RIETIとCEPR（Centre for Economic Policy Research）は、研究交流の一環として、本テーマに関する理解を深め、研究の深化を図るため、ロンドンにおいて以下のjoint workshopを開催しました。
"Regionalization vs. Globalization"
Both global and regional economic linkages have strengthened substantially over the past quarter century. We employ a dynamic factor model to analyze the implications of these changes for the evolution of global and regional business cycles. Our model allows us to assess the roles played by the global, regional, and country specific factors in explaining business cycles in a large sample of countries and regions over the period 1960-2010. We find that, since the mid-1980s, the importance of regional factors has increased markedly in explaining business cycles, especially in regions that witnessed a sharp growth in intra-regional trade and financial flows. By contrast, the relative importance of the global factor has declined over the same period. In short, the recent era of globalization has witnessed the emergence of regional cycles.
"Determinants of Currency Invoicing in Japanese Exports: A firm-level analysis"
Currency invoicing in Japanese exports has two puzzling patterns concerning an excessively small share of yen invoicing: one is a strong tendency of Japanese firms to choose the importer's currency invoicing in exports to developed countries and the other is the prevalence of U.S. dollar invoicing in Japanese exports to East Asia even though Japanese firms have built a regional production network over two decades. To address the puzzles, we propose new possible determinants of currency invoicing at the firm-level, based on an interview analysis with Japanese representative exporting firms, and then empirically test them by probit estimation using the unique dataset on the firms' currency invoicing choice by destination. Our novel findings suggest that a surprisingly low share of yen invoicing in Japanese exports even in the 2000s is attributed not only to the growing intra-firm trade through the active overseas operations of Japanese firms but also to the unique production/trade structure in Asia mainly established by Japanese electronics companies.
"Industry-Specific Effective Exchange Rates for Japan: Does the nominal yen appreciation matter for Japanese exporters?"
It has been argued that nominal appreciation of the yen vis-à-vis the U.S. dollar deteriorates the export price competitiveness of Japanese exporters. When the collapse of Lehman Brothers occurred in September 2008, for instance, the bilateral nominal exchange rate of the yen appreciated sharply vis-à-vis all currencies, which resulted in a large decline in Japanese exports. The yen has continued appreciating since then, staying around 76-79 yen vis-à-vis the U.S. dollar. A natural question is whether such appreciation in bilateral nominal terms has deteriorated the export competitiveness of Japanese export firms and whether the nominal yen appreciation has different effects across industries in Japan. It is well known that an effective exchange rate (EER), not bilateral nominal exchange rates, is a better measurement for considering the export firms' competitiveness in the global market. While both nominal and real EERs (REER) are now published by the Bank for International Settlements (BIS) and central banks, they are constructed by aggregate based trade weights. The industry-specific EERs are far more useful for considering the empirical importance of the exchange rate on producer profits in specific industries, though such industry-specific EERs are seldom available. The novelty of this study is to construct a new data set of the industry-specific EERs of the yen in both nominal and real terms on a daily basis from 2005 to the present to provide a better indicator for the international price competitiveness of Japanese exporters. By conducting simulation analysis, we examine whether recent fluctuations of the REER of the yen have been driven by domestic or foreign price changes. We also conduct a structural value at risk (VAR) analysis to investigate whether Japanese exports at the industry level are significantly affected by REER fluctuations, and which economic shocks most affect Japanese exports.
