Abstract: | We conjecture that macro-level institutions affect equity tradingcosts through their impact on information risk and investorparticipation. In a study of trading costs for 412 NYSE-listedAmerican Depository Receipts (ADRs) from 44 countries, we findthat, after controlling for firm-level determinants of tradingcosts, effective spreads and price impact of trades are significantlylower for stocks from countries with better ratings for judicialefficiency, accounting standards, and political stability. Tradingcosts are significantly higher for stocks from French civillaw countries than from common law countries. Overall, we concludethat improvements in legal and political institutions will lowerthe cost of liquidity in financial markets. |
