An aggregate analysis of supply response in the paddy (rice) sector of Sri Lanka during 1952-87 is conducted to identify the impact of pricing policy, irrigation programmes, institutional credit and concessional sales on area, yield and overall supply. The focus of the estimation procedure is the selection of an appropriate functional form for regressions and on the price variable that best represents the price to which producers respond in making area and yield decisions. In the case of both area and yield, the econometric criteria favour the acceptance of log-linear equations with the ratio of the guaranteed price of paddy to fertiliser price. On the basis of overall supply elasticity estimates, it is concluded that while pricing policy, irrigation programmes and institutional credit provide incentives to the expansion of paddy production, concessional sales of rice act as a disincentive. 相似文献

Prior to making important decisions, marketing managers go through an evaluation process in which available alternatives are
compared. Yet, no systematic discussion of the evaluation process exists in the marketing literature. This article reviews
the marketing and behavioral decision theory literature in order to identify factors that may cause errors in the two fundamental
elements of the evaluation process—the estimation of probabilities and the determination of the value of outcomes. Propositions
are developed that specify circumstances in which marketing management decisions may be influenced by judgmental biases, and
procedures are identified for debiasing such judgments. 相似文献

Up in the Air: GTE's Experience in the MTA Auction for Personal Communication Services Licenses 总被引:2,自引:0,他引:2

In late 1994, GTE, one of the largest telecommunications firms in the world, entered an auction for the rights to provide personal communications services (PCS) using the electromagnetic spectrum. The administering agency, the Federal Communications Commission, adopted a novel multiple-round format for the PCS auction. The format presented GTE with a complex bidding problem. This article describes how the GTE bidding team answered the following question: Given its budget and valuations and the information available about rival bidders, how should GTE bid to achieve the best attainable outcome? 相似文献

We extend the research on postinjury employment by estimating productivity losses for workers with permanent partial disabilities (PPDs) in the first three years after injury. Our method distinguishes between productivity losses attributed to spells of work absence versus reduced earnings during spells of employment. The method is applied to data for 800 Ontario workers with PPDs. The results document large productivity losses persisting at least three years after injury, with different loss patterns for workers returning to stable versus unstable employment. Human capital investments or job accommodations can reduce productivity losses, but the significant determinants of losses differ for the stable versus unstable employment groups. 相似文献

An interest charge is made up of an award for waiting known as the real rate of interest, a premium for risk and compensation for transaction costs. Where inflation exists the lender seeks further compensation. In order to understand the composition and evolution of different versions of the usury prohibition it is necessary to ask which components of an interest charge are prohibited by each version. The Judaic prohibition has two aspects which are of particular interest to business historians and students of usury. First, the general rule is that a reward for waiting is prohibited. This focuses on the time-based part of interest charge. Second, interest is prohibited because it amounts to placing a stumbling block before the blind. This focuses on the typical gullibility of the borrower confronted by a more expert, better funded lender. Economics confirms and enriches our understanding of these important aspects of the prohibition. They achieve this by increasing our understanding of two facts: first, that the borrower is a gullible individual subject to irrational and inconsistent behaviour; and, second, that this behaviour relates to the waiting aspect of interest which is proscribed in the prohibition. How far these insights apply to other civilisations' prohibition, particularly those which derive from the Judaic prohibition, merits further study; so also do the ethical lessons of the Mosaic rules for a globalised society based on capitalism. 相似文献

Predicting the geo-temporal variations of crime and disorder 总被引:2,自引:0,他引:2
Traditional police boundaries—precincts, patrol districts, etc.—often fail to reflect the true distribution of criminal activity and thus do little to assist in the optimal allocation of police resources. This paper introduces methods for crime incident forecasting by focusing upon geographical areas of concern that transcend traditional policing boundaries. The computerised procedure utilises a geographical crime incidence-scanning algorithm to identify clusters with relatively high levels of crime (hot spots). These clusters provide sufficient data for training artificial neural networks (ANNs) capable of modelling trends within them. The approach to ANN specification and estimation is enhanced by application of a novel and noteworthy approach, the Gamma test (GT). 相似文献
