19. Testing expected utility maximization under price and quantity risk with a heterogeneous panel

Author

Yucan Liu and Shumway, C. Richard

Subjects
Uncertainty -- Analysis, Agricultural productivity -- Economic aspects, Time-series analysis -- Usage, Business, Business, general, Economics
Abstract

Several unit roots and cointegration tests are conducted to analyze the properties of the utility function exhibited by a competitive firm under the price, as well as the quantity risk. A comparative analysis of the developed heterogeneous model and the conventional models is also presented.

27. Nonparametric tests for monopsonistic market power exertion

Author

Love, H. Alan and Shumway, C. Richard

Subjects
Monopsonies -- Research, Market share -- Economic aspects, Agricultural industry, Economics
Abstract

A non-parametric deterministic test for monopsonistic market power exertion was developed to determine if the market data was consistent with the postulated market structure. Functional forms for supply or demand need not be indicated in the Varian-influenced test. The nonparametric test was conducted to find out how profit maximization can restore a company's influence on price in certain factor markets. The use of simulated company-level statistics for alternative market structures was proven effective.

35. Aggregation of data and profit maximization in Mexican agriculture

Author

Williams, Shon P. and Shumway, C. Richard

Subjects
Profit -- Economic aspects, Econometrics -- Models, Nonparametric statistics -- Research, Business, Business, general, Economics
Abstract

Nonparametric support for two hypotheses related to econometric model specification is analyzed relative to maximizing profit in Mexican agriculture. Results of nonparametric tests for behavioral goal and aggregation level of production data are reported. Evidence does not argue against the hypothesis that producers behave as a group as though they are a price-taking, profit-maximizing firm. Empirical results also support exhaustive aggregation of input categories. Aggregation possibilities in outputs are fewer and are very sensitive to the rejection standard., Nonparametric support for two important hypotheses relevant to econometric model specification is examined. Results of various nonparametric tests for behavioural objective and aggregation level of Mexican agricultural production data are [...]

37. Review of Productivity Accounts

Author

Shumway, C. Richard, Fraumeni, Barbara M., Fulginiti, Lilyan E., Samuels, Jon D., and Stefanou, Spiro E.

Subjects
Productivity Analysis, Shumway, C. Richard, Production Economics, Agricultural and Food Policy, Fulginiti, Lilyan E, Stefanou, Spiro E, Fraumeni, Barbara M, Samuels, Jon D
Abstract

The USDA Economic Research Service has developed national and state-level agricultural productivity measures. These productivity measures are widely referred to and used, and international sectoral comparisons rely on the ERS production accounts for foundation methodology in constructing agricultural productivity accounts in other countries. ERS engaged an external review committee to examine the data sources, methodology, ongoing research, documentation, and reporting of the ERS agricultural productivity accounts. This report represents the outcome of that review.

38. Endogenous regional agricultural production technologies

Author

Fawson, Chris and Shumway, C. Richard

Subjects
Agricultural productivity -- Analysis, Agriculture -- Economic aspects, Business, Business, general, Economics
Abstract

The technical relationships among six productive factors for 10 agricultural production regions in the US are investigated. Among these factors are hired labor, machinery, energy, fertilizer and pesticides (chemicals), feed, seed, livestock and materials. Results indicate that changes in time and several other factors have a significant effect on the region's agricultural production technology.
