The Permissible Reach of National Environmental Policies

Trading nations exchange tariff concessions in the context of trade liberalizing rounds. Tariffs, nonetheless, are not the only instrument affecting the value of a concession. Domestic instruments affect it as well, but public order is not negotiable, and, consequently, is not scheduled. Public order is unilaterally defined, but must respect the default rules concerning allocation of jurisdiction which are common to all WTO Members and bind them by virtue of their appurtenance to the international community. In this paper, we focus on the interaction between trade and environment. The purpose of this study is to highlight how these rules and the GATT/WTO jointly determine the scope for unilateral environmental policies for WTO Members. In the study we examine the relevant multilateral framework dealing with this issue, as well as the relevant GATT and WTO case-law. We also briefly present the jurisdictional default rules in Public International Law. As a means of focusing the discussion, we consider a series of scenarios, partly building on factual aspects of cases that have already been brought before the WTO. These scenarios are intended to isolate issues of specific interest from a policy point of view. For each scenario we then seek to determine what would the outcome be, in case WTO adjudicating bodies were to explicitly take account of the default rules concerning allocation of jurisdiction, something which has not been done to date. Our main conclusions are two-fold: on occasion, the outcome would be different, had WTO panels observed the default rules concerning allocation of jurisdiction; more generally, the default rules can help us understand the limits of some key obligations assumed under the WTO. Crucially, absent recourse to the default rules concerning allocation of jurisdiction, one risks understanding non-discrimination (the key GATT-obligation) as an instrument aimed to harmonize conditions of competition across markets, and not within markets, as the intent of negotiators has always been.Trade and Environment; WTO

Product Differentiation in Successive Vertical Oligopolies

This is a successive oligopoly model with two brands. Each downstream firm chooses one brand to sell on a final market. The upstream firms specialize in the production of one input specifically designed for the production of one brand, but they also produce the input for the other brand at an extra cost. We show that when more downstream firms choose one brand, more upstream firms will specialize in the input specific to that brand, and vice versa. Hence, multiple equilibria are possible and the softening effect of brand differentiation on competition might not be strong enough to induce maximal differentiation. The existence of equilibria and their welfare performance are also examined.Product differentiation, Vertical relationships, Oligopoly

IDENTITY PRESERVATION AND FALSE NON-GMO LABELING IN THE FOOD SUPPLY CHAIN

This paper addresses two issues pertaining to the market differentiation between non-genetically modified and genetically modified food varieties. First, a cost-efficiency explanation of the discrepancy between the observed shares of identity preserved non-genetically modified variety and the total supply of the variety is provided. Second, it is shown that when products can be falsely labeled as non-genetically modified, the share of false labeling depends on the level of identity preservation. Also in this context, it is demonstrated that the share of falsely labeled supply can increase in response to harsher fines.Agribusiness,

Middlemen behaviour and generic advertising rents in competitive interrelated industries

This article focuses on the role of middlemen in determining the returns to generic advertising in a competitive industry where supply is uncontrolled, the price of marketing inputs is endogenous, and retail markets are interrelated through consumer preferences. Theoretical analysis suggests farm-gate returns (quasi-rents) are overstated when input substitution at middlemen level is ignored, a result confrmed in the empirical application. As for mark-up behaviour, represented by the farm-retail price transmission elasticity, a general result is that farm-gate returns to generic advertising always increase as the transmission elasticity decreases, provided retail demand is more elastic than input substitution. Endogenising the price of marketing inputs has little effect on advertising rents.Agribusiness, Marketing,

The Value of Network Information

The business model of companies such as Facebook, MySpace, and Twitter, relies on monetizing the information on the interactions and influences of their users. How valuable is such information, and is its use beneficial or detrimental for consumer welfare? We study these questions in a model where a monopoly sells a network good and may price discriminate using network information: information on consumers influences and/or on consumers susceptibilities to influence. Our framework incorporates a rich set of market products, including goods characterized by global and local network effects. We derive results on the value of network information and determine under which conditions, relative to uniform price, consumer surplus increases. We demonstrate the applicability of our framework using survey data on various types of relationships

Eco-Labels for Credence Attributes: The Case of Shade-Grown Coffee

Using the case of shade-grown coffee, this paper examines the market impacts of eco-labels for credence attributes. First, the Mattoo and Singh (1994) test is conducted for the case of shade-grown coffee to investigate the market impacts of a shade label. This analysis in Section II shows that a shade label could pass the test, but the market impacts are likely to be minor. Section II also shows how to use estimates of supply, potential demand, and price elasticities of demand and supply to predict eco-label premiums in the post-label equilibrium. And second, given the importance of consumer demands for eco-label impacts, and since the theoretical foundations of demand for eco-labeled items are not well developed in the literature, Section III takes a closer look at the microeconomics of labels and consumer demand. A nested constant-elasticity-of-substitution preference structure is used to derive theoretically consistent Marshallian demands for shade and non-shade coffee. A numerical simulation shows how relative prices and consumer preferences for the credence attribute and variety are both important factors in demand creation of labeled items.Environmental Economics and Policy, Marketing,

Exploring Linkages Among Agriculture, Trade, and the Environment: Issues for the Next Century

Many trade and environment issues will confront agriculture over the next several years. This report provides an economic framework to better understand these issues and discusses prior empirical inquiries and findings. Four primary issues are addressed: (1) how will environmental policies affect agricultural trade?; (2) how will agricultural trade liberalization affect environmental quality?; (3) to what extent should there be international harmonization of environmental policies and product standards?; and (4) is there economic justification for using trade measures to protect the environment? This report demonstrates that basic economic paradigms can provide a basis for understanding how trade and the environment interact. The few empirical studies based on these concepts have found many of the linkages between trade and the environment to be weak or the effects small. Trade and environment issues remain important to monitor, however, because economic and environmental relationships and domestic and international policies are continually evolving, and decision-makers need good information to confirm or disprove the numerous hypotheses that have surfaced in international discussions.environmental policy, agricultural policy, trade policy, trade, environment, harmonization, Agricultural and Food Policy, Environmental Economics and Policy, International Relations/Trade,

Comparative Analysis of Organizational Forms in the Software Industry and Legal Services

Law firms are expected to be controlled by the workers because given the difficulty of monitoring labor, the transaction cost would be very high and the essential human capital investment would be lacking in a form controlled by the capital suppliers. Expectations are confirmed by the data. However, following the same reasoning one can easily suggest that software firms should also be controlled by the labor suppliers given the similar difficulty of monitoring labor and essential human capital. As in a law firm, the software firm uses very generic capital such as offices, computers and programming languages. Moreover, the human capital of the software developer is indispensable and highly firm specific. While we observe widespread worker control in terms of partnerships in legal service industry, the majority of the software firms are not controlled by the labor suppliers: instead they are controlled by the capital suppliers.Organizational forms, Asset specificity

Does History Matter Only When it Matters Little? The Case of City-Indu try Location

When will an industry subject to agglomeration economies move from an old, high-cost site to a new, low-cost site? It is argued that history, in the form of sunk costs resulting from the operation of many firms at a site, creates a first-mover disadvantage that can prevent relocation. It is demonstrated that developers of industrial parks can partly overcome this inertia through discriminatory pricing of land over time, and empirical evidence is provided that they actually engage in such behavior. It is also shown that other aspects of developer land-sale strategy can be a source of information on the nature of interfirm externalities.
