José De Sousa's personal website

I am a trade economist with special interests in behavioral economics.
The following questions provide an overview of topics I am interested in and currently conducting research on (check my google’s Work in Progress page!):
– Are exporters being too risk averse?
– Are consumer tastes affected by trade globalization?
– Is trustfulness a determinant of comparative advantage?
