Asymmetric Price Adjustments in Airlines

This paper uses a unique daily time series data set to investigate the asymmetric response of airline prices to capacity costs driven by demand fluctuations. We use a Markov regime‐switching model with time‐varying transition probabilities to capture the time variation in the response. The results show strong evidence of asymmetric price adjustments: positive cost shifts have a large positive effect, whereas negative cost shifts have no effect. The asymmetry is also explained by summer travel but not by the size of cost shifts. The findings show the importance of consumer heterogeneity and capacity constraints as a source of asymmetric responses. Copyright © 2012 John Wiley & Sons, Ltd.     

Environmental externalities and regulation constrained cost productivity growth in the US electric utility industry

This paper examines whether having to comply with Phase 1 of Title IV of the 1990 Clean Air Act, and rate of return regulation, each impacted the rate of total factor productivity (TFP) growth when accounting for the production of good and bad outputs. Phase 1, effective from 1995 to 1999, requires electric utilities to reduce their emissions of sulfur dioxide and nitrogen oxide (bad outputs). Actions undertaken to reduce the emissions (using less sulfur content coal, installing equipment), may have led to higher production costs, and impacted the rate of TFP growth. Rate regulation may impact how the firm produces its selected output level, which could lead to higher cost over time, and biased estimates of TFP growth. Following the work of Ball et al. (Struct Change Econ Dyn 16(3): 374–394, 2005), who developed the standard Malmquist cost productivity (MCP) index, we develop a MCP index for a rate regulated firm (RMCP index) then use the standard and regulated indices to determine whether having to comply with Phase 1 impacted TFP growth. Empirical results indicate that (i) the RMCP index underestimated the rate at which TFP growth occurred, (ii) Phase 1 utilities on average experienced positive TFP growth from 1996 to 2000 (Phase 1 firms experienced higher TFP growth rates than the rates experienced by firms not subject to Phase 1), and operated more allocatively inefficient in complying with the Phase 1 restrictions. Complying with Phase 1 did not affect the rate at which technical change occurred or the rates of change in scale efficiency.     

Null models of economic networks: the case of the world trade web

In all empirical-network studies, the observed properties of economic networks are informative only if compared with a well-defined null model that can quantitatively predict the behavior of such properties in constrained graphs. However, predictions of the available null-model methods can be derived analytically only under assumptions (e.g., sparseness of the network) that are unrealistic for most economic networks like the world trade web (WTW). In this paper we study the evolution of the WTW using a recently-proposed family of null network models. The method allows to analytically obtain the expected value of any network statistic across the ensemble of networks that preserve on average some local properties, and are otherwise fully random. We compare expected and observed properties of the WTW in the period 1950–2000, when either the expected number of trade partners or total country trade is kept fixed and equal to observed quantities. We show that, in the binary WTW, node-degree sequences are sufficient to explain higher-order network properties such as disassortativity and clustering-degree correlation, especially in the last part of the sample. Conversely, in the weighted WTW, the observed sequence of total country imports and exports are not sufficient to predict higher-order patterns of the WTW. We discuss some important implications of these findings for international-trade models.     

Representing markets: The shaping of fashion trends by French and Italian fabric companies

In this paper, we use ethnographic methods to describe the market making activities of Première Vision, Paris, the leading trade fair in the clothing fabric industry. Through collective action and powerful representational practices, Première Vision's exhibitors affirm their style innovation and position themselves as trend setters. Our study extends the emerging literature on market forms and marketing practices by (i) introducing a different lens, based on the ideas of postmodern theorists, through which the nature of representation in industrial markets may be viewed and (ii) addressing the role of self-interested theorists, i.e. marketers who theorize about the market and its functioning in ways that are self-beneficial. Our paper also has implications for trade fair literature, which is mostly concerned with individual exhibitors' value appropriation strategies. The case of Première Vision shows that trade fairs may be considered as collective marketing instruments, thus highlighting the importance of organizers' value creation strategies.     

