Burger and Smit found that the economies of key players in the natural rubber market both on the demand side and on the supply side were severely affected: substantially lower or even negative growth and dramatic declines in exchange rates.
This has resulted in turbulent developments in the natural rubber market in that period as well as in the year Burger and Smit showed that is a clear relationship between rubber consumption and GDP.
The natural rubber supply was not available in sufficient quantities at competitive prices. It was found that synthetic rubber prices tended to follow, rather than lead, natural rubber prices, as NR was the dominant price. Insufficient supply and high prices reduced the growth in consumption of natural rubber. Jit Yang Lim studied the short-term NR prices and evaluated the relative performance of 19 models based upon three different forecasting techniques, and four information sets.
The generalized autoregressive conditional heteroscedasticity regression or ARCH-type models are generally better than the simple regression models and the results can potentially be beneficial to participants in the NR futures market.
The impact of structural change, statonarity of the data and economic theory on energy modelling and forecasting, was investigated for Germany and UK, using two three-equation models which allowed for the long and short-run behaviour of the constituent variables Ian D.
The model were specified, restricted and estimated to comply with the above conditions and they were then used to generate one step ahead and dynamic forecasts from each of the two models; one with structural change, and the other without. In general structural change, stationarity of the data and economic theory were shown to have important implications for model specification and forecasting.

Jayasuriya, and C. Tan, presented a broad economic framework as depicted in Figure 3. It then interacted in a dynamic and recursive manner with demand.
Demand was set by the expected rubber price as well as by the income level in the overall economy, prices of rubber substitutes, and prices of final goods, technology, consumer preferences, stocks, and manufacturing capacity utilization.
They argued that the organizational structure of production, marketing and consumption, and government measures towards rubber were also important, but they entered the rubber framework through the mentioned supply and demand factors.

Econometric Models And Economic Forecasts
Vector Autoregression VAR Model The vector autoregression VAR is commonly used for forecasting systems of interrelated time series and for analyzing the dynamic impact of random disturbances on the system of variables Box and Jenkins, The VAR approach sidesteps the need for structural modeling by treating every endogenous variable in the system as a function of the lagged values of all of the endogenous variables in the system.
Since only lagged values of the endogenous variables appear on the right-hand side of the equations, simultaneity is not an issue and OLS yields consistent estimates. As an example, suppose that natural rubber production NRP and price of natural rubber P1 are jointly determined by a VAR and let a constant be the only exogenous variable. The VEC has cointegration relations built into the specification so that it restricts the long-run behavior of the endogenous variables to converge to their cointegrating relationships while allowing for short-run adjustment dynamics.
An ECM was developed in two stages.
First, a general autoregressive distribute lag equation was specified, which explains an endogenous variable by its own lags and current and lagged exogenous variables. To take the simplest possible example, consider a two variable system with one cointegrating equation and no lagged difference terms. The last term, one of the unique features of this approach, was called an error-correction term since it reflects the current "error" in achieving long-run equilibrium.
In long-run equilibrium, this term is zero. However, if and deviate from the long-run equilibrium, the error correction term will be nonzero and each variable adjusts to partially restore the equilibrium relation.
For forecast range from to For Baseline scenario from to We need to describe the nature and determine relationship of variables between them in terms of direction and strength or magnitude by using measures of central tendency indicated the location of the distribution Table 1.
They included the mean and median, and measures of dispersion show the dissimilarity of the values; these included standard deviation, minimum and maximum. The descriptive statistics also included measures of the shape of the distribution; skewness, kurtosis and Jarque-Bera test were displayed with their standard errors which provided evidence on normality.
Then, two components of normality were skewess and kurtosis. Skewness and kurtosis with their standard errors displayed the measures of the shape of the normal distribution. Therefore, the data were normally distributed and the data were good descriptive. Table 2 shows that seasonality tests and stationary tests. Seasonality tests were used to determine the effects of seasonal fluctuations. Seasonal fluctuations are an important source of variation in many time series data.
