A Reconsideration of the Stiglitz-Weiss Model with a Discrete Number of Borrower Types
No full textIn this paper we show that the equilibrium in the Stiglitz-Weiss model (Stiglitz and Weiss, 1981) is a two-interest rate equilibrium. For this we use the true return-function for banks shown by Arnold (2005), the assumption of Bertrand competition and make a consideration for a discrete number of borrowers. Rationing only affects one group of the borrowers, i.e. the borrowers with a safe project. The risky group always receives the funds it demands.credit rationing, asymmetric information, adverse selection
Codebook and documentation of the panel study 'Labour Market and Social Security' (PASS) : Volume I: Introduction and overview. Wave 2 (2007/2008)
No full text"The panel study 'Labour Market and Social Security' (PASS), established by the Institute for Employment Research (IAB), is a new dataset for labour market, welfare state and poverty research in Germany, creating a new empirical basis for the scientific community and for policy advice. This Datenreport provides an overview of the second survey wave, for which 12,487 individuals were interviewed in 8,429 households between December 2007 and July 2008. 10,114 individuals and 7,342 households were interviewed for the second time in the context of PASS. The spectrum of questions and the design of PASS are intended to close gaps in the existing stock of data. PASS has three main characteristics that extend analysis potential beyond that of the Federal Employment Agency's administrative data: 1. The panel takes the household context into account - including the situation before and after receipt of Unemployment Benefit II. 2. The panel is complete in that it covers all groups of persons and all employment biographies, not only people in dependent employment, unemployed people and those in need of assistance. The dataset also provides information on the status during phases of economic inactivity, self-employment or employment as civil servants. 3. The panel collects additional or significantly more detailed data on relevant characteristics such as attitudes, employment potential or job-search behaviour."

Loan origination under soft- and hard-information lending : [Version: August 2008]
No full textThis paper presents a novel model of the lending process that takes into account that loan officers must spend time and effort to originate new loans. Besides generating predictions on loan officers’ compensation and its interaction with the loan review process, the model sheds light on why competition could lead to excessively low lending standards. We also show how more intense competition may fasten the adoption of credit scoring. More generally, hard-information lending techniques such as credit scoring allow to give loan officers high-powered incentives without compromising the integrity and quality of the loan approval process. The model is finally applied to study the implications of loan sales on the adopted lending process and lending standard
Single-Name Credit Risk, Portfolio Risk, and Credit Rationing
No full textThis paper introduces non-diversifiable risk in the Stiglitz-Weiss adverse selection model, so that an increase in the average riskiness of the borrower pool causes higher portfolio risk. This opens up the possibility of equilibrium credit rationing. Comparative statics analysis shows that an increase in risk aversion turns a two-price equilibrium into a rationing equilibrium. A two-price equilibrium is more inefficient than a rationing equilibrium, and a usury law that rules out the higher of the two interest rates can be welfare-improving. Contrary to the common result, the equilibrium may be characterized by over-investment.asymmetric information; credit rationing
"Irresponsible lending" with a better informed lender
No full textWe present a simple model of personal finance in which an incumbent lender has an information advantage vis-a-vis both potential competitors and households. In order to extract more consumer surplus, a lender with sufficient market power may engage in "irresponsible"lending, approving credit even if this is knowingly against a household’s best interest. Unless rival lenders are equally well informed, competition may reduce welfare. This holds, in particular, if less informed rivals can free ride on the incumbent’s superior screening ability
Knowledge workers & knowledge utilization. Professionalizing interchange of knowledge between practice and science
