Should You Do A Doctorate? The Changing Returns To Postgraduate Qualifications

Higher education in the UK has experienced radical change over the last two decades. The change has been driven by a number of factors, not least New Labour’s policy to send 50% of school leavers to university. The increased supply of graduates has weakened a first degree’s ability to function as a signal to employers, resulting in many individuals pursuing postgraduate study to make themselves more competitive. This paper aims to show the changing returns to Bachelor, Master and Doctoral degrees for the period 1997 to 2013 and recognises the increasing importance of Ph.D. graduates in the upcoming years

Persistence and Activation of Right-Wing Political Ideology

We investigate the persistence of right-wing ideology in Germany. The “Alternative for Germany” (AfD), founded as a party espousing fiscal conservatism, has turned to an openly nationalist and anti-immigrant platform since 2015. We document this rhetorical change with quantitative text analysis. We further show that municipalities that voted more for the AfD after 2015 also exhibited higher support for the Nazi party in the 1920s and 30s. The historical correlation we observe is positive, significant, and large. In our preferred specification, a one standard deviation increase in historical support for the Nazi party is associated with a 0.15 standard deviations larger change in votes towards the AfD. Our results are robust to controlling for a large set of historical and contemporary covariates, especially relating to unemployment and the recent inflow of refugees from the Middle East

Digitalization Platform for Sustainable Battery Cell Production: Coupling of Process, Production, and Product Models

Lithium-ion batteries are used in a wide range of applications, with the electromobility sector being the main contributor to the increasing demand predicted for the next decade. Although batteries play an important role in decarbonizing the transportation sector, their production includes energy-intensive processes that hinder a more sustainable production. Moreover, the production processes are characterized by a manifold of parameters leading to complex cause–effect relations along the process chain which influences the battery cell quality. Therefore, a sustainable future for battery production and the electromobility sector depends on the environmentally and economically efficient production of high-performance batteries. Against this background, this work presents a digitalization platform based on the coupling of mechanistic models to digitally reproduce the battery cell production and provide a deeper understanding of the interdependencies on the process, production, and product levels. In addition to a description of the individual models contained in the platform, this work demonstrates their coupling on a use case to study the effects of different solids contents of the coating suspension. Besides providing a multilevel assessment of the parameter interdependencies, considering quality, environmental and economic aspects, the presented framework contributes to knowledge-based decision support and improvement of production and battery cell performance

Persistence and Activation of Right-Wing Political Ideology

We argue that a long-run cultural persistence of right-wing ideology can explain the recent rise of right-wing populism. Shifts in the supply of party platforms can interact with this existing demand, and give rise to patterns of historical persistence. We study the context of Germany in the 2017 federal election, when the emergence of the AfD offered voters a populist right-wing option, with little social stigma attached. We show that municipalities that expressed strong support for the Nazi party in 1933 are more likely to vote for the AfD now, but not in 2013, when the AfD was a more moderate, fiscally conservative party. Using opinion surveys, we show that these dynamics are not generated by a concurrent demand shift: political attitudes do not shift sharply to the right in the municipalities with a history of Nazi support

Did COVID-19 Boost Populism? Evidence from Early Superspreader Events

We study whether right-wing populists benefited from the onset of the COVID-19 pandemic. Exploiting variation in COVID-19 incidence stemming from the idiosyncratic timing of superspreader events in early 2020, we find a spike in online engagement with populists in European regions with higher infection rates. We document a similar boost in populist support in French municipal elections as well as individual-level British and Dutch survey data. Declining institutional trust, intensifying outgroup hostility, and opposition to government restrictions, these varied sources suggest, fueled the populist surge. The findings broaden our understanding of the types of societal shocks that foster extreme politics

Accommodation of Right-Wing Populist Rhetoric: Evidence From Parliamentary Speeches in Germany

We provide novel evidence on how right-wing (populist) rhetoric spreads. Using several thousand speeches from the German parliament, we show that exposure to politicians from the right-wing populist Alternative for Germany (AfD) leads mainstream politicians to adopt a more distinctively right-wing populist language. We measure similarity to right-wing populist rhetoric via cosine similarity to both parliamentary speeches by the AfD and extremist speeches at far-right rallies, as well as using a populist dictionary method. To induce individual-level variation in exposure to AfD politicians, we exploit a quasi-exogenous allocation rule for committee members in the German parliament. Comparing a politician with the highest to one with the lowest relative AfD exposure increases the cosine similarity to right-wing populist speech by 0.1 of a standard deviation. Our results seem specific to right-wing populism and suggest strategic motives related to local electoral competition behind rhetorical changes among individual politicians
