I study the impact of macro policies/climate policies on firms, entrepreneurs, and the macro-economy.
Working Papers:
Taxation and Entrepreneurship in the United States, SSRN Link,
Revised and Resubmitted, American Economic Journal: Macroeconomics, 2025
with Hans Holter (U. of Oslo, Delaware, and Nova) and Serhiy Stepanchuk (U. of Southampton)
Summary: This paper studies the effects of income taxation on entrepreneurship, both empirically and in a structural macro model with entrepreneurial choice.
Foreign Price Shocks, Production Networks, and Monetary Policy, Working paper, SSRN Link,
with Zhesheng Qiu (City U of Hong Kong), Le Xu (Shanghai Jiao Tong U), Francesco Zanetti (Oxford U)
Revised and Resubmitted, Journal of Monetary Economics, 2025
Summary: In an open economy with production networks, Monetary policy differs from standard ones to best reduce inefficiency. Sectoral import and export behaviors, and their propagations via input-output linkages, are critical. Why? A sector's policy weight should be smaller when its downstream sectors import intensively, as that sector contributes less to domestic output; likewise for sectors that intensively export (directly or indirectly through networks), since their distortions matter less to domestic welfare. Notable examples are those "export processing" sectors.
Allocative Efficiency of Green Finance Instruments, SSRN Link,
with Kai Li (Peking U), Chenjie Xu (SHUFE)
Summary: We provide a framework with heterogeneous firms and financial frictions to study the efficiency of different green instruments.
We show it is important to consider the equilibrium allocation effects: for example, Carbon tax may increase Total emissions in our framework but otherwise hard to understand.
Forecasting GDP Growth Rates: A Large Panel Micro Data Approach,
with Yumeng Cui (CUFE), Yongmiao Hong (University of Chinese Academy of Sciences), Naijing Huang (CUFE)
Revise and Resubmit, Management Science, 2025
Summary: We propose a novel micro-forecasting approach, using a large panel of individual firms' accounting earnings from corporate financial reports to forecast GDP.
Do Asset Prices Help Predict Inflation? Evidence from Individual Stock Prices,
with Yumeng Cui (CUFE), Yongmiao Hong (University of Chinese Academy of Sciences), Naijing Huang (CUFE)
Revise and Resubmit, Journal of Business & Economic Statistics, 2024
Summary: Using a large panel of firm-level stock prices and applying machine learning techniques, we demonstrate that individual stock prices significantly enhance the accuracy of inflation forecasts for the macroeconomy, comparing to the literature (such as Stock and Watson (2003, 1989, 1999)).
Leasing, Pecuniary Externality, and Aggregate Efficiency, SSRN Link,
with Kai Li (Peking U), Yiming Xu (Cambridge U)
Summary: For the first time, we study the impact of capital leasing options for firms, beyond capital purchasing, on inefficiency in competitive equilibrium.
We show leasing almost restores the second best!
Publications:
Quantifying the Macroeconomic Impact of Credit Expansions, SSRN Link,
with Corina Boar (NYU), Matthew Knowles (Cologne) and Kjetil Storesletten (Minnesota)
International Economic Review, 2025, forthcoming
Summary: Using banking deregulations in the US as natural experiments, we quantify different channels when credit market conditions change by building and estimating
a Heterogenous-Firm-New-Keynesian Model.
Limited Firm Insurance and Aggregate Implications,
single-authored, Management Science, 2025, Volume 71, Issue 7, July 2025, Pages iv-vi, 5419-6318
Published PDF Published Online Link SSRN Link for the latest version, 05/2024. Working Paper
Summary: little is known about the impacts of financial shocks on firms' insurance to workers and in turn the aggregate implications.
Income Volatility and Portfolio Choices, Review of Economic Dynamics, Volume 44, April 2022, Pages 65-90
with Yongsung Chang (Seoul National U.), Jay H. Hong (Seoul National U.), Marios Karabarbounis (Richmond Fed), Tao Zhang (Frisch data center)
[Published Version PDF Link, Working Paper, Online Appendix], 2022.
Summary: Using administrative data from Norway, we identify the impact of idiosyncratic income volatility shocks on portfolios. A new quantitative structural model, with "shocks to the second moment", is proposed to account for the findings and investigate welfare implications.
Macroeconomic and Distributional Effects of Mortgage Guarantee Programs for the Poor,
with Jiseob Kim (Yonsei), Journal of Economic Dynamics and Control, 87 (2018), 124–151
[Published Version PDF Link, Working Paper]
Summary: Using survey of consumer finance data (1989-2013) and based on a quantitative model, we find that those explicit government guarantee programs (e.g., FHA, VA, RHS) essentially provide insurance and redistribution only within low-income and low-asset households, and the unintended GE effects may hurt other home buyers.
Debt Market Friction, Firm-specific Knowledge Capital Accumulation and Macroeconomic Implications,
single-authored, Review of Economic Dynamics, 26 (2017), 19–39
[Published Version PDF Link, Working Paper, Online Appendix]
Summary: Compustat data suggests that debt market frictions affect firm-specific knowledge capital accumulation and output. Therefore, it provides a rationale for policy intervention.
