Knowledge management is frequently identified as an important antecedent of innovation. However, few empirical studies have specifically addressed antecedents and consequences of effective knowledge management. Today, domestic organizations are compelled, as well as other international organizations and have to compete to stay in business environment. Hence, they must be innovative. The purpose of this study is to evaluate the effect of knowledge management on employee's innovation in organizations through empowerment as a mediator for a case study of the Agricultural Bank of Qazvin province of Iran. Required information was gathered by a self-made questionnaire adapted and based on conceptual model adapted from previous studies. The population of this study consists of 369 employees of the Agricultural Bank of Qazvin. A total of 200 questionnaires were distributed, in which 188 valid questionnaires were collected. These questionnaires were distributed randomly among the male and female employees in branches of Agricultural Bank. The questionnaire is conducted by factor analysis and the reliability is measured by Cronbach's alpha. The structural equation modeling is used for data analysis. The results reveal the fact that empowerment will lead to employee's innovation. However, other variables did not have any significant and direct or indirect effect on employee's innovation.

Then the indexes related to these costs are evaluated based on the tax component, the cost of the sports, personnel costs and relationships among them.

The results show that the political cost, high free cash flow and low growth opportunity had negative correlations with each other. In other words, there was a negative relationship between profit and political costs in companies with high free cash flow and low growth opportunity.
