Market Power in Neoclassical Growth Models

Click here to read my most recent paper, coauthored with Larry Ball. Here is the abstract:

This paper examines the optimal accumulation of capital and the effects of government debt in neoclassical growth models in which firms have market power and therefore charge prices above marginal cost. In this environment, the real interest rate earned by savers is less than the net marginal product of capital. We establish a new method for evaluating dynamic efficiency that can be applied in such economies. A plausible calibration suggests that the wedge between the real interest rate and the marginal product of capital is more than 4 percentage points and that the U.S. economy is dynamically efficient. In addition, government Ponzi schemes can have different implications for welfare than they do under competition. Even if the government can sustain a perpetual rollover of debt and accumulating interest, the policy may nonetheless reduce welfare by depressing steady-state capital and aggregate consumption. These findings suggest that even with low interest rates, as have been observed recently, fiscal policymakers should still be concerned about the crowding-out effects of government debt.

CBO on the Minimum Wage

NPR reports:

Raising the federal minimum wage to $15 an hour by 2025 would increase wages for at least 17 million people, but also put 1.4 million Americans out of work, according to a study by the Congressional Budget Office released on Monday.

A phase-in of a $15 minimum wage would also lift some 900,000 out of poverty, according to the nonpartisan CBO. This higher federal minimum could raise wages for an additional 10 million workers who would otherwise make sightly above that wage rate, the study found.

Potential job losses were estimated to affect 0.9 percent of workers, the CBO wrote, adding: "Young, less educated people would account for a disproportionate share of those reductions in employment."

Sebastian Mallaby was a good column on the GameStop phenomenon.

A family member also suggested a good hypothesis: The bubble is being being driven by internet trolls. The right model of a troll is a person willing to waste his time and money to get other people to waste their time and money.

Should the stimulus checks be raised from $600 to $2000?

Larry Summers makes a good case that, on this issue, Mitch McConnell is right, and Donald Trump, Nancy Pelosi, and Chuck Schumer are wrong.
