(2020): Does online fundraising increase charitable giving? : A nation-wide field experiment on Facebook
Does online fundraising increase charitable giving? We implemented a natural field experiment across Germany, randomly assigning all of the country's 8,000 zip codes to Save the Children Facebook fundraising videos or a pure control and studied changes in the volume of donations to this and other similar charities by zip code. Our design circumvents many shortcomings inherent in studies based on click-through data, especially substitution and measurement issues. We found that (i) the video fundraising increased donation frequency and value to Save the Children during the campaign and in the subsequent five weeks; (ii) the campaign was profitable for the fundraiser; and (iii) the effects were similar independent of the video content and impression assignment strategy. However, we also found that the overall volume of donations does not increase, due to a massive crowding out of donations to other similar charities. Finally, we demonstrate that click data are an inappropriate proxy for donations.

(2020): Falling Apart or Flocking Together? : Financial Crises, Inequality and Left-Right Polarization in the OECD
Project : From Bad to Worse: Financial Crises, Polarization, and Inequality
According to the conventional wisdom, political polarization has been growing in the past few decades, and increasing inequality and financial crises have fuelled this trend. Making use of new measures and differentiating between parliamentary and electoral polarization across the left-right cleavage, this article offers a comparative evaluation of this claim for the OECD countries. The results show that the electorates in the European Union have become more conflictive, while the political parties represented in the national parliaments have moved in opposite direction. The statistical analysis demonstrates in line with the theoretical expectations that currency crises have increased mass polarization. The article also offers some tentative support for the hypothesis that increased levels of income inequality enhance this trend and that growing elite discord increases the left-right confrontation in the electorate.

Vertrauen ist wichtiger als Eigeninteresse: Das zeigt eine OnlineBefragung, die wir von April bis Mai 2020 unter knapp 4800 Teilnehmenden durchgeführt haben. Die Haltung zur Lockerung pandemiebedingter Beschränkungen wird weniger dadurch bestimmt, ob jemand daraus wirtschaftliche oder familiäre Folgen für sich selbst oder die Gesellschaft befürchtet. Vielmehr bringen wahrgenommene Grundrechtseinschränkungen die Befragten dazu, Lockerungen zu fordern. Befragte aus dem Osten Deutschlands und solche, die ohnehin ein geringes Vertrauen in staatliche Institutionen haben, sehen die Eindämmungsmaßnahmen besonders kritisch. Bei der Lockerungsdiskussion geht es also weniger um unterschiedlich starke individuelle Betroffenheit als um das Vertrauen in staatliche Institutionen.

(2020): Performance difference in verbal fluency in bilingual and monolingual speakers Bilingualism : Language and Cognition. Cambridge University Press (CUP). 2020, 23(1), pp. 204-218. ISSN 1366-7289. eISSN 1469-1841. Available under: doi: 10.1017/S1366728918001098
Research has shown that bilinguals can perform similarly, better or poorly on verbal fluency task compared to monolinguals. Verbal fluency data for semantic (animals, fruits and vegetables, and clothing) and letter fluency (F, A, S) were collected from 25 Bengali–English bilinguals and 25 English monolinguals in English. The groups were matched for receptive vocabulary, age, education and non-verbal intelligence. We used a wide range of measures to characterize fluency performance: number of correct, fluency difference score, time-course analysis (1st RT, Sub-RT, initiation, slope), clustering, and switching. Participants completed three executive control measures tapping into inhibitory control, mental-set shifting and working memory. Differences between the groups were significant when executive control demands were higher such as number of correct responses in letter fluency, fluency difference score, Sub-RT, slope and cluster size for letter fluency, such that bilinguals outperform the monolinguals. Stroop performance correlated positively with the slope only for the bilinguals.

