Explain specific historical analogy of business forecasting This theory is hazed on a more realistic assumption, that all business cycles are not uniform in amplitude or duration and as such the use of history is made not by projecting any fancied economic rhythm into the future, but by selecting some specific previous situation which has many of the earmarks of the present and concluding that what happened in the previous situation will happen in the present one also. What is done is that a time series relating to the data in question is thoroughly scrutinized and from it such period is selected in which conditions were similar to those prevailing at the time of making the forecasts. The course which events tool in the past under similar circumstances is then studied which gives an idea of the likely course which the phenomenon in question would follow.

Explain specific historical analogy of business forecasting

This theory is hazed on a more realistic assumption, that all business cycles are not uniform in amplitude or duration and as such the use of history is made not by projecting any fancied economic rhythm into the future, but by selecting some specific previous situation which has many of the earmarks of the present and concluding that what happened in the previous situation will happen in the present one also. What is done is that a time series relating to the data in question is thoroughly scrutinized and from it such period is selected in which conditions were similar to those prevailing at the time of making the forecasts. The course which events tool in the past under similar circumstances is then studied which gives an idea of the likely course which the phenomenon in question would follow. For example, after world war many persons forecast a depression because world war. I had followed by a depression.

 Explain economic rhythm theory of business forecasting

The basic assumption of this theory is that history repeats itself and hence the exponents of this theory believe that economic phenomena behave in a rhythmic order. Cycles of early the same intensity and duration tend to happen again. Thus, the available historical data have to be analysed into their component parts and different types of fluctuations. Influencing them has to be separated out. A trend is then obtained which will represent a long-term tendency or growth of decline. This trend line is projected a number of years into the future either by the freehand method or by the mathematical method. This is done on the assumption that the trend line represents the normal growth or decline of the series.

Explain action and reaction theory of business forecasting

This theory is based on two assumptions (1) every action has a reaction and (2) magnitude of the original action influences the reaction. Thus if the price of wheat has gone up above a certain level in a certain period, there is likelihood that after some time it will go down below the normal level, thus, according to this theory a certain level of business activity is normal-sub normal or abnormal conditions cannot reaming so for ever- there is bound to be reaction to them. Thus, we find four phases of a business cycle:    1. Prosperity2. Decline.3. Depression and4. Improvement.

Explain sequence or time-lag theory of business forecasting

This is the most important theory of business forecasting. It is based on the assumption that most of the business data have the lead relationship changes in business are successive and not simultaneous. There is time-lag between different movements, for example, expenditure on advertisement may not at once lead to increase in sales. Similarly, hen government makes use of deficit financing it leads to inflationary pressure-the purchasing power of people goes up-the wholesale prices. The retail prices start rising. With the rise in retell prices the cost of living goes up and with it there is a demand for increased wage. Thus, one factor, more money in circulation, has affected various fields of economic activity not simultaneously but successively, similarly, when the excise duties are increased by the government they result in increases in prices which would lead to higher demand for wages.
