The Value Of Face : Search And Contracting Problems Of Nigerian Trade

Better Essays

Summary: The paper titled “The value of face-to-face: Search and contracting problems in Nigerian trade” provides micro-empirical evidence of significant trade costs or costs of transactions over a distance within country associated with imperfect contract enforcement and inability to observe the frontier verities of products available in the source country or destination. Conventional gravity models of trade attempts to capture the costs associated with information friction by introducing proxies such as shared language or quality of legal institutions, however firm level effects of such information friction are largely absent in those models. To entangle the effects of informational frictions, the author identifies the two sources of …show more content…

The author estimates the parameters of the proposed model in two stages: in first stage parameters that are directly observable from the data are estimated and in second stage remaining parameters are estimated using simulated method of moments. From the estimated results the author finds that the traders who order instead of traveling pay approximately 15 percent cost premium and on an average 2.5 months behind the frontier of verities. The author also estimates the welfare effects of these frictions and finds that the welfare in the consumer goods sector increase by approximately 29 percent when there will be no search and contracting friction. In addition, the author performs some counterfactual analyses and shows that the welfare gain from eliminating search and contracting friction is smaller for a relatively developed country, welfare gains is higher at lower costs and barriers to travel, and potential demand for financial intermediation indicating the significant of incomplete contracting.
Comments: The paper is well-written and well argued. However, I think some issues require more discussion and justification and some assumptions need to be modified to make the paper more convincing. My comments are as follows (they appear in the same order as in the paper):
1. In section 3, the