(2020): Online psycholinguistic methods in second language acquisition research CHAPELLE, Carol A., ed.. The Concise Encyclopedia of Applied Linguistics. Hoboken: Wiley Blackwell, 2020, pp. 859-870. ISBN 978-1-119-14736-7
Second language acquisition (SLA) research has traditionally used paper-and-pencil tasks, such as grammaticality judgment and completion tasks. In such tasks, participants usually have time to read the whole sentence, they can think and reflect about its form and meaning, and then make a conscious judgment about its grammaticality or how to complete it. This is why these tasks are called offline; that is, the information we get is after the participant has read the whole sentence and has had time to think about it. This is in contrast to online methods that measure how participants process sentences as they unfold word by word or phrase by phrase; that is, these methods measure how participants process sentences in real time. This entry focuses on widely used behavioral online methods, and will provide a short introduction to four such methods recently used in SLA research to address how second language (L2) learners process sentences in real time. These methods are: (a) word monitoring, (b) self-paced reading/listening, (c) cross-modal priming, and (d) self-paced listening with picture verification. Each method is described with examples from key L2 studies. This is followed by a section discussing the advantages and disadvantages of each of these methods. The final section provides a brief overview of eye-tracking, a behavioral method which is gaining popularity in the field, along with its advantages and disadvantages.

(2020): Explaining the uneven demand for EU parliamentary oversight during the Eurozone crisis LSE EUROPP blog
Project : From Bad to Worse: Financial Crises, Polarization, and Inequality
The Eurozone crisis increased calls for institutional reform and closer parliamentary oversight of the EU’s crisis managers. As Federica Genovese and Gerald Schneider show, the national demand for increased parliamentary scrutiny crucially hinged on the exposure to the crisis and the domestic leeway in fighting it.

(2020): Going beyond values versus self-interest : whose attitudes change after employment transitions? Political Research Exchange. Routledge, Taylor & Francis Group. 2020, 2(1), 1809473. eISSN 2474-736X. Available under: doi: 10.1080/2474736X.2020.1809473
Are self-interest or presumably stable value orientations and other predispositions the main drivers behind social policy attitudes? This article contributes to this debate by moving away from its binary discussion. It differentiates between attitude changes driven by self-interest that are in line with pre-existing predispositions and those that are not. Empirically, this article focuses on changes of labour market policy attitudes after employment transitions and job insecurity changes. More precisely, this article differentiates between attitude changes within three subgroups. (A) People whose self-interest after the employment transitions reinforces their prior predispositions. (B) People without strong prior predispositions, who are thus unconstrained by them. And (C) people whose self-interest after the employment transitions contradicts their prior predispositions. Panel analyses with fixed effects use German SOEP waves from 1997 and 2002. Main effects suggest an important role for self-interest as they show significant attitudinal reactions after most of the transitions and perception changes. However, subgroup analyses result in a somewhat mixed picture. They show attitude changes within different subgroups after different transitions and perception changes. This mixed empirical picture suggests caution when interpreting attitudinal change or stability after changing material circumstances as a sign for the relative importance of self-interest or predispositions.

In many games of imperfect information, players can make Bayesian inferences about other players’ types based on the information that is contained in their own type. Several behavioral theories of belief-updating even start from the assumption that players project their own type onto others also when it is not rational. We investigate such inferences in a simple laboratory task, in which types are drawn from one out of two states of the world and participants have to guess the type of another participant. We nd lile evidence for irrational (over-)projection. Instead, between 50% and 70% of the participants in our experiment completely neglect the information contained in their own type and base their choices only on the prior probabilities. Using several experimental interventions, we show that this striking neglect of information is very robust.

Trust matters more than self-interest: That is the result of an online survey we conducted among roughly 4,800 participants in April and May 2020. Individual attitudes towards easing restrictions to contain the coronavirus pandemic are not primarily shaped by whether people fear economic or family-related consequences for themselves or for society. Rather, it is perceived infringements on basic rights that motivate respondents to demand that restrictions be lifted. Respondents from East Germany and those who tend not to trust public institutions in the first place are especially critical of the containment measures. The discussion about easing restrictions, therefore, is not so much about the varying degrees to which individuals are affected, but rather about the degree of trust in public institutions generally.

