The analysis of price transmission in transition countries is complicated by their often unstable policy environments. We utilise a Markov-switching vector error correction model (MSVECM) to allow for multiple regime shifts in the price relationship between wheat and wheat flour in Ukraine from...

Since the work of FEENSTRA (2002), the standard ANDERSON & VAN WINCOOP (2003) Gravity Model has been estimated using a fixed effects approach. However, a fixed effects approach has a major drawback: it does not allow for the estimation of exporter- and importer-invariant variables. Thus,...
