The Diffusion of Wal‐Mart and Economies of Density

The rollout of Wal‐Mart store openings followed a pattern that radiated from the center outward, with Wal‐Mart maintaining high store density and a contiguous store network all along the way. This paper estimates the benefits of such a strategy to Wal‐Mart, focusing on the savings in distribution costs afforded by a dense network of stores. The paper takes a revealed preference approach, inferring the magnitude of density economies from how much sales cannibalization of closely packed stores Wal‐Mart is willing to suffer to achieve density economies. The model is dynamic with rich geographic detail on the locations of stores and distribution centers. Given the enormous number of possible combinations of store‐opening sequences, it is difficult to directly solve Wal‐Mart's problem, making conventional approaches infeasible. The moment inequality approach is used instead and works well. The estimates show the benefits to Wal‐Mart of high store density are substantial and likely extend significantly beyond savings in trucking costs.     

What Happens When Wal‐Mart Comes to Town: An Empirical Analysis of the Discount Retailing Industry

In the past few decades multistore retailers, especially those with 100 or more stores, have experienced substantial growth. At the same time, there is widely reported public outcry over the impact of these chain stores on other retailers and local communities. This paper develops an empirical model to assess the impact of chain stores on other discount retailers and to quantify the size of the scale economies within a chain. The model has two key features. First, it allows for flexible competition patterns among all players. Second, for chains, it incorporates the scale economies that arise from operating multiple stores in nearby regions. In doing so, the model relaxes the commonly used assumption that entry in different markets is independent. The lattice theory is exploited to solve this complicated entry game among chains and other discount retailers in a large number of markets. It is found that the negative impact of Kmart's presence on Wal‐Mart's profit was much stronger in 1988 than in 1997, while the opposite is true for the effect of Wal‐Mart's presence on Kmart's profit. Having a chain store in a market makes roughly 50% of the discount stores unprofitable. Wal‐Mart's expansion from the late 1980s to the late 1990s explains about 40–50% of the net change in the number of small discount stores and 30–40% for all other discount stores. Scale economies were important for Wal‐Mart, but less so for Kmart, and the magnitude did not grow proportionately with the chains' sizes.     

Prescription Drug Labeling and “Over‐Warning”: The Disturbing Case of Diana Levine and Wyeth Pharmaceutical

In April of 2000, Diana Levine went to a clinic in Vermont suffering from a migraine headache. She was given the drug Demerol for the migraine symptoms and Phenergan for nausea. Complications with the administration of Phenergan ultimately resulted in Ms. Levine contracting gangrene, necessitating the amputation of her right arm. Ms. Levine sued the drug maker, Wyeth Pharmaceutical, in state court and prevailed. The lower court's decision was appealed by Wyeth to the state supreme court where the ruling was confirmed. Wyeth next appealed to the U.S. Supreme Court which, to the surprise of many observers, affirmed the judgment of the state supreme court. At issue was the fundamental question of the ability of consumers to obtain redress against negligent manufacturers in state courts. Wyeth's arguments to the Court were based upon preemption: Foodand Drug Administration (FDA) approval of a drug (and its labeling) preempts the ability of injured consumers like Ms. Levine to recover in state courts despite years of precedent to the contrary. Ability to recover damages in state courts represents, perhaps, the most important safety net available to consumers injured by defective products. A ruling by the Supreme Court that FDA‐approved labeling of pharmaceuticals preempts the reach of the state courts would have severely compromised the balance of power between consumers and producers.     

A Brief Review and Assessment of the Leegin Decision: Who Wins and Who Loses When Manufacturers Are Free to Set Retail Prices?

For decades, it has been a per se violation of U.S. antitrust law for manufacturers or distributors to specify retail selling prices. In the spirit of atomistic, unrestrained competition, retailers were free to set prices without undue interference from upstream channel participants. Attempts by manufacturers or other channel participants to restrict retail price setting initiatives were viewed by regulators as an unwarranted and illegal interference with the market mechanism. Restrictions on price setting initiatives would, it was argued, lessen competition and ultimately raise prices above competitive levels to the detriment of consumers. Recently, under the leadership of newly appointed Chief Justice Roberts, a more “business friendly” Supreme Court has reversed this policy; vertical price fixing is no longer a per se violation of U.S. antitrust law. By a five‐to‐four margin, the Court held in Leegin Creative Leather Products that manufacturers could, under certain circumstances, establish binding retail selling prices. Henceforth, retail price setting restrictions will be subject to a rule of reason evaluation whereby price restrictions will be assessed on a case‐by‐case basis. Proponents of the now‐legal restrictions argue that this will ensure that merchandise sold through retail outlets will receive needed support, free riding will be reduced or eliminated, and new brand introduction will be facilitated. Critics argue that the Court's decision marks a return to the days of fair trading; marginal firms will be protected, so‐called “inframarginal consumers” will be forced to pay for services they do not want or need, and prices for many branded products will rise, all to the detriment of consumer welfare.     

