We characterize how firms structure supply chains under climate risk. Using new data on the universe of firm-to-firm transactions from an Indian state, we show that firms diversify sourcing locations, and suppliers exposed to climate risk charge lower prices. Our event-study analysis finds that...

Emerging countries exhibit volatile fiscal policies and frequent sovereign debt crises, that significantly diminish the well-being of their citizens. International advisors typically suggest developed-world solutions as a remedy. We argue that the root of the problem lies in the institutional...

Intense US-China commercial rivalry is quantified in this paper with novel non-parametric relative resistance sufficient statistics. The accounting method minimizes the demand specification error variance in revealed resistances. China's manufacturing seller incidence falls (seller price rises)...

We study the impact of the Covid-19 pandemic on Euro Area inflation and how it compares to the experiences of other countries, such as the United States, over the two-year period 2020-21. Our model-based calibration exercises deliver four key results: 1) Compositional effects - the switch from...

The last two centuries witnessed the rise and fall of empires. We construct a model which rationalises this in terms of the changing trade gains from empires. In the model, empires are arrangements that reduce trade cost between an industrial metropole and the agricultural periphery. During...

A prominent explanation for why trade is not free is politicians' desire to protect some of their constituents at the expense of others. In this paper we develop a methodology that can be used to reveal the welfare weights that a nation's import tariffs implicitly place on different groups of...

Surveys are an essential approach for eliciting otherwise invisible factors such as perceptions, knowledge and beliefs, attitudes, and reasoning. These factors are critical determinants of social, economic, and political outcomes. Surveys are not merely a research tool. They are also not only a...

We discuss the impacts of the Russian invasion on Ukrainian science. Using newly collected data, we show that the war has already had significant effects on science in Ukraine: research papers produced by Ukrainian scientists declined by about 10%, approximately 5% of the most prolific...

Monetary rules may have a large effect on the outcome of trade wars if central banks target the CPI inflation rate or more generally changes in the relative price of traded goods. We lay out a two-country open-economy model with sticky prices where countries engage in trade wars. In the presence...

Empirical work finds that flows of investments from the U.S. and other high income countries to emerging markets increase during times of quantitative easing by the U.S. Federal Reserve, and the reverse movement occurs under quantitative tightening. We offer new evidence to confirm these...
