||A two-country, two-firm model has been developed to study equilibrium lobbying positions in intra-industry trade under cost uncertainty. A firm chooses either a protect ionist position or a free-t rader position. The model predicts that taking the free-trader (protectionist) lobbying position is an effi cient (inefficient) firm's dominant strategy. In addit ion, for any lobbying position taken by a firm, its lobbying effort always decreases as its production cost increases. The findings help shed light on some empirical observations.
