In response to debt crises, policy makers often feature Collective Action Clauses (CACs) in sovereign bonds among the pillars of international financial architecture. However, the content of official pronouncements about CACs suggests that CACs are more like doorknobs: a process tool with...

The COVID-19 pandemic causes sharp reductions in economic output and sharp increases in government expenditures. This increases the riskiness of sovereign debts, especially in emerging economies. We propose a framework to study debt sustainability. The economy is subject to productivity and...

We introduce a new suite of macroeconomic models that extend and complement the Debt, Investment, and Growth (DIG) model widely used at the IMF since 2012. The new DIG-Labor models feature segmented labor markets, efficiency wages and open unemployment, and an informal non-agricultural sector....

How costly are sovereign debt crises? In this paper we study output losses during sovereign default and debt renegotiation episodes since 1980. In contrast to previous work, we account for the severity of default and not only for its occurrence. Specifically, we distinguish between “hard”...

This paper, prepared for UNCTAD's initiative on responsible sovereign lending and borrowing, considers concrete strategies for implementing the Principles. It draws on studies in soft law and new governance, and on the recent experience in promoting best practices in international finance,...

Post-War conceptions of human rights have evolved independently of long-established theory and practice of property and creditor rights, to the detriment of the development and implementation of human rights law. This chapter attempts to build a first bridge between these two fields of law. It...

This paper studies how financial innovation in sovereign debt markets can increase a country's level of private investment and welfare. I propose a model where public debt has a liquidity purpose for the domestic private sector and is demanded as a saving vehicle by more patient international...

This paper explores the drivers of sovereign defaults in 100 countries over the period 1996-2012. We build a new data set of sovereign defaults and find that default events on local and foreign currency bonds are equally likely. However, governments default under different economic and financial...

I propose a unified model of domestic bank runs, sovereign debt issuance and international reserve accumulation. Banking fragility gives rise to endogenous costs of default that support sovereign debt capacity. It additionally brings about a financial stabilization role for international...

This paper studies optimal levels of borrowing at each point of a given business cycle when default is considered a possible optimal decision. It also searches for parameters that can cause the sustainable equilibrium of different points in the business cycle to become unstable, or nonexistent....
