 Adrian Bachmann, Indoornavigation mittels Ortsinterpolation, University of Zurich, Faculty of Economics, Business Administration and Information Technology, 2006. (Master's Thesis)
Satellite navigation is ubiquitous in our daily life. Unfortunately, satellite navigation signals can not be received somtimes. Due to this effect, a new stream of reseach has been emerged focussing on alternatives, especially in the area of indoor-navigation. In this diploma thesis a new approach is developed and presented. The new approach induces in a new way navigation information from accelerometer and magnetometer sensor data. The new approach overcomes the shortcoming of insufficient calibration - one of the major issues in current research. The main contribution of this work is an online calibration framework, which allows to adapt to changing border conditions. Thus, the result is a much more robust, precise, and up-to-date base for the path extrapolation. |

Sascha O Becker, Mathias Hoffmann, Intra- and international risk-sharing in the short run and the long run, European Economic Review, Vol. 50 (3), 2006. (Journal Article)
We investigate empirically how industrialized countries and US states share consumption risk at horizons between 1 and 30 years. US federal states share about 50% of their permanent idiosyncratic risk through cross-state capital income flows. While insurance against transitory fluctuations in output is virtually complete, OECD countries do not share any of their permanent idiosyncratic risk. Our results suggest that purely transaction cost based theories cannot explain the home bias, since the potential welfare gains from insurance against permanent shocks would by far outweigh that of insuring against transitory variation. We conclude that permanent and transitory shocks constitute two qualitatively different kinds of risk and that various forms of endogenous market incompleteness may render permanent shocks a lot harder to insure, in particular at the international level. |

Pavlo R Blavatskyy, Axiomatization of a preference for most probable winner, Theory and Decision, Vol. 60 (1), 2006. (Journal Article)
In binary choice between discrete outcome lotteries, an individual may prefer lottery L1 to lottery L2 when the probability that L1 delivers a better outcome than L2 is higher than the probability that L2 delivers a better outcome than L1. Such a preference can be rationalized by three standard axioms (solvability, convexity and symmetry) and one less standard axiom (a fanning-in). A preference for the most probable winner can be represented by a skew-symmetric bilinear utility function. Such a utility function has the structure of a regret theory when lottery outcomes are perceived as ordinal and the assumption of regret aversion is replaced with a preference for a win. The empirical evidence supporting the proposed system of axioms is discussed. |

Joseph P Romano, Michael Wolf, Improved nonparametric confidence intervals in time series regressions, Journal of Nonparametric Statistics, Vol. 18 (2), 2006. (Journal Article)
Confidence intervals in econometric time series regressions suffer from notorious coverage problems. This is especially true when the dependence in the data is noticeable and sample sizes are small to moderate, as is often the case in empirical studies. This article suggests using the studentized block bootstrap and discusses practical issues such as the choice of the block size. A particular data-dependent method is proposed to automate the method. As a side note, it is pointed out that symmetric confidence intervals are preferred over equal-tailed ones, as they exhibit improved coverage accuracy. The improvements in small sample performance are supported by a simulation study. |

Thomas Reutterer, Andreas Mild, Martin Natter, Alfred Taudes, A dynamic segmentation approach for targeting and customizing direct marketing campaigns, Journal of Interactive Marketing, Vol. 20 (3/4), 2006. (Journal Article)
An important aspect of customer relationship management is the targeting of customer segments with tailored promotional activities. While most contributions focus on the selection of promising customers for targeting, only few authors address the question of which specific differential offers to direct to the selected target groups. We focus on both issues and propose a flexible, two-stage approach for dynamically deriving behaviorally persistent segments and subsequent target marketing selection using retail-purchase histories from loyalty-program members. The underlying concept of behavioral persistence entails an in-depth analysis of complementary cross-category purchase interdependencies at a segment level. The effectiveness and efficiency of the proposed procedure are demonstrated in a controlled field experiment involving the targeting of several thousands of customers enrolled in the loyalty program of a “do-it-yourself” retailer. Our empirical findings provide evidence of significant positive impacts on both profitability and sales for segment-specific tailored direct marketing campaigns. |
