1. Using a Farmer?s Beta for Improved Estimation of Actual
Production History (APH) Yields
Carriquiry, Miguel A.
Babcock, Bruce A.
Hart, Chad E.
The effect of sampling error in estimation of farmers? mean
yields for crop insurance purposes is explored using farm-level
corn yield data in Iowa from 1990 to 2000 and Monte Carlo
simulations. We find that sampling error combined with
nonlinearities in the insurance indemnity function will result in
empirically estimated crop insurance rates that exceed
actuarially fair values by between 2 and 16 percent, depending on
the coverage level and the number of observations used to
estimate mean yields. Accounting for the adverse selection caused
by sampling error results in crop insurance rates that will
exceed fair values by between 42 and 127 percent. We propose a
new estimator for mean yields based on a common decomposition of
farm yields into systemic and idiosyncratic components. The
proposed estimator reduces sampling variance by approximately 45
percent relative to the current estimator.

2. The Marketing Structure in Agribusiness during the Transition
in Bulgaria
Steve Murray

Bulgaria is moving toward a food processing and marketing system
which resembles that of Western Europe and the U.S. Large grocery
chains from Germany, Austrai and Turkey are building supermarkets
and hypermarkets in Bulgaria?s larger cities. However, income
in Bulgaria remains much lower than in Western Europe and most
Bulgarian consumers cannot afford to shop in the new stores yet.
Neighborhood markets, which serve average Bulgarians, are
expanding their product selections and remain the primary
shopping venue. Food processing plants in Bulgaria are being
upgraded to meet EU standards. Farmers are getting more efficient
as land is consolidated. On the whole, the agriculture and
agribusiness sectors in Bulgaria are improving.