The Gender Wage Gap in the Turkish Labor Market

Abstract. This paper examines the sources of the gender wage gap in the Turkish labor market by using matched employer–employee data and the standard wage regression estimations as well as the Oaxaca decomposition method. The extensive number of variables in the data set enables a thorough quantitative analysis of the role of various individual‐ as well as firm‐related factors leading to wage differentials between men and women, namely human capital endowments including job tenure, occupational and industrial segregation, private/public sector location, coverage of the workplace under collective labor bargaining, and firm size. It also examines the extent of gender‐based industry and occupational segregation within the confines of data set and computes the Duncan & Duncan segregation index. We find that a large portion of the gender wage gap is attributable to women's considerably lower levels of work experience and job tenure. Other important variables that lead to pay differentials are women's lower concentration in jobs covered by collective labor bargaining and a substantial degree of occupational and industrial segregation. The differential rates of return to many of the wage determinant variables are also found to be significant in the formation of the gender wage gap.     

Equitable Taxation and the Provision of Health Insurance Subsidies

Current U.S. income tax laws allow many taxpayers to exclude from taxable income part or all of the cost of acquiring health insurance through an employer‐sponsored benefit plan. This favorable tax treatment generally applies regardless of whether the employer or employee actually pays the health insurance premiums. We describe the effects of this tax policy on the U.S. tax system's horizontal and vertical equity. We also explain how taxpayers covered by employer‐sponsored plans are significantly subsidized by the government in acquiring health insurance, whereas taxpayers who acquire health insurance by other means or who are not covered by health insurance at all receive no such government assistance. We conclude that any prospective health‐care policy initiatives, including modifications to the 2010 health‐care reforms, should contemplate both the horizontal and vertical equity of the tax treatment of health insurance premiums.     

Do Business Leaders Have Role‐Model Obligations to Be Good Political Actors?

This article raises an issue about corporate political activity that is different from those typically addressed by business ethicists. It examines the role‐model status and obligations of the business leaders who direct such activity. This approach has two potential benefits. First, since ethicists often appeal to role‐model obligations and many are concerned about corporate political activity, business ethics literature would benefit from expanding the examination of role‐model status and obligations to encompass the business leaders who direct political activity. Second, it will help ethicists determine what we should demand from business leaders who direct such activity. This is important given the U.S. Supreme Court's Citizens United decision in 2010 that guarantees corporations the free‐speech right to make political expenditures in support of political causes. I seek to demonstrate that we should hold business leaders morally accountable for how they direct political activity because of their role‐model status that arises from their greater fame, authority, or power than ordinary persons possess.     

A case of wrongful use of quality management. Summit Health, Ltd., v. Pinhas

Summit Health, Ltd., v. Pinhas liberalized the jurisdiction of the Sherman Antitrust Act to include cases of intrastate hospital credentialing. The U.S. Supreme Court decision eased the requirements for plaintiffs to sue when they perceived that health care organizations were acting as monopolies. The court removed the defense that a plaintiff had to prove that the decision of a health care organization affected interstate commerce for the case to be heard in court. Important as the case is in antitrust law, however, greater lessons can be gained by health care organizations from analyzing the events that led to the lawsuit.     

The Supreme Court rules: the FDA and tobacco regulation

The United States Supreme Court recently ruled that the U.S. Food and Drug Administration does not have the legal authority to regulate tobacco products. This ruling significantly affects public health efforts to reduce tobacco addiction, especially among the nation's youth. This decision has broader health implications as well, since tobacco-related diseases are among many of the top ten leading causes of death. Paradoxically, this decision comes at a time where states are developing new health programs to address tobacco-related illnesses using funds from the landmark tobacco lawsuit.     

Examining the Antecedents and Consequences of CIO Strategic Decision‐Making Authority: An Empirical Study*

Despite the strategic importance of information technology (IT) to contemporary firms, chief information officers (CIO) often still have varying degrees of strategic decision‐making authority. In this study, we apply the theory of managerial discretion to define CIO strategic decision‐making authority and argue that the CIO's level of strategic decision‐making authority directly influences IT's contribution to organization performance. We also draw on the power and politics perspective in the strategic decision‐making literature to identify the direct antecedents to the CIO's strategic decision‐making authority. A theoretical model is presented and empirically tested using survey data collected from a cross‐industry sample of 174 matched pairs of CIOs and top business executives through structural equation modeling. The results suggest that organizational climate, organizational support for IT, the CIO's structural power, the CIO's level of strategic effectiveness, and a strong partnership between the CIO and top management team directly influence the CIO's level of strategic decision‐making authority within the organization. The results also suggest that the CIO's strategic decision‐making authority in the organization directly influences the contribution of IT to firm performance and that effective CIOs have a greater influence on IT's contribution when provided with strategic decision‐making authority.     

