Corporate Bond Spreads and the Pandemic II: Heterogeneity across Sectors

The COVID-19 pandemic’s effects on firm borrowing costs have been heterogeneous, with some sectors being more affected than others.

Credit and Liquidity Policies during Large Crises

We compare firms’ financials during the Great Financial Crisis (GFC) and COVID-19. While the two crises featured similar increases in credit spreads, debt and liquid assets decreased during the GFC but increased during COVID-19. In the cross-section, leverage was the primary determinant of credit spreads and investment during the GFC, but liquidity was more important during COVID-19. We augment a quantitative model of firm capital structure with a motive to hold liquid assets. The GFC resembled a combination of real and financial shocks, while COVID-19 also featured liquidity shocks. We ...

Seigniorage and Sovereign Default: The Response of Emerging Markets to COVID-19

Monetary policy affects the tradeoffs faced by governments in sovereign default models. In the absence of lump-sum taxation, governments rely on both disortionary taxes and seigniorage to finance expenditure. Furthermore, monetary policy adds a time-consistency problem in debt choice, which may mitigate or exacerbate the incentives to accumulate debt. A deterioration of the terms-of-trade leads to an increase in sovereign-default risk and inflation, and a reduction in growth, which are consistent with the empirical evidence for emerging economies. An unanticipated shock resembling the ...

Policy Rules and Large Crises in Emerging Markets

In response to the COVID-19 pandemic, Latin American countries temporarily suspended rules limiting debt, fiscal and monetary policies. Despite this increase in flexibility, the crisis implied a substantial deterioration of macroeconomic variables (e.g., real GDP declined by 9.5%) and high welfare costs (which we estimate as equivalent to a 13% one-time reduction in non-tradable consumption). This paper studies a sovereign default model with fiscal and monetary policies to assess the policy response and evaluate the gains from flexibility in times of severe distress.

Macroeconomic Implications of Uniform Pricing

We compile a new database of grocery prices in Argentina, with over 9 million observations per day. We find uniform pricing both within and across regions?i.e., product prices almost do not vary within stores of a chain. Uniform pricing implies that prices would not change with regional conditions or shocks, particularly so if chains operate in several regions. We confirm this hypothesis using employment data. While prices in stores of chains operating almost exclusively in one region do react to changes in regional employment, stores of chains that operate in many regions do not seem to ...

The Impact of Racial Segregation on College Attainment in Spatial Equilibrium

This paper seeks to understand the forces that maintain racial segregation and the Black-White gap in college attainment, as well as their interactions with place-based policy interventions. We incorporate race into an overlapping-generations spatial-equilibrium model with parental investment and neighborhood spillovers. Race matters due to: (i) a Black-White wage gap, (ii) amenity externalities—households care about their neighborhood’s racial composition—and (iii) additional barriers to moving for Black households. We find that these forces account for 71% of the racial segregation ...

Macroeconomic Implications of Uniform Pricing

We compile a new database of grocery prices in Argentina. We find uniform pricing both within and across regions—i.e., prices almost do not vary within stores of a chain. In line with uniform pricing, prices in stores of chains operating in one region react to changes in regional employment, while prices in multi-region chains do not. Using a quantitative regional model with multi-region firms and uniform pricing, we find a one-half smaller elasticity of prices to a regional than an aggregate shock. This result highlights that some caution may be necessary when using regional shocks to ...

Uniform Pricing Within and Across Regions: New Evidence from Argentina

We compile a new database of grocery prices in Argentina, with over 9 million observations per day. Our main novel inding is that product prices almost do not vary within stores of a chain (i.e., uniform pricing). We also find that prices do not change significantly with regional conditions or shocks, particularly so for chains that operate in many regions. To study the impact of uniform pricing on both consumers and firms, this paper uses a tractable model based on the trade literature. Motivated by our empirical findings, each firm has to set the same price in both regions. Relative to a ...

Stylized Facts on the Organization of Small Business Partnerships

The authors study the internal organization of small business partnerships and focus on the number of owners and ownership structure and the dynamics of these variables. They find that partnerships tend to have a small number of owners with equal distribution of ownership shares. Moreover, while partnerships with equally distributed shares tend to keep this distribution constant, those with unequally distributed shares tend to move toward more equal distribution over time. The authors highlight that these facts are in line with the theory of private information in small business partnerships ...
