First Order Methods For Distributed Control: Unique Stationarity Beyond Quadratic Invariance
(2019)We study the distributed Linear Quadratic Gaussian (LQG) control problem in finite-horizon, where the controller depends linearly on the history of the outputs and it is required to possess a given sparsity pattern. It is well-known that a convex formulation of this problem in terms of disturbance-feedback control policies is only possible when a condition known as Quadratic Invariance (QI) holds. In this paper, we first show that given ...Working Paper -
Neural Importance Sampling
(2019)We propose to use deep neural networks for generating samples in Monte Carlo integration. Our work is based on non-linear independent components estimation (NICE), which we extend in numerous ways to improve performance and enable its application to integration problems. First, we introduce piecewise-polynomial coupling transforms that greatly increase the modeling power of individual coupling layers. Second, we propose to preprocess ...Working Paper -
Valuable experience: How internships affect university graduates’ income
(2019)KOF Working PapersThis paper analyzes whether and how attending an internship during tertiary education affects income. We address endogeneity with an IV approach that exploits information regarding whether the internship was a mandatory component of the study. We further address selection into programs with mandatory internship by using the share of mandatory internships at the closest university, exploiting the low mobility of Swiss students. The results ...Working Paper -
Capturing network properties with a functional form for the multi-modal macroscopic fundamental diagram
(2019)Arbeitsberichte Verkehrs- und RaumplanungIn urban road networks, the interactions between different modes can clearly impact the overall travel production. Although those interactions can be quantified with the multi-modal macroscopic fundamental diagram; so far, no functional form exists for this diagram to explicitly capture operational and network properties. In this paper, we propose a methodology to generate such functional form, and we show its applicability to the specific ...Working Paper -
A general framework for multi-modal macroscopic fundamental diagrams (MFD)
(2019)Arbeitsberichte Verkehrs- und RaumplanungCar traffic streams in urban networks are rarely homogeneous and usually contain some disturbances by other transport modes of different physical characteristics, e.g. bicycles or buses. Inevitably, these interactions decrease the network’s capacity and performance, but, so far, no methodology exists to assess the local interaction effects on the network level as for instance described in the macroscopic fundamental diagram (MFD). This ...Working Paper -

Subsidized ridesourcing for the first/last mile: How valuable for whom?
(2019)Arbeitsberichte Verkehrs- und RaumplanungMany transit agencies partner with ridesourcing companies to offer subsidized first/last mile services. Ridership, however, has been low in many cases. Complementing popular operational explanations for low ridership, we explore two conceptual ones: using ridesourcing for the first/last mile adds an additional transfer and costs to the overall transit trip. We quantify both hypotheses simulating commuting trips in three structurally ...Working Paper
