Der Milchsektor ist einer der bedeutendsten landwirtschaftlichen Sektoren in der Europäischen Union. Seit die Reformen der Gemeinsamen Agrarpolitik 2005 in Kraft traten, wurde der Markt stark liberalisiert und ist durch zunehmende Preisschwankungen gekennzeichnet. Für die Michviehbetriebe ist dies eine Herausforderung, denn Faktorpreisunsicherheit ist eng mit den betrieblichen Entscheidungsprozessen für die optimale langfristige Nutzung der Produktionsfaktoren verbunden. Ein weitreichender Teil der Literatur analysiert den Zusammenhang zwischen Betriebsgröße oder Betriebsführung und ökonomischer Effizienz. Die statische Effizienzmessung ist weitverbreitet, vernachlässigt jedoch die zeitliche Abhängigkeit und die Anpassungsprozesse der quasi-fixen Faktoren. Dies wird im Konzept der dynamischen Effizienzmessung aufgegriffen. Das verwendete Effizienzmodell berücksichtigt zudem Faktorpreisunsicherheit. Der Beitrag dieser Dissertation ist es, die dynamische Effizienz westdeutscher Milchviehbetriebe erstmals unter Unsicherheit zu analysieren. Es wird untersucht, ob die Produktionsfaktoren technisch und allokativ effizient einsetzen werden. Zudem wird die Rolle der Unsicherheit für die Faktornachfrage und die Effizienzmessung beleuchtet. Die Ergebnisse zeigen, dass die Milchviehbetriebe auf einem hohen technischen Effizienzniveau arbeiten im Vergleich zur allokativen Effizienz und dass die Futternachfrage negativ mit der Futterpreisvolatilität verbunden ist. Investitionen reagieren negativ auf die Volatilität des Milchpreises, wobei der Einfluss der Unsicherheit mit zunehmender Betriebsgröße steigt. Die Ergebnisse belegen, dass die Preisunsicherheit bei der (dynamischen) Effizienzmessung von entscheidender Bedeutung ist und die Vernachlässigung zu niedrigeren Effizienzwerten führt und die Betriebe ineffizient erscheinen. Diese Ergebnisse sind nicht nur für Milchviehbetriebe relevant, sondern auch für Sektoren, die durch volatile Marktbedingungen gekennzeichnet sind. / Dairy farming, the most important farming sector in the European Union, has been subject to considerable de-regulation since the 2005 EU Common Agricultural Policy came into effect and to increased commodity price volatility. This is a new challenge for dairy farms, since price volatility is related to farm-level decision-making with regard to the optimal factor allocation in the long run. A vast body of literature relates economic efficiency to dairy farm characteristics such as size or managerial ability. However, it is common for static approaches of efficiency which ignore the role of time and the adjustment processes of farms with respect to the quasi-fixed factors to be applied. The intertemporal linkages of production and investment decisions are emphasized by dynamic efficiency and an extended model incorporates factor price volatility. The contribution of this thesis is to analyze the dynamic efficiency of German dairy farms under uncertainty, which thus far has not been done. The application aims to investigate whether West German dairy farms use their production factors in a technically and allocative efficient way in the long run. Moreover, the application will explore the role of uncertainty for factor demand and efficiency measurement. The results show that the farms operate at high levels of technical efficiency in comparison to allocative efficiency and that feed demand is negatively related to the variance of the feed concentrate price. Investment is negatively related to the variance of the milk price and the effect increases with farm size. The results further show empirical evidence for considering uncertainty when deriving (dynamic) efficiency measures: neglecting uncertainty within the estimation procedure will underestimate the average efficiency score, and thus farms appear inefficient. This finding is not only interesting for dairy farms; it also applies to other sectors that operate in highly-volatile markets.

