We study the economics and finance scholars’ reaction to the 2008 financial crisis using machine learning language analyses methods of Latent Dirichlet Allocation and dynamic topic modelling algorithms, to analyze the texts of 14,270 NBER working papers covering the 1999–2016 period. We find...

I characterize optimal government policy in a sticky-price economy with different types of consumers and endogenous financial constraints in the banking and entrepreneurial sectors. The competitive equilibrium allocation is constrained inefficient due to a pecuniary externality implicit in the...

This paper investigates theoretically how financial development affects the magnitude of financial amplification. Financial development yields two competing effects, balance sheet effects and shock cushioning effects. Depending on which of these forces dominates, we find that financial...

We construct an open-economy DSGE model with a banking sector to analyse the impact of the recent credit crunch on a small open economy. In our model the banking sector operates under monopolistic competition, collects deposits and grants collateralized loans. Collateral effects amplify monetary...

A recent study shows that equilibrium indeterminacy arises if monetary policy responds to asset prices, especially share prices, in a sticky-price economy. We show that equilibrium indeterminacy never arises if the working capital of firms is subject to their asset values by financial frictions.

This paper analyzes housing market boom-bust cycles driven by changes in households' expectations. We explore the role of expectations not only on productivity but on several other shocks originated in the housing market, the credit market, the production sector and the conduct of monetary...
