• APO Productivity Databook 2025

  Koji Nomura and Mun S. Ho, Asian Productivity Organization, Keio University Press, 2025.09,  Page： 219

  　View Summary

  The 18th edition of the APO Productivity Databook provides standardized productivity and growth comparisons across 33 Asian economies and several global reference countries. Spanning more than five decades (1970–2023), it evaluates Asia’s structural transformation, post-COVID-19 recovery, and projections through 2035. Productivity enhancement is emphasized as the foundation of sustainable long-term growth, either by increasing output with given inputs or by maintaining output while reducing resource use. Enhancing national productivity metrics remains a fundamental policy imperative. To support this goal, the Databook systematically evaluates historical performance and prospects based on harmonized data and robust methodologies.
  It establishes baseline indicators of economic growth and productivity across 33 Asian economies, including the 21 APO members and 12 non-member Asian countries. The APO21 consists of Bangladesh, Cambodia, the Republic of China (ROC), Fiji, Hong Kong, India, Indonesia, the Islamic Republic of Iran (Iran), Japan, the Republic of Korea (Korea), the Lao People’s Democratic Republic (Lao PDR), Malaysia, Mongolia, Nepal, Pakistan, the Philippines, Singapore, Sri Lanka, Thailand, Turkiye, and Vietnam. The twelve non-member economies in Asia are Afghanistan, the Kingdom of Bhutan (Bhutan), Brunei Darussalam (Brunei), the People’s Republic of China (China), the Maldives, Myanmar, and the Gulf Cooperation Council (GCC), consisting of Bahrain, Kuwait, Oman, Qatar, Saudi Arabia, and the United Arab Emirates (UAE). Afghanistan and the Maldives are being incorporated for the first time in the 2025 edition. In addition, Australia, the European Union (EU), France, Italy, Germany, New Zealand, the United Kingdom (UK), and the United States (US) are included as reference economies.

• Hydropower-Led Economic Growth in Bhutan: Development of Industry-Level Productivity Account, 1990–2022

  Koji Nomura, Contemporary South Asian Studies, Springer, 2025.05,  Page： 259

  　View Summary

  This book provides a comprehensive analysis of Bhutan’s economic growth and productivity dynamics from 1990 to 2022, with a special focus on hydropower development. Through the construction of detailed industry-level productivity accounts, the study addresses significant data gaps in Bhutan’s national accounts, measuring outputs and inputs across various sectors and developing quality-adjusted labor and capital input series. The analysis reveals the complexities of Bhutan’s hydropower-led growth strategy: while the sector has driven substantial economic growth, its contribution to overall productivity improvement has been limited. The electricity sector shows gains in labor productivity but declining capital productivity, resulting in stagnant Total Factor Productivity (TFP). The study also examines productivity trends in non-electricity sectors and addresses potential “Dutch disease” effects on manufacturing and agricultural competitiveness. International comparisons place Bhutan’s productivity performance in a regional context, revealing significant gaps in productivity performance, particularly when compared to India, Bhutan’s largest trading partner and a regional economic benchmark. This comparative analysis informs policy recommendations for achieving more balanced and sustainable economic growth. The findings are particularly relevant for Bhutan’s Thirteenth Five-Year Plan (2024–2029), which emphasizes productivity improvements across all economic sectors. The book serves as a valuable resource for policymakers, economists, and researchers interested in development economics, particularly those focused on the unique challenges faced by small, landlocked nations pursuing sustainable economic development.

• Energy Productivity and Economic Growth: Experiences of the Japanese Industries, 1955–2019

  Koji Nomura, Springer, 2023.01,  Page： 268

  　View Summary

  Energy costs in the economy amount to only a few percent of gross domestic product, but their importance to economic growth is much greater than their apparent number. Energy is used in almost all production and consumption activities, and energy price changes induce significant spillover effects throughout the economic system. More importantly, stable and affordable access to energy is a critical factor in determining the rate of capital accumulation in a domestic economy and, hence, labor productivity growth. The expansion of production per hour worked is achieved by using more and higher quality capital, which requires more energy to operate. This book aims to provide robust observational facts on energy productivity improvement (EPI) and to analyze the mechanisms of EPI achieved in Japan’s economic growth from 1955 to 2019. Linking the productivity account with energy statistics enables us to attempt not only to develop a better indicator of energy productivity but also to evaluate the EPI with other significant changes in the production process, such as capital productivity, labor productivity, and even the overall efficiency measured in terms of total factor productivity. This book is a valuable resource for researchers and policymakers seeking to understand the role of energy throughout the economy and for economic planners seeking to ensure the efficient use of energy now and into the future.

