We estimate how an acquiring firm's risk changes depending on whether the market initially judges the acquisition to be neutral, strongly negative, or strongly positive for the shareholders of the acquiring firm. We found that for an average neutral acquisition, the annualized standard deviation...

The Cox, Ross, and Rubinstein binomial model is generalized to the multinomial case. Limits are investigated and shown to yield the Black-Scholes formula in the case of continuous sample paths for a wide variety of complete market structures. In the discontinuous case a Merton-type formula is...

This paper provides a behavioral analysis of BP, whose capital budgeting decisions in the last decade have resulted in a series of high profile accidents, including the worst environmental disaster in U.S. history. The analysis uses BP as a vehicle to discuss the application of business...

The paper makes four contributions. First, it provides new data and findings about credit card usage segmentation in respect to spending and borrowing behavior. Second, it sets the new findings against the backdrop of the newly emerging literature on financial literacy. There is great...

Risk managers operate in the space of risk and returns, constrained by financial market regulations. How can risk managers assess risk associated with changing regulatory structures, given that theories about the relationship between risk and return are much more developed than theories about...

We discuss here the implications that arise for the fundamental duality relationships given by Roy's Identity (1943) and Shephard's Lemma (1953) when the underlying consumer choice problem is dynamic and involves uncertainty

An individual demand function is said to satisfy the finite basis property when its set of Engel curves has a finite spanning subset. In the present letter we discuss why this property underlies the theory of exact aggregation

This letter explores the robustness (in an approximating sense) of a class of demand systems which have been discussed by Gorman. This class is of fundamental interest because it is known to be the only class of demand systems which permits exact aggregation. We discuss the reasons which...

This letter explores some global properties of the Gorman class of demand functions. We find that generalizing the homothetic preferences case to non-homotheticity gives rise to an unexpected global problem. In particular, interaction of the bounded budget share condition with either Slutsky...
