The main purpose of this paper is to investigate the nonlinear relationship betweentypes of intra-industry trade and inflation rate using the panel smooth transition regression model for selected developing countries during the period 2001-2016. In the framework of new trade theories, the relationship between intra-industry trade and inflation rate is not definite and clear, and the relationship depends on market structure, product differentiation and economies of scale and other factors such as tradeliberalization, exchange rate pass through, government size and human capital. For examining the relationship between types of intra-industry trade and inflation rate, two empirical models each in four cases have been used. In general, the results show that increases in vertical and horizontal intra industry trades reduce inflation rate which confirms the results of Krugman studies (1981, 1979). An increase in inflation also reduces vertical and horizontal intra-industry trades. According to the obtained results, it seems that enhancing intra-industry trade, especially horizontal one could improve foreign trade as well as control inflation.

The main purpose of this study is to investigate the effect of intra-industry trade on inflation for Iran during the period 1992-2017. Although in the framework of traditional trade theories, the effect of foreign trade on inflation is generally considered negative, studies over the topic based on new trade theories (NTT) are little and with no definite results. However, intra-industry trade seems to be able to moderate inflation through several ways, such as economies of scale and product differentiation. The results of estimate a smooth transition regression for Iran show that intra-industry trade in the form of a three-regime structure has a negative and significant negative effect on inflation. This finding is consistent with the Krugman models. Also, the results of the present study show that the effect of intra-industry trade on inflation rate has been non-linear and its presence accompanied with other factors has moderated the inflation. Based on the results, the policy recommendation of this research is to reform the structure of foreign trade in favor of intra-industry trade trade in such a way that while developing foreign trade based on comparative and competitive advantages, it is possible to adjust the inflation rate.

In this paper, we analyze the effect of lack of capital investment on energy projects using game theory in the guise of cooperative games. We focus on the energy projects in the provincial level as case study during 2010-2011. Therefore, we design a theoretical model of the lack of capital investment as a factor influencing the implement of energy projects. In the experimental section, we determine the pay-off cooperative game based on the equilibria obtained from case study, as well as using Nash bargaining solution. The results indicate that two players (government and private sector (contractor)) choose cooperative coalition since they take more gains rather than independent coalition of state. In this case, the government has higher bargaining power despite its lower discount rate, but contractor fears that the government performs projects with itself contractors. For this reason, the contractor will have lower bargaining power, and the government’s share in cooperative coalition will be higher.
