Can government policies that reduce the natural level of output increase actual output? In other words, can policies that are contractionary according to the neoclassical model, be expansionary once the model is extended to include nominal frictions? For example, can facilitating monopoly pricing of firms and/or increasing the bargaining power of workers' unions increase output? Most economists would find the mere question absurd. This article, however, shows that the answer is yes under the special "emergency" conditions that apply when the short-term nominal interest rate is zero and there is excessive deflation. Furthermore, it argues that these special "emergency" conditions were satisfied during the Great Depression in the United States.This result indicates that the National Industrial Recovery Act (NIRA), a New Deal policy universally derided by economists ranging from Keynes (1933) to Friedman and Schwartz (1963) and all the way to the modern literature, increased output in 1933 when Franklin Delano Roosevelt (FDR) became the president of the United States. The NIRA declared a temporary "emergency" that suspended antitrust laws and facilitated union militancy to increase prices and wages. The stated goal of these emergency actions was to battle the downward spiral of wages and prices observed in the 1929-1933 period. This article studies the NIRA in a dynamic stochastic general equilibrium (DSGE) model with staggered price setting. The NIRA creates distortions that move the natural level of output away from the efficient level by temporarily increasing the monopoly power of firms and workers. This is expansionary due to an expectations channel. Demand depends on the path for current and expected short-term real interest rates and expected future income. The real interest rate, in turn, is the difference between the short-term nominal interest rate and expected inflation. The NIRA increases inflation expectations because it helps workers and firms to increase prices and wages, and thus reduces, or even eliminates, deflation. Higher inflation expectations decrease real interest rates and thereby stimulate demand. Expectations of similar policy in the future increase demand further by increasing expectations about future income.Under regular circumstances, these policies are counterproductive. A central bank that targets price stability, for example, will offset any inflationary pressure
