In this paper we survey the literature on asymmetric price transmission. This literature contains a substantial share of publications by agricultural economists. After classifying the different types of asymmetric price transmission in section 2, we describe the explanations for asymmetric price transmission that have been proposed in section 3. In section 4 we focus on the econometric techniques used to quantify asymmetry. Section 5 concludes with a discussion of outstanding methodological problems and suggestions for future research. Our main conclusion is that the existing literature is far from being unified or conclusive, and that a great deal of work remains to be done. A wide variety of often conflicting theories of and empirical tests for asymmetry co-exist in the literature. Furthermore, existing tests are not discerning in the sense that they as a rule to do not make it possible to choose between competing explanations for asymmetry on the basis of empirical results. Therefore, after more than three decades of work, a considerable need for further research remains, and it would appear premature to draw far reaching conclusions for theory and policy on the basis of work to date.
