The influence of linear and cyclical temporal representations on risk perception of nuclear waste: an experimental study

Time is an important aspect of the issue of nuclear waste, both from a technical and from a perceptional perspective. Previous studies have investigated the relationship between time and risk perception of nuclear waste, applying the discounting paradigm and therefore limiting time to one very narrow aspect: its duration. However, time is a multifaceted concept and encompasses more than a linear property. The aim of our study is to test the influence of a different aspect of time, namely temporal representations (linear or cyclical) on risk perception of nuclear waste. In an experimental study we demonstrate that both linear and cyclical representations have a reducing effect on risk perception compared to the control condition, where no specific time representation was activated. Examining group differences, we also demonstrate that temporal representations have a differing influence depending on whether participants have a stable belief about nuclear waste or whether they belong to an ambivalent group that does not yet hold a stable belief. Furthermore, we replicate the well-documented gender gap in risk perception. Our results bear potentially interesting implications for risk communication by demonstrating a causal relationship between the graphic representation of time and risk perception of nuclear waste.     

Vertical Foreclosure, Technological Choice, and Entry on the Intermediate Market

This paper analyzes the profitability of vertical integration for an upstream monopoly facing a potential competitor. We show that it depends on the technology used by the firm when it integrates. We distinguish two types of technologies: standard technologies, used by nonintegrated firms, and nonstandard technologies, reserved for integrated firms and implying the complete foreclosure of nonintegrated firms. Vertical integration with the adoption of a nonstandard technology dominates vertical integration with the adoption of a standard technology and is profitable, as long as the degree of competition in the downstream industry is sufficiently low.     

Will the games pay? An event analysis of the 2020 summer Olympics announcement on stock markets in Japan,Spain, and Turkey

As a wealthy, highly developed city with many existing athletic facilities, Tokyo seems uniquely placed to profit from hosting the 2020 Olympics and boost the Japanese economy. We test this hypothesis using event analysis to determine whether the holding period return on Tokyo’s Nikkei 225 stock index showed abnormal returns following the IOC’s announcement that Tokyo would host the 2020 Summer Games. We use the same technique to investigate whether the stock markets in Madrid or Istanbul – the other finalist cities – showed abnormally low holding period returns in the wake of the announcement.     

Using patents to mislead rivals

Abstract.  Firms claim they do not rely heavily on patents. Yet they patent, as indicated by the large number of patents that are granted. This paper offers a possible resolution to this puzzle. It takes a simplified version of a duopoly innovation race and studies the patenting decision of an innovator who has private information about the improvability of her innovation. It is shown that a firm may use the patenting decision to mislead her rival. Under symmetric information, research can be stimulated but not disclosed. However, under asymmetric information, disclosure is more likely, even though research incentive may be weakened. JEL Classification: 031, L1     

Storage and security of supply in the medium run

This paper analyzes the role of private storage in a market for a commodity (e.g. natural gas) whose supply is subject to the threat of an irreversible disruption. We focus on the medium term in which seasonality of demand and exhaustibility can be neglected. We characterize the price and inventory dynamics (accumulation, drainage and limit stocks) in a competitive equilibrium with rational expectations. We show the robustness of our results to alternative scenarios in which either a disruption has finite duration or the crisis is foreseen. During the crisis consumers may put pressure on the Government to intervene, but too severe antispeculative measures would inefficiently discourage storage. Practical solutions to this dilemma cause welfare losses that we characterize and quantify.     

The Institutionalization of Fair Trade: More than Just a Degraded Form of Social Action

The context of economic globalization has contributed to the emergence of a new form of social action which has spread into the economic sphere in the form of the new social economic movements. The emblematic figure of this new generation of social movements is fair trade, which influences the economy towards political or social ends. Having emerged from multiple alternative trade practices, fair trade has gradually become institutionalized since the professionalization of World Shops, the arrival of fair trade products in the food industry, and the establishment of an official “fair trade” label. With the strength that this institutionalization has generated, fair trade can now be considered a real trade system that questions, as much as it renews, the traditional economic system. In parallel, this transformation has exacerbated the tensions within the movement, which can be characterized as a clash between a “radical, militant” pole and a “softer, more commercial” one. However, it is not the actual institutionalization of fair trade which is being debated among fair trade actors on either side of the fence, but rather the challenges inherent in finding an economic institutionalization acceptable to social economic movements. Therefore the institutionalization process of fair trade should not be seen as mere degradation of social action, but rather as typical of the institutionalization process of new social economic movements. If we need to worry about the highjacking and alteration of the fair trade movement by the dominant economic system, the opposite is no less likely, as new social economic movements contribute to an ethical restructuring of markets.     

Emission Permit Trading Between Imperfectly Competitive Product Markets

The present paper analyzes the efficiency of emission permit trading between two imperfectly competitive product markets. Even if firms are price takers in permit markets, the integration of permit markets can decrease welfare because of imperfect competition in product markets. If there is asymmetric information between the regulator and firms, the integration of the permit markets could have a positive effect related to the flexibility of an integrated market; this flexibility can justify integrating the permit markets.     

Free market environmentalism and the neoliberal project: The case of the Climate Disclosure Standards Board

In the absence of good social, political, economic and environmental policy, the ecological status of the planet continues to deteriorate. In this paper, we argue that environmental decline has provided scope for new forms of policy-making, yet these emergent policies and policy-making bodies remain poorly understood. Drawing on the work of political geographers and political economists this paper explores the impact of neoliberalism on the development of global environmental regulation. We argue that climate disclosure practices and regulation have provided an opportunity to reinforce the ideological landscape of neoliberalism. In order to anchor this argument, we show that the origins of carbon regulation have emerged almost exclusively from within non-elected coalitions of multinationals operating through private, not-for-profit entities. These organisations continue to shape community expectations and influence government of climate change abatement strategies. To explore the impact neoliberalism has had on the environment, we examine the Climate Disclosure Standards Board (CDSB), its role, and its global impact on the regulation of reporting firms.
