In this paper, we examine the short-term and long-term effects of OPEC oil basket prices and natural gas on liquefied petroleum gas (LPG) traded on Energy Exchange of Iran. tests of convergence (integration) and causality of variables have been used for 2-year period, from May 22, 2014 to July 21, 2016. The results of the study based on long-term relationship show that an increase of 1 percent in the logarithm of OPEC oil basket prices decreases 17.24 percent of the logarithm of the price of LPG. The direction of causality is from OPEC oil basket prices to LPG. Moreover, 1% increase in natural gas prices logarithm will increase 26.52 percent of the logarithm of the price of LPG. The direction of causality is from natural gas to LPG. Estimating the relationship between short-term error corrections for the logarithm of the price of LPG also confirms no statistically significant error correction component.

Foreign aid is one of the most important policy tools that rich countries use for helping poor countries to improve population well-being and facilitate economic and institutional development. The concept of foreign aid orofficial development assistance (ODA) is widely used and accepted as a flow of financial resources from developed countries to developing countries on development grounds. However, the role and effects of foreign aid in the economic growth of developing countries have been and are controversial issues. This paper investigates the relationship between foreign aid and growth in per capita GDP using annual data from the 1980 to 2012 period for a sample of Iran. Three time series techniques (CCR, FMOLS and DOLS) were utilized to estimate the co-integrating equations. The results show that in long-run, effect of foreign aid on economic growth is positive, statistically significant, and sizable. Therefore, aid is more productive than domestic resources and other capital inflows.
