Solving the incomplete markets model in parallel using GPU computing and the Krusell–Smith algorithm
No full textThis paper demonstrates the potential of graphics processing units in solving the incomplete markets model in parallel using the Krusell–Smith algorithm. We illustrate the power of this approach using the same exercise as in Den Haan et al. (J Econ Dyn Control 34:1–3, 2010). We document a speed gain which increases sharply with the number of agents. To reduce entry barriers, we explain our methodology and provide some example algorithms

La duquesa Hadwig de Suabia a través de la novela histórica alemana "Ekkehard" de Joseph Victor von Scheffel
No full textEl objetivo de este artículo es presentar el retrato de la duquesa Hadwig de Suabia, que aun siendo una de las mujeres intelectuales más importantes del Renacimiento otoniano de Alemania, es prácticamente desconocida en España. El retrato además se hará a través de la descripción que realiza de ella el autor alemán Joseph Victor von Scheffel en su novela histórica Ekkehard. Eine Geschichte aus dem 10. Jahrhundert (1855). Hay constancia de Hadwig en fuentes literarias medievales que posteriormente fueron rescatadas en el siglo xix por Scheffel y que él documenta exhaustivamente en su libro, esbozando una semblanza tan detallada de la época y de esta mujer, que aun siendo un texto literario y que por tanto contiene elementos ficticios, no deja de ser un testimonio interesante digno de ser estudiado.The aim of this paper is to present a portrait of the duchess Hadwig of Swabia, who in spite of being one of the most important intellectual women of the Ottonian Renaissance in Germany, is practically unknown in Spain. This portrait is based on the description that the German author Joseph Victor von Scheffel writes in his historical novel Ekkehard. Eine Geschichte aus dem 10. Jahrhundert (1855). Some literary medieval resources speak of Hadwig, and they were later used by Scheffel in the 19th century. He documents them in a very exhaustive way in his novel and achieves such a detailed view of this period and this woman that, although the text is a literary text and therefore contains some fiction, it is an interesting evidence that it is worth studying.Filologí
Consumption velocity in a cash costly-credit model
No full textIn a seminal study Hodrick et al. (1991) evaluate the ability of a simple cash-credit model to produce realistic variability in consumption velocity while at the same time successfully explaining other key statistics. Sufficient variability in the latter is found to be associated with far too volatile interest rate behaviour. Introducing habit-formation in consumption into a production-based cash costly-credit model (see Gillman and Benk, 2007) makes the evolution of deposits more rigid relative to credit. The same deposit rigidity leads to a more volatile price of credit, causing credit production overshooting relative to deposits. But only by introducing adjustment costs to investment in addition to habit persistence does credit production overshoot sufficiently to produce realistic variability in consumption velocity. The model succeeds in capturing sufficient variability in consumption velocity without obtaining too volatile interest rates. Also, this model of endogenous velocity does not suffer from indeterminacy problems discussed in Auray et al. (2005). In contrast to Gillman and Benk (2007), the present study examines the role of the price-channel of credit production at business cycle frequency, ignoring or holding fixed the marginal cost channel stemming from credit productivity shocks
Concept Focus: Semantic Meta-Data For Describing MOOC Content
No full textMOOCs promised to herald a new age of open education.However, efficient access to MOOC content is still hard, thus unneces-sarily complicating many use cases like efficient re-use of material, ortailored access for life-long learning scenarios. One of the reasons for thislack of accessibility is the shortage of meaningful semantic meta-data de-scribing MOOC content and the resulting learning experience. In this pa-per, we explore Concept Focus, a new type of meta-data for describing aperceptual facet of modern video-based MOOCs, capturing how focuseda learning resource is topic-wise, which is often an indicator of clarityand understandability. We provide the theoretical foundations of Con-cept Focus and outline a methodical workflow of how to automaticallycompute it for MOOC lectures. Furthermore, we show that the learners’consumption behavior is correlated with a MOOC lecture’s Concept Focus, thus underlining that this type of meta-data is indeed relevant for user-centric querying, personalizing or even designing the MOOC experience. For showing this, we performed an extensive study with real-lifeMOOCs and 12,849 learners over the duration of three months.Green Open Access added to TU Delft Institutional Repository ‘You share, we take care!’ – Taverne project https://www.openaccess.nl/en/you-share-we-take-care Otherwise as indicated in the copyright section: the publisher is the copyright holder of this work and the author uses the Dutch legislation to make this work public.Web Information System
