Última The value of market uncertainty in a livestock epidemic AgEcon Niemi, Jarkko K.; Lehtonen, Heikki. Introduction of foot and mouth disease (FMD) into country typically initiates eradication procedures which remove animals from the market, and halts the export of livestock products from the infected country. The magnitude of these effects can be highly uncertain. This paper presents a stochastic dynamic programming model which simulates possible market implications of alternative FMD and export scenarios in the Finnish pig sector. It takes into account dynamics and adjustment of the animal stock, price movements and uncertainty related to the duration of the trade ban. Results suggest that losses to pig producers can increase considerably when the risk of prolonged export ban increases. Production adjustments also strengthen. Consumers can gain from a...

Ano: 2011 URL: http://purl.umn.edu/103688 Insure or Invest in Green Technologies to Protect Against Adverse Weather Events? AgEcon Pietola, Kyosti; Myyra, Sami; Niemi, Jarkko K.; Van Asseldonk, Marcel A.P.M.. This paper analyses investments in green technologies when insurance is also an option. Green technologies are defined to have the power to increase productivity and decrease volatility of future revenues. The insurance options involve the scale and coverage either in a yield insurance or in an index insurance. The stochastic process is a combination of insurable stationary short-run process and non-stationary long run process. The optimal decision rules are solved numerically by stochastic dynamic programming. The results suggest that the index insurance maintains market based incentives to invest in green technologies whereas a yield insurance substantially decreases investments, as expected. An actuarially fair yield insurance decreases investments at...

Ano: 2011 URL: http://purl.umn.edu/100738 MODELLING THE DYNAMICS OF PRODUCTION ADJUSTMENT TO SHORT-TERM MARKET SHOCKS AgEcon Niemi, Jarkko K.; Lehtonen, Heikki. Models of agricultural economics typically operate at an annual basis or in a static equilibrium framework where inputs, outputs and their prices may change considerably. Production dynamics, however, imply that models relying on spatial and temporal aggregation do not capture the effects of biological constraints in the short run. This paper examines short and long-term impacts of demand and production cost shocks in the pig sector. The analysis is carried out with a dynamic programming model which takes into account changes in export and domestic demand and market clearing price. It optimizes the supply of piglets on a monthly basis. Econometric techniques are used to estimate demand functions. Short-term negative market shocks can already have...

Ano: 2008 URL: http://purl.umn.edu/6401 Market implications of FMD epidemics in the Finnish pig sector: Does market structure matter? AgEcon Niemi, Jarkko K.; Lehtonen, Heikki; Lyytikainen, Tapani; Kallio, E.. This paper examines the role of market coordination and market distortions caused by a hypothetical FMD outbreak in the Finnish pig sector. By using stochastic dynamic programming, it simulates the consequences of two outbreak scenarios (large vs. small) under two distinct market regimes (competitive market vs. monopoly in the domestic supply). Simulated losses depend on the magnitude of outbreak and expected duration of possible turndown of meat exports, whereas market regime has a limited impact.

Ano: 2008 URL: http://purl.umn.edu/43837 Price volatility and return on pig fattening under different price- quantity contract regimes AgEcon Niemi, Jarkko K.; Liu, Xing; Pietola, Kyosti. The goal of this study is to estimate how different price or quantity fixing contracts affect the value of pig space unit in pig fattening. The value of pig space unit is estimated with a stochastic dynamic programming algorithm. The model maximises the value of pig space unit by using four decision variables. The input-output ratios are endogenous and the option to suspend production temporarily is taken into account in the model. The results suggests that the smooth functioning of markets in Finland can be promoted by ensuring that price changes are transmitted smoothly between input and output markets, and that producers are compensated for giving up the option to suspend production temporarily in the event if unfavourable market situation. Instead of... Tipo: Conference Paper or Presentation Palavras-chave: Demand and Price Analysis; Livestock Production/Industries.

Ano: 2010 URL: http://purl.umn.edu/61591 Risk Classification in Animal Disease Prevention: Who Benefits from Differentiated Policy? AgEcon Niemi, Jarkko K.; Lyytikainen, Tapani; Sahlstrom, Leena; Virtanen, Terhi; Lehtonen, Heikki. Risk classification of livestock farms can help stakeholders design and implement risk management measures according to the possessed risk. Our goal is to examine how differently pig farms may contribute to the societal costs of an animal disease outbreak, how valuable this information is to different stakeholders, and how it can be used to target risk management measures. We show that the costs of an outbreak starting from a certain farm can be quantified for the entire sector using bio-economic models. In further studies, this quantified risk can be differentiated so that farms and slaughterhouses internalise the full cost of risk in production decisions and inhibit animal densities, animal contact structures or other characteristics which pose a threat...