Text in English / Cow size influences biological efficiency of individual animals, which influences herd composition and stock flow. This in turn influences the economic efficiency of the herd. This research followed the thread from animal size, to biological efficiency, to economic efficiency for beef cattle production under a typical production system in semi-arid South Africa. Cattle were grouped into three groups namely small, medium and large cattle, with mature weights of 300kg, 450kg and 600kg respectively. The net energy requirements of individual cattle were calculated for maintenance, growth, lactation and foetal production, for each of the three sizes. Growth rates, milk yield, reproduction rates, and management practices were assumed from existing research. Next the stock flow for a herd of small, medium and large cattle were calculated from the above. Income and expenses as commonly used in the research area were calculated from the stock flow. Gross profit above allocated costs were subsequently calculated for the three herds under the above-mentioned conditions. When assuming similar reproduction and growth rates for small, medium and large mature cattle, the following results were obtained: more heads of small cattle could be held on a set resource base, but the total live weight of a herd of large cattle that could be held on the same resource base was greater. This was mostly due to proportionately lower maintenance energy requirements in the herd of large cattle. In the simulation in this study, maintenance energy requirements for the herd of large cattle was 71.2%, compared to 72.0% for the herd of medium cattle and 73.1% for the herd of small cattle. Income from the herd of small cattle was the lowest, as less kilograms of beef were available to sell. Allocated costs for the herd of small cattle were the highest, due to a large number of expenses being charged per head of cattle. As a result, the herd of large cattle were more economically efficient than their smaller counterparts. Income above allocated costs for the herds of large, medium and small cattle were R1,182,865, R1,085,116 and R946,012 respectively. Larger cattle generally have a lower reproduction rate under similar conditions. No equation exists that directly links size to reproduction rates, especially considering the vast number of variables that influences reproduction rates. However, in the form of scenarios, it could be calculated that, given a reproduction rate of 80% for mature small cattle, when reproduction rates of large cattle were 24.7% lower than that of small cattle and the reproduction rates of medium cattle were 15.4% lower than that of small cattle, the large and medium herds became less profitable than the small herd. Smaller cattle mature faster than larger cattle which provides the opportunity for early breeding. When small cattle were bred early, at 15 months, at a calving rate of only 44.5% it was more profitable than when the same cows were bred at 24 months. When medium cattle were bred at 15 months, a calving rate of 37.0% was needed to be more profitable than when they were bred at 24 months. Even when the herd of small cattle were bred at 15 months with a reproduction rate of 100%, it could still not match the profitability of the herd of large cattle bred at 24 months given the reproduction rates of all other classes of animals were similar. When the herd of medium cattle were bred at 15 months, at a calving rate of 53.7%, it matched the profit of the herd of large cattle that were bred at 24 months, when the reproduction rates of other classes were equal. Scenarios were considered were feed intake was limited. When feed was limited to a specific amount, smaller cattle were more biologically efficient and cattle with potential for small mature sizes would grow to a larger size than cattle with potential for medium and large mature sizes. When feed was limited by a factor of the calculated energy requirements of small, medium and large cattle, large cattle were more effective. This is because large cattle use proportionately less energy for maintenance, which allows more energy to be allocated to growth, lactation and foetal production. When energy was limited to an amount per unit of metabolic weight, small cattle were more efficient than medium and larger cattle in the growth and production phases. Small, medium and large cattle were equally efficient (or inefficient) in the maintenance and lactation phases. Energy requirements of cattle in South Africa are commonly calculated using the Large Stock Unit (LSU). The LSU typically overestimates energy requirements for cattle, except in the lactation phase. When using the LSU to match small, medium or large cattle to a resource base, the LSU overestimates energy requirements of large cattle proportionately more than that of small and medium cattle. This is excluding the lactation phase, where energy requirements for all three sizes are underestimated and that of large cattle underestimated proportionately more. There are more considerations when matching cow size to managerial practices. A smaller body size is a natural adaptation to a semi-arid environment and this adaptation can be expressed in different ways. The number of animals on a resource base has implications on management practices. Having more heads of cattle on a resource base increases genetic variation of the herd, allowing for genetic progress to be made faster than in herd of fewer cattle. / Agriculture and  Animal Health / M.Sc.

