Transport costs, distance, and time : evidence from the Japanese Census of Logistics

Geographic distance is a standard proxy for transport costs under the simple assumption that freight fees increase monotonically over space. Using the Japanese Census of Logistics, this paper examines the extent to which transport distance and time affect freight costs across shipping modes, commodity groups, and prefecture pairs. The results show substantial heterogeneity in transport costs and time across shipping modes. Consistent with an iceberg formulation of transport costs, distance has a significantly positive effect on freight costs by air transportation. However, I find the puzzling results that business enterprises are likely to pay more for short-distance shipments by truck, ship, and railroad transportation. As a plausible explanation, I discuss aggregation bias arising from freight-specific premiums for timely, frequent, and small-batch shipments.

Investment promotion agencies: do they work?

In this paper, we examine the role of investment promotion agencies (IPAs) in promoting outward FDI from Japan and Korea. Looking at two home countries enables us to control for both country-pair time-invariant characteristics and host country time-varying characteristics. Our empirical results suggest that home-country IPAs tend to be more effective in promoting outward FDI in politically risky host countries. However, this finding depends on whether the home-country firm is listed or unlisted. More specifically, we find that the positive effect of home country IPAs on outward FDI in politically risky countries is limited to unlisted home- country firms, which are widely assumed to be less competitive and productive.

Do export promotion agencies increase exports?

In this paper, we examine the role of export promotion agencies (EPAs) in promoting exports from Japan and Korea. Looking at two home countries enables us to tackle endogeneity issues by controlling for both country-pair time-invariant characteristics and importing country time-varying characteristics. Our empirical results indicate that the coefficients of the EPA dummy are similar in size to those of the FTA dummy. This implies that establishing an EPA office in a country is equivalent to signing an FTA with that country. In addition, we find that EPA’s effects are larger for manufactured products than non-manufactured products. Finally, the EPA effect is larger for low income trade partners than for high income trade partners.
