Necessarily welfare-enhancing customs unions with industrialization constraints: The Cooper-Massell-Johnson-Bhagwati conjecture

This paper demonstrates that welfare-improving Customs Unions can be guaranteed even if we are constrained by specific non-economic government objectives, thus proving the Cooper-Massell-Johnson-Bhagwati conjecture. We consider a ‘production’ objective here, where a member country requires the output of a particular sector (e.g. a target level of industrialization) to be maintained at the pre-union level, and show that welfare-improving Customs Unions can still be achieved. It is straightforward to show that this result can be extended to other non-economic objectives as well.     

Estimating the stationary distribution of a Markov chain

Summary. Let be a Markov chain with a unique stationary distribution . Let h be a bounded measurable function. Write and . This paper explores conditions for the consistency and asymptotic normality of the estimate of of assuming the existence of a solution to the Poisson equation . Our framework covers the case of nonirreducible Markov chains arising in many growth models in economics.

Analyst Specialization and Conglomerate Stock Breakups

This paper examines whether firms emerging from conglomerate stock breakups are able to affect the types of financial analysts that cover their firms as well as the quality of information generated about their performance. Our sample comprises 103 focus-increasing spin-offs, equity carve-outs, and targeted stock offerings between 1990 and 1995. We find that, after these transactions, sample firms experience a significant increase in coverage by analysts that specialize in subsidiary firms' industries, and a 30–50% increase in analyst forecast accuracy for parent and subsidiary firms. The improvement in forecast accuracy is partially attributable to expanded disclosure. However, forecast improvements for specialists exceed those for non-specialists, leading us to conclude that corporate focus can facilitate improved capital market intermediation by financial analysts with industry expertise.     

Estimating the effects of higher coupon face values on the timing of redemptions,the mix of coupon redeemers,and purchase quantity

One of the key decisions a manager must make in designing a coupon promotion is to decide on the face value. In this study we examine the effects of higher face values on coupon redemption timing, category purchase timing, the mix of buyers who redeem the coupon, and purchase quantity. Data from a field experiment on coupon face values are used to test the hypotheses. A new method of measuring the effects of a coupon on category purchase timing is proposed. We find that coupons per se tend to advance category purchase timing, but higher face values do not increase the magnitude of this effect. Surprisingly, higher face values appear to increase redemption rates for both the prior nonbuyers and prior buyers of the brand in a similar way. However, higher face values have little effect on the package size purchased, the number of units purchased, or the total quantity (package size times units) purchased.     

Customer value,satisfaction, loyalty,and switching costs: An illustration from a business-to-business service context

Although researchers and managers pay increasing attention to customer value, satisfaction, loyalty, and switching costs, not much is known about their interrelationships. Prior research has examined the relationships within subsets of these constructs, mainly in the business-to-consumer (B2C) environment. The authors extend prior research by developing a conceptual framework linking all of these constructs in a business-to-business (B2B) service setting. On the basis of the cognition-affect-behavior model, the authors hypothesize that customer satisfaction mediates the relationship between customer value and customer loyalty, and that customer satisfaction and loyalty have significant reciprocal effects on each other. Furthermore, the potential interaction effect of satisfaction and switching costs, and the quadratic effect of satisfaction, on loyalty are explored. The authors test the hypotheses on data obtained from a courier service provider in a B2B context. The results support most of the hypotheses and, in particular, confirm the mediating role of customer satisfaction.

Allocating multiple units

Summary. This paper studies the allocation and rent distribution in multi-unit, combinatorial-bid auctions under complete information. We focus on the natural multi-unit analogue of the first-price auction, where buyers bid total payments, pay their bids, and where the seller allocates goods to maximize his revenue. While there are many equilibria in this auction, only efficient equilibria remain when the truthful equilibrium restriction of the menu-auction literature is used. Focusing on these equilibria we first show that the first-price auction just described is revenue and outcome equivalent to a Vickrey auction, which is the multi unit analogue of a second-price auction. Furthermore, we characterize these equilibria when valuations take a number of different forms: diminishing marginal valuations, increasing average valuations, and marginal valuations with single turning points.
