Financial Liberalization, Debt Mismatch, Allocative Efficiency, and Growth
研究金融自由化如何通过允许债务期限错配放松信贷约束，但内生地引发危机风险；发现受监管的自由化能提升配置效率与增长，而无约束的自由化则导致效率下降。
Financial liberalization increases growth, but leads to more crises and costly bailouts. We present a two-sector model in which liberalization, by allowing debt-denomination mismatch, relaxes borrowing limits in the financially constrained sector, but endogenously generates crisis risk. When regulation restricts external financing to standard debt, liberalization preserves financial discipline and may increase allocative efficiency, growth, and consumption possibilities. By contrast, under unfettered liberalization that also allows uncollateralized option-like liabilities, discipline breaks down, and efficiency falls. The model yields a testable gains-from-liberalization condition, which holds in emerging markets. It also helps rationalize the contrasting experience of emerging markets and the recent US housing crisis.
