Example of a positive externality is when a beautiful garden maintained by Mr. X raises welfare of Mr. Y even when Mr. Y is not paying for it. There is no valuation of it in the estimation of GDP.

It either underestimates or overestimates the level of welfare. Q.8 How should the following be treated in estimating national income of a country? You must give reason for your answer.

Non-monetary exchanges refer to such exchanges which do not involve the use of money, as a medium of exchange. In such exchanges, goods are exchanged for goods.. In economies like of India, barter system of exchange is not totally non-existent. Non-monetary transactions are quite evident in rural areas where payments for farm-labour are often made in kind rather than cash.

Thus, non-monetary exchanges make gross domestic product an inappropriate index of welfare. Q.10 How should the following be treated while estimating national income?
