Financial intermediation and structural change
研究了金融发展（如银行分支去监管）是否强化了后工业化阶段经济从制造业向服务业的结构变迁，通过理论和美国数据证实了去监管会加速服务业占比上升。
Abstract Does financial intermediation affect structural change? We address this question both theoretically and empirically, focusing on whether financial development reinforces structural change during the post‐industrialization phase, where employment, value‐added, and expenditure shares change towards services and away from manufacturing. We build a dynamic general equilibrium model in which structural change may be driven by mutually independent engines – sectoral productivity gaps, asymmetric factor elasticities – as well as by learning‐by‐doing. In all its variants, the model robustly predicts that exogenous reductions in intermediation costs (e.g., deregulation shocks) reinforce structural change. We take this prediction to the data by examining the effects of bank branching deregulation in the United States in the period from the 1960s to the 1990s. Within a staggered difference‐in‐differences framework, we show that bank branching deregulation reinforces the pattern of structural change already underway, leading to an increase in the services share of output and employment in deregulated states.
