This paper considers self-enforcing trade agreements among privately informed governments. A trade agreement that uses weak bindings (i.e., maximal tariff levels) is shown to offer advantages relative to a trade agreement that uses strong bindings (i.e., precise tariff levels). Consistent with...

I explore whether the world trading system of the twentieth century can be adapted to address the challenges of the twenty-first. I first develop an understanding of how GATT functioned during the twentieth century, and which features of the economic environment were most important in...

The design of a trade agreement should reflect its purpose. Does digital trade change the purpose of a trade agreement? To explore this question, I first describe the definitional and classification issues associated with digital trade, and for modeling purposes I adopt a simple taxonomy of the...

Current policies directed at mitigating global warming appear unlikely to prevent temperatures from rising to levels that would trigger a precipitous increase in the costs of climate change. Various attempts at international cooperation to avoid this outcome have failed. Why is this problem so...

The legitimacy of the world trading system is under growing attack, as challenges to its conformity with norms of fairness and social justice are increasingly voiced by citizens and their governments around the world. Taking a novel "bottom up" approach to concerns for fairness, we show how...

We formalize the GATT/WTO principle of reciprocity in workhorse quantitative trade models, characterizing reciprocal tariff cuts that hold terms of trade fixed and investigating their labor-market impacts. We provide closed-form expressions mapping reciprocal tariff cuts to labor market...

The primary predictions of strategic-trade theory are not restricted to imperfectly-competitive markets. Indeed, these predictions emerge in a natural three-country extension of the traditional theory of trade policy in competitive markets, once the theory is augmented to allow for...

To what extent must nations cede control over their economic and social policies if global efficiency is to be achieved in an interdependent world? This question is at the center of the debate over the future role of GATT (and its successor, the WTO) in the realm of labor and environmental...

Trade negotiations occur through time and between the governments of many countries. An important issue is thus whether the value of concessions that a government wins in a current negotiation may be eroded in a future bilateral negotiation to which it is not party. In the absence of rules that...

In his well-known analysis of the national debt, Robert Barro introduced the notion of a "dynastic family." This notion has since become a standard research tool, particularly in the areas of public finance and macroeconomics. In this paper, we critique the assumptions upon which the dynastic...
