We study the effects of fiscal policy in response to the COVID-19 pandemic at the firm, sector, country and global levels. First, we estimate the impact of COVID-19 and policy responses on small and medium-sized enterprise (SME) business failures. We combine firm-level financial data from 50...

We study the effects of financial frictions on firm exit when firms face large liquidity shocks. We develop a simple model of firm cost-minimization that introduces a financial friction that limits firms' borrowing capacity to smooth temporary shocks to liquidity. In this framework, firm exit...

We estimate the impact of the COVID-19 crisis on business failures among small and medium-size enterprises (SMEs) in seventeen countries using a large representative firm-level database. We use a simple model of firm cost minimization and measure each firm's liquidity shortfall during and after...

This paper assesses the prospects of a 2021 time bomb in small and medium-sized enterprises (SME) failures triggered by the generous support policies enacted during the 2020 COVID-19 crisis. Policies implemented in 2020, on their own, do not create a 2021 time bomb for SMEs. Rather, business...

To what extent do national borders and national currencies impose costs that segment markets across countries? To answer this question the authors use a dataset with product-level retail prices and wholesale costs for a large grocery chain with stores in the United States and Canada. They...

We investigate the effects of input variety creation and destruction on both micro- and macroeconomic outcomes using detailed data from Belgium. Our microeconomic analysis establishes that the elasticity of downstream firms' marginal cost to supplier separation captures the area under the input...

The authors show that even when the exchange rate cannot be devalued, a small set of conventional fiscal policy instruments can robustly replicate the real allocations attained under a nominal exchange rate devaluation in a standard New Keynesian open economy environment. They perform the...

Real risk-free interest rates have trended down over the past 30 years. Puzzlingly in light of this decline, (1) the return on private capital has remained stable or even increased, creating an increasing wedge with safe interest rates; (2) stock market valuation ratios have increased only...

The recent unravelling of the Eurozone's financial integration raised concerns about feedback loops between sovereign and banking insolvency. The paper provides a theory of the feed backloop that allows for both domestic bailouts of the banking system and sovereign debt forgiveness by...
