1	Rural road quality, farm efficiency and income in Ethiopia. Development working papers series 3. Working paper No. 01/15 Wondemu, Kifle Asfaw 06 1900 (has links) yes / Small scale farmers in Ethiopia are already operating on their land frontier and the scope for an increase in production and rural income should come, among others, through improvement in technical and allocative efficiency. Although the stake of efficiency improvement is substantial, a number of empirical studies undertaken to identify the determinants of efficiency however are few. Moreover, although road infrastructure is among key public goods that significantly influences the farm level economic efficiency, empirical studies that have considered its role in farm efficiency analysis is scarce. This research investigated the link between the quality of rural road and farm level allocative and technical efficiency as well as the impact of inefficiency on farm income. The result showed that households that have all weather road access are 16% technically and two times allocatively more efficient. Both allocative and technical inefficiencies reduce income; the adverse impact of technical inefficiency on income however is stronger. Although household specific factors have contributed to the observed inefficiencyin most cases it is exogenously driven, namely, it is a rational response to market imperfection and risks. Interventions that reduce market and production risks will increase crop output and farm income.

3	ESTIMATING THE ECONOMIC LOSSES FROM DISEASES AND EXTENDED DAYS OPEN WITH A FARM-LEVEL STOCHASTIC MODEL Liang, Di 01 January 2013 (has links) This thesis improved a farm-level stochastic model with Monte Carlo simulation to estimate the impact of health performance and market conditions on dairy farm economics. The main objective of this model was to estimate the costs of seven common clinical dairy diseases (mastitis, lameness, metritis, retained placenta, left displaced abomasum, ketosis, and milk fever) in the U.S. An online survey was conducted to estimate veterinary fees, treatment costs, and producer labor data. The total disease costs were higher in multiparous cows than in primiparous cows. Left displaced abomasum had the greatest costs in all parities ($404.74 in primiparous cows and $555.79 in multiparous cows). Milk loss, treatment costs, and culling costs were the largest three cost categories for all diseases. A secondary objective of this model was to evaluate the dairy cow’s value, the optimal culling decision, and the cost of days open with flexible model inputs. Dairy cow value under 2013 market conditions was lower than previous studies due to the high slaughter and feed price and low replacement price. The first optimal replacement moment appeared in the middle of the first parity. Furthermore, the cost of days open was considerably influenced by the market conditions. disease economics cost of days open stochastic farm-level sensitivity analysis Dairy Science
4	Farm level economics of winter wheat production in the Canadian Prairies Yang, Danyi 11 1900 (has links) This research project estimated economic costs and benefits of winter wheat production in the Canadian Prairies at a farm level. A combination of Net Present Value analysis and Monte Carlo simulation was used to build cash flow farm models by province and soil zone. The objective of this study was to examine the economic feasibility of winter wheat production on the Prairies. Results show that Prairie farmers will benefit from growing winter wheat if crop research further improves cold tolerance, yield, or quality of winter wheat. Incorporating winter wheat into crop rotations has potential to increase farmers’ wealth in the Canadian Prairies. / Agricultural and Resource Economics winter wheat farm level analysis Monte Carlo simulation Net Present Value

6	Quantitative Agricultural Policy Impact Analysis at Enhanced Farm & Regional Resolution Gocht, Alexander 18 June 2024 (has links) In dieser Habilitationsschrift werden elf ausgewählte Zeitschriftenartikel vorgestellt. Alle Artikel zielen darauf ab, die Heterogenität der Betriebe des Agrarsektors durch eine bessere Auflösung der Angebotsmodelle zu berücksichtigen. Der erste Abschnitt konzentriert sich auf die Anwendungen mit dem partiellen Gleichgewichtsmodell CAPRI. Der Abschnitt deckt ein breites Spektrum politischer Fragen ab, zum Beispiel, Kopplung bzw. Konvergenz der Direktzahlungen, Ökologisierung, Verringerung der Treibhausgasemissionen und Kohlenstoffsequestrierung. Ich zeige, dass betriebsbezogene Angebotsmodelle eine detailliertere Analyse politischer Auswirkungen ermöglichen. Zudem erlauben diese Angebotsmodelle eine Verknüpfung mit Modellen höherer räumlicher Auflösung. Der zweite Abschnitt befasst sich mit methodischen Fragen zur Schätzung struktureller Veränderungen auf der Ebene der Betriebstypen in einem EU-weiten Ansatz. Der entwickelte Ansatz hilft, Faktoren, die den landwirtschaftlichen Strukturwandel beeinflussen, besser zu bestimmen und bietet die Möglichkeit einer umfassenden Analyse des landwirtschaftlichen Strukturwandels in der EU. Es wird gezeigt, dass die Ergebnisse zum Strukturwandel auch in der Modellierung berücksichtigt werden können. Dafür wurden Methoden entwickelt, die die Wahrung der Konsistenz der regionalen Ebene und die Berücksichtigung von betriebstypspezifischen Bilanzen, Indikatoren und Veränderungen in der Zahl der landwirtschaftlichen Betriebe gewähren. Der letzte Abschnitt befasst sich mit Methoden zur Rückschätzung von zensierten Daten. Ich untersuche verschiedene Datenaggregationsansätze, wie zum Beispiel, ein lokales gewichtetes Durchschnittsverfahren und ein bayesianisches Schätzverfahren, um Parameter für die zensierten Daten zu ermitteln, die der Realität so weit wie möglich entsprechen. / In this habilitation thesis, eleven selected journal articles were presented. All articles aimed to improve the resolution and thus reduce aggregation error to better account for farm heterogeneity in the agricultural sector models. The first section focused on model application with the partial equilibrium model CAPRI at the farm-type level. It covered many policy issues, such as coupling, convergence, greening, GHG mitigation, and carbon sequestration. I demonstrate that the farm-type supply models enable a detailed analysis of various policy impacts. It was demonstrated that the EU's supply models could improve model linkage with higher spatial resolution models, thus further closing the gap with spatial land-use models. The second section addressed significant methodological queries about estimating structural changes at the farm-type level in an EU-wide approach. A regional approach helps to identify better factors affecting agricultural structural change. The approach offers the opportunity for a comprehensive and previously unachievable analysis of agricultural structural change in the EU. Integrating the development into the CAPRI farm-type model poses challenges with the top-down approach. It requires maintaining consistency with the regional NUTS2 level and considering farm-type-specific balances, indicators, and changes in the number of farms from the structural change estimation. The last section addressed methods for back-estimating censored data. I explored different data aggregation approaches, such as a local weighted average method and a Bayesian estimation procedure, to establish parameters for the censored data that match reality as closely as possible.
