Considerable efforts have been made in the recent years to produce detailed topolo- gies of the Internet. While Internet topology data have brought to the attention of a wide and somehow diverse audience of scholars they have been so far over- looked by economic analyses. In this paper we...

It is commonly found that distributions that seem to be lognormal over a broad range change to a power-law (Pareto) distribution for the last few percentiles. The distributions of species abundance, income and wealth as well as file, city and firm sizes are examples with this structure. We...

This paper addresses the issue of a coordinated adjustment plan (“new Plaza") to close global imbalances. We show that the complexity of the network of bilateral trade imbalances has increased, revealing that any plan focusing on industrialised countries only is likely to be ineffective. By...

The paper analyzes the link between financial constraints and firms' export decisions, using a large micro-level data set on French Manufacturing firms over the 1996-2004 period. Our main finding is that firms enjoying better ex-ante financial heath are more likely to start exporting. This...

The paper analyses the relationship between trade, financial integration and business cycle synchronization in the euro area. The introduction of the euro has had a noticeable impact on European financial markets. Evidence that capital market integration exerts a positive effect on output...

L'articolo discute la possibile introduzione di una moneta palestinese. L'attuale situazione consiste in una doppia unione monetaria con Israele e Giordania che comporta una serie di effetti di tipo macro e microeconomico. La parte centrale del saggio contiene una stima econometrica della...

We question the claim that the largest US cities are Pareto distributed. We show that results of multiple tests on real data are similar to those obtained when the true distribution is lognormal, and largely depend on sample sizes.

In this paper we develop a network model of international trade which is able to replicate the concentrated and sparse nature of trade data. Our model extends the preferential attachment (PA) growth model to the case of multiple networks. Countries trade a variety of goods of different...

In this paper we develop a methodology to analyze and compare multiple global networks. We focus our analysis on the relation between human migration and trade. First, we identify the subset of products for which the presence of a community of migrants significantly increases trade intensity. To...
