The public and private sector costs of capital differ in the presence of taxes, because taxes are a cost to the private but not the public sector. We use a quasi-arbitrage approach to show how to include taxes in a comparison of capital costs. We find that taxes induce distortions that generate a systematic private sector preference for assets with rapid tax depreciation, high debt capacity, and low risk. We examine the implications of that preference for privatization, government outsourcing, and regulation. Our approach facilitates the analysis of transactions such as pure risk transfers, otherwise difficult using standard discounting methods.
