Price dependence among the major EU extra virgin olive oil markets: a time scale analysis

Abstract

The goal of this study is to assess the strength and mode of price dependence by time scale, among the extra virgin olive oil markets of Italy, Spain, and Greece. These three Mediterranean countries are responsible for 95% of olive oil production within the European Union and they account for more than 50% of the olive oil exports worldwide. For the empirical analysis, monthly prices from the aforementioned countries are utilized along with the tools of discrete wavelets and non-parametric copulas. Results indicate that (a) price linkages in the short run are significantly different from those in the longer run, with price dependence being stronger in the longer run, and (b) in the very long run, price shocks of the same sign but of different magnitude are transmitted from Italy to Spain with a higher probability than they are transmitted from Italy to Greece. Accordingly, the time scale affects the intensity as well as the pattern of dependence, pointing this way to asymmetric price co-movement. Regarding the integration of the three markets, the finding of asymmetric co-movement is not consistent with well-integrated markets.

Sonochemical-assisted synthesis of CsPbBr3 perovskite quantum dots using vegetable oils

“…In our study, we prioritized common commercial vegetable oils, including peanut, sunflower, rapeseed and soybean oil, economically viable but also abundantly available in contrast to the relatively premium olive oil recently discussed in the literature. 37 We have made an extensive comparison of the PQDs synthesised in the vegetable oils with the ones synthesised in mineral oil, a synthetic solvent commonly employed in this synthesis. The CsPbBr 3 colloids prepared in vegetable oils exhibit comparable photoluminescence (PL) spectra and crystalline structure to those obtained in mineral oil.…”

Testing for monotonicity, linearity and symmetry between trading volume and price returns in the futures markets of agricultural commodities: a discussion on the financial implications

“…the international prices of traditional staple foods reached their highest level in nearly 30 years (Chen et al, 2023;Panagiotou, 2015;Rapsomanikis and Mugera, 2011).…”

“…More specifically, between 2007 and 2008, agricultural commodity prices increased substantially, with the Food and Agricultural Organization food price index rising by 63% between January 2007 and June 2008, as compared with an annual increase rate of 9% in 2006 (Piot-Lepetit and M’Barek, 2011). During the same period, the international prices of traditional staple foods reached their highest level in nearly 30 years (Chen et al , 2023; Panagiotou, 2015; Rapsomanikis and Mugera, 2011).…”
