William L. Wilkie is Nathe Professor of Marketing, University of Notre Dame (e-mail: [email protected]). How Did This Issue Come About? For much of my career, I have been intrigued with trying to comprehend what the field of marketing is actually about (and what it might be about, what it could be about, what it should be about, and so forth). In recent years, I have joined with my colleague Eliza...

In 1981, Paris and Wilkie [21] indicated it was an open question whether IΣ0 would satisfy the Second Incompleteness Theorem for Herbrand deduction. We will show that IΣ0 will both obey and defy the Herbrandized version of the Second Incompleteness Theorem, depending on which of several equivalent definitions of IΣ0 one examines.

In this paper, we discuss a multiperiod portfolio selection problem with fuzzy returns. We present a new credibilitic multiperiod mean semi- absolute deviation portfolio selection with some real factors including transaction costs, borrowing constraints, entropy constraints, threshold constraints and risk control. In the proposed model, we quantify the investment return and risk associated with...

We examine the effect of introducing credit default swaps (CDSs) on firms’ investment and financing policies. Our model allows for dynamic investment and dynamic financing using equity and debt, and debt holders can trade in the CDS market. After calibrating the model, we compare an economy with a CDS market to an economy without one. The model contains both positive and negative effects of CDS...

Numerous research have been discovered to developed internationalization process model (investment to other country market). Like Johanson and Vahlne, they are among the first to discuss the internationalization process model. There are four key items underlying Johanson and Vahlne’s model, those are market knowledge, market commitment, commitment decision, and current activities. However, many...

This article highlights the importance of investors’downside-risk concerns, and examines optimal investment behaviors in a dynamic downside-risk framework. The authors does not only derive an analytical expression of investors’ optimal behaviors, but also provide economic insights of the properties of the downside risk measure and optimal investment strategies using comparative statics. It shed...

We build a dynamic oligopoly model with endogenous entry in which a particular firm (leader) invests in an innovation process, facing the subsequent entry of other firms (followers). We identify conditions that make it optimal for the leader in the initial oligopoly situation to undertake pre-emptive R&D investment (strategic predation) eventually resulting in the elimination of all followers. ...
