The Impact of Investment's Lags on Value Added in Different Industries

Investment is one of the most important factors in progress and development of countries. Since the required investment in various economic sectors or industries is different, some of industries are rapid-return and some of them are slow-return. Therefore, in order to determine which sector or industry should be placed on the development agenda if the decision-maker's goal is to get return more rapidly, it is necessary to have an appraisal from various industrie's lags, as far as investments lags are concerned. By using distributed lag Almon Model, this paper tries to estimate time lags for different sectors in Iranian industries during the 1350-1382 periods. The results show that the textile and clothing, wood product, cardboard and paper, food and drinking, and potpourri industries are rapid-return, while chemical, machine tool, metal, and non-metal mineral industries are slow-return. These results do contribute to decision-making and policy-making towards getting return more rapidly.