SRLx: A Personalized Learner Interface for MOOCs
No full textPast research in large-scale learning environments has found one of the most inhibiting factors to learners’ success to be their inability to effectively self-regulate their learning efforts. In traditional small-scale learning environments, personalized feedback (on progress, content, behavior, etc.) has been found to be an effective solution to this issue, but it has not yet widely been evaluated at scale. In this paper we present the Personalized SRL Support System (SRLx), an interactive widget that we designed and open-sourced to improve learners’ self-regulated learning behavior in the Massive Open Online Course platform edX. SRLx enables learners to plan their learning on a weekly basis and view real-time feedback on the realization of those plans. We deployed SRLx in a renewable energies MOOC to more than 2,900 active learners and performed an exploratory analysis on our learners’ SRL behavior.Green Open Access added to TU Delft Institutional Repository ‘You share, we take care!’ – Taverne project https://www.openaccess.nl/en/you-share-we-take-care Otherwise as indicated in the copyright section: the publisher is the copyright holder of this work and the author uses the Dutch legislation to make this work public.Web Information System
A Credit-Banking Explanation of the Equity Premium, Term Premium, and Risk-Free Rate Puzzles
No full textMicro-founded de-centralized financial intermediation in a cash and costly-credit model (see Gillmand and Kejak, 2008) results in a cost-distortion of returns implying a lower average nominal and real risk-free rate when compared to standard cah-in-advance RBC models. Failure of both short-run and long-run Fisher equation relationships based on observable real and nominal rates and inflation are obtained. The cost-distortion also leads to an unconditionally upward-sloping average yield curve of interest rates which is also convex in shape. The model is capable of producing a positive correlation between the nominal rate and velocity, and a negative correlation between the ex-post real rate and inflation. More importantly, the model also predicts a negative correlation between the ex-ante real rate and the ex-ante expected rate of inflation. Finally, the condition spread between the usual CCAPM rate as defined by Canzoneri and Diba (2005) and the model-implied money market rate is positively correlated with the stance of monetary policy, offering a new perspective on this systematic link recently studied empirically by Canzoneri et al. (2007a) and theoretically by Canzoneri and Diba (2005).Business cycles; Money; Term structure of interest rates

Wege zu einer genetischen Narratologie oder. Von der Geburt und dem Abenteuer der Geschichten am Beispiel von Werkgenesen des Autors Arthur Schnitzler
No full textOver the course of the so-called narrative turn, narrative research has fundamentally expanded its scope and now also shows an interest in, among other things, the pragmatic context of narratives. As a result of the ‘cognitive turn’, narratologists have mainly explored the ways in which narratives are perceived and received.
Yet every narrative also involves a production process, a crucial dynamic which should also be of narratological interest. This article draws attention to this particular gap in narrative research and tries to reduce it by examining an exemplary case as well as proposing some theoretical considerations towards a genetic narratology. Drawing on the formalist-structuralist model of ‘narrative constitution’ and the phenomenological concept of a ‘narrative hermeneutics,’ it introduces a new methodological approach which seeks to combine research questions and terminologies from the fields of edition philology and narrative theory. The approach will be illustrated with reference to the author Arthur Schnitzler, by investigating his working methods as well as the genesis of his narrative works over several decades. In this context the article particularly focuses on the ‘monologue novella’ Fräulein Else, which – albeit completed in the 1920’s and published in 1924 – probably traces back to a note from the 1890’s
