CHOICE OF FLEXIBLE FUNCTIONAL FORMS: REVIEW AND APPRAISAL

Choice between alternative flexible functional forms has received little explicit treatment in many empirical agricultural studies. Theoretical criteria and empirical techniques for choosing between flexible functional forms are reviewed. Theoretical topics include definitions of flexibility, mathematical expansions, separability, and regular regions. Empirical techniques examined are Monte Carlo analysis, parametric modeling, bayesian inference, and nonnested hypothesis testing. Comparison of the full range of theoretical and empirical aspects may provide more credible and reliable empirical estimates when consumer or producer duality assumptions are appropriate in agricultural applications.Research Methods/ Statistical Methods,

Optimizing a Law School’s Course Schedule

[Excerpt] “Just like other educational institutions, law schools must schedule courses by taking into consideration student needs, faculty resources, and logistical support such as classroom size and equipment needs. Course scheduling is an administrative function, typically handled by an Assistant Dean or an Associate Dean, who works with the faculty and the registrar to balance these considerations in advance of the registration process. Usually, the entire academic year is scheduled in advance, although the spring semester may be labeled tentative until registration begins for that semester. It’s hard to imagine, but some schools even publish a two-year schedule of upper-division courses so that students can plan their entire law school career in advance. In order to give assistance to those academics involved for the first time in the scheduling process, this article discusses the law school scheduling process and how a scheduling software package has worked to successfully automate what has been seen as one of the most abysmal administrative tasks of an Associate Dean. We first provide a background to course scheduling at a typical law school. We then present a review of the tools for, and literature on, course scheduling, followed by a discussion of how technology can be applied to course scheduling in general, and our outcomes of applying this technology in a law school environment. We close with a brief summary.

COMPLACENT OR COMPETITIVE? BRITISH EXPORTERS AND THE DRIFT TO EMPIRE

The belief that Britain’s empire markets were soft is well entrenched in the literature. It is, however, a belief that has been largely untested. Indeed, the literature does not even offer an explicit definition of softness. This paper attempts to fill this gap by discussing the meaning of the term and, then, posing the question whether between 1870 and 1914 Britain’s fastest growing markets – Australasia and Canada – can in fact be reasonably labelled soft, as has often been assumed. The paper concludes that the demand for British imports in these markets were driven more by income and price considerations than by colonial sentiment or preference.Empire markets, soft markets, British exports, imperial sentiments

MARKET DEMANDS FOR BAGGED, REFRIGERATED SALADS

Sales of newly introduced bagged, refrigerated salads grew at over 50% annually, during 1994-95. Consumption of bagged salads displayed marked seasonality despite year-round availability and uniform quality at more stable prices than head lettuce. Using scanner data from 44 areas, a single-equation demand model incorporating the effects of weather on seasonal consumption is estimated. Statistical tests of aggregation indicate that weather-induced seasonality varies significantly across areas, as do own- and cross- price elasticities. Econometric results suggest more seasonality in eating by people living in more northern latitudes, a pattern also observed by psychiatrists studying eating disorders.Food Consumption/Nutrition/Food Safety,

DEMAND FOR ORGANIC AND CONVENTIONAL FROZEN VEGETABLES

In this paper, we examine retail sales of organic and conventional frozen vegetables (broccoli, green beans, green peas, and sweet corn) using supermarket scanner data. Descriptive analysis includes comparisons of sales volume, prices, and market shares. Price and expenditure elasticities are estimated using the almost ideal demands system (AIDS).organic foods, frozen vegetables, almost ideal demand system, Consumer/Household Economics, Demand and Price Analysis,

Labor Scheduling, Part 1: Forecasting Demand

This paper focuses on forecasting demand for services, the first of a four-part series on developing effective workforce schedules. Serving customers well, at a reasonable cost, requires the proper number and mix of employees. Scheduling too many employees means high labor costs, while scheduling too few workers can mean poor service that drives away business. Forecasting customer demand involves eight steps: determine the nature of the work, identify those factors that generate the work (i.e., the labor drivers), determine whether the labor drivers are time variant or time invariant, determine the time interval for tracking the time-variant labor drivers, forecast the time-variant labor drivers, smooth those forecasts, track the error in those forecasts, and define the allowable window for controllable work. Balancing employees\u27 skills and availability, plus governmental regulations, company policies, and contractual obligations regarding work schedules, can be a manager\u27s nightmare
