When quantifying the importance of supply and demand for oil price fluctuations, a wide range of estimates have been reported. Models identified via a sharp upper bound on the short-run price elasticity of supply find supply shocks to be minor drivers. In turn, when replacing the upper bound...

We propose to exploit stochastic volatility for statistical identification of Structural Vector Autoregressive models (SV-SVAR). We discuss full and partial identification of the model and develop efficient EM algorithms for Maximum Likelihood inference. Simulation evidence suggests that the...

We discuss combining sign restrictions with information in external instruments (proxy variables) to identify structural vector autoregressive (SVAR) models. In one setting, we assume the availability of valid external instruments. Sign restrictions may then be used to identify further...

We study shareholder activism through proxy proposals in the United States from 1997-2006. We investigate the determinants for being targeted and the corresponding voting results. By using a distinctive sample that also includes withdrawn and omitted proposals, we circumvent a selection bias...

Does shareholder litigation pay off for investors over long horizons and how much does the type of allegation matter‘ We study whether a disciplining effect occurs for distressed firms and their managers and examine two different groups of allegations. Allegations of violations of duty of...