本論文包含兩篇獨立但主旨相關的文章， 目的均在探討融資契約與廠商投資的關聯，以分析融資契約的實質效果。第一篇文章「股價資訊外部性與新投資之採行」研究權益證券(股票)集訊、揭訊功能的實質效益，我們由股價資訊公開所產生的外部效果，分析股價資訊效率性與廠商投資效率之間的關聯。在1.眾多異質廠商，2.投資具實質選擇權(real options)特性的假設下，內生化廠商與股市交易者的資訊取得決策，發現1. 均衡時廠商的投資與資訊取得決策取決於廠商技術水準與股價效率性之高低：高股價效率性時，無廠商取得新資訊，皆根據股價判斷投資，低股價效率性時，僅較低技術廠商根據股價資訊投資。2. 股價有額外的資訊揭露效果：由於廠商僅能獲得新資訊的部份效益，且廠商利用資訊有機會成本，將投資證券化可提高新資訊被揭露的可能性，使得資訊可被充份利用，提昇投資效率。3. 股價資訊可提增投資效率，增加廠商期望報酬，但當體系平均技術水準落後，新資訊的實質效益低落時，股價資訊公開的外部淨效益亦趨薄弱，故經濟發展初期，股市資訊公開的外部效益相對不重要。 第二篇文章「抵押品、財務槓桿與廠商投資」研究借貸契約中，抵押品舒緩借貸限制的作用，及其可能產生的實質效果。我們採用Williamson(1986,1987)的狀態確認成本模型(costly state verification model)，在該訊息不對稱模型，廠商向外融資面臨借貸限制，僅較高自有資金廠商可獲融資。當借貸市場資金相當寬鬆，資金供給恆大於資金需求，資金成本(無風險利率)為一由模型外因素所決定的外生參數時，抵押融資不影響資金成本，此時抵押品具有舒緩借貸限制的作用，體系財務槓桿提高，期望查帳成本下降，投資的期望淨產出增加。若資金相對緊俏，無風險利率須由借貸市場均衡所內生決定時，長期而言，財務槓桿僅受體系資金寬鬆程度的影響，短期間抵押融資雖能提高財務槓桿，但隨槓桿之提高，資金需求增加，無風險利率上揚，在新的均衡，較低自有資金廠商投資的期望報酬下降，借貸利率上漲，反而增加其應負債務，資產狀況惡化，此即本文所欲突顯之抵押融資的潛在成本。 第一章 緒論 3 第一節 研究動機 3 第二節 研究內容與架構 5 第二章 文獻回顧 7 第一節 融資契約的功能 7 第二節 金融結構與實質經濟活動 13 第三節 股價資訊與廠商投資 18 第四節 抵押品與廠商投資 22 第三章 股價資訊外部性與新投資之採行 27 第一節 前言 27 第二節 基本模型 29 第三節 期中股市均衡與股價效率性 35 第四節 股價資訊外部效益 41 第五節 小結 46 附 錄 47 第四章 抵押品、財務槓桿與廠商投資 53 第一節 前言 53 第二節 基本模型 55 第三節 抵押融資模型-資金寬鬆時的抵押品效果 62 第四節 抵押融資模型-資金緊俏時的抵押品效果 66 第五節 小結 70 第五章 結論 72 第一節 研究限制 72 第二節 未來研究方向 77 參考文獻 79 / This dissertation collects two separate but related papers, both study the channel through which financing contracts can affect firms' investment decisions and the corresponding real effects. The first paper " Informational Externality of Stock Prices and Firms' New Investment Decisions" analyzes what real benefits the information acquisition and signaling function of stocks can produce. From the viewpoint of informational externality, stock prices may disclose some valuable information beneficial to firms' investment decisions. Under the assumptions of " heterogeneous technology" and "new investment as a real option", this paper finds 1. Firms' investment and information acquisition decisions are determined both by their own technology level and stock prices efficiency. With high price efficiency, no firms acquire information directly, all make investment decisions based on stock prices. With low price efficiency, most firms acquire information directly, only few low-tech firms make decisions according to stock prices. 2. Stock prices have additional signaling effect. Firms can ony get half benefits of new information, besides they have opportunity costs in using information. As a result, stock prices can enhance the possibility of information disclosure, improving investment efficiency. 3. When the economy is underdeveloped and the real benefit of new information is small, the net benefit produced by informational externality will be tiny. The stock prices externality effect is thus comparatively unimportant at the beginning stage of economy. The second paper " Collateral, Financial Leverage and Firms' Investment"analyzes the constraints-smoothing function of collateral and its real effects. By adopting Williamson's costly state verification model(1986,1987), I find that with this specific asymmetric information structure, there are financing constraints in capital markets, only firms whose own capital inputs are higher above some level can get borrowed capital. The question is " Can offering collateral smooth this kind of financing constraints?" In markets with abundant capital where capital supply always exceeds demand, capital cost(riskless interest rate)will be an exdogenously-determined parameter which won't be affected by collateral financing. In this scenario, collateral can smooth financing constraints, increase financial leverage and improve the net expected return of investment. On the contrary, if capital is not so abnudant that the capital cost should be determined endogenously by capital market equilibrium, then in the long run this economy's financial leverage depends only on the relative abundance of capital. Though collateral financing can increase financial leverage in the short run, as capital demand increases, capital cost will also increase. This will offset the initial smoothing effect of collateral. After full adjustment of capital cost, at the new equilibrium the financial leverage remains unchanged. However, the expected return of firms with lower own capital inputs become smaller, and their borrowing rates become higher which mean they have heavier debt burden and less net worth at the new equilibrium.

Im Rahmen des Transferprojektes sollen baubetriebliche Rahmenbedingungen und Kennwerte, die zur Beurteilung der wirtschaftlichen Anwendung des Verfahrens geeignet sind, erarbeitet werden. Untersucht werden soll die Applikation von textilbewehrtem Beton im Bereich der Sanierung und Verstärkung von großflächigen Betonbauteilen. Generell können Bauaufgaben in sehr vielen Fällen durch verschiedene Bauverfahren realisiert werden, die sich regelmäßig hinsichtlich der Kosten, der benötigten Bauzeit aber auch hinsichtlich der gelieferten Qualität und des Einflusses auf die Umwelt unterscheiden. Aus baubetrieblicher Sicht wird traditionell über den kalkulatorischen Verfahrensvergleich jenes Verfahren ermittelt, mit dem die Realisierung am wirtschaftlichsten ausgeführt werden kann. Falls qualitative Kriterien beim Verfahrensvergleich mit berücksichtigt werden sollen, stehen verschiedene Methoden zur Auswahl. Der Begriff Nutzwertanalyse wird häufig als Synonym für diese nichtmonetären Bewertungsverfahren verwendet. In diesem Sinne ist auch der Titel des Beitrages zu verstehen. Die Grundlage bilden die baubetrieblichen Rahmenbedingungen, welche im Rahmen dieses Forschungsprojektes bestimmt werden. Hierzu zählen unter anderem die Entwicklung einer Trockenmischung des zu verwendenden Betons aus der bisher verwendeten Standardrezeptur der TU Dresden und geeigneter Maschinen für die Applikation des textilbewehrten Betons.
