We endogenize the market risk (at given technical risk) in firms’ R&D decisions by introducing stochastic R&D in the Hotelling model. It is shown that if the technical risk is sufficiently high, the market risk remains low even if firms pursue similar projects. This leads firms to focus on the...

We model the impact credit constraints and market risk have on the vertical relationships between firms in the supply chain. Firms which might face credit constraints in future investments become endogenously risk averse when accumulating pledgable income. In the short run, the optimal supply...

Economic theory is often abused in practical policy-making. There is frequently excessive focus on sophisticated theory at the expense of elementary theory; too much economic knowledge can sometimes be a dangerous thing. Too little attention is paid to the wider economic context, and to the...

Social preference research has fundamentally changed the way economists think about many important economic and social phenomena. However, the empirical foundation of social preferences is largely based on laboratory experiments with self-selected students as participants. This is potentially...

We develop a dynamic model of investment, cash holdings, financing, and risk management policies in which firms face financing frictions and are subject to permanent and temporary cash flow shocks. In this model, target cash holdings depend on the long-term prospects of the firm, implying that...

This article introduces a method to quantify the effect of a firm’s strategic choices on the risk profile of its profits at different horizons. We combine a demand system for differentiated products with counterfactual paths of risk factors. Prices, costs and quantities respond endogenously to...

The dangers of shouting ``fire'' in a crowded theater are well understood, but the dangers of rushing to the exit in the financial markets are more complex. Yet, the two events share several features, and I analyze why people crowd into theaters and trades, why they run, what determines the...
