Flechtner, S. (2020): "Behavioural development economics - progress or fad?", work in progress.

The history of development economics has been interpreted as a succession of fads and magic bullets. This paper enquires if and to what extent behavioural approaches could or should be understood as such a fad. I argue that to be more than a magic bullet that must lead to disappointment after a phase of exaggerated enthusiasm, two conditions must be met. First, behavioural approaches to development must advance our theoretical understanding of development processes. Second, behavioural approaches must improve the quality and effectiveness of policy recommendations. This paper argues the degree to which behavioural development economics (BDE) will be able to respond to these expectations depends on how the field continues to understand itself. BDE is not yet a cohesive field with a consensual self-definition. I portray three different views of BDE: the scarcity view, the non-optimal behaviour view, and the psycho-social-cultural-view. Identifying BDE publications from the Web of Science from 2000-2019, I illustrate to which view publications have belonged, and discuss implications for advances in terms of theoretical understanding of behaviour as well as policy recommendations.  I argue that to be successful, the field should embrace the psycho-social-cultural view more enthusiastically, at the expense of the pure non-optimal behaviour view.


Flechtner, S. und Gräbner, C. (2019): The inequality-growth nexus

In this project, we are interested in the inequality-growth nexus. We started with a study of the relationship between per-capita income and income inequality with a heterogeneous panel co-integration approach. We extended previous studies in two ways: first, we compiled a more extensive data set for 61 countries over 26-51 years and considered measures for both pre-tax and post-tax income inequality; second, we take into account country heterogeneity rather than focussing on average panel estimates alone. It turns out that we found a negative group-mean based relationship using pre-tax income inequality, but no such relationship for post-tax income inequality. Moreover, we find estimates on the country level to be heterogeneous in both cases. The results have been published in the Economics Bulletin here. Previous results with a smaller dataset were published the as ICAE Working Paper 91. Data and code are on Github.

Following up on these results, we are now interested in understanding the heterogeneity in country experiences.

D'Ippoliti, C. & Flechtner, S. (2019): "Fields of study choices and the reproduction of income inequalities", working paper.

In this paper, we study fields of study choices of secondary school graduates in Germany, which are highly consequential for their later income earnings. We analyze how the students' likelihood of entering different fields of study choices changes in accordance with different individual characteristics (students' field-specific abilities, preferences, grades), field characteristics (expected income, share of women in the field), and socio-economic characteristics (socio-economic background incl. migration background, gender). We use data from the German school-leavers panel 2008, featuring data of about 27,000 students in their last year of upper secondary education, and use nested logistic regressions to analyse the fields of study choices students indicate, considering all other options they face at the individual level.

Our results indicate that individual characteristics are more important in determining a students' choice than characteristics of the fields. We confirm the relevance of different explanations put forward in the literature, in particular regarding field-specific skills. On the other hand, the explanatory power of the individual variables and explanations is rather low. The share of choices we can correctly predict increases and decreases very little with the inclusion of variables such as specific skills, preferences or grades. At the same time, controlling for all these factors, a gender dummy remains highly significant and reduces the share of correct prediction by about the same size as specific skills when taken out of the model. This means that the various explanations of gendered field of study choices that are discussed in an interdisciplinary body of research do not offer a full explanation.

This short note with Torsten Heinrich came about as a reply to a paper that we replicated. It might be useful for people interested in understanding measures of fit to interpret sufficiency in fuzzy-set qualitative comparative analysis (fsQCA).
