Revealing Incentives for Compatibility Provision in Vertically Differentiated Network Industries

We determine the incentives for compatibility provision of firms that produce network goods with different intrinsic qualities when firms do not have veto power over compatibility. When network effects are strong, there are multiple equilibria in pricing and consumer decisions. We show that in some equilibria, it is the high‐quality firm that invests in compatibility, whereas in others, the low‐quality firm triggers compatibility. The socially optimal compatibility degree is zero, except under very strong network effects, where one of the equilibria has all consumers buying the low‐quality good. In this case, a partial degree of compatibility is optimal.     

Is it all about awareness? The normalization of coastal risk

Coastal risk is already high in several parts of the world and is expected to be amplified by climate change, which makes it necessary to outline effective risk management strategies. Risk managers assume that increasing awareness of coastal risk is the key to public support and endorsement of risk management strategies – an assumption that underlies a common worldview on the public understanding of science, which has been named the deficit model. We argue that the effects of awareness are not as straightforward. In particular, awareness of coastal hazards might not lead to more technically accurate risk perceptions. Based on research on risk perception normalization, we explored the hypothesis that coastal risk awareness reduces coastal risk perception – in particular the perceived likelihood of occurrence of coastal hazards – through its effect on reliance on protective measures to prevent risk. Individuals can rely on protective measures, even when those are not effective, as a positive illusion to reduce risk perception. This effect might be stronger for higher probability hazards and for permanent residents of costal zones. Data from 410 individuals living in coastal zones corroborated most of our expectations. Global results demonstrated a risk normalization effect mediated by reliance on current measures. Additional analyses made clear that this effect occurred in 2 of the 5 high-probability hazards (flood and storm), and not in the low-probability hazard (tsunami). Normalization might be more likely among high-probability hazards which entail catastrophic and immediate impacts. This effect was also found among permanent residents, but not among temporary residents. Results imply that coastal risk management might benefit from (a) taking risk perception normalization effects into account, (b) tailoring strategies for permanent and temporary residents and (c) promoting a higher public engagement, which would facilitate a more adaptive and effective coping with coastal risk than the use of positive illusions.     

The future of olive groves on sloping land and ex-ante assessment of cross compliance for erosion control

Under the past Common Agricultural Policy (CAP) olive oil subsidy regime, farmers were eligible for subsidies on the basis of the amount of olive oil they produced. This led to an intensification of production, particularly on flat land, and had in most cases negative environmental effects, such as more soil erosion on sloping land and more pollution. With the decoupling of agricultural support under the newly established rules of the CAP, formalised in 2005, cross compliance measures have become obligatory.In this paper an ex-ante assessment is made of the application of cross compliance for soil erosion control (natural cover crops and terrace maintenance) in hilly and mountainous olive groves in Trás-os-Montes in Portugal. A linear programming model was developed to assess the various socio-economic and environmental effects of four different development scenarios for olive groves. The scenarios were developed on the basis of changing market prices, wage rates and subsidies; their effects included shifts towards intensification, abandonment and organic farming. Simulations considering a minimum return to labour constraint showed very high levels of abandonment, particularly in combination with cross compliance obligations. However, even without this minimum return to labour constraint, abandonment would reach more than 20% in three out of the four scenarios. The model showed that cross compliance obligations could be quite effective in reducing erosion, but that they would depress income in all scenarios as a result of higher abandonment and lower percentage shifts towards intensive systems.     

Do price-earnings ratios explain investment decisions better than Tobin’s q? Evidence from German firm-level data

This article tests the additional information content of price-earnings ratios, with respect to Tobin’s q, in explaining firms’ investment behaviour. While Tobin’s q describes the expected future earnings related to those projected by the book value, the price-earnings ratio compares future growth of earnings based on the projection of current earnings. In other words, a high price-earnings ratio might indicate that investors are willing to rely on future earnings growth, even though current earnings are low. By using an unbalanced panel of about 500 listed firms from Germany over the period 1987–2007, we find that including the price-earnings ratio in the investment equation does not change the explanatory power of Tobin’s q. Most notably, the price-earnings ratio exerts a positive and significant impact on investment. These results are robust to the inclusion of a measure of the firm’s internal funds and of fixed effects and also to the use of different estimators.     

Contingent work in the hospitality industry: A mediating model of organizational attitudes

It is widely accepted that work status has an impact on emotional attachment to the organization, because of the different ways in which the two categories of workers, contingent and regular, are treated in the same organization. This study aims to investigate the effect of work status on affective commitment and how this relationship is influenced by identification processes.     

Intrinsic quality improvements and network externalities

We analyze the optimal pricing choice of an incumbent firm that sells a good with network externalities and is threatened by the entry of a higher intrinsic quality variant. In the framework of a vertical differentiation model, we find a necessary and sufficient condition under which intrinsic quality improvement occurs as a result of this competition.     

Determinants of Trade: the Role of Innovation in Presence of Quality Standards

This paper analyses the role that quality standards and innovation play on trade volume, by using a gravity model. The role of innovative activity and quality standards in enhancing trade performance is widely accepted in the literature. However, in this paper, we argue that the net effect of quality standards on trade is affected by the exporter’s ability to innovate and comply with these requirements. In particular, by using a sample of 60 exporting countries and 57 importing countries, for a wide range of 26 manufacturing industries over the period 1995–2000, we show that the most innovative industries are more likely to enhance the overall quality of exports, and then gain a competitive advantage. We also find that this effect depends on the level of technology intensity at industry-level and on the level of economic development of exporting country.     

Does financial development help to align growth opportunities with growth? Evidence from industry-level data

Financial institutions are expected to play a crucial role in reallocating resources in favor of industries facing greater global and local shocks to growth opportunities. Fisman and Love, in their paper entitled “Financial development and intersectoral allocation: A new approach”, argue that growth opportunities are unobservable and propose a new methodology to test the capital allocation hypothesis. The methodology is based on correlations in the patterns of intra-industry growth between two countries and similarities in the level of financial development and income. This paper extends their methodology by proposing direct and forward-looking measures of local and global growth opportunities, obtained by interacting the country’s patterns of industrial specialization with industry-level price-earnings ratios, as in the paper “Global growth opportunities and market integration” by Bekaert et al. The results, obtained in a cross-section framework including 37 developed and developing countries over the period 1992–2006, confirm the relevance of financial development to promote economic growth and to help industries in taking advantage of global and local growth opportunities. They also show that the methodology developed by Fisman and Love can be extended to include direct measures of growth opportunities.     

Revenue management policies for the truck rental industry

In this paper, we consider the problem of managing a fleet of trucks with different capacity to serve the requests of different customers that arise randomly over time. The problem is formulated via dynamic programming. Linear programming approximations of the problem are presented and their solutions are exploited to develop partitioned booking limits and bid prices policies. The numerical experiments show that the proposed policies can be profitably used in supporting the decision maker.
