Modelling infrastructure as an international public good in a two-country modelof trade where each country’s social planner behaves strategically, we showthat the equilibrium levels of infrastructure are sub-optimal from a globalperspective...

We present in this paper the asymptotic properties of two-stage quantile regressionestimators. These results permit valid inferences in structural models estimated using quantileregressions, in which the possible endogeneity of some explanatory variables is treated viaancilliary predictive...

It is known that Dickey-Fuller tests can lead to spurious rejections of the unit root nullhypothesis when the true generating process is difference-stationary with a break.Suppose now that an unsuccessful attempt is made to allow for a break, either throughmisplaced dummy variables or through...

A priori knowledge about the shape of living standards distribution has notbeen fully exploited in the literature to investigate properties of poverty indices.The method we propose is to exploit credible distributional assumptions to: generateadditional properties for poverty indices; relate the...

The hypothesis that futures price is an unbiased predictor of the future spot price has been oneof the most controversial topics in the empirical literature on market efficiency. The conflictingresults provided so far are not robust to the time period considered or to the econometricmethod...

Futures market efficiency has been one of the most researched topics for a number of years.The huge amount of results produced, highly dependent on the econometric techniquesadopted and on the time period analysed, are often conflicting: for a given market, someauthors find evidence of...

We derive an explicit formula of the Watts’ poverty index, in terms of parametersof bivariate lognormal distributions of price indices and nominal livingstandards. This result enables us to: analyse the contributions of the distributionsof prices and nominal living standards in poverty;...

The aim of this paper is to analyze the hypotheses of German dominanceand asymmetry in the European Monetary System (EMS).Weuse monthly data for British, Dutch, French, German, Italian, Spanishand US interest rates from January 1979 to the second half of 1997. Inparticular, we test the stability...

We generalize the stochastic revealed preference approach to consumers’ behavior introduced byBandyopadhyay, Dasgupta and Pattanaik (1999). We identify a restriction on stochastic demandbehavior that we term “Stochastic Substitutability” (SS)...

This note develops a method of recovering individual preferences, and of obtaining money-metricindividual welfare comparisons, from demand functions generated by Cournot-Nash equilibria ingames with public goods.
