Richard slept through macroeconomics, so he suggests Dave do all the work since he’s faster at both anyway – typical Richard. \n\nBut Dave remembers what **David Ricardo**, the British economist, said about comparative advantage. Dave argues that, although he has an absolute advantage on both tasks – he’s faster at both – he’s constrained by time. Every minute washing cars is a minute not mowing lawns, and vice versa. Dave draws up a table showing the opportunity cost, which is how much he loses by not spending his time efficiently.\n\nTo wash a car, Dave gives up mowing 0.38 lawns (1.5 lawns for every 4 cars) versus Richard’s 0.5. Dave has comparative advantage, so he should wash cars. Meanwhile, Richard has comparative advantage over Dave at mowing lawns. He should do it because it only costs him 2 car washes when it costs Dave 2.67.\n\n ![Graph](image://9ef7c4fd-347a-4036-aae0-ab29d71fccc7 \"Comparative Advantage for Dave and Richard\")\n\n","b87801f4-3349-41a4-b64a-631ed48d0183",[35,47],{"id":36,"data":37,"type":38,"version":30,"maxContentLevel":19},"299f643a-f06d-49a8-9fe5-3e6051ca5e53",{"type":38,"reviewType":19,"spacingBehaviour":30,"multiChoiceQuestion":39,"multiChoiceCorrect":41,"multiChoiceIncorrect":43},11,[40],"Who developed the theory of comparative advantage?",[42],"David Ricardo",[44,45,46],"John Maynard Keynes","Robert Solow","Milton Friedman",{"id":48,"data":49,"type":38,"version":30,"maxContentLevel":19},"b52d4a22-f8c1-49fa-9b0e-4db90610c0b3",{"type":38,"reviewType":30,"spacingBehaviour":30,"activeRecallQuestion":50,"activeRecallAnswers":52},[51],"What is comparative advantage?",[53],"Comparative advantage is the theory that one person might be able to carry out a task more efficiently than another",{"id":55,"data":56,"type":30,"maxContentLevel":19,"version":30,"reviews":60},"2fd2fafb-6725-4816-b78d-9307e58122bb",{"type":30,"title":57,"contentRole":20,"markdownContent":58,"audioMediaId":59},"My wood for your sheep","The concept of **comparative advantage** explains why free trade is a good thing. Producing stuff costs. Besides the raw material and labor involved with manufacturing goods, there’s opportunity cost too – every time an economy decides to produce something, it gives up the opportunity to produce something else. Countries should specialize in goods and services where their opportunity cost is lower compared to other nations. \n\nLet’s look at strawberries and crude oil. South Korea exports the former, and Saudi Arabia the latter. If Saudi Arabia wants strawberries, it should just import from South Korea instead of struggling – and failing – to cultivate the fruit. Otherwise, it may end up diverting resources that will be more productive at extracting crude oil into an impossible task. By engaging in trade, both South Korea and Saudi Arabia benefit. They satisfy their wants and needs at minimal cost.\n\n**The benefits of trade apply to goods and services that aren’t impossible for an economy to produce**. The Philippines is heavily agricultural, but it also imports rice from countries with a comparative advantage in rice production. This provides the Philippine market with additional variety as well as cheaper options.\n","a5112b35-eea7-4ec4-96fd-0a6131cb3c53",[61],{"id":62,"data":63,"type":38,"version":30,"maxContentLevel":19},"af11e48f-35e5-4380-abf7-0793c5731258",{"type":38,"reviewType":64,"spacingBehaviour":30,"clozeQuestion":65,"clozeWords":67},4,[66],"In what is known as the opportunity cost, every time an economy decides to produce a good, it gives up the opportunity to produce another",[68],"opportunity cost",{"id":70,"data":71,"type":30,"maxContentLevel":19,"version":20,"reviews":75},"51dc57bd-fdef-4835-b510-1d4c56584bf0",{"type":30,"title":72,"contentRole":20,"markdownContent":73,"audioMediaId":74},"Use it to your (comparative) advantage","Where and how do economies gain comparative advantage in producing goods and services?

China’s large population makes it conducive to manufacturing, especially in labor-intensive industries. Meanwhile, India, with an equally large population, has a labor force fluent in English and trained in IT, hence why so many companies outsource remote customer service there. Western nations can rely on India’s fairly educated English-speaking population to provide support services like customer care and business processing.

Intra-industry trade, the trade of goods within the same industry, allows countries to achieve economies of scale. Producing at higher volumes lowers per-unit cost by spreading fixed costs like tools, equipment, and research across a larger production quantity. **This concept is known as ‘economies of scale.’**\n\nTo produce a chair, for example, you’d need a saw, some glue, and wood. Glue is sold by the pail, so making 1 chair leaves you half a pail of glue extra. What if you decided to produce 10 chairs? You’d have to buy 10 times as much wood and 5 times as many pails of glue, but the saw you have is enough to complete the job. This brings costs down somewhat. You waste half a pail of glue less, and you distribute the cost of 1 saw across 10 chairs.\n\nFinally, imagine producing 100 chairs. At that volume, you can negotiate with your supplier for bulk pricing to bring your per-unit cost of wood and glue down.
