Current explanations of why a growing economy necessarily goes through booms and recessions predict a countercyclical R&D investment. As this is very controversial from an empirical perspective, a stochastic Poisson model of endogenous business cycles and growth is presented where the...

In this paper we develop analytic asymptotic methods to characterize time series properties of nonlinear dynamic stochastic models. We focus on a stochastic growth model which is representative of the models underlying much of modern macroeconomics. Taking limits as the stochastic shocks become...

We investigate the ability of workhorse structural change models in accounting for the business cycle properties of an economy. We consider three different preferences specifications: Herrendorf, Rogerson and Valentinyi (2014, HRV), Boppart (2014), and Comin, Lashkari and Mestieri (2021, CLM),...

We make three comparisons relevant for the business cycle accounting approach. We show that in theory, representing the investment wedge as a tax on investment is equivalent to representing this wedge as a tax on capital income as long as the probability distributions over this wedge in the two...

By revisiting the classic dirty-face problem we highlight the notion of 'unawareness' (a simpler state space) and compare it with 'impreciseness' (a coarser information partition). The outcomes are derived with various information structures. That allows us to 1) demonstrate a model of differing...
