The Quarterly Journal of Economics, 2014 Abstract We develop a theory of endogenous uncertainty and business cycles in which short-lived shocks can generate long-lasting recessions. In the model, higher uncertainty about fundamentals discourages investment. Since agents learn from the actions of others, information flows slowly in times of low activity and uncertainty remains ...

A Class of Two-Person Zero-Sum Matrix Games with Rough Payoffs
International Journal of Mathematics and Mathematical Sciences, 2010 We concentrate on discussing a class of two-person zero-sum games with rough payoffs. Based on the expected value operator and the trust measure of rough variables, the expected equilibrium strategy and r-trust maximin equilibrium strategy are defined ...
