1. Introduction In this post, I solve a simple noisy rational expectations equilibrium model from Grossman and Stiglitz (1980) and then give a geometric interpretation of their result. First, in Section 2 I set up and solve a noisy rational … [Continue reading]
In this note, I show how to set up a local Mongo DB database to house CRSP-COMPUSTAT data. I grew tired of having to use SAS to access these data on the WRDS server. The coding language is difficult to use and the server is not particularly … [Continue reading]
