Establishment Size Dynamics in the Aggregate Economy

Why do growth and net exit rates of establishments decline with size? What determines the size distribution of establishments? This paper presents a theory of establishment dynamics that simultaneously rationalizes the basic facts on economy-wide establishment growth, net exit, and size distributions. The theory emphasizes the accumulation of industry-specific human capital in response to industry-specific productivity shocks. It predicts that establishment growth and net exit rates should decline faster with size and that the establishment size distribution should have thinner tails in sectors that use human capital less intensively or physical capital more intensively. In line with the theory, the data show substantial sectoral heterogeneity in U.S. establishment size dynamics and distributions, which is well explained by variation in physical capital intensity.

Recovery Before Redemption: A Theory of Delays in Sovereign Debt Renegotiations

Negotiations to restructure sovereign debts are protracted, taking on average almost 8 years to complete. In this paper we construct a new database (the most extensive of its kind covering ninety recent sovereign defaults) and use it to document that these negotiations are also ineective in both repaying creditors and reducing the debt burden countries face. Specifically, we find that creditor losses average roughly 40 per-cent, and that the average debtor exits default more highly indebted than when they entered default. To explain this apparent large ineciency in negotiations, we present a theory of sovereign debt renegotiation in which delay arises from the same commitment problems that lead to default in the first place. A debt restructuring generates surplus for the parties at both the time of settlement and in the future. However, a creditor’s ability to share in the future surplus is limited by the risk that the debtor will default on the settlement agreement. Hence, the debtor and creditor find it privately optimal to delay restructuring until future default risk is low, even though delay means some gains from trade remain unexploited. We show that a quantitative version of our theory can account for a number of stylized facts about sovereign default, as well as the new facts about debt restructurings that we document in this paper. Finally, we argue that our findings shed light on the existence of delays in bargaining in a wider range of contexts.

Sovereign Theft: Theory and Evidence about Sovereign Default and Expropriation

This paper examines the relationship between default on sovereign borrow- ing and the expropriation of foreign direct investment in both theory and in practice

Private capital flows, capital controls, and default risk

What has been the effect of the shift in emerging market capital flows toward private sector borrowers? Are emerging market capital flows more efficient? If not, can controls on capital flows improve welfare? This paper shows that the answers depend on the form of default risk. When private loans are enforceable, but there is the risk that the government will default on behalf of all residents, private lending is inefficient and capital controls are potentially Pareto-improving. However, when private agents may individually default, capital flow subsidies are potentially Pareto-improving.

External and Public Debt Crises

The recent debt crises in Europe and the U.S. states feature similar sharp increases in spreads on government debt but also show important differences. In Europe, the crisis occurred at high government indebtedness levels and had spillovers to the private sector. In the United States, state government indebtedness was low, and the crisis had no spillovers to the private sector. We show theoretically and empirically that these different debt experiences result from the interplay between differences in the ability of governments to interfere in private external debt contracts and differences in the flexibility of state fiscal institutions.

Theory of Sovereign Debt and Default

This chapter provides a relatively nontechnical survey of theoretical research on the effect of sovereign risk on the market for sovereign debt, with an emphasis on the way sovereign risk constrains the process of financial globalization. After summarizing the legal environment governing sovereign debt, it discusses the forces that encourage repayment of sovereign debt when legal enforcement is ineffective. It then reviews the recent literature that examines the quantitative importance of these forces. It concludes by discussing a range of institutional changes and policy reforms that might act to further reduce the level of sovereign risk and hence strengthen the process of financial globalization.

Strategic Behavior in Sovereign Debt Restructuring: Impact and Policy Responses

The restructuring of sovereign debt is time consuming. For the period since 1970, the time between an initial default on a debt and the final restructuring of that debt has averaged roughly seven years (Pitchford and Wright 2007). These delays show little sign of abating. Argentina’s default of 2000 remains unresolved at the time of writing, and US courts have recently affirmed the use of pari passu clauses to prevent the servicing of new debts while previously issued debt remains in default and hence limits a country’s ability to borrow again.1 Likewise, although Greece used the domestic legislation to promptly restructure privately held bonds issued under Greek law in 2012, a future restructuring involving offcial creditors and foreign law bondholders appears inevitable.2

Insurance in Human Capital Models with Limited Enforcement

This paper develops a tractable human capital model with limited enforceability of contracts. The model economy is populated by a large number of long-lived, risk-averse households with homothetic preferences who can invest in risk-free physical capital and risky human capital. Households have access to a complete set of credit and insurance contracts, but their ability to use the available financial instruments is limited by the possibility of default (limited contract enforcement). We provide a convenient equilibrium characterization that facilitates the computation of recursive equilibria substantially. We use a calibrated version of the model with stochastically aging households divided into 9 age groups. Younger households have higher expected human capital returns than older households. According to the baseline calibration, for young households less than half of human capital risk is insured and the welfare losses due to the lack of insurance range from 3 percent of lifetime consumption (age 40) to 7 percent of lifetime consumption (age 23). Realistic variations in the model parameters have non-negligible effects on equilibrium insurance and welfare, but the result that young households are severely underinsured is robust to such variations.

Debt Statistics a la Carte : Alternative Recipes for Measuring Government Indebtedness

In this note, we apply our same measurement techniques to the debts of Greece, Ireland and Portugal and show that plausible alternative measures of indebtedness suggest that Greece is anywhere from as much as 50% more indebted, to as little as half as indebted as either Portugal or Ireland. We argue that most reasonable measures imply that Greece is far less indebted than is commonly reported, and that indebtedness levels across these three economies are roughly similar.

Interpreting the Pari Passu Clause in Sovereign Bond Contracts: It's All Hebrew (and Aramaic) to Me

In this comment, we take a helicopter tour of the history of notions of ?equality? and ?justice? in sovereign debt restructuring in particular, and in the division of property more generally, and show that these concerns have existed for centuries, if not millennia. We argue that the issue at stake in the interpretation of the pari passu clause is not so much the treatment of holders of identical claims?it is now customary to treat them identically?but whether the holders of different claims should be treated differently. We show that exists a customary ?principle of differentiation? that allows creditors with claims that differ in specific ways to be treated preferentially. One of these specific differences concerns debts that have been reduced in value during a previous debt restructuring or default, and based on this principle we conclude that the New York court has, if not completely misinterpreted the meaning of the pari passu clause, then at least misapplied it.
