'Once I Get You Up There, Where the Air is Rarified': Health, Safety and the Working Conditions of Airline Cabin Crews

The working environment of the modern aircraft and the conditions in which airline cabin crews operate are issues which have been largely ignored in the industrial relations literature. This article considers recent trends in airline industrial relations and argues that the aircraft cabin is host to a number of hazards which pose serious threats to the health and safety of those who work in it.     

Rollover Risk and Market Freezes

The debt capacity of an asset is the maximum amount that can be borrowed using the asset as collateral. We model a sudden collapse in the debt capacity of good collateral. We assume short‐term debt that must be frequently rolled over, a small transaction cost of selling collateral in the event of default, and a small probability of meeting a buy‐to‐hold investor. We then show that a small change in the asset's fundamental value can be associated with a catastrophic drop in the debt capacity, the kind of market freeze observed during the crisis of 2007 to 2008.     

The stability of cigarette demand

The relative effects of various governmental interventions upon cigarette consumption is important to policy-makers. Historically, the demand for cigarettes has been quite unstable. Previous studies employ fixed parameter models and use dummy variables associated with interventions to stabilize the demand function. In contrast, we use a varying parameter model aplied to data from the United States for 1953–84 to investigate the stability of demand and show that the demand function is stabilized when dummy variables are employed. Our results suggest that industry advertising increases aggregate consumption while government interventions decrease it. However, the marginal effect of government warnings seems to be small, at least in the US: while the effect of the 1964 health warning is statistically significant, the effect of the 1979 health warning is not.     

The Licensing of Market Development Rights within Technology Alliances: A Shareholder Value Perspective*

Technology alliances create market development rights that are shared between partners in an alliance relative to codeveloped product technology. Alliance partners will often manage the shared market development rights in a cooperative manner by forming an agreement in which one partner (i.e., the licensor) licenses its market development rights to the other partner in the alliance (i.e., the licensee). The real options and bargaining power literatures provide opposing recommendations regarding whether a licensor creates greater shareholder value by licensing its market development rights to the licensee on a more or less restrictive basis. Empirical analysis of technology alliance contracts reveals that the restrictiveness by which a licensor should license its market development rights to a licensee depends on the licensee's strategic marketing emphasis. Specifically, a licensee will create greater value by following a more restrictive distribution strategy when its partner's marketing strategy emphasizes value creation. Alternatively, a licensee will create greater value when its partner's marketing strategy emphasizes value appropriation by following a less restrictive distribution strategy. From a theoretical perspective, the paper's findings provide early evidence regarding the contribution of marketing strategy toward value creation in technology alliances and help resolve the differing expectations offered by the real options and bargaining power literatures. Managerially, the paper identifies an alliance partner's strategic marketing emphasis as a hitherto unrecognized factor determining when managers should follow a more or less restrictive distribution strategy when licensing marketing development rights within technology alliances.     

Trader Survival: Evidence from the Energy Futures Markets

This study analyzes the adaptation of traders and the determinants of trader survival during a period of changing market structures. Our unique sample of transactions level data covers the introduction of electronic trading in the NYMEX energy futures market. The results show that most floor traders adapted to the side‐by‐side electronic and open outcry trading, although trader attrition increased and the profitability of surviving traders declined dramatically. It is also found that trading profits, trader experience and sophistication, and dual trading have a positive effect on the probability of trader survival. Scalpers are less likely to exit trading in pure open outcry trading, but are more likely to fail than traders who hold open positions longer in side‐by‐side trading. Finally, traders trading in multiple energy futures markets and those who use both the exchange floor and electronic trading appear to have a survival advantage in side‐by‐side trading. © 2011 Wiley Periodicals, Inc.

Convergence and the Caribbean

This paper examines the convergence experience of selected Caribbean countries. It examines evidence of reduced dispersion in real per capita income—Sigma convergence—and ‘catch up’ growth across the group—Beta convergence. Estimation of the Solow—Swan cross-section model for the Caribbean shows weak evidence of β and σ convergence. However, structural instability and evidence of divergence over the sample period, suggest this convergence to be spurious. Further tests on individual country data showed an absense of steady state convergence for any country over time. Institutional structures and adjustments to economic shocks appear to have been important for the determination of per capita income in the long run.

The Use of Debt and Equity in Optimal Financial Contracts

We consider risk-neutral firms that must obtain external finance. They have access to two kinds of stochastic investment opportunities. For one, return realizations are costlessly observed by all agents. For the other, return realizations are costlessly observed only by the investing firm. We examine the optimal allocation of investment between the two projects and the optimal contract used to finance it. The optimal contractual outcome can be supported by appropriate (and determinate) quantities of debt and equity issues. Investments in projects with CSV problems are associated loosely with debt. Investments in projects with observable returns are associated with equity. Journal of Economic Literature Classification Numbers: G21, E51.     

Sustainable valley entrepreneurial ecosystems

This research examines the applicability of the entrepreneurial ecosystem literature to the development of a ‘ustainable valley’, whereby a community becomes a centre for entrepreneurial innovations. Specifically, this research explores how components of the formal and informal network, physical infrastructure and culture within a community could contribute to a sustainable entrepreneurial ecosystem. One community, Victoria, British Columbia, is utilized to lay out the framework for the infrastructure necessary to create such a system. Copyright © 2005 John Wiley & Sons, Ltd and ERP Environment.
