The equilibrium real exchange rate is approximated by reestimating a cointegration equation where variable interest depends on Mexico's GDP, US Industrial Production Index, sum private consumption, government consumption exports Mexico, fixed investment. use these variables to approximate relative supply demand two ...

The understanding of decision-making systems has come together in recent years to form a unified theory of decision-making in the mammalian brain as arising from multiple, interacting systems (a planning system, a habit system, and a situation-recognition system). This unified decision-making system has multiple potential access points through which it can be driven to make maladaptive choices,...

Using previously identified firm characteristics, we find that most of the negative returns to uncertain firms in months following high-sentiment periods fall within the three-day window...

This leads to 11,628 unique correlations/covariances of which to keep track bet...
