This paper reviews the recent literature on game-theoretic models of market structure and their empirical implementation.

The demographic database of Istat (www.istat.it)is explored and the main facts are extracted and described, both at the aggregate national level as well as at the regional one. This paper is completely self-standing but, at the same time, poses the basis for a more general analysis that will be...

This paper proposes an equilibrium concept for a class of games in which players make irreversible costly decisions; these games have been widely used in the recent I.O. literature. The equilibrium concept is defined, not in the space of strategies, but in the space of (observable) outcomes. It...

This paper introduces a novel analysis of the classic “persistence of leadership” question, and applies it to a newly constructed dataset for Japanese manufacturing. The analysis rests on an appeal to an empirical “scaling relationship” between current market share and the variance of...

This paper traces the time series (?Growth of Firms?) tradition in the study of market structure and looks at how recent studies on entry and the size distribution of firms have modified thinking in this area.

The Ecofin-Oecd methodology is applied to reconstruct the health care expenditure evolution in Italy and in the Region Emilia Romagna. The reconstructed series can be compared to the historical series, highlighting the different capabilities of the Italian average and of the Region Emilia...

Data from Stability Programs (European Countries) and from Us Congress Budget Office and Us Bureau of Census are collected to investigate the burden each worker will have to bear in the future in order to finance pension and health care provisions. If the private side of the system is based,...

The demographic database of Eurostat and of Us Census of Bureau are explored and the main facts are extracted and described. This paper is completely self-standing but is also part of a more general analysis dedicated to the functioning and sustainability of pay-as-you-go to finance the welfare...

We use the same methodology, that Ecofin-Oecd apply for projecting expenditure in the medium-long term, to reconstruct expenditure in the medium-long past. It is possible to compare the effective expenditure with the reconstructed one. The effective expenditure is of course influenced by policy...
