Forward-looking investments determine the resilience of firms' supply chains. Such investments confer externalities on other firms in the production network. We compare the equilibrium and optimal allocations in a general equilibrium model with an arbitrary number of vertical production tiers....

We examine integration strategies of multinational firms that face a rich array of choices of international organization. Each firm in an industry must provide headquarter services from its home country, produce intermediate inputs, and assemble the intermediate goods into final products. Both...

We study the determinants of the extent of outsourcing and of direct foreign investment in an industry in which producers need specialized components. Potential suppliers must make a relationship-specific investment in order to serve each prospective customer. Such investments are governed by...

This paper proposes a method for separating economic time series into a smooth component whose mean varies over time (the trend') and a stationary component (the cycle'). The aim is to make the trends as smooth as possible while also producing cycles with plausible properties. While the main...

In industries with imperfect consumer information, the lack of a reputation puts latecomers at a competitive disadvantage vis-a-vis established firms. We consider whether the existence of such informational barriers to entry provides a valid reason for temporarily protecting infant producers of...

We study the positive and normative effects of counterfeiting, i.e.,trademark infringement, in markets where consumers are not deceived by forgeries.The fact that consumers are willing to pay more for counterfeits than for generic merchandise of similar quality suggests that they value the...

We study a simple, two-stage, stochastic patent race involving two firms. We examine the behavior of the participants as they gain the lead or fall behind in the race. We find that the leader engages in R&D more intensively than does the follower, and that both firms intensify their efforts if...

We study the optimal pattern of outlays for a single firm pursuing an R&D program over time. In the deterministic case, (a) the amount of progress required to complete the project is known, and (b) the relationship between outlays and progress is known. In this case, it is optimal to increase...

In this paper we ask whether a policy of targeted export promotion can raise domestic welfare when several oligopolistic industries all draw on the same scarce factor of production. Our point of departure is one of Cournot duopoly in which a single home firm competes with a single foreign firm...
