Ökonomen wie Wirtschaftspolitiker berufen sich auf die Neutralitätstheorie des Geldes, wenn sie eine Entpolitisierung der Geldpolitik fordern. Sowohl die Theorie der Geldneutralität als auch das Paradigma der Entpolitisierung der Geldpolitik sind jedoch problematisch. Die politökonomischen Entwicklungen nach der globalen Finanz- und Wirtschaftskrise 2007/2008 und die jüngsten Kontroversen über die Rolle und Bedeutung von Geld haben dies deutlich vor Augen geführt. Die vorliegende Arbeit diskutiert zunächst die konzeptionellen Grundlagen und theoretischen Modelle der Geldneutralität. Anschließend werden die zentralen theoretischen Annahmen und Aussagen der Neutralitätstheorie aus einer kritischen heterodoxen Perspektive hinterfragt. Es wird argumentiert, dass Geld eine nicht-neutrale Produktionskraft ist, die weder ökonomisch noch sozial neutral ist. Die Bedingungen, unter denen Geld verfügbar ist und zirkuliert, sind richtungsweisend für die ökonomische Entwicklung. Daher kann es auch kein neutrales Geld oder gar eine apolitische Geldpolitik geben.
The economic impact analysis contained in this book shows how irrigation farming is particularly susceptible when applying certain water management policies in the Australian Murray-Darling Basin, one of the world largest river basins and Australia’s most fertile region. By comparing different pricing and non-pricing water management policies with the help of the Water Integrated Market Model, it is found that the impact of water demand reducing policies is most severe on crops that need to be intensively irrigated and are at the same time less water productive. A combination of increasingly frequent and severe droughts and the application of policies that decrease agricultural water demand, in the same region, will create a situation in which the highly water dependent crops rice and cotton cannot be cultivated at all.
Diese Arbeit beschäftigt sich mit dem Thema Beteiligungsmanagement und der damit verbundenen Steuerung öffentlicher Unternehmen auf kommunaler Ebene. Der Ausgangspunkt der Untersuchung ist die Erkenntnis, dass eine Kommune keine absolute Kontrolle über ihre öffentlichen Unternehmen ausüben kann und sollte. Stattdessen wird angenommen, dass im Zuge einer effizienten Steuerung eine Fokussierung auf relevante Themen, Bereiche und Aktivitäten der öffentlichen Unternehmen erfolgt. Da die Steuerung öffentlicher Unternehmen aufgrund der Vielzahl involvierter Akteure nur schwierig zu untersuchen ist, steht in der vorliegenden Analyse die speziell für das kommunale Beteiligungsmanagement eingerichtete „Organisationseinheit Beteiligungsmanagement“ im Mittelpunkt. Die Forschungsfrage lautet: Welche Faktoren erklären den Steuerungsfokus einer „Organisationseinheit Beteiligungsmanagement“? Im Zuge einer explorativen Annäherung an die Forschungsfrage werden vier Perspektiven aus der Literatur verschiedener Forschungsgebiete, im Besonderen aber der Agencification-Literatur, hergeleitet: eine strukturelle, eine aufgabenspezifische, eine kulturell-vergangenheitsbezogene sowie eine umweltbezogene Perspektive. Mit Hilfe dieser Perspektiven werden sowohl verwaltungs- als auch unternehmenszentrierte Faktoren erarbeitet, deren Einfluss auf die Wahl des Steuerungsfokus untersucht wird. Das Ergebnis der explorativ-vergleichenden Fallstudie von insgesamt neun kommunalen Organisationseinheiten Beteiligungsmanagement zeigt, dass die untersuchten Faktoren entweder eine Intensivierung bzw. veränderte Verortung oder eine Diversifizierung des Steuerungsfokus erklären. Eine Diversifizierung bedeutet, dass eine Vielzahl verschiedener Fokusse berücksichtigt wird.
Diese Arbeit beschäftigt sich mit der Motivation von Mitarbeitern an öffentlichen wissenschaftlichen Einrichtungen. Anhand einer Mitarbeiterumfrage am Leibniz-Institut für Agrartechnik Potsdam-Bornim e. V. werden mehrere Hypothesen untersucht, die auf der Self-Determination-Theory basieren. Die Analyse zeigt, dass viele Befragte eine hohe autonome Motivation aufweisen. Insbesondere das Gefühl, Wahlmöglichkeiten und Gestaltungsspielräume bei der Arbeit zu besitzen, beeinflusst die Motivation positiv. Während Führungskräfte dieses Gefühl der Autonomie stärken können, haben Charaktereigenschaften keinen Einfluss hierauf. Darüber hinaus zeigt sich, dass in der Wissenschaft ein Gefühl der sozialen Eingebundenheit im Arbeitskontext keine bedeutende Rolle zu spielen scheint.