Bank Loan Officers' Perceptions of Business Owners: The Role of Gender

There is a widely held belief that banks may be discriminating against female business owners. This study was designed to explore the perceptions held by bank loan officers of male and female business owners, using Bourdieu's theory of practice and Kelly's personal construct methodology. The research literature might lead to an expectation that the characteristics of the business owners would be relatively homogenous but that men and women business owners would be construed differently (for example women might be seen to lack drive). However, the results demonstrate heterogeneity in the constructs held by bank loan officers, and a particular concern with the character of the business owner. Significant gender differences were observed in only 20 of the 325 constructs elicited from 35 bank loan officers. Female bank loan officers were as likely as male bank loan officers to draw gender distinctions between business owners. Detailed multivariate analyses confirmed no evidence of systematic gender differences in the constructs held by bank loan officers of business owners.     

STOCK LEVELS AND DELIVERY RATES IN VENDORMANAGED INVENTORY PROGRAMS

Using the latest information technology, powerful retailers like Wal‐Mart have taken the lead in forging shorter replenishment‐cycles, automated supply systems with suppliers. With the objective to reduce cost, these retailers are directing suppliers to take full responsibility for managing stocks and deliveries. Suppliers' performance is measured according to how often inventory is shipped to the retailer, and how often customers are unable to purchase the product because it is out of stock. This emerging trend also implies that suppliers are absorbing a large part of the inventory and delivery costs and, therefore, must plan delivery programs including delivery frequency to ensure that the inherent costs are minimized. With the idea to incorporate this shift in focus, this paper looks at the problem facing the supplier who wants quicker replenishment at lower cost. In particular, we present a model that seeks the best trade‐off among inventory investment, delivery rates, and permitting shortages to occur, given some random demand pattern for the product. The process generating demand consists of two components: one is deterministic and the other is random. The random part is assumed to follow a compound Poisson process. Furthermore, we assume that the supplier may fail to meet uniform shipping schedules, and, therefore, uncertainty is present in delivery times. The solution to this transportationinventory problem requires determining jointly delivery rates and stock levels that will minimize transportation, inventory, and shortage costs. Several numerical results are presented to give a feel of the optimal policy's general behavior.     

Trust,Morality, and the Privatization of Water Services in Developing Countries

This article examines the business of water privatization and the ethics implied in the transformation of the water services sector in developing countries. Drawing on data derived from field visits and semi‐structured interviews held with members of government, nongovernmental organizations, and other stakeholders in one country undergoing transformation in this sector, Ghana, the article considers the ethical perspectives of the various involved stakeholders. The analysis draws on three perspectives—Gilligan's ethic of care, Rawls’ principles of justice, and virtue ethics—which together highlight the economic, class, and gender‐based dimensions of the privatization debate. Finding that endemic mistrust characterizes this debate, the article considers what is needed to re‐instill trust among stakeholders. Specific implications are provided for business leaders and government policymakers.     

Competing on Time: An Integrated Framework to Optimize Dynamic Time‐to‐Market and Production Decisions

This study develops a comprehensive framework to optimize new product introduction timing and subsequent production decisions faced by a component supplier. Prior to market entry, the supplier performs process design activities, which improve manufacturing yield and the chances of getting qualified for the customer's product. However, a long delay in market entry allows competitors to enter the market and pass the customer's qualification process before the supplier, reducing the supplier's share of the customer's business. After entering the market and if qualified, the supplier also needs to decide how much to produce for a finite planning horizon by considering several factors such as manufacturing yield and stochastic demand, both of which depend on the earlier time‐to‐market decision. To capture this dependency, we develop a sequential, nested, two‐stage decision framework to optimize the time‐to‐market and production decisions in relation to each other. We show that the supplier's optimal market entry and qualification timing decision need to be revised in real time based on the number of qualified competitors at the time of market‐entry decision. We establish the optimality of a threshold policy. Following this policy, at the beginning of each decision epoch, the supplier should optimally stop preparing for qualification and decide whether to enter the market if her order among qualified competitors exceeds a predetermined threshold. We also prove that the supplier's optimal production policy is a state‐dependent, base‐stock policy, which depends on the time‐to‐market and qualification decisions. The proposed framework also enables a firm to quantify how market conditions (such as price and competitor entry behavior) and operating conditions (such as the rate of learning and inventory/production‐related costs) affect time‐to‐market strategy and post‐entry production decisions.     

