The theory of asset demand also stressed the function of money as the store of value. This theory elaborates why individuals demand one asset or typical portfolio of assets over the other alternatives.
What is Asset?
Asset is a valuable resources that individual or company owns. It has economic value and works as the store of value.
“An asset is a piece of property that is the store of value”.
The example of assets includes money, stock, bond, building, house, factory, car and so on and so forth. There are many ways people categorize assets based on underlying characteristics and features of assets. These characteristics and features may be the duration, tangibility, requirements, and so on. Therefore, the categories of assets may be any of the financial and nonfinancial assets, current and fixed assets, tangible and intangible assets, necessity and luxury assets and likely more others.
Why People Demand One Asset Over Other Assets?
Most probably, the answer is provided by the determinants of asset demand. There are many versions of theory of asset demand. However, the crux of all of these theories are more or less same in that there are four basic determinants of asset demand.
Wealth
Wealth is the total resources, including all assets, owned by owner. The wealthier the individuals, the more resources they possess to buy more assets. Therefore, increase in wealth leads to raise in demand for assets.
Expected Return
The expected return of an asset relative to alternative assets, over the next period, is another key determinant for the demand for asset. Precisely, the raise in expected return of asset relative to alternative assets leads to the increase in demand for that asset.
Risk
Risk is the degree of uncertainty associated to the return of typical asset. The higher the risk of asset, lower will be the demand for that asset.
Liquidity
Liquidity is the ease and speed in which one asset is converted into cash. The higher the liquidity of one asset, the more will be it’s demand.
When Theory of Asset Demand is Portfolio Theory of Money Demand?
This is when money, as an asset, is demanded. This is why, portfolio theory of money demand is also called theory of asset demand. Portfolio theory of money demand is actually the special case of theory of asset demand. This is because of the money being the focal asset under demand consideration. The portfolio approach to money demand accepts money as the store of value, and elaborates why money is demanded over other alternative assets in the portfolio.
The portfolio theory of money demand states that people will hold money as part of the portfolio of assets. The amount of money people will demand depends on return and risk on money relative to the risk and return on other alternative assets.
In figure above, there are 4 determinants of asset demand; all the determinants, but risk, are positively related to demand for asset as shown by respective arrows. Likewise, lower portion of figure shows the relationships between other determinants of money demand and demand for money.
Other Determinants of Money Demand
As in Keynesian theory of money demand, demand for real cash balance is positively related to real income and negatively related to nominal interest rate in portfolio theory of money demand. This is true primarily because of two reasons: First, income and wealth move together; when income is high, there will be high wealth to support high demand for money. Second, expected rate of return on money (equivalently the opportunity cost of holding money) will be high when the interest rate is high, so the demand for real money balance declines.
Now, lets point out the other determinants of money demand as follows:
Income
There is positive relationship between income and demand for money. The higher the income level, the higher will be the demand for money.
Interest Rate
There is negative relationship between interest rate and money demand. Higher rate of interest implies higher opportunity cost of holding money, and, hence, the demand for money declines.
Payment Technology
There is negative relationship between advancement of payment technology and money demand, because people need less money to settle the transaction.
Risk of Other Assets
Money demand and the risk of other assets are positively related. When the risk of other assets increases, money becomes relatively less risky compared to other assets, so the demand for money increases.
Inflation Risk
Investors don’t like to hold money when they perceive inflation risk, because money becomes relatively more risky. Instead, they prefer inflation hedges, assets whose real returns are less suffered to inflation, to holding money. When they hold Inflation hedges, their real returns are less affected than that of money when inflation rises.
Thus, there is negative relationship between inflation risk and demand for money.
Liquidity of Other Assets
Currency and checkable deposits are sometimes called dominated assets, because investors generally get higher return on other assets and still feel as safe as money. Moreover, even when the liquidity of other assets rise, money becomes relatively less liquid, so the demand for money falls.
Therefore, liquidity of other assets and demand for money are negatively related.
Conclusion
According to theory of asset demand, there are four basic determinants of asset that are wealth, expected return, risk and liquidity. Moreover, portfolio theory of money demand states that people hold money along with other assets in a portfolio. In line with Keynesian theory of money demand, portfolio theory insists on the function of money as a store of value.
Besides, there are also other determinants of money, a dominated asset. They are income, interest rate, payment technology, risk of other assets, inflation risk, and liquidity of other assets.
