In oil-exporting countries, it is important to have a clear evaluation of the oil sector at the national and regional levels. In input-output literature, the traditional and extraction methods are often used to analyze the status of economic sectors. These methods have two major shortcomings: double-counting of linkages and having a flaw to show the changes in income of the labor. In this paper, to overcome these shortcomings and to provide a more realistic picture of the status of the oil sector at national and regional levels, a comparative comparison has been used between Iran and Canada focusing on their two major oil-exporting provinces, Khuzestan and Alberta. For this purpose, the production-to-production approach based on the Sraffa-Pasinetti-Leontief theoretical model which its main concept is the induced effect of value-added will be used. The results show that the oil sector creates 0.0435 and 0.0372 units of induced value-added in Iran and Khuzestan. In Canada and Alberta the corresponding figures are 0.3173 and 0.4382. Therefore, this sector has more interdependency with the other sectors in both national and regional levels in Canada (as a well-developed country) than Iran (as a developing country). However, services and industry sectors absorbed more decomposed induced value-added of the oil sector in comparison to other sectors. Therefore, national and regional policies should be implemented to have diversified products and prepare the requirement of having the most of interdependency prerequisites between the sectors.

Improving food security status through socio-economic determinants is always important at the household level. In this study, after assessing the food security level of households in urban and rural areas of Khuzestan province, associated factors including economic, social, and racial with food security were identified in 1397. To achieve the goals, 1876 and 1495 questionnaires were collected in urban and rural areas respectively. The logistic regression model was used to identify effective factors. The results showed that 63 % and 68 % of households in urban and rural areas face food insecurity respectively. Hamidiyeh county with 18 %, Omidieh 25 % , and Dezful 28 % had the least percent of food secured households in the urban areas of Khuzestan province, respectively. Also, the cities of Shadegan with 13 %, Izeh with 15 %, and Mahshahr port with 18 % had the least percent of food security households in rural areas, respectively. The results of the quantitative estimated model in the present study showed that employment of the head of the household, income, number of rooms and personal car ownership were significantly and directly associated with food security in urban and rural areas of Khuzestan province. Therefore, due to the weakness of income policies which are applying as the only ways to ameliorate food security status in Iran, paying close attention to socio-economic factors related to improving the level of household food security before any intervention is necessary.

This paper analyzes the industrial activities and their actual comparative advantages in Khuzestan province using two digits ISIC cods and DRC criterion for the period 1377-82 (1998-2003). The results show that international competitiveness of industrial activities has been improved since 1381, the time of implementation of exchange rate unification and relative economic liberalization policies in Iran.
This paper also suggests a simple decomposition of DRC measure to isolate the determinant elements of international competitiveness of some industrial activities under consideration. These elements are: (1) government intervention in economy, (2) factor cost, (3) factor proportions and (4) total factor productivity. The results imply that alleviation of the size of government interventions in economy has the most important role in improving the competitiveness of industrial activities in most cases.

This paper deals with estimation and analysis of demand for labour in Khuzestan's manufacturing. First, we estimate the stock of capital applying exponential trend method. Employing Johansen’s approach, the research investigates the long-run effect of significant determinants on demand for labour in Khuzestan’s manufacturing for the period 1966-2002. The findings indicate that in the long run, stock of capital and productivity of capital affect positively the demand for labour, while the average capital has negative effect. The result also shows that the error correction term is negative and less than one (-0.95) indicating that the speed of adjustment toward equilibrium in response to deviations from the long-run equilibrium is very high.

This paper aims to estimate labour productivity in Khuzestan's industries during 1971-2001. To this end a generalized Cob-Douglas model is applied in which capital stock, gap between actual and potential output and research cost are independent variables. Since the data on the fist two variables were not available, two methods, i.e., exponential trend of investment and Intriligator method, were applied to generate them. The findings of the research show that labour productivity has direct relationship with capital stock as well as research cost, but indirect relationship with output gap.

Due to the importance of production of pipes in oil and gas industries, the estimation of oil and gas pipe production function is of great interest. To this end, Ahvaz pipe mill, the largest pipe mill in Iran, has been chosen as a case study and its production function during 1979-2003 has been estimated. This estimation is based on time-series techniques, using unit root tests, cointegration and error correction models. The results suggest that Cobb-Douglas production function is more compatible with theory of production function & the data than alternative specifications. The imperical findings show that the error correction term is 0.96, labour elastisity and capital elastistiy are 0.58 and 0.53, respectively. The wald test result indicate that there is increasing return to scale.
