The HMR model extends the classical gravity model of trade to correct for the large number of zeros in the world trade matrix (export selection) and for the unobservable fraction of exporting fi�rms (extensive margin). They �find that, while omission of both of these corrections result in...

The aim of the present work is to test empirically the feasibility of the broad expectations regarding the effects of ENP on the EU-MED economic partnership. More specifically, it presents firstly a gravity analysis of the patterns of trade in the EU-MED area to test the actual dimension of...

The share of North-North trade in global trade declined from 55.5 percent in 1990 to around 32 percent in 2010. Such fall in North-North trade had been accompanied by rising trade involving the South countries. The South-North trade share increased from 13.9 percent to 16.5 percent during the...

The aim of the paper is to propose a new simple frictionless model of international trade shares as an alternative to standard gravity models. In the proposed model (total) shares of export from a given country depend only on a gross domestic product and a distance of importing countries. The...

This paper assesses, using a panel data model, the determinants of Morocco’s exports. Estimates are conducted for 9 different categories of products. The model takes into account observed and non-observed individual heterogeneity. The results show that for most of the groups of exported...

This paper provides an empirical evidence of the impact of foreign trade on the sectorial productivity for the Tunisian manufacturer sector. The objective is to show that the insufficiency of the traditional theory in the explanation of the impact of the international trade on the labour market...

In recent years empirical studies offer clear evidence on the increasing importance of intra-industry trade in presence of vertically differentiated products. These are goods that, within the same industry, are distinguished by different quality levels. In the new trade theory and in the...

We develop a model of international trade with two sources of firm heterogeneity: "productivity" and "caliber". Productivity is modeled as is standard in the literature. Caliber is the ability to produce quality using few fixed inputs. While there is no quality restriction to sell domestically,...

This paper examines inter-country variations and growing volume of Intra-industry trade for thirty rapidly industrializing Asian and Latin American countries in the 1990s. With rapid industrialisation, intra-industry trade in manufactured products have increased substantially. We find that...

The link between regional integration and intra-industry trade (IIT) has been under scrutiny since it has been first suggested by the European integration process. However, the lack of reliable data and the difficulty to find a robust model for IIT made this relationship difficult to prove. This...
