Fiscal policy is government manipulation of it's expenditure and revenue variable with the view of achieving a given set of macro economics

Despite the superiority of the optimum theory over the Malthusian theory of population, it has its weaknesses.
<ol>
<li>No Evidence of Optimum Level: The first weakness of the optimum theory is that it is difficult to say whether there is anything like an optimum population. There is no evidence about the optimum population level in any country.</li>
<li>Impossible to Measure Optimum Level: It is impossible to measure the optimum level quantitatively. As pointed out by Prof. Bye, it is “impossible to calculate it with any semblance of exactness for any country at any time”.</li>
<li>The theory does not explain how the optimum level, once reached, is managed.</li>
<li>Another difficulty pertains to the measurement of per capita income in the country. It is not an easy task to measure changes in the per capita income. The data on per capita income are often inaccurate, misleading, and unreliable which make the concept of optimum as one of doubtful validity.</li>
<li>No Place in State Policies: The concept of optimum population has no place in the policies of modern states. While fiscal policy aims at increasing or stabilising the level of employment, output and income in a country, no reference is made to the optimum level of population. This theory is therefore, of no practical use and is regarded as useless.</li>
