Publications

  1. "The Real Effects of Brexit on Labor Demand: Evidence from Firm-level Data." (2025).
    Journal of International Economics with Hang Do, Kiet Duong and Toan Huynh.
    Summary: The 2020 Brexit implementation led exposed firms to reduce their workforce by up to 15.7% relative to firms near the Irish border. Our identification strategy hinges on the de facto separation in EU market access between firms in Great Britain and those in Northern Ireland.
  2. "From Russia with Love: International Risk-sharing, Sanctions, and Firm Investments." (2024).
    Economics Letters with Kiet Duong, Toan Huynh, and Anh Phan.
    Summary: Firms connected to sanctioned Russian counterparts use international risk-sharing channels to mitigate the adverse effects of sanctions on investment.
  3. "Housing Wealth Reallocation between Subprime and Prime Borrowers During Recessions." (2022).
    Macroeconomic Dynamics with Ayse Sapci.
    Summary: Recessions redistribute housing wealth from subprime to prime borrowers as tightened credit conditions disproportionately affect lower-quality mortgage holders, both empirically and in an estimated DSGE model.
  4. "Did the American Recovery and Reinvestment Act Help Counties Most Affected by the Great Recession?" (2021).
    Review of Economic Dynamics with Mario J. Crucini.
    Summary: ARRA stimulus spending did reach the counties most affected by the Great Recession, but the relationship between local economic distress and federal funding allocation is weaker than policymakers intended.
  5. "Electrification, Telecommunications, and the Finance-growth Nexus: Evidence from Firm-level Data." (2021).
    Energy Economics with Christopher A. Cotter and Peter L. Rousseau.
    Summary: The effect of financial development on firm-level growth depends on the availability of physical infrastructure. In particular, electrification and telecommunications access condition how effectively firms can capitalize on financial deepening.
  6. "Asymmetric Effects of Sectoral Shifts under Low and High Uncertainty." (2021).
    Economic Inquiry with Kimberly A. Berg.
    Summary: Sectoral shifts induce more depressed economic activity under high uncertainty than under low uncertainty, and these effects are not driven solely by recessions. A two-sector DSGE model with stochastic volatility replicates these asymmetric dynamics.
  7. "Price Flexibility and Output Volatility under Menu Costs." (2020).
    Macroeconomic Dynamics
    Summary: Greater price flexibility does not necessarily translate into lower output volatility in a state-dependent pricing model with menu costs. The relationship between the frequency of price adjustment and aggregate output volatility is nonmonotonic and depends on the size of menu costs.
  8. "International Effects of Stock Market Dispersion." (2020).
    Southern Economic Journal with Jiayu Wu.
    Summary: Cross-sectional dispersion in U.S. equity returns affects international business cycle dynamics. A rise in stock market dispersion leads to a decline in output and trade flows in OECD economies, operating as a distinct transmission channel from aggregate market volatility.
  9. "International Effects of Corporate Tax Cuts on Income Distribution." (2020).
    Review of International Economics with Siraj G. Bawa.
    Summary: Corporate tax cuts widen income inequality both within and across borders through differentiated equity holdings. A multi-country DSGE model calibrated to U.S. and Canadian data shows that lower capital mobility barriers, but not lower trade costs, can alleviate the distributional divergence.
  10. "International Spillovers of U.S. Financial Volatility." (2019).
    Journal of International Money and Finance with Kimberly A. Berg.
    Summary: Exogenous shocks to U.S. financial volatility generate significant spillovers to macroeconomic activity abroad.
  11. "Stock Market Volatility and International Business Cycle Dynamics: Evidence from OECD Economies." (2015).
    Journal of International Money and Finance
    Summary: Stock market volatility is a significant driver of international business cycle co-movement.

Working Papers

  • "State-dependent Distribution Friction and Monetary Policy." (R&R) with Dong (Carl) Cheng.
    Summary: State-dependent distribution frictions weaken the real effects of monetary policy by dampening the consumption response to monetary shocks.
  • "Natural Disasters and Asset Prices: Evidence from Winter Storm Uri." (Under Review) with Dong (Carl) Cheng.
    Summary: Firms with greater ex-ante employment exposure to Winter Storm Uri experienced significantly larger abnormal return declines. The effect is amplified for firms facing high investment adjustment costs, suggesting that asset prices reflect anticipated real frictions in disaster recovery.
  • "Real Effects of Inflation Expectation Uncertainty." (R&R)
    Summary: Household consumption responds negatively to inflation expectation uncertainty in NY Fed survey data. A dynamic model with cognitive discounting of future inflation shows that precautionary saving motives, higher markups, and expected real interest rate distortions jointly amplify the consumption decline.
  • "A Tale of Infrequent but Long-lasting Liquidity Traps." with Kevin X.D. Huang.
    Summary: Both the reduction in liquidity trap duration and the size of the government spending multiplier are hump-shaped in the magnitude of fiscal stimulus. The result emerges from a nonlinear DSGE model with heterogeneous firm productivity, where the efficacy of fiscal intervention depends on the economy's proximity to the zero lower bound.
  • "Growth in a Time of (Projected) Debt." with Jackie McCafferty and Jonathan Wolff.
    Summary: An increase in projected debt reduces growth above a threshold but raises it below. These dynamics arise in an endogenous regime-switching DSGE model where forward-looking agents curtail taxed activities as sovereign debt approaches its fiscal limit.
  • "Sectoral Shifts and Geopolitical Risks." with Kimberly A. Berg.
    Summary: Unexpected geopolitical shocks induce sectoral shifts and output declines, and we show through a two-sector DSGE model that when this reallocation is subdued, the resulting output decline is correspondingly dampened.
  • "Labor Supply, Risk Aversion, and Conflict Uncertainty." with Kiet Duong.
    Summary: Conflict uncertainty negatively affects individuals' willingness to supply labor, using proximity to the 2014 Ukrainian border as a plausibly exogenous proxy. The labor supply response coincides with an increase in perceived risk aversion, framing the labor supply decision as a gamble under conflict-induced uncertainty.
  • "What Matters for the Rise in Trade? Evidence from the African Continental Free Trade Area." with Kiet Duong, Toan Huynh, and Povilas Lastaukas.
    Summary: The AfCFTA signing increased firms' international-sales-to-total-sales ratio by 2.7 percentage points over five years. The gains are concentrated among firms with prior overseas export experience, those in goods-producing sectors, and those with lower capital adjustment costs.
  • "Sanctions and Knowledge Spillovers." with Kiet Duong, Toan Huynh, and Steven Ongena.
    Summary: International sanctions subject Russian patent applications to longer processing times and fewer forward citations in sanctioning countries. Applicants with Kremlin-linked or popular Russian names, as well as those with recent filing history, systematically bypass these delays.
  • "Firm-specific Tax Incentives under Sanctions: Evidence from Russian Tax Authorities." with Kiet Duong and Toan Huynh.
    Summary: Russian firms receiving tax incentives prior to the 2014 sanctions exhibited higher subsequent revenue, profits, and capital expenditures than non-incentivized peers. These benefits accrued predominantly to private firms, displayed no efficiency gains in the military sector, and ultimately crowded out investment by firms that did not receive incentives.