• "How Does the Social Implementation of Technological Innovation Transform the Japanese Economy?—Visualizing Structural Change with the High-Resolution Economic Model BIP" (in Japanese)

  Koji Nomura

  SBI Research Review (SBI Financial and Economic Research Institute)  9   27 - 49 2026.02

  Research paper (bulletin of university, research institution), Single Work

  　View Summary

  本稿は、技術革新の社会実装が日本経済に及ぼす影響を評価する高解像度経済モデルBIPを構築する。BIPは、技術革新がどの経済活動にいかなる構造変化を通じて波及するのかを可視化し、生産・就業・分配・エネルギー消費といった多面的な経済特性を一般均衡の枠組みの下で整合的に捉えることを目的とする。停滞する日本経済の延長線上にあるBaUシナリオと技術革新の社会実装が進展するTSIシナリオが試算され、2040年における分岐像を描写する。TSIでは、サービス部門の拡大が進む一方、その成長メカニズムの中核には製造業を基軸とした産業基盤の再構築があることが示される。BaUから257兆円の名目付加価値拡大が生じ、うち132兆円はAI活用による生産性改善や市場拡大に起因する。こうした生産性向上は、労働時間の短縮と賃金上昇を同時に実現しつつ、電力の安価かつ安定的な供給を背景として国内の資本蓄積を促進し、日本経済の成長経路を大きく変えることを示している。

• "Measuring Real Energy Price Gaps: The Real PLI Framework for Competitiveness Monitoring"

  Koji Nomura and Sho Inaba

  Sustainability 18 ( 1 )  2026.01

  Research paper (scientific journal), Joint Work, Corresponding author, Accepted

  　View Summary

  Global energy markets have experienced persistent dispersion in real energy prices, creating structural competitiveness pressures that standard indicators often fail to capture in real time. These pressures have intensified as energy-intensive sectors face asymmetric exposure across advanced and emerging economies. This study addresses two critical gaps in international energy cost competitiveness. The first is a frequency gap: conventional indicators such as the Real Unit Energy Cost (RUEC) are typically published with delays of 2–5 years, limiting their usefulness for timely policy evalua-tion. Here, both RUEC and the Real Price Level Index for energy (Real PLI)—the ratio of the Purchasing Power Parity (PPP) for energy to that for GDP—are measured with only a 2–3-month lag for nine countries—four in Asia, four in Europe, and the U.S. The second is a competitiveness gap that calls for policy responses. Real PLIs indicate that the energy price disadvantages of Japan, Korea, France, Germany, Italy, and the UK have widened from 1.76–2.91 times the U.S. level before the pandemic to 2.14–3.28 times by Q3 2025, with the gaps relative to China and India also widening. Once coun-try-specific thresholds are exceeded, output in energy-intensive and trade-exposed (EITE) industries tends to contract disproportionately. These findings highlight that sustainable transitions require not only internationally differentiated burden-sharing but also structural reforms to avoid persistent widening of energy price gaps. The Real PLI framework provides a timely indicator of competitiveness and an early-warning tool, signaling when growing asymmetries may undermine policy feasibility. Policy implications include the need to monitor real energy price dispersion as a core source of competitiveness risk, to strengthen structural measures that stabilize marginal en-ergy costs, and to design transition pathways that account for heterogeneous adjust-ment pressures across countries.

• "Productivity Dynamics in the Maldives: A First Outlook Based on the Maldivian Productivity Accounts, 1970–2023, with Comparisons to SAARC and Fiji"

  Koji Nomura

  (United Nations Economic and Social Commission for Asia and the Pacific)   2025.10

  Research paper (other academic), Single Work

  　View Summary

  This report presents the first comprehensive productivity analysis for the Maldives based on the newly developed Maldivian Productivity Accounts, covering the period 1970–2023 and including cross-country comparisons with SAARC members and Fiji. The results show that sustained economic growth of 5–7% per year from 1970 to 2019 was supported by a nearly thirtyfold expansion of capital input and a twentyfold increase in labor input, including migrant workers. However, improvements in TFP have remained close to zero or even negative. The capital–output ratio reached 5.3 in 2023—the highest in the SAARC region—reflecting low investment efficiency and possible overaccumulation. Transitioning from quantity-driven to efficiency-based growth is essential for the Maldives to achieve sustainable productivity and long-term economic resilience.

• "Bhutan’s Productivity Trends, 1990–2023: Findings from Bhutanese Productivity Account 2025"

  Koji Nomura

  (United Nations Economic and Social Commission for Asia and the Pacific)   2025.08

  Research paper (other academic), Single Work

  　View Summary

  The Bhutanese Productivity Account 2025 provides updated productivity estimates for 1990–2023, developed jointly by the DMDF and Keio University. While Bhutan’s hydropower-led growth model has achieved rapid labor productivity gains, the report reveals persistent stagnation in total factor productivity (TFP) and a steep decline in capital productivity. Capital input accounted for nearly 84% of GDP growth during this period, yet TFP contributed negatively on average, underscoring a pattern of capital accumulation without corresponding efficiency gains. The electricity sector, despite significant investment, saw long-term declines in TFP due to rising construction costs and limited output growth. Moreover, positive spillover effects to non-electricity industries have been limited, with manufacturing showing only modest improvements. International comparisons highlight a widening TFP growth gap between Bhutan and countries like India. Growing electricity demand from data centers and rising import dependency pose further challenges. The report emphasizes that Bhutan’s growth cannot be fully understood through labor productivity alone. To achieve sustainable, high-quality growth aligned with the 13th Five Year Plan, Bhutan must improve productivity in non-electricity sectors through investment in innovation, human capital, and structural reform, while addressing electricity supply constraints and maintaining macroeconomic resilience.
