Agnostic Output Gap Estimation and Decomposition in Large Cross-Sections
(2019)This paper uses a Bayesian non-stationary dynamic factor model to extract common trends and cycles from large datasets. An important but neglected feature of Bayesian statistics allows to treat stationary and non-stationary time series equally in terms of parameter estimation. Based on this feature we show how to extract common trends and cycles from the data by ex-post processing the posterior output and describe how to derive an ...Working Paper -

The “Forgotten” Middle Class: An Analysis of the Effects of Globalisation
(2019)KOF Working PapersThis paper studies the effects of globalisation on the income share of the middle class. Our findings suggest that globalisation, proxied by the KOF Economic Globalisation Index, reduces the income share of the middle class. The income share of the poorest 20% also drops due to globalisation, while that of the richest 20% increases. When we distinguish between de facto and de jure globalisation, we find that only de facto measures have ...Working Paper -

The Effects of Economic Globalisation and Ethnic Fractionalisation on Redistribution
(2019)KOF Working PapersWe examine the effect of economic globalisation on income redistribution and hypothesise that it depends on ethnic fractionalisation. In highly fractionalised countries, powerful ethnicities are able to extract globalisation-induced benefits, whereas their governments face substantial political obstacles when redistributing income between ethnic groups. Using the newly constructed KOF Globalisation Index, we find supportive evidence for ...Working Paper -

Twenty Key Questions in Environmental and Resource Economics
(2019)Economics Working Paper SeriesEconomic and ecological systems are closely interlinked at a global and a regional level, offering a broad variety of challenging research topics in environ- mental and resource economics. The successful identification of key questions for current and future research supports development of novel theories, empirical applications, and appropriate policy designs. It allows establishing a future- oriented research agenda whose ultimate ...Working Paper -
Strong structural controllability under network perturbations
(2019)arXivThis paper investigates the robustness of strong structural controllability for linear time-invariant and linear time-varying directed networks with respect to structural perturbations, including edge deletions and additions. In this direction, we introduce a new construct referred to as a perfect graph associated with a network with a given set of control nodes. The tight upper bounds on the number of edges that can be added to, or removed ...Working Paper -
Laplacian dynamics on cographs
(2018)arXivIn this paper, we examine the controllability of Laplacian dynamic networks on cographs. Cographs appear in modeling a wide range of networks and include as special instances, the threshold graphs. In this work, we present necessary and sufficient conditions for the controllability of cographs, and provide an efficient method for selecting a minimal set of input nodes from which the network is controllable. In particular, we define a ...Working Paper -
Today me, tomorrow thee
(2019)arXivWe present a new type of coordination mechanism among multiple agents for the allocation of a finite resource, such as the allocation of time slots for passing an intersection. We consider the setting where we associate one counter to each agent, which we call karma value, and where there is an established mechanism to decide resource allocation based on agents exchanging karma. The idea is that agents might be inclined to pass on using ...Working Paper -
Stability analysis of fractional order systems described in the Lur'e structure
(2015)arXivLur'e systems are feedback interconnection of a linear time-invariant subsystem in the forward path and a memoryless nonlinear one in the feedback path, which have many physical representatives. In this paper, some classical theorems about the L2 input-output stability of integer order Lur'e systems are discussed, and the conditions under which these theorems can be applied in fractional order Lur'e systems with an order between 0 and 1 ...Working Paper -
Strong structural controllability of signed networks
(2019)arXivIn this paper, we discuss the controllability of a family of linear time-invariant (LTI) networks defined on a signed graph. In this direction, we introduce the notion of positive and negative signed zero forcing sets for the controllability analysis of positive and negative eigenvalues of system matrices with the same sign pattern. A sufficient combinatorial condition that ensures the strong structural controllability of signed networks ...Working Paper -
Low-energy electron escape from liquid interfaces: charge and quantum effects
(2019)arXivThe high surface sensitivity and controlled surface charge state of submicron sized droplets is exploited to study low-energy electron transport through liquid interfaces using photoelectron imaging. Already a few charges on a droplet are found to modify the photoelectron images significantly. For narrow escape barriers, the comparison with an electron scattering model reveals pronounced quantum effects in the form of above-barrier ...Working Paper -
The Fictional Addressee of Architecture as a Device for Exploring Post-colonial Culture: The Transformations of the Helleno-centric Approaches
(2019)This postdoctoral research project examines the relationships between architecture’s epistemology within the Greek and international contexts, scrutinizing their interdependences. It is focused on the analysis of three case studies: the travels to Greece of the Villa Medici pensionnaires in the 19th century, the trajectories of the architects of Mataroa, and the different approaches of bridging Helleno-centricism and modernism within the ...Working Paper -
Learning from the MaaS experience in Augsburg, Germany
(2019)Arbeitsberichte Verkehrs- und RaumplanungRecent technological advances have led to a surge of new shared transportation modes. This development has inspired the concept ‘Mobility as a Service’ (MaaS), which seeks to integrate the emerging shared modes with conventional public transportation. Enabled by this development, multimodal mobility plans (i.e., mobile phone plans for mobility) have become a topic of particular interest both for transportation scholars and practitioners ...Working Paper
