The concept of modularity has gained recently a growing attention in the management literature as a key to explain the contemporary trends of industrial dynamics. A stronger exploitation of external «networkbased» economies with respect to internal «bureaucracy-based» economies is one of the...

We analyze three sets of income data: the US Panel Study of Income Dynamics (PSID), the British Household Panel Survey (BHPS), and the German Socio-Economic Panel (GSOEP). It is shown that the empirical income distribution is consistent with a two-parameter lognormal function for the low-middle...

We investigate the shape of the Italian personal income distribution using microdata from the Survey on Household Income and Wealth, made publicly available by the Bank of Italy for the years 1977-2002. We find that the upper tail of the distribution is consistent with a Pareto power-law type...

In this paper we apply the wavelets methodology to the analysis of the industrial production index of the G-7 countries between 1961:1-2005:5. The analysis is performed using a multi-scaling approach which decomposes the variance of the industrial production index and the covariance between the...

Schumpeter asserted that there were two types of business cycle theories: one in which cycles reflected dampened economic behavior and another in which cycles reflect explosive economic behavior. Both of these theories allowed that cycles could be either monotonic or oscillating. In this working...

In this paper we use the BDS test developed by Brock-Dechert-Scheinkman (1987) to investigate whether ARMA Models for the US real GNP generate i.i.d. residuals. The second step,after reviewing some results from Brock-Sayer (1988) and Scheinkman-LeBaron (1989), SL, we will use a different kind of...