Empirical research in the economics of education often addresses causal questions. Does an educational policy or practice cause students' test scores to improve? Does more schooling lead to higher earnings? This article surveys the methods that economists have increasingly used over the past two decades to distinguish accidental association from causation. The methods include research designs that exploit explicit randomization as well as quasi-experimental identification strategies based on observational data. All methods are illustrated with a range of selected example applications from the economics of education.

Die Corona-Krise hat für viele Beschäftigte zu einer schnellen und tiefgreifenden Veränderung ihres Arbeitsalltags geführt. Zur Einhaltung sozialer Distanzierung haben private und öffentliche Organisationen ihre Belegschaft ganz oder teilweise ins Homeoffice geschickt. Die vorliegende Studie vermisst diese neue Arbeitswelt auf einer einzigartigen Datengrundlage: Einer Umfrage unter rund 700 Beschäftigten im Homeoffice über neun Erhebungszeitpunkte hinweg. Die Ergebnisse zeigen, dass die empfundene Produktivität und das Engagement der Beschäftigten durch die Arbeit im Homeoffice gefördert werden und sich eine große Mehrheit wünscht, zumindest teilweise weiterhin mobil zu arbeiten. Jedoch wird auch eine Tendenz zu Mehrarbeit und damit einhergehender Erschöpfung deutlich. Das erhöht den Handlungsdruck für die Politik und die Vertretungen von Betrieben und Beschäftigten. Die Studie schließt mit Empfehlungen, wie die Rahmenbedingungen für das Arbeiten im Homeoffice verbessert werden können.

(2020): Agent based models in Mata : Modelling aggregate processes, like the spread of a disease London Stata Conference 2020. 2020
An Agent Based Model (ABM) is a simulation in which agents that each follow simple rules interact with one another and thus produce an often surprising outcome at the macro level. The purpose of an ABM is to explore mechanisms through which actions of the individual agents add up to a macro outcome by varying the rules that agents have to follow or varying with whom the agent can interact (for example, varying the network). These models have many applications, like the study of segregation of neighborhoods or the adoption of new technologies. However, the application that is currently most topical is the spread of a disease. In this talk, I will give introduction on how to implement an ABM in Mata, by going through the simple models I (a sociologist, not an epidemiologist) used to make sense of what is happening with the COVID-19 pandemic.

Donald Trump, the Arab Spring, Brexit: digital media have provided political actors and citizens with new tools to engage in politics. These tools are now routinely used by activists, candidates, non-governmental organizations, and parties to inform, mobilize, and persuade people. But what are the effects of this retooling of politics? Do digital media empower the powerless or are they breaking democracy? Have these new tools and practices fundamentally changed politics or is their impact just a matter of degree? This clear-eyed guide steps back from hyperbolic hopes and fears to offer a balanced account of what aspects of politics are being shaped by digital media and what remains unchanged. The authors discuss data-driven politics, the flow and reach of political information, the effects of communication interventions through digital tools, their use by citizens in coordinating political action, and what their impact is on political organizations and on democracy at large.

(2020): Working from home in the Coronavirus crisis : Towards a transformation of work environments?
The coronavirus crisis has brought rapid and sweeping changes to the daily work life of many employees. To comply with social distancing rules, many private and public organizations let all or part of their staff work from home. This study analyzes this new work environment on the basis of unprecedented data: a survey conducted at nine points in time among roughly 700 telecommuting employees. The results demonstrate that employees working from home show an increase in perceived productivity and commitment. The vast majority wish to continue to work flexibly on a remote basis, at least to some extent. However, we also observe a trend towards excessive workloads resulting in exhaustion. This increases the urge for policymakers and employee representations to take action. The study concludes with recommendations on how to improve the general conditions concerning telework.
