Estimating Input Use and Production Costs From Farm Survey Panel Data

Econometric estimation of enterprise input use and production costs offers a less expensive alternative to special surveys. Estimates of input allocation are of use within programming models, for policy analysis and income forecasting. However, simple ordinary least squares estimation has been plagued by a number of problems and the results have been disappointing. This paper provides some empirical evidence on the extent to which these problems can be overcome, or at least mitigated, through exploitation of panel data sets and appropriate panel data estimation techniques. The results confirm that this approach provides some improvement in estimation results, but some practical and methodological problems remain.     

Agricultural policy reform in the United States: an unfinished agenda

The 1996 Federal Agriculture Improvement and Reform Act (FAIR) contained important breaks with a tradition of crop–by–crop subsidies dating back to the Agricultural Adjustment Act of 1933. Farmers with recorded base acres were given the opportunity (which nearly all accepted) to sign a seven–year 'contract' with the US Department of Agriculture (USDA), under which payments will be continued on the merged base acres on a declining schedule until the year 2002. FAIR is an unfinished agenda. First, the coverage of 'freedom to farm' is only partial, with numerous commodities left out of the decoupling programme. Second, the largest producers will augment their already significant receipts with generous lump sum transfers from USDA. This will further reinforce the concentration of roughly 90 per cent of receipts and payments in the hands of the 100 000 to 200 000 largest producers of field crops. An alternative would be to make payments in times of low marketing receipts which recede when prices are high.     

Competitive Grants and the Funding of Agricultural Research in the United States

Efforts to improve public agricultural research efficiency include calls to increase use of competitive grants. This paper empirically assesses different instruments the USDA uses to fund state-level research. Compared with other instruments, competitive grants focus more on basic research and are concentrated among fewer states. Model results suggest that top-ranked biology and agricultural science programs were strong determinants of states' shares of competitive grants. Other significant factors were agricultural sector size and number of agricultural scientists. USDA-funded state-level research focus did not change significantly because competitive grants comprised only 15% of these funds and other instruments counteracted their influence.     

Agricultural competitiveness: The case of the United States and major EU countries

Growth in the agricultural GDP of four major European countries is compared with US agricultural growth for the period 1974–1993. The agricultural sector's relative prices are taken into account along with economy-wide factor market adjustments. For Denmark, France, Germany and the UK, the effects of declining real prices and changes in input levels on growth in agricultural GDP are relatively small. Total Factor Productivity (TFP) growth appears to be the major contributor to European agricultural GDP growth. In comparison, TFP is the major source of growth in US agricultural GDP, but its rate of growth is lower than the European countries. In contrast, the declining real prices for US agriculture had a relatively large effect on its GDP. However, in recent years, the effects of declining real prices and declining rates of growth in TFP on European agriculture are relatively large. In the longer-run, the relative competitiveness of US agriculture is largely dependent on its ability to sustain and increase growth in TFP.     

A Growth Accounting Analysis of Cost Efficiency in Milk Production for Six Northern States in the United States

This paper reports on the use of a growth accounting approach to calculate and decompose cost efficiency indices into technical change, regional competitive advantage stemming from spatial effects, and economies of size. Dairy farm data for Connecticut, Maine, Vermont, Michigan, New York and Pennsylvania for the years 1968, 1970, 1977, 1980 and 1988 are utilized in the analysis. The results show that technological change yielded a 1.8% average annual rate of cost reduction over the period studied. In addition, medium and large farms were, on average, 12% to 20% more efficient than small farms. Pennsylvania had a distinct competitive advantage (13.8%), while Maine exhibited a clear competitive disadvantage (−18.2%) in producing milk relative to New York.

Migration to the United States and Mexican rural development: a case study

An analysis of the impact of migration to the United States on the sending community and on the labor market in the receiving country is presented based on a case study of Las Animas, Mexico. "As the community becomes increasingly involved in migration, tendencies can be identified regarding changing migration patterns, class differentiation among villagers, impact of migration on village economy, and the changing role of Mexican workers in California labor markets. Results indicate the importance of social networks in determining the outcome of migration; while migration is individually rational, it is a factor of stagnation for village economy, and it helps reproduce segmented California labor markets."     

Food Label Regulations in the United States and European Community:

Growing interdependence among the world's food markets presents increased trade and investment opportunities for food firms. Although international trade agreements have recently been negotiated which will likely lead to increased food trade, especially among Western nations, revised product standards and technical regulations used in the course of implementing these agreements have potential to create trade barriers that are less obvious. This paper assesses recent developments in food quality and labeling regulations in the European Community (EC) and United States. The regulatory changes taking place in these large trading partners have the potential to result in trade barriers based on meeting technical standards, especially since the reforms are being pursued independently in each country.
