A number of recent papers have argued that US firms exert increasing market power, as measured by their markups of price over marginal cost. I review three of the main approaches to estimating economy-wide markups and show that all are based on the hypothesis of firm cost-minimization. Yet...

It has long been argued that cyclical fluctuations in labor and capital utilization and the presence of overhead labor and capital are important for explaining procyclical productivity. Here I present two simple and direct tests of these hypotheses, and a way of measuring the relative importance...

This paper presents an aggregate demand-driven model of business cycles that provides a new explanation for the procyclicality of productivity, and simultaneously predicts large welfare losses from monetary non-neutrality. The key features of the model are an input- output production structure,...

FinTech online lending to consumers has grown rapidly in the post-crisis era. As argued by its advocates, one key advantage of FinTech lending is that lenders can predict loan outcomes more accurately by employing complex analytical tools, such as machine learning (ML) methods. This study...

Using supervisory data on small and mid-sized nonfinancial enterprises (SMEs), we find that those SMEs with higher leverage faced tighter constraints in accessing bank credit after the COVID-19 outbreak in spring 2020. Specifically, SMEs with higher pre-COVID leverage obtained a smaller volume...

The Main Street Lending Program (MSLP) was established by the Federal Reserve to supply credit to small and, especially, midsize businesses so they could weather COVID-19-induced disruptions. This study uses Dun & Bradstreet (D&B) data on the financial condition and overall viability of firms to...

This study explores the mechanisms explaining the large, persistent effect of the 10-day funding delay in the 2020 Paycheck Protection Program (PPP) on employment recovery during the COVID-19 pandemic, as estimated by Doniger and Kay (2021). We find that the top 1 percent of urban counties by...
