Abstract
Cocoa industry is vulnerable to price fluctuations
arising from fundamental changes in supply and demand and
other technical and social factors. Consequently, price
variability can affect the producers' returns and the
foreign exchange earnings. This study is undertaken to
investigate the main factors that determine cocoa prices.
Econometric cocoa models for the world and Malaysian
markets were developed and estimated using annual time
series data. Each model consists of supply, demand and
price equations, with stock as the identity. The analyses
and standard tests show that the models are satisfactory.
The R2 obtained for all the equations are above 0.75 and most coefficients have the correct signs. The RMS%E's are
all below 5 percent except for the world price equation
and Theil's inequality coefficients are all below 0.005.
Our result s show that domestic cocoa prices are
determined by prices prevailing in the world market.
Domestic stock change is not significant. In the world
market itself, stock and consumption are the main
factors that influence the behaviour of cocoa prices.
World consumption and export demand are significantly
influenced by the production index of the industrial
nations and price of cocoa. On the supply side, cocoa
production is determined by cocoa price lagged by the
gestation period. This implies that investment decision
on cocoa three to five years earlier is an important
factor that determines cocoa supply.
The effects of market fundamentals on cocoa prices
are further enhanced by the low price elasticities of
supply and demand. The effects are therefore substantial.
Owing to the importance of cocoa to the economies of
producing countries, it is therefore important to ensure
cocoa price stability, which may be achieved by efficient
price stabilization programmes. Such a programme can be
established through improvements of the existing'
buffer stock programme of the International Cocoa Agreement,
such as, for example, through proper stock management.
Promotion and down stream activities are alternative
instruments that can be exploited to encourage demand,
hence bolster cocoa price. Malaysia should therefore
support any programme that aims at stabilizing the world
cocoa price.
