Previous empirical studies analysing the effect of electoral systems on growth lack unanimous answers as they miss-specify mixed systems in the empirical setting, that is, they neglect to consider the proportionality degree of mixed electoral systems. This work supplies the missing answers by...

Economic and political literature widely studied the effects of electoral system on corruption. But very little attention has been dedicated to the role of political competition in explaining this relationship. We hypothesize that the proportionality degree of the electoral system impacts...

The amount of financial incentives required to stimulate network growth depends on the size of the <italic>critical mass</italic> which, in its turn, depends on the intensity with which network externalities play their role in the diffusion process. The measurement of the strength of network effects and all that...

I present a simple model of determination of the equilibrium size of a network with indirect network externalities. Indirect network externalities can generate complementarity between goods, and then the demand functions for the network good are those of the complementary goods: the result in...

This paper develops a simple demand model with network externalities which allow us to identify the shape of the network externalities function in the mobile telephone market and to estimate the critical mass. If the mobile telephone network exhibits positive network externalities, we expect...

This paper analyses how proportionality of the electoral system, political competition and corruption affect the total amount of Italian regional public consumption expenditure and alter the public budget structure. The Italian case is particular: from 1993 the country underwent a change in the...
