Real business-cycle theory: rather harmful

Followers of the real business-cycle theory believe that the New Deal caused the depression to persist longer than it would otherwise have. Harold L. Cole and Lee E. Ohanian say Roosevelt's policies prolonged the depression by seven years. According to their study, the "New Deal labor and industrial policies did not lift the economy out of the Depression", but that the "New Deal policies are an important contributing factor to the persistence of the Great Depression". They claim that the New Deal "cartelization policies are a key factor behind the weak recovery". They say that the "abandonment of these policies coincided with the strong economic recovery of the 1940s". The study by Cole and Ohanian is based on a real business-cycle theory model. Laurence Seidman noted that according to the assumptions of Cole and Ohanian, the labor market clears instantaneously, which leads to the incredible conclusion that the surge in unemployment between 1929 and 1932 (before the New Deal) was in their opinion both optimal and solely based on voluntary unemployment. Additionally, Cole and Ohanian's argument does not count workers employed through New Deal programs. Such programs built or renovated 2,500 hospitals, 45,000 schools, 13,000 parks and playgrounds, 7,800 bridges, 700,000 miles (1,100,000 km) of roads, 1,000 airfields and employed 50,000 teachers through programs that rebuilt the country's entire rural school system.
