This paper describes the structure of the small-ruminant trade in southwest Nigeria, analyses the factors determining the price of animals, and examines the relationship of prices between markets. Animals imported from the north dominate the sheep and goat trades, and supply and prices are highly seasonal. However, multiple regression shows animal prices to be largely predictable in terms of the characteristics of the animal (breed, sex and live-weight) and the market in which it is sold (location and month of sale). Prices are relatively closely correlated between markets over time, and price relationships between markets reflect the respective structures of the trade in northern and southern animals. Price margins between markets reflect the level of traders' commission and storage costs in addition to the direct costs of transport. The study concludes that there is no evidence for market inefficiency or segregation, and that there is considerable market potential for increased local production of sheep and goats. In policy terms, the market's efficiency implies that government involvement beyond its present, limited facilitative role would not be justified.  相似文献

This study aimed to explore how producers’ reference prices are formed and adapt over time, and how they affect marketing decisions. Results indicate that producers focus on three major variables to form their reference prices: the current market price, the highest price to date, and their expectation about price behavior. Further, they update their reference prices during the marketing season mainly in response to changes in current market prices, their own expectations about price behavior, and the general price trend. Finally, our findings suggest that producers’ marketing decisions are based on the spread between current market price and reference price, the general market trend and price expectation.  相似文献

A survey of two rural markets in southwest Nigeria over 14 months showed that supplies, sales and prices of sheep and goats varied widely during the period with a sharp peak during the Muslim festival of' Eid-el-Kabir and a smaller peak during the Christmas-New Year period. Local West African Dwarf (WAD) sheep and goats and northern Y'ankasa sheep and Red Sokoto goats were traded in the markets and animals were purchased for rearing, trading, ceremonies, butchering/catering, sacrifice, and festivals. There were significant differences between species/breeds purchased for various purposes. A hedonic price model was fitted to determine factors influencing price. After adjustments were made for age, weight, sex, time of transaction and market, WAD sheep commanded higher prices than WAD goats and Red Sokoto goats for all purposes except for butchering/catering; Red Sokoto goats commanded similar or lower prices than WAD goats depending on the purpose for purchase; and Y'ankasa sheep, principally purchased for the Eid-el-Kabir festival, commanded marginally higher prices than WAD sheep. The market share of WAD sheep is currently small and is under competition from northern sheep and goats, so increased production of WAD sheep in the south will benefit both producers and consumers in the area. In general, the results indicate that buyers have preferences for specific breeds and species for specific purposes, so producers and sellers may benefit by targeting specific buyer categories and times of the year.  相似文献

A sheep market survey was undertaken to determine the effects of certain animal and market characteristics on price and the pattern of sheep prices in relation to seasons. Nine key Ethiopian central highlands markets were surveyed for a period of one year in 1989. Each market was surveyed once a week on the main market day. Price, weight, sex, age, colour, condition score, breed type and buyer's purpose were recorded for all completed transactions as well as the numbers offered and sold on each market day. A total of 50062 cases were recorded. Three markets, each representing redistributive, intermediate and terminal markets, as identified by the distribution in buyer's purpose were chosen for further analysis. Considerable weekly price variation was evident in these markets. Prices were also seasonal with higher premiums paid during some religious festivals. Animal characteristics (weight, age, condition, sex, colour) as well as buyer's purpose and seasons were variably important in explaining variation in price among animals within weeks. Variations in the composition of these characteristics from week-to-wcek were among factors underlying changes in weekly mean prices. R2 varied from 0.2659 to 0.3583 in the quadratic price per kg model and from 0.7822 to 0.8413 in the quadratic price per head model in the three markets. However, it was found that price per head was predicted equally well overall by estimated price per kg multiplied by actual weights and that because of wide variation in weights, both within and between weeks, price per kg is more useful market information.  相似文献

