State-Dependent Local Projections
Do state-dependent local projections asymptotically recover the population responses of macroeconomic aggregates to structural shocks? The answer to this question depends on how the state of the economy is determined and on the magnitude of the shocks. When the state is exogenous, the local projection estimator recovers the population response regardless of the shock size. When the state depends on macroeconomic shocks, as is common in empirical work, local projections only recover the conditional response to an infinitesimal shock, but not the responses to larger shocks of interest in many ...

The Channels of International Comovement
How does exposure to international markets affect returns and cash flow comovements? Foreign bond owners, lenders, affiliates, investors, customers, and suppliers all transmit country shocks to companies. Most multinationals have many of these exposures simultaneously within the same foreign market. Returns and cash flows of two companies comove when exposed to the same country through the same channel. Within-country exposure through different channels is generally associated with lower comovement, in line with an operational hedging strategy. This evidence can help reconcile how, on ...

Firm Dynamics and Random Search over the Business Cycle
I build a tractable random search model with firm dynamics, on-the-job search, and aggregate shocks. Multi-worker firms make recruitment decisions, choose whether to enter or exit the market, and design wage contracts. Tractability is obtained by showing that, under a set of assumptions on the recruitment technology, the decisions of workers and firms can be expressed in terms of the firms’ current productivity. I introduce a numerical solution method to accommodate aggregate shocks in this environment and show that the model can replicate salient features of both firm-level data on ...

Macroeconomic Responses to Uncertainty Shocks: The Perils of Recursive Orderings
A common practice in empirical macroeconomics is to examine alternative recursive orderings of the variables in structural vector autoregressive (VAR) models. When the implied impulse responses look similar, the estimates are considered trustworthy. When they do not, the estimates are used to bound the true response without directly addressing the identification challenge. A leading example of this practice is the literature on the effects of uncertainty shocks on economic activity. We prove by counterexample that this practice is invalid in general, whether the data generating process is a ...
Journal Article
At the Richmond Fed: Community Conversations
When Tom Barkin became president of the Richmond Fed in 2018, he made it his goal to spend time in every part of the Fifth District to stay well-informed about its communities. (See "Learning From Our District,") One of the ways the Richmond Fed's research department supports this goal is through an event series known as Community Conversations. These are one- or two-day road trips to visit with business and community leaders and learn about an area's challenges and successes.
Working Paper
Monetary Policy with Racial Inequality
I develop a heterogeneous-agent New-Keynesian model featuring racial inequality in income and wealth, and studies interactions between racial inequality and monetary policy. Black and Hispanic workers gain more from accommodative monetary policy than White workers mainly due to higher labor market risks. Their gains are larger also because of a larger proportion of them are hand-to-mouth, while wealthy White workers gain more from asset price appreciation. Monetary and fiscal policies are substitutes in providing insurance against cyclical labor market risks. Racial minorities gain even more ...
