This study investigates the impact of trade liberalisation on the spatial price co‐movements between the dairy markets of the EU, Oceania, and the United States. We consider two main dairy products, namely butter and whole milk powder (WMP), and employ R‐Vines to assess the development of the tail dependence between the price series. We split the time span (i.e. 2000‐2017) in December 2007 to capture the change in the tail dependence as well as in the potential of each region to act as the central market. Our findings indicate that the EU acts as the central market for butter in both sub‐periods, whereas the EU succeeds Oceania in acting as the central market for WMP from the first sub‐period to the next. Further findings highlight slightly increasing tail dependence in the butter market and in the WMP market for the EU‐OCE and EU‐US pairs. However, the tail dependence for the WMP prices between Oceania and the United States weakens, in which we attribute to the 2013 Chinese ban on milk powder imports from Oceania.

The PISA results with regards to Mathematics and Science for the Greek students have been alarming in multiple consecutive reports. Drawing from this experience, we focus on cultivating the basic geometric understanding of the individual and create a series of constructive and discovery-learning exercises, in order to facilitate the learning process. In this context, we develop an exercise intended for students between ten and twelve years of age. The exercise guides the students to identify geometrical shapes in a background and subsequently to observe and conceptualize basic properties of the triangle (e.g., the sum of the angles of a triangle). The exercise is in digital format and is implemented through educational platforms, thus allowing students to practice in an engaging environment.

The 2003 CAP Reform commenced a liberal shift on the policies designed to protect farmers across Europe. The CAP Health Check of 2008 and the 2013 CAP Reform confirmed this change, adopting measures including the further decoupling of production, the abolishment of set-aside and the phasing-out of milk quotas. It is therefore expected that price transmission has been affected radically. This study investigates the price transmission mechanism along the European food supply chain, based on an asymmetric panel vector error correction model (VECM). Panel data on agricultural commodity (farmer), producer (processor) and consumer (retailer) prices from nineteen European countries are considered. The sample is split into two sub-periods, before and after the CAP Health Check, to examine how the price transmission mechanism has been affected. Cointegration is confirmed among the price series through the Pedroni tests and the long-run relationship is obtained with two estimation methods (i. e. fully modified OLS and dynamic OLS). Prior to the CAP Health Check, positive asymmetry is detected from farmer to processor and from processor to retailer. However, after the CAP Health Check price transmission becomes symmetric, thus suggesting that decreased support has resulted in a more efficient price transmission mechanism.
