Executive leadership, policy tourism, and policy diffusion among local governments
研究了美国城市间政策旅游现象，发现拥有经验丰富但新上任的少数族裔领导的城市，更倾向于访问由经验丰富的白人或女性领导的城市，且政策旅游多发生在环境复杂、资源丰富且动荡的城市之间。
Abstract Policy tourism is an important but rarely studied phenomenon describing a widespread practice, through which local public and business leaders form delegations, choose target cities, and implement intercity policy diffusion, business exchange, and economic collaboration. Our research examines how executive leadership characteristics, city‐level contextual factors, and interdependence mechanisms relate to cities' decisions to visit. Using two‐stage probit selection models with instrumental variables on a dyadic balanced panel dataset recording all policy tourism events between major U.S. cities from 2007 to 2016, we answer this question accounting for potential endogeneity problems. Our findings suggest that cities with experienced yet newly appointed, minority leaders tend to visit cities with experienced white or female leaders. Additionally, policy tourism happens among cities embedded in highly complex, munificent, and turbulent environments. Finally, cities tend to learn from peers with higher economic prosperity or interact with their competitors.
