This paper constructs a dynamic North–South trade model with outsourcing and endogenous innovation. Production of high quality goods is first performed in the North (Northern phase), then split between the North and the South (Outsourcing phase), and finally shifted to the South (Southern phase). This cycle is reignited whenever a Northern firm innovates a higher quality product. We find that an increase in the fraction of outsourced production raises the Northern skill premium unambiguously, while raising the Southern skill premium if and only if the skill intensity of outsourced production is higher than that of local Southern production.

A key goal of renewable resource managers in developing countries is to take actions to ensure that the resource being managed stays away from irreversible or crisis states, in which it provides neither consumptive nor non-consumptive services to humans. However, despite a manager's best efforts, the resource may still hit a crisis state. Therefore, given a particular management regime, it is useful to know how long it takes until the resource hits a crisis state. In this paper, the authors provide a theoretical analysis of this hitherto unstudied question. They first probabilistically delineate two management regimes. Next, they compute the expected time until crisis for both these regimes. Finally, they provide a numerical example to illustrate the working of their model and then discuss the implications of their findings for renewable resource management in developing countries.

This paper studies technology adoption in an optimal growth model with embodied technical change. The economy consists of the final good sector, the capital sector, and the technology sector which role is the imitation of exogenous innovations. Scarce labor resources are allocated to the technology and final good sectors. The final good is allocated to consumption and to the capital sector. The authors analytically characterize the long run optimal allocations. Using a calibrated version of the model, they find that an acceleration in the rate of embodied technical change should not be responded by an immediate and strong adoption effort. Instead, adoption labor should decrease in the short run, and the optimal technological gap is shown to increase either in the short or in the long run. The state of the institutions and policies around the technology sector is key in the design of the optimal adoption timing. [ABSTRACT FROM AUTHOR]
