Price transmission asymmetry of selected fishes in Bangladesh: An econometric and value chain analysis

Learning the extent of price volatility is critical to ensure the producer and consumer’s economic welfare. Hence, we have envisioned assessing the price transmission relationship over time among the farmgate, wholesale, and retail markets for the four major aquaculture products, namely Rui, Catla, Tilapia and Pangas in Bangladesh. The Granger causality test examined the causal relationships among the farmgate, wholesale and retail fish prices. The Houck/Ward and error correction approach was also applied to study their price transmission pattern. Results indicate that the retail price leads the wholesale and farmgate price. In most cases, the coefficient of variation decreases as the fish handover from the farmgate to retail levels. Out of 15 pairs of farmgate, wholesale, and retail price-series analyzed, 14 pairs are co-integrated (p < 0.01). Current results also suggest that the price transmission pattern is symmetric in the short run but could be a mixture of symmetric and asymmetric in the long run. This asymmetric price behavior indicates that changes in retail prices do not get reflected fully at both farmgate and wholesale prices, and the transmitted prices may vary according to the retail prices based on their rising or falling pattern.

PRICE INTERDEPENDENCE IN THE INTERNATIONAL AND BRAZILIAN BEEF CATTLE MARKET

The objective of this study is to verify the interdependence and asymmetry in price transmission between the main Brazilian and international slaughter beef cattle markets. We used for causality and cointegration tests, and the application of the multiple regression model to analyse the asymmetry in price transmission between the main Brazilian and international markets. The results showed that there is an interdependent relationship between the prices of live cattle in the Brazilian market and the prices of beef cattle in international markets. However, the direction of transmission between them is significant only from the prices of live cattle in the main Brazilian markets to the prices of beef cattle in international markets.

Asymmetry in Gasoline Price Transmission: How do Fuel Pricing Strategy and the Ethanol Addition Mandate Affect Consumers?

This work aims at verifying the existence of asymmetries in gasoline price transmission between refining, distribution, and gas stations. The analysis covers two moments: before (2006-2016) and after (2016-2020) the new fuel pricing strategy adopted in the refining sector. Before 2016, gasoline prices in refineries were stable due to price intervention. After that, prices fluctuated in convergence with the international market. In this paper, we also consider ethanol prices. Due to an addition mandate, ethanol prices influence gasoline price' dynamics. Our hypothesis is that there are “rocket” and “feather” patterns. This means that positive changes in costs are rapidly and fully transmitted to prices, while negative cost changes tend to be transmitted gradually. As a consequence, there is a cost for consumers. We use Dynamic Ordinary Least Squares estimators and Error Correction Models to test the presence of asymmetries and Cumulative Response Functions to measure consumer cost. Results confirm an asymmetric price transmission and indicate that the new pricing strategy has changed the readjustment dynamic. Although we detect asymmetries in both periods, the new pricing strategy proved to be better for consumers, as social costs decreased after its adoption.

Changes in the Price of Food and Agricultural Raw Materials in Poland in the Context of the European Union Accession

Shaping of prices of agricultural raw materials results from the impact of a wide range of factors that influence prices in different links in the marketing chain. Political changes, especially sudden ones, which abruptly changed farming conditions, were one of the reasons for the asymmetry in price transmission. The main purpose of the paper was to estimate the trends in changes in agricultural raw materials prices in comparison to the trends in food prices in Poland in two time frames, differing in political and economic conditions: before (1999–2004) and after Poland’s accession (2005–2019) to the European Union. It was found that the accession to the EU improved the situation of farmers in agricultural markets. There was a reversal of downward price trends in agricultural raw materials and their stabilization. In the years 1995–2005, for most of the prices of agricultural raw materials and food under the analysis, the differences between the trends were not statistically significant. This situation was consistent with the model of market operating under perfect competition. The trends in the prices of wheat, rolls, and bread, as well as the prices of livestock for slaughter-pigs and roast beef were the only exceptions. In turn, in the years 2005–2019 statistically significant differences between the trends in the prices of agricultural raw materials and food were recorded for wheat, bread, and flour; milk, butter, and cottage cheese; eggs and egg retail prices; as well as livestock for slaughter, cattle, and sausages. No statistically significant differences were found for the remaining relationships of the analyzed prices of agricultural raw materials and food. These data indicate a different level of price transmission depending on the product group.

