Diversification in Trade and Foreign Investment and Resilience to the Covid ‐19 Shock
Using data from the COVID‐19 period, this study examines whether firms' participation in global value chains (GVCs) makes them more resilient to external negative shocks, distinguishing between multinational and nonmultinational firms and between trading and nontrading firms. Using Japanese customs data matched with firm‐level data and a survey on foreign direct investment (FDI), we construct a dataset that contains export destinations, import or…
Solitude, connection with society, low quality of life in relation to autism spectrum disorder
Background: Social communication and interaction deficits are characteristics of autism spectrum disorder (ASD). However, no study reported the association between living alone and quality of life (QOL) in participants with ASD. Aims: To evaluate the association among solitude, connection with society, low quality of life, and ASD. Methods: We conducted a web survey-based cross-sectional study of 3,865 Japanese participants with ASD living alone …

The Effect of Exporting on Creative Destruction and a Plant's Average Product Characteristics in Japan and Korea
This paper examines whether exporting activity contributes to the promotion of creative destruction and the upgrading of a plant's product portfolio. We first present evidence that exporters tend to produce, on average, products with higher attributes than non‐exporters. Next, we find evidence that exporting improves a plant's average product attributes, utilizing the propensity score difference‐in‐difference matching technique. Further examinati…
The Evolution of the Productivity Dispersion of Firms - A Reevaluation of Its Determinants in the Case of Japan
Why Do Some Firms Persistently Outperform Others? An Investigation of the Interactions between Innovation and Export Strategies
Global Fixed Capital Investment by Multinational Firms
We develop and test a model of the simultaneous determination of global gross fixed capital investments by multinational firms. We integrate a model of multi‐product firms choosing optimal manufacturing locations with a model of dynamic investment optimization. Firms adjust capital stocks in each location in accordance with the expected marginal profitability of capital. Analysis of 1504 fixed capital investment decisions by Japanese multinationa…
Why some firms persistently out-perform others
Although heterogeneity in the performance of firms is a well-established stylized fact, we still lack full understanding of its origins and the reasons why it persists. Instead of assuming that performance differences are exogenous, this article focuses on two endogenous strategies—innovation and global engagement—and interprets them as two ways to accumulate knowledge and improve firms’ capabilities. We are particularly interested in analyzing i…
