Q.State and explain Say's Law of Markets. What did the classical economists conclude from it?

The core of the classical theory of employment is Say's Law of Markets — option (b).

In the Tamil Nadu HSC Class-12 Economics syllabus (Theories of Employment and Income), the classical theory of employment rests on Say's Law of Markets, which states that "supply creates its own demand." It means that the act of producing goods generates enough income to buy those goods, so there can be no general overproduction or lasting involuntary unemployment; the economy automatically tends to full employment.

Flexibility of the rate of interest brings about equality between savings and investment (classical view).

In the classical theory of employment, saving and investment are both functions of the rate of interest. Saving rises when the interest rate is high (people are rewarded more for saving), while investment rises when the interest rate is low (borrowing is cheaper). If saving exceeds investment, the interest rate falls, discouraging saving and encouraging investment; if investment exceeds saving, the interest rate rises, doing the opposite.

Through this flexibility of the rate of interest, the two are automatically brought into equality, ensuring full-employment equilibrium. Capital, demand and supply flexibility do not perform this specific balancing role in the classical model.

Classical economists regarded the rate of interest as a reward for saving, so option (c) is correct.

This is a core idea in the theories-of-employment topic of the Tamil Nadu HSC Commerce syllabus. In the classical theory, the rate of interest is determined by the demand for and supply of capital (savings). Saving involves sacrificing present consumption, so the interest paid is the reward for this abstinence or 'waiting'.

Interest thus balances savings (supply of loanable funds) with investment (demand for funds). This contrasts with Keynes, who treated interest as a purely monetary reward for parting with liquidity.

Hence interest is not a reward for capital, investment or demand as such, but specifically for saving.

The classical theory of employment is built on Say's Law of Markets, so option (a) is correct.

In the theories-of-employment topic of the Tamil Nadu HSC Commerce syllabus, the classical theory is founded on Say's Law of Markets, propounded by J.B. Say. Its central proposition is that 'supply creates its own demand' — the act of producing goods generates enough income (wages, rent, interest, profit) to buy back the entire output.

Because of this, the classical economists argued there can be no general overproduction or lasting involuntary unemployment; the economy automatically tends towards full employment. This makes the Law of Markets the very core of the classical theory, not the law of diminishing returns, consumption or demand.

J.B. Say was a classical economist, so option (d) is correct.

Jean-Baptiste Say was a French economist of the classical school. His famous 'Law of Markets' — that supply creates its own demand — is a cornerstone of classical employment theory, which assumes full employment as the normal state of the economy. He was neither a modern nor a neo-classical economist.

Say's law assumes full employment of resources, so option (b) is correct.

Say's Law of Markets states that 'supply creates its own demand' — the act of producing goods generates enough income to buy them, so there can be no general overproduction. This is a classical proposition that assumes the economy is normally at full employment, with perfect competition and flexible prices/wages. It rules out involuntary unemployment, which is exactly what Keynes later criticised.

J.B. Say was a classical economist.

Jean-Baptiste Say (1767–1832) was a French economist of the classical school. His most famous contribution is Say's Law of Markets, which states that 'supply creates its own demand' — the act of producing goods generates enough income to buy all that is produced, so there can be no general overproduction or lasting unemployment. This idea was central to classical employment theory until Keynes challenged it.
