August 1999 - The results of a modified gravity model suggest that the new wave of regionalism has not boosted intra-bloc trading significantly. Trade liberalization in Latin America did have a positive impact on the imports of bloc members, although MERCOSUR's exports did poorly over the...

One problem when estimating a Cobb-Douglas production function with micro data is how to deal with the observations that show positive output but do not use some of the inputs. As the log of zero is not defined one standard procedure is to arbitrarily replace those zero values with "sufficinetly...

This paper discusses the measurement of ex-ante inequality of opportunity for binary outcome variables. We argue that the use of scale but not translation invariant inequality measures such as the dissimilarity index might be problematic depending on the aim of the study. The main concern is...
