The demise of socialism in Eastern Europe and the transition to a market economy in China and India marked the end of traditional comparative economics as a field. The debate between capitalism and socialism was settled. The economic calculation argument of Ludwig von Mises seemed no longer relevant. In its place, the new comparative economics (NCE) arose.The NCE focuses on the institutional differences that affect the protection of contract and property rights. The research program of Andrei Shleifer has provided numerous insights into how markets operate. This paper examines the Shleifer-inspired program in comparative economics in light of the economic calculation argument Mises made. Although the recent developments in comparative economics have extended and complemented the contributions of Mises, it has not displaced them. An account of the economic calculation problem is still missing in the new comparative economics.
