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

Human comfort in relation to sinusoidal vibration

An investigation was made to assess the overall subjective comfort levels to sinusoidal excitations over the range 1 to 19 Hz using a two axis electrohydraulic vibration simulator. Exposure durations of 16 minutes, 25 minutes, 1 hour, and 2.5 hours have been considered. Subjects were not exposed over such durations, but were instructed to estimate the overall comfort levels preferred had they been constantly subjected to vibration over such durations

The Nature of the ADAS Model Based on the ISLM Model

The aggregate demand and supply model (ADAS) is interpreted as a synthesis of the Keynesian and neoclassical models. It uses the ISLM model, without explaining its nature, to derive aggregate demand (AD). It is combined with an aggregate supply (AS) curve to explain price- inflation and output dynamics. This paper argues that neither the AD nor AS curve is conceptually the same as its microeconomic counterpart and ADAS is not a synthesis. In fact ADASimplies that discretionary policy is necessary and that price changes do not perform their traditional negative feedback function.eynesian and neo classical models, aggregate demand and supply, monetary policy rule, price adjustments, stabilization policy

The Relationship Between Growth and Investment

This paper utilizes the growth accounting framework to derive and analyze the relationship between the rate of growth of output and the ratio of investment to output. With plausible parametric assumptions this framework is used to examine the recent controversy in Fiji on investment and growth. Our results support the concerns of some USP economists that a 5% growth rate for Fiji needs significantly higher investment rates and institutional reforms.Investment ratio, Growth targets, Growth accounting, Total Factor Productivity.
