KonSi Malmquist Index Software is a specialized Data Envelopment Analysis (DEA) tool designed to measure, evaluate, and track changes in the productivity of Decision Making Units (DMUs) across multiple time periods. By utilizing linear programming to construct a non-parametric efficiency frontier, it eliminates the need to guess or assume arbitrary structural relationships between variables.
To optimize efficiency using this software, users must look past baseline efficiency scores and isolate the underlying root causes of shifting performance over time. Core Analytical Decompositions
The framework utilizes the classic Färe et al. decomposition of the Malmquist Productivity Index (
). The software computes distance functions across adjacent time periods (
) to segment total factor productivity change into actionable data categories:
┌──────────────────────────────┐ │ Malmquist Index Score (M) │ └──────────────┬───────────────┘ │ ┌───────────────────────┴───────────────────────┐ ▼ ▼ ┌──────────────────┐ ┌──────────────────┐ │ Technical Change │ │ EfficiencyChange │ │ (Frontier Shift) │ │ (Catch-Up) │ └──────────────────┘ └────────┬─────────┘ │ ┌───────────────┴───────────────┐ ▼ ▼ ┌────────────────────┐ ┌────────────────────┐ │ Pure Efficiency │ │ Scale Efficiency │ │ Change │ │ Change │ └────────────────────┘ └────────────────────┘
