Standard consumption models assume a notional consumption flow that does not distinguish between nondurable and durable consumption. Such notional-consumption models generate notional marginal propensities to consume (MPC). By contrast, empirical work and policy discussions often highlight...

This lecture focuses on the costs of public debt when safe interest rates are low. I develop four arguments.First, I show that the current U.S. situation in which safe interest rates are expected to remain below growth rates for a long time, is more the historical norm than the exception. If the...

I study unemployment insurance (UI) in general equilibrium with incomplete markets, search frictions, and nominal rigidities. An increase in generosity raises the aggregate demand for consumption if the unemployed have a higher marginal propensity to consume (MPC) than the employed or if agents...

Dispersion in marginal revenue products of inputs across plants is commonly thought to reflect misallocation, i.e., dispersion is "bad." We document that most dispersion occurs across plants within rather than between firms. In a model of multi-plant firms, we then show that dispersion can be...

First, I show that the current U.S. situation in which safe interest rates are expected to remain below growth rates for a long time, is more the historical norm than the exception. If the future is like the past, this implies that debt rollovers, that is the issuance of debt without a later...

Blanchard develops four main arguments concerning the costs of public debt when safe interest rates are low.First, the current US situation in which safe interest rates are expected to remain below growth rates for a long time is more the historical norm than the exception. If the future is like...

This note proposes a growth model that is derived from the standard Solow growth model by replacing the neoclassical production function with Kaldor's technical progress function while maintaining a marginalist theory of factor prices in the spirit suggested by von Weizsäcker (1966, 1966b). The...

In Abhandlungen von Dorfman und Samuelson 1986 und van Suntum 1988 wird Thünen's berühmte Grabsteinformel unter Berücksichtigung seiner spezifischen Annahmen bestätigt. Allerdings wird Thüenen's Vorgehen zur Erzielung dieses Ergebnisses bis heute kontrovers diskutiert. Mit diesem Papier...

We address the long standing question of whether production factors are paid their marginalproducts. We propose a new approach that circumvents the need to specify productionfunctions and to compare marginal products to factor payments. Our approach is based on asimple equation that directly...
