This book provides a comprehensive analysis of Bhutan 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 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 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 productivity performance in a regional context, revealing significant gaps in productivity performance, particularly when compared to India, Bhutan 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 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.