Asymmetry and transmission of international price shocks of cocoa and coffee in Togo

This study assesses the mechanism of the transmission of international price shocks to producer prices of coffee and cocoa in Togo. A threshold autoregressive (TAR) model was estimated using monthly series of international and producer prices of coffee and cocoa in Togo from 1994 to 2018. The results show that there is asymmetric transmission of international price shocks to producer prices. Domestic prices respond less quickly to international price increase than decreases. The asymmetric price transmission is similar in term of the speed of adjustment for the two commodities. In order to deal with this phenomenon, further investigations need to be done to detect the reasons for the asymmetry in price transmission between domestic and international coffee and cocoa markets.

Price transmission in milk supply chain in Ukraine

Purpose. The purpose of the study, which results are submitted in the article, is to analyze the vertical price transmission along the milk supply chain in Ukraine and identify whether this price transmission is symmetric or asymmetric in terms of direction, magnitude, speed. &#x0D; Methodology / approach. To achieve the purpose of the study, we used the following research methods: logical operations (analysis, synthesis, induction, deduction) – to determine the structure of the milk supply chain, to make conclusions about main findings; the correlation analysis – to identify the tightness of links between farm’, processors’ and retailers’ prices; the trend modelling – to build the functions of the trend of prices of different levels of the milk supply chain; the regression modelling – to construct the regression functions of prices of downstream sectors of the milk supply chain; graphic – for visual presentation of main tendencies, pricing and price dynamics in the milk supply chain. The research was performed on the basis of the statistical data of the State Statistics Service of Ukraine for 2013–2020.&#x0D; Results. This paper presents the empirical evidence of asymmetric price transmission along the milk supply chain in Ukraine. The results of modelling proved asymmetric magnitudes of price growth at the organizational and technological stages of the milk supply chain: in the case of the farm prices of raw milk increase the processors’ and retailers’ prices grow up by a much bigger magnitude. There is no leg in price transmission in the milk supply chain, the price shocks at the farm level instantly pass to processors’ and retailers’ prices. The evidence of asymmetry of price transmission testifies the weaknesses of the market positions of farmers and consumers in the milk supply chain in Ukraine, points out the threats for the food security and sustainable development of all agents of this chain. &#x0D; Originality / scientific novelty. For the first time, the quantitative assessments of the magnitude and speed of the price changes in the process of price transmission in the milk supply chain in Ukraine were obtained. The asymmetry of the magnitudes of the vertical price transmission in the milk supply chain in Ukraine was identified. The hostage position of farmers in the case of price shocks was further proved.&#x0D; Practical value / implications. This paper provides a better understanding of arrangements of market forces in the milk supply chain, the consequences of price chocks in the upstream sector of the milk supply chain. The practical value is the methodological and empirical support for the development of regulative measures to improve the milk supply chain’s functioning and sustain food security. Assessment and analysis of the mechanism of price transmission reveals the weak parts of the food supply chain, contributing to the scientific foundation of elaborating the necessary policy actions for harmonization of relations between producers of different stages of the milk chain.

Testing for asymmetric cointegration of Italian agricultural commodities prices: Evidence from the futures-spot market relationship

The volatility of food prices still raises concerns among agricultural market players, increasing interest in the futures markets, thus calling for a better understanding of the connection between the futures and the Italian spot prices. This study uses symmetric and asymmetric vector error correction models to investigate the relationship between futures and spot prices for the Italian agricultural markets of soybean, corn, and milling wheat. The results confirm the leading role of the futures contract prices for all the considered commodities. Moreover, the non-linear cointegration analysis results suggest price transmission's asymmetries for all the agricultural commodity prices. This research provides critical insight into the shape of the futures-spot price transmission.

Asymmetry in Price Transmission: Evidence from the Wheat-Flour Supply Chain in Russia

Price volatility has serious implications for economic welfare of various agents in the grain supply chain. The paper examines asymmetric price transmission along the wheat producer-processor supply chain in Russia using log-transformed monthly prices during the period of 2000-2019. Having specified linear asymmetric vector error correction model, we exposed the long-term cumulative asymmetry in price transmission, however, the hypothesis of short-term symmetry presence failed to reject. The analysis revealed dominant position for wheat producers and wholesalers over the wheat processors. Imperfect competition and their resulting market power, as well as the existence of a huge number of illegal processors are the main causes for asymmetric price transmission on the Russian wheat market.

