Growth models of the Dutch disease, such as those of Krugman (1987), Matsuyama (1992), Sachs and Warner (1995) and Gylfason et al. (1999), explain why resource abundance may reduce growth. The literature, however, also raises a new question: if the use of resource wealth hurts productivity...

We suggest that overconfidence among policymakers explains why formal decision power over monetary policy is given to committees, while much of the real power to set policy remains with central bank chairmen. Overconfidence implies that the chairman underweights advice from his staff, increasing...

We aim to explain petro populism - the excessive use of oil revenues to buy political support. To reap the full gains of natural resource income politicians need to remain in office over time. Hence, even a purely rent-seeking incumbent who only cares about his own welfare, will want to provide...

We study how monetary policy should respond to shocks which permanently alter the steady state structure of the economy. In such a case monetary policy affects not only the short run misallocations due to nominal rigidities, but also relative prices which stimulate reallocation of capital. We...

This paper investigates the allocation decision of an investor with two projects. Separate managers control the mean return from each project, and the investor may or may not observe the managers' actions. We show that the investor's risk-return trade-off may be radically different from a...

We discuss some difficulties in a dynamic New-Keynesian model with staggered price setting à la Calvo and a convex capital adjustment cost at the firm level, as considered by Woodford (2003, Ch. 5). It is shown that the implied simultaneous price setting and investment decision has not been...

We model capital accumulation in a dynamic New-Keynesian model with staggered price setting à la Calvo. It is assumed that firms do not have access to a rental market for capital. We compare our model with an alternative specification where households accumulate capital and rent it to firms....

According to the Taylor principle a central bank should adjust the nominal interest rate by more than one for one in response to changes in current inflation. Most of the existing literature supports the view that by following this simple recommendation a central bank can avoid being a source of...

Smoothness in aggregate capital accumulation is a necessary condition for New-Keynesian (NK) models to imply a quantitatively relevant monetary transmission mechanism (see, e.g., Woodford 2005). Can that aggregate smoothness be entertained in the context of an NK model featuring lumpy...

What are the consequences for monetary policy design implied by the fact that price setting and investment takes typically place simultaneously at the firm level? To address this question we analyze simple (constrained) optimal interest rate rules in the context of a dynamic New Keynesian model...
