(B)If the last dollar spent on product X will generate a higher marginal utility than that of spent on product Y, then you should increase the consumption of product X. (C)The price elasticity of demand for a product sill be more inelastic if spending on this product is in a very small proportion of the household’s budget. (D)When demand is elastic, the total revenue is directly related to output. (E)None of the above.
2. Which one of the following answers is right (A)A supply curve with larger slope will have smaller elasticity. (B)In order to have higher tax products with higher elasticity of demand. (C)When the price of the giffen foods increases, other things constant, its quantities demanded will decrease. (D)Luxury goods are usually goods with positive price elasticity. (E)Negative cross-price elasticity of demand indicates that two products are complements.
3. Which one of the following answers is right (A)The production possibilities frontier reflects the maximum possible combinations of two resources produced during a given time period. (B)The economic model of production possibilities frontier is based on simplifying assumption, but is still useful for illustrating scarcity, opportunity cost, and economic growth. (C)The straight-line PPF reflects that the resources are imperfectly adaptable. (D)The typical concave shape of PPF represents the law of decreasing opportunity cost. (E)None of the above.
4. Which one of the following answers is right? (A)The law of diminishing marginal returns results in that the slope of total cost becomes steeper in the short-run as more is produced. (B)As output increases, diseconomies of scale lead to rising short-run average total costs. (C)The expansion path shows the least-cost input combinations for producing each level of output, if input prices are constant. (D)At the point of tangency between an isoquant and an isocost line, the society is maximizing the social value of output, given its resources and technology. (E)If a monopolist engages in price discrimination, the marginal revenue curve is exactly the same as the firms’ demand curve.
5. If the demand curve of product X is :Dx = 38-4Px ,and is supply curve is : Sx = 5+6Px. If government imposes$1 indirect sales tax, the consumer and producer individually needs to pay (A)$0.4, $0.6 (B) $0.6, $0.4 (C) $0.75, $0.25 (D) $0.2, $0.8 (E)None of the above.
6. Which of the following answers is right (A)Firms in monopolistic competition use product differentiation to increase the price elasticity of demand. (B)The demand curve face by a monopolistically competitive firm is less elastic than the demand curve faced by a monopolist, but is more elastic than the demand curve faced by a perfect-competitive firm. (C)The kinked demand curve model describes an oligopoly where competitors match price decrease, but not price increases. (D)A profit-maximizing firm in monopolistic competition industry should shut down in the short run if prices are less than average fixed costs. (E)The monopoly firms could raise price to as much high as possible in order to maximize profits.
7. Which one of the following answers is right? (A)The values of inventories should be included in the accounting of GDP. (B)The demand-side economics in 1980’s focuses on increasing after-tax earnings by cutting tax and thereby providing resource owners with incentives to increase their provision of labor or resources. (C)Full employment means no frictional unemployment. (D)The U.S. trade deficit results in that Japanese owns many financial and real-estate assets in U.S. (E)None of the above.
8. Which of the following is wrong? (A)Keynes believed that wages and prices are relatively sticky because of contract agreement and labor union. (B)At lower price levels, consumption increases. (C)Consumption is mainly a function of the level of disposable income. (D)In the sticky wage model, the nominal wage has has fewer flexibility of going downward. (E)The classical economist believed in the self-correcting mechanisms, including price level and government assistance.
9. Which of the following is right? (A)If the short-run equilibrium level of GDP is less than the long-run equilibrium level, them as the economy approaches the long run, the price level will increase and output will decrease. (B)Assume that there are no excess reserves in the banking system. When the required reserve ratio is 20%, an individual’s purchase of $100,000 in U.S. government bonds from another individual can increase the money supply of $50,000. (C)If an initial increase in excess reserves of $1,000 can generate a maximum increase in the money supply of $4,000, the required reserve ratio must be 40% (D)An increase in the minimum wage would shift the aggregate supply curve inward. (E)Fiat money is redeemable for gold or silver.