Price Transmission in Yam Markets in Côte d’Ivoire

Many studies have shown that rising prices are not transmitted in the same way as falling prices and vice versa. There is an asymmetry in price transmission between agricultural commodity markets that is an important issue in household food security. The main objective of this study is to examine the nature of price transmission in yam markets in C&amp;ocirc;te d&amp;rsquo;Ivoire. To do so, two regression models were used, namely the Ordinary Least Squares (OLS) method and Vector autoregressive (VAR) model. The results revealed that a variation in prices on Abengourou and Korhogo markets affects the price on the Abidjan market even though trade between these markets is not direct. Similarly, the price one month later on Abidjan market is affected by its past price and that of Korhogo market one month earlier. As recommendation, the study suggests that the government should strengthen and improve road infrastructure as well as communication networks to enhance trade between markets.

This paper aims to examines the relationships of prices between Indonesia and major importer countries. The causality are analysed by Granger Causality used first-differenced data because all series first-differenced stasionary. To analyze the asymmetry of price transmission by error corection model approach. Causality estimeting show that the direction was from Indonesia to major importing countries, USA, Germany, and Japan and no reverse. The Conclusion is that the price transmission of relatonship between Indonesia Coffee prices and coffe prices in USA, Germany and Japan was assymetry adjustment, the falling price was slower than the raising price, but the accumulation adjustment at the falling price was greather than the raising price. Keywords: Price asymmetry, major importing countries, causality, speed adjustment

China-to-FOB price transmission in the rare earth elements market and the end of Chinese export restrictions

This paper investigates the impact of the end of the export quota system (EQS) on China-to-export price transmission in the rare earth elements market, taking into account threshold effects and price transmission asymmetries. The results indicate that export prices became more responsive to changes of Chinese prices after the Chinese Ministry of Commerce (MOFCOM) abandoned the exort quota policy. While price shocks wash out much quicker in the Post-EQS period, we do not find evidence for rockets and feathers-type of behaviour.

Modeling Market Integration and Asymmetric Price Transmission Dynamics of Yam Markets in Ghana

Functioning agricultural markets are fundamental to unlock economic growth and to accelerate agricultural development. Understanding the behavior of agriculture markets is crucial for price, poverty and livelihood policy strategies in agrarian economies. To assess price transmission and market efficiencies of Ghanaian yam markets spatial market integration analysis of five major yam markets: Techiman, Tamale, Wa, Kumasi and Accra was conducted. Monthly wholesale price data between January 2006 and June 2018 were used. Results from the momentum threshold autoregressive (M-TAR) model indicated the presence of co-integration and price transmission asymmetries. Thus, price increases in Techiman reference market are more rapidly transmitted to the other regional markets than price reductions. It is recommended that the source of this type of asymmetry be investigated as it favors middlemen at the expense of producers and retailers/consumers for appropriate marketing policy intervention.

Pricing Efficiency in Agricultural Markets: Evidence from the Sugarcane Sector in Laos

This study aims to analyse the relationship between farm gate prices and export prices in the sugarcane sector in Laos. The Johansen cointegration test, Granger-causality test, and the Error Correction Model (ECM) were used to investigate the causality and asymmetry of price transmission between the two market levels. The coefficient of variation values shows that farm gate prices were more volatile than prices at the exporter level. Granger’s causality tests show two-way causality between farm and export markets. Further, estimates of the price adjustment process suggest an asymmetric adjustment between producer and exporter prices, in short and long-run. This implies that there is a non-competitive market structure. It is therefore recommended that policies be put in place to ensure the efficient marketing of sugarcane in Laos.

Market Integration and Price Transmission in the Vertical Supply Chain of Rice: An Evidence from Bangladesh

As a staple food, rice has an enormous market in Bangladesh in terms of market participants and the volume of the product. As the price of rice is always a sensitive factor for producers, poor consumers and policy makers, this paper investigates market integration and price transmission along the vertical supply chain of rice. Johansen’s test of co-integration confirmed that farm, wholesale and retail prices are co-integrated in the long-run. A causality test revealed that prices were found to be at wholesale levels for both the upstream and downstream markets. The asymmetry error correction model (ECM) has discovered short-run and long-run asymmetry in price transmission in the vertical supply chain where both producers and consumers were being affected due to positive and negative asymmetry. Threshold autoregressive (TAR) and momentum threshold autoregressive (M-TAR) models have confirmed threshold co-integration as well as threshold effect on asymmetry in price transmission. The results highlight the inevitability of policy implementations and increased public interventions to reduce asymmetry for engendering greater pricing efficiency in Bangladesh rice markets.

