Sanctions are measures that one party (the sender) takes to influence the actions of another (the target). Sanctions, or the threat of sanctions, have been used, for example, by creditors to get a foreign sovereign to repay debt or by one government to influence the human rights, trade, or...

The COVID-19 pandemic as well as the Russian invasion of Ukraine have had profound effects on the global energy landscape, with some of the longer-lasting effects still unfolding. This paper discusses how these events have reshaped the supply side of the global oil market by focusing on...

Theoretical models have suggested that sanctions may be important for enforcing sovereign debt contracts (Bulow and Rogoff, 1989a, 1989b). This paper examines the role of sanctions in promoting debt repayment during the classical gold standard period. We analyze a wide range of sanctions...

In this paper we first trace the changing nature of banking, currency and debt crises from the last century to the present. Each type of crisis has transmogrified in the presence of official intervention and the creation of a safety net. A similar pattern is observed for international rescue...

We propose a simple measure of de facto financial market integration based on a factor model of monthly equity returns, which can be computed back to the first era of financial globalization for 17 countries. Global financial market integration follows a “swoosh” shape – i.e. high...

Ad blockers allow Internet users to obtain information without generating ad revenue for site owners; and by 2016 they were used by roughly a quarter of site visitors. Given the ad-supported nature of much of the web, ad blocking poses a threat to site revenue and, if revenue losses undermine...

We meta-analyze for impact and cost-effectiveness 94 studies from 47 conditional cash transfer (CCT) programs in low- and middle-income countries worldwide, focusing on educational outcomes that include enrollment, attendance, dropout and school completion. To conceptually guide and interpret...

International differences in teacher quality are commonly hypothesized to be a key determinant of the large international student performance gaps, but lack of consistent quality measures has precluded testing this. We construct country-level measures of teacher cognitive skills using unique...

We ask whether recent changes in monetary policy due to the financial crisis will be temporary or permanent. We present evidence from two surveys—one of central bank governors, the other of academic specialists. We find that central banks in crisis countries are more likely to have resorted to...
