Fiscal policy in the U.S. and other countries renders intertemporal budgets non-differentiable, nonconvex, and discontinuous. Consequently, assessing work and saving responses to policy requires global optimization. This paper develops the Global Life-Cycle Optimizer (GLO), a stochastic...

Physicians commonly receive marketing-related transfers from drug firms. We examine the impact of these relationships on the prescribing of physician-administered cancer drugs in Medicare. We find that prescribing of the associated drug increases 4\% in the twelve months after a payment is...

Across many studies subjective well-being follows a U-shape in age, declining until people reach middle-age, only to rebound subsequently. Ill-being follows a mirror-imaged hump-shape. But this empirical regularity has been replaced by a monotonic decrease in illbeing by age. The reason for the...

This paper examines the scalability of the results from the Tennessee Student-Teacher Achievement Ratio (STAR) Project, a prominent educational experiment. We explore how the misalignment between the experimental design and the econometric model affects researchers' ability to learn about the...

Mobile app commissions paid by app developers to a monopolist device maker/app store operator are examined. Three results are demonstrated. First, unregulated app commissions are set at a level that maximises consumer surplus. Second, eliminating app commissions will lead to higher device...

This study investigates the growing wage disparity between older and younger workers in high-income countries. We propose a conceptual framework of the labor market in which firms cannot change the contracts of older employees and cannot freely add higher-ranked positions to their organizations....

We examine banking regulation in a macroeconomic model of bank runs. We construct a general equilibrium model where banks may default because of fundamental or self-fulfilling runs. With only fundamental defaults, we show that the competitive equilibrium is constrained efficient. However, when...

Recent social movements stand out by their spontaneous nature and lack of stable leadership, raising doubts on their ability to generate political change. This article provides systematic evidence on the effects of protests on public opinion and political attitudes. Drawing on a database...

While reliance on human discretion is a pervasive feature of institutional design, human discretion can also introduce costly noise (Kahneman, Sibony, and Sunstein 2021). We evaluate the consequences, determinants, and trade-offs associated with discretion in high-stake decisions assessing bank...

During the Progressive Era (1900-29), economic growth was rapid but volatile. Boom and busts witnessed the formation and failure of tens of thousands of firms and thousands of banks. This essay uses new data and methods to identify causal links between failures of banks and bankruptcies of...
