Sovereign Risk and Fiscal Information: A Look at the U.S. State Default of the 1840s
This paper examines how newspaper reporting affects government bond prices during the U.S. state default of the 1840s. Using unsupervised machine learning algorithms, the paper first constructs novel ``fiscal information indices'' for state governments based on U.S. newspapers at the time. The impact of the indices on government bond prices varied over time. Before the crisis, the entry of new western states into the bond market spurred competition: more state-specific fiscal news imposed downward pressure on bond prices for established states in the market. During the crisis, more ...

Time-Inconsistent Optimal Quantity of Debt
A key property of the Aiyagari-type heterogeneous-agent models is that the equilibrium interest rate of public debt lies below the time discount rate. This fundamental property, however, implies that the Ramsey planner's fiscal policy may be time-inconsistent because the forward-looking planner would have a dominate incentive to issue plenty of debt, such that all households are fully self-insured against idiosyncratic risk whenever the interest rate of government borrowing is lower than the household time discount rate. But such a full self-insurance allocation may be paradoxical because, to ...

Financing Workforce Development in a Devolutionary Era
Workforce development financing has changed significantly over the last 25 years. In 2008, federal funding for the traditional workforce development system was 83 percent lower in real terms than it had been in 1980. As the federal system plays a smaller role in workforce development financing, the job training landscape better represents a “marketplace” where students and job seekers use federal training vouchers and grant and student loan money from various sources, primarily the Higher Education Act’s Pell Grant and Federal Student Loan programs. Additionally, increasing volatility ...

Optimal Fiscal Policies under Market Failures
The aggregate capital stock in a nation can be overaccumulated for many different reasons. This paper studies which policy or policy mix is more effective in achieving the socially optimal (modified golden rule) level of aggregate capital stock in an infinite-horizon heterogeneous-agents incomplete-markets economy where capital may be over-accumulated for two distinct reasons: (i) precautionary savings and (ii) production externalities. By solving the Ramsey problem analytically along the entire transitional path, we show that public debt and capital taxation play very distinct roles in ...

The Macroeconomic Effects of the Tax Cuts and Jobs Act
This paper studies the macroeconomic effects of seven key TCJA provisions, including the tax cuts for individuals and businesses, the bonus depreciation of equipment, the amortization of R&D expenses, and the limits on interest deductibility. I use a dynamic general equilibrium model with interest deductibility and accelerated depreciation. I find that, initially, the tax reform had a small positive impact on output and investment. In the medium term, however, the effect on output will diminish, and the effect on investment will turn negative. The tax reform will depress investment in R&D. ...

The Determination of Public Debt under both Aggregate and Idiosyncratic Uncertainty
We analyze the Ramsey planner's decisions to finance stochastic public expenditures under incomplete insurance markets for idiosyncratic risk. We show analytically that whenever the market interest rate lies below the time discount rate, the Ramsey planner has a dominant incentive to increase debt to meet the private sector's demand for full self-insurance regardless of the relative size of aggregate shocks---suggesting a departure from tax smoothing. However, if a full self-insurance Ramsey allocation is infeasible in the absence of a government debt limit, an interior or bounded Ramsey ...

Implementing the Modified Golden Rule? Optimal Ramsey Capital Taxation with Incomplete Markets Revisited
What is the prescription of Ramsey capital taxation in the long run? Aiyagari (1995) addressed the question in a heterogeneous-agent incomplete-markets (HAIM) economy, showing that a positive capital tax should be imposed to implement the so-called modified golden rule (MGR). This paper revisits the long-standing issue. Working with commonly used separable isoelastic preferences, we show (i) the multiplier on the resource constraint of the Ramsey problem must diverge in the limit if a Ramsey steady state exists, (ii) there is no Ramsey steady state when the elasticity of intertemporal ...

Did Tax Cuts and Jobs Act Create Jobs and Stimulate Growth? Early Evidence Using State-Level Variation in Tax Changes
The Tax Cuts and Jobs Act (TCJA) of 2017 is the most extensive overhaul of the U.S. income tax code since the Tax Reform Act of 1986. Existing estimates of TCJA’s economic impact are based on economic projections using pre-TCJA estimates of tax effects. Following recent pioneering work of Zidar (2019), I exploit plausibly exogenous state-level variation in tax changes and find that an income tax cut equaling 1 percent of GDP led to a 1 percentage point higher nominal GDP growth and about 0.3 percentage point faster job growth in 2018.

The Determination of Public Debt under both Aggregate and Idiosyncratic Uncertainty
We use an analytically tractable, heterogeneous-agent incomplete-markets model to show that the Ramsey planner's decision to finance stochastic public expenditures implies a departure from tax smoothing and an endogenous mean-reverting force to support positive debt growth despite the government's precautionary saving motives. Specifically, the government's attempt to balance the competing incentives between its own precautionary saving (tax smoothing) and households' precautionary saving (individual consumption smoothing)---even at the cost of extra tax distortion---implies an endogenous, ...
