Purpose: This study evaluates the impact of an outsourced extension service delivered by Lima Rural Development Foundation (Lima) in the Umzimkhulu district of South Africa. The evaluation is conducted at both the household and program levels. Design/methodology/approach: Household impacts were estimated using two-stage regression with…

Given the necessity to bridge the gap between what happened and what is likely to happen, this paper aims to explore how to apply Bayesian inference to cost-effectiveness analysis so as to capture the uncertainty of a ratio-type efficiency measure. The first part of the paper summarizes the characteristics of the evaluation data that are commonly…

Early childhood education programs play an important role in child family-to-school transition. In 1998, California voters passed Proposition 10, the California Children and Families Act, which levied a 50-cent tax on each pack of cigarettes and other tobacco products to finance programs for children ages 0-5. In less than two decades, First 5…

This research paper explores the concept of "cost sharing" which became more prominent in Zambia education with the advent of democratic form of governance in 1991. As a way of responding to the ever diminishing tax revenues, government through the education policy of 1996, allowed higher education institutions including public…

Five data collection techniques and two sampling methods were examined in terms of costs, rates of return, quality of the data collected, and degree of representativeness in assessing needs and interests of public television viewers in rural areas. Data collection techniques were (1) mail only, (2) mail incentive, (3) telephone only, (4) mail and…

Two sampling designs were compared for the planned 1978 national longitudinal survey of high school seniors with respect to statistical efficiency and cost. The 1972 survey used a stratified two-stage sample of high schools and seniors within schools. In order to minimize interviewer travel costs, an alternate sampling design was proposed,…

Tracking and two statistical methods (probability weighting and sample selection modeling) were studied as ways to minimize bias attributable to sample attrition in school-based studies. Data on student smoking from 30 middle schools illustrate that sample weighting yields the best results, with estimates superior to sample selection and much less…

Inferences that might be made from international educational assessments are discussed, considering issues of popular definition and sampling, assessment exercises, background variables, and statistical analyses. International assessments do tell something about academic achievement, but other approaches may provide more cost-effective information…

The methodology to perform benefit-cost studies exists, but there is much ambiguity concerning the implications of such studies as a result of using faulty methodology. For example, control groups are a necessity, as are adequate sampling procedures and adjustment for non-response bias and self-selection bias, and all studies do not employ this…

Latent trait model calibration procedures were used on data obtained from a group testing program. The one-parameter model of Wright and Panchapakesan and the three-parameter logistic model of Wingersky, Wood, and Lord were selected for comparison. These models and their corresponding estimation procedures were compared, using actual and simulated…

The National Job Corps Study was conducted in 1994-1996 to provide a thorough and rigorous assessment of the impacts of the Job Corps on key participant outcomes. To ensure that the study was well implemented, a study team from Mathematica Policy Research, Inc., (MPR) investigated outcome and admission (OA) procedures in each Job Corps region and…
