Evaluating efficiency-effectiveness-equality trade-offs: a Data Envelopment Analysis approach
Article Abstract:
A resource allocation model that extends the Data Envelopment Analysis (DEA) methodology is presented. Aside from measuring efficiency, the original objective of DEA, the model also assesses the different aspects of effectiveness and equality considerations. It can be used for resource allocation purposes even in the absence of a priori assumptions regarding the form of the underlying production function. Furthermore, the model can consider issues of efficiency, effectiveness and equality, and examine tradeoffs among them all at the same time. It is designed as linear program that can be solved using a Dantzig-Wolfe decomposition algorithm. A comparison is made between the theoretical properties of the resource allocation model and those of the Mandell (1991) model.

Using rank statistics for determining programmatic efficiency differences in Data Envelopment Analysis
Article Abstract:
An analytical technique designed to evaluate programs within Data Envelopment Analysis (DEA) efficiency evaluation framework is considered. This approach recognizes possible differences in managerial and programmatic performance. It measures the statistical significance of observed differences between a treatment and a control group program by using the Mann-Whitney rank statistic and taking into account differences in managerial efficiency between the programs. The proposed statistical procedures are demonstrated using a numerical example. This analysis shows the potential of nonparametric rank statistics for assessing the statistical significance of variances in program efficiency across programs without neglecting managerial efficiencies.

A note on including ordinal relations among multipliers in data envelopment analysis
Article Abstract:
Data Envelopment Analysis (DEA) is used to evaluate decision-making units without imposing a priori weights on the output and input dimensions involved. DEA is extended to situations in which weights corresponding to certain dimensions have ordinal relations. An example of DEA is presented and areas of possible application are suggested.

my lecturer said that effectivess model is comparing between output and input, but i find in another article that effectivess is comparing between input and outcome. which one is right?
