We consider a simple model of energy saving investments under uncertainty of energy costs. Adjustment delays in replacing energy-intensive capital follow from two natural elements: uncertainty and heterogeneity of the existing capital structure. They imply a simple dichotomy where short-run output contracts, but the long-run output recovers and increases above the initial output, despite the in...

We examine the effect of financial integration on capital stocks and income per capita, explicitly taking into account the division of output between tradable and non-tradable goods. Capital per worker in a financially integrated country is shown to depend on the size and relative capital-intensity of the tradable sector. Using a panel of 67 countries over the period 1976-1999, we show a weakly...

We document that at business cycle frequency, nominal variables, such as aggregate price levels and nominal interest rates, are more correlated across countries than real output. Since national central banks control the domestic money supply and their objective has been to keep the nominal environment stable this might seem puzzling. We ask whether a simple, transparent standard international b...

This paper examines how output prices and markups vary across the size distribution of producers. It uses unique plant-level data on physical output, revenue, and input expenditures for six homogeneous U.S. manufactured products. The results reveal that, for five of the six products, output prices decline systematically with increases in plant size. In the most extreme case, corrugated boxes, t...

Yes, it makes a lot of sense. Using the Smets and Wouters (2007) model of the U.S. economy, we find that the role of the output gap should be equal to or even more important than that of annualized inflation when designing a simple loss function to represent household welfare. The high weight on the output gap is driven by several important characteristics in the estimated model, including a lo...

This research examines results from laboratory experiments in which five human subjects participate as sellers in a Cournot oligopoly environment. The central issue is whether repeated play among a group of privately informed subjects will lead to convergence to a unique, static, noncooperative Nash equilibrium. The experiments were designed so that the implications of different hypotheses abou...

abstract the purpose of this paper is to test the hypothesis first proposed by romer (1993); suggesting that inflation is lower in more open economies. according to this hypothesis, central banks have a lower incentive to engineer surprise inflations in more-open economies because the phillips curve is steeper. furthermore, comparing with other empirical studies, this paper has used the new kof...

A basic neoclassical model of production is often used to assess the contribution of investment to output growth. In the model, investment raises the capital stock and output growth increases in proportion to the growth in capital. It has been argued, however, that computers, as a “general purpose technology,” lead to process innovations and facilitate organizational coinvestments. Since there ...
