Abstract

This article attempts to verify the phenomenon of price transmission between wholesale markets of carrots in Poland. Determining the level of spatial integration of markets will indicate their efficiency and thus can make it easier for producers to take decisions about where to sell their products. The empirical data includes daily quotations of carrot prices on fruit and vegetable wholesale markets in Bronisze, Kalisz, Poznań, Radom and Sandomierz. The time range of the studies covered the years 2011–2016. This research is based on dynamic econometric methods (sVAR model) and the Granger causality tests. The research carried out using dynamic econometric methods has shown that despite the occurrence of significant variation in the level of carrot prices in the examined markets, their interaction was observed. Moreover, the results of the sVAR model estimation indicate that the changes in carrot prices on a particular market are stronger influenced by the price changes from the same market. This is an autoregressive effect. It also means that the carrot price information coming from other wholesale markets (price transmission effect) has a much weaker effect.

波兰蔬菜批发市场空间一体化的选择实例
本文试图验证波兰胡萝卜批发市场之间的价格传导现象。确定市场的空间一体化水平将表明其效率,从而使生产者更容易决定在何处销售其产品。实证数据包括Bronisze、Kalisz、poznaz、Radom和Sandomierz水果和蔬菜批发市场胡萝卜的每日报价。研究的时间范围为2011-2016年。本研究基于动态计量经济学方法(sVAR模型)和格兰杰因果检验。使用动态计量经济学方法进行的研究表明,尽管在所调查的市场中胡萝卜价格水平发生了显著变化,但它们的相互作用是可以观察到的。此外,sVAR模型估计的结果表明,特定市场上的胡萝卜价格变化受同一市场价格变化的影响更大。这是一种自回归效应。这也意味着来自其他批发市场的胡萝卜价格信息(价格传导效应)的影响要弱得多。
