Public authorities often invoke the precautionary principle to ban or postpone the development of innovative projects with uncertain but potentially harmful irreversible impacts on the environment or health. As stated in the Rio declaration, the precautionary principle suggests balancing costs...

We investigate subjective reactions when subjects realize they have been victims of framing-effects in situations of risky choices - that is, when they violated the invariance principle in decision-theory. We try to assess various explanations of this violation in terms of bounded rationality...

This paper brings into focus a link between the investment and financing decisions of a firm which has an access to costly debt financing. Our analysis shows that lump-sum debt issuance costs play a prominent role in a determination of the optimal investment strategy. Faced with larger lump-sum...

We characterize sequential (preemption) and simultaneous (coordination) equilibria, as well as joint-value maximizing (cooperation) solutions, in a model of investment timing allowing for externalities in both flow pro...ts and investment costs. For two ex-ante symmetric ...rms, either...

In a real option model, we show that the standard analysis of vertical relationships transposes directly to investment timing. Thus, when a firm undertaking a project requires an outside supplier (e.g., an equipment manufacturer) to provide it with a discrete input to serve a growing but...

This note further characterizes the tacit collusion equilibria in the investment timing game of Boyer, Lasserre and Moreaux [1]. Tacit collusion equilibria may or may not exist, and when they do may involve either finite time investments (type 1) or infinite delay (type 2). The relationship...

In this paper we examine the applicability of arbitrage theory to real estate. Arbitrage theory has been applied to the valuation of mortgages using partial differential equations, however the implicit assumptions made are problematic when applied to real estate. The latter is a very complex...

Real options models characterized by the presence of ambiguity have been recently proposed. But based on recursive multiple-priors approaches to solve ambiguity, these seminal models reduce individual preferences to extreme pessimism by considering only the worst case scenario. In contrast, by...
