Too Small To Protect? The Role of Firm Size in Trade Agreements

This paper develops a new model of a trade agreement that puts at center stage the competing interests between firms within a sector. Larger firms favor trade liberalization whereas smaller firms favor protection. Lobbying by firms for or against the agreement is modelled as an all-pay auction, thus incorporating the feature that binding contracts over contributions for policies cannot be written. A new motive for trade agreement formation is uncovered in this framework whereby governments’ incentives to liberalize are driven by the lobbying process. If a proposed agreement is over non-tariff barriers then it always entails free trade. If a proposed agreement is over tariffs then it either entails free trade, which maximizes lobbying revenue, or the tariff revenue maximizing tariff. This outcome is supported by the surprising result that, off the equilibrium path, any tariff agreement that entails lobbying and positive tariffs yields lower expected revenue for the government than a free trade agreement involving no tariff revenue.
