The geographic extent of global supply chains: evidence from Southeast Asia

We study the extent to which inter‐firm relationships are locally concentrated and what determines firm differences in geographic proximity to domestic or foreign suppliers and customers. From micro‐data on self‐reported customer and supplier data of firms in Indonesia, the Philippines, Thailand, and Vietnam, we measure the distances between firm pairs, that is, the distance to the main supplier and the distance to the main customer for the surveyed firms. The distances to suppliers and customers are shorter for indigenous firms in these Southeast Asian countries; but the arm's length differs across countries. The distance between firm pairs differs widely across firms within narrowly defined industries and countries. We find that both firm‐level transaction costs and capabilities affect the distances between customers and suppliers. The distance to suppliers is longer for firms that have accepted guest engineers from the main supplier to maintain production processes. Further, we find that the distances to suppliers and customers are longer for firms that have undertaken organisational change or improved marketing practices.     

Hypothetical extractions from a global perspective

ABSTRACT

The hypothetical extraction method (HEM) has been widely used to measure interindustry linkages and the importance of industries. HEM considers the hypothetical situation in which a certain industry is no longer operational. HEM was developed for national economies, using national input–output tables. When performing HEM, it is assumed (often implicitly) that the input requirements that were originally provided by the extracted industry are met by additional imports in the post-extraction situation. Applying HEM to global multiregional input–output tables then causes serious problems. It is no longer sufficient to assume that the required inputs are imported. Instead, it is necessary to indicate explicitly how much is imported from each origin to replace the original inputs. Our adaptation of HEM is the global extraction method (GEM). As an illustration, GEM is applied to the extraction of the motor vehicle industry in China, the US, and Germany, using the 2014 WIOD input–output table.     

Typical lots for detached houses in residential blocks and lot shape analysis

The notion of shape distance between lots is the basis for further development of the economics of dealing with lot shapes in real estate. The distance between two lots is defined as the relative area of the set difference of two lots. Using this notion, a method for identifying typical lots in a residential block based on the shape distance matrix among all the lots in the block is proposed. The method is applied to 20 blocks in the Setagaya ward in Tokyo. Typical lots tend to be rectangular-type lots even in irregularly shaped blocks. This suggests that consumers prefer rectangular shapes when choosing residential lots. Moreover, rectangular blocks tend to contain typical rectangular lots that have a depth about half as long as the shorter edge of the block and two variations of width. This suggests that some lots were previously subdivided in half.     

Vertical trade and free trade agreements

We investigate the effects of free trade agreements (FTAs) on tariffs and welfare in vertical trade. We consider a three-country model, where an FTA is formed between a country exporting a final good and a country exporting an intermediate good. The FTA unambiguously leads to a reduction in the member country’s tariff, but may cause the non-member country’s tariff level to increase. In the case, where FTA raises the non-member country’s tariff level, the FTA increases that country’s welfare. In contrast, the FTA may render its member countries better off. This result implies that the formation of an FTA may not always be Pareto-improving.     

Do Borders Matter? Evidence from Japanese Regional Net Capital Flows

Are international borders barriers to capital flows? We use evidence on net capital flows among regions within a country as a benchmark. For this purpose we develop a data set of saving and investment rates of Japanese prefectures. We find that the correlation between saving and investment rates is higher for OECD countries than for Japanese regions in both time‐series and cross‐sectional data. After controlling for factors that are expected to contribute to a positive correlation in the absence of barriers to capital flows, we conclude that primarily long‐term capital flows are hindered by national borders, as reflected in the cross‐sectional evidence.     

Productivity versus elasticity: a normalized constant elasticity of substitution production function applied to historical Soviet data

This study tests the extensive growth hypothesis, which would attribute the Soviet economic slowdown to low elasticity of substitution and over-investment rather than deteriorating productivity growth. To circumvent the low availability of data, widely applicable new methods for estimating productivity and elasticity of substitution were developed based on the normalized constant elasticity of substitution (CES) production function. One is an extended version of the Solow residual calculation, and the other is a direct estimation of the time-varying parameter normalized CES production function. The application of the methods to the Soviet data showed a decreasing trend in productivity growth and a low elasticity of substitution of approximately 0.25. The results neither reject nor support the extensive growth hypothesis because of uncertainty in the interpretation of the low elasticity of substitution. The results suggest that it is reasonable to assert that both deteriorating productivity growth and low elasticity of substitution caused the Soviet economic slowdown. Further empirical studies on productivity and elasticity of substitution in the Soviet and other economies are necessary to fully understand relations between productivity growth, elasticity of substitution and economic development.     

The effects of cross-regional free trade agreements under a vertical industry structure

This paper examines the effects of a cross-regional free trade agreement (FTA) on tariffs, welfare, and the incentives for multilateral free trade in a three-country model with a vertical industry structure. We show that the FTA induces member countries to reduce their tariffs on nonmember countries. On the other hand, a nonmember country lowers its tariff on final-good imports, but raises its tariff on intermediate-good imports. Also, the FTA makes member and nonmember countries better off. After the FTA is enacted, member and nonmember countries have an incentive to support multilateral free trade, so an FTA acts as a building block for multilateral trade liberalization.     

The relationship between supervisor and workers — The case of professional baseball in Japan

This paper analyzes the relationship between the workers' productivity and the supervisor from the point of view of the Matching Hypothesis using data from professional baseball in Japan. The main findings of this paper are the following three points. The first point is that the Matching Hypothesis is rejected in the case of pitchers and hitters. The second one is that the depreciation rate of the effect is about 10–15% per year and differs from zero significantly. Hence, the effect continues for a long time after the matching is broken. Lastly, we cannot find a learning curve for the managers' ability.
