolio selection problem using the embedding technique pioneered by Zhou and Li (2000) and show that it is equivalent to a target-based optimization...

The financial crisis of 2007-08 has underscored the importance of adverse selection in financial markets. This friction has been mostly neglected by macroeconomic models of financial frictions, however, which have focused almost exclusively on the effects of limited pledgeability. In this paper,...

This article uses survey data of 90,000 union employees working in 62 publicly-traded companies in Japan between 1990 and 2004 to study the effect of both own and self-reported reference wages on workers' subjective well-being levels. The availability of self-reported reference wages generates...

Previous researchers have modelled the decision to accept a donor organ for transplantation as a Markov decision problem, the solution to which is often a control-limit optimal policy: accept any organ whose match quality exceeds some health-dependent threshold; otherwise, wait for another. When...

Despite the fact that the distributional impact of innovation has been recognized in the social science literature, hardly any work has been done on the distributional politics of innovation policy. This study offers a first step in this direction as well as asking whether a government’s...

Negli archivi amministrativi dell’INPS, e in particolare nei dati dell’Osservatorio delle Imprese, il settore di attività economica è identificato in base a diverse classificazioni. I dati più recenti riportano la codifica Ateco 2002, validata dall’ISTAT nell’ambito del progetto ASIA...

L'aggancio tra i dati WHIP e quelli del Casellario degli Attivi consente l'osservazione di tutti i percorsi lavorativi, non solo quelli coperti dai dati INPS (o WHIP). Questa procedura ha permesso di dare una parziale risposta ad una domanda che ci si pone quando si usano i dati WHIP, o di fonte...
