There are a number of estimation methods available to the econometrician. They range in complexity from least squares, which takes only a few minutes with pencil and paper for a simple problem, to full information maximum likelihood, which requires a large-capacity electronic computer for...

It 15 difficult to obtain c1osed-fonn solutions for input demand equations that are conducive to econometric estimation and policy analysis when the production function IS unknown Developments In the theory of duality facilitate obtaining such equations This article provides three examples of...

The widespread growth of bank (and other) charge-account plans implies a distinct possibility that retail food marketing, as well as the food producing, processing, and distributive sectors, indirectly, may become involved to a significant degree in a consumer credit operation. The purpose of...

It might be expceted that a more active conversation betwecil cnumerator and respondent would provide better data in an interview. Such an effect had been report!:d for health interviewing. However, it was not discovered in farm intervicwing in the survey analyzed in this paper. There is...

The role of the agricultural sector in economic growth has recently come under study. Numerous articles have appeared on the theoretical aspects (capital formation, increased productivity, etc.) of agriculture's contribution as well as on the numerical magnitude of changes that have taken place....

The authors examine the small sample properties and forecasting performance of estimators In models using the Box-Cox transformation via a Monte Carlo experiment They develop a simple,estimator for the expected value of the untransformed dependent variable They show that the sign and magnitude...

A particular numerical analytical technique for solving systems of simultaneous equations which offers several advantages to the user over other numerical techniques is discussed. The Gauss-Seidel algorithm is simply an iterative technique which requires no derivatives, matrix inversion,...

ERS provides economic information on the near-term agricultural outlook and on longrun projections. Here is an overview of efforts to improve such information through comprehensive quantitative models. The various models incorporate intercommodity relationships within agriculture, aggregate farm...
