In the model there are n industries producing n di erent products such that the input equals the output or, in other words, consumption equals production. Thus the down­ward sloping demand curve, for example, can be deduced from general assumptions about how people try to maximise their satisfaction from the purchase of goods and services.

The stressful economical condition creates uncertainty among investors (both domestic and foreign) to wait some time and look for future opportunities.
