While the impact of digitalization on education was already a point of serious deliberation, the COVID-19 pandemic has expedited ongoing transitions. With 90% of the world’s student population having been impacted by national lockdowns—online learning has gone from being a luxury to a necessity, in a context where around 3.6 billion people are offline. As the impacts of the 4IR unfold alongside the current crisis, it is not enough for future policy pathways to prioritize educational attainment in the traditional sense; it is essential to reimagine education itself as well as its delivery entirely. Future policy narratives will need to evaluate the very process of learning and identify the ways in which technology can help reduce existing disparities and enhance digital access, literacy and fluency in a scalable manner. In this context, this chapter analyses the status quo of online learning in India and Germany. Drawing on the experiences of these two economies with distinct trajectories of digitalization, the chapter explores how new technologies intersect with traditional education and local sociocultural conditions. Further, the limitations and opportunities presented by dominant ed-tech models is critically analyzed against the ongoing COVID-19 pandemic.

We study distributional implications of seasonal weather and climate on within-country inequality in rural India. Utilizing a first difference approach, we find that the poor are more sensitive to weather variations than the non-poor. The poor respond more strongly to (seasonal) temperature changes: negatively in the (warm) spring season, more positively in the (cold) rabi season. Less precipitation is harmful to the poor in the monsoon kharif season and beneficial in the winter and spring seasons. We show that adverse weather aggravates inequality by reducing consumption of the poor farming households. Future global warming predicted under RCP8.5 is likely to exacerbate these effects, reducing consumption of poor farming households by one third until the year 2100. We also find inequality in consumption across seasons with higher consumption during the harvest and lower consumption during the sowing seasons.

We first provide detailed descriptive evidence of changes to the wage structure in particular at the bottom of the distribution and distinguish between trends for regularly employed and marginally employed workers. In the causal analysis, we then employ a differential trend adjusted difference-in-differences (DTADD) strategy to identify the extent to which these changes in wages and earnings can be attributed to the minimum wage introduction. We find that the minimum wage introduction can account for hourly wage growth in the order of roughly 6.5 % or (sic)0.45/hour and an increase in monthly earnings of 6.6 % or (sic)53/month. Despite finding wage growth at the bottom of the distribution, the paper documents widespread non-compliance with the mandated wage floor of (sic)8.50/hour.

Using detailed Socio-Economic Panel survey data, we assess changes in the hourly wages, working hours, and monthly wages of employees who were entitled to be paid the minimum wage. We employ a difference-in-differences analysis, exploiting regional variation in the “bite” of the minimum wage. At the bottom of the hourly wage distribution, we document wage growth of 9% in the short term and 21% in the medium term. At the same time, we find a reduction in working hours, such that the increase in hourly wages does not lead to a subortionate increase in monthly wages. We conclude that working hours adjustments play an important role in the distributional effects of minimum wages.

BT - cross-country evidence on productivity differences between male and female software developers JF - Journal of family research N2 - Objective: This article analyzed gender differences in professional advancement following the outbreak of the Covid-19 pandemic based on data from open-source software developers in 37 countries. Background: Men and women may have been affected differently from the social distancing measures implemented to contain the Covid-19 pandemic. Given that men and women tend to work in different jobs and that they have been unequally involved in childcare duties, school and workplace closings may have impacted men's and women's professional lives unequally. Method: We analyzed original data from the world's largest social coding community, GitHub. We first estimated a Holt-Winters forecast model to compare the predicted and the observed average weekly productivity of a random sample of male and female developers (N=177,480) during the first lockdown period in 2020. To explain the crosscountry variation in the gendered effects of the Covid-19 pandemic on software developers' productivity, we estimated two-way fixed effects models with different lockdown measures as predictors - school and workplace closures, in particular. Results: In most countries, both male and female developers were, on average, more productive than predicted, and productivity increased for both genders with increasing lockdown stringency. When examining the effects of the most relevant types of lockdown measures separately, we found that stay-at-home restrictions increased both men's and women's productivity and that workplace closures also increased the number of weekly contributions on average - but for women, only when schools were open. Conclusion: Having found gender differences in the effect of workplace closures contingent on school and daycare closures within a population that is relatively young and unlikely to have children (software developers), we conclude that the Covid-19 pandemic may indeed have contributed to increased gender inequalities in professional advancement.

