Just How Important Are New Businesses?
New businesses are major job generators, so disappointing trends in firm formation have raised concern. Thorsten Drautzburg discusses why at least some of the worry might be misplaced.

A Structural Approach to Combining External and DSGE Model Forecasts
This note shows that combining external forecasts such as the Survey of Professional Fore casters can significantly increase DSGE forecast accuracy while preserving the interpretability in terms of structural shocks. Applied to pseudo real-time from 1997q2 onward, the canonical Smets and Wouters (2007) model has significantly smaller forecast errors when giving a high weight to the SPF forecasts. Incorporating the SPF forecast gives a larger role to risk premium shocks during the global financial crisis. A model with financial frictions favors a larger weight on the DSGE model forecast.

Entrepreneurial tail risk: implications for employment dynamics
New businesses are important for job creation and have contributed more than proportionally to the expansion in the 1990s and the decline of employment after the 2007 recession. This paper provides a framework for analyzing determinants of business creation in a world where new business owners are exposed to idiosyncratic risk due to initial imperfect diversification. This paper uses this framework to analyze how entrepreneurial risk has changed over time and how this has affected employment in the US. Conditions are provided under which entrepreneurial risk can be identified using micro data ...

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.

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 ...

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.

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 ...

Bargaining Shocks and Aggregate Fluctuations
We argue that social and political risk causes significant aggregate fluctuations by changing bargaining power. 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. Using a Bayesian proxy-VAR estimated with U.S. data, we show how distribution shocks cause movements in output and unemployment. To quantify the ...

Polarized Contributions but Convergent Agendas
The political process in the United States appears to be highly polarized: Data show that the political positions of legislators have diverged substantially, while the largest campaign contributions come from the most extreme donor groups and are directed to the most extreme candidates. Is the rise in campaign contributions the cause of the growing political polarization? In this paper, we show that, in standard models of campaign contributions and electoral competition, a free-rider problem among potential contributors leads naturally to polarization of campaign contributors but without any ...

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 ...
