The authors introduce a model of the retail firm in which consumers and active firms benefit collectively from coordination of sales at fewer firms. Using this model, the authors show that ostensibly uninformative advertising plays a key role in bringing about coordination economies by directing...

We provide a first formal analysis of the international rules that govern the use of subsidies to domestic production. Our analysis highlights the impact of the new subsidy disciplines that were added to GATT rules with the creation of the WTO. While GATT subsidy rules were typically viewed as...

The authors propose a unified theoretical framework within which to interpret and evaluate the foundational principles of GATT. Working within a general equilibrium trade model, they represent government preferences in a way that is consistent with national income maximization but also allows...

We characterize the design of an optimal trade agreement when governments are privately informed about the value of tariff revenue. We show that the problem of designing an optimal trade agreement in this setting can be represented as an optimal delegation problem when a money burning instrument...

According to the terms-of-trade theory, governments use trade agreements to escape from a terms-of-trade-driven prisoner's dilemma. We use the terms-of-trade theory to develop a relationship that predicts negotiated tariff levels on the basis of pre-negotiation data: tariffs, import volumes and...

A new welfare-enhancing role is identified for a policy of export subsidization in a new-product industry. An export-subsidy policy promotes the (rational) perception that a high-quality export can be provided at a relatively low price. Thus, an export subsidy generates a first-order benefit to...

This paper proposes a theory that predicts low levels of protection during periods of "normal" trade volume coupled with episodes of "special" protection when trade volumes surge. This dynamic pattern of protection emerges from a model in which countries choose levels of protection in a repeated...

High and declining prices signal a high-quality product. High prices are the efficient means of signaling, because the consequent loss of sales volume is most damaging for lower-cost, lower-quality products. As time passes and the number of informed consumers increases, the signaling distortion...
