I decided to look at the issue from the perspective of Turkish export supply, and going through the literature, I found a useful CBT paper. While the objective of the paper is to analyze structural changes in Turkish exports, it estimates export supply and import demand for Turkey. I liked the paper because the data is relatively recent and because the estimated coefficients are time-varying, as the authors have adopted the Kalman filter approach.
While I would expect the intercept term to be larger and increasing through time (just a hunch), their results, with the export demand elasticity of OECD income at around 0.5, suggest that the export pullback because of a European recession will not be as great as suggested in some recent research reports. Trade data for August, which will be released on Friday, and September, will be a litmus test in this sense.
