Microeconomic data often have within-cluster dependence. This dependence affects standard error estimation and inference in regression models, including the instrumental variables model. Standard corrections assume that the number of clusters is large, but when this is not the case, Wald and...

We investigate the empirical evidence on the Euler equation models using methods that are robust to weak instruments and structural changes for a set of eight countries. We start with the conventional closed economy model and consider extensions that include habits and hand-to-mouth consumers....

We study the effects of financial uncertainty on investment dynamics in the U.S. using a vector autoregression with drifting parameters and stochastic volatilities. We find time-varying negative effects of financial uncertainty shocks on investment. These effects have declined in the post-WWII...
