The first chapter of this thesis studies the effect of labor unions on the elasticity of substitution between production inputs in several transportation industries such as railroad, postal service and air transportation. The elasticity is derived from two different methods: the CES production function and the translog cost function. This study finds that labor unions lower the flexibility to substitute between labor and capital in the air transportation industry. The second chapter estimates the effect of using internet job search on labor market outcomes. This study uses a Cox Proportional Hazard Model to find the effect of internet job search on unemployment duration. Further, a generalized Oaxaca wage decomposition is employed to explore a difference in wages received between internet job searchers and non-internet job searchers. The results show that internet job search is associated with higher education. However, there is no evidence that internet job search shortens unemployment duration of the job searchers. Finally, internet job searchers obtain slightly lower wages than non-internet job searchers. The last chapter in this dissertation studies the effect of New Economy Policy (NEP) on ethnics' economics gap in Malaysia. Specifically, this chapter estimates a degree of occupational segregation before and after NEP between ethnic Malays and Chinese, between ethnic Malaya and Indians, and between ethnic Chinese and Indians by using the Duncan Dissimilarity Index. In addition, this study also estimates a generalized Oaxaca wage decomposition between these ethnic groups before and after NEP. This study finds that NEP managed to reduce occupational segregation between all ethnic groups. However, all ethnic wage gaps continued to rise after 1986.
