We propose entertainment and travel costs (ETC) expenditures as a measure of corruption in Chinese firms. These expenses are publicly reported in firms' accounting books, and on average they amount to about 3 percent of a firm's total value added. We find that ETC is a mix that includes grease money to obtain better government services, protection money to lower tax rates, managerial excesses, and normal business expenditures to build relational capital with suppliers and clients. Entertainment and travel costs overall have a significantly negative effect on firm productivity, but we also find that some components of ETC have substantial positive returns to firms.