No full textHessler G, Micheel H-G, Unzicker K. Knowledge workers & knowledge utilization. Professionalizing interchange of knowledge between practice and science.; 2005.In the era of "Knowledge Societies" innovations and expertise are often called the most important resources (Daniel Bell; Peter Drucker) especially for organizations, and the knowledge worker becomes a famous object of sociological research (e.g. Helmut Willke). In theories of organizational learning (e.g. Agyris and Schön) the individual actor and his attitudes aren't in the focus of interest. Here we will present a qualitative research on practitioners from different professions and their use of and attitudes towards scientific knowledge and their interaction with research establishments or scientists. We interviewed more than 50 professionals with different academic backgrounds in different organizations. They were asked, how they search for and use scientific information or knowledge, how they proof it and how important this information input is for their personal work and for the organization. Two major findings are: (1) a specific science orientation - attitude among most interview partners and (2) a change from educated knowledge to informed knowledge (Nina Degele)
Radiolytic Production of Fluorine Gas from MSR Relevant Fluoride Salts
No full textRadiolytic fluorine gas production at temperatures of 40°C to 60°C was investigated for the fluoride salts LiF, BeF2, UF4, ThF4, and 71.7LiF-16BeF2-12.3UF4 (FliBe-UF4) by gamma irradiation of powdered samples using spent fuel elements from the High Flux Reactor (HFR) Petten as the irradiation source; work of a similar nature was previously performed at Oak Ridge National Laboratory in the period 1965 to 1995. Gamma irradiation was conducted for just over 41 days, with total absorbed gamma dose ranging from ~45 MGy for the lightest salts to ~170 MGy for ThF4 and UF4. By measuring the gas pressure within salt-filled capsules during irradiation, it was possible to quantify radiolytic gas production for all salt samples except UF4. Production rates are reported as the salt G-values, measured as number of fluorine molecules produced per 100 eV of energy absorbed (molecules F2/100 eV). The G-values of the salts were found to be G(LiF) ~0.004, G(BeF2) ~0.009, G(ThF4) ~0.021, and G(FLiBe-UF4) ~0.005.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.RST/Reactor Physics and Nuclear Material
The shadow of reality in Austerlitz: an investigation about the photography in W. G. Sebald
No full textNo ano de 2001, foi publicado o último livro do já então célebre escritor alemão W. G. Sebald, Austerlitz. Marcado pela digressão, pelo tom melancólico, pelo emprego de remissões factuais e pelo uso de fotografias, o livro se caracteriza como um gênero híbrido entre o factual e o fictional, que também pode ser denominado de autoficção. A presente dissertação se concentra na função da fotografia em Austerlitz, valendo-se justamente de sua relação com o texto, com os limites da representação e com a memória. Embora trate-se de uma narrativa assumidamente ficcional, procurase na presente investigação averiguar como o caráter indicial da imagem fotográfica é manipulado pelo autor e como a manipulação da fotografia enquanto documento indicativo de evidência e testemunho atua na composição de uma narrativa que pode servir como uma saída para o impasse da representação na literatura e na memória pós-Auschwitz. Para tanto, a análise a seguir, embora em alguns momentos procure apresentar em sua própria estrutura o caráter digressivo da narrativa sebaldiana, foca sua atenção na tematização e na reprodução da fotografia no texto, assim como nos procedimentos poéticos revelados pelo espólio do autor, preservado em Marbach am Neckar, Alemanha.In 2001 was published the last book of the renowned German author W.G. Sebald, Austerlitz. The digression, the melancholic tone, the use of factual references and photographs in the text are characteristic for the narrative, which is also marked by its hybrid genre between the factual and the fictional, that can also be called autofiction. The objective of this dissertation is to analyze the function of photographs in Austerlitz, especially in conjunction with the text, with the limitation of their illustrations and with memory. Even if Austerlitz actually is called a fictional narrative, the present investigation seeks to ascertain how the indicative nature of photographic images can be manipulated by the author and how the manipulation of the photograph as evidence and witness account acts in the composition of a narrative, which can be a solution to the representation\'s problem in the literature and in the memory after Auschwitz. The analysis, which in part attempts to introduce the digressive character of the sebaldian narrative, focuses on the topicalization and reproduction of photography inside the text, and on the poetic technique which may be revealed by the author´s heritage stored in Marbach am Neckar, Germany
