Investment Function
The investment function is a summary of the variables that influence the levels of aggregate investments. It can be formalized as follows: I=f(r,ΔY,q) - + + where r is the real interest rate, Y the GDP and q is Tobin's q. The signs under the variables simply tell us if the variable influences investment in a positive or negative way (for instance, if real interest rates were to rise, investments would correspondingly fall). The reason for investment being inversely related to the Interest rate is simply because the interest rate is a measure of the opportunity cost of those resources. If the resources instead of financing the investment could be invested in financial assets, there is an opportunity cost of (1+r), where r is the interest rate. This implies higher investment spending with a lower interest rate. When GDP Gross domestic product (GDP) is a moneta ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Investment
Investment is the dedication of money to purchase of an asset to attain an increase in value over a period of time. Investment requires a sacrifice of some present asset, such as time, money, or effort. In finance, the purpose of investing is to generate a return from the invested asset. The return may consist of a gain (profit) or a loss realized from the sale of a property or an investment, unrealized capital appreciation (or depreciation), or investment income such as dividends, interest, or rental income, or a combination of capital gain and income. The return may also include currency gains or losses due to changes in the foreign currency exchange rates. Investors generally expect higher returns from riskier investments. When a low-risk investment is made, the return is also generally low. Similarly, high risk comes with a chance of high losses. Investors, particularly novices, are often advised to diversify their portfolio. Diversification has the statistical effec ...

Interest Rate
An interest rate is the amount of interest due per period, as a proportion of the amount lent, deposited, or borrowed (called the principal sum). The total interest on an amount lent or borrowed depends on the principal sum, the interest rate, the compounding frequency, and the length of time over which it is lent, deposited, or borrowed. The annual interest rate is the rate over a period of one year. Other interest rates apply over different periods, such as a month or a day, but they are usually annualized. The interest rate has been characterized as "an index of the preference . . . for a dollar of present ncomeover a dollar of future income." The borrower wants, or needs, to have money sooner rather than later, and is willing to pay a fee—the interest rate—for that privilege. Influencing factors Interest rates vary according to: * the government's directives to the central bank to accomplish the government's goals * the currency of the principal sum lent or borrowed * ...

Opportunity Cost
In microeconomic theory, the opportunity cost of a particular activity is the value or benefit given up by engaging in that activity, relative to engaging in an alternative activity. More effective it means if you chose one activity (for example, an investment) you are giving up the opportunity to do a different option. The optimal activity is the one that, net of its opportunity cost, provides the greater return compared to any other activities, net of their opportunity costs. For example, if you buy a car and use it exclusively to transport yourself, you cannot rent it out, whereas if you rent it out you cannot use it to transport yourself. If your cost of transporting yourself without the car is more than what you get for renting out the car, the optimal choice is to use the car yourself. In basic equation form, opportunity cost can be defined as: "Opportunity Cost = (returns on best Forgone Option) - (returns on Chosen Option)." The opportunity cost of mowing one’s own la ...

Tobins Q
Tobin's q (or the q ratio, and Kaldor's v), is the ratio between a physical asset's market value and its replacement value. It was first introduced by Nicholas Kaldor in 1966 in his paper: ''Marginal Productivity and the Macro-Economic Theories of Distribution: Comment on Samuelson and Modigliani''. It was popularised a decade later by James Tobin, who in 1970, described its two quantities as: Measurement Single company Although it is not the direct equivalent of Tobin's q, it has become common practice in the finance literature to calculate the ratio by comparing the market value of a company's equity and liabilities with its corresponding book values, as the replacement values of a company's assets is hard to estimate: :Tobin's q = \frac It is also common practice to assume equivalence of the liabilities market and book value, yielding: :Tobin's q = \frac. Even if market and book value of liabilities are assumed to be equal, this is not equal to the "Market to Book Ratio" ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
