The Value of Dairy Quota under a Commercial Export Milk Program

This paper argues that under a commercial export milk program, the market value of quota will be determined by the spread between the domestic market price and the export price, rather than the conventional wisdom that it is determined by the spread between the domestic milk price and the marginal cost of production. Under this new economy, it is argued that ultimately the market price of dairy quota will be priced independently of firm marginal costs, which implies that low-cost (or high-margin) producers will not hold an economic advantage in bidding for quota over higher-cost producers. Regression results are consistent with the hypothesized positive relationship between quota values and the difference between domestic and export milk price. The average export price has generally increased over time and is approximately equal to the marginal cost for an average producer. The results have implications for a World Trade Organization (WTO) challenge. New Zealand and the United States feel the domestic program acts as an export subsidy by cross-subsidizing production of commercial export milk. The results here suggest that the prices for the filled export contracts are approximately the marginal cost of production for the average producer and not lower, as suggested by the challenge. Export contracts were found to have higher price risk than domestically produced milk. The risk is compounded by the short-term nature of most export contracts. The increase in risk for the commercial export milk program (CEM) implies that it is unlikely many farmers will greatly diversify into CEM contracts unless the uncertainty is reduced.     

Importance of Standardizing Raw Milk Quality for the Enhancement of Croatian Market Competitiveness

In the European Union member states (EU), it is necessary to evaluate hygienic condition of milk in order to determine milk price. Similar requirement was set by the Republic of Croatia in 2000. The Rulebook defines minimal quality criteria that fresh raw milk must have in order to be purchased. Upon completion of analysis, milk is classified into quality classes, each having a defined price. Increased value of somatic cell count (higher than 400,000/ml) and micro ogranism (MO; higher than 100,000/ml) directly decreases the raw milk price, whereas higher content of fat and protein causes its increase. Since the system of market milk price formation was established, producers have been stimulated to produce milk of higher quality: in a total of milk being purchased, the highest quality milk share increased from 23.3% to 34.2%. Referring to a trend of milk purchase price reduction in the EU, and considering the current high milk purchase price in Croatia, Croatian producers have an opportunity to improve conditions in milk industry before the country joins the EU. Current milk production needs to be increased and milk quality also needs to be improved in order to make Croatian milk production more competitive on the European and world market.     

The role of retail market power and state regulations in the heterogeneity of farm‐retail price transmission of private label and branded products

Given the leading role of private label brands in the fluid milk market, it is of special interest to focus on possible differences in farm‐retail price transmission between private label and branded milk as well as the causes of heterogeneity. This article examines the heterogeneous effects of private label and branded products on price transmission in the fluid milk market using a panel threshold asymmetric error correction model. Results indicate that upward retail‐price adjustment is faster than the downward price adjustment for both private label and branded milk. The speed of adjustment of private label products is significantly faster than branded products in three different price regimes. We further investigate the reasons of heterogeneity in farm‐retail price transmission of private label milk. We find that both retailer market power and state pricing regulations contribute to the heterogeneity in asymmetric price transmission. Higher retailer market power causes retail prices of private label milk to rise faster and to fall slower. The existence of a state pricing regulation slows down the adjustment speed of retail prices of private labels back to the long‐run equilibrium, regardless of whether the retail price is low or high.     

New Futures Markets in Agricultural Production Rights: Possibilities and Constraints for the British and Dutch Milk Quota Markets

Farms are increasingly being affected by policies that involve production rights. Because of fluctuations in the prices of these rights in the spot market, farmers face a price risk. Establishing a futures market might enable them to hedge against this price risk. Rights futures have some features that differ from those of traditional commodity futures. This makes them an effective and efficient tool for managing price risk. The implications of these findings will be illustrated for milk quotas in the United Kingdom and The Netherlands. Prior conditions which might make a futures market for milk quotas successful in both countries will be deduced.     