Venice Hospital decision vacated. Key Enterprises of Delaware, Inc. v. Venice Hospital

The United States Court of Appeals for the Eleventh Circuit recently ordered an en banc rehearing of its widely reported hospital downstream diversification antitrust case. The so-called Venice Hospital case had found antitrust liability in the operation of a durable medical equipment (DME) joint venture between a hospital and a DME vendor. The Eleventh Circuit, however, has vacated its prior decision and, pending its en banc opinion, reinstated the district court's decision that the defendants did not violate antitrust law.     

The Good,the Bad,and the Ugly of Corporate Personhood and Corporate Political Spending: Implications for Shareholders

In the Citizens United v. Federal Election Commission (2010) decision, the Supreme Court rendered an opinion verifying the legality of unions and corporations to spend funds from their general treasuries to finance independent expenditures related to political and electioneering communications. Such speech and communications are constitutionally protected by the First Amendment, according to Justice Kennedy, who wrote the majority opinion (558 U.S. 22, 2010). The dissenting opinion questioned whether such rights should accrue to corporations, since corporations differ from constitutionally‐protected “natural persons” (dissent, 558 U.S. 50 at 2, 2010; Johnson 2011 ). The decision ignited a firestorm of controversy, which renewed interest in the legal concept of corporate personhood. This article reviews key findings in the Citizens United v. FEC case, then describes the historical, legal, and theoretical concepts of corporate personhood with the goal of unbundling the nuanced consequences of the majority and dissenting opinions of the Citizens United v. FEC case. The analysis then turns to a shareholder perspective, with particular emphasis on the implications for shareholders’ rights and responsibilities. It concludes with an exploration of options available to shareholders concerned about how to respond when a corporation uses its resources to communicate political opinions at odds with their own.     

Does Rent‐sharing Profit Female and Male Workers? Evidence from Israeli Matched Employer–Employee Data

This paper analyses the impact of workplace characteristics on individual wages based on a unique cross‐section matched employer–employee data set for the Israeli private manufacturing sector in 1995. Specifically, we examine the effects of the interaction between profit‐sharing and wages on the gender wage gap. The empirical findings show that individual compensation is significantly and positively correlated with firms’ profits‐per‐employee, even when controlling for all of the following: group effects in the residuals, individual and firms’ characteristics, industry wage differentials and endogeneity of profits. Wage–profit elasticity is found to be 11 per cent and it does not significantly differ between genders. With respect to the overall gender wage gap (on average women earn 28 per cent less than men), the results show that within firms there is no gender discrimination and that 12 per cent of this gap can be explained by the wage–profits profile and by the fact that women are more likely to be employed in less profitable firms than men.     

Comparisons in Gender Wage Differentials and Discrimination between Germany and the United Kingdom

Due to the lack of consistent data, direct and robust comparisons of cross‐country labour markets have been virtually impossible. This study uses a new panel data series that controls for inconsistencies, thus overcoming this problem. This study estimates gender wage differentials and gender discrimination in the German and UK labour markets. Panel estimates are used to identify general wage differences between the two countries, with cross‐sectional comparisons undertaken to identify changes that have occurred between 1991 and 1993, that are consistent with known labour market policies. It is found that gender wage differentials are greater in the UK than Germany with employer discrimination against females attributed with the majority of the difference in both countries.     

Supply Chain Sourcing Under Asymmetric Information

We study a supply chain with two suppliers competing over a contract to supply components to a manufacturer. One of the suppliers is a big company for whom the manufacturer's business constitutes a small part of his business. The other supplier is a small company for whom the manufacturer's business constitutes a large portion of his business. We analyze the problem from the perspective of the big supplier and address the following questions: What is the optimal contracting strategy that the big supplier should follow? How does the information about the small supplier's production cost affect the profits and contracting decision? How does the existence of the small supplier affect profits? By studying various information scenarios regarding the small supplier's and the manufacturer's production cost, we show, for example, that the big supplier benefits when the small supplier keeps its production cost private. We quantify the value of information for the big supplier and the manufacturer. We also quantify the cost (value) of the alternative‐sourcing option for the big supplier (the manufacturer). We determine when an alternative‐sourcing option has more impact on profits than information. We conclude with extensions and numerical examples to shed light on how system parameters affect this supply chain.
