The Keynesian Theory of Income and Employment applies the income-expenditure model of the economy. It is also based on the aggregate demand-supply model. This article will explore the income-expenditure model and Hicks’ generalization of the marginal propensity to save.
Keynes’s income-expenditure model
Keynes’s income-expendit model can be summarized as follows: the economy grows by spending money, and the total amount of money spent is equal to the total amount of money produced. It is possible to estimate the size of the economy by measuring the real GDP.
Keynes’s income-expendit model shows that a change in aggregate demand is the biggest factor affecting GDP and employment. Government and consumer spending both increase output, as do investments and exports. If a change in any component of the economy increases output, it is called a Keynesian multiplier. It is important to note that the multiplier is more than one.
Hicks’ generalization of the propensity to save
Keynes’s general theory of income and employment is based on the relationship between saving and investment. He believed that the incentive of entrepreneurs to invest fails to keep pace with the propensity of society to save. Because of this, Keynes believed that the propensity to save and the propensity to invest must be roughly equal. Thus, incomes must fall below a certain level for the desire to save and the incentive to invest to maintain them. In other words, in order for the economy to recover from a recession, people must be able to save.

Unlike the classical theory, Keynes’ generalization of the propensity to keep money for the future takes both income and interest rates into account. This makes Keynes’ system more flexible and explains why saving is necessary for the economy to function. In the classical theory, saving was seen as an indirect way of purchasing capital goods and thus a factor in the overall balance of the economy.
Hicks’ generalization of the marginal propensity to save
The Hicks’ generalization of the marginal preference to save is an important part of the Keynesian theory of income and employment. It is a key departure from classical economics. In the Keynesian model, the marginal propensity to save and consume equal the total income of a country. The point where the two curves intersect is referred to as equilibrium income.

The key difference between Keynes’ original theory and the Hicks’ generalization is the inclusion of the marginal propensity to save and spend. Hicks shows that money demand is dependent on income and the interest rate. Keynes has never fully integrated the second liquidity preference doctrine, but John Hicks did, and the IS-LM model is one example.
Hicks’ rejection of Say’s Law
Hicks’ rejection of Say’s law is a crucial part of the Keynesian theory of income and employment, as it demonstrates that income and employment are highly interdependent. Interest rates and the value of an investment determine the volume of employment and the rate of interest determines the quantity of money. As a result, the value of an investment determines the rate of interest, and the value of income is determined by the multiplier.

Say’s Law supports laissez-faire economics, which argues that the more production, the more prosperity. In addition, it rejects the idea that low consumption limits the quantity of the final product.
