In this paper, option-pricing theory is applied to an investment problem in hog production. A stochastic simulation model capable of pricing American-type options is developed. This is achieved by recursive calculation of the exercise frontier. The model is used to determine the investment trigger and the disinvestment trigger for a pig-fattening barn under German market conditions. It turns out that the investment trigger, taking into account the value of waiting in an uncertain environment, can be considerably higher compared to classical investment criteria such as the net present value. This offers an explanation as to why farmers are indeed reluctant to invest in hog production. Another finding is the sensitivity of the option prices with respect to the stochastic process that is assumed for revenues and variable costs of the production activity.  相似文献

The Quebec hog/pork industry has grown significantly over the last 25 years. Explanations of this growth in the literature have centered on government policies, expansion of profitable market opportunities, and reforms in marketing institutions. A coincident index model that trends with total hog slaughters in Quebec is estimated using a dynamic factor model. It implicitly defines a variable that measures the overall state of economic activity in the Quebec hog/pork industry. The results show that reforms in hog marketing institutions are strongly correlated with the economic expansion of the industry. A leading economic index also forecasts the growth of the coincident index using leading variables. The overall statistical performance of the leading coincident index is disappointing, but the growth in American inventories of frozen pork meat is shown to have useful predictive value.  相似文献

This article applies the Band‐Threshold Autoregression (Band‐TAR) model to investigate whether the law of one price (LOOP) holds in Taiwanese wholesale hog markets during the period from May 1987 through December 2003. We find evidence of a nonlinear mean reversion in deviations from the LOOP for relative hog prices. Our empirical study confirms the presence of thresholds and provides strong evidence in support of the view that the regional hog markets have been tightly integrated in Taiwan and that the wholesale hog market in Taiwan is an efficient market economy. Furthermore, the estimated half‐lives from the nonlinear generalized impulse response analysis are as short as four months.  相似文献

Specification of quota licenses as quasi-fixed inputs in a multi-variate flexible accelerator model of dynamic input adjustment reveals supply management's effect on Alberta dairy investment patterns and, thereby, on total factor productivity growth. Estimates of a dynamic dual model of Alberta dairy, using panel data from 1975–91, show that strong complementarity between cattle and quota licenses results in short-run cattle adjustments that are opposite in direction from the long-run adjustments. A model of total factor productivity growth under dynamic input adjustment shows that the distortions to cattle investment caused by investing in quota licenses adversely affects productivity growth. As a result, there is likely to be a significant understatement of single-period estimates of the cost of supply management in the dairy sector.  相似文献

This article addresses the issues of investment/disinvestment asymmetry and a possible existence of a sluggish regime in the demand for a quasi-fixed input in the U.S. hog production sector. Adopting a new threshold estimation procedure, quarterly data from 1970 through 2002 are used to estimate a regime-dependent investment demand equation for a quasi-fixed input, taking sows as a proxy. The results support the existence of three regimes over alternative specifications precluding the sluggish regime, confirming the existence of asset fixity in hog production. The results also highlight the importance of accounting for investment rigidity when estimating hog supply and variable input demands.  相似文献

The paper develops a comparative statics model of long‐run industry equilibrium in the presence of size‐based environmental regulation stringency and applies the model to the U.S. hog industry. The economic model shows that when size‐based environmental stringency is also size biased, large farms downsize, expand, or do neither depending on how environmental stringency shifts their marginal production cost relative to their average cost. Empirical testing using data from the top‐ten hog‐producing states suggests that environmental regulation stringency has limited impact on small farms and leads to a reduction in the number of large farms. Results cannot reject positive size bias at the farm level due to the stringency of environmental regulation.  相似文献

This paper analyses the investment behaviour of Russian farms during the period of economic stabilisation that followed Russia’s financial crisis of 1998, and is the first to apply the error‐correction investment model to describe farms’ investment behaviour in the transitional context. Additionally, the paper employs the error‐correction and the adjustment‐cost model to test for differences in the investment behaviour between various farm categories. The results show that in general Russian farms exhibited an error‐correcting behaviour in the period under investigation. From 1999 to 2005 the output–capital gap was closed by an average rate of 10% per year. Estimates of the adjustment‐cost model show that Russian farm investments are very sensitive to the sales–capital ratio, suggesting that Russian farms exhibit increasing returns to scale and positive expectations about future revenues. Yet, such farm characteristics as ownership structure, access to input markets and also regional specifics were found to be decisive for farm investment not only in the short but long term too. Finally, the results show that the adjustment‐cost model is adequate for the evaluation of differences in short‐term investment behaviour, whereas it is noticeably less powerful for investigating differences in the farms’ long‐term investment behaviour.  相似文献

