A Measure of Stock Market Integration for Developed and Emerging Markets

A wide array of official capital controls across countries makesit difficult to perform cross-sectional analysis of the effectsof market segmentation. This article constructs a measure ofdeviations from capital market integration that can be consistentlyapplied across countries. It measures the deviations of assetreturns from an equilibrium model of returns constructed assumingmarket integration. Applying the measure to stock returns fromtwenty-four national markets indicates that market segmentationtends to be much larger for emerging markets than for developedmarkets, and that the measure tends to decrease over time. Alongseveral dimensions, the proposed measure yields results thatare consistent with reasonable priors about the relations betweeneffective integration and explicit capital controls, capitalmarket development, and economic growth.     

Changing Agricultural Markets: Industrialization and Vertical Coordination in the Dry Edible Bean Industry

The agricultural sector is undergoing a transformation that is altering marketing relationships to better serve customer needs. These changes are drawing consumers, processors, and farmers into closer marketing relationships, improving the flow of information up the supply chain, and enabling firms to better meet customer demand. This paper uses case studies to analyze this process as it is occurring in the dry edible bean industry. A major finding is that contracts are not necessarily used in these new marketing relationships. Other factors—such as quality monitoring, certification procedures, and reputation—were also found to be highly important.     

ESTIMATING THE VALUE OF DELIVERY OPTIONS IN FUTURES CONTRACTS

We analyze the effect various delivery options embedded in commodity futures contracts have on the futures price. The two embedded options considered are the timing and location options. We show that early delivery is always optimal when only a timing option is present, but not so when joint options are present. The estimates of the combined options are much smaller than the comparable estimates for the timing option alone. The average value of the joint option is about 5% of the average basis on the first day of the maturity month. This suggests that joint options can increase deliverable supplies while potentially having only a small effect on basis behavior.     

UNITS OF DEBT WITH WARRANTS: EVIDENCE OF THE “PENALTY-FREE” ISSUANCE OF AN EQUITY-LIKE SECURITY

While units of debt with warrants are not structured as perfect substitutes for convertible bonds, there is reason to believe that firms view the two securities as viable alternative methods of raising funds. Analyses of the capital market effects of the announcement of the plan to issue and the issuance of units of debt with warrants provide unique evidence of the “penalty-free” issuance of an equity-like security. Evidence is found to support the conjecture that units are typically issued by smaller, riskier firms than are convertible bonds. However, there is no evidence that the use of this security is interpreted by the market as a sign of financial distress.     

Sources of Durable Competitive Advantage in New Products

In this article, Michael Lawless and Robert Fisher propose a conceptual framework for analyzing durable sources of competitive advantage for new products. They assess various components of new product introduction strategies in terms of their degrees of competitive "imitability" (i.e., the ease with which competitors can imitate). The less imitable the component, the more durable the profits it generates. The authors identify seven strategic components based on bodies of research in strategy and promotion, distribution and firm characteristics. By selectively managing these components, an innovating firm can affect a new product's imitability and the duration of returns. Using a "resource mobility" perspective, the authors develop propositions that should lead to a more systematic focus on long-term profits in new product introductions.
