IMPACT OF PETROLEUM PRODUCT PRICE ON HUMAN WELFARE IN NIGERIA
The single most important issue confronting a growing number of world economies today is the price of oil and its attendant consequences on economic output. Therefore the study investigated the impact of petroleum pump price on human welfare in Nigeria over the period 1990 to 2015. The study employed expost facto research design. Secondary time series data were used for the study and these were sourced from World Development Indicator (WDI, 2015) and Central Bank of Nigeria statistical bulletin, (CBN, 2015). The data collected were analyzed using autoregressive distributed lag. The inferences were drown at 1% and 5% significance level. The result showed that premium motor spirit price and dual purpose kerosene price exert a long-run negative and significant impact on human welfare in Nigeria (β = -0.15299, t = -5.31141 and β = -0.471399, t = -1.8838 respectively) while premium motor spirit price, dual purpose kerosene price and inflation rate exert a short-run negative and significant impact on human welfare in Nigeria (β = -0.71735, t= -4.3766; β = -0.62562, t = -2.9188 and β = -0.050310, t = -2.1829 respectively). The study concluded that as premium motor spirit price and dual purpose kerosene price and inflation rate increases, human welfare will fall and vice versa. Therefore for human welfare to increase, there must be a fall in premium motor spirit price and dual purpose kerosene price and inflation rate in Nigeria. The study recommended that Government and it agencies should ensure that petroleum pump prices should be regulated because they have a long way on the market. An increase in the price of petroleum products will lead to market failure because most products use either of these products. Since inflation rate worsen the welfare of people, the policy maker should find a way of control inflation in the system so that the welfare of the people will improve (better-off).
