When the components are replaced by the expressions determining them the result is: Y t = C 0 + G 0 + X 0 + (a+b)Y t-1 - aY t-2. A formula is needed to provide a quantifiable comparison between an amount today and an amount at a future time, in terms of its present day value. In an open economy. Net investment equals \$3 million (\$5 million gross – \$2 million depreciation). Investment banks may also provide guidance to companies who are considering issuing shares publicly for the first time, such as with an initial public offering (IPO). A)I = Y - C B)I … A)i. The national saving and investment identity provides a useful way to understand the determinants of the trade and current account balance. The lower the rate of inter­est, the higher is the present value, and vice versa. Thus, multiplier =∆Y/∆I =1/ 1-b equals marginal propensity to save (MPS) the value of investment multiplier is equal to 1/1-b = 1/s where s stands for marginal propensity to save. Lesson Summary. The formula for compound interest is P (1 + r/n)^ (nt), where P is the initial principal balance, r is the interest rate, n is the number of times interest is compounded per time period and t is the number of time periods. This equation is the corresponding relationship between investment (I) and saving (S) in an open economy (one that trades with the rest of the world). Learn vocabulary, terms, and more with flashcards, games, and other study tools. If the marginal propensity to consume is 0.8 or 80% then calculate the multiplier in this case.
