The process of economic development is characterized by substantial reallocations of resources across sectors. In this paper, we construct a multi-sector model in which there are barriers to the movement of labor from low-productivity traditional agriculture to modern sectors. With the barrier in place, we show that improvements in productivity in modern sectors (including agriculture) or reductions in transportation costs may lead to a rise in agricultural employment and through terms-oftrade effects may harm subsistence farmers if the traditional subsistence sector is larger than a critical level. This suggests that policy advice based on the earlier literature needs to be revised. Reducing barriers to mobility (through reductions in the cost of skill acquisition and institutional changes) and improving the productivity of subsistence farmers needs to precede policies designed to increase the productivity of modern sectors or decrease transportation costs.

Regulatory reform in the late 1970s and early 1980s vastly transformed the labor market for transportation workers. Most research in this area focuses on the effect of deregulation on the earnings of nonmanagement company workers in airline, trucking and rail. Deregulation of transportation industries, though, has had a broader effect on workers. For instance, deregulation also influences workers' hours worked per week, working conditions, worker safety, and a host of other labor issues. Deregulation might also influence the earnings of managers and self-employed workers in transportation industries. Examining these issues is valuable because such analysis provides a more complete assessment of labor market changes following the shift to a more market oriented business environment. Transportation Labor Issues and Regulatory Reform adds to the debate on deregulation's influence on transportation labor markets by presenting empirical evidence on an array of labor market outcomes in transportation industries. Contributions to this volume are categorized by their analysis on worker safety, working conditions and employment opportunities, and by their analysis on managerial and self-employed earnings
