Land, Environmental Externalities and Tourism Development

In a two sectors dynamic model we analyze the process of tourism development based on the accumulation of capital (building of tourism facilities) and the reallocation of land from traditional activities to the tourism sector. The model incorporates the conflict between occupation of the territory by the tourism facilities, other productive activities and availability of cultural, natural and environmental assets that are valued by residents and visitors. We characterize the process of tourism development in two settings: the socially optimal solution and a situation where the costs of tourism expansion are external to the decision makers, where externalities on residents as well as intraindustry externalities are considered. Regarding the optimal solution, we show that it is optimal to limit tourism expansion before it reaches its maximum capacity even in a context where the economic attractiveness of tourism relative to other productive sectors rise continuously. However, in this context and when all the costs of tourism development are externalities the only limit to tourism quantitative expansion is its maximum capacity determined by the availability of land. Finally, we show that excessive environmental degradation from the future generations’ point of view is not a problem of discounting the future but rather a problem of externalities that affects negatively the current and future generations.Intertemporal land allocation, Structural economic change, Tourism industry

Damaged Durable Goods

A durable-goods monopolist may use quality degradation as a commitment not to lower price in the future. The introduction of damaged goods expedites low-valuation consumers’ future demands, and helps the firm to mitigate the Coasian time-consistency problem. In such a case, damaged goods are more likely to be observed relative to the static setting where only the price-discrimination aspect of quality degradation is in effect. However, it is more likely to reduce welfare by inducing low- valuation buyers to buy the low-quality good early rather than to wait and buy the high-quality good later. So, quality degradation of durable goods is more likely to occur but less promising to the society, relative to the case of non-durable goods where damaged goods are rarely observed but more likely to be Pareto-improving.Damaged Goods, Quality Degradation, Durable-Goods Monopoly, Time-Consistency

Piracy of Digital Products: A Critical Review of the Economics Literature

Digital products have the property that they can be copied almost costlessly. This makes them candidates for non-commercial copying by final consumers. Because the copy of a copy typically does not deteriorate in quality, copying products can become a wide-spread phenomenon – this can be illustrated by the surge of file-sharing networks. In this paper we provide a critical overview of the literature that addresses the economic consequences of end-user copying. We conclude that some models with network effects are well-suited for the analysis of software copying while other models incorporating the feature that copies provide information about the originals may be useful for the analysis of digital music copying.information good, piracy, copyright, internet, peer-to-peer, software, music

Vertical foreclosure: a policy framework

Whenever you phone your mother, switch on the light, or buy health insurance you purchase a service or product from a chain of vertically related industries. Providers of these products or services need access to a telecommunications network, an electricity network or to health care services. In such industries, integration and exclusive contracts between vertically related firms may have important welfare enhancing effects, but can also deny or limit rivals' access to input or customers, leading to foreclosure. Foreclosure can harm welfare if it reduces competition. This document provides policymakers with a framework to assess the potential for welfare reducing foreclosure of vertical integration and vertical restraints and describes possible remedies. The framework consists of four steps. Each step requires its own detailed analysis. First, market power should exist either upstream or downstream. Second, a theory of foreclosure should be formulated that explains why foreclosure is a profitable equilibrium strategy. Third, the existence and magnitude of potential welfare enhancing effects of the vertical restrains or vertical integration should be assessed. Fourth, suitable policies to address foreclosure should be found.

