Organic certification systems and international trading of agricultural products in gravity models

摘要: Abstract Recent literature about gravity models points out the importance of institutional frictions in international market agricultural products beyond traditional economics variables as transport costs reducing mass trade bilateral relationships. In particular, previous contributions stress that harmonization food standards could decrease transaction trading relationships by stimulating market. a work we hypothesized acknowledgment equivalence organic may represent reliable signal affinity which be useful to identify areas for both conventional and are lower. This article represents step forward, since it assumes identifying with lower whole produce strong assumption relaxed through hypothesis exchange simply signaled presence involved countries. Therefore, our analysis test if countries setting specific rules more “affine” because low common cultural, law political distance but also differences themselves can differentiate level among regions. Interesting insights policy makers identification relevant business arise from an econometric analysis. JEL codes: Q11, Q 13 Keywords: Gravity models, standards, costs, market, trade, products.