Understanding how producers make decisions to allot acreage among crops and how decisions about land use are affected by changes in prices and their volatility is fundamental for predicting the supply of staple crops and, hence, assessing the global food supply situation. This study makes estimations of monthly (i.e., seasonal) versus annual global acreage response models for the world's principal staple food crops: wheat, corn, soybeans, and rice. Primary emphasis is given to the magnitude and speed of the allocation process. Estimation of intra‐annual acreage elasticity is crucial for expected food supply and for input demand, especially in the light of the recent short‐term volatility in food prices. The econometric results indicate that global crop acreage responds to crop prices and price risks, input costs as well as a time trend. Depending on respective crop, short‐run elasticities are about 0.05 to 0.40; price volatility tends to reduce acreage for some of the crops; comparison of the annual and the monthly acreage response elasticities suggests that acreage adjusts seasonally around the globe to new information and expectations. Given the seasonality of agriculture, time is of an essence for acreage response. The analysis indicates that acreage allocation is more sensitive to prices in the northern hemisphere spring than in winter and the response varies across months.  相似文献

Livestock markets influence income generation for producers, but also accessibility and affordability of highly nutritious animal-sourced foods for consumers. Despite their importance, the functioning of livestock markets in lower-income countries is poorly understood and rarely studied compared to more developed countries. This study analyzes wholesale cattle markets in Ethiopia using a uniquely rich large-scale dataset covering both prices and cattle characteristics in 39 markets (in both highland and lowland areas) over a 10-year period, and hedonic regression models structured to understand both cattle price formation and seasonal and secular price dynamics. We show that cattle prices are influenced by a wide range of factors, including proxies for meat quality, religious fasting practices, climate-based seasonality but also climate shocks and availability of grazing land, competition from animal traction services, and rising consumer incomes. However, the implied effects of these factors are often significantly different in highland mixed crop-livestock areas compared to agro-pastoralist lowland areas, emphasizing the dualistic nature of cattle markets in Ethiopia. The analyses help inform the systemic challenges that Ethiopia will need to overcome to meet rising demand for beef products in the face of sustained income and population growth, as well as the adverse effects of climate change.  相似文献

The Pricing of Experience Goods: The Example of en primeur Wine   总被引:1,自引:0,他引:1  
The market for "primeur" wine in the Bordeaux region allows producers to sell wine that is still in barrels. As with all experience goods, producers send quality signals to uninformed buyers. Using original data on Bordeaux wines, we show that the pricing behavior of producers depends to a large extent on their reputation, and much less on short-term changes in quality (as measured by experts' grades). We also find that the primeur price has an informative role, since a 10% increase in primeur price leads to a 3% increase in prices on the market for bottled wine.  相似文献

Whether farmers form price expectations adaptively or in a forward-looking manner has implications for supply response analysis and for the implementation of agricultural policy reform. This paper examines the formation of price expectations by Kenyan export-crop farmers who market their produce through a monopsonistic parastatal. The analysis allows for relaxation of the small-country assumption within a rational expectations framework. Production behavior is consistent with expectations of future prices based on indicators of aggregate supply and of the marketing board's purchasing capacity. The finding that price forecasts may be formed using information other than previous price levels implies that marketing reforms that raise prices may not raise the relevant price expectations. To elicit a positive supply response, market reforms should be sensitive to farmers' interpretation of institutional signals as well as previous prices.  相似文献

A wide range of empirical studies show the extent to which the rise of supermarkets in developing countries transforms domestic marketing channels. In many countries, the exclusion of small producers from so‐called dynamic marketing channels (that is, remunerative ones) has become a concern. Based on data collected in Turkey in 2007 at the producer and the wholesale market levels, we show that intermediaries are important to understanding the impact of downstream restructuring (supermarkets) on upstream decisions (producers). Results show first that producers are not aware of the final buyer of their produce, because intermediaries hinder the visibility of the marketing channel, thereby restricting a producer's choice to that of the first intermediary. Econometric results show that producers who are indirectly linked to the supermarkets are more sensitive to their requirements in terms of quality and packaging than to the price premia compensating the effort made to meet standards. Therefore, the results lead us to question the role of the wholesale market agents who act as a buffer in the chain and protect small producers from negative shocks, but who stop positive shocks as well, and thereby reduce incentives.  相似文献

