Following the Calvo(1978) model, the equilibrium urban wage rate is determined by the mechanism of bargaining process between a monopolistic urban trade union and urban firms. An exogenous shock of urban technological progress, through the bargaining mechanism, always increase the urban-rural wage gap and the urban uniemployment; while it always decreases the rural employment. However, its effect on the urban employment is shown to be generally ambiguous. Moreover, it is shown that the urban technological progress always increases the social welfare (defined by social utility function), although it exacerbates the social income inequality (measured by movements in Lorenz curve).}, pages = {15--31}, title = {Urban-Specific Technological Progress in a Harris-Todaro Model with an Oligopolistic Urban Sector}, volume = {58}, year = {2010} }
