12 NEW Marginal Revolution University Videos in Achieve accompanied by assessment questions.

Are free goods good? Surprisingly, the answer is "Not necessarily." In the chapter on Taxes and Subsidies, We contrast two strategies for making a good "free": 1) outlawing the sale of a good for money, i.e., mandating a zero-price ceiling, and 2) subsidizing production to such an extent that prices plummet to zero. In the first scenario, deadweight loss arises as society forfeits the value of transactions that never occur. In the second, deadweight loss results from excessive transactions where the marginal cost exceeds the marginal value.

The Great Depression is over: Modern Principles focuses on the Great Financial Crisis and the Pandemic Recession, exemplifying the core of macroeconomics and policy. These events showcase a demand-driven recession followed by a supply-driven one, well-illustrated by our dynamic AD-AS model. Focusing on these recessions also moves the lessons beyond the shifting of curves and towards important discussions of shadow banking, securitization, the microeconomics of externalities, and how monetary and fiscal policy must change when the goal – as during a pandemic -- is not to get people back to work!

The new tools of the Federal Reserve: In the sixth edition, the authors emphasize that although the Federal Reserves ultimate power is the power to create money, its daily influence on aggregate demand is accomplished through the payment of interest on reserves held at the Fed. Open market operations are still relevant for discussions on quantitative easing and repurchase agreements, but the primary focus is on understanding how the Fed affects aggregate demand by adjusting interest on reserves.
