MCQ Economics Class 12 Chapter 4 The Theory of Firm Under Perfect Competition Microeconomics Advertisement MCQ’s For All Chapters – Microeconomics Class 12th 1. At the profit-maximising output, marginal cost should be: Decreasing Non-decreasing Constant at zero Equal to total costQuestion 1 of 202. In the short run, a firm can continue producing when the market price is: Less than AVC Greater than or equal to AVC Always less than AVC Equal to zero onlyQuestion 2 of 203. In the long run, a firm must have the market price: Greater than or equal to AC Less than AC Equal to AVC only Less than AVCQuestion 3 of 204. If the market price is below the minimum AVC in the short run, the firm will: Increase production Produce at maximum capacity Produce zero output Increase its price above the market priceQuestion 4 of 205. If the market price is below the minimum LRAC in the long run, the firm will: Continue producing indefinitely Produce zero output and exit Increase its output Reduce its fixed cost onlyQuestion 5 of 206. The short-run supply curve of a firm is the: Falling part of the SMC curve Rising part of the SMC curve from and above minimum AVC Entire AVC curve Entire SAC curveQuestion 6 of 207. The long-run supply curve of a firm is the: Rising part of LRMC from and above minimum LRAC Falling part of LRAC Entire LRAC curve Horizontal portion of AVCQuestion 7 of 208. The short-run shut-down point occurs at the: Maximum AVC Minimum AVC Maximum AC Minimum total costQuestion 8 of 209. In the long run, the shut-down point is determined by the: Minimum LRAC Maximum LRMC Minimum AVC Maximum total revenueQuestion 9 of 2010. The minimum level of profit needed to keep a firm in its existing business is called: Super-normal profit Marginal profit Normal profit Total profitQuestion 10 of 2011. Profit earned over and above normal profit is called: Fixed profit Super-normal profit Average profit Variable profitQuestion 11 of 2012. The point at which a firm earns only normal profit is called the: Shut-down point Supply point Break-even point Production pointQuestion 12 of 2013. Technological progress generally shifts a firm's supply curve: To the left To the right Downward only without affecting supply NowhereQuestion 13 of 2014. An increase in the price of an input generally shifts the firm's supply curve: To the right To the left Vertically upward only NowhereQuestion 14 of 2015. A unit tax is a tax imposed by the government: Per unit of output sold Only on total profit Only on fixed cost Per firm regardless of outputQuestion 15 of 2016. The imposition of a unit tax shifts a firm's long-run supply curve: To the right To the left To the origin only It has no effectQuestion 16 of 2017. The market supply curve is obtained by: Vertical summation of individual supply curves Horizontal summation of individual supply curves Subtracting individual supplies Multiplying individual suppliesQuestion 17 of 2018. If the number of firms in a market increases, the market supply curve shifts: To the left To the right Downward only It does not shiftQuestion 18 of 2019. Price elasticity of supply measures the responsiveness of: Price to changes in demand Quantity supplied to changes in price Cost to changes in output Revenue to changes in costQuestion 19 of 2020. When a straight-line supply curve passes through the origin, its price elasticity of supply is: Greater than 1 Less than 1 Equal to 1 Equal to 0Question 20 of 20 Loading...
