The non-linear impact of oil price on the oil demand

ABSTRACT

A panel smooth transition regression model was adopted to analyse the non-linear impact of oil prices on oil demand. Data for 42 countries was obtained from the International Energy Agency for the time period spanning from January 1990 to June 2017. The results indicate that a threshold value does exist. Furthermore, when the oil price was lower than this threshold value, a positive relationship between oil price and oil demand was observed. When the price of oil was higher than the threshold value, however, a negative relationship between price and demand was found.     

Optimal regulation under imperfect enforcement: Permits,tickets, or both?

Economic activity is often regulated through both permits and tickets (subsequent inspections). We study the effectiveness of such policies where corruption and an underground economy make enforcement imperfect. In the theoretical model, asymmetric information justifies regulatory action which is enforced by corruptible bureaucrats. We find that regulation through permits alone is useless when corruption exists, while tickets still offer some benefit. Surprisingly, we also find that a system with both permits and tickets achieves welfare that is higher than that which can be achieved with only tickets—that combining the two mechanisms has an effect that is greater than the “sum of the parts.”     

COUNTING THE COST OF HIGHER BASE RATES

It is a brave Chancellor of the Exchequer who raises interest rates when inflation is at record low levels and there are few signs of overheating. But Kenneth Clarke is clearly trying to give substance to his commitment - made in June's Mansion House Speech - to pursue stable monetary and fiscal policies. In that speech, the Chancellor told his City audience that the government had "not created the conditions for the strongest recovery in Europe in order to throw it away by creating yet another boom followed by bust".
There is widespread agreement with the Chancellor's objectives. But the difficult question for economic management is how high interest rates will need to go in order to contain inflation and keep the economy on course. In this Forecast Release, we examine this question as well as assessing the likely impact of the first rise in base rates for five years.
