International trade can increase both beneficial and harmful choices available to consumers and to firms. The debate about appropriate technology warned us to pay attention to pre-consumption choices. Later work on sustainable development alerted us to be aqually prudent about post-coosumption...

This paper develops an e±cient method for estimating the discrete mix- tures of normal family based on the continuous empirical characteristic function (CECF). An iterated estimation procedure based on the closed form objective distance function is proposed to improve the estimation effciency....

This paper presents a two-country, two-good, two-currency overlapping generatioons models that features limited participation and costly state verification inthe credit market.

This paper extends the stochastic conditional duration model by imposing mixtures of bivariate normal distributions on the innovations of the observation and latent equations of the duration process. This extension allows the model not only to capture the asymmetric behavior of the expected...
