Price transmission in the Hungarian vegetable sector AgEcon
Bakucs, Lajos Zoltan; Ferto, Imre; Szabo, Gabor G..
In this paper we analyse price transmission for the carrot, parsley, tomato, green pepper and potato markets. Although there is a dual farm structure dominated by small individual farms, our results imply that price information flows from the producer to the retail level for potatoes, parsley and carrots. Our results also suggest that farmers do not merely accept prices, but can actually influence market prices. Tomato and green pepper prices have large transmission elasticities, and causality runs from the retail to producer level. It therefore follows that tomato and green pepper producers tend to accept prices and that the sector’s prices are determined by upper market levels (processors, wholesalers, retailers). These results are reinforced by the fact...

Volatility in Agriculture Commodity Prices in India: Impact and Macroeconomic and Sector-Specific Policy Responses AgEcon
Bathla, Seema.
Globalization and trade liberalization have exposed agricultural sector of many developing countries to sudden disturbances, caused not just by demand-supply conditions within their economies but also by volatility in global commodity prices, exchange rate and surge in imports. This paper evaluates the magnitude of sensitivity of Indian agriculture to these factors, and explores policy options that may neutralize their adverse effects, maintain price incentives and stability. The analysis is undertaken for one important tradable commodity viz. wheat by applying a structural econometric model, separately under the exportable and importable scenarios from 1980-81 to 2009-10. Findings reveal wheat to be increasingly driven by an incentive structure based on...

Trade Elasticities: The Significance of Trade Barriers, Multinationals and Market Structure AgEcon
Ahmadi-Esfahani, Fredoun Z.; Anderson, Glenn Michael.
The elasticity of price transmission measures the extent to which a change in world prices will be transmitted to an importing country, with an elasticity of less than one being attributed to trade barriers. Recent research highlights the role that multinational trading companies may play in impeding price transmission. Further, in markets characterised by monopolistic competition an estimate of the partial elasticity of demand may be of limited practical value if no account is taken of the reaction of competitors. In this paper the potential for market structure to affect price transmission and trade elasticities is demonstrated. The elasticity of price transmission has been central to a revised approach to estimation of trade elasticities and has been...

Causalidade e transmissão entre os preços de mandioca, trigo, milho e seus derivados no Paraná AgEcon
Alves, Lucilio Rogerio Aparecido; Cardoso, Carlos Estevao Leite; Felipe, Fabio Isaias; Campion, Michele Tubero.
This study aims to analyze the relations of causality and price transmission of the cassava root, the cassava starch, the cassava flour, the wheat, the wheat flour and the corn, in the State of Parana. The used data goes from January 1995 to December 2005, with monthly regularity. It was applied the methodology of Granger causality to test the relations between the variables. The results showed long term relations between corn and cassava root prices, cassava starch and cassava flour prices, wheat and corn prices and wheat and wheat flour prices. It was emphasized the dependence of the cassava root prices in relation to corn, wheat, cassava starch and cassava flour prices and its little influence on these variables. It was also noted that cassava flour...

Price transmission on the Hungarian milk market AgEcon
Bakucs, Lajos Zoltan; Ferto, Imre.
There has been little systematic analysis of the extent to which organic farming policies have influenced growth in the organic sector. Analyses of organic farming policy instruments, for the most part, provide extensive and detailed reviews of instruments applied either in a single country or across countries. Hence, there is a great need to examine systematically whether there is a relationship between the introduction of organic farming policies and the growth of the organic food sector, and whether particular designs of organic farming policies are more effective than others. In this paper, we take the first step in the endeavour of analysing the effects of organic farming by undertaking an econometric analysis of the relationship between organic...

Asymetric Price Transmission in the Spanish Lamb Sector AgEcon
Ben Kaabia, Monia; Gil, Jose Maria.
This paper aims to investigate the non-linear adjustments of prices between farm and retail prices in the lamb sector in Spain. The methodology used is based on the multivariate approach to specify and estimate a three-regime Threshold Autoregressive Model. Results indicate that in the long-run price transmission is perfect and any supply or demand shocks are fully transmitted along the marketing chain. In the short-run, price adjustments between the farm and the retail levels are asymmetric and are representative of a demand-pull transmission mechanism. On the other hand, retailers benefit from any shock, whether positive or negative, that affects supply or demand conditions.

Vertical price transmission between market operators in Hungarian agricultural product chains AgEcon
Varga, Tibor.
Price transmission studies related to the cointegration of price time series are a suitable means for studying market dominance at the various market levels in the food product chains. For this study a price transmission asymmetry study was carried out for 18 commercial food product chains. In this study a monthly price time series was used for the period 2001 to 2005. It was found that there is significant product variation in market dominance which spans the entire industry. However, the variation is not significantly linked to either sectors or vertical levels. At times it is unstable and can easily tilt toward the vertical partner level. Depending on price changes, it can also vary, which, in turn, reflects changes in weather conditions. Following a...

