Economic Impact of Climate Change on Wheat and Cotton in Major Districts of Punjab
Authors: Noman Arshed ; Shukrillo Abduqayumov
The long run impact of climate change on the productivity of major crops in the districts of Punjab is analyzed for the time period of 1970 to 2010. This study used deviations from average maximum annual temperature and deviations from average rainfall are used as indicators for climate change. While other variables include sale price, fertilizer use and number of tube wells. In order to incorporate long timer periods, this study used Panel ARDL model. The results show that cotton productivity is more positively sensitive to price changes; an increase in temperature, tube wells and fertilizers while wheat productivity is more positively sensitive to the rainfall in the long run. Consequently, in the short run, wheat productivity equilibrium is faster converging. Hence deviations from average rainfall are harmful to cotton crop in the long run and cotton & wheat in the short run, while deviations in maximum temperature is only harmful for cotton crop in the short run.
Economic Growth of Nigeria: Does Oil Revenue Matters?
Authors: Musa Adeiza Farouk ; Bashir Mohammed Nafiu ; Aliyu Saidu
Oil, a very versatile and flexible non-productive, depleting, natural (hydrocarbon) resource is a fundamental input to modern economic activities providing about 50 percent of the total energy demanded in the world apart from the former centrally planned economy. The countries dealing with oil exploiting in the world depend heavily on oil revenue for foreign exchange earnings and for the government budget, in most cases, reaching 90 percent or above. Few studies have been carried out in this regard yet there is no conclusion as to the key factors that determine economic growth. This study determines the influence of Oil revenue on economic growth of Nigeria. The study uses domestic consumption and export as proxies for Oil revenue, and represents economic growth with real gross domestic product. Using 33 years time series observations, the study used Ordinary least square method. The study covers the period from 1980 to 2013. Secondary data source was acquired from the central Bank of Nigeria (CBN) Statistical bulletin. The study found that both domestic consumption and export has positive and significant influence on economic growth of Nigeria. The study recommends that, the domestic consumption and crude oil export sales should be increased in order to have the gross domestic product increased as this will put the country on a better scale. But this will have to be done by balancing the domestic consumption with the export of oil.
