Discount Rates, Debt Maturity, and the Fiscal Theory
with Corhay, Kung, and Morales
This paper examines how the transmission of government portfolio risk arising from maturity operations depends on the stance of monetary/fiscal policy. Accounting for risk premia in the fiscal theory allows the government portfolio to affect expected inflation, even in a frictionless economy. The effects of maturity rebalancing on expected inflation in the fiscal theory depend directly on the conditional nominal term premium, giving rise to an optimal debt-maturity policy that is state-dependent. In a calibrated macrofinance model, we demonstrate that maturity operations have sizable effects on expected inflation and output through our novel risk transmission mechanism.

Micro Uncertainty and Asset Prices
with Herskovic and Kung
Size and value premia comove strongly with one another at low frequencies, but they are both negatively related to long-run movements in the equity premium. We explain these patterns in an investment-based asset pricing model featuring persistent micro and macro uncertainty. Micro uncertainty generates size and value premia waves, while macroeconomic uncertainty produces equity premium waves. The negative correlation between micro and macro uncertainty at low frequencies explains why the equity premium is a long-term hedge for size and value premia. Persistent micro uncertainty is also a source of instability for size and value factors in short samples.

Threats to Central Bank Independence: High-Frequency Identification with Twitter
with Bianchi, Gomez-Cram, and Kung
A high-frequency approach is used to analyze the effects of President Trump’s tweets that criticize the Federal Reserve on financial markets. Identification exploits a short time window around the precise timestamp for each tweet. The average effect on the expected fed funds rate is negative and statistically significant, with the magnitude growing by horizon. The tweets also lead to an increase in stock prices and to a decrease in long-term U.S. Treasury yields. VAR evidence shows that the tweets had an important impact on actual monetary policy, the stock market, bond premia, and the macroeconomy.
