Important information Dear Examinee, The examination consists of four parts. Part I contains multiple choice questions. In this part of the examination choose only the answer you think is the correct one. Unclear, or more than one answer will not be awarded points. Part II consists of true-false questions. Write either T (true) or F (false) next to the answer to indicate your choice. Attention, you have to explain your answers.(correct answers with an appropriate explanations: 1+1 point; correct answers with inappropriate explanations or no explanation: 1+0 points; incorrect answer: 0+0 points.) Part III requires you to write short answers to the questions. Your answers should be a maximum of three or four sentences! Part IV requires you to make calculations and solve geometry problems. We suggest that when you are preparing your graphs you use a pencil, however, your final answer must be written in pen. Use a ruler in order to create precise drawings! Providing answers to calculations is not enough, you must show the formula you use on the answer sheet. (Of course, we do not need you to show every trial calculations, or multiple possible answers, we only need you to show the steps leading to the final answer!) All parts may contain tasks in the fields of micro economics, macro economics and international economics. Pay close attention to the instructions! Try to provide an answer for each question asked! The points attainable are listed in each section. Partial scores are possible. Maximum points available for a perfect score is 90. Rulers and calculators may be used to solve the set tasks. If the space provided is not sufficient to solve the task you may ask the supervising staff for an official sheet, however, this must be indicated on the task sheet next to the question! Good luck! írásbeli vizsga 1011 2 / 12 2011. május 23.

PART II, TRUE-FALSE QUESTIONS, WITH EXPLANATIONS. Write either T (true) or F (false) next to the answer to indicate your choice. Attention, you have to explain your answers! Correct answers with an appropriate explanation: 1+1 point; corrects answer with inappropriate explanation or no explanation: 1+0 points; incorrect answers: 0+0 points.) (9 2 = 18 points) 1. If a consumer currently ties up his income in products x and y so that MU x /P x > MU y /P y, then his utility can increase if he increases consumption of product x to the detriment of product y. 2. The marginal utility of air is zero in the case of optimal consumption. 3. If Peter and Paul always consume a bottle of apple juice together at lunch, then for them the apple juice is common good. 4. If they produce 10 units of wheat or 5 units of rye in Hungary in a single work day and in Germany they can produce 16 units of wheat and 10 units of rye, then Hungary has a comparative advantage in wheat production over Germany. írásbeli vizsga 1011 5 / 12 2011. május 23.
5. If the government increases household taxes and transfers paid out to households at the same time and by the same amount then as a result consumption will increase. 6. If the labor force secures increases in nominal wages without increases in productivity then price levels rise because of this while equilibrium out decrease. 7. In a three player economy raising interest rates leads to a down turn in equilibrium revenue because government spending decreases. 8. In addition to domestic and foreign price level devaluation of domestic currency increase the export of goods and decreases the import of goods. 9. Over the short term a monopoly surely does not produce, if the market price related to the production quantity determined by the equilibrium of marginal revenue and marginal cost is smaller than the average cost related to the same production quantity. írásbeli vizsga 1011 6 / 12 2011. május 23.
PART III REQUIRES YOU TO WRITE SHORT ANSWERS TO THE QUESTIONS. Your answers should be a maximum of three or four sentences! (4 3 = 12 points) 1. Mike Magnet consumes only products x and y. We know that his current income and prevailing product prices the budget line equation y = 100 4x. Determine the maximum of y or x products that Mike can consume if he spends his income on only one or the other product, and provide the P x / P y ratio for the two product's prices! 2. Let's say, that a perfectly competitive firm generates significant economic profit at the low point of a short run average cost curve. Based on this information does the firm produce at profit maximization or should they increase or possibly even decrease production? Explain your answer! 3. In a two party economy consumers always spend 80% of the current real wages (autonomous consumption is zero). There are only supplementary investments and every year 10% of capital stock is exchanged. The long run equilibrium value of capital stock is K = 1000 units. Provide the equilibrium income and consumption value! 4. Define potential output! írásbeli vizsga 1011 7 / 12 2011. május 23.

2. Profit maximizing Golden Wrench Ltd assembles automotive engines for a large automobile maker. They receive the parts from the factory and they deliver the assembled engines to the factory. They receive a fixed price of 500 Euro for one assembled engine. The equation showing the correlation between Ltd. production and labor used, if other factors are given and unchanged is Q = 90L 4L 2. The marginal product-function equation for this is: MP L = 90 80L. Wages (labor cost per unit) at the Ltd is a given P L = 1 000 Euro. In addition to the above we know that that Ltd uses 100 000 Euro stock capital on rental fees, and property rent is 50 000 Euro. The company has no other costs. a) Provide the equation for the value of marginal product (VMP) curve. b) Determine how many units of labor the Ltd uses and how many engines are assembled. c) Determine the Ltd's profit. d) Let's say that the authorities are carrying out an on-site inspection of the Ltd and they determine that the Ltd's production process is polluting the environment. Therefore, they order that a certain percentage of the proceeds henceforth be paid as an environmental protection fee. Without calculations determine how the fee will affect how the amount of labor and output of the Ltd! 2 + 4 + 2 + 3 = 11 points írásbeli vizsga 1011 9 / 12 2011. május 23.
