Why Are Recessions So Hard to Predict? Random Shocks and Business Cycles
Economists are like doctors, not soothsayers. They can't predict recessions, but they can help us understand why one is happening. And that can make all the difference for policymaking.

Fiscal stimulus and distortionary taxation
We quantify the fiscal multipliers in response to the American Recovery and Reinvestment Act (ARRA) of 2009. We extend the benchmark Smets-Wouters (2007) New Keynesian model, allowing for credit-constrained households, the zero lower bound, government capital, and distortionary taxation. The posterior yields modestly positive short-run multipliers around 0.53 and modestly negative long-run multipliers around -0.36. We explain the central empirical findings with the help of a simple three equation New Keynesian model with sticky wages and credit-constrained households.

Political Distribution Risk and Aggregate Fluctuations
We argue that political distribution risk is an important driver of aggregate fluctuations. To that end, we document significant changes in the capital share after large political events, such as political realignments, modifications in collective bargaining rules, or the end of dictatorships, in a sample of developed and emerging economies. These policy changes are associated with significant fluctuations in output and asset prices. Using a Bayesian proxy-VAR estimated with U.S. data, we show how distribution shocks cause movements in output, unemployment, and sectoral asset prices. To ...

Alternative Strategies: How Do They Work? How Might They Help?
Several structural developments in the U.S. economy—including lower neutral interest rates and a flatter Phillips curve—have challenged the ability of the current monetary policy framework to deliver on the Federal Open Market Committee’s (FOMC) dual-mandate goals. This paper explores whether makeup strategies, in which policymakers seek to stabilize average inflation around the inflation target over some horizon, could strengthen the FOMC’s ability to fulfill its dual mandate. The quantitative analysis discussed here suggests that credible makeup strategies may provide some moderate ...

Fiscal stimulus and distortionary taxation
We quantify the fiscal multipliers in response to the American Recovery and Reinvestment Act of 2009. We extend the benchmark Smets-Wouters New Keynesian model (Smets and Wouters, 2007), allowing for credit-constrained households, the zero lower bound, government capital, and distortionary taxation. The posterior yields modestly positive short-run multipliers around 0.52 and modestly negative long-run multipliers around -0.42. The multiplier is sensitive to the fraction of transfers given to credit-constrained households, the duration of the zero lower bound, and the capital. The stimulus ...

Partisanship and Fiscal Policy in Economic Unions: Evidence from U.S. States
In economic unions the fiscal authority consists not of one, but many governments. We analyze whether partisanship of state-level politicians affects federal policies, such as fiscal stimulus in the U.S. Using data from close elections, we find partisan differences in the marginal propensity to spend federal transfers: Republican governors spend less. This partisan difference has tended to increase with measures of polarization. We quantify the aggregate effects in a New Keynesian model of Republican and Democratic states in a monetary union: Lowering partisan differences to levels ...

Politics and Income Distribution
We take a closer look at how political reforms affect labor’s share of national income.

The Role of Startups for Local Labor Markets
We investigate the dynamic response of local U.S. labor markets to increased job creation by new firms and compare the effects to overall labor demand shocks. To account for both dynamic and spatial dependence we develop a spatial panel VAR that builds on recent advances in the VAR literature to identify structural shocks using external instruments. We find that startup shocks have a small but persistent effect on local employment through population growth. Population growth, in turn, is largely driven by immigration. We also investigate how the responses differ by local characteristics such ...

Refining Set-Identification in VARs through Independence
Identification in VARs has traditionally mainly relied on second moments. Some researchers have considered using higher moments as well, but there are concerns about the strength of the identification obtained in this way. In this paper, we propose refining existing identification schemes by augmenting sign restrictions with a requirement that rules out shocks whose higher moments significantly depart from independence. This approach does not assume that higher moments help with identification; it is robust to weak identification. In simulations we show that it controls coverage well, in ...

Accounting for the Sources of Macroeconomic Tail Risks
Using a multi-industry real business cycle model, we empirically examine the microeconomic origins of aggregate tail risks. Our model, estimated using industry-level data from 1972 to 2016, indicates that industry-specific shocks account for most of the third and fourth moments of GDP growth.