This dissertation seeks to advance our understanding of when and how climate migration emerges by analyzing heterogeneous climatic influences on migration in low- and middle-income countries. To this end, it draws on established economic theories of migration, datasets from physical and social sciences, causal inference techniques and approaches from systematic literature review. In three of its five chapters, I estimate causal effects of processes of climate change on inequality and migration in India and Sub-Saharan Africa. By employing interaction terms and by analyzing sub-samples of data, I explore how these relationships differ for various segments of the population. In the remaining two chapters, I present two systematic literature reviews. First, I undertake a comprehensive meta-regression analysis of the econometric climate migration literature to summarize general climate migration patterns and explain the conflicting findings. Second, motivated by the broad range of approaches in the field, I examine the literature from a methodological perspective to provide best practice guidelines for studying climate migration empirically. Overall, the evidence from this dissertation shows that climatic influences on human migration are highly heterogeneous. Whether adverse climate-related impacts materialize in migration depends on the socio-economic characteristics of the individual households, such as wealth, level of education, agricultural dependence or access to adaptation technologies and insurance. For instance, I show that while adverse climatic shocks are generally associated with an increase in migration in rural India, they reduce migration in the agricultural context of Sub-Saharan Africa, where the average wealth levels are much lower so that households largely cannot afford the upfront costs of moving. I find that unlike local climatic shocks which primarily enhance internal migration to cities and hence accelerate urbanization, shocks transmitted via agricultural producer prices increase migration to neighboring countries, likely due to the simultaneous decrease in real income in nearby urban areas. These findings advance our current understanding by showing when and how economic agents respond to climatic events, thus providing explicit contexts and mechanisms of climate change effects on migration in the future. The resulting collection of findings can guide policy interventions to avoid or mitigate any present and future welfare losses from climate change-related migration choices. N2 - Während die geschätzten Zahlen zukünftiger Klimamigranten alarmierend sind, deuten die wachsenden empirischen Belege darauf hin, dass der Klimawandel nicht automatisch zu mehr Migration führt. Denn auch wenn klimabezogene Einflüsse die Entscheidung zur Migration zunehmend beeinflussen, wird diese durch eine Vielzahl von Faktoren, wie beispielsweise den sozioökonomischen und politischen Bedingungen, beeinflusst. Der Zusammenhang zwischen Klimawandel und Migration ist also stark kontextabhängig. Diese Dissertation besteht aus fünf Artikeln und zeigt, wann und wie Klimamigration entsteht, indem sie die heterogenen klimatischen Einflüsse in Entwicklungsländern untersucht. Gestützt auf ökonomische Migrationstheorien analysiere ich Datensätze aus den Natur- und Sozialwissenschaften mithilfe von Methodiken der ökonometrischen Kausalanalyse, der Geoinformationssysteme und der systematischen Literatursynthese. In drei von fünf Kapiteln schätze ich die kausalen Auswirkungen des Klimawandels auf Ungleichheit und Migration in Indien und Subsahara Afrika. Durch die Verwendung von Interaktionstermen und die Analyse von Teilstichproben untersuche ich in Regressionsmodellen, wie sich diese Beziehungen für verschiedene Bevölkerungsgruppen unterscheiden. In den verbleibenden zwei Kapiteln fasse ich die ökonometrische Literatur zur Klimamigration systematisch zusammen. Zunächst führe ich eine umfassende Meta-Regressionsanalyse durch, um die allgemeine Klimamigrationsmuster zusammenzufassen und die widersprüchliche Evidenz zu erklären. In einem zweiten Schritt untersuche ich die ökonometrische Klimamigrationsliteratur aus einer methodologischen Perspektive, um Best-Practice-Leitlinien für künftige empirische Analysen von Klimamigration bereitzustellen. Insgesamt bestätigen die Ergebnisse dieser Dissertation, dass die klimatischen Einflüsse auf menschliche Migration heterogen sind und von den sozioökonomischen Merkmalen der einzelnen Haushalte wie dem Wohlstand und Bildungsniveau, der Abhängigkeit von der Landwirtschaft oder dem Zugang zu Anpassungstechnologien und Versicherungen, mitbestimmt werden. Ich finde beispielsweise, dass ungünstige klimatische Schocks zu einem Migrationsanstieg im ländlichen Indien führen, sie aber die Migration im landwirtschaftlichen Subsahara Afrika, wo das durchschnittliche Einkommensniveau viel niedriger ist, verhindern. Ich habe zudem herausgefunden, dass im Gegensatz zu lokalen klimatischen Schocks, die in erster Linie die Binnenmigration in die Städte verstärken und damit die Urbanisierung beschleunigen, globale Schocks über landwirtschaftliche Erzeugerpreise die Abwanderung in benachbarte Länder antreiben. Diese Ergebnisse erweitern unser derzeitiges Verständnis, indem sie verdeutlichen, wann und wie Akteure auf unterschiedliche Klimaereignisse mit der Entscheidung zur Migration reagieren. Die daraus resultierenden Erkenntnisse können helfen, Entscheidungsträger auf drei wichtige Arten zu informieren. Erstens, wenn man weiß, wer die Klimamigranten sind und welche Destinationsziele sie wählen, wird Klimamigration vorhersehbarer und damit kontrollierbarer. Dies kann verhindern, dass sie zu einer humanitären Krise wird. Zweitens hilft die Identifizierung von Bevölkerungsgruppen, die nicht in der Lage sind, sich durch Migration an die veränderten klimatischen Bedingungen anzupassen, dabei, unfreiwillige Immobilität zu vermeiden, was wiederum auch eine potenzielle humanitären Krise verhindert. Drittens können all diese Informationen helfen, Kosten und Nutzen der Klima(im)mobilität genauer zu bewerten und so die Social Cost of Carbon genauer einzuschätzen.

