Production risk in multi-output industries: estimates from Norwegian dairy farms

Abstract

Abstract-Farmers who produce multiple outputs are portfolio managers in the sense that they use inputs to balance expected economic return and variance of return. This paper estimates the structure of the stochastic multi-output production technology in Norwegian dairy farming, allowing for a more flexible specification of the technology than previous studies. We find that an increase in input levels leads primarily to higher output variability, and that inputs also influence the covariance of shocks between outputs. Riskreducing effects of inputs on outputs are primarily present in the covariance functions. Technical change leads to shifts in the profit distribution over the data period, but no welfare improvement for risk-averse farmers.

Production Risk and Technical Efficiency in Organic and Conventional Agriculture – The Case of Arable Farms in Germany

“…This warrants a more in-depth investigation of cropping choices as a determinant of risk and efficiency. Such research would require estimating a multiple-output technology along the lines of Tveteras et al (2011) combined with a heteroscedastic output distance function approach. Second, the focus on physical output variability as a measure of risk ignores market risks both on the input and output side.…”

“…A risk‐averse producer selects the quantity of inputs x based on actual or expected prices for inputs r and outputs p as well as knowledge of the risky technology so as to maximise expected utility. The solution for maximising expected utility is described in Tveteras et al. (2011) by the following indirect utility function: …”

Determinants of downside risk exposure of dairy farms

“…Dairy producers face a number of risks, such as volatile quantities and qualities of outputs, institutional risks and fluctuating market prices (e.g., Chen et al, 2006, D'Antoni and Mishra, 2012, Henry et al, 2016, Valvekar et al, 2011, Wolf et al, 2009. Production risks have been identified as crucial (Berentsen et al, 2012, Chen et al, 2006, El Benni and Finger, 2013, Orea and Wall 2012, Tveteras et al, 2011 and are assumed to be driven by two main factors. Firstly, climatic variability and extreme climatic events affect the quantity and quality of animal products, such as milk and meat (e.g., Kadzere et al, 2002, Key and Sneeringer 2014, Tubiello et al, 2007.…”

Investigating Yield Variability and Inefficiency in Rice Production: A Case Study in Central China

“…The presence of risks not only affect yield but also producers' behavior with regard to input use [19]. Facing the uncertainties in production, farmers will try to mitigate these risks through input choices, since they are generally risk-averse [18]. However, inputs can either increase or reduce the level of output variance (production risk) but this effect is regional, environmental, and situation-specific [20,21].…”

“…Grain production is inherently risky resulting in wide variability in yield [17] due to biophysical factors, such as weather, soil, and diseases [18]. The presence of risks not only affect yield but also producers' behavior with regard to input use [19].…”
