As we approach the tenth anniversary of the passage of the Affordable Care Act, it is important to reflect on what has been learned about the impacts of this major reform. In this paper, we review the literature on the impacts of the ACA on patients, providers, and the economy. We find strong evidence that the ACA's provisions have increased…

This paper investigates to what extent socioeconomic status (SES)-based affirmative action in college admissions can produce racial diversity. Using simulation models, we investigate the racial and socioeconomic distribution of students among colleges under the use of race- or SES-based affirmative action policies, or targeted, race-based…

This paper assesses the impact of welfare reform's parental work requirements on low-income children's cognitive and social-emotional development. The identification strategy exploits an important feature of the work requirement rules--namely, age-of-youngest-child exemptions--as a source of quasi-experimental variation in first-year maternal…

With increasing frequency, U.S. presidents have orchestrated relations between federal and state governments. A defining feature of this "executive federalism" is a pragmatic willingness to both borrow from and reconstitute very different types of past federalisms. A case in point is President Barack Obama's Race to the Top (RttT)…

Policy analyses frequently clash. Their disagreements stem from many sources, including models, empirical estimates, and values such as who should have standing and how different criteria should be weighted. We provide a simple taxonomy of disagreement, identifying distinct categories within both the positive and values domains of normative policy…

Teacher pension systems concentrate retirements within a narrow range of the career cycle by penalizing individuals who separate too soon or remain employed too long. The penalties result in the retention of some teachers who would otherwise choose to leave, and the premature exit of some teachers who would otherwise choose to stay. We examine the…

In this paper, we consider several features of teacher-retention policies based on value-added measures of effectiveness under a variety of empirically grounded rules and parameters. We consider the effects of policy design by varying the standard above which satisfactory teachers are expected to perform. We simulate recently adopted policies that…

All of the authors seem to share the perception that one can no longer expect much from macroeconomic policies. The authors of this paper share this opinion, but this should not be interpreted as the skeptical view that macroeconomic policies are ineffective on employment. They saw from the Korea's two crises how contrasting outcomes could result…

This paper employs panel estimators with data on the 50 American states for the years 1963 to 2006 to test the relationship between Unemployment Insurance (UI) trust fund solvency and UI benefit generosity. We find that both average and maximum weekly UI benefit amounts, as ratios to the average weekly wage, are higher in states and in years with…

Since the 1990s many OECD countries have adopted fiscal rules. After the adoption of these rules, the ratio of social transfers to government consumption substantially declined, and it recovered following the global economic crisis. Using a sample of 22 OECD countries, we found a negative effect of fiscal rules on the ratio of social transfers to…

The prisoner's dilemma and stag hunt games, as well as the apparent benefits of collaboration, have motivated governments to promote more frequent and effective collaboration through a variety of policy approaches. Sometimes, multiple kinds of policies are applied concurrently, and yet little is understood about how these policies might interact…

Comparing the papers on the Korean and the U.S. situations leads to interesting conclusions. Cho and Shin argue that the recent crisis did not create huge problems in the labor market because Korea was firstly in a fundamentally sound economic situation and secondly took adequate anti-crisis measures, in particular by stabilizing internal demand.…

This paper estimates risk reductions for each layer of security designed to prevent commercial passenger airliners from being commandeered by terrorists, kept under control for some time, and then crashed into specific targets. Probabilistic methods are used to characterize the uncertainty of rates of deterrence, detection, and disruption, as well…

Slow economic growth since the end of the U.S. recession in June of 2009 has not yet translated into increases in employment large enough to meaningfully reduce the rate of unemployment. Because expansionary macroeconomic policy has been pursued on both the fiscal and monetary fronts, it appears at first glance that the hands of government at this…

Governments across the world are investing large amounts of money in scientific research, often with the belief that such investments will increase economic growth--yet the scientific evidence for this belief is, as Colin Macilwain notes, "patchy." Science agencies are charged with identifying and funding the best science, yet there is little…
