And Action: TV Sentiment and the US Consumer
(2010)KOF Working PapersThe average American watches over five hours of television per day. We test whether sentiment in TV news shows influences the ordinary consumer in the US, and whether the University of Michigan Index of Consumer Sentiment is better at explaining changes in private consumption than TV news sentiment. TV news sentiment, we find, can better explain the consumption behavior of US households, especially when combined with personal income and savings.Working Paper -
From Rags to Riches: How Robust is the Influence of Culture on Entrepreneurial Activity?
(2010)KOF Working PapersEntrepreneurial activity differs substantially across countries. While cultural differences across countries have often been proposed as an explanation, measuring a country's cultural characteristics suffers from various problems. This paper offers new evidence on the relative importance of cultural and institutional determinants of economic activity. In order to test the hypothesis that cultural factors influence entrepreneurial behavior, ...Working Paper -
The information content of capacity utilisation rates for output gap estimates
(2010)KOF Working PapersFrom a theoretical perspective, the output gap is probably the most comprehensive and convincing concept to describe the cyclical position of an economy. Unfortunately, for practical purposes, the concept depends on the determination of potential output, which is an inherently unobservable variable. In this paper, we examine whether the real-time estimates of the output gap as published by the OECD can be improved by referring to measures ...Working Paper -
The VisuLab
(2010)Technical Report / ETH Zurich, Department of Computer ScienceTeaching experiences made at ETH Zurich support the idea that multivariate data visualization – a powerful tool for Exploratory Data Analysis – can be used as a medium to teach many information processing competencies. Particularly interactive comparative visualization, an approach that allows the graphical manipulation of data in several different displays simultaneously, can engage students in interesting problems to actively manipulate ...Report -
Computer-basierte high-stake Leistungskontrolle mit Sioux
(2010)Technical ReportSeit 10 Jahren unterrichtet das Departement Informatik der ETH Zürich rund 600 Studierende der Naturwissenschaften in Informatik computergestützt. Diese Lehrveranstaltungen werden im Rahmen von Semesterendprüfungen oder Sessionsprüfungen benotet. Zudem werden formative Lernerfolgskontrollen eingesetzt, um den Lernerfolg zu verfolgen und zu erhöhen. Zur Effizienz- und Effektivitätssteigerung führen wir seit 2004 diese unbenoteten, formativen ...Report -
Sparse Tensor Approximation of Parametric Eigenvalue Problems
(2010)SAM Research ReportWe design and analyze algorithms for the efficient sensitivity computation of eigenpairs of parametric elliptic self-adjoint eigenvalue problems on high-dimensional parameter spaces. We quantify the analytic dependence of eigenpairs on the parameters. For the efficient approximate evaluation of parameter sensitivities of isolated eigenpairs on the entire parameter space we propose and analyze a sparse tensor spectral collocation method ...Report -
