This study uses the results of a survey of entry level economists to investigate whether gender or age influence beginning salaries once other determinants of earnings are taken into account. We consider and control for terminal degree status, the quality of Ph.D. granting and hiring departments, field of specialization, costs of living across areas, and other institutional factors that can influence academic salaries. Gender is found to have no significant effect. Age seems to matter but only in departments that have faculty who do not publish in top journals and only through interactions with other variables.
U.S. urban transit systems receive operating and capital subsidies from various levels of government. Each firm minimizes its cost net of subsidies subject to its production function. The first order conditions from this minimization give a set of equations that are estimated using a stochastic frontier approach. From the results are calculated technical and allocative inefficiencies. The allocative inefficiencies are further decomposed among two sources, subsidies and factors internal to the firm. The analysis reveals large allocative inefficiencies between labor, fuel, and capital. Furthermore, it finds that subsidies lead to excess use of labor relative to capital and excess use of fuel relative to capital and labor. Also, most allocative inefficiencies in firms are due to internal factors and not subsidies, and the sizes of the inefficiencies vary substantially among transit firms.

This study extends the structural equations model to incorporate both revealed and stated preference data to analyze activity-based travel behavior. The model is applied to examine the relationship between activities and mode choice on the data from the first wave of the panel study conducted for the Puget Sound Regional Council. It is found that the attitude toward comfort of travel, car requirement for job, and travel time are significant predictors for the mode choice decision. Comparing alternative decision processes, the data support that the mode choice and activity choice decisions are affected by unobserved common factors, and the mode choice and the activity choice decisions are made independently. There is some evidence that the statedpreference model has the same model structure as the revealed-preference model, and the stated-preference data help improve the fit of the entire model.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