Analysis of Dairy Product Price Transmission in Hungary: A Nonlinear ARDL Model

This paper addresses the assessment of the price transmission of dairy products in Hungary. Monthly prices are used in testing the hypothesis of asymmetric price transmission between farmers and retailers. The magnitude of short- and long-run asymmetric transmission between price levels is measured through a nonlinear autoregressive distributed model (NARDL). The cointegration of variables is validated through bounds test of the NARDL model. The estimated NARDL model proves the existence of long- and short-run asymmetric relationships between producer milk price and most retailer dairy product prices. Furthermore, the model confirms the presence of a significantly positive long-run price asymmetry for butter, buttercream, sour cream, and Trappista cheese. The positive long-run price transmission asymmetry results could be explained by the strong market power of milk processors, which are granted through their concentrations and the absence of competitiveness in the market. The short-run asymmetry of price transmission could be explained by implementing some policy interventions, such as the milk quotas, which limit milk production. Analyzing the asymmetric relationship between the producer milk price and the retailer dairy product prices could give a clear vision of the dairy sector and how prices move between market actors, highlighting the retailers’ purchasing power feature, and its role in determining the market price interaction.

European gasoline markets: price transmission asymmetries in mean and variance

ABSTRACT The main objective of this article is to analyse the different sources of asymmetric price transmissions in the fuel market for France, Germany and Spain. During the last decades, the EU has carried out several common energy policies to achieve more efficient and competitive markets. However, given the specific characteristics of each country, the question we want to address is if fuel prices across EU members behave differently in response to different market structures. Oil operators have been targeted by competition authorities for conducting non-competitive practices. To figure out whether the common complaint that gasoline prices adjust differently to positive or negative input price changes, dynamic asymmetric models for the mean and variance are developed for each country. Several asymmetric specifications for the mean and variance are considered. The best specification combines double threshold error correction models (DT-ECM) for the mean with asymmetric EGARCH plus an asymmetric dummy variable for the conditional variance. We show that French gasoline prices behave more competitively, adjusting quicker to the long-run equilibrium and with more price volatility. This outcome is consistent with the strong presence of hypermarkets following low-cost pricing strategies in France.

Analysis of price transmission in the beef value chain using a calculated retail carcass price

ABSTRACTThe large difference between the producer price of a beef carcass and the retail prices of individual beef cuts has raised concerns among producers. These concerns are caused by the possibility of asymmetry in the market. This study examines the price transmission mechanisms in the beef market by comparing the weekly producer carcass price with a weekly calculated retail carcass price, instead of average retail prices, over a period of three years. It further estimates the causality links between the producer and retail prices. The traditional and standardised augmented Dickey–Fuller procedures were used to test for co-integration and asymmetry in price transmission. Four competing models, namely the Engle–Granger, threshold autoregressive (TAR), momentum threshold autoregressive (M-TAR) and momentum consistent TAR models, were applied. The results indicated that there is positive asymmetric price transmission between producer and retail price as retailers in the market respond quicker to shocks that squeeze their margin than those that stretch them. Market information was found to be flowing from the producer to the retailer.

Vertical price transmission in the Nigerian cowpea market

Purpose The purpose of this paper is to examine the asymmetry of vertical price transmission (i.e. from the wholesale to the retail market) in the Nigerian cowpea market and identify its causes. Design/methodology/approach The authors surveyed 19 markets in Kano and Ibadan from 2012 to 2015. The autoregressive distributed lag model and asymmetric error correction model were adopted to test the asymmetry of vertical price transmission. Findings Results suggest that price transmission in Kano is symmetric, but it is asymmetric in Ibadan. This distinction is caused by the differences in the market structure (in terms of competition level, inventory period and transaction cost) of these cities. Originality/value This is the first study to empirically investigate the vertical price transmission in two Nigerian cowpea markets. It is also the first to reveal the role of the market structure in price transmission through a comparison of two markets. The findings provide policy implications and will help create a more efficient food market in Nigeria.

Asymmetric price transmission in the Hungarian retail electricity market

The article compares the market power of Hungarian electricity traders during the partially liberalised transitional market model from 2004 to 2008 and the fully liberalised period lasting since 2008. In our empirical work, we use an econometric modelling technique based on asymmetric price transmission (APT) theory to measure the market power of traders in the electricity market. The aim of our work is to conduct a quantitative analysis of the Hungarian electricity trading market by applying the APT modelling technique – used widely in agro-economic analyses – to electricity markets. The intuition behind the method is the assumption that asymmetric price transmission refers to deviations from perfect competition. The research has found that different regulation regimes lead to different patterns of asymmetry in price transmission and the results underline that the market position of electricity traders have improved since the introduction of the liberalised market model. By mapping the results of the APT model to the actual policy and market changes we argue that the APT method is a useful tool for analysing the competition on electricity markets.
