Firm size‐specific trade effects of regional trade agreements: Estimating extensive and intensive margins of trade

AbstractWe estimate the impacts of Korean firms’ participation in regional trade agreements (RTAs) on the extensive and intensive export margins by identifying exporting firms based on their firm size—small and medium‐sized enterprises (SMEs) and large enterprises (LEs) at the 5 399 HS six‐digit commodity level—and specifying characteristics of RTAs from 2004 to 2015. We apply the EK Tobit estimation technique to control zero trade and the OLS estimation with importer‐product and time fixed effects to alleviate the endogeneity problem. We find that firm size, product type, and depth of RTA significantly matter. Specifically, we find that deeper RTAs with larger, developing, and closer members significantly enhance the export creation effects of SMEs and LEs. Regarding the firm size‐specific effects, we find that SMEs are less sensitive to exploiting RTA participation but more sensitive to the import market size, bilateral and relative trade costs, and the RTA characteristics. LEs’ export creation is mainly driven by the intensive margin, while SMEs’ export creation is driven by extensive and intensive margins (slightly more by the extensive margin). For the product‐specific effects, we find that Korea's major exportable products such as chemicals, basic metals, motor vehicles, and transport equipment generate significantly strong export creation effects for both LEs and SMEs through their participation in RTAs.

Accounting for trade deficits

This paper proposes a decomposition for the total trade deficit of a country by using implications of a dynamic trade model. It is shown that the total trade deficit of a country can be decomposed into changes due to its effective terms of trade, its relative trade costs, and its macroeconomic developments with respect to its export partners. The implications for bilateral trade are estimated using both imports and exports data for 188 countries, and the decomposition of total trade deficit is achieved for each country. Empirical results show evidence for heterogeneity across countries regarding the decomposition of trade deficits, suggesting alternative policy tools to rebalance trade at the country level. A cross-country investigation further suggests that relative trade costs, followed by relative macroeconomic developments, have contributed the most to the heterogeneity of trade imbalances.

Institutional Quality, Trade Costs and Comparative Advantage

Earlier works derive empirical implications that institutional quality is very influential as a source of comparative advantage in industries requiring relationship-specific investment from the supplier. However, as earlier studies focus on investigating the impact of institution on the efficiency of the producer, only the exporter’s institution is considered. In contrast, we attempt to identify the impacts of the quality of institution, of both exporters and importers, on trade costs, that are different across country-pairs. To check the problem of measuring trade costs, we use two alternative measures of trade costs, i.e. CIF/FOB ratio and the relative measure of trade costs proposed by Novy (2013). Using the Eora global supply chain database covering 187 countries for 11 primary and manufacturing industries and four years, 2000, 2005, 2010 and 2015, we calculate a CIF/FOB ratio and the relative trade costs suggested by Novy (2013) which are used as a proxy variable for trade costs. At the country level, we find that the institutional quality of exporter and importer is negatively associated with trade costs and trade costs increase as disparity between two countries’ institutional quality increases. At the country-industry level, we find that a country-pair with better legal institution has lower trade costs in industries for which a hold-up problem is important. This result is robust to the alternative measure of trade costs suggested by Novy(2013). However, an analysis on the impact of institutional differences on trade costs yields mixed results. Therefore we do not conclude that the similarity of institutional quality between two countries is associated with lower bilateral trade costs.

Industrial configuration in an economy with low transportation costs

We examine how the spatial economy with multiple industries is shaped when interregional trade costs and intraregional commuting costs are low. All industries are characterized by increasing returns to scale and monopolistic competition, and they are differentiated by their trade costs and the degree of intra-industry competition measured by their firm numbers. We find some distinct rules in industrial location. First, at most, one industry disperses, while others agglomerate in a region according to their ratios of relative trade costs to firm numbers. Second, industries with stronger competition constitute a smaller region, while those with higher trade costs compose a larger region. The results are consistent with the classical Weberian location theory and suggest that the degree of intra-industry competition also becomes an essential factor to determine industrial location when transportation costs are small. Finally, the population differential between the regions monotonically decreases in the relative commuting cost.

Is there an International Trade-Venue Clientele Effect for Canadian Shares Cross-Listed in the United States?

This paper extends the work by Amihud and Mendelson (1986) and Atkins and Dyl (1997a) that in equilibrium assets with higher spreads are held in portfolios with the same or expected longer holding periods. The paper examines whether or not investors have the same holding periods for the Canadian cross-listed share trades executed in the U.S. trade venues relative to the same-firm share trades executed in the TSE, and whether or not any differences are associated with the size of their relative effective half-spreads. The results support the trade-venue clientele hypothesis for the Canadian cross-listed shares whose trades are executed in the TSE and the AMEX, the TSE and NASDAQ, and the TSE and NYSE, primarily for the period after the TSE decimalization on April 15, 1996. Holding periods (effective half-spreads) for share trades executed in the U.S. trade venues significantly decreased over time relative to investor holding periods (effective spreads) for the same-firm share trades executed in the TSE. This suggests that the TSE has consistently lost its share of executed order flow (share turnover) relative to the U.S. primary trade venues, and that this loss is associated with increased relative trade costs in the TSE.

The Home Market, Trade, and Industrial Structure

Does national market size matter for industrial structure? This has been suggested by theoretical work on marketeffects, as in Krugman (1980, 1995). In this paper, I show that what previously was regarded as an assumption of convenience—transport costs only for the differentiated goods—matters a great deal. In a focal case in which differentiated and homogeneous goods have identical transport costs, the home market effect disappears. The paper discusses available evidence on the relative trade costs for differentiated and homogeneous goods. No compelling argument is found that market size will matter for industrial structure.
