This paper argues that a linear statistical model with homoskedastic errors cannot capture the nineteenth-century notion of a recurring cyclical pattern in key economic aggregates. A simple nonlinear alternative is proposed and used to illustrate that the dynamic behavior of unemployment seems...

It has long been argued that cyclical fluctuations in labor and capital utilization and the presence of overhead labor and capital are important for explaining procyclical productivity. Here I present two simple and direct tests of these hypotheses, and a way of measuring the relative importance...

The marginal cost of plant capacity, measured by the price of equity is significantly procyclical. Yet, the price of a major intermediate input into expanding plant capacity, investment goods, is coutercyclical. The ratio of these prices is Tobin's q. We interpret the fact that Tobin's q differs...

This paper argues that analysis of seasonal fluctuations can shed light on the nature of business cycle fluctuations. The fundamental reason is that in many instances identifying restrictions about seasonal fluctuations are more believable than analogous restrictions about non-seasonal...

This paper explores the behavior of the U.S. economy during the interwar period from the perspective of a model in which the existence of non-convexities in the intermediation process gives rise to a multiplicity of equilibria. The resulting indeterminancy is resolved through a sunspot process...

This paper presents an aggregate demand-driven model of business cycles that provides a new explanation for the procyclicality of productivity, and simultaneously predicts large welfare losses from monetary non-neutrality. The key features of the model are an input- output production structure,...

Each of the main explanations of procyclical labor productivity, or short-run increasing returns to labor (SRIRL), is closely associated with a competing theory of the business cycle: Real business cycle theorists attribute SRIRL to procyclical technological shocks, proponents of recent theories...

We document that the nature of business cycles evolves over the process of development and structural change. In countries with large declining agricultural sectors, aggregate employment is uncorrelated with GDP. During booms, employment in agriculture declines while labor productivity increases...
