    Violating purchasing power parity.

    This paper demonstrates that deviations from the law of one price are an important source of violations of absolute PPP across countries. Using highly disaggregated U.S. export data, we document evidence of systematic international price discrimination based on the local wage of consumers in the destination market. We show that most violations from absolute PPP can also be explained by international differences in wages. We find very little additional explanation is due to differences in income per capita. Developing and calibrating a model of pricing-to-market based on search frictions and international productivity differences, we show that pricing-to-market accounts for 62 percent of the relationship between national price levels and income and 100 percent of the deviation from the law of one price. In contrast, the textbook Harrod-Balassa-Samuelson effect accounts for the remaining 38 percent of the relationship between national price levels and income.Purchasing power parity

    The Economics of Duty-Free Shopping

    Get PDF
    In 1999 the EU abolished duty-free on intra-EU travel, whilst other countries still retain duty-free shopping for international travellers. We address several aspects of duty-free trade, including effects on consumption, revenue and price-setting. From a global perspective we identify the distortions generated by duty-free trade. We review, and dismiss, various arguments that might conceivably support a role for duty-free in promoting global economic welfare. The existence of duty-free trade is explained as a phenomenon that individual countries find in their national self interest as seen both from the arrival and the departure end, i.e. countries have reasons both to admit duty-free goods and to permit their sale to departing passengers.

    A General Equilibrium Financial Asset Economy with Transaction Costs and Trading Constraints

    Get PDF
    This paper presents a unified framework for examining the general equilibrium effects of transactions costs and trading constraints on security market trades and prices. The model uses a discrete time/state framework and Kuhn-Tucker theory to characterize the optimal decisions of consumers and financial intermediaries. Transaction costs and constraints give rise to regions of no trade and to bid-ask spreads: their existence frustrate the derivation of standard results in arbitrage-based pricing. Nevertheless, we are able to obtain as dual characterizations of our primal problems, one-sided arbitrage pricing results and a personalized martingale representation of asset pricing. These pricing results are identical to those derived by Jouini and Kallal (1995) using arbitrage arguments. The paper's framework incorporates a number of specialized existing models and results, proves new results and discusses new directions for research. In particular, we include characterizations of intermediaries who hold optimal portfolios; brokers who do not hold portfolios, and consumer-specific transactions costs and trading constraints. Furthermore we show that in the special case of equiproportional transaction costs and a sufficient number of assets, there is an analogue of the arbitrage pricing result for European derivatives where prices are interpreted as mid-prices between the bid-ask spread. We discuss the effects of non-convex transaction technologies on prices and trades.Financial Markets, Transaction Costs, Trading Constraints, Asset Pricing, General Equilibrium, Incomplete Markets

    The performance of Bulgarian food markets during reform

    Get PDF
    Food policy often depends on markets and markets depend on institutions. But how good do institutions have to be before reforms can be launched? Relying on well timed surveys of agricultural prices and a joint study by the Government of Bulgaria and the World Bank on agricultural market institutions, this paper presents evidence that performance in food markets improved following significant policy reforms in Bulgaria, although public institutions remained weak. This suggests that even though strong institutions are preferred to weak ones, it can be costly and impractical to delay policy reforms until work on strengthening institutions is finished. Still, measured performance varied by place and by commodity, suggesting that markets developed at different tempos and that the distribution of benefits from improved markets was uneven. This points to the need to address the costs of adjustment as policies change. The paper introduces a new approach to measure market performance based on composite-error techniques.Markets and Market Access,Transport Economics Policy&Planning,Economic Theory&Research,Access to Markets,Agribusiness

    Pricing-to-market and the failure of absolute PPP

    Get PDF
    The authors show that deviations from the law of one price in tradable goods are an important source of violations of absolute PPP across countries. Using highly disaggregated export data, they document systematic international price discrimination: at the U.S. dock, U.S. exporters ship the same good to low-income countries at lower prices. This pricing-to-market is about twice as important as any local non-traded inputs, such as distribution costs, in explaining the differences in tradable prices across countries. The authors propose a model of consumer search that generates pricing-to-market. In this model, consumers in low-income countries have a comparative advantage in producing non-traded, non-market search activities and therefore are more price sensitive than consumers in high-income countries. They present cross-country time use evidence and evidence from U.S. export prices that are consistent with the model.

    Customs Valuation in India: Identifying Trade Facilitation related Concerns

    Get PDF
    India has introduced several trade facilitation related measures in the last couple of years. The pro-active strategy adopted by the Central Board of Excise and Customs (CBEC) has helped in introducing several policy measures which have not only streamlined the role of the customs department but has also helped industry in a major way without compromising collection of revenue.Trade Facilitation, Customs Valuation, India

    Does it pay to invest in art? A selection-corrected returns perspective : [draft october 15, 2013]

    Get PDF
    This paper shows the importance of correcting for sample selection when investing in illiquid assets with endogenous trading. Using a large sample of 20,538 paintings that were sold repeatedly at auction between 1972 and 2010, we find that paintings with higher price appreciation are more likely to trade. This strongly biases estimates of returns. The selection-corrected average annual index return is 6.5 percent, down from 10 percent for traditional uncorrected repeat sales regressions, and Sharpe Ratios drop from 0.24 to 0.04. From a pure financial perspective, passive index investing in paintings is not a viable investment strategy once selection bias is accounted for. Our results have important implications for other illiquid asset classes that trade endogenously

    Why the Law Hates Speculators: Regulation and Private Ordering in the Market for OTC Derivatives

    Get PDF
    A wide variety of statutory and common law doctrines in American law evidence hostility towards speculation. Conventional economic theory, however, generally views speculation as an efficient form of trading that shifts risk to those who can bear it most easily and improves the accuracy of market prices. This Article reconciles the apparent conflict between legal tradition and economic theory by explaining why some forms of speculative trading may be inefficient. It presents a heterogeneous expectations model of speculative trading that offers important insights into antispeculation laws in general, and the ongoing debate concerning over-the-counter (OTC) derivatives in particular. Although trading in OTC derivatives is presently largely unregulated, the Commodity Futures Trading Commission recently announced its intention to consider substantively regulating OTC derivatives under the Commodity Exchange Act (CEA). Because the CEA is at heart an antispeculation law, the heterogeneous expectations model of speculation offers policy support for the CFTC\u27s claim of regulatory jurisdiction. This model also, however, suggests an alternative to the apparently binary choice now available to lawmakers (i. e., either regulate OTC derivatives under the CEA, or exempt them). That alternative would be to regulate OTC derivatives in the same manner that the common law traditionally regulated speculative contracts: as permitted, but legally unenforceable, agreements. By requiring derivatives traders to rely on private ordering to ensure the performance of their agreements, this strategy may offer significant advantages in discouraging welfare-reducing speculation based on heterogeneous expectations while protecting more beneficial forms of derivatives trading
