This paper studies how the interplay between technological shocks and financial variables shapes the properties of macroeconomic dynamics. Most of the existing literature has based the analysis of aggregate macroeconomic regularities on the representative agent hypothesis (RAH). However, recent...

This paper develops a new international trade model with capital market imperfections and endogenous borrowing costs in general equilibrium. Our theoretical model is motivated by new empirical patterns from enterprise survey data of the World Bank. Observing that a substantial fraction of the...

This paper develops a new international trade model with capital market imperfections and endogenous borrowing costs in general equilibrium. A key element of our model is that firm heterogeneity arises from the interaction of credit constraints at the firm-level with financial frictions at the...

Infrastructure matters. Markets are designed by market participants for the benefit of market participants and assessed measuring utility to market participants. The natural result is that market structure becomes a tool used by the most powerful market participants to extract rents from the...

The current research assesses the risks commonly attributed to the presence of HFT in the context of different market structures deployed by the U.S. exchanges. In particular, we find that, by design, the so-called “normal” exchanges have the lowest market quality, including the highest...

I study the welfare implications of size-dependent firm regulation policies (SDPs) in the presence of entrepreneurial risks. Although SDP has been considered a source of misallocation, I show that, once entrepreneurial risks are taken into account, SDP can improve efficiency. Quantitatively, I...

This article is the first one that analyzes the choice between crowdfunding and traditional financing as a security design problem. The value of this research comes from several points: 1) the origin of crowdfunding and its features has not been completely explained; 2) crowdfunding regulation is...

Bank market power shapes firm investment and financing dynamics and hence affects the transmission of macroeconomic shocks. Motivated by a secular increase in the concentration of the US banking industry, I study bank market power through the lens of a dynamic general equilibrium model with...

Open banking facilitates data sharing consented by customers who generate the data, with a regulatory goal of promoting competition between traditional banks and challenger fintech entrants. We study lending market competition when sharing banks' customer data enables better borrower screening...
