Risk programming and sparse data: how to get more reliable results (2008)

Hardaker, J.B., Lien, G., Richardson, W., Hegrenes, A.

Because relevant historical data for farms are inevitably sparse, most risk programming studies rely on few observations. We discuss how to use available information to derive an appropriate...

Economic sustainability and risk efficiency of organic versus conventional cropping systems (2006)

Lein, G, Hardaker, J B, Flaten, O

Environmental, social and economic attributes are important for the sustainability of a farming system. Resilience is also important yet has seldom been directly considered in evaluations of economic...

Lein, G, Hardaker, J B, Flaten, O

Environmental, social and economic attributes are important for the sustainability of a farming system. Resilience is also important yet has seldom been directly considered in evaluations of economic...

Sharing risks in agriculture; principles and empirical results (2001)

J.B. Hardaker, A.A. Dijkhuizen

The risk environment of farmers is changing. For example, price and production risks are increasing and governments increasingly encourage agriculture to find private market solutions for...

J.B. Hardaker, A.A. Dijkhuizen

The risk environment of farmers is changing. For example, price and production risks are increasing and governments increasingly encourage agriculture to find private market solutions for...

Whole-farm planning under uncertainty : impacts of subsidy scheme and utility function on portfolio choice in Norwegian agriculture (2001)

Lien, G., Hardaker, J.B.

This paper addresses the impacts of degree of risk aversion, subsidy scheme and choice of utility function on optimal farm plans in Norwegian agriculture. Data from a farm business survey (1991-1997)...

Sharing risks in agriculture : principles and empirical results (2001)

Meuwissen, M.P.M., Hardaker, J.B., Huirne, R.B.M., Dijkhuizen, A.A.

The risk environment of farmers is changing. For example, price and production risks are increasing and governments increasingly encourage agriculture to find private market solutions for...

Risk and risk management in agriculture : an overview and empirical results (2000)

Huirne, R.B.M., Meuwissen, M.P.M., Hardaker, J.B., Anderson, J.R.

The paper gives an overview of sources of risk and risk management strategies in agriculture. As risk is an inescapable fact of life, in particular in agriculture, farmers must try to manage risk...

A multi-attribute utility model to optimise sow replacement decisions (1998)

HUIRNE, R. B. M., HARDAKER, J. B.

An existing stochastic dynamic programming model is expanded so that its output can be used as input to a multi-attribute utility model to determine the optimal replacement policy in swine breeding...

The formulation of MOTAD programming models for farm planning using subjectively elicited activity net revenue distributions (1979)

HARDAKER, J. B., TRONCOSO, J. L.

If activity net revenue distributions for farm planning under risk are subjectively assessed, the claimed advantages of MOT AD (Minimisation Of Total Absolute Deviation) programming can be reaped...

A Multi-Attribute Utility Model to Optimise Sow Replacement Decisions.

Huirne, R B M, Hardaker, J B

An existing stochastic dynamic programming model is expanded so that its output can be used as input to a multi-attribute utility model to determine the optimal replacement policy in swine breeding...

PERCEPTIONS OF RISKS AND RISK MANAGEMENT STRATEGIES; AN ANALYSIS OF DUTCH LIVESTOCK FARMERS

Meuwissen, M.P.M., Huirne, R.B.M., Hardaker, J.B.

The risk environment of farmers is changing and new risk management strategies are being introduced. Beal (1996) stated that risk management strategies adopted by farmers will be in accordance with...

ASSESSMENT OF THE OUTPUT OF A STOCHASTIC DECISION MODEL

Hardaker, J.B., Tanago, A.G.

The concept of stochastic dominance is described and its use is illustrated in relation to the evaluation of the output of a systems simulation model of lucerne haymaking in south-west Spain. Two...

OPTIMAL FEEDING POLICIES FOR BROILER PRODUCTION: AN APPLICATION OF DYNAMIC PROGRAMMING

Kennedy, J.O.S., Rofe, B.H., Greig, I.D., Hardaker, J.B.

The determination of an optimal feeding and selling strategy for broiler production given a space constraint is formulated as a dynamic programming problem. Production equations derived from trial...

FARM SYNDICATION AND RISK SHARING: A CASE STUDY

Bartholomaeus, M.K., Hardaker, J.B.

The effectiveness of fully integrated group farming as a means of permitting farmers to achieve economies by working together and to share risk is investigated using two case-study farms from the...

THE INTEGRATED USE OF SIMULATION AND STOCHASTIC PROGRAMMING FOR WHOLE FARM PLANNING UNDER RISK

Trebeck, D.B., Hardaker, J.B.

Methods of whole-farm planning under risk are briefly reviewed, noting especially associated operational problems. A planning problem relating to spatial diversification of beef production in the...

Recent Developments in Farm Planning: Sub-Optimal Programming Methods for Practical Farm Planning

Powell, R.A., Hardaker, J.B.

This paper discusses the use of sub-optimal programming techniques in farm management. The scope for employing such techniques to derive farm plans which more closely conform to farmers' real...

An Appreciation of Decision Analysis in Management

Anderson, J.R., Hardaker, J.B.

Decision analysis, the practice of Bernoullian decision theory and Bayesian statistics, is reviewed in relation to its application in management. Aspects of the scaling of beliefs (probabilities) and...

An Economic Evaluation of the Footrot Eradication Program in the New England Region of New South Wales

Carmody, M.J., Hardaker, J.B., Powell, R.A., Everett, R.E.

An assessment is presented of the costs and benefits of a scheme in the New England region of New South Wales for the control of footrot in sheep. An ex post evaluation is presented of the operation...