POPULATION DYNAMICS AND MILK SUPPLY RESPONSE IN THE US LAKE STATES

This paper develops a dynamic model of a dairy cow population and of milk supply response. When applied to the US Lake States, the model provides evidence against the Nerlovian model. It suggests that the pattern of dynamic effects of prices on cow numbers varies for different prices. The estimated dynamic supply elasticities provide some useful information on the nature of dairy production adjustments. For example, the response of milk supply to market prices is found to be very inelastic in the short run. It takes at least 7 years of sustained change to obtain an elastic response to milk price. Also, feed price and slaughter cow price are found to have smaller effects on dairy supply than milk price, but larger effects than risk, hay price or capital cost.     

Demand for wild edible mushrooms. The case of Lactarius deliciosus in Barcelona (Spain)

Wild edible mushroom demand has increased substantially in OECD countries in the last few years. Nevertheless, few studies have been published in recent years on these markets. The main objective of this paper is to characterise the saffron milk cap (Lactarius deliciosus Fr.) demand in Spain. Data sources in this study come from main Central Markets in Spain. Using econometric methods, we have found that the consequence of an increase in the price of the saffron milk cap has a negative effect on demand. However, changes in the percentage of persons born in Catalonia every year exercise a positive effect, and price increases in the Madrid market could also induce an increase in the Lactarius deliciosus demand in the Barcelona Central Market. The consequences of chanterelle imports on the Catalan demand for the saffron milk cap appear to be negative. Finally, results indicate that the saffron milk cap and oyster mushroom behave as complementary goods and, therefore, consumption of one of these mushrooms reinforces the other's consumption.     

Product Labeling and Economic Value of Milk Market Segmentation

Abstract

This study explores the economic benefit from labeling milk and milk products and its impact on the supply and demand for fluid milk. The empirical estimate measures the economic value of milk market segmentation based on consumers' willingness to pay for hormonefree milk. The study uses survey data from Kansas households and applied a Probit model for willingness-to-pay and an ordinary least square model for demand analysis. The empirical results show that as long as consumers are willing to pay a higher price for bSTfree milk society would benefit from milk market segmentation.     

Political Market Power Reflected in Milk Pricing Regulations

We investigate revealed political market power reflected in the pattern of price discrimination by end use that is the hallmark of U.S. milk marketing orders. We show that the pattern of prices that would maximize producer profits, if producers operated a cartel with monopoly power in a regional market, is far above actual government-set price differentials between milk used for fluid products and that used for manufactured products. The pattern of actual price differentials is consistent with political welfare weights for producers relative to consumers that are small compared to the weights that would yield maximum producer profits.     

Maize acreage response under differential prices in the Republic of Benin,West Africa

Price response of maize acreage in Benin was estimated with a particular emphasis on whether the prices were producer prices in rural markets or retail prices in urban markets. A second difference between prices was examined through a price adjustment model which takes into account the distortions caused by local units on maize price when one is concerned with the pricing system in the private marketing network relating rural and urban areas. Urban market price specification appeared to be the most relevant statistically in explaining acreage decisions in Mono province. Price elasticity of acreage was 0.445 in this area while its value, around 0.10, was not significant for Benin as a whole. The use of adjusted urban prices enabled an increase of 5.6% of the elasticity in Mono province. The urban vs. rural difference was apparent, but the coefficients of the price variable were not significant in equations with rural prices. The latter were not as reliable as those of the urban market of Dantokpa (in Cotonou city) collected by the Institute of Statistics (INSAE) and the GTZ project.     

Strategic pricing in a differentiated product oligopoly model: fluid milk in Boston

In an imperfectly competitive industry, differentiated products compete with each other with price rather than quantity as the strategic variable. Several previous studies have employed a generalized Nash–Bertrand model: Liang (1989) , Cotterill (1994) , Cotterill et al. (2000) , and Kinoshita et al. (2002) ; however, only Liang has explored the theoretical foundations of that model. This article generalizes the Liang two‐good model to three goods. A surprising and important result follows. Price‐conjectural variations do not exist in models with three or more goods. Price‐reaction functions, however, exist in multiple‐good models. We estimate them jointly with a brand‐level demand system to evaluate the total impact of a brand manager's price change on own quantity. In a differentiated product market, this is a useful addition to a partial demand elasticity approach, because a change in one brand's price typically engenders a price reaction by other brands that affects own quantity via substantial cross‐price elasticities among substitutes. Strategic pricing in the Boston fluid milk market was also influenced by the existence of a raw milk price support program, the Northeast Dairy Compact. We find that the advent of the Compact was a focal point event that crystallized a shift away from Nash–Bertrand to more cooperative pricing. If the downstream market is not competitive, one needs to consider strategic price reactions when designing and evaluating agricultural price programs.     

