Simple measures of endogenous free-riding in protectionist lobbies

Even though there is a well-known empirical and theoretical link between lobby and the free-rider problem, the existing literature only attributes its findings to the free-rider rather than the measurement of its extent. We develop broader theoretical micro-foundations for measuring free-riding and investigate the determinants of tariff rates from the perspective of corporate lobbying and free-riding. Our estimation result shows that the degree of free-riding not only varies across industries but is particularly high in larger industries indicating the underutilization of lobbying. The tariff rates under monopoly are about 8 times higher than under perfect competition in most industries suggesting that stakeholders should maintain higher industry protection levels through lobbying.
