Estimates of the marginal internal rate of return to expenditures for research by the Maine Agricultural Experiment Station are presented. Estimates are performed using ridge regression under an array of specifications, including alternative functional forms, lag structures, costs of public funds, and variable specifications. The results are consistent with many previous results that imply an underinvestment in agricultural research.
Appreciation is expressed to Wallace Huffman, Michele Marra, James McConnen, and Alan Kezis. Anonymous reviewers provided a number of useful suggestions. MAES Publication 1522.
