The research will start framing SDGs indicators within the Doughnuts Economics approach (Raworth 2017), which is gaining momentum in the academic literature and in real life projects. This will allow 1)assessing countries’ ability to live within the doughnut, 2) comparing countries via multicriteria assessment and/or robust composite indicators, 3) exploring trade-offs among the SDGs.The candidate will then go deeper into one of the most crucial sustainability puzzles, the working time–waste nexus. Why hasn't Keynes' prediction of a sharp reduction in the working week come true? Phenomena like planned obsolescence suggest that the impressive efficiency gains went to increase waste rather than reduce working time (Luzzati et al. 2022).Reducing both working time and waste would simultaneously affect the ecological and social variables of the doughnut.The candidate, together with the tutoring team, will decide the spatial level and geographical areas, the mix of the analytical tools, and the balance between the first and the second phases.Cited References: - Keynes, J.M., 2010 [1931].

Good knowledge and skills in quantitative economics/econometrics and traditional statistical tools (like PCA). Aquaintance with micro- and macroeconomics, particulary Industrial Organisation and Growth theory.

The research will be conducted within the Responsible Management Research Center at the Dip. di Economia and Management, a high interdisciplinary center in the field of SD to which I am affiliated. In particular, the expertise of professors D. Fiaschi, L. Gianmoena, A. Parenti, and dr V. Rios Ibanez in the fields of econometrics and theoretical growth models will complement mine in SD, multicriteria assessment and composite indicators. The student will also profit of the several competences available at two interdisciplinary Research Centers on sustainability of the University of Pisa (Energia per lo Sviluppo Sostenibile, CIRESS; Studio degli Effetti del Cambiamento Climatico, CIRSEC).
