We show that the `fear' of globalisation can be rationalised by economic theory in the standard AD/AS equilibrium model, if we substitute the coordinational role of the Auctioneer by an implementation device based on learning (Guesnerie, 1992). When endowing producers with a learning ability to...

Exploiting French survey data, we empirically ascertain whether earnings uncertainty and borrowing constraints decrease households demand for risky assets, consistent with theoretical predictions. A major empirical problem is the potential endogeneity bias of income risk, as more risk averse...

How do exporters expand their product scope and geographical presence? We argue that new exporters are uncertain about their profitability in different countries and products, but learn it as they start to export. As a consequence, exporters add products and countries sequentially, in an...

This paper provides a survey of results concerning eductive stability of equilibrium in an abstract 2-period exchange economy. Eductive stability is based on the Common Knowledge considerations underlying the work reported in the book Assessing rational expectations: eductive stabiltiy in...

In this paper, we extend the static portfolio choice problem with a small background risk to the case of small partially correlated background risks. We show that respecting the theories under which risk substitution appears, except for the independence of background risk, it is perfectly...
