August 2017The Decline in Bank-Led Corporate Restructuring in Japan: 1981-2010
with Takeo Hoshi, Ulrike Schaede: w23715
Using a unique dataset on all major corporate restructuring events in Japan between 1981 and 2010, we examine how bank-led rescue operations in Japan have changed over time. The incidence of restructuring by distressed firms has become less frequent after the 1990s. When firms undergo restructuring, they adopt real adjustments in terms of labor, assets and finance, but the intensity of these adjustments has also declined over time. In line with existing research, we interpret these findings as strong indicators of changing corporate governance in Japan, in particular in terms of the decline in corporate monitoring functions of main banks.
March 2015Exchange Rate Exposure and Risk Management: The case of Japanese Exporting Firms
with Takatoshi Ito, Kiyotaka Sato, Junko Shimizu: w21040
This paper investigates the relationship between the Japanese firms’ exposure to the exchange rate risk and risk management, such as choice of invoicing currency, and financial and operational hedge. The firm’s exposure to the exchange rate risk is estimated by co-movements of the stock prices and exchange rates, following Dominguez (1998) and others. Data on risk management measures—financial and operational hedging, the choice of invoice currency and the price revision strategy (pass-through)—were collected from a questionnaire survey covering all Tokyo Stock Exchange listed firms in 2009. Results show the followings: First, firms with greater dependency on sales in foreign markets have greater foreign exchange exposure. Second, the higher the US dollar invoicing share, the greater is th...

July 2010Why has the yen failed to become a dominant invoicing currency in Asia? A firm-level analysis of Japanese Exporters' invoicing behavior
with Takatoshi Ito, Kiyotaka Sato, Junko Shimizu: w16231
It has been a well-known puzzle why the yen has not been used more in trade invoicing among Japanese exporters. Despite the yen's status as an only fully convertible currency in Asia, two patterns stand out as puzzling features of an excessively small share of yen invoicing: First, a strong tendency of Japanese exporters to choose importer's currency in their exports to advanced countries, and second, the prevalence of US dollar invoicing in Japanese exports to East Asia even though Japanese firms have built a regional production network in the last two decades. New possible determinants of currency invoicing at a firm-level are found through interviews with Japanese representative exporting firms. Invoicing behavior is examined by probit estimation using the unique data set on the firms' ...
