Abstract
Operating in international market, the Iranian airline industry is one of the first organizations which have used IT in Iran, and therefore, a good case for analyzing the impact of IT on productivity at the firm level. In this study, we first estimate the productivity of the airline industry using the Iranian National Airline data from 1962 to 2000 by the Data Envelop Analysis (DEA) and the Stochastic Frontier Analysis (SFA) methods. We then evaluate the impacts of IT on the Iranian major Airline corporation.
Many different cases have been considered in estimating the productivity. In the DEA method, both constant and variable returns to scale have been applied. In the SFA method, different measures for output have been used from which the passenger- kilometer variable produced the most reasonable outcome. The results indicate that the productivity in the Iranian airline industry has been fluctuating within a fixed range before and after the period 1976-83 in which the productivity decreased dramatically, mostly due to the revolution and the Iraqi imposed war on Iran. Furthermore, IT has had a positive effect on the productivity since 1990.
