International benchmarking has played a key role in the reform of Australia's infrastructure industries by promoting indirect or yardstick competition, in highlighting the need for further reform and building a consensus for implementing necessary changes. The international benchmarking of infrastructure performance by the Bureau of Industry Economics (BIE) between 1991 and 1996 did much to focus attention on the need for change. The BIE examined the performance of eight infrastructure industries relative to international best practice: electricity, rail freight, telecommunications, the waterfront, road freight, coastal shipping, aviation and gas supply. Performance comparisons concentrated on indicators of price, service quality, labour productivity and capital productivity. This paper reviews and summarises the performance comparisons the BIE undertook over the last three years of its infrastructure benchmarking program. The BIE international benchmarking program provides a useful role model for other countries wanting to seriously pursue reform of their infrastructure industries.  相似文献

The multiple objectives of perishable product inventory management are examined in this paper. These objectives include: (1) satisfying demand by carrying sufficient inventories, (2) holding down inventory carrying costs, (3) keeping the amount of product spoilage (outdating) at an acceptable level, and (4) maintaining quality by using the product while it is still fresh, and (5) keeping the cost of rotation low. Some of the above objectives are in conflict. Thus, certain redistribution policies may help attain one or more of these objectives to a greater extent. Redistribution involves the transfer of the product from outlets where demand is low to outlets where demand is high. A goal programming model for solving redistribution problems is presented. An example is provided and sensitivity analysis is performed in order to determine when redistribution is advantageous. Applicability of the model is discussed.  相似文献

Determinants of the stock price reaction to leveraged buyouts   总被引:1,自引:0,他引:1  
This paper investigates the determinants of leveraged buyout activity through the use of an abnormal return premium from the time of the first announcement through the final trading day. Consistent with the free. cash flow theory, firms with either high free cash flow or low Tobin’s q have higher abnormal returns. However, the returns to firms with both high free cash flow and low Tobin’s q are lower than firms with just one of these characteristics. Firms which substantially increase leverage and management buyouts with high insider ownership prior to the buyout have lower abnormal returns. Firms with lower risk, and therefore greater debt capacity, have higher abnormal returns.  相似文献

This paper developes a bioeconomic model to analyse the economic losses from the reduced harvesting of prey species resulting from an increase in the stock of a natural predator. Examples of large mammals creating economic damage are whales and African elephants. The economic losses depend critically on the actual management of the prey stock, although the three measures we develop are equal when the stock is managed so as to maximize the sustained economic rent from the prey species. Predation losses are illustrated by the case of the Northeastern Atlantic Minke whale, where the estimate of the average predation cost per whale in 1991–1992 is between $US 1780 and $US 2370, using Norwegian cost and earnings data. A ten percent stock increase is estimated to cause a loss of almost $US 19 million to the fishers of the prey species. If half of this cost were assigned to Norway it would be equivalent to 2.8 and 6.7 percent of the gross profits of the Norwegian cod and herring fisheries, respectively.  相似文献

Marginal areas of the world, including tropical highlands, tropical coastal zones, and arid lands, are problematical for development. They are ecologically special areas, often of vital consequence to the stability of more populated regions nearby. Commonly, their peoples are culturally distinct. To develop marginal areas it is suggested that “transformational” development may be appropriate. Transformational development recognizes the importance of equity and of working with existing resource systems already ecologically and culturally appropriate to the area. In marginal areas, a special application of transformational development could include incremental changes in existing systems and their connection to modern international systems so as to benefit the inhabitants of marginal areas and to supply commodities and goods demanded in the rest of the world. By rethinking ideas about resources, an exploratory framework for such transformation is examined. This framework uses the concept of “resource system”, a concept which might play an important part in the application of equitable future global development efforts.  相似文献

We develop optimal finite‐sample approximations for the band pass filter. These approximations include one‐sided filters that can be used in real time. Optimal approximations depend upon the details of the time series representation that generates the data. Fortunately, for U.S. macroeconomic data, getting the details exactly right is not crucial. A simple approach, based on the generally false assumption that the data are generated by a random walk, is nearly optimal. We use the tools discussed here to document a new fact: There has been a significant shift in the money–inflation relationship before and after 1960.  相似文献

This study examines conditions affecting consumer susceptibility to advertising deception and educational efforts designed to inoculate consumers against it. Results show that consumers are best able to detect deception when their frame of reference (cognitive or affective) is incongruent with the advertisement's executional style (attribute or emotional). Attempts to inoculate consumers against deception by providing factual brand comparisons have their strongest effect among consumers with an affective frame of reference and for emotionally charged ads.
Die Immunisierung von Konsumenten gegen werbliche Irreführung: Der Einflu der persönlichen Informationsausrichtung und des werblichen Argumentationsstils
Zusammenfassung Die Studie befa\t sich mit den Bedingungen werblicher Irreführung von Konsumenten und mit den Bemühungen der Verbrauchererziehung, Konsumenten durch vergleichende Warentestergebnisse gegen solche Irreführung zu immunisieren. Ihre Ergebnisse zeigen, da\ Konsumenten werbliche Irreführung am ehesten dann durchschauen, wenn ihre persönliche Informationsausrichtung (kognitiv oder affektiv) nicht mit dem werblichen Argumentationsstil (informativ oder emotional) übereinstimmt. Versuche, Konsumenten mit Hilfe vergleichender Warentest-Informationen gegen werbliche TÄuschung zu immunisieren, sind am wirkungsvollsten bei Konsumenten mit affektiver Informationsausrichtung und bei emotionshaltiger Werbung.

Roads, Land Use, and Deforestation: A Spatial Model Applied to Belize   总被引:24,自引:0,他引:24  
Rural roads promote economic development, but they also facilitatedeforestation. To explore this tradeoff, this article developsa spatially explicit model of land use and estimates probabilitiesof alternative land uses as a function of land characteristicsand distance to market using a multinomial logit specificationof this model. Controls are incorporated for the endogeneityof road placement. The model is applied to data for southern Belize, an area experiencingrapid expansion of both subsistence and commercial agriculture,using geographic information system (GIS) techniques to selectsample points at 1-kilometer intervals. Market access, landquality, and tenure status affect the probability of agriculturalland use synergistically, having differential effects on thelikelihood of commercial versus semisubsistence farming. Theresults suggest that road building in areas with agriculturallypoor soils and low population densities may be a "lose-lose"proposition, causing habitat fragmentation and providing loweconomic returns.  相似文献
