Our model studies the evolution of productivity growth in a competitive industry. The exogenous wage rate determines the firms' engagement in labour productivity enhancing process innovation. There is a unique steady state of the industry dynamics, which is globally stable. In the steady state,...

The run-up in oil prices since 2004 coincided with growing investment in commodity markets and increased price comovement among different commodities. We assess whether speculation in the oil market played a role in driving this salient empirical pattern. We identify oil shocks from a large...

We consider optimal monetary stabilization policy in a New Keynesian model with explicit microfoundations, when the central bank recognizes that private-sector expectations need not be precisely model-consistent, and wishes to choose a policy that will be as good as possible in the case of any...

Instrumental variable estimation requires untestable exclusion restrictions. With policy effects on individual outcomes, there is typically a time interval between the moment the agent realizes that he may be exposed to the policy and the actual exposure or the announcement of the actual...

This paper studies technological change in renewable energies, providing empirical evidence on the determinants of innovative activity with a special emphasis on the role of knowledge spillovers. We investigate two major renewable energy technologies wind and solar across a panel of 21 OECD...

Producing high technology output and supplying sophisticated services often involves costly investment in industry-specific skills. But the threat of poaching means that it is the individual ‘stakeholder’, not the firm, who must bear the cost. We investigate various mechanisms for funding...

Insurance contracts contingent on macroeconomic shocks or on average bank capital could be a way of insuring against systemic crises. With insurance, banks are recapitalized when negative events would otherwise cause a write down of capital or even bank insolvency. In a simple model we...

We construct a price-theoretic model of firms' integration decisions under perfect competition and study their interplay with consumer demand and welfare. Integration is costly to implement but is effective at coordinating production decisions. The price of output influences the ownership...

This paper studies the question to what extent premia for macroeconomic risks in banking are sufficient to avoid banking crises. We investigate a competitive banking system embedded in an overlapping generation model subject to repeated macroeconomic shocks. We show that even if banks fully...
