Using Laboratory Experiments in Logistics and Supply Chain Research

Laboratory experiments provide an underutilized methodology for subjecting research in logistics and supply chain management to rigorous scientific scrutiny. As discussed in this paper, by following established procedures researchers can create an economic system in which behavior can be observed and replicated. With the ability to control the institution and the environment, researchers have complete information and can exogenously manipulate treatment variables, neither of which may be feasible in field work. We also address many of the reservations that skeptics of laboratory experiments often express including issues of realism, participant sophistication, and payoff stakes. We then provide several examples where experiments have been used to study issues relevant to logistics and supply chain management including auctions, wholesale practices in gasoline markets, inventory replenishment, liberalization of the electric power industry, and deregulation of the natural gas markets. Finally, we identify several additional areas where laboratory experiments could be informative.     

The Future of Privacy: A Consumer‐Oriented Approach to Managing Personal Data Online

Beginning with Facebook's recent controversial “tweaks” to its privacy policy and its promise to support users against employers and others who attempt to compel users to divulge passwords, we critically review European Union (EU) and US digital privacy initiatives. Whereas the EU proposal relies on legislative regulation, the United States proposes industry self‐regulation partially enforceable by the Federal Trade Commission (FTC). We conclude that not only do the sharply differing EU and US approaches present significant problems of global digital interoperability, but neither proposal promises to result in practical and feasible consumer protection, at least not in the near term. Moreover, the EU proposal poses serious threats to the profitability of digital commerce. As an alternative, we propose a “third approach,” empowering the individual digital consumer/user through a personal online strategy we call “wide‐open privacy,” which provides security without sacrificing the transformative economic, cultural, and personal benefits of the Internet. © 2013 Wiley Periodicals, Inc.     

Dynamics and equilibrium in a structural model of wide‐body commercial aircraft markets

This paper develops and estimates a dynamic equilibrium model of the market for new and used commercial aircraft. The model is estimated by maximum simulated likelihood using data on wide‐body aircraft owners and prices for transactions occurring 1978‐1997. The importance of explicitly modeling dynamics and equilibrium in new and used markets for durable goods is illustrated in two counterfactual experiments. Estimates of the structural model are used to show that implementing an investment tax credit not only increases demand for new wide‐body aircraft by the airlines that receive the tax credit, but also increases the number of new wide‐body aircraft owned by airlines not directly affected by the policy. Further, the model indicates that a policy which improves the efficiency of secondary markets for used wide‐body aircraft will also stimulate demand for new wide‐body aircraft.

Poverty and unemployment: A cultural approach

For years, policymakers, business leaders, human resources professionals, and economists have attempted to explain the existence of unemployment. Unemployment inhibits the economic growth of a nation and contributes to the problem of ongoing poverty, which cannot be lessened without that growth. Understanding the causes of unemployment and developing policies and programs to decrease it are vitally important for nations around the world, but one key variable in the study of unemployment has been overlooked. That variable is culture. This article will show that culture can significantly explain cross‐national differences in unemployment rates and offers a link to understanding the global problem of poverty that plagues nations today. © 2012 Wiley Periodicals, Inc.     

Regaining Missed Opportunities: The Role of Tourism in Post-war Development in Sri Lanka

Sri Lanka had the opportunity to become one of the best tourism countries (TCs) in Asia immediately after independence in 1948. However, it missed opportunities on a number of occasions due to inappropriate economic policies, continuous political violence and war. Between 1983 and May 2009 the Sri Lankan tourism sector was seriously affected by nearly three decades of separatist war. Immediately after the end of the war, tourism in Sri Lanka bounced back and it has now become one of the main engines of economic growth in post-war Sri Lanka. In this article, a historical analysis has been undertaken to demonstrate how, despite its large tourism potential, Sri Lanka missed opportunities and fell far behind its Asian counterparts on a number of occasions. This article demonstrates that opportunities exist for the Sri Lankan tourism sector to play a vital role in the current post-war inclusive development strategy in terms of generating much needed foreign exchange, poverty alleviation via employment generation, accelerating economic growth and uplifting living standards of all Sri Lankans.     

Processing and Retrieval of Inferences and Descriptive Advertising Information: The Effects of Message Elaboration

Abstract

Two issues make advertising effectiveness difficult to assess: (1) advertising effects occur both during ad processing and when ad information is retrieved, and (2) the information that consumers derive from advertisements is likely to be some combination of explicit information and inferences. The study reported in this paper addresses these issues, examining the effects of encoding and time delay on advertising processing. Results indicate that while some types of inferences (product features) are more likely to be made under strong than weak encoding conditions, other types of inferences (consumption situation) are not affected by encoding. In addition, at the time of a decision (after a time delay), memory information use depends both upon individual brand accessibility and the relative accessibility of alternative brands in the memory set. Implications for both advertising researchers and managers are offered.     

The Exploitation of Inside Information at the Wall Street Journal: A Test of Strong Form Efficiency

The study examines if tradings on stocks based on the inside information about the “Heard on the Street” column of the Wall Street Journal could generate abnormal returns. We found significant abnormal returns on days t =?1 and t= 0 (publication date) for the stocks related to insider trading. For a comparable control group of noninsider traded stocks, the abnormal returns were not significant on day t=?1 but were significant on day t= 0. The abnormal returns for the insider trade group on days t=?1 and t= 0 were greater than the returns for the control group. The results indicate that the inside information was the cause for the differences.
