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...

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...

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...

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...

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...

We examine the optimal allocation of equity and debt across banks and industrial firms when both are faced with incentive problems and firms borrow from banks. Increasing bank equity mitigates the bank-level moral hazard but may exacerbate the firm-level moral hazard due to the dilution of firm...

In a standard financial market model with asymmetric information with a finite number N of risk-averse informed traders, competitive rational expectations equilibria provide a good approximation to strategic equilibria as long as N is not too small: equilibrium prices in each situation converge...

We examine the relation between optimal venture capital contracts and the supply and demand for venture capital. Both the composition and type of financial claims held by the venture capitalist and entrepreneur depend on the market structure. Moreover, different market structures involve...