Tracing the evolution of the aggregate U.S. milk supply elasticity using a herd dynamics model

The U.S. dairy sector is characterized by increasing volatility of milk prices, and consolidation in production as evidenced by declining number of dairy farms with an increasingly larger share of milk supplied from a small number of very large farms. Using aggregate national data, we build a mixed‐frequency herd dynamics econometric model of the U.S. milk supply that updates and substantially amends the model first proposed by Chavas and Klemme. We implement a dynamic residual‐based bootstrap technique that can be used in testing for changes in nonmarginal simulated long‐run supply responsiveness, and trace the evolution of long‐run milk supply elasticity from 1975 through 2010. Several papers in the past have suggested that long‐run supply elasticity increases with dairy farm size, which implies that increased importance of large farms would increase aggregate long‐run supply responsiveness. Contrary to this conclusion, we find a declining trend in long‐run supply elasticity from 1975 through 2005. Persistence of such a decline would be a major cause for worry, as ever larger price swings would be needed to equilibrate the market in face of demand shocks. However, we find that milk supply is becoming more responsive since 2005 both to milk and feed price changes. Increasing responsiveness to feed prices further justifies focusing the next generation of the dairy policy instruments on managing dairy profit margins rather than just revenue streams.     

On farmland prices and rents in Japan

Historically, the Japanese farmland market has been strongly regulated, although fundamental changes in policy were introduced in 1967 and 1980. This article examines the relationship between farmland prices and rents in Japan for 1955–2000 using the cointegration procedure of Johansen et al. (2000) , which admits structural breaks. Results show the presence of a cointegrating relationship with a significant break in 1980. There is Granger‐causality from prices to rents, which suggests that rents are determined within an institutional setting according to farmland prices. The rent–price elasticity is unity, which supports the notion of efficiency in the farmland market.     

Markups,organic agriculture and downstream concentration at the example of European dairy farmers

A competitive environment, highly concentrated processing and retailing sectors as well as increasing decoupling of direct payments from production volumes and the area under cultivation incentivizes farmers to find alternative ways to improve their bargaining position towards downstream companies. This article explores the possibilities of organic agriculture to enhance the bargaining power of farmers along with the role of concentration in downstream industries. Using a dataset with more than 200,000 observations from approximately 40,000 dairy farms, I estimate markups of price over marginal cost in dairy farming as a measure of market power in the EU. The results show that organic farmers achieve a significant markup premium over conventional farmers. With increasing market shares of organic milk in total milk production markups of conventional farmers diminish whereas those of organic farmers are unaffected. Farm-level markups decrease with increasing market shares of medium-sized dairy processors and increase with increasing market shares of large processors. The presence of large multinational retail chains shows an adverse impact on farmers’ markups.     

Price linkages in the international skim milk powder market: empirical evidence from nonparametric and time‐varying copulas

The objective of this article is to assess the integration of the international skim milk powder (SMP) market. This is pursued using monthly data over 2001 to 2014 from the three principal SMP‐producing regions (the EU, the USA and Oceania) and nonparametric kernel‐based and time‐varying copulas. The empirical results point to a strong and an increasing degree of overall price co‐movement and to statistically significant probabilities for joint price crashes and booms. While the EU and Oceania have been the regions with the highest degree of integration, the USA has been catching up with them.     

