Jaffe and Palmer (1997) present three distinct variants of the so- called Porter Hypothesis. The “weak” version of the hypothesis posits that environmental regulation will stimulate certain kinds of environmental innovations. The “narrow” version of the hypothesis asserts that flexible...

Cash holdings as a proportion of total assets of U.S. corporations have roughly doubled between 1971 and 2006. Prior research attributes the large cash increase to a rise in firms’ idiosyncratic risk. We investigate two mechanisms by which increased idiosyncratic risk can lead to higher cash...

In this study, we investigate the short run effect of the October 30th, 1995 Quebec referendum on the common stock returns of Quebec firms. Our results show that the uncertainty surrounding the referendum outcome had an impact on stock returns of Quebec firms. We also find that the effect of the...

Using a unique database of 190 newly privatized firms from 36 countries, we investigate the impact of shareholders’ identify on corporate risk-taking behavior. We find strong and robust evidence that state (foreign) ownership is negatively (positively) related to corporate risk-taking....

We characterize a firm as a nexus of activities and projects with their associated cashflow distributions across states of the world and time. With specialized managers intent on maximizing firm value, we show that such a representation leads to a transformation possibility frontier between the...

We generalize the classical expected-utility criterion by weakening transitivity to Suzumura consistency. In the absence of full transitivity, reflexivity and completeness no longer follow as a consequence of the system of axioms employed and a richer class of rankings of probability...

At any given point in time, the collection of assets existing in the economy is observable. Each asset is a function of a set of contingencies. The union taken over all assets of these contingencies is what we call the set of publicly known states. An innovation is a set of states that are not...

We employ the theory of rational choice to examine whether observable choices from feasible sets of prospects can be generated by the optimization of some underlying decision criterion under uncertainty. Rather than focusing on a specific theory of choice, our objective is to formulate a general...

Let 'epsilon' be a class of event. Conditionally Expected Utility decision makers are decision makers whose conditional preferences ≿E, E є 'epsilon', satisfy the axioms of Subjective Expected Utility theory (SEU). We extend the notion of unconditional preference that is conditionally EU to...

The concept of Ambiguity designates those situations where the information available to the decision maker is insufficient to form a probabilistic view of the world. Thus, it has provided the motivation for departing from the Subjective Expected Utility (SEU) paradigm. Yet, the formalization of...
