A Robust Optimization Approach to Capital Rationing and Capital Budgeting

We study the pure capital rationing and the horizon capital budgeting problems using a robust optimization framework. The models and the methodology we propose take into account the uncertainty of the input data. The uncertainty of the cash flows is modeled as a range of values that is allowed for each uncertain data. Unlike stochastic models, this approach does not make assumptions on the probability distribution of uncertain data. Moreover, this approach is highly tractable, easy to implement, and provides insights into portfolio selection problems. An attractive point of the model is that the decision maker can set the value of the parameters that control the robustness of the optimal solution, in order to balance the trade-off between protection level and performance. We illustrate our models with examples that show promising results. We also provide new duality and KKT optimality conditions.     

OPERATING SYSTEM PRICES IN THE HOME PC MARKET*

Because the demand for OS is a derived demand revealed through the demand for PCs and because its elasticity is relatively small, the profit‐maximizing price of DOS/WIN that would result from a static equilibrium is much higher than the observed price. We investigate this assertion empirically by fitting a differentiated‐products model of the home PC market to panel data of all PC brands sold in the G7 countries over the period 1995–1999. The results confirm that the low value of the aggregate elasticity of demand for PCs is the result of differentiation and substitution among PCs.     

A survey of market orientation research (1995-2008)

Since 1990, market orientation (MO) has received considerable attention in the marketing literature. Little research so far provides preliminary and useful information to facilitate good understanding of MO. This study presents a comprehensive survey of extant marketing literature using keyword classification from 1995 to 2008. It serves as a tutorial and aims to help the beginner researcher or practitioner to have access to MO, including its definitions, applications and problem domains. Based on the scope of 514 MO articles, we find that the number of publications on MO has significantly increased since 2001 with steady growth in recent years. In addition, these selected articles are scattered across 153 journals and mostly published in 10 academic journals. The contribution of our paper is to provide a means (i.e., keyword index) to conceptualize and operationalize the coverage of MO. It provides a conceptual framework to organize this vast body of research. This study ends with some discussions and conclusions.     

Proposal for two model undergraduate curricula in entrepreneurship

This paper takes three important preliminary steps towards the development of undergraduate curricula in entrepreneurship. First, it provides one of the first analyses comparing the entrepreneurship education standards proposed by the Consortium for Entrepreneurship Education and the European Commission’s Education and Training in Entrepreneurship initiative. Next, it presents an analysis of results of a workshop of entrepreneurship educators regarding development of an undergraduate entrepreneurship standard for business schools. With these two elements in place, the paper makes recommendations for model undergraduate entrepreneurship curricula for majors and concentrations, and concludes with a discussion of the issues in developing and implementing model curricula in a manner consistent with emerging standards in US business schools.     

Predicting the unpredictable: The impact of meterological satellites on weather forecasting

The practice of weather forecasting was revolutionized with the launching of the first meterological satellite in April, 1960. This paper examines the impact of this new form of weather observation on the accuracy of weather forecasts. In studying this question, the author also discusses the influence of numerical weather prediction on forecasting accuracy. Estimates of the economic saving associated with improved weather forecasts are provided. The author concludes that weather satellites have greatly improved the accuracy of storm warning forecasts. It is unlikely, however, that the contribution of technological advances, such as meteorological satellites and numerical weather prediction, will be fully exploited, until systems for disseminating and using weather information are substantially improved.     

Export diversification in a transitioning economy

How does the process of export diversification take place in an economy in transition, especially in light of government policy aimed at trade liberalization? This article examines this question by considering a directed policy effort by Syria – an economy in transition from both economic centralization and resource dependence – to liberalize its trade between 2001 and 2008. In addition to documenting the patterns of diversification at the aggregate level since the implementation of the policy, we also examine factors that are related to diversification at the sectoral level. Our findings suggest that, while Syria has achieved reasonably rapid export diversification, this may to a large extent be the result of structural transformations in the economy, and that further diversification may require continued policy reform designed to strengthen Syria's weak institutional and business environment.
