Using quarterly data of 58 countries, this paper provides empirical evidence that mobile phone diffusion from 2007 to 2009 is positively influenced by international network effects. Direct and indirect network effects are a result of the international standadization of telecommunication...

This paper presents a simple two country model in which firms in manufacturing sector choose a technology level (high or low). I show how trade integration and productivity differential affect technology choice clearly. In particular, if the gap of productivity of high technology is medium,...

Nonlinear estimation of the gravity model with Poisson/negative binomial methods has become popular to model international trade flows, as it permits a better accounting for large numbers of zero flows. Nevertheless, as trade flows are not independent of each other due to spatial...

The present paper studies the modelling of inter-regional trade flows in the newly developed general equilibrium model of European Commission, Rhomolo. In contrast to international trade, usually, trade of goods and services between regions is not recorded statistically. As a result, no...

We use firm-level data for 15 countries and 13 manufacturing sectors to estimate firm-level productivity parameters and to establish representative country-sector-specific empirical productivity distributions. We use these distributions against the backdrop of multi-sector versions of the models...

In previous research, we analysed the effect of technological innovation, understood as absorptive capacity, on exports by using a gravity model of trade for the year 2000 (see Márquez-Ramos and Martínez-Zarzoso, 2009). We found that the effect of technological innovation on trade varies...

We evaluate whether survey-based indicators produce lower forecast errors for export growth than indicators obtained … with country-specific export compositions. A larger share in raw material or oil exports worsens the accuracy of soft … indicators, we find only weak evidence for the export composition to explain differences in forecast accuracy. …