It develops a two-skill-type spatial equilibrium model of two regions with location preferences where each region consists of an urban area that is home to workplaces and residences and an exclusively residential suburban area. The paper demonstrates that relative regional social mobility is negatively correlated with segregation and inequality. In the model, segregation, income inequality, and social mobility are driven by differences between urban and residential areas in commuting cost differences between high-skilled and low-skilled workers, and also by the magnitude of taste heterogeneity.

It has been suggested that under poor conditions when inequality within a population increases, also the variability in height tends to increase. We studied the association of body height, within-country variability in height and geographic and historic origin in 767 growth studies carried out in 80 countries, published between 1794 and 2013, with data on N = 78,184 infants age 2 years, and N = 2,130,729 juveniles age 7 years. The studies represent almost the whole spectrum of economic diversity in human societies since the end-18 th century. 207 studies contained data for both infants and juveniles with 50,819 subjects (age 2), and 123,078 subjects (age 7). Multiple linear regressions showed significant interactions between height, sex, historic year of the study, geographic origin, and within-study standard deviation for height with multiple R-squared = 0.527, p < 0.001, at age 2, and multiple R-squared = 0.436, p < 0.001, at age 7. Yet, the two age groups differed in respect to within-study standard deviation for height. We found a significant association between body height and within-study standard deviation for height only at age 2: tall infant populations are less variable in height (r = –0.27, p < 0.01). There was no such association in children aged 7 years. Tall children from affluent and short children from less affluent countries do not differ in the variability of body height. The data suggest that the 'environmental adversity' hypothesis for variation in growth: small mean values for height go along with large standard deviations for height, does not apply for children at age 7.
