We study e-commerce across 47 economies and 26 industries during the COVID-19 pandemic using aggregated and anonymized transaction-level data from Mastercard, scaled to represent total consumer spending. The share of online transactions in total consumption increased more in economies with...

We construct novel text-based measures of firm-level cyber risk exposure based on quarterly earnings calls of 12,000+ firms from 85 countries over 20+ years. We categorize each cyber-related discussion into topics that capture sentiment, monetary loss, country names, etc. We document new facts...

It has long been recognized that a country's tariffs are the endogenous outcome of a rent-seeking game whose equilibrium reflects national institutions. Thus, the structure of tariffs across industries provides insights into how institutions, as reflected in tariff policies, affect long-term...

Aggregate price levels are positively related to GDP per capita across countries. We propose a mechanism that rationalizes this observation through sectorial differences in intermediate input shares. As aggregate productivity and income grow, so do wages relative to intermediate input prices,...

While there has been significant research to explore the determinants (and frictions) of foreign direct investment (FDI), past literature primarily focuses on country-wide FDI patterns with little examination of sectoral heterogeneity in FDI. Anecdotally, there is substantial sectoral...

Using a new dataset on sectoral credit exposures covering financial and non-financial sectors in 115 economies over the period 1940-2014, we document the following evidence that corporate debt plays a key role in explaining boom-bust cycles, financial crises, and slow macroeconomic recoveries:...

Electrification of transportation and buildings to reduce greenhouse gas (GHG) emissions requires massive switching from natural gas and refined petroleum products. All three end-use energy sources are mispriced due in part to the unpriced pollution they emit. Natural gas and electricity...

I generalize a benchmark model of directed technical change in order to reconcile it with the historical experience of energy transitions. I show that the economy becomes increasingly locked-in to the dominant sector when machines and energy resources are substitutes, but a transition away from...

There has been a widespread displacement of coal by natural gas as space heating and cooking technology in Turkey in the last two decades, triggered by the deployment of natural gas networks. In this paper, we examine the impact of this development on mortality among adults and the elderly. Our...

We document the consequences of real exchange rate movements for the employment, hours, and hourly earnings of workers in manufacturing industries across individual states. Exchange rates have statistically significant wage and employment implications in these local labor markets. The importance...
