We analyze how trade affects aggregate volatility using a multi-country, multiindustry, and multi-destination framework. We decompose aggregate output growth risk into destination risk, origin risk, and idiosyncratic risk (and their covariances). We then use this framework to run counterfactuals...

We develop an empirical framework that allows us to account for producer-country, industry, and demand shocks as drivers of volatility at the industry level in open economies. Our methodology separately accounts for demand shocks originating in the home and foreign markets. Using a panel of...

I revisit Reimer (2006), and Trefler and Zhu (2005, 2006) (RTZ) tests of the Vanek proposition in the presence of international differences in production techniques and global production sharing. In this framework, knowing the bilateral details of each country’s input-output structure is key...

Chapter 1 of this thesis revisits Reimer (2006), and Trefler and Zhu (2005, 2006) (RTZ) tests of the Vanek proposition in the presence of international differences in production techniques and global production sharing. In this framework, knowing the bilateral details of each country's...
