Abstract:Agricultural production is spread all over Turkey and the considerably different climatic and topographical conditions among the provinces lead to highly diversified agricultural production. Therefore, is it reasonable to assume an integrated market all over Turkey? The authors analyze spatial price transmission among 28 Turkish provinces with regard to wheat markets. They apply a bivariate threshold vector error correction model with two symmetric thresholds to account for transaction costs. They find an inne… Show more
“…However, it is worth stressing that such a restriction is satisfied only when two conditions are jointly satisfied: 1) both the upper and lower regimes contain observations; 2) coefficients estimated for the two outer regimes are not statistically different. Moreover, this restriction implies that a similar process drives prices 6 When ∆ܲ exceeds the band edge, e.g. the export price (ܲ ௧ ) falls and prices spread moves into lower regime, there are only two ways for price spread to be reduced and return to be lower than the band width: 1) the deviating price (ܲ ௧ ) raises and price spreads return within the band; 2) import price (ܲ ௧ ) falls accordingly, such that prices spread return within the band.…”

“…the farther the deviation from the band edge, the stronger the adjustment 6 . Balke and Fomby (1997) showed that, despite a possible local random walk inside the band, the process is globally stationary.…”

“…After testing for co-integration, the residuals show the deviation from equilibrium and this equilibrium error in the long-run tends to zero. Vector errorcorrection model (VECM) can be used to capture the deviations from the long-run equilibrium (Brosig et al, 2011). The model is represented as:…”

Spiraling prices of onions in India undermine the sustainability of current economic growth process and raised the question of price integration among the spatially separated markets. Co-integration test has been used to identify whether onion markets in India share a common linear deterministic trend and the law of one price holds true in view of rising prices in the recent past. The study sourced the wholesale daily prices of major onion markets across the country from January 2010 to March 2011. Augmented Dickey Fuller test statistic has been used to check the presence of a unit root in the time series data. Empirical results indicated the presence of unit root and a strong spatial integration between major markets. The study also confirms the law of one price in Indian onions.
“…Brosig et al (2011) argue that price adjustments can occur when traders readjust their price as a function of the other observed prices to avoid new entrants from arriving on the market. The study of Stephens et al (2012) shows that tomato prices in Zimbabwe adjust to their long term relationship even when there is no trade.…”

“…This facilitates the fixation of their transaction price. Following the assumptions of Pendell and Schroeder (2006), Brosig et al (2011), Ejrnaes and Persson (2010) and Stephens et al (2012), we guess that the information flow have a non-negligible role in the spatial price transmission. This is mainly supported by the fact that on agricultural commodity markets economic agents refer to a reference price to fix the price for their delocalized transaction.…”
