Can the small dairy farm remain competitive in US agriculture? 总被引:1,自引:0,他引:1
Smaller dairy farms in the US are observed to have higher costs than larger farms, and whether those higher costs are due to technology or inefficiency has implications for policy to address the small farm. If high cost of production on smaller farms is due to a higher cost frontier, then to make small farms competitive would require research to devise and design technology that is suitable for small farms. If instead high cost is due to inefficiency, then educational approaches are needed to ensure small dairy farms use technology efficiently. To determine the cause of higher costs on small farms, the cost of milk production by farm size was decomposed into frontier and efficiency components with a stochastic cost curve using data on USA dairy farms. Although the frontier cost of production decreases with farm size, that cost reduction is not as pronounced as a cost curve that includes inefficiency. The higher cost of production on many smaller farms is caused by inefficiency rather than technology. 相似文献

Zusammenfassung Eine ?konometrische Studie über die Beziehung zwischen Arbeitslosigkeit und offenen Stellen im Vereinigten K?nigreich. — Dieser
Aufsatz soll zeigen, da\ die stabile Beziehung zwischen echter Arbeitslosigkeit und echten offenen Stellen seit 1966 unterbrochen
ist. Au\erdem sollen die Faktoren untersucht werden, die die Beziehung zwischen echter Arbeitslosigkeit und echten offenen
Stellen bestimmen, wobei einerseits ein ?konometrisches Modell, das auf nichtbeobachtbare Variable besonders eingeht, und
andererseits eine neoklassische Theorie der überschu\nachfrage herangezogen wird. Die allgemeine Hypothese in diesem Artikel
lautet, da\ sowohl die echte als auch die registrierte oder gemessene H?he der Arbeitslosigkeit infolge verschiedener Gesetze
und/oder des Rückgangs der wirtschaftlichen Aktivit?t angestiegen ist. Anschlie\end werden zwei weitere Modelle konstruiert,
um die Rolle der Nachfrage- und Angebotsfaktoren zu analysieren.
Résumé Une étude économétrique sur la relation entre le ch?mage et les vacances en Royaume-Uni. — Le but de cet article est de démontrer que la relation stable entre le vrai ch?mage et les vrais vacances a croulé depuis 1966 et d’analyser les facteurs qui déterminent les relations entre le vrai ch?mage et les vrais vacances en appliquant séparément des modèles économétriques avec des variables inobservables et une théorie néoclassique de la demande d’excès. Notre hypothèse générale est que le montant du vrai ch?mage et le montant du ch?mage régistré ou mesuré augmentaient comme conséquence de la législation gouvernementale et/ou de la baisse de l’activité économique. Finalement, l’auteur construit deux modèles de plus pour analyser le r?le des facteurs de demande et d’offre.
Resumen Un estudio econométrico sobre la relación entre empleo y vacantes en el Reino Unido. — Los objetivos de este artículo son mostrar que la relación estable entre desempleo verdadero y vacantes verdaderas se ha quebrado a partir de 1966 y también analizar los factores subyacentes a las relaciones de desempleo verdadero y vacantes verdaderas separadamente, usando modelos econométricos con variables no observables y una teoría neoclásica de exceso de demanda. Nuestra hipótesis general es que tanto la cantidad verdadera de desempleo y el desempleo registrado o medido creció como consecuencia de la legislación gubernamental y/o la declinación en la actividad económica. Finalmente, formulamos dos modelos adicionales para analizar el rol de factores de demanda y oferta.相似文献

Farm households diversify their income sources by working off the farm. This is a risk management strategy that is used by farm households in both developed and developing countries. Income diversification via off-farm work is associated with higher incomes and food consumption. However, little is known about the association between off-farm work and farm household food expenditures. In an effort to bridge this gap, this study attempts to assess the impact of off-farm work decisions by the operator and/or the spouse on the food expenditures of the farm household. Using a nationwide farm household survey in the United States and new econometric method, we find that the decisions of the operator and/or the spouse to work off the farm are significantly interrelated (29%). However, these two decisions affect food expenditures in different ways. The operator’s off-farm work decision is positively related to food expenditures, while the spouse’s decision is negatively associated with expenditures on food by the farm household. 相似文献

In Germany, a lively debate about the reform of the financial equalisation scheme between the member states (“Länder”) is under way. There is broad consensus that the member states’ financial responsibility has to be strengthened. A reduction of the transfer level of tax receipts from high-income to low-income states could achieve this objective, but at the cost of solidarity between states. To avoid this trade-off, the authors propose an indicator-based risk adjustment scheme. Their aim is to equalise different financial needs, not only differences in tax revenues across states. Risk adjustment schemes are a well-established instrument, especially in social health care systems. 相似文献

This study examines the effects of off‐farm income on food expenditures of rural Bangladeshi households. Our analysis yields unbiased estimates of the unconditional impact of off‐farm income on food expenditures and reveals the heterogeneous effects that occur across the distribution of total food consumption expenditures. The findings suggest that the impacts of off‐farm income are uniformly positive across the unconditional quantile regression and significantly increase food consumption expenditures for all quantiles, except for the 25th quantile. In addition, we found that schooling, experience, and location of the household increase the food expenditures of rural households. Most importantly, this article argues that female‐headed rural households in which the female works off the farm tend to have significantly lower food expenditures. 相似文献
