We develop an economic theory of “flexibility”, which we interpret as the discretion orability to make a decision that others disagree with. We show that flexibility is essentiallyan option for the decisionmaker, and can be valued as such. The value of the flexibilityoption is decreasing in...

In this paper we analyze an entrepreneur /manager's choice between private and public ownership in a setting in which management needs some "elbow room" or autonomy to optimally manage the firm. In public capital markets, the corporate governance regime in place exposes the firm to exogenous...

In this paper we introduce flexibility as an economic concept and apply it to the firm’s security issuance decision and capital structure choice. Flexibility is the ability to make decisions that one thinks are best even when others disagree. The firm’s management values flexibility because...

Actual portfolios contain fewer stocks than are implied by standard financial analysis that balances the costs of diversification against the benefits in terms of the standard deviation of the returns. Suppose a safety first investor cares about downside risk and recognizes the heavytail feature...

We analyse daily lead-lag patterns in US equity and credit default swap (CDS) returns. We first document that equity returns robustly lead CDS returns. However, we find that the CDS-lag is due to <I>common</I> (and not firm-specific) news and arises predominantly in response to <I>positive</I> (instead of...</i></i>

This discussion paper led to a publication in the <I>Journal of Economic Dynamics and Control</I>. Volume 31(6), pp. 1938-1970.<P> We estimate a dynamic asset pricing model characterized by heterogeneous boundedly rational agents. The fundamental value of the risky asset is publicly available to all...</p></i>

This paper surveys work on dynamic heterogeneous agent models (HAMs) in economics and finance. Emphasis is given to simple models that, at least to some extent, are tractable by analytic methods in combination with computational tools. Most of these models are behavioral models with boundedly...
