The large literature on labor‐market rent sharing consists of closed economy analyses. In this article we examine whether profits are shared across borders and also conditioned by international linkages that help shape economic openness. In a sample of 1,014 Canadian manufacturing union contracts from 1980 through 1992, we find that U.S. industry profitability affects Canadian wage outcomes and that the pattern of rent sharing varies significantly across international linkages, including multinational ownership, union type, and trade barriers. There seems to be international rent sharing, with profit sharing across borders conditioned by firm‐ and industry‐level institutions.

Using Current Population Survey data for 1983-93, this article analyzes whether there is a union membership wage premium among full-time, private sector employees covered by union contracts. Ordinary least squares estimates of the membership wage premium are 12%-14%, and allowing membership to be endogenous yields larger estimates. Differences in job tenure, unobservable characteristics, and measurement error cannot fully explain the estimated premium. Significant differences in this premium, as well as in membership rates conditional upon coverage, across various demographic subgroups are also documented. In general, "free riders" do not appear to be free riding.

We use a unique firm-level panel data set of multinational parents and their foreign affiliates to analyze whether profits are shared across borders within multinational firms. Using both fixed-effects and generalized method-of-moments estimators, affiliate wage levels are estimated to respond to both affiliate and parent profitability. The elasticity of affiliate wages to parent profits per worker is approximately 0.03, which can explain over 20 percent of the observed variation in affiliate wages. These results reveal a previously ignored aspect of labor-market rent sharing. They also reveal an important micro-level linkage with potential macro-level implications. International rent sharing can transmit economic conditions across national borders, and can thereby provide an implicit cross-country risk-sharing mechanism.
