The multiplier effect
This is defined as the expansion of a country's money supply as a result of banks being able to lend. The size of the multiplier effect depends on the percentage of deposits that banks are required to hold on reserves. In other words, it is money used to create more money and calculated by dividing total bank deposits by the reserve requirement.
The multiplier effect depends on the set reserve requirement. To calculate the impact of the multiplier effect on the money supply it is necessary to start with the amount banks initially take in through deposits and divide by the reserve ratio. If, for example, the reserve requirement is 20 per cent, for every $100 a customer deposits into a bank, $20 must be kept in reserve.
However, the remaining $80 can be loaned out to other bank customers. This $80 is then deposited by these customers into another bank, which in turn must also keep 20 per cent, or $16, in reserve but can lend out the remaining $64. This cycle continues - as more people deposit money and more banks continue lending it - until finally the $100 initially deposited creates a total of $500 ($100/0.2) in deposits. This creation of deposits is the multiplier effect.
The higher the reserve requirement, the tighter the money supply, which results in a lower multiplier effect for every dollar deposited. The lower the reserve requirement, the larger the money supply, which means that more money is being created for every dollar deposited.
Reliance on commodity exports
Too many developing countries rely on commodity exports (often only one or two goods) but are still importers of higher value final products. The manufacturing of products means money that is used to pay for labour and materials moves through the economy creating the multiplier effect.
Developing countries primarily exporting raw materials and commodities lessen the circulation of money and ultimately create an imbalance in trade between rich and poor.
The issue of poverty will form a major focus of the Humanitarian Development Summit, concentrating on the required structural adjustments along with the technology transfer needed to allow developing countries to not just trade fairly but trade in the world’s higher value markets.
