Benchmarking with DEA, SFA, and R

BUS462 Benchmarking with DEA, SFA, and R

  • Topics

    Topics

     First, we will discuss why to benchmark, the concepts of key performance indicators (KPIs), and different measures of efficiency and productivity (e.g., radial vs. non-radial measures; technical efficiency vs. cost efficiency).

    Second, efficiency measurement with the non-parametric and deterministic data envelopment analysis (DEA) is covered. The measurement of technical efficiency, cost efficiency, allocative efficiency, and scale efficiency will be discussed. The underlying assumptions and strength and weaknesses of this method are outlined.

    Third, efficiency measurement with stochastic frontier analysis (SFA) is covered. Starting from simple regression approaches based on ordinary least squares (OLS), we introduce models that incorporate noise and inefficiency simultaneously when estimating technical efficiency and cost efficiency. Underlying assumptions regarding functional forms and distributions are discussed, statistical inference and strength and weaknesses of this method are outlined.is outlined.

  • Learning outcome

    Learning outcome

    Benchmarking is the systematic performance evaluation of decision making units (DMUs), such as, e.g., firms, organizations, industries, or governments. The course will provide students with the following knowledge and skills:

    Knowledge

    • Foundations of efficiency analysis: concepts from production theory, efficiency & productivity
    • Understanding how Data Envelopment Analysis (DEA) and Stochastic Frontier Analysis (SFA) work, how they are estimated, and which advantages and disadvantages they offer
    • How to setup meaningful benchmarking models with DEA and SFA, which data is required, and how can results be interpreted

    Skills

    • Ability to carry out scientific benchmarking DEA and SFA using the statistical software R
    • Good practices in efficiency analysis including, e.g., descriptive data analysis, implementation of outlier detection methods, and the meaningful visualization of results

  • Teaching

    Teaching

    This course combines lectures, exercises, and programming tutorial. Lectures focus on methodological issues. Pen and paper exercises help to deepen the knowledge obtained in the lectures with illustrative examples. In programming tutorials, the student will implement the learned methodologies with real data sets using the free software R.

  • Recommended prerequisites

    Recommended prerequisites

    A basic understanding of microeconomic concepts such as production and cost functions is advised. First experience with linear programming and econometric estimation techniques is advantageous.

    Programming skills with R are helpful. However, if necessary, an additional introduction to programming with R will be offered.
