In this paper, we present a new methodology based on vine copulas to estimate multivariate distributions in high dimensions, taking advantage of the diversity of vine copulas. Considering the huge number of vine copulas in dimension n, we introduce an efficient selection algorithm to build and...

The ultimate goal of risk management is the generation of efficient incomes. The objective is to generate the maximum return for a unit of risk taken or to minimise the risk taken to generate the return expected i.e. it is the optimisation of a financial institution strategy. Therefore, by...

Conditional dependence is expressed as a projection map in the trivariate copula space. The projected copula, its sample counterpart and the related process are defined. The weak convergence of the projected copula process to a tight centered Gaussian Process is obtained under weak assumptions...

We present a new recursive algorithm to construct vine copulas based on an underlying tree structure. This new structure is interesting to compute multivariate distributions for dependent random variables. We proove the asymptotic normality of the vine copula parameter estimator and show that...

This paper introduces two new commands, smpred and smmatch, that implement the statistical matching procedure proposed by Rubin (1986). The purpose of statistical matching in Rubin's procedure is to generate a single dataset from various datasets, where each dataset contains a specific variable...

Using a very detailed set of French firms' data on trade flows and balance sheets, this paper analyses to what extent firms' financial frictions, considered as the interaction of financial dependence and financial constraints, and trading time affect their trade flows. In this empirical study...

It is argued that compared with large countries, small countries rely more on trade and therefore they are more likely to adopt liberal trading policies. The present paper extends this idea beyond the conventional trade openness measures by analyzing the relationship between country size and the...

There is ample evidence that a country's labour market institutions are important determinants of unemployment. This study generalises Davis' (1998) idea according to which the institutions of the trade partners matter also for a country's equilibrium unemployment rate as they generate...

This paper estimates an augmented gravity model incorporating different aspects of Trade Facilitation in develop and developing countries. Trade Facilitation is defined as measures that aim at making international trade easier by eliminating administrative delays, simplifying commercial...

Exploiting data on product-destination level transactions of a large panel of Italian firms, we provide new evidence on the effect of financial constraints on price variation across exporters. Controlling for firm characteristics and endogeneity, constrained exporters charge higher prices than...
