| The financial implications of manipulating nitrogen (N) inputs and management strategies for beef production systems were assessed. One-hectare grassland farmlets were grazed to a target sward height by beef steers; herbage surplus to grazing requirements was cut for silage. Three systems were compared: ‘CN’, conventional mineral N application to a grass monoculture and broadcast slurry; ‘TN’, tactical mineral N application at fortnightly intervals to a grass monoculture with slurry injection and the early housing of cattle; ‘GC’, a mixed grass/white clover sward with no mineral N addition and slurry injection. Comparisons were made on two contrasting soil types: a freely-draining sandy loam (site 1) and a poorly drained clay (site 2). Financial budgets... |

| Both Indonesia and Vietnam, as members of ASEAN, have negotiated a free trade agreement with China (ACFTA). ASEAN Member States can independently negotiate their tariff reductions. Both countries are generally aware of the opportunities access to the large Chinese market may present, but both are concerned to differing degrees about being flooded with Chinese imports, including agricultural products. As the time for implementation approaches, Indonesia has expressed a desire to renegotiate its tariff reduction schedules to protect sensitive sectors, including agriculture. By contrast, Vietnam, just over the border from China and with a history of informal trade, seems more accepting of the prospects. A global general equilibrium model, GTAP, is used to... |

| Recent trends in livestock concentration suggest that there may be an increasing risk of water pollution from manure applications. These trends in livestock operations may be offsetting improvements in commercial fertilizer management that have the potential to reduce the risk of water pollution. This conclusion was derived by tracking excess nutrient trends between 1996 and 2002 and by examining measures of economic performance for livestock farms. First, a link was established between the expansion of AFOs (Animal Feeding Operations) and excess nutrients from commercial fertilizer and manure sources. Second, technical efficiency was measured in order to identify whether technical efficiency explains structural change and in order to see whether... |

| Since the first half of the 20th century, the input-output (IO) table has been the backbone of much empirical work used to support policy analysis and develop economy-wide models. The need for accurate, up-to-date IO tables is thus essential for establishing the validity of the empirical work that follows from them. However, the construction of an IO table for any given country is an expensive and time-consuming endeavor. Current and accurate IO tables for many countries are thus often difficult to obtain on a regular basis. Once an initial IO table has been constructed, a common workaround is to collect partial information for subsequent periods, such as final demands for commodities within the economy, and then employ a Bayesian parameter estimation... |

| Two efficient farms are constructed for the brown soils of Saskatchewan, Canada and for Mecklenburg, Germany based on producer panels. Both farms feature highly integrated cropping systems which take advantage of cropping synergies. However, farm risk is inherently different between the two because differences in 1) climate that gives rise to very different yield risk and cost structure, and 2) EU programs which offer fixed cash payments and stable sugar beet prices. As expected, risk is much higher for the Saskatchewan case farm - it has a chance of a negative cash flow of approximately one year in five. In sharp contrast, the Mecklenburg has very little chance of generating a negative cash flow. Hence, it is easy to understand why crop insurance and... |

| Agriculture and aquaculture have common features associated with their biological nature affecting risk exposure of the businesses. The aim of this paper is to compare risk exposure in salmon farming and agricultural enterprises in Norway by using an implicit error component model to examine the risk structure of yields, prices and economic returns at the farm level. Results indicate a higher farm-level year-to-year variability in yields, prices and economic returns in salmon farming than in agricultural enterprises. The variability in livestock enterprises was generally lower than for crop enterprises. Return on assets was highest in salmon farming with an average annual return of 9.2%. All of the agricultural farm types exhibited a negative average... |

| This study is the first to empirically assess the difference between the prevailing salary structures in economics and agricultural economics departments at public institutions in the United States. We find that average salaries in economics departments tend to be higher than salaries in agricultural economics departments. Regression analysis suggest that years since Ph.D. explains a greater proportion of salaries in agricultural economics departments while the tier of school explains a great proportion of salaries structure in economics departments. Regression results also suggest that the returns to publications in top 36 and other economics journals is higher in economics departments while publications in core and regional agricultural economics... |
