The Behavioral Portfolio Theory (BTP) developed by Shefrin and Statman (2000) considers a probability weighting function rather than the real probability distribution used in Markowitz’s Portfolio Theory (1952). The optimal portfolio of a BTP investor, which consists in a combination of bonds...

A new definition of service has been proposed by Hill (1999) and endorsed by SNA and BOP last updates. The paper studies its consequences for industrial classifications, such as ISIC, and on the respective shares of goods and services producing sectors. The first section reminds the main...

Using a two-country DSGE model, we analyze the spillover effects of fiscal policy in a monetary union. Based on a non-Walrasian labor market and a detailed fiscal sector, our analysis focuses on the relative cross-border effects of different kinds of fiscal instruments (expenditure side and...