Variations in producer prices over time cause constant fluctuations in farm incomes. In this study, the author uses a game theory approach to determine the economically optimal time to sell dried figs for the agricultural firms that produce them. Based on the price producers received in the period between August 2003 and July 2010, dried fig prices were converted into 2003 real price levels. According to a linear programming model based on these assumptions, it was determined that the best time for producers to sell dried figs, with the rate of 26.63%, was November and December.  相似文献

This article examines how corn prices affect the demand for feed grains and the supply of livestock outputs. The differential approach to the theory of the multiproduct firm is employed to examine ex ante decisions about feed grain demand and livestock supply. The estimation results suggest that livestock producers have little flexibility in adjusting the demand for corn in response to an increase in corn prices. The substitutable relationship between corn and distillers’ grains contributes to alleviating pressures on feed costs in response to high corn prices. In addition, the estimation results highlight that the composition of livestock supply can be altered by changes in livestock prices. On the basis of the estimated elasticities, the decompositions of profit‐maximizing input demand are conducted to examine the effects of changes in corn prices on feed grain demand and livestock supply. The decomposition results reveal that an increase in corn prices reduces corn demand but raises the demand for distillers’ grains mainly due to the substitution effects of corn price changes. The decomposition results also show that an increase in the price of corn reduces cattle supply but raises the supply of chicken and pork due to the output relationships in supply.  相似文献

Consumption of livestock products in Southeast Asia could continue to increase rapidly, as has been the case in Northeast Asia. The extent to which domestic producers may respond to these demand developments will be influenced by government interventions in both livestock product and feeds markets. The paper analyses the net contribution of livestock product and feed price distortions on the effective rate of protection, and whether intervention in the commodity market is augmented or offset by intervention in the feeds market. While policy-induced distortions were found to exist in the livestock sectors of Thailand and Malaysia, especially in beef and dairy production, the contribution of feeds policies to these distortions was minimal. In contrast implicit taxes on feeds were high in Indonesia and the Philippines. In the latter, support on product prices was sufficient to more than offset the tax on feeds so that effective protection remained positive. But in Indonesia both livestock and feeds policies worked to provide disincentives to livestock production. It is concluded that livestock and feeds policies should be formulated with regard to objectives and priorities within both sectors. This could require that greater emphasis be placed on feeds sector assistance policies that do not affect the price of feeds.  相似文献

Contemporaneous observations on expected supply and on prices of post‐harvest futures contracts for corn are used to estimate expected demand relationships. These equations are used to estimate the prices of the post‐harvest contracts based on new supply estimates. Each estimate can be compared with a corresponding futures price, i.e. the market forecast. The differences help discern the market expectations about the expected demand for the new crop relative to historical experience, which can help support outlook analyses. We find that in recent years, a 100 million bushel change in the expected supply of corn results in about a 6 cent per bushel negative change in the price of December corn. The discussion also deepens understanding of the term ‘anticipatory prices’ as defined by Holbrook Working in his 1958 work.  相似文献

This study assesses the degree of vertical price transmission along the wheat‐bread value chain in Ethiopia. This is pursued by applying a vector error correction model and an impulse response analysis using monthly price data for the period 2000–2015. Our analysis considers transmission of price shocks across different market levels, including from the international and domestic wheat grain markets at the upstream to the domestic wheat bread market at the downstream of the value chain. The empirical findings indicate that significant cointegration exists across prices of the different market stages. There is a transmission from international prices to domestic prices at downstream markets, in particular to flour and bread prices. Prices at upstream markets are largely influenced by the domestic wholesale market. In general, the speed of adjustment is quite slow with a half‐life of about one year for restoring the equilibrium price relationship. As price margins between the different market stages in the value chain have substantially decreased in the last 15 years, higher transmission, and thus exposure to international market shocks, can be expected in the future. The results also show that causal relationships exist between prices at different market stages—with the wholesale market identified as the key market level where prices and price expectations are formed.  相似文献

