We study a continuous-time principal-agent model in which a risk-neutral agent with limited liability must exert unobservable effort to reduce the likelihood of large but relatively infrequent losses. Firm size can be decreased at no cost or increased subject to adjustment costs. In the optimal...

We analyse the demand for hedging and insurance by a firm that faces liquidity risk. The firm's optimal liquidity management policy consists of accumulating reserves up to a threshold and distributing dividends to its shareholders whenever its reserves exceed this threshold. We study how this...

In this paper, we investigate the optimal timing and location for deep geological disposal of nuclear waste. Our model is based on the real options approach to investment under uncertainty. In this context, the problem is similar to the optimal exercise policy for a perpetual American spread option.

This paper proposes a dynamic model of financial markets where some investors are prone to the confirmation bias. Following insights from the psychological literature, these agents are assumed to amplify signals that are consistent with their prior views. In a model with public information only,...
