In case the question requires us to explain influence of inflation on demand for money according to the portfolio theory.

Concept Introduction:

Portfolio theory: American economist James Tobin justified that rational individuals will keep portfolio of consisting of money (cash) and bond rather than keeping wealth either in money (cash) or bond. According to Tobin, people are in general risk averse. Human behaviour demonstrates risk aversion. This implies that, they have a preference towards lesser risk at a given rate of return. In the Keynesian analysis, the wealth of a person is either in the form of all money or all bonds depending on his expectation of the future rate of interest. According to Tobin, faced with various safe and risky assets, individuals prefer to diversify their portfolio by sharing their wealth in a balanced combination of safe and risky assets. According to him, an investor is confronted with a dilemma of what quantity of his portfolio of assets should be in the form of money (without any interest) and interest-earning bonds. Portfolio theory highlights the function of money as a store of value. Money presents a blend of risk and return as compared other assets which are less liquid than money — such as bonds.