In this paper a simple model is developed in which the piglet price serves as a forecast for the hog price 3 months ahead. The model is tested on data from Northern Europe, viz. Norway, Sweden, Denmark and Finland during the period 1982-1992. The empirical results lend strong support to the hypothesis that hog producers hold rational expectations when pricing the piglets. Thus, the weight adjusted piglet price typically represents an unbiased (conditional) forecast with unsystematic errors for the hog price one quarter later.  相似文献

Antimicrobial drugs are fed to hogs at subtherapeutic levels to prevent disease and promote growth. However, there is concern that the presence of antimicrobial drugs in hog feed is a factor promoting the development of antimicrobial drug-resistant bacteria. This study uses a treatment-effects sample-selection model to examine the impact that feeding antibiotics has on the productivity of U.S. hog operations. No relationship was found between productivity and antibiotics fed during finishing, but productivity was significantly improved when antibiotics were fed to nursery pigs. Restrictions on feeding antimicrobial drugs during the nursery phase would likely impose significant economic costs on U.S. hog producers.  相似文献

The objective of this study is to investigate the nature of risk preferences of Quebec dairy and hog producers. The direct elicitation of utility method is employed to determine producers'degree of risk aversion. The Delphi process is used to obtain more refined and realistic responses. The results reveal that the risk preferences of the randomly selected Quebec farmers are highly diverse. The percentage of risk-taking farmers ranges from 8% to 23% depending upon the level of investment and the nature of the enterprise. On average, the majority of farmers in both groups are found to be risk averse. Based on the differences between the means as well as distributions, although not significant in all cases, hog producers are found to be consistently more risk averse than dairy producers. Moreover, the gap between the two groups widens as the level of investment increases. The implications of this result are that the stability of farm income due to supply management in dairy sector may facilitate investments of a given risk (for example, adoption of a new technology) more so than it would in the hog sector.  相似文献

Canada's hog sector has faced two decades of tumultuous growth, yet there are no recent estimates of supply response. This study uses state‐space methods to account for a multiplicity of autonomous structural changes impacting the sector and determines if the fundamental relationship between supply response and hog prices has changed from previous estimates. The results are consistent with prior research but offer the reader previously unavailable estimates of supply response with respect to feed prices and the variability of hog and feed prices. Feed price elasticities are somewhat larger than hog price elasticities. The effects of price risk for supply response appear quite muted but the impacts of feed price risk are greater than for hog price risk.  相似文献

Many investment decisions of agribusiness firms, such as when to invest in an emerging market or whether to expand the capacity of the firm, involve irreversible investment and uncertainty about demand, cost or competition. This paper uses an option‐value model to examine the factors affecting an agribusiness firm's decision whether and how much to invest in an emerging market under demand uncertainty. Demand uncertainty and irreversibility of investment make investment less desirable than the net present value (NPV) rule indicates. The inactive firm is more reluctant to enter the market when it takes into account demand uncertainty because it preserves the opportunity of making a better investment later. The active firm is more reluctant to abandon the investment because there is an option value of keeping the operation alive. There is a greater distance between the entry and exit thresholds under the option‐value approach than under the NPV rule due to demand uncertainty. The results have implications for agribusiness decision‐making.  相似文献

Farm‐level adaptation to changing economic environments is often slower than expected. Technological innovations, for instance, are frequently adopted at a later date than the net present value of investment suggests. This can be explained by a model of “investment under uncertainty,” which consistently accounts for uncertainty, sunk costs, and the flexibility of investment timing. Its essential conclusion is that, due to temporal opportunity costs, critical incremental cash flows that trigger investments might be higher than those needed for simple cost recovery. This accounts for an ostensible reluctance to invest (economic hysteresis). In this article, we demonstrate how slow conversion to organic farming in general, and the different rates of conversion in Germany and Austria in particular, can be explained by the new investment theory.  相似文献

Investment decisions are not only characterised by irreversibility and uncertainty but also by flexibility with regard to the timing of the investment. This paper describes how stochastic simulation can be successfully integrated into a backward recursive programming approach in the context of flexible investment planning. We apply this hybrid approach to a marketing question from primary production which can be viewed as an investment problem: should grain farmers purchase sales contracts which guarantee fixed product prices over the next 10 years? The model results support the conclusion from dynamic investment theory that it is essential to take simultaneously account of uncertainty and flexibility.  相似文献
