Trend Fundamentals and Exchange Rate Dynamics
(2015)KOF Working PapersWe estimate a multivariate unobserved components-stochastic volatility model to explain the dynamics of a panel of six exchange rates against the US Dollar. The empirical model is based on the assumption that both countries' monetary policy strategies may be well described by Taylor rules with a time-varying inflation target, a time-varying natural rate of unemployment, and interest rate smoothing. The estimates closely track major movements ...Working Paper -
Endogenous persistence with recursive inattentiveness
(2011)KOF Working PapersThe DSGE model with endogenous and time-varying sticky information in Dräger (2010) is extended by allowing agents’ recursive choice between forecasts under rational or sticky information to affect the model solution. Dynamic equilibrium paths generate highly persistent series for output, inflation and the nominal interest rate. Agents choose predictors in a near-rational manner and we find that the share of agents with rational expectations ...Working Paper -
Subdivision shell elements with anisotropic growth
(2012)ArXivA thin shell finite element approach based on Loop's subdivision surfaces is proposed, capable of dealing with large deformations and anisotropic growth. To this end, the Kirchhoff-Love theory of thin shells is derived and extended to allow for arbitrary in-plane growth. The simplicity and computational efficiency of the subdivision thin shell elements is outstanding, which is demonstrated on a few standard loading benchmarks. With this ...Working Paper -
Commuting distance and individual accessibility
(2018)Arbeitsberichte Verkehrs- und RaumplanungIn the present study a methodology to construct individual-based accessibility measures is introduced. Building on the concept of specifying the distance decay function as a survival function, the transition from a data-driven approach for aggregate distance decay functions, to a model- based approach for individual-based ones is presented. Based on this, the construction of location- and person-specific accessibility measures is facilitated, ...Working Paper -
Within-day replanning of exceptional events
(2011)Arbeitsberichte Verkehrs- und RaumplanungTypical software that is used for the simulation of traffic behavior focuses on scenarios that describe common situations like an ordinary working day without remarkable incidents. To simulate such scenarios, iterative approaches are used. They assume that the simulated people adapt to the results of the previous iterations. Such iterative approaches produce meaningful results for various scenarios as long as only typical, repetitive ...Working Paper -
Modeling household fleet choice as a function of fuel price using a multiple discrete-continuous choice model
(2011)Arbeitsberichte Verkehrs- und RaumplanungIn this Paper, a new model of fleet choice for households is presented that uses the multiple discrete-continuous extreme value (MDCEV) model as a framework. The aim of the model is to establish a model to allocate car types to activity based microscopic agent based transport simulations. What is new in the presented model, is that in addition to socioeconomic attributes of households, the choice is also influenced by fuel price. To model ...Working Paper -

Impact of bicycle traffic on the macroscopic fundamental diagram
(2019)Arbeitsberichte Verkehrs- und RaumplanungInteractions between bicycles and cars have begun to attract increasing attention. This paper aims to investigate network-level car-bicycle interactions by quantifying the impact of bicycle traffic on empirical macroscopic fundamental diagrams (MFDs). First, the stratified re-sampling method is used to analyze the impact of bicycle-related facilities on network capacity and critical density. Then, the trapezoidal MFD function is applied ...Working Paper -
Understanding Travel and Mode Choice with Emerging Modes
(2019)Arbeitsberichte Verkehrs- und RaumplanungResearch presented in this paper analyzed two data sets from Revealed Preference (RP) and Stated Preference (SP), obtained with a new travel diary and mode choice survey. This survey, called Mobility Jakarta, combines both revealed and stated preference parts and was conducted in the Greater Jakarta region. This is the first survey that collected responses from a substantial sample of the population across the whole metropolitan area. We ...Working Paper -
Impact of major road supply on individual travel time expenditure
(2017)Arbeitsberichte Verkehrs- und RaumplanungThis study estimates the impact of major road supply on individual travel time expenditure (TTE) using data on 30-year changes in transportation infrastructure and travel behavior. The impact observed shortly after the improvement to the road infrastructure is estimated from a data set that combines records on large-scale household travel surveys in the Tokyo metropolitan area conducted in 1978, 1988, 1998, and 2008. Linear and Tobit ...Working Paper
