Evidence on agglomeration economies,diseconomies, and growth

Conventional urban economic analysis suggests that a local economy's size is closely related to a number of features, including levels of human capital and the availability of specialized inputs, which are likely to influence positively the rate at which it accumulates further economic activity. At the same time, urban theory also suggests that once cities reach a certain level of size, these agglomeration benefits begin to peter out, while diseconomies rise rapidly. Consequently, we should see an ‘inverted U‐shaped’ pattern of growth with respect to economic size—rates of growth first rise, then fall as size increases. This paper shows that, while such a pattern is largely absent from recent data on growth in metropolitan area population and employment, it emerges strikingly in county‐level data.

Socio‐economic factors determining the success achieved among cotton‐adopting households in two magisterial districts of KwaZulu

The aim of the paper is to investigate certain aspects of the post‐adoption behaviour of dryland cotton farmers in the Ubombo and Hlabisa magisterial districts of KwaZulu. Particular attention is paid to the socio‐economic determinants of the success (returns per hectare) of the household cotton enterprise.

Multi‐stage sampling methods were used to draw a random sample of fifty cotton‐farming households from each of the two study districts. The data were collected by interview survey and analysed using principal components and regression techniques.

Results suggest that the success of the household enterprise in both areas is largely determined by the socio‐economic environment under which the producer operates. The most important success‐determining factors are those relating to the human capital endowments and economic status of the household.     

Formal and Informal Regulation of Industrial Pollution: Comparative Evidence from Indonesia and the United States

Economic theory and recent empirical work suggest that whenformal regulation of pollution is absent or less than 100 percenteffective, affected communities are often able to negotiateabatement from plants in their vicinity through "informal regulation."Using a model of equilibrium pollution, this article confirmsthe existence of significant informal regulation for unregulatedpollutants in both Indonesia and the United States as well asfor regulated pollutants in the United States. Combining plant-leveldata with community data in both countries, regressions revealthat even after controlling for traditional economic variablessuch as output levels and input prices as well as for plantcharacteristics such as industrial sector and age, the per capitaincome of affected communities significantly affects pollutionintensities. Higher-income communities win significantly loweremissions in both countries and for both unregulated and regulatedpollutants in the United States, presumably because income affectsboth preferences for environmental quality and the ability tobring pressure on polluting factories.     

Price elasticity of water allocations demand in the Goulburn–Murray Irrigation District*

Bid prices for the demand and supply of water allocations between 2001 and 2007, and average monthly prices paid for water allocations from 1997 to 2007 in the Goulburn–Murray Irrigation District are analysed to estimate price elasticities. Based on bid prices, the price elasticity of demand for water allocations appears highly elastic, with elasticities strongly influenced by the season and drought. The price elasticity of supply for water allocations is also elastic, albeit less elastic than demand. Using actual prices paid, water demand is negatively related to price and is inelastic, and appears to be most influenced by demand the previous month, drought and seasonality factors.     

Strategy analysis in the health service

The operation of provider units, both NHS Trusts and Directly Managed Units, as competitive organizations in the market place, is as yet rudimentary. Although some have achieved notoriety through radical “business” behaviour, there is little evidence that they have adopted scientific business practices in order to strengthen or re‐orientate their position in the market place. Neither is there as yet any hard evidence that such behaviour would be beneficial in the long term.

This paper describes an exercise of strategic market analysis used as a device to lead and inform the business planning process for an NHS Trust. The primary objective of the analysis is to identify hitherto unrecognized strategies which would enhance the position of the organization in the market place and also to identify areas where business development is possible and desirable.

The economic performance of cities: A Markov-switching approach

This paper examines the determinants of employment growth in metro areas. To obtain growth rates, we use a Markov-switching model that separates a city's growth path into two distinct phases (high and low), each with its own growth rate. The simple average growth rate over some period is, therefore, the weighted average of the high-phase and low-phase growth rates, with the weight being the frequency of the two phases. We estimate the effects of a variety of factors separately for the high-phase and low-phase growth rates. Growth in the high phase is related to both human capital and industry mix, while growth in the low phase is related to industry mix only, specifically, the relative importance of manufacturing. Overall, our results strongly reject the notion that city-level characteristics influence employment growth equally across the phases of the business cycle.     

A SUPPLY CHAIN MANAGER SELECTION METHODOLOGY: EMPIRICAL TEST AND SUGGESTED APPLICATION

With the expanding global economy, no managerial position requires a broader set of skills than that of the supply chain manager. Understanding the complexities of filling this vital managerial position, recent conceptual research has called for the development of a tool designed to identify the top candidates for supply chain positions. This research presents a full test of a three hurdle methodology for supply chain manager selection. Empirical results reported here suggest that managers must possess superior general mental aptitude, need for achievement, and adaptability for firms to maximize performance.