Bolivia is one of the poorest countries in Latin America. This study analyzes whether rural poverty increases the incidence of food insecurity and whether food insecurity perpetuates the condition of poverty among the rural poor in Bolivia. In order to achieve this aim, the risks that households face and the capacity of households to implement coping strategies in order to mitigate vulnerability shocks are identified. We suggest that efforts by households to become food secure may be difficult in rural areas because of poverty and the vulnerability associated with a lack of physical assets, low levels of human capital, poor infrastructure, and poor health; as well as the precarious regional environment aggravating the severity of vulnerability to food insecurity.
In Chapter 1 of the dissertation, the role of social networks is analyzed as an important determinant in the search behavior of the unemployed. Based on the hypothesis that the unemployed generate information on vacancies through their social network, search theory predicts that individuals with large social networks should experience an increased productivity of informal search, and reduce their search in formal channels. Due to the higher productivity of search, unemployed with a larger network are also expected to have a higher reservation wage than unemployed with a small network. The model-theoretic predictions are tested and confirmed empirically. It is found that the search behavior of unemployed is significantly affected by the presence of social contacts, with larger networks implying a stronger substitution away from formal search channels towards informal channels. The substitution is particularly pronounced for passive formal search methods, i.e., search methods that generate rather non-specific types of job offer information at low relative cost. We also find small but significant positive effects of an increase of the network size on the reservation wage. These results have important implications on the analysis of the job search monitoring or counseling measures that are usually targeted at formal search only. Chapter 2 of the dissertation addresses the labor market effects of vacancy information during the early stages of unemployment. The outcomes considered are the speed of exit from unemployment, the effects on the quality of employment and the short-and medium-term effects on active labor market program (ALMP) participation. It is found that vacancy information significantly increases the speed of entry into employment; at the same time the probability to participate in ALMP is significantly reduced. Whereas the long-term reduction in the ALMP arises in consequence of the earlier exit from unemployment, we also observe a short-run decrease for some labor market groups which suggest that caseworker use high and low intensity activation measures interchangeably which is clearly questionable from an efficiency point of view. For unemployed who find a job through vacancy information we observe a small negative effect on the weekly number of hours worked. In Chapter 3, the long-term effects of participation in ALMP are assessed for unemployed youth under 25 years of age. Complementary to the analysis in Chapter 2, the effects of participation in time- and cost-intensive measures of active labor market policies are examined. In particular we study the effects of job creation schemes, wage subsidies, short-and long-term training measures and measures to promote the participation in vocational training. The outcome variables of interest are the probability to be in regular employment, and participation in further education during the 60 months following program entry. The analysis shows that all programs, except job creation schemes have positive and long-term effects on the employment probability of youth. In the short-run only short-term training measures generate positive effects, as long-term training programs and wage subsidies exhibit significant locking-in'' effects. Measures to promote vocational training are found to increase the probability of attending education and training significantly, whereas all other programs have either no or a negative effect on training participation. Effect heterogeneity with respect to the pre-treatment level education shows that young people with higher pre-treatment educational levels benefit more from participation most programs. However, for longer-term wage subsidies we also find strong positive effects for young people with low initial education levels. The relative benefit of training measures is higher in West than in East Germany. In the evaluation studies of Chapters 2 and 3 semi-parametric balancing methods of Propensity Score Matching (PSM) and Inverse Probability Weighting (IPW) are used to eliminate the effects of counfounding factors that influence both the treatment participation as well as the outcome variable of interest, and to establish a causal relation between program participation and outcome differences. While PSM and IPW are intuitive and methodologically attractive as they do not require parametric assumptions, the practical implementation may become quite challenging due to their sensitivity to various data features. Given the importance of these methods in the evaluation literature, and the vast number of recent methodological contributions in this field, Chapter 4 aims to reduce the knowledge gap between the methodological and applied literature by summarizing new findings of the empirical and statistical literature and practical guidelines for future applied research. In contrast to previous publications this study does not only focus on the estimation of causal effects, but stresses that the balancing challenge can and should be discussed independent of question of causal identification of treatment effects on most empirical applications. Following a brief outline of the practical implementation steps required for PSM and IPW, these steps are presented in detail chronologically, outlining practical advice for each step. Subsequently, the topics of effect estimation, inference, sensitivity analysis and the combination with parametric estimation methods are discussed. Finally, new extensions of the methodology and avenues for future research are presented.
Critics argue that there has been a trend among Microfinance Institutions (MFI) to focus on profitability in order to stay financially sustainable. This made some institutions neglect the social mission of microfinancing. In this paper I intend to examine if empirical evidence supports this so called mission drift hypothesis as well as other claims in this context. Using the global panel data set of the MIX (Microfinance Information Exchange), which gathers from 1995 to 2010 and contains up to 1400 institutions with a high variety of organizational forms, I was able to identify a world-wide mission drift effect in their social goal of reaching out the poorest part of the population. Furthermore, I find that, on average, the outreach of an MFI has a significant negative influence on its short and long term financial performance. Despite that, I eventually proved that the probability that an MFI worsens its social performance substantially increases if its profitability has decreased in the previous years.
