In industries with imperfect consumer information, the lack of a reputation puts latecomers at a competitive disadvantage vis-à-vis established firms. We consider whether the existence of such informational barriers to entry provides a valid reason for temporarily protecting infant producers of experience goods and services. Our model incorporates both moral hazard in an individual firm's choice of quality and adverse selection among potential entrants into the industry. We find that infant-industry protection often exacerbates the welfare loss associated with these market imperfections.

This paper analyses trade in manuf acutured goods that are produced via a vertical production structure with many stages, where some value is added at each to an intermediate product to yield a good-in-process ready for the next stage. We consider the stage at which a good is traded to be an economically endogenous variable, with comparative advantage determining the pattern of production specialization by stages across countries. We study how endowment changes and policy shifts move the margin of comparative advantage, which thus provides a channel for resource allocation adjustment that is additional to the usual ones of factor substitution and changes in the quantity of output.

In this paper we analyze the determinants of international movements of physical capital in a model with uncertainty and international trade in goods and securities. In our model, the world allocation of capital is governed, to some extent, by the asset preferences of risk-averse consumer-investors. In a one-good variant in the spirit of the MacDougall model, we find that relative factor abundance, relative labor force size, and relative production riskiness have separate but interrelated influences on the direction of equilibrium capital movements. These same factors remain important in a two-good version with Heckscher-Ohlin production structure. In this case, the direction of physical capital flow is determinate (unlike in a world of certainty) and may hinge on the identity of the factor that is used intensively in the industry with random technology.

In this paper we study the determinants of intersectoral factor mobility. Mobility is the outgrowth of a prior investment decision. In particular, we focus on the human capital (i.e., training) decisions of workers. Uncertainty isa critical feature in such training decisions. The acquisition of general (vs. specific) skills allows a worker to select the more favorable sector after uncertainty is resolved. Thus general training has option value, which is enhanced by increases in risk. General training is a form of self-insurance. We study the impact of conventional insurance opportunities on training decisions. We find that the availabilty of income insurance does not necessarily imply less mobile workers.

What incentives do governments have to negotiate trade agreements that constrain their domestic regulatory policies? We study a model in which firms design products to appeal to local consumer tastes, but their fixed costs increase with the difference between versions of their product destined for different markets. In this setting, firms' profit‐maximizing choices of product attributes are globally optimal in the absence of consumption externalities, but national governments have unilateral incentives to invoke regulatory protectionism to induce firm delocation. An efficient trade agreement requires commitments not to engage in such opportunistic behavior. A rule requiring mutual recognition of standards can be used to achieve efficiency, but one that requires only national treatment falls short. When product attributes confer local consumption externalities, an efficient trade agreement must coordinate the fine details of countries' regulatory policies.

We study the incentives that governments have to protect intellectual property in a trading world economy. We consider a world economy with ongoing innovation in two countries that differ in market size and in their capacity for innovation. After describing the determination of national patent policies in a noncooperative regime of patent protection, we ask, “Why is intellectual property better protected in the North than in the South?” We also study international patent agreements by deriving the properties of an efficient global regime of patent protection and asking whether harmonization of patent policies is necessary or sufficient for global efficiency.

We characterize efficient self‐enforcing divisions of political or economic surplus between two parties that interact repeatedly. The party in power can decide the allocation, and the parties' political strength changes according to a Markov process. We find that the share of the party currently in power depends not only on its current strength but also on whether it had previously been even stronger since it last came to power. We find that the constitutional supermajority requirements that attempt to constrain the use of power can counterproductively create less compromise.
