    This paper constitutes an attempt to reframe and eventually deflate the ongoing “compliance-vs.-rebalancing” debate which has permeated WTO scholarship for the last 10 years. At face value, this controversy circles around object and purpose of WTO enforcement and the legal nature of dispute panels’ recommendations: Compliance advocates maintain that the objective of WTO enforcement is to induce compliance with DSB panel/AB rulings, and to deter future violations of the Agreement, while rebalancing advocates detect an inherent “pay-or-perform” logic in WTO enforcement. In the paper we examine the shortcomings of each approach separately. Our main criticism, however, concerns the substance of the entire debate. We find that scholars on both sides of the compliance/rebalancing controversy put an unduly rigid emphasis on the subsequent issues of WTO enforcement and the interpretation of the wording of the dispute settlement understanding. They thereby neglected systemic issues of contracting, viz. the nature of contractual entitlements, the need for trade policy flexibility mechanisms and the optimal design of the appropriate remedies. We redefine and recalibrate the compliance/rebalancing controversy along the lines of the nature of the WTO contract. This results in to three key findings: First, none of the two schools of thought succeeds in giving an accurate picture of the WTO treaty. Second, the two perspectives actually portray two strikingly different concepts of the WTO contract, and therefore have been at cross-purposes from the very beginning. This implies a third finding: The two schools of thought essentially describe different facets of the same complex WTO contract. Hence, they have hardly been at loggerheads at all, and are actually complementing each other in important aspects. We lay out a unified research agenda that practitioners, economists, trade lawyers, and international relations scholars alike can accept. The agenda may contribute to reconciling the two opposing views and help WTO scholarship tackle the real systemic issues of the WTO Agreement.WTO, dispute settlement, incomplete contracts, remedies, enforcement

    The Optimal Design of Trade Policy Flexibility in the WTO

    Get PDF
    This paper is a contribution to the literature on rational design of trade agreements. The World Trade Organization (WTO) is an incomplete contract among sovereign states. Incomplete contracts contain gaps. Ex post, contractual gaps may leave gains from trade unrealized; they may create “regret” in signatories once unanticipated contingencies or sudden protectionist backlashes have occurred. Trade policy flexibility mechanisms, such as the “safeguards clause” under Art. XIX GATT, are geared towards seizing ex post regret by allowing parties affected by a protectionist shock to partially and temporarily withdraw from previously made trade liberalization concessions – given that they compensate the victim(s) of such backtracking behavior. This paper examines the somewhat understudied issue of optimal trade policy flexibility design in the WTO: In particular, we analyze whether ex post escape should be organized by means of a unilateral opt-out clause (a “liability rule” of escape), or a bilateral renegotiation provision (a “property rule” of escape). Modeling the WTO as a fully non-contingent tariff liberalization contract with contingencies (or “states of nature”) asymmetrically revealed, we find that a liability rule backed by expectation remedies payable to the affected victim Pareto-dominates both a renegotiation clause, as well as any other remedy arrangement connected to a liability rule. Only the remedial design of liability-cum-expectation damages yields the desirable incentives to liberalize ex ante, and to default ex post and therewith is able to replicate the outcomes of the hypothetical contracting ideal of the complete contingent contract.Incomplete contracts, remedies, enforcement, WTO, trade renegotiations, WTO Dispute Settlement,

    Photoselective Metal Deposition on Amorphous Silicon p-i-n Solar Cells\ud

    Get PDF
    A novel method is described for the patternwise metallization of amorphous silicon solar cells, based on photocathodic deposition. The electric field of the p-i-n structure is used for the separation of photogenerated charge carriers. The electrons are driven to the interface of the n+-layer with the solution where they reduce metal ions to metal. The large difference between the conductivity of dark and illuminated areas and the high sheet resistance of the n-type layer makes it possible to define a metal pattern by selective illumination. It is shown that both nickel and gold patterns can be deposited using this method. After annealing, an ohmic nickel contact is formed and the cell exhibits good photovoltaic characteristics

    Indisputably essential: The economics of dispute settlement institutions in trade agreements

    Full text link
    Economic theory has made considerable progress in explaining why sovereign countries cooperate in trade. Central to most theories of trade cooperation are issues of self-enforcement: The threat of reprisal by an aggrieved party maintains the initial balance of concessions and prevents opportunism. However, economic scholarship has been less coherent in explaining why countries choose to settle and enforce their trade disputes with the help of an impartial third party, a “trade court”. Typically, economists focusing on the purpose of trade agreements have assumed away the very reasons why institutions are needed, since under standard assumptions, neither defection from the rules nor disputes are expected to occur. This paper is a step towards the formulation of a coherent economic theory of dispute settlement. It challenges traditional models of enforcement (primarily concerned with acts of punishment) for being insufficient in explaining the existence of dispute settlement institutions. We perform a comprehensive analysis of the economics of dispute settlement institutions and demonstrate to what extent the literatures of trade cooperation and dispute institutions are (and should be) interlinked. On the basis of these theories, we show that dispute settlement institutions in trade agreements may assume a variety of roles, including that of an information repository and disseminator, an honest broker, an arbitrator and calculator of damages, an active information gatherer or an adjudicator

    Transport in tunnelling recombination junctions: a combined computer simulation study

