The Motorization and Decline of Urban Public Transit, 1935–1950
比较了1935-1950年间内燃机公交车与电动有轨电车、电动公交车的成本和利润，发现内燃机公交车在经济上处于劣势，支持了城市公共交通衰落与有组织排挤有关的主张。
Were intracity motor buses economically inferior to electric streetcars and electric buses in the late 1930s and l940s? The contention that they were has recently served as the basis for allegations that the decline of urban public transit was attributable, in large part, to an organized campaign intent on eliminating viable public transit. Aggregate data from trade sources allows a comparative cost and profit analysis of motor buses, electric buses, and electric streetcars for the years 1935–1950. The analysis supports the contention that motor buses were inferior. Questions regarding the applicability of criticisms of market foreclosure theory are also considered.
