On 19 February 2026, a methodological workshop was held at the Faculty of Economics and Business in Osijek for members of the IPZET project team – Integrated Approach to the Economic Challenges of the Green Transition. The workshop was led by Prof. dr. sc. Đula Borozan and was dedicated to the methodological challenges of calculating and interpreting green technical efficiency and total factor productivity.
During the workshop, participants were introduced to key methodological concepts relevant to the implementation of the project’s research, including the Data Envelopment Analysis (DEA) method and the Malmquist-Luenberger productivity index as tools for measuring green total factor productivity while accounting for undesirable outputs such as CO2 emissions. The practical part of the workshop included an example of calculating technical efficiency using the Stata statistical software.
The workshop was conducted as part of the planned activities for the first year of the project, with the aim of standardising the methodological knowledge and skills of the research team members as a prerequisite for the execution of the planned studies.
