On the Unequal Inequality of Poor Communities

Communities differ in important ways in their needs, capacities,and circumstances. Because central governments are not ableto discern these differences fully, they seek to achieve theirpolicy objectives by relying on decentralized mechanisms thatuse local information. Household and individual characteristicswithin communities can also vary substantially. A growing bodyof theoretical literature suggests that inequality within communitiescan influence policy outcomes in ways that are either harmfulor helpful, depending on the circumstances. Until recently,empirical investigations into the impact of inequality havebeen held back by a lack of systematic evidence on community-levelinequality. This study uses household survey and populationcensus data to estimate per capita consumption inequality withincommunities in three developing economies. It finds that communitiesvary markedly in their degree of inequality. It also shows thatthere should be no presumption that inequality is less severein poor communities. The kind of community-level inequalityestimates generated here can be used in designing and evaluatingdecentralized antipoverty programs.     

Small-Scale Industry, Environmental Regulation, and Poverty: The Case of Brazil

Governments and international development agencies have intensifiedefforts to promote small-scale enterprises as an engine of propoorgrowth. In Brazil, however, small-scale industries may alsobe responsible for the bulk of air pollution emissions. Althoughemployees of polluting small-scale industries in Brazil arenot disproportionately poor, simulations suggest that stringentenvironmental regulation resulting in widespread closures ofpollution-intensive small-scale industries would result in anonnegligible increase in poverty among employees of these firms.The results suggest that the enthusiasm for small-scale enterprisesneeds to be tempered by awareness of the potential environmentalcosts imposed by this sector.     

Regulated Efficiency, World Trade Organization Accession, and the Motor Vehicle Sector in China

This article is concerned with the interaction of regulatedefficiency and World Trade Organization (WTO) accession andits impact on China's motor vehicle sector. The analysis isconducted using a 23 sector–25 region computable generalequilibrium model. Regulatory reform and internal restructuringare found to be critical. Restructuring is represented by acost reduction following from consolidation and rationalizationthat moves costs toward global norms. Without restructuring,WTO accession means a surge of final imports, though importsof parts could well fall as production moves offshore. However,with restructuring, the final assembly industry can be madecompetitive by world standards, with a strengthened positionfor the industry.     

Selling to the moneyed masses

Over the past decade, the distribution of household incomes has shifted so much that a much larger proportion of consumers now earn significantly higher-than-average incomes--while still falling short of being truly rich. As a result, what used to be a no-man's-land for new product introductions has in many categories become an extremely profitable "new middle ground." How can marketers capitalize on this new territory? The key, say the authors, is to rethink the positioning and design of offerings and the ways they can be brought to market. Take, for instance, how Procter & Gamble redefined the positioning map for tooth-whitening solutions. A decade ago, dental centers were popularizing expensive bleaching techniques that put the price of a professionally brightened smile in the 400 dollars range. At the low end, consumers also had the choice of whitening toothpastes that cost anywhere from 2 dollars to 8 dollars. P&G wisely positioned itself between the two ends, successfully targeting the new mass market with its 35 dollars Whitestrips. In product categories where it's clear the middle ground has already been populated, it's important for companies to design or redesign offerings to compete. An example is the Polo shirt. How do you sell a man yet another one after he's bought every color he wants? Add some features, and call it a golf shirt. Here, marketers have introduced designs based on the concept of "occasional use" in order to stand out. Finally, companies wishing to reach the "almost rich" can change how they go to market. Perhaps no mass retailer has made a stronger bid for the mass affluent than Target Stores, which has pioneered a focus the company itself characterizes as upscale discount. The strategy has made Target an everyday shopping phenomenon among well-heeled urbanites and prosperous professionals.     

Trust and economic growth: a robustness analysis

This paper analyses the robustness of results on the relationshipbetween growth and trust previously derived by Knack and Keefer(1997) and Zak and Knack (2001) along several dimensions, acknowledgingthe complexity of the concept of robustness. Our results showthat the Knack and Keefer results are only limitedly robust,whereas the results found by Zak and Knack are highly robustin terms of significance of the estimated coefficients and reasonablyrobust in terms of the estimated effect size. The improvementin robustness is caused by the inclusion of countries with relativelylow scores on trust (most notably, the Philippines and Peru).Overall, our results point at a relatively important role fortrust. However, the answer to the question how large this payoffactually is depends on the set of conditioning variables controlledfor in the regression analysis and—to an even larger extent—onthe underlying sample.     

Revealed preferences in macroeconomic policy decisions

This paper extends the usual instrument-target framework by directly estimating macroeconomic policy preferences over a number of policy targets using a derived reduced form and then solving the nonlinear optimality conditions for optimal instrument choice. Solving the optimality equations using observations on predetermined variables yields the implicit set of preference weights which induced the observed choices. The derivation format parallels the integrability discussions about consumer preferences implicitly expressed through demand functions. The approach is applied to a simple macro model estimated over the period from 1955 through 1972.     

Über die Verteilung von Produktionszeiten in Assemblage-Prozessen

Zusammenfassung Es werden Produktionszeiten in Assemblage-Systemen behandelt;p parallele Produktionslinien erzeugen Teilstücke, die zu Gruppen vonp Stücken, je eines aus einer Linie, zusammengestellt werden. Als Produktionszeit wird die Zeit zwischen zwei aufeinanderfolgenden Gruppenoutputs definiert. Aus der Verteilung der Produktionszeiten an den einzelnen Linien wird die Grenzverteilung der Produktionszeiten hergeleitet. Dabei zeigt sich, da? diese Grenzverteilung im wesentlichen von den Wahrscheinlichkeiten abh?ngt, da? bestimmte Produktionslinien zurückbleiben und dadurch den Produktionstakt der Gruppen bestimmen. Sind — das ist der interessanteste Fall — die Mittelwerte der Produktionszeiten an den einzelnen Linien gleich, so sind diese Wahrscheinlichkeiten als Funktionen der Varianzen der Produktionszeiten darstellbar; sie lassen sich darüber hinaus als Volumina gewisser nichteuklidischer Simplexe in sph?rischen R?umen mit konstanter Krümmung deuten.

Summary Production times in assemblage-systems are considered;p parallel production lines produce pieces, which are combined to groups ofp pieces, each from another line. Production time is defined as the time between two consecutive outputs of such groups. Given the production time of the individual lines, the limiting distribution of the group production times will be derived. This limiting distributions are essentially dependent on the probabilities that a specified line will lag behind all others and so will determine the production time of the groups. If the means of production times of the single lines are equal — this will be the most interesting case — then these probabilities can be expressed as functions of the variances of the production time of the single pieces. They also can be interpreted as volumes of certain non-euclidean simplices in spherical spaces of constant curvature.
