We provide a systematic decomposition of world trade using harmonized bilateral flows at the most available detail (some 5,000 product categories), into three trade types: inter-industry, intra-industry in horizontally and in vertically differentiated products. The analysis is diachronic and...

There are several possible explanations for the observed changes in inequality, the returns to education, and the gap between the wages of informal and formal salaried workers in Argentina over the period 1980-2002. Largely due to the lack of evidence for competing explanations, skill-biased...

We show in the paper that the decomposition proposed by Beveridge and Nelson (1981) for models that are integrated of order one can be generalized to seasonal Arima models by means of a partial fraction decomposition. Two equivalent algorithms are proposed to optimally (in the mean squared...

Motivated by the Kyle-Back model of “insider trading”, we consider certain classes of linear transformations of two independent Brownian motions and study their canonical decomposition as semimartingales in their own filtration. In particular we characterize those transformations which...

Dynamic multistage stochastic linear programming has many practical applications for problems whose current decisions have to be made under future uncertainty. There are a variety of methods for solving these problems, including nested Benders decomposition. In this method, recently shown to be...

This paper applies a new methodology to decompose the overall redistributive effect (RE) of health care finance on income distribution. Contrary to most previous studies, the RE of various financing schemes are disentangled and estimated as sample statistics to reveal the vertical and horizontal...

Over a five-year period in the 1990s Vietnam experienced annual economic growth of more than 8% and a decrease of 15 points in the proportion of children chronically malnourished (stunted). We estimate the extent to which changes in the distribution of child nutritional status can be explained...