Innovation, Licensing and Welfare

This paper examines how the option for licensing affects research and development (R&D) and social welfare. We find that if cost reduction from R&D is sufficiently small and there is an option of licensing, firms will do non-cooperative R&D. In absence of licensing, firms will do cooperative R&D for sufficiently small cost reduction from R&D. Whether the option for licensing increases social welfare is ambiguous. If the possibility of licensing increases probability of success in R&D significantly then welfare is higher in presence of licensing.Cooperative R&D, Licensing, Welfare

From growth to green growth -- a framework

Green growth is about making growth processes resource-efficient, cleaner and more resilient without necessarily slowing them. This paper aims at clarifying these concepts in an analytical framework and at proposing foundations for green growth. The green growth approach proposed here is based on (1) focusing on what needs to happen over the next 5-10 years before the world gets locked into patterns that would be prohibitively expensive and complex to modify and (2) reconciling the short and the long term, by offsetting short-term costs and maximizing synergies and economic co-benefits. This, in turn, increases the social and political acceptability of environmental policies. This framework identifies channels through which green policies can potentially contribute to economic growth. However, only detailed country- and context-specific analyses for each of these channels could reach firm conclusion regarding their actual impact on growth. Finally, the paper discusses the policies that can be implemented to capture these co-benefits and environmental benefits. Since green growth policies pursue a variety of goals, they are best served by a combination of instruments: price-based policies are important but are only one component in a policy tool-box that can also include norms and regulation, public production and direct investment, information creation and dissemination, education and moral suasion, or industrial and innovation policies.Environmental Economics&Policies,Climate Change Economics,Economic Theory&Research,Transport Economics Policy&Planning,Labor Policies

Asymmetry and Discrimination in Internet Peering Evidence from the LINX

Is the quality of interconnection between Internet operators affected by their asymmetry? While recent game theoretic literature provides contrasting answers to this question, there is a lack of empirical research. We introduce a novel dataset based on Internet routing policies, and study the interconnection decisions amongst the Internet Service Providers (ISPs) members of the London Internet Exchange Point (LINX). Our results show that interconnection quality degradation can be significantly explained by asymmetry between providers. We also show that Competition Authorities should focus more on the role played by the “centrality of an operatorâ€, rather than on its market share.Internet Peering, Two-sided Markets, Network Industries, Antitrust, Net Neutrality

Economic Policy for Sustainable Growth and Development vs. Greedy Growth and Preservationism

Sustainability science emerged from the felt need to employ appropriate science and technology in the pursuit of sustainable development. The existing sustainability science agenda emphasizes the importance of using a systems approach, stressing the many interactions between natural and human systems. Despite its inertia and avowed purpose of being practical and feasible, however, sustainability science has yet to embrace the policy sciences. In pursuit of this objective, we first trace the history of thought of sustainable development, including its definition and operationalization. Sustainable development encompasses sustainable growth and dynamically efficient development patterns. Two promising approaches to sustainable growth are contrasted. Negative sustainability counsels policy makers to offset any decrease in natural capital with at least the same value of net investment in produced capital. This sustainability criterion cannot determine how and how much to conserve natural capital nor how much to build up human and productive capital. Indeed, there is ambiguity regarding what prices to use in summing the values of diverse capital assets. To fill the void, we offer positive sustainability, which maximizes intertemporal welfare while incorporating system linkages, dynamic efficiency, and intertemporal equity. This provides a solid and operational framework for sustainable growth. In addition, sustainable development must include the lessons from development theory, including how optimal patterns of production, consumption, and trade change with standards of living. However, like Tolstoy’s unhappy families, there are many pathways to unsustainable development. We describe two broad causes of unsustainable growth – rent-seeking and preservationism. We also illustrate patterns of unsustainable development by drawing on lessons from the Philippines. While specialization is the engine of growth, fragmentation is the anchor. In addition to natural fragmentation from natural trade barriers in an island archipelago, policy and governance, driven by rentseeking, promote economic stagnation. Low economic growth in turn exacerbates population pressure and environmental degradation—the vicious circle of unsustainable development. We give particular attention to how a resource curse can exacerbate policy distortions and rent-seeking, and how the same phenomenon can be promulgated by foreign aid, foreign direct investments, remittances, and tourism. For sustainable development not to be at odds with policy science, positive sustainability must be combined with projects and policies that promote dynamic comparative advantage and poverty reduction. We emphasize the facilitative role of government especially in transforming the vicious circle into a virtuous circle.Sustainable development and patterns, positive sustainability, specialization, the Philippines
