Preferences of a Decision Maker define a valuation function on future uncertain payoffs. Consistency of this unconditional valuation function with valuation conditional on information arrivals is justified by a no Money Pump argument. A result on the updating of capacities is obtained in a...

This paper introduces a new long memory volatility process, denoted by Adaptive FIGARCH, or A-FIGARCH, which is designed to account for both long memory and structural change in the conditional variance process. Structural change is modeled by allowing the intercept to follow a slowly varying...

According to traditional IO models, the characteristics of market demand (intercept, slope, elasticity) and of technology (level of symmetric marginal costs) do not play any role in defining the sustainability of collusive behaviors in Bertrand oligopolies. The paper modifies this...

Venture capitalism is an outcome of the ICT Revolution, which made its appearance first in the US during the late 1970s and early 1980s and then in other countries including Israel during the 1990s. It explains the new pervasive role of small firms in the introduction of technological...

In this paper the contributions of economic and financial integration to international stock markets comovements are investigated by means of a large scale macroeconometric model, set in the factor vector autoregressive framework (FVAR). The findings point to a key role of both economic and...

The purpose of this paper is to present an exercise where we identify optimal income tax rules under the constraint of fixed tax revenue. To this end, we estimate a microeconomic model with 78 parameters that capture heterogeneity in consumption-leisure preferences for singles and couples as...

This paper analyses exchange rate control measures adopted in Italy and Bulgaria during the interwar period. The first two sections provide a detailed account of the institutional and economic framework in which these measures were enforced and interpret them utilizing statistical data. In the...

In the paper a new approach to the modelling of common components in long memory processes is introduced. The approach is based on a two-step procedure relying on Fourier transform methods (firrst step) and principal components analysis (second step), which, differently from previous...

In this paper international comovements among a set of key real and nominal macroeconomic variables for the G-7 countries have been investigated for the 1980-2005 period, using a Factor Vector Autoregressive approach. We present evidence that comovements in macroeconomic variables do not concern...

In this paper, a theoretical model was constructed to endogenously determine environmental weights in the agricultural sector. The conventional Political Preference Function was extended to include environmental weights. The model was applied to the wheat sector in the EU for the years 1990 and...
