| Abstract: | "Ziel des Kooperationsprojekts 'Berufliche Weiterbildung als Bestandteil Lebenslangen Lernens' (WeLL) ist die Erstellung eines sogenannten Linked-Employer-Employee-Datensatzes, welcher Informationen zur beruflichen Weiterbildung von Arbeitgebern und Arbeitnehmern enthält. Für das Projekt wurden zunächst Betriebe zu ihrem Weiterbildungsverhalten interviewt. Anschließend wurden deren Beschäftigte zu diesem Thema befragt. Diese Arbeitnehmererhebung ist als Längsschnittbefragung mit drei Befragungszeitpunkten in 2007, 2008 und 2009 angelegt um Veränderungen der individuellen Weiterbildungsaktivitäten beobachten und zwischen kurzfristigen und mittelfristigen Weiterbildungseffekten unterscheiden zu können." Der Report enthält neben Informationen zur Datenbeschreibung, Datenerhebung, Datenaufbereitung, Anonymisierung und Datenzugang vorallem die Beschreibung der Variablen im Organisationsdatensatz, im Weiterbildungsdatensatz, im Querschnittsdatensatz und im Biographiedatensatz.

| Abstract: | "The Institute for Employment Research regularly informs about the current situation and future development on the labour market. For example, it serves as consultant of the Federal Employment Agency and its autonomous administrative bodies, and the Federal Ministry of Labour. Such information is necessary, for instance, in the course of budget planning and the monthly press releases of the Federal Employment Agency. The IAB's short reports on labour market forecasts usually find a large echo in the media. They are the basis for decision makers in politics, companies and associations as well as for other researchers. IAB's disaggregation of the forecast is unique. It provides information on unemployment by social codes II and III, employees in the regular or subsidized labour market, employment by status. All data is given for eastern and western Germany separately. This research report documents the procedure of IAB's forecasting in the short-run. The framework is the so called balance-sheet of the labour market which depicts the coherence of labour supply, (filled) labour demand, and unemployment. Forecast values in the balance-sheet are found by means of econometric forecasting, trend forecasting or plausible assumptions. The final forecast appears after a few iterations when all parts of the balance sheet are attuned to each other. Forecast evaluation reveals a similar accuracy as of other leading forecasting institutes." (author's abstract, IAB-Doku) ((en)) |

| Abstract: | In the past, many WTO member states have liberalized their trade policies unilaterally. However, they were decreasingly prepared to guarantee these measures multilaterally, that is to "bind" them. This paper analyzes the background of this development by resorting to three political economy arguments pro multilateral binding: the terms of trade externality argument, the "tying hand" argument, that is to protect a government which is prone to liberalize against domestic lobby groups, and finally the argument that trade policies are instruments for general political targets. For all three arguments, it is shown why an important driving force of mercantilistically motivated trade negotiations has become weaker, the reciprocity requirement. The paper recommends narrower negotiation issues and mandates to prevent a further rising heterogeneity of issues and negotiation partners |

| Abstract: | Through an implementation of the 2-level-approach due to Vesanto & Alhoniemi (2000), this paper addresses a number of problems typically seen when visualized interpretation of Self Organizing Maps (SOM) are applied to derive a systematic classification system in the hedge fund literature. Normally, a trained SOM does not result in an exact depiction of the detected structures of the input data, and is therefore challenging for visual interpretations. The 2-level-approach overcomes this problem and assures a consistent clustering of neighboring output units, and therefore an objective classification scheme. Through an empirical application, such an objective classification is derived. Building on this, further analyses concerning the misclassification and style creep problems are conducted. Within the ten-year sample period (31.01.1999 to 31.12.2008), which comprises 2789 hedge funds, organized in eleven strategies, six classes can be identified. This six-class taxonomy is fairly robust to different sub-sample periods, topologies and data-samples. According to the classification system applied here, it is shown that most of the analyzed hedge funds are inconsistent in their self-declared strategies. Furthermore, evidence of undisclosed trading style changes over time is identified – specifically, it is shown that misclassified hedge funds are more likely to change their trading style. |

| Abstract: | Because of increasing resource prices and thus, higher export profits, resource abundant countries become more and more constrained in implementing a sustainable resource management which realizes two main objectives: The development of competitive non-oil industries and the reduction of resource caused volatility. This paper surveys rationales, structures and effects of resource-based Souvereign Wealth Funds as an instrument of optimal resource management. The main objective is to find out if resource funds have some significant impact on macroeconomic stability and development. Therefore, chapter 2 gives a review of different "resource curse" theories to identify macroeconomic core indicators that should be affected by introducing SWFs. The next chapter introduces the theory of resource-based SWF by simulating a general optimal resource management under different scenarios in an infinite horizon model. It shows that resource funds can be an effective instrument to obtain stabilization as well as sustainability objectives. After discussing specific practical topics as different types of funds, the linkage to government budget and the portfolio management, chapter 4 starts with a descriptive analysis about the implementation of resource funds in three different countries: Norway, Russia and Azerbaijan. Other nations and regions were considered by short subsections. In chapter 5 an unbalanced panel data model with 30 countries from 1970-2006 is build to estimate the effects of resource-based SWF´s on resource curse, stabilization and sustainability by means of fixed and random effects estimator. Finally, a short criticism and outlook gives motivation for further research tasks. |
