This paper surveys the theory on zombie lending incentives and the consequences of zombie lending for the real economy. It also offers a historical perspective by reviewing the growing empirical evidence on zombie lending along three dimensions: (i) the role of under-capitalized banks, (ii) effects on zombie firms, and (iii) spillovers and distortions for non-zombie firms. We then provide an overview of how zombie lending can be attenuated. Finally, we use a sample of U.S. publicly listed firms to compare various measures proposed in the literature to classify firms as ``zombies." We identify definitions of zombie firms that are adequate to investigate real sector competitive distortions of zombie lending. We find that only definitions that are based on interest rate subsidies are able to detect these spillovers.
