The design of a probability sample jointly determines the method used to select sampling units from the population and the estimator of the population parameter. If the sampling fraction is constant for all the units in the sample, then the unweighted sampling mean is an unbiased estimator. In...

This paper compares the evolution of trade specialisation, by technological content, of Emilia-Romagna, Lombardia, Marche, Veneto and the Italian average over 1992-2002. It is shown that, over the period, the four regions� export performance has been negatively affected by the stationarity...

The paper provides an analysis of the problems of construction of quality-adjusted price indexes within the framework of the theory of product differentiation. In the general case of price-making behaviour on the part of firms, hedonic regressions are defined on the basis of reduced forms of the...

Recent contributions have suggested that technology shocks have a negative short-run effect on labor input, contrary to the predictions of standard flexible-price models of the business cycle. Some authors have interpreted this finding as evidence in favor of stickyprice models, while others...

Quantitative information on the current state of the economy is crucial to economic policy-making, but the quarterly national accounts data for GDP in the euro area are released with a significant delay. This paper presents alternative models for the real-time forecasting of euro area GDP and...

We study the relation between workers� skill dispersion and firm productivity using a unique dataset of Italian manufacturing firms from the early eighties to the late nineties with individual records on all their workers. Our measure of skill is the individual worker�s effect obtained...

This paper estimates a pricing-to-market equation for Italy over the period 1990-99 with the aim of assessing the degree of exchange rate pass-through (ERPT). As compared to previous works, we minimize aggregation and selection biases using export data on all products (about 700 from 4 digits of...

We use input-output tables to estimate the import content (IC) of exports for several European countries, interpreting this as a measure of internationalisation. Between 1995 and 2000 the IC grew everywhere but in France; the transport equipment sector emerged as the most internationalised one....

I show how cyclical aggregate shocks can stimulate structural reallocation activities, which in turn amplify the effect of the shock. I emphasize the informational aspects related to restructuring activities and their potential interplay with aggregate shocks. Building on work by Caplin and...

We present the “fixed exchange rate” version of the Obstfeld and Rogoff model and analyze the international transmission of fiscal policy shocks. It is shown that the welfare effects of an unanticipated contraction in government expenditure in the home country crucially depend on the way in...
