THE EFFECT OF TECHNOLOGICAL IMPROVEMENT ON CAPACITY EXPANSION FOR UNCERTAIN EXPONENTIAL DEMAND WITH LEAD TIMES

We formulate a model of capacity expansion that is relevant to a service provider for whom the cost of capacity shortages would be considerable but difficult to quantify exactly. Due to demand uncertainty and a lead time for adding capacity, not all shortages are avoidable. In addition, technological innovations will reduce the cost of adding capacity but may not be completely predictable. Analytical expressions for the infinite horizon expansion cost and shortages are optimized numerically. Sensitivity analyses allow us to determine the impact of technological change on the optimal timing and sizes of capacity expansions to account for economies of scale, the time value of money and penalties for insufficient capacity.     

Regulations for the Eighth International Congress of Actuaries

Abstract

The present paper proposes and investigates a procedure for numerical evaluation of the transition probabilities for a time-inhomogeneous Markov process when the intensities are known (estimated). The procedure is based on Taylor-expansion of the transition probabilities linked with the Chapman-Kolmogorov equations.     

Simulating Price-Taking

In this article, the author presents a price-takers’ market simulation geared toward principles-level students. This simulation demonstrates that price-taking behavior is a natural result of the conditions that create perfect competition. In trials, there is a significant degree of price convergence in just three or four rounds. Students find this simulation to be a fun, educational experience that adds value to their understanding of competitive markets.     

What Plato Knew About Enron

This paper applies Plato’s cave allegory to Enron’s success and downfall. Plato’s famous tale of cave dwellers illustrates the different levels of truth and understanding. These levels include images, the sources of images, and the ultimate reality behind both. The paper first describes these levels of perception as they apply to Plato’s cave dwellers and then provides a brief history of the rise of Enron. Then we apply Plato’s levels of understanding to Enron, showing how the company created its image and presented information to support that image, and how the public eventually emerged from the cave to realize the truth about Enron’s actual accounting practices and financial state, which led to the corporation’s downfall. We find Plato’s allegory both useful in analyzing the relationship between Enron and the public and instructive about the power and moral responsibility of Enron’s executives.     

Let them talk! Managing primary and extended online brand communities for success

It is clear that customer-to-customer contact through informal social networking and more formal company-sponsored platforms, such as discussion forums, is an increasingly integral element in building brand communities. There are many benefits to this interaction, such as nurturing brand champions and ‘super users,’ and reduced service costs through customer-to-customer solutions for product problems. However, there are also hazards inherent in these largely unregulated communities, such as the potential damage of widely spread negative information, which may be based on fact or on malicious intent. Herein, we summarize the results of several years of research examining these communities in an attempt to understand why they succeed, what benefits can be extracted from them, and—in particular—how negative information emerging in these environments can be strategically managed. Based on a series of quantitative and qualitative studies, we identified several key drivers of online brand community success (i.e., intervention, conversion, value creation, and harvesting) and the different combinations of community players who must collaborate to achieve such success. Delving more deeply into the issue of negative information management, we find that the topic being discussed (i.e., core versus augmented product) and the validity of the claim greatly influence a firm's appropriate strategic response. Throughout this article, we offer managerial guidance on the most effective ways to develop primary brand communities that encourage loyalty, purchases, and positive word of mouth.     

The impact of electronic commerce on small and midsized spanish companies

Electronic commerce (EC) is not new for some European Union countries, but in others, such as Spain, it is only at the developmental stage. Now that Spain has joined the third phase of the economic and monetary union, Spanish companies' internationalization and the progressive change in the Spanish consumers' buying habits are determining the search for new business strategies. Starting with an analysis of the Spanish business environment, followed by an internal scanning of small and midsized Spanish companies, this paper will analyze the viability of EC as a new business strategy.     

Earnings management and accrual anomaly across market states and business cycles

This paper examines if the conditioning on market states is important to earnings management behaviors and profitability of accrual hedge strategy. This paper discusses four findings. First, accrual profits are consistently positive across both market states and significantly higher in DOWN markets. Second, while earnings management exists in both market states, the management effort is less effective and short-lived in the DOWN state. Third, this paper finds that the accrual effect exists but varies across industries. Finally, this paper examines how business cycles associate with accrual anomaly and show that accruals mispricing cannot be fully captured by macroeconomic model predicted returns.
