Approximation by harmonic polynomials in star-shaped domains and exponential convergence of Trefftz hp-DGFEM
(2012)SAM Research ReportWe study the approximation of harmonic functions by means of harmonic polynomials in twodimensional, bounded, star-shaped domains. Assuming that the functions possess analytic extensions to a $\delta$-neighbourhood of the domain, we prove exponential convergence of the approximation error with respect to the degree of the approximating harmonic polynomial. All the constants appearing in the bounds are explicit and depend only on the ...Report -
Sparse, adaptive Smolyak algorithms for Bayesian inverse problems
(2012)SAM Research ReportBased on the parametric deterministic formulation of Bayesian inverse problems with unknown input parameter from infinite dimensional, separable Banach spaces proposed in [28], we develop a practical computational algorithm whose convergence rates are provably higher than those of Monte-Carlo (MC) and Markov-Chain Monte-Carlo methods, in terms of the number of solutions of the forward problem. In the formulation of [28], the forward ...Report -
Exploration or Exploitation of Knowledge from Universities
(2012)KOF Working PapersIn a first step, we developed based on existing theoretical and empirical literature a series of hypotheses with respect to the relative importance of possible determinants of exploration and exploitation of knowledge in collaboration with universities and tested them on Swiss firm data. In a second step, we investigated the impact on innovation performance of knowledge exploration versus knowledge exploitation. We obtained a clear pattern ...Working Paper -

Assessing the impact of support policies for energy efficient technology in Switzerland
(2012)KOF Working PapersThis study uses data of a representative sample of Swiss rms to assess the effectiveness of policy measures directed at the diusion of energy ecient technology (EET). Three different outcome variables (number of EET applications implemented, CO2 reduction, and EET related investment) are analysed using methods based on the estimated propensity score in an attempt to overcome the problem of non-random assignment. I conclude that, even after ...Working Paper -
A real time evaluation of employment forecasts in Switzerland
(2012)KOF Working PapersWe evaluate nowcasts and one- to four-quarter-ahead forecasts of Swiss full time equivalent jobs from 1998q1–2011q4, comparing forecasts of the KOF Swiss Economic Institute and of the State Secretariat for Economic Affairs with the outcome of the reference series. Both forecasts are biased downward, and they do not capture the trend of the reference series well. In addition, we show that the KOF Employment Indicator as well as the Employment ...Working Paper -
Does the oil price adjust optimally to oil field discoveries?
(2012)Economics Working Paper SeriesThe Hotelling rule argues that the price for a non-renewable resource adjusts to the shadow value of the resource, reflecting its remaining availability. This study provides an empirical test of this hypothesis. It investigates whether the price of crude oil does adjust to unexpected news about oil field discoveries. The observed price reaction is compared with a prediction of the price decline as derived from the Hotelling model. This ...Working Paper -
Das Personenfreizügigkeitsabkommen Schweiz-EU / EFTA und das Wachstum des BIP pro Kopf in der Schweiz
(2012)KOF StudiesDieser Bericht beleuchtet, wie das Personenfreizügigkeitsabkommen (FZA) der Schweiz mit den EU/EFTA-Staaten das Einkommenswachstum in der Schweiz in den letzten Jahren beeinflusst hat. Der Bericht verfolgt das Ziel, Klarheit in die in der Öffentlichkeit teils widersprüchlich geführte Debatte zu bringen, ob die Auswirkungen des FZA auf das Einkommenswachstum nun positiv oder negativ seien. Es werden dabei insbesondere die Auswirkungen ...Report -
