How capital taxes harm economic growth: Britain versus the United States

The different methods used by Great Britain and the United States to finance World War II had a significant impact on postwar economic growth in the two countries. In this article, Lee Ohanian discusses the evolution of war-finance policies in the two countries and examines how the different approaches—taxing capital income versus issuing government debt—led to differences in economic performance after the war.Great Britain ; Income tax ; War - Economic aspects

Back to the future with Keynes

This article analyzes Keynes's "Economic Possibilities for our Grandchildren"- an essay presenting Keynes's views about economic growth into the 21st century - from the perspective of modern growth theory. I find that the implicit theoretical framework used by Keynes to form his expectations about the 21st-century world economy is remarkably close to modern growth models, featuring a stable steady-state growth path driven by technological progress. On the other hand, Keynes's forecast of employment in the 21st century is far off the mark, reflecting a mistaken view that the income elasticity of leisure is much higher than that of consumption.Economic history ; National income

Are Phillips curves useful for forecasting inflation?

This study evaluates the conventional wisdom that modern Phillips curve-based models are useful tools for forecasting inflation. These models are based on the non-accelerating inflation rate of unemployment (the NAIRU). The study compares the accuracy, over the last 15 years, of three sets of inflation forecasts from NAIRU models to the naive forecast that at any date inflation will be the same over the next year as it has been over the last year. The conventional wisdom is wrong; none of the NAIRU forecasts is more accurate than the naive forecast. The likelihood of accurately predicting a change in the inflation rate from these three forecasts is no better than the likelihood of accurately predicting a change based on a coin flip. The forecasts include those from a textbook NAIRU model, those from two models similar to Stock and Watson's, and those produced by the Federal Reserve Board.Inflation (Finance) ; Forecasting ; Phillips curve

New Deal policies and the persistence of the Great Depression: a general equilibrium analysis

There are two striking aspects of the recovery from the Great Depression in the United States: the recovery was very weak and real wages in several sectors rose significantly above trend. These data contrast sharply with neoclassical theory, which predicts a strong recovery with low real wages. We evaluate the contribution of New Deal cartelization policies designed to limit competition and increase labor bargaining power to the persistence of the Depression. We develop a model of the bargaining process between labor and firms that occurred with these policies, and embed that model within a multi-sector dynamic general equilibrium model. We find that New Deal cartelization policies are an important factor in accounting for the post-1933 Depression. We also find that the key depressing element of New Deal policies was not collusion per se, but rather the link between paying high wages and collusion.Depressions

Does Neoclassical Theory Account for the Effects of Big Fiscal Shocks? Evidence From World War II

There is much debate about the usefulness of the neoclassical growth model for assessing the macro-economic impact of fiscal shocks. We test the theory using data from World War II, which is by far the largest fiscal shock in the history of the United States. We take observed changes in fiscal policy during the war as inputs into a parameterized, dynamic general equilibrium model and compare the values of all variables in the model to the actual values of these variables in the data. Our main finding is that the theory quantitatively accounts for macroeconomic activity during this big fiscal shock.

The demand for money and the nonneutrality of money

Many economists have worried about changes in the demand for money, since money demand shocks can affect output variability and have implications for monetary policy. This paper studies the theoretical implications of changes in money demand for the nonneutrality of money in the limited participation (liquidity) model and the predetermined (sticky) price model. In the liquidity model, we find that an important connection exists between the nonneutrality of money and the relative money demands of households and firms. This model predicts that the real effect of a money shock rose by 100 percent between 1952 and 1980, and subsequently declined 65 percent. In contrast, we find that the nonneutrality of money in the sticky price model is invariant to changes in money demands or other monetary factors. Several researchers have concluded from VAR analyses that the effects of money shock over time are roughly stable. This view is consistent with the predictions of the sticky price model, but is harder to reconcile with the specific pattern of time variation predicted by the liquidity model.Money