This note takes the view that existing studies of the impact of the Agenda 2000 cereal reform package have mis‐specified the impact of this package on a producer's price distribution. It is argued that an accurate assessment of this package requires use of the methodology outlined in Fraser (1991), and that use of this methodology highlights the central role of expected world prices in determining whether producer perceptions of this impact are favourable or unfavourable. A numerical analysis in the context of wheat producers generates an estimate for expected world prices of 111–112 Euros/tonne above which producers will perceive the package favourably. This estimate is found to be robust with respect to the key parameters of the analysis.  相似文献

A formula for deriving the price of segregated early weaned pigs using corn, soybean meal, and market hog prices was estimated by equating return on investment for the different phases of production. USDA reported prices were compared with prices derived from this and several other common formulas. Based on several accuracy measures, the estimated formula was better at predicting spot-market prices than other formulas. Producers appear to form price expectations based on futures plus expected basis rather than simply futures or current cash prices. However, the method of choosing price expectations will depend on the risk attitudes of the buyer and seller and their business relationship. Developing pricing formulas based on the framework outlined here (equal returns on investment) has merit for establishing prices in the absence of publicly reported information. However, it is important that users of the formula understand the conceptual framework of how and why it was developed.  相似文献

Contingent tariffs for agri‐food commodities have been proposed as a Special Safeguard Mechanism (SSM) in the Doha Round negotiations by the G33 group of countries as an instrument to control downward spikes in their border prices and/or surges of imports. The objective is to safeguard the livelihood security of farm households in poor countries. To date, most analysis of such tariffs uses stochastic partial equilibrium models with perfect competition. Yet in many markets for such commodities, imperfectly competitive market intermediaries play an important role in determining producers' prices, as do state trading enterprises (STEs). A stochastic partial equilibrium model of a typical importing country situation is specified in which there are either imperfectly competitive domestic intermediaries with a contingent tariff or an STE. The role of these intermediaries in influencing price behaviour and livelihood security in the presence of contingent tariffs alters the conclusion based on models of perfect competition. Using Monte‐Carlo simulation, it is shown that the efficacy of a contingent tariff is substantially reduced as the number of firms declines because increasingly they absorb the tariff, and the procurement price and producer surplus do not increase to the extent that they do under perfect competition.  相似文献

The hog/pork industry in Quebec has been going through major institutional changes since 1989, the year an electronic auction was put in place to market all of the hogs in the province. Because the auction's ability to generate high prices did not meet the expectations of hog producers, the pure auction system was replaced by a hybrid one in 1994. In this system, most of the hog supply was pre-attributed to processors at a negotiated price based on the US. price while the remainder of the provincial supply of hogs was sold through the auction. In this paper, we investigate how a seemingly inefficient marketing mechanism like pre-attributions can increase the efficiency of a usually efficient mechanism like an auction. We present theoretical arguments regarding the sustainability of collusion under the pure auction and hybrid systems in addition to analyzing auction prices with modern time series tools.  相似文献

We apply a value chain approach to examine how blackberry producers in Ecuador can improve production and marketing practices to obtain more favorable prices. Results show that general upgrading actions are associated with improved producer prices, and specific activities, such as seeking information from reputable sources can lead to substantial welfare improvements. The paper goes beyond most value chain studies which treat participation in a ‘modern’ value chain as a discrete state. Ecuador's blackberry industry is evolving incrementally with no clearly discernible ‘modern’ market chains. Instead, producers incrementally make improvements in multiple dimensions. Relatively low‐cost practices, many of which do not imply substantial risk or investment, are associated with price improvements. Obstacles to participation in incremental value chain upgrading activities are not insurmountable. In particular, scale of production is not a limiting factor: small‐scale producers are not precluded from adopting improved practices and they do not suffer in terms of price received.  相似文献
