Price competition in the market for business telecommunications services

We estimate a two-step control-function model that relates incumbent prices for small-business telecommunications services to the number of facilities-based entrants, cost, demand, regulatory conditions, and a correction for endogenous market structure. Results show that the price effects from entry are understated in ordinary least squares regressions. When controlling for endogeneity, prices are negatively related to the number of entrants, indicating that markets without a competitive presence could exhibit market power. These findings should prove helpful to the Federal Communications Commission and other State regulators determining the conditions under which price and other forms of regulation may be relaxed.     

Knowledge management in technology-focused firms in emerging economies: Caveats on capabilities,networks, and real options

In mature economies, technology-focused industries and the management of knowledge are widely viewed as critical to success. Increasingly, in emerging economies technology-focused industries and the management of knowledge are also viewed as important. To date, however, little is known about such activities in emerging economies. Particularly, it is not understood how knowledge management can impact efforts for corporate renewal in such environments. The literatures of the resource-based view of the firm, social capital/network theory, and real options theory are vital to providing insights for technology-focused industries and the management of knowledge in mature economies. In this paper we focus on the caveats when applying such theoretical foundations to emerging economies. To illustrate these issues we will draw on the largest emergent economy in the world, China.

Bidding asymmetries in multi-unit auctions: Implications of bid function equilibria in the British spot market for electricity

This paper introduces and tests Bid Function Equilibria (BFE) in the British spot market for electricity. BFE extend von der Fehr and Harbord's (1993) multi-unit auction model of wholesale electricity markets by allowing firms to have heterogeneous costs for different generating units. Pure-strategy equilibria in BFE predict asymmetric bidding by producers: a single firm (the “price-setter") bids strategically while other firms (“non-price-setters") bid their costs. We test for asymmetries in firms' bid functions in the British spot market between 1993 and 1995 and find strong empirical support for the theory. We conclude that BFE have important implications for the design and governance of electricity markets.     

Adding ethical consideration to the decision‐making process: A leadership challenge

Stakeholder analysis offers a well‐established framework for understanding organizational context and environment. Stakeholder analysis also offers a lens through which ethical considerations can be consciously evaluated and included in organizational decision making. In this article, the author offers a brief overview of the ethics literature and then examines the decision‐making process to identify how and when opportunities arise to include ethical considerations into the decision‐making process. He concludes by offering suggestions on how leaders might improve their ethical decision‐making by using a more macro and strategic stakeholder lens.     

Wine market prices and investment under uncertainty: an econometric model for Bordeaux Crus Classés

This paper describes an econometric assessment of wine market prices for 21 of the Crus Classés châteaux in the Bordeaux region of France. The model developed in the analysis attempts to define the relationship between factors that influence wine quality and those that influence wine prices. Characteristics of the models are: (1) climate influences on grape composition (acid and sugar levels), (2) grape composition influences on market prices, (3) subjective quality evaluations (Parker‐points) on market prices, and (4) the effects of age of the wine on market prices. The results indicate that composition levels of Merlot‐dominated wines are more climate sensitive than those from Cabernet Sauvignon‐dominated wines. Overall, warm, dry summers result in high sugar and low acid levels at harvest which in turn lead to higher quality wines. Wine market price sensitivity to Parker‐point ratings indicates that properties with high Cabernet Sauvignon‐dominated wines are highly dependent on the external ratings while Merlot‐dominated wines have a decreased rating sensitivity. Smaller properties tend to gain over proportionally from high ratings indicating great jumps in price from year to year. Additionally, châteaux that have experienced high ratings for past vintages exhibit great sensitivity to point steps in ratings for current vintages. Aging has a positive effect on Bordeaux wine pricing. This is due to the increasing maturity as well as the increasing absolute scarcity. Absolute scarcity of product is expressed by the size of the property, with small properties producing less per vintage and therefore having less in the market. Additionally, Merlot‐dominated wines exhibit more maturing potential and profit more from aging than Cabernet Sauvignon‐dominated wines. Average per château real annual profit ranges from 1 to 10%. High levels of grape ripeness, absolute scarcity, and smaller properties that are dominated by Merlot in their blend lead to the highest profits. Forecasts for a vintage not yet on the market indicates that 1995 is better than 1994 for both Cabernet Sauvignon and Merlot‐dominated wines, but that 1996 and 1997 are not as good as 1995, especially for Merlot‐dominated wines.     

Developing a process for the relative valuation of R&D programmes

This paper addresses the issue of R&D programme prioritisation within a manufacturing company in the aerospace industry, in the context of an overall framework for technology management. A review of approaches to R&D project selection leads into a recent case, which describes how the company developed a practical methodology. The benefits of the process and the relevance of the academic contribution are discussed, leading to a practical checklist for in-company development of a prioritisation process.     

Local martingales, arbitrage, and viability Free snacks and cheap thrills

Summary. We revisit a standard model of security prices as Ito processes, and provide some new economic insights about the role of arbitrage and credit limits within such a model. We show that the standard assumptions of a positive state prices and existence of an equivalent martingale measure exclude prices that are viable models of competitive equilibrium and that are potentially useful for modeling actual financial markets. These models have been dismissed in the past as allowing arbitrage, but in fact an agent who prefers more to less and who has limited access to credit may have an optimum.

The Rehabilitation of Adam Smith for Catholic Social Teaching

Catholic Social Teaching (CST) takes a rather cautious view toward the value of the ideas of Adam Smith, due to his emphasis on negative political and economic liberty. Detractors of Smith within CST point to what they consider to be deficiencies within his works: an impoverished moral anthropology, a lack of concern for the common good, and markets untethered to human needs. Defenders of Smith within CST tend to emphasize the material benefits that derive from Smithian institutions, such as economic growth, improvements in standards of living, and the new opportunities that arise from cultures focused on innovation. This paper argues that Smith’s ideas have real value for CST. However, this value primarily lies in his moral psychology. While not denying the dangers of business activity for our moral lives, Smith also helps us to understand the possibility of the moral corruption of those who wield political power, thus providing an indirect defense of political and economic liberty that coheres with important Christian ethical notions found in CST. This is the case even though CST does not consistently recognize concerns surrounding the dangers of wielding political power—and thus Smith’s arguments offer real challenges to CST as well. This paper further suggests that these basic insights are relevant regardless of one’s favored institutional arrangements.     

A comparative study of the determinants of future plans and expectations of business students

Current university juniors and seniors have plans and expectations for after they graduate. In an effort to better understand these plans and expectations, the authors assessed a sample of 334 university students enrolled in business classes. The study examined the impact of three categories of independent variables—family influences, demographic influences, and academic influences—on the dependent variables of student degree aspirations, career aspirations, and expected salaries. Determinant variables with the most consistent influences on these dependent variables include birth order and parents' income (family influences); age and ethnicity (demographic influences); and grade point average, college entrance exam scores, and academic major (academic influences).     

Information shocks and the empirical evaluation of training programs during unemployment spells

We study the role of notifications in the evaluation of training programs for unemployed workers. Using a unique administrative data set containing the dates when information is exchanged between job seekers and caseworkers, we address three questions: Do information shocks, such as notification of future training, have an effect on unemployment duration? What is the joint effect of notification and training programs on unemployment? Can ignoring information shocks lead to a large bias in the estimation of the effect of training programs? We discuss these issues through the lens of a job search model and then conduct an empirical analysis following a “random effects” approach to deal with selectivity. We find that notification has a strong positive effect on the training probability but a negative one on the probability of leaving unemployment. This “attraction” effect highlights the importance of accounting for notifications in the evaluation of active labor market policies.
