Proposed "delinking" legislation would prohibit Pharmacy Benefit Managers (PBMs) from being remunerated based on the rebates and discounts they negotiate for drug insurance plans serving Medicare beneficiaries. This policy would significantly change drug pricing and utilization and shift...

Prices are regulated in many markets, ranging from healthcare to labor to telecommunications. This paper reinterprets the variables in the basic supply-demand model so that both product-definition and quantity are equilibrium outcomes. Specifically, compliance with price controls is achieved by...

I suggest that the aggregate implications of indivisible labor are few, and subtle. First, I model behavior in an 'indivisible labor' environment like those of Diamond and Mirrlees (1978, 1986), Hansen (1985), Rogerson (1988), Christiano and Eichenbaum (1992) and show that aggregate behavior in...

It has long been suggested that trade unions take actions and favor public policies that reduce the quantity of labor so that union members might enjoy greater labor incomes. Can this explain the prevalence of generous public pension programs inducing retirement? I suggest not, by formalizing...

Does Social Security redistribute across cohorts? Or is it a program for purchasing the jobs' of the elderly? I formalize both models, showing how they have some predictions in common the most important of which is that generational accounts have the appearance of a pyramid scheme.' I also...

I show that the indivisible labor' models of Diamond and Mirrlees (1978, 1986), Hansen (1985), Rogerson (1988), Christiano and Eichenbaum (1992), and many others are, when aggregated across persons with the same marginal utility of income, equivalent to the divisible labor model of Lucas and...

Most studies of the intertemporal substitution of work use life cycle data and, from those studies, many have concluded that intertemporal labor substitution is unimportant for macroeconomics. This paper takes another look at life cycle data and argues that a consideration of measurement errors,...

It is argued that changes in workers' budget sets cannot explain the dramatic increases in" civilian work in the U.S. during World War II. Although money wages grew during the period wartime after-tax real wages were lower than either before or after the war. Evidence from the" 1940's also...

The "shutdown" economy of April 2020 is compared to a normally functioning economy both in terms of market and nonmarket activities. Three novel methods and data indicate that the shutdown puts market production 25-28 percent below normal in the short run. At an annual rate, the shutdown is...

Weekly mortality through October 3 is partitioned into normal deaths, COVID, and nonCOVID excess deaths (NCEDs). Before March, the excess is negative for the elderly, likely due to the mild flu season. From March onward, excess deaths are approximately 250,000 of which about 17,000 appear to be...
