A large body of research has investigated whether physicians overuse care. There is less evidence on whether, for a fixed level of spending, doctors allocate resources to patients with the highest expected returns. We assess both sources of inefficiency, exploiting variation in rates of negative imaging tests for pulmonary embolism. We document enormous across-doctor heterogeneity in testing conditional on patient population, which explains the negative relationship between physicians' testing rates and test yields. Furthermore, doctors do not target testing to the highest risk patients, reducing test yields by one-third. Our calibration suggests misallocation is more costly than overuse.

We explore the in- and out-of-sample robustness of tests for choice inconsistencies based on parameter restrictions in parametric models, focusing on tests proposed by Ketcham, Kuminoff, and Powers (2016). We argue that their nonparametric alternatives are inherently conservative with respect to detecting mistakes. We then show that our parametric model is robust to KKP's suggested specification checks, and that comprehensive goodness of fit measures perform better with our model than the expected utility model. Finally, we explore the robustness of our 2011 results to alternative normative assumptions highlighting the role of brand fixed effects and unobservable characteristics.

We study choice over prescription insurance plans by the elderly using government administrative data to evaluate how these choices evolve over time. We find large "foregone savings" from not choosing the lowest cost plan that has grown over time. We develop a structural framework to decompose the changes in "foregone welfare" from inconsistent choices into choice set changes and choice function changes from a fixed choice set. We find that foregone welfare increases over time due primarily to changes in plan characteristics such as premiums and out-of-pocket costs; we estimate little learning at either the individual or cohort level.

We analyze securities trading by banks during the crisis and the associated spillovers to the supply of credit. We use a proprietary data set that has the investments of banks at the security level for 2005–2012 in conjunction with the credit register from Germany. We find that—during the crisis—banks with higher trading expertise (trading banks) increase their investments in securities, especially in those that had a larger price drop, with the strongest impact in low-rated and long-term securities. Moreover, trading banks reduce their credit supply, and the credit crunch is binding at the firm level. All of the effects are more pronounced for trading banks with higher capital levels. Finally, banks use central bank liquidity and government subsidies like public recapitalization and implicit guarantees mainly to support trading of securities. Overall, our results suggest an externality arising from fire sales in securities markets on credit supply via the trading behavior of banks.

Charter takeovers are traditional public schools restarted as charter schools. We develop a grandfathering instrument for takeover attendance that compares students at schools designated for takeover with a matched sample of students attending similar schools not yet taken over. Grandfathering estimates from New Orleans show substantial gains from takeover enrollment. In Boston, grandfathered students see achievement gains at least as large as the gains for students assigned charter seats in lotteries. A non-charter Boston turnaround intervention that had much in common with the takeover strategy generated gains as large as those seen for takeovers, while other more modest turnaround interventions yielded smaller effects.

We study employers' perceptions of the value of postsecondarydegrees using a field experiment. We randomly assign the sectorand selectivity of institutions to fictitious resumes and apply to realvacancy postings for business and health jobs on a large online jobboard. We find that a business bachelor's degree from a for-profitonline institution is 22 percent less likely to receive a callback thanone from a nonselective public institution. In applications to healthjobs, we find that for-profit credentials receive fewer callbacks unlessthe job requires an external quality indicator such as an occupationallicense.

The announcement of Timothy Geithner as nominee for Treasury Secretary in November 2008 produced a cumulative abnormal return for financial firms with which he had a prior connection. This return was about 6% after the first full day of trading and about 12% after ten trading days. There were subsequently abnormal negative returns for connected firms when news broke that Geithner’s confirmation might be derailed by tax issues. Personal connections to top executive branch officials can matter greatly even in a country with strong overall institutions, at least during a time of acute financial crisis and heightened policy discretion.

Robert Gordon's The Rise and Fall of American Economic Growth compellingly shows how technical innovation, stimulated by the country's institutions, has radically improved the living standards of the citizens of the US. We conduct an empirical investigation of the impact of the capacity of the US state, as proxied by the presence of post offices, on innovation. We show that there is a strong association between the number of post offices in a county and patenting activity. Our evidence suggests that part of story of US innovation is the capacity and reach of the US state.

We present a model in which firms compete for scarce managerial talent ("alpha") and managers are risk averse. When managers cannot move across firms after being hired, employers learn about their talent, efficiently allocate them to projects, and provide insurance to low-quality managers. When, instead, managers can move across firms, firm-level coinsurance is no longer feasible, but managers may self-insure by switching employer to delay the revelation of their true quality. However, this results in inefficient project assignment, with low-quality managers handling projects that are too risky for them.

This paper identifies the impact of borrowing constraints on homeownership in the U.S. in the aftermath of the 2008 financial crisis. While homeownership declines and tightened credit are evident, the role the tightening of credit has had on the probability of individual households to become homeowners has not been previously identified. The homeownership rate in 2010-2013 is estimated to be 2.3 percentage points lower than if the constraints were set at the 2001 level.
