An empirical comparison of different risk measures in portfolio optimization AgEcon
Hoe, Lam Weng; Saiful Hafizah, Jaaman; Zaidi, Isa.
Risk is one of the important parameters in portfolio optimization problem. Since the introduction of the mean-variance model, variance has become the most common risk measure used by practitioners and researchers in portfolio optimization. However, the mean-variance model relies strictly on the assumptions that assets returns are multivariate normally distributed or investors have a quadratic utility function. Many studies have proposed different risk measures to overcome the drawbacks of variance. The purpose of this paper is to discuss and compare the portfolio compositions and performances of four different portfolio optimization models employing different risk measures, specifically the variance, absolute deviation, minimax and semi-variance. Results...

Park, Seong Cheol; Cho, Jaesung; Bevers, Stanley J.; Amosson, Stephen H.; Rudd, Jackie C..
Selecting the best wheat varieties affects producers’ profit and financial risk. This study identifies the optimal wheat variety selection using the portfolio approach at various risk aversion levels. Results showed that the optimal wheat variety selection was significantly affected by changes in levels of risk aversion of decision makers

Land O' Lakes AgEcon
Boland, Michael A.; Amanor-Boadu, Vincent; Barton, David G..
The case begins with an examination of Land O' Lakes' diversified portfolio of businesses. The business had undergone significant changes since 1998 - it dominated market share in butter and deli cheese, had become the largest crop protection, plant nutrient, and feed manufacturer in the US, and was the fourth largest US seed company. Land O'Lakes used mergers, joint ventures, acquisitions of public and private firms, and divestitures/closing of assets to restructure its portfolio to build its portfolio. The main issue was to evaluate its diversified portfolio of businesses and find ways to improve future performance.

STRUCTURAL CHANGE IN HIGHER EDUCATION: IMPLICATIONS FOR AGRICULTURAL ECONOMICS ACADEMIC PROGRAMS AgEcon
Connor, Larry J..
Major changes affecting Agricultural Economics include: level and sources of funding, increased accountability, a renewed emphasis on teaching, increasing university and college linkages, an evolving student base, and the continuing adoption of educational technology. Major implications include: broader faculty teaching involvement, agribusiness program development, expanding multidisciplinary majors, Ph.D program modifications for teacher preparation, expanding professional M.S. degrees, graduate program size and specialization reductions, alternative financing of graduate education, and faculty training in teaching methods. Teaching represents a major growth opportunity for Agricultural Economics, but it remains to be seen whether the discipline takes...

Lessons for the Forest Service from State Trust Land Management Experience AgEcon
Fairfax, Sally.
This paper argues that state trust land management experience is potentially a source of valuable insights and examples for the U.S. Forest Service. The paper sketches historic and current trends in public resource administration to define what constitutes useful new ideas which might aid the agency in its present crisis. In spite of being this nation's oldest approach to public resource management, the state trust lands are an appropriate source of new ideas in an era in which, the paper suggests: (1) the courts are receding as a major source of executive accountability, (2) the legitimacy of federal agencies, particularly those whose authority is rooted in science, is declining, and (3) the institutional framework for public resource management is...

Portfolios of Agricultural Market Advisory Services: How Much Diversification is Enough? AgEcon
Cabrini, Silvina M.; Stark, Brian G.; Irwin, Scott H.; Good, Darrel L.; Martines-Filho, Joao Gomes.
This study analyzes the potential risk-reduction gains from naïve diversification among market advisory services for corn and soybeans. The total possible decrease in risk through naïve diversification is small, mainly because advisory prices are highly correlated on average. Moreover, because marginal risk-reduction benefits decrease rapidly with size and the cost of holding the portfolios increases linearly due to services’ subscription fees, it is optimal to limit portfolio size to a few advisory programs. Based on certainty equivalent measures and two representative risk-aversion levels, preferred portfolio sizes are between one and three programs.

Futuros agropecuários em portfólios de máxima utilidade esperada AgEcon
Silveira, Rodrigo Lanna Franco da; Barros, Geraldo Sant'Ana de Camargo.
This study investigates the composition of maximum expected utility portfolio, considering stocks, bonds, gold, dollar and agricultural futures contract, between August of 1994 and December of 2007. From the optimal combinations of risk-return (calculated by Markowitz algorithm) and the use of a quadratic utility function (with different levels of risk aversion), were obtained portfolios that maximizes expected utility. The commodity futures were not present in the maximum expected utility portfolios for the complete period, 1994-2000. However, with division of sample in two and three periods, the commodity futures were included in these portfolios during the 2000s. Furthermore, in general, with the risk aversion increase, the participation of these papers...

Use of crops and livestock futures contracts in portfolios: an analysis of feasibility Rev. Econ. Sociol. Rural
Mattos,Fabio L.; Ferreira Filho,Joaquim Bento de Souza.
According to Portfolio Theory, by combining assets that show a correlation inferior to one (1) among their individual returns, it becomes possible to create portfolios that reduce risk without damaging expected return. Crop and livestock futures contracts and company stocks show such a characteristic, which signals potential benefits when forming portfolios combining these two types of assets. This investment strategy is not often utilized in Brazil. The purpose of our research was to assess whether such an asset combination is actually advantageous to those creating investment portfolios in the Brazilian market. Our evaluation used instruments of analysis developed by Markowitz in Portfolio Theory and data about the return from crop and livestock futures...
