Gdp problems and solutions pdf

the GDP is proportional to the current GDP x(t) = gx(t), where t stands for time and i(t) the derivative of the hction x with respect to t. The growth rate of the GDP is xlx. If the growth rate g is given at any time t, the GDP at t is given by solving the differential equation. The solution is x(t) = x(o)eg'. Economic Principles Solutions to Problem Set 3 Question 1 The WARP requires that, if a bundle x 0 is chosen when another bundle x 1 is available, then when this new bundle x 1 is itself chosen, x 0 must not be available. Assuming budget balancedness, wi = pixi (a) w0 = p0x0 = 10, p0x1 = 6, w1 = p1x1 = 14, p1x0 = 22 Since w0 > p0x1 and w1 < p1x0, WARP is satis-ed. (b) w0 = p0x0 = 40, p0x1 Suppose G=150 and P=1. We simply need to solve the following system of equations: r = 25 + (150/10) -(Y/40). 2 r = (Y/20) - (50/1). The solution is Y*=1200 and r*=10. At these values for income and the interest rate, investment and consumption equal I*=100 and C*=950. Graphically, this is the point where the IS and LM curves intersect. policymakers, current theoretical models and current solution methods cannot be used to analyse the implications of gross portfolio holdings in any very systematic way. This is because it is difficult to solve portfolio choice problems within standard general equilibrium macroeconomic models with complex asset markets. To solve this basic problem, every society must answer these three basic questions: 1. What goods and services will be produced? For example, an economy must decide whether they should produce kitchen appliances or weapons, build and fix roads or buy textbooks for schools. 2. How will goods and services be produced? GDP is the total value added, or $1 + $2 + $3 = $6. Note that GDP equals the value of the final good (the bread). 3. When a woman marries her butler, GDP falls by the amount of the butler's salary. This happens because measured total income, and therefore measured GDP, falls by the amount of the butler's loss in salary. 1.2 Economic goods and free goods The vast majority of goods and services are economic goods. This means that it take s resources to produce them and so they are limited in supply. For example, a carpe t is an economic good. The material and labour used to produce it could have been used to make Chapter 1: The nature of the economic problem economic concepts and economic analysis to the problems of formulating rational managerial decisions. Spencer and Siegelman have defined the subject as "the integration of economic theory with business practice for the purpose of facilitating decision making and forward planning by management." Micro, Macro, and Managerial Economics Problem Set 4 -- Suggested Answers I. Measurement of Price Changes. In Merryland, there are only 3 goods: popcorn, movie shows, and diet drinks. The following table shows the prices and quantities produced of these goods in 1980, 1990, and 1991: 1980 1990 1991 P Q P Q P Q Popcorn 1.00 500 1.00 600 1.05 590 Movie Shows 5.00 300 10.00 200 10.50 210 Thus, the definition of the market is characterized by the idea of economic space, that is, it is not confined to a specific region that is to say that there is no physical or geographical limitation. 2- Negotiations are voluntary and the price system functions as a common denominator in trade. 3- There is no need for the explicit presence of 1.
