The aim of this paper is to establish the link between the high frequency dynamics of spot exchange rates and developments in the macroeconomy. To do so, I first present a theoretical model of exchange-rate determination that bridges the gap between existing microstructure and traditional...

This work presents closed-form solutions to Lucas's (2000) general equilibrium expression for the welfare costs of inflation, as well as to the difference between the general-equilibrium measure and Bailey's (1956) partial-equilibrium measure. In Lucas's original work only numerical solutions...

In the long run, we are all dead. Nonetheless, when studying the short-run dynamics of economic models, it is crucial to consider boundary conditions that govern long-run, forward-looking behavior, such as transversality conditions. We demonstrate that machine learning (ML) can automatically...
