"Does Choice Change Preferences? An Incentivized Test of the Mere Choice Effect", Experimental Economics.
Abstract
Widespread evidence from psychology and neuroscience documents that previous choices unconditionally increase the later desirability of chosen objects, even if those choices were uninformative. This is problematic for economists who use choice data to estimate latent preferences, demand functions, and social welfare. The
evidence on this mere choice efect, however, exhibits serious shortcomings which prevent evaluating its possible relevance for economics. In this paper, we present
a novel, parsimonious experimental design to test for the economic validity of the mere choice efect addressing these shortcomings. Our design uses well-defned,
monetary lotteries, all decisions are incentivized, and we efectively randomize participants’ initial choices without relying on deception. Results from a large, preregistered online experiment fnd no support for the mere choice efect. Our results challenge conventional wisdom outside economics. The mere choice efect does not seem to be a concern for economics, at least in the domain of decision making under risk.

Replication Data for: Spatial Voting Meets Spatial Policy Positions: An Experimental Appraisal
No full textWe develop and validate a novel experimental design that builds a bridge between experimental research on the theory of spatial voting and the literature on measuring policy positions from text. Our design utilizes established text-scaling techniques and their corresponding coding schemes to communicate candidates’ numerical policy positions via verbal policy statements. This design allows researchers to investigate the relationship between candidates’ policy stances and voter choice in a purely text-based context. We validate our approach with an online survey experiment. Our results generalize previous findings in the literature and show that proximity considerations are empirically prevalent in purely text-based issue framing scenarios. The design we develop is broad and portable, and we discuss how it adds to current experimental designs, as well as suggest several implications and possible routes for future research

Incentives in Surveys, accepted for publication in the Journal of Economic Psychology.
Abstract: Surveys typically use hypothetical questions to measure subjective and unverifiable concepts like happiness and quality of life. We test whether this is problematic using a large survey experiment on health and subjective well-being. We use Prelec’s Bayesian truth serum to incentivize the experiment and defaults to introduce biases in responses. Without defaults, the data quality was good and incentives had no impact. With defaults, incentives reduced biases in the subjective well-being questions by inducing participants to spend more effort. Incentives had no impact on the health questions regardless of whether defaults were used.</p

Georg Hermann.
No full textThe internationally renowned author of numerous novels, essays, and articles, Georg Hermann, was born as Georg Borchardt in Berlin-Friedenau on October 7, 1871, the youngest of six children in a well-established Jewish family. Later in life he used his father’s first name Hermann as his surname when writing. Contrary to the expectations for a young man from a reputable family, Hermann did not pursue the Abitur exam in a Gymnasium (secondary school), but instead received a one-year certificate in 1890, leaving school to become an apprentice salesman at a tie company. From 1896 until 1899 he worked in the Statistical Office of Berlin, at the same time attending literature and art history lectures at the University of Berlin. Afterwards he worked as a freelance writer and art critic.His first book, 'Spielkinder', was published in 1896, but he did not become well-known until 1906, with the publication of 'Jettchen Gebert', followed by its sequel, 'Henriette Jacoby'. These novels told the story of the life of a young woman living in Jewish Berlin during the Biedermeier period of the 1820s and 1830s. Politically active, Georg Hermann was also a member of the Central-Verein deutscher Staatsbürger jüdischen Glaubens.Having become known for his pacifist tendencies through his writing, and because of his Jewish heritage, Georg Hermann and his family fled to Holland shortly after the burning of the Reichstag in 1933. Although the rest of his family was saved from the Nazis after their occupation of Holland in 1943, Georg Hermann was sent to the Dutch concentration camp of Westerbork. On November 16, 1943 he was transported to Auschwitz and either died during transport or shortly after his arrival.Digital ImageRecord added to DigiTool. Aleph record suppressed. J.

Reward-dependent dynamics and changes in risk taking in the Balloon Analogue Risk Task
Get PDFThe Balloon Analogue Risk Task (BART) assesses real-world decision-making processes in a laboratory setting and has been applied to both healthy and clinical populations. Whereas many previous studies established reliable links between behaviour in the BART and individual characteristics, such as gender, age, and educational level, little is known to date how dynamic, contextual features of the BART impact risk taking behaviour. The present paper fills this gap and reports the results of an online BART administered to a sample of 141 voluntary participants. Taking a novel, single-trial perspective, we document significant associations between experience and expectation related variables, in particular reward and punishment dynamics, and risk-taking behaviour in the BART. Having accrued more money increases risk-taking behaviour as does experiencing foregone profits through exploded balloons. Our findings are consistent with prominent theories of decision-making under risk which postulate intra-person changes in risk-appetite. Our results have important implications for future research as they stress that a more dynamic perspective on the BART can enrich our understanding of the factors that shape risk-taking behaviour
Georg Trakl and melancholy
No full textThis paper identifies some of the decisive aspects of Georg Trakl’s poetry, taking as the starting point the author’s awareness about God’s death, from Nietzsche’s approach. Emphasis is placed on melancholy, support of the creation, testimony and acknowledgement of failure and grief of mankind, from which the author was able to express his discouragement upon the downfall and decline of the West.Se identificaron algunos aspectos determinantes de la obra poética de Georg Trakl, tomando como punto de partida la conciencia del escritor acerca de la muerte de Dios, desde la perspectiva de Nietzsche. Se hizo un énfasis sobre la melancolía, soporte de la creación, testimonio y reconocimiento del errar y el duelo del hombre, a partir de la cual el autor pudo expresar el desconsuelo por la ruina y el ocaso de Occidente