    Get PDF
    The implementation of trap-assisted tunneling of charge carriers into numerical simulators ASPIN and D-AMPS is briefly described. Important modeling details are highlighted and compared. In spite of the considerable differences in both approaches, the problems encountered and their solutions are surprisingly similar. Simulation results obtained for several tunneling recombination junctions made of amorphous silicon (a-Si), amorphous silicon carbide (a-SiC), or microcrystalline silicon (µc-Si) are analyzed. Identical conclusions can be drawn using either of the simulators. Realistic performances of a-Si/a-Si tandem solar cells can be reproduced with simulation programs by assuming that extended-state mobility increases exponentially with the electric field. The same field-enhanced mobilities are needed in single tunneling recombination junctions in order to achieve measured current levels. Temperature dependence of the current-voltage characteristics indicates that the activation energy of enhanced mobilities should be determined. Apparent discrepancies between simulation results and measurements are explained and eliminated making use of Gill’s law. For application in tandem and triple solar cell structures, tunneling recombination junctions made of (µc-Si) are the most promising of all examined structures.Fil: Vukadinovic, M..

    Nonfree datatypes in Isabelle/HOL: animating a many-sorted metatheory

    Get PDF
    Datatypes freely generated by their constructors are well supported in mainstream proof assistants. Algebraic specification languages offer more expressive datatypes on axiomatic means: nonfree datatypes generated from constructors modulo equations. We have implemented an Isabelle/HOL package for nonfree datatypes, without compromising foundations. The use of the package, and its nonfree iterator in particular, is illustrated with examples: bags, polynomials and λ-terms modulo α-equivalence. The many-sorted metatheory of nonfree datatypes is formalized as an ordinary Isabelle theory and is animated by the package into user-specified instances. HOL lacks a type of types, so we employ an ad hoc construction of a universe embedding the relevant parameter types

    Systematic risk of CDOs and CDO arbitrage

    Get PDF
    “Arbitrage CDOs” have recorded an explosive growth during the years before the outbreak of the financial crisis. In the present paper we discuss potential sources of such arbitrage opportunities, in particular arbitrage gains due to mispricing. For this purpose we examine the risk profiles of Collateralized Debt Obligations (CDOs) in some detail. The analyses reveal significant differences in the risk profile between CDO tranches and corporate bonds, in particular concerning the considerably increased sensitivity to systematic risks. This has farreaching consequences for risk management, pricing and regulatory capital requirements. A simple analytical valuation model based on the CAPM and the single-factor Merton model is used in order to keep the model framework simple. Then, the conditional expected loss curve (EL profile) is studied in some detail. In the next step, the asset correlation associated with a CDO tranche is estimated treating the structured instrument as a single-name credit instrument (i.e., a loan equivalent). While tractable, the loan-equivalent approach requires appropriate parameterization to achieve a reasonable approximation of the tranche´s risk profile. We consider the tranche as a “virtual” borrower or bond for which a single-factor model holds. Then, the correlation parameter is calculated via a non-linear optimization. This “bond representation” allows to approximate the risk profile (expressed by the EL profile) using a single-factor model and to express the dependence on the systematic risk factor via the corresponding asset correlation. It turns out that the resulting asset correlation is many times higher than that of straight bonds. Then, the Merton type valuation model for the corresponding bond representations is applied for valuation of the CDO tranches. Using a sample CDO portfolio, some opportunities for “CDO arbitrage” are described where it is assumed that investors are guided solely by the tranches’ rating and ignore the increased systematic risk for pricing. In the next section we discuss how tranches with high systematic risk can be generated and how CDO arrangers can exploit this to their advantage. It comes as no surprise that precisely these types of structures featured in many of the CDOs issued prior to the outbreak of the financial crisis. --Collateralized debt obligations (CDO),arbitrage CDOs,credit rating,expected loss profile,bond representation,systematic risk of CDO tranches,CDO pricing

    Optimisation of doped microcrystalline silicon films deposited at very low temperatures by Hot-Wire CVD

    Get PDF
    In this paper we present new results on doped μc-Si:H thin films deposited by hot-wire chemical vapour deposition (HWCVD) in the very low temperature range (125-275°C). The doped layers were obtained by the addition of diborane or phosphine in the gas phase during deposition. The incorporation of boron and phosphorus in the films and their influence on the crystalline fraction are studied by secondary ion mass spectrometry and Raman spectroscopy, respectively. Good electrical transport properties were obtained in this deposition regime, with best dark conductivities of 2.6 and 9.8 S cm -1 for the p- and n-doped films, respectively. The effect of the hydrogen dilution and the layer thickness on the electrical properties are also studied. Some technological conclusions referred to cross contamination could be deduced from the nominally undoped samples obtained in the same chamber after p- and n-type heavily doped layers

    Rice Age: Comments on the Panel Report in Turkey - Measures Affecting the Importation of Rice

    Get PDF
    At face value, Turkey-Rice is not the most complex or important WTO dispute ever litigated. The facts of the case give strong reason to believe that Turkey's restrictions on rice imports from the United States were not GATT-consistent. Turkey's steadfast refusal to provide exonerating evidence in its defence and the Panel's drawing of appropriate inference were probably the most remarkable issues of the case. Nevertheless, Turkey-Rice raises at least one interesting legal and economic question: How ‘activist' are dispute panels today, and how interventionist should they be during the litigation process? We discuss the justification and role of activist panels and assess the consequences for parties' strategic behavior and incentive to provide accurate informatio