Demand for dairy products in Mexico

Mexico is the world's largest importer of non-fat dry milk (NFDM) and imports of cheese, fluid milk, and whey have increased rapidly in the past four years. In the wake of GATT and the NAFTA, as well as recent economic developments in Mexico, world dairy markets will be affected as a result of changes in the Mexican dairy sector. The study analyzes both domestic and import demand for dairy products in Mexico to determine price and income elasticities as well as import elasticities. The results indicate that the demand for fluid milk is the most responsive to price changes and NFDM demand is inelastic with respect to its own price. There is little subtitution between fluid milk and non-fat dry milk, although fluid milk is relatively elastic, which suggests the existence of other substitutes for fluid milk. Estimation of import demand equations reveal similar trends in response to price changes, but income elasticity of imports was highest for fluid milk which suggests that Mexico will import possibly more fluid than dry milk as incomes rise. The exchange rate was the most significant variable influencing all dairy product imports.     

Expected Economic Effects of BST in The Netherlands

The calculated profitability of using Bovine Somatotropin (BST) on typical dairy farms in The Netherlands ranges from Dfl.160 to 300 per cow per year, assuming 1985 prices and circumstances, and ignoring the costs of BST. A 20% increase in milk production and no change of the feed/milk relation were used for the calculations. BST is more profitable on intensive farms or on farms with more opportunities for alternative uses of land, buildings and labour. The quota system, however, leads to a considerable reduction of profitability. At a national level, and with an unchanged milk price, a 28% adoption rate of BST would increase national income about Dfl.120 million. However, the cost of BST or any decrease in milk price could reduce this amount, even to below zero. It is apparent that some dairy farmers who apply BST will earn more income whereas others will lose income.     

产业链视角下乳制品价格溢出效应研究——基于VAR-BEKK-GARCH(1,1)模型

奶业产业链是乳制品价格形成的基础,从产业链着手有助于发现乳制品价格溢出效应的本质特征。本文选取牛奶、酸奶、婴幼儿奶粉、老年奶粉作为乳制品的代表,基于2010年5月至2018年5月乳制品产业链月度价格数据,使用VAR-BEKK-GARCH(1,1)模型分析乳制品产业链各环节间的价格溢出效应。研究发现:婴幼儿奶粉产业链上、中、下游价格间存在显著的单向均值溢出效应,而牛奶、酸奶、老年奶粉产业链的中游对上游、下游对中游价格存在显著的单向均值溢出效应;牛奶、酸奶、婴幼儿奶粉、老年奶粉产业链各环节价格在自身和彼此间具有显著双向波动溢出效应,但从显著性水平来看,牛奶产业链和婴幼儿奶粉产业链各环节间的双向波动溢出效应最为明显。     

Landscape patterns of development under two alternative scenarios: Implications for conservation

The spatial pattern of urban development has important ecological and conservation implications. Urban sprawl, characterized by scattered and low-density urban development, is commonly criticized for its negative ecological impact. In response, growth management policies have been proposed in order to promote compact development, which is generally considered more favorable from an ecological perspective. Spatial simulations of land cover change are useful for comparing urban development scenarios and their potential effects. One aspect that has not received much attention is how the rate of development may affect differences between compact development and urban sprawl in terms of their potential impact to biodiversity conservation at the landscape scale. Our goal in this study was to compare the spatial pattern and landscape-scale conservation and ecological implications of sprawling development (expected under unregulated development) versus compact development (promoted by growth management policies) at different development rates. We focused on Israel's Mediterranean region—a region characterized by high human population density and heterogeneous land cover. Using a cellular automata model, DINAMICA-EGO, we calibrated and validated an urban development model for the period between 1998 and 2007. Using this period as a reference, we simulated two scenarios 20 years into the future: unregulated (resulting in a more sprawling development pattern) versus regulated development (resulting in a more compact development pattern). For each scenario we analyzed a range of development rates, and compared built-up area patterns, and several landscape-level attributes of natural habitats, conservation priority areas, and protected areas. We found that at development rates comparable to those observed during 1998–2007, there was no major difference between the two scenarios. At higher development rates, some differences between the scenarios emerged: natural core areas were more fragmented and smaller in their extent, and a higher proportion of conservation priority areas were expected to undergo development in the unregulated scenario. Overall, the regulated scenario was more favorable for conservation. Since the regulated and unregulated scenarios exhibited only minor differences in lower development rates, modifications to policy measures included in the regulated scenario should be considered in order improve its effectiveness.
