Benchmarking Dynamically Stable Public Debt Trajectories for Low-Income Countries

In this paper, we develop two complementary approaches for benchmarking the public debt trajectories of Low-Income Countries (LICs) to assess their dynamic stability. We compare the evolution of the overall public debt-to-GDP ratios of reference LICs with the historical experiences of other countries with similar characteristics, which are now further down the path of economic development and have not experienced public debt stress events. We rely on both direct comparison and a novel application of the synthetic control method (SCM). These public debt trajectories that are dynamically stable from a historical perspective can provide insights into debt sustainability analyses for LICs.
