Paths toward the modern fiscal state : England (1642-1752), Japan (1868-1895), and China (1850-1911)
This dissertation examines the rise of the modem fiscal state, which enabled the state to use centrally collected revenues from indirect taxes to mobilize financial resources either through long-term borrowing or issuing paper notes. The modem fiscal state greatly enhanced state capacity and …