Critical issues in health and wellness tourism: an exploratory study of visitors to wellness centres on Gran Canaria

The growing commodification of health care and therapeutic landscape, as well as the recent growth in international demand for wellness services and treatments, has led to the proliferation of destinations and enterprises that have selected health and wellness tourism as part of their corporate strategy, including coastal tourism destinations such as the Spanish island of Gran Canaria. This study discusses the commodification of health care and landscape, the relationship between everyday life and going on holiday, as well as the motives for medical and wellness tourism. Wellness tourism development on Gran Canaria is also analysed as a case study that could prove useful for those working on diversification within coastal tourism. An exploratory study of European visitors to wellness centres on the island is also presented. Major findings and contributions relate to socio-demographic characteristics, motives for the visit to the island, the importance of the wellness offer, tourist and travel behaviour and wellness behaviour both at the destination and at the place of residence. Another contribution refers to differences in the use of wellness centres and treatments among visitors, based on their place of origin, gender, age, marital status and job situation. Management and marketing implications are also suggested.     

Competition and open source with perfect software compatibility

In this paper we study duopolistic competition between closed and open source software. Inspired by recent contributions on open source, we propose a two-stage game with perfect information and product differentiation, in which producers first set software quality and then determine prices (the price is zero for open source programs). We assume perfect software compatibility and model lock-in effects, a network externality component of software quality, and accumulation of experience in software use and implementation. In comparison to the monopolistic benchmark case, we argue that, in a duopoly created by the emergence of an open source program, the proprietary software producer will reduce its selling price if: (i) its network of users is larger than the open source network and its consumers are largely familiar with its program, (ii) it has a small network of unskilled consumers. On the other hand, the price of proprietary software will increase if its users form a large, but poorly-skilled network. Furthermore, we show that, in all of the above cases, the hedonic quality of proprietary software increases. Finally, by modeling experience accumulation processes through difference equations, we show that the ratio between the closed and open source programs’ opportunity costs for software learning and deployment plays a crucial role in shaping market outcomes. If open source software remains too complex and technical for unskilled or time-pressed users, a shared market solution, in which both programs are adopted, is likely to emerge. However, if opportunity costs in learning and understanding open source programs are particularly low, or at least equal to the opportunity costs of a closed-source program, then open source dominance emerges (i.e. markets tip to open source).     

Sustainable tourism development in islands: a case study of Gran Canaria

While sustainable development is recognized as an essential requirement for achieving economic goals without degrading the environment, major problems arise in defining methods for formulating and implementing sustainable strategic actions at the macro‐level, including islands. Bearing in mind this limitation, this research paper will attempt to present a strategic planning methodology for drawing up strategic issues for tourism development from the point of view of sustainability, which is particularly appropriate to islands. The authors first review existing literature on sustainable development with a view to defining a conceptual approach to sustainability and identifying particular areas for sustainable tourism development in the island context. A methodology for formulating strategic issues for sustainable tourism development in Gran Canaria is then drawn up. Sociocultural aspects, the environment and the economy, with particular emphasis on tourism, are examined in order to identify major strategic issues for sustainable development in Gran Canaria.

A consistent analysis of diversification decisions with non-observable firm effects

The empirical analyses of firm diversification decisions, both for new activities (new products) and markets (for example, new routes for airlines), have usually estimated a binary dependent variable model for each of the decisions the firm makes. To obtain consistent estimators, every relevant effect must be considered in the specification. As this will hardly happen, the presence of nonobserved firm effects (either because such data do not exist or because it is impossible to obtain them) must be econometrically treated, because it causes inconsistency in the estimations. In this paper we propose to use the estimators provided by the maximization of the conditional likelihood function in problems of this kind because they give consistent results even when unobserved firm effects are present. Finally, we apply this technique to an example of diversification among Spanish manufacturers. © 1997 John Wiley & Sons, Ltd.     

Board‐level ethics committees in large European firms

After the approval of a code of ethics, the creation of a permanent board‐level ethics committee is the next step in the institutionalization of business ethics. This study explores how the board's structure and demographic characteristics explain the decision to form an ethics committee. The analysis is based on the constituents of the Standard and Poor's Europe 350 index. Consistent with our hypotheses, we find that ethics committees are more likely to be found in firms with a lower presence of executive directors and of directors holding MBA degrees. However, we also observe that boards chaired by executive directors seem to favor the creation of an ethics committee. Additionally, as we had anticipated, firms with stronger agency conflicts seem to be more willing to create committees. The analysis conducted with segmented samples reveals that the model has greater explanatory power when applied to firms from common‐law and French civil‐law countries than when applied to firms from the German–Scandinavian civil‐law area. Finally, our results indicate that a firm's country of origin is a more influential factor in explaining the decision to create an ethics committee than the industry to which it belongs or even the magnitude of its agency conflicts.
