ORBi Open Repository and Bibliography
In may 2007, the ULg's Administrative Board (joined in June 2007 by the FUSAGx) decided to create an institutional repository and defined a strong institutional self-archiving policy to increase the visibility, accessibility and impact of the University's publications (Board's decision).
This decision led to the official launch, in November 2008, of the ORBi platform including both the Academic Bibliography and the Institutional Repository of the Wallonia-Europe University Academy.

The double dividend of postponing retirement - Cremer, H.; Pestieau, Pierre
Early retirement seems to plague social security systems in a number of European countries. In this paper we argue that delaying retirement may have two positive effects: it is likely to partially restore the financial balance of the system, and it may foster redistribution among retirees. To obtain such a double dividend, the benefit rule of the initial social security scheme must have the following two characteristics. First, it operates redistribution within generations. Second, it is "biased" and induces early retirement.
Capital income taxation when inherited wealth is not observable - Cremer, H.; Pestieau, Pierre; Rochet, J. C.
This paper extends the Atkinson-Stiglitz model of direct and indirect taxation to a dynamic setting with two unobservable characteristics: productive ability and inherited wealth. Bequests are motivated by the 'joy of giving'. A child's inheritance is a random variable with a probability distribution that depends on his parent's investment in a 'bequest technology'. Public borrowing is assumed and implies the modified golden rule. We study the optimal tax policy when two instruments are available: a non-linear (wage) income tax and a proportional tax on capital income. We show that the second instrument ought, in general, to be used but that...
Voting on pensions with endogenous retirement age - Casamatta, G.; Cremer, H.; Pestieau, Pierre
It is often argued that the observed trend towards early retirement is due mainly to the implicit tax imposed on continued activity of elderly workers. We study the relevance of such a distortion in a political economy model with endogenous age of retirement. The setting is a two-period overlapping generations model. Individuals differ in their productivity. In the first period they work a fixed amount of time; in the second, they choose when to retire and then receive a flat rate pension benefit. Pensions are financed by a payroll tax on earnings in the first and in the second period...
Measuring poverty without the Mortality Paradox - Lefebvre, Mathieu; Pestieau, Pierre; Ponthiere, Grégory
Under income-differentiated mortality, poverty measures reflect not only the “true” poverty, but, also, the interferences or noise caused by the survival process at work. Such interferences lead to the Mortality Paradox: the worse the survival conditions of the poor are, the lower the measured poverty is. We examine several solutions to avoid that paradox. We identify conditions under which the extension, by means of a fictitious income, of lifetime income profiles of the prematurely dead neutralizes the noise due to differential mortality. Then, to account not only for the “missing” poor, but, also, for the “hidden” poverty (premature death), we...
