The objective of this paper is to analyze the concept and determinants of "sovereign risk" and the role of the credit risk rating agencies which serve internationally as the main reference instruments employed by economic agents to assess this risk. The paper also tries to identify macroeconomic...

This paper assesses the impacts of the Mercosul Preferential Trade Agreement on Brazil's regions and their industries between 1990 and 2000 by means of a gravity model, extended to include dummy variables for Mercosul, for a Brazilian region and for a industry within a region. The results show...

In this paper we assess the impacts of the Mercosul preferential trade agreement on Brazil's regional trade flows by means of a gravity model, extended to include dummy variables for Mercosul and for a Brazilian region. Using panel data, we implement the model in three different ways: a pooled...

This paper analyzes the impacts of selected trade facilitation measures on international trade flows. A gravity model is used to estimate four equations: a pooled cross-section model; a fixed-effects model; a random effects model; and a Poisson maximum likelihood estimator. The contribution of...