A FONTOSABB HAZAI TERMÉKPÁLYÁK ÁRALKUINAK JELLEMZŐI AgEcon
Varga, Tibor; Tunyogine Nechay, Veronika; Kemeny, Gabor.
A termékpályák tagoltsága, a termékpálya-fázisok eltérő koncentráltságából fakadó piaci formák a tevékenységi láncban kialakult áralkukat, valamint az elérhet ő árnyereséget, illetve árveszteséget meghatározzák. A számítási eredményeket a piac szereplőinek véleményével ütköztető vizsgálataink megerősítik, hogy a termékek túlnyomó részénél az erőfölény a legkoncentráltabb oldalnál, a kereskedelmi fázisban található. A kiskereskedelmi láncok nem csak egyértelműen árvezetők, de egyben a feldolgozott termékek importárain keresztül az egész vertikum áralakulását meghatározzák. A termelői és feldolgozói fázis között – nagyon kevés kivétellel – az árnyereség a feldolgozóknál figyelhető meg. Az ágazati szintű erőfölény vizsgálataink szerint termékenként erősen...

Global Market Shocks and Poverty in Vietnam: The Case of Rice AgEcon
Coxhead, Ian A.; Linh, Vu Hoang; Tam, Le Dong.
World food prices have experienced dramatic increases in recent years. These “shocks” affect food importers and exporters alike. Vietnam is a major exporter of rice, and rice is also a key item in domestic production, employment and consumption. Accordingly, rice price shocks from the world market have general equilibrium impacts and as such, their implications for household welfare are not known ex ante. In this paper we first present a simple framework for understanding the direct and indirect welfare effects of a global market shock of this kind. Second, we quantify the transmission of the price shock from global indicator prices to domestic markets. Third, we then we use an applied general equilibrium (AGE) model to simulate the effects of domestic...

Transmision de precios en los mercados regionales de ovino en Espana AgEcon
Boshnjaku, L.; Ben Kaabia, Monia; Gil, Jose Maria.
Resumen El análisis de las relaciones de precios existentes en un determinado sector permiten, por un lado, ofrecer una idea aproximada del funcionamiento de los mercados y, por otro, anticipar respuestas ante shocks inesperados en mercados relacionados. El objetivo de este estudio se ha centrado en el análisis de la transmisión de precios entre los principales mercados de ovino en España. Para llevar a cabo este estudio se ha adoptado un enfoque econométrico que ha tenido en cuenta las propiedades estocásticas de las series, la posible naturaleza multivariante de los procesos de transmisión, y la distinción entre el comportamiento a corto y largo plazo. Los resultados indican que los mercados de ovino se encuentran bastante interrelacionados pudiéndose...

INTERREGIONAL INTEGRATION OF WHEAT MARKETS IN KAZAKHSTAN AgEcon
Brosig, Stephan; Yakhshilikov, Yorbol.
Reliable marketing opportunities in both interregional and international trade along with relatively low transportation [and transaction] costs are essential to profitability of wheat production. In this study we have investigated one aspect of the quality of marketing and trade opportunities in the Kazakh wheat sector, that is the extent and nature of integration among regional wheat markets. We applied threshold cointegration technique to assess the co-movement between time series of elevator prices at three grain-trading (and producing) spots in the northern and central parts of the country. Results suggest that markets of two northern grain trading spots (Petropavlovsk and Kokshetau) are closely connected with each other while their connection with...

Linking Small Scale Farmers in China with the International Markets: A Case of Apple Export Chains AgEcon
Zhang, Xiaoyong; Qiu, Huanguang; Huang, Zhurong.
This study describes how governance mechanisms were formed that link small-scale apple farmers in China with export markets. These institutional innovations have improved the efficiency of price transmission and generated higher profit margins for various actors in the supply chain, in particular for small-scale farmers. Chinese apple exports are highly coordinated through ongoing long term loyal network relationships and vertical integration. Relevant policy implications and further challenges are discussed in the conclusion.

Spatial Price Transmission in Kazakh Wheat Markets AgEcon
Yakhshilikov, Yorbol; Brosig, Stephan.
Reliable marketing opportunities in both interregional and international trade are an important precondition for further development of the agricultural sector. In this study we assess interregional integration of Kazakh wheat markets. We apply asymmetric threshold error correction models to assess the co-movement of elevator prices at three grain-trading spots in the northern and central parts of the country. Results suggest that markets of two northern grain-trading spots (Petropavlovsk and Kokshetau) are closely connected with each other while their connection with Karaganda in central Kazakhstan is much weaker. Here, levelling out price gaps through arbitrage trade only occurs after a threshold of considerable extent has been surpassed.

Estimation of impact of EU agricultural policies on the world market prices AgEcon
Chantreuil, Frederic; Tabeau, Andrzej A.; van Leeuwen, Myrna.
According to world market studies, the influence of policy measures on the world market price in one or in a limited number of countries is, in general, much less significant than the influence of multilateral policy changes. To investigate the impact of EU agricultural policies on world market prices, we attempt to model the transmission between EU policy and world prices directly via world market price equations, as part of the AGMEMOD model.
