Economics analysts try to understand the economic world and then devise policies to try to improve it. Economic policy makers try to predict the outcome of alternative economic policies and evaluate them on a scale of better to worse by stating policy objectives and analysing policy outcomes according to political sentiments. An objective and scientific evaluation can be made of economic policy objectives such as efficiency, stability, growth and equity. Economic growth, in terms of incomes and productivity, is one of the main objectives of economic policy. Even in times of recession, economic performance is measured as a decrease in real GDP, or negative economic growth.
Growth transforms poor societies into rich ones but it has costs. The costs of growth are that in doing so it uses up exhaustible natural resources and might damage the environment. Two key factors that influence growth are technological advancement and capital accumulation. Devoting resources to one thing means they are not being devoted to anything else. There is always an opportunity cost. If resources are being used to discover new technologies and new forms of capital, they cannot be used to increase consumption goods and services or on current environmental concerns.
Growth can be measured in terms of the increase in real GDP. The periodic but irregular movement of economic activity we call the business cycle measures fluctuations of real GDP around potential GDP, the real GDP that could be produced if resources were fully employed. The economy has officially entered a recession and will eventually reach a 'trough' or turning point at which it will enter another phase of expansion. It is considered severe at the moment but is not expected to be as severe as a depression. Recessions are unpredictable as are animal spirits. One of the government's problems is closing the recessionary gap (Parkin, Powell and Matthews, 1997).
The current recession could be said to have global proportions. Globalisation means that process by which the production and marketing of products is becoming more integrated and interdependent (Harrison, Dalkiran and Elsey, 2000). As a result of this global economic interdependence the effects of the 'credit crisis' are being felt all over the world. The problem for the international institutions is that there is no model in finance, economics or international business theory that can explain or predict capital flows. The international institutions themselves may be out of date for the problems of the global environment. GATT has been replaced by WTO. The IMF was designed for a system that no longer exists. Internationally agreed policies may be required to curb the trend toward greater deregulation and international financial anarchy (Dawes, 1995).
Growth and population are often related. Rapid economic growth may be linked to rapid population growth. Real GDP per person is a measure of real GDP divided by population and can be used to compare growth rates across countries and over time. There may be similar features in productivity growth figures, business cycles and long-term trends in potential GDP in countries like the major OECD countries.
Long-term economic growth means expanded consumption possibilities, a better environment, pensions, welfare and more support for the poor and disadvantaged. When the rate slows the opposite effects and losses are felt. There is a relationship between the long-term growth rate and welfare and usually a trade-off between spending on welfare and on the productive sectors of the economy that generate growth. One of the biggest problems of macroeconomics is finding a balance of resource allocation between the two rival claims (Parkin, Powell and Matthews, 1997).
The scarcity of resources means that a frontier exists between what is attainable and unattainable in terms of production possibilities. Inward shifts along the frontier reduce our production possibilities and outward shifts expand the possibilities and resources are decreased and increased. Firms reduce production and prices for short-run equilibrium to eventually restore long-run equilibrium or they wouldn't be able to sell their products and customers buy what they need. Consumers may in fact be worried about their incomes and cut spending which would in turn leads to job losses, falling investment and a deepening of the recession. Consumer efficiency occurs when utility cannot be increased by reallocating their budgets. They should budget as wisely as ever for utility, preferences, indifference, substitutes and prices they can afford.
We can only continue to analyse the economic world, gain a greater understanding of how it works and devise institutions to that might improve economic performance. One thing is pretty sure, all the questions and answers will arise from scarcity (Parkin, Powell and Matthews, 1997).
