Pass-through of Competitors' Exchange Rates to US Import and Producer Prices
Journal of International Economics  (March 2017) [journal version (gated)]    [accepted manuscript (downloadable)]
(also World Bank Policy Research Working Paper 7926 [link to working paper] [online appendix])
        This paper shows that in theory and BLS microdata, the prices of imported goods respond to the exchange rates (ER) of the producer's foreign competitors. In contrast, standard models have no role for competitors' ERs. Excluding the effects of competitors' exchange rates typically biases upwards estimates of bilateral exchange rate pass-through because competitors' ERs and bilateral ERs are positively correlated. A multi-country version of Atkeson and Burstein's (2008) industry aggregation model is able to explain a sizable proportion of pass-through of competitors' exchange rates to import prices, and also predicts pass-through of foreign competitors' prices and pass-through of competitors' ERs to US producer prices --- both of which are supported in the data. The results suggest that pass-through will be larger for ER movements shared by a greater fraction of foreign competitor countries.

When is the Government Transfer Multiplier Large? (joint with Eric Giambattista)
European Economic Review (November 2017) [journal version (gated)] [accepted manuscript (downloadable)
(also World Bank Policy Research Working Paper 8184)  [link to working paper] [online appendix] )
        Transfers to individuals were a larger part of the 2009 US stimulus package than government purchases. Using a two-agent New Keynesian model, we show analytically that the multiplier on targeted transfers to financially constrained households is (i) larger than the purchase multiplier if the zero lower bound (ZLB) binds and (ii) is more sensitive to degree of monetary accommodation of inflation. Targeted transfers provide the same boost to demand as purchases, but lower aggregate supply relative to purchases, as those receiving transfers want to work less. When the aggregate demand curve inverts --- such as when the ZLB binds --- the extra inflation from lower supply boosts the multiplier. We show this result also holds quantitatively in a medium-scale version of the model.

The impact of monetary policy on financial markets in small open economies: more or less effective during the financial crisis? (with Arief Ramayandi and Hsiao Chink Tang) 
Journal of Macroeconomics 44 (June 2015), 60-70 [journal version (gated)]  [accepted manuscript (downloadable)] [online appendix]
        This paper estimates the impact of monetary policy on exchange rates and stock prices of eight small open economies: Australia, Canada, the Republic of Korea, New Zealand, the United Kingdom, Indonesia, Malaysia, and Thailand. On average across these countries in the full sample, a one percentage point surprise rise in official interest rates leads to a 1% appreciation of the exchange rate and a 0.5–1% fall in stock prices, with somewhat stronger effects in OECD countries than non-OECD countries (though differences are sometimes not significant). We find little robust evidence of a change in the effect of monetary policy surprises during the recent financial crisis.

Cross-region transfers in a monetary union: Evidence from the US and implications for Europe Latest version: Dec 2017 [link to paper] [online appendix] Reject/Resubmit at the American Economic Review
        Federal transfers to individuals are countercyclical, vary greatly across US states, and are often given credit for helping stabilize regional economies. This paper estimates the effects of these transfers using plausibly exogenous regional variation in recent temporary stimulus packages and earlier permanent social security increases. I find that states receiving larger transfers tend to grow faster contemporaneously, with greater multipliers for permanent transfers. Results are consistent with an open-economy New Keynesian model. Despite this, a counterfactual “transfer union” in Europe (which currently lacks equivalent cross-country transfers) only generates modest gains in regional stabilization, especially when compared with locally-financed countercyclical transfers.

Shrinking Dictators: Assessing the Growth Contribution of Individual National Leaders (joint with William Easterly) Latest: October 2018 [link to paper[online appendix
(previous title "How Much Do Leaders Explain Growth? An Exercise in Growth Accounting" March 2015 [link]) 
           Individual national leaders – especially autocratic ones – often claim credit for high rates of economic growth while they are in office (and draw criticism for slow growth). This paper is the first to develop a rigorous methodology to estimate the growth contribution of individual leaders (and calculate its precision). We find few leaders have a statistically significant contribution: even if leaders affect growth in general, it is hard to separate good-for-growth and bad-for-growth leaders. As average growth rates are misleading about leaders’ true contribution, many significant leaders are surprises. Moreover, autocratic leaders are no more likely to be significant than democrats.

Too Busy to Fight? Harvest and the Seasonality of Conflict (joint with Jenny Guardado) Latest version: July 2017 [link to paper] [appendix] (old title: The Seasonality of Conflict)
        This paper exploits the seasonality of agricultural labor markets to estimate the effect of changes in the returns to working on conflict intensity. Using a dynamic model of labor supply, we first show theoretically that exogenous, anticipated, and transitory changes in labor demand due to harvest are better able to capture the effects of changes in the opportunity cost of conflict relative to other shocks commonly analyzed in the literature. This is because harvest shocks hold constant other dynamic drivers of conflict which can bias empirical estimates and obscure the strength of the opportunity cost mechanism. Our empirical identification strategy exploits exogenous sub-national variation in the timing and intensity of harvest driven by local climatic conditions. Using data from several conflict settings – Afghanistan, Iraq, and Pakistan – our results show that the onset of harvest usually leads to a statistically significant reduction in the share of monthly insurgent attacks.
