The World Bank, under the stewardship of the United States, stands out as the global leader among international development organizations. Does China's establishment of the Asian Infrastructure Investment Bank (AIIB) undermine this status? Examining this question, we focus on the borrowing practices of a special set of countries: the founding members of the AIIB. These founders openly defied the public preference of the United States, arguably to create a potential rival to the World Bank. Using a new causal inference method, Pang, Liu, and Xu's Dynamic Multilevel Latent Factor Model—as well as several well-known estimation models as robustness checks—we document at least a temporary decrease in the number of World Bank infrastructure projects that the developing AIIB founders have entered into. This study presents the first systematic evidence that China's AIIB could unsettle the political influence the United States has enjoyed over developing countries through its leadership of the World Bank. An important set of countries may be parting ways with the World Bank and looking to a Chinese institution for leadership in the world of development.
