Cointegration and the demand for gasoline

Since the early 1970s there has been a worldwide upsurge in the price of energy and in particular of gasoline. Therefore, demand functions for energy and its components like gasoline have received much attention. However, since confidence in the estimated demand functions is important for use in policy and forecasting, following Amarawickrama and Hunt (2008), this paper estimates the demand for gasoline is estimated with 6 alternative time series techniques with data from Fiji. Estimates with these 6 alternative techniques are very close and thus increase our confidence in them. We found that gasoline demand is both price and income inelastic

ARE US GASOLINE PRICE ADJUSTMENTS ASYMMETRIC?

We use the LSE-Hendry general to specific approach to analyse if US gasoline price adjustments are asymmetric with respect to changes in crude oil prices. Furthermore, we modify some weaknesses in the earlier works by Boreinstein, Cameron and Gilbert (1997) and Bachmeier and Griffin (2003) and shows that if the price adjustment equations are properly specified and estimated, alternative specifications and temporal aggregation of data do not affect the results. Monthly US data are used to show that alternative specifications give equally good results and there is no asymmetry in the US gasoline price adjustments.Asymmetric price adjustments, Market power, General to specific approach, Error correction models and Gasoline and crude oil prices

Lending trends in the sugar cane sector

The paper looks at the trends in grower indebtedness and investment in the sugar cane sector. Data shows that there has been a declining trend in formal sector loans made out to sugar cane growers. This indicates a declining investment levels in sugar cane production section of the sugar industry
