The Ricardian model focuses only on differences in the productivity of labor across countries, and it explains gains from trade using the concept of comparative advantage. Ricardian Model of Trade Question 1 – Ricardian Model of Trade 15 marks (3+3+3+3+3) Suppose two economies Home (H) and Foreign (F) produce two goods, bread and wine , with only one production factor: labour . At world relative price p both countries specialize in their comparative advantage good. Ricardian Model Assumptions 1. The PPF equation is a linear equation—that is, it describes a line. The example demonstrates that both countries will gain from trade if they specialize in their comparative advantage good and trade some of it for the other good. (5 Points) (5 Points) This problem has been solved! A PPF is the combination of outputs of cheese and wine that the country can produce given a production technology (i.e., given that unit labor requirements are exogenous) and assuming all of its labor hours are employed. Labor is the only resource needed for production. Learn how the autarky terms of trade is determined in a Ricardian model. (3) 18th & 19th-century “Mercantilism” argued that power and wealth are associated with domestic production and exports. c.downward sloping in parts. ... • The production possibility frontier (PPF) of an economy shows the maximum amount of a good (say wine) that can be produced for any given amount of another (say cheese), and vice versa. A movement along the curve represents a transfer of labor resources out of one industry and into another such that all labor remains employed. Two goods: wine and cheese. An increase in world output given the same level of inputs is called an increase in world productive efficiency.

Canada’s PPF. endobj In fact, all production possibilities regardless of whether full employment is fulfilled are referred to as the production possibility set (PPS). 1 The Ricardian Trade Model The model is associated with David Ricardo (18 April 1772 to 11 September 1823), who was an English political economist. Labor is the only resource needed for production. • Q: What does mercantilism imply if we think in a global perspective? Comparison across countries based on unit labor coefficients Thus, the sale of goods and services generates revenue to the firms which in turn is used to pay for the factor services (wages to workers in this case) used in production. The Ricardian Model PPF Using the two production functions and the labor constraint we can describe the production possibility frontier (or PPF). In the Ricardian model, the PPF is a straight line. This model is a general equilibrium model, where flow of money in exchange for goods and services are in complete circle (supply equate to demand in all markets simultaneously). The Ricardian Model • A strong argument against the Mercantilism. When , both countries can consume outside its own PPF. stream Two countries: domestic and foreign. Note that MRT is the relative price of good 1 in autarky.

With some algebraic manipulation, we can rewrite the PPF equation into the standard form for an equation of a line, generally written as y = mx + b, where y is the variable on the vertical axis, x is the variable on the horizontal axis, m is the slope of the line, and b is the y-intercept.

Previous question Next question Transcribed Image Text from this Question. 55 Summary (cont.) One-Factor Ricardian Model. Ricardian Model of Trade. Since in the Ricardian model the PPF is linear, the opportunity cost is the same at all possible production points along the PPF. The PPF equation is a linear equation—that is, it describes a line. An increase in world output given the same level of inputs is called an increase in world productive efficiency. 17 0 obj The simplest way to demonstrate that countries can gain from trade in the Ricardian model is by use of a numerical example. -PPF is bowed out or concave (unlike Ricardian model) due to the output of 2 industries Manufac. Recall the … • China’s PPF has a much steeper slope than the U.S., indicating that the opportunity cost of a computer is much higher in China. Points inside the PPF are production possibilities but correspond to underemployment of labor resources. This is how Ricardo presented his argument originally. We begin by redrawing the production functions for manuf actures and food. 6 0 obj If prices of a nation's exported products rise in comparison to prices paid for imports, that nation experiences a: 5. Because the PPF is a straight line in the Ricardian model, Foreign's import demand curve is: a.upward sloping in parts. Using the two production functions and the labor constraint, we can describe the production possibility frontier (PPF)The set of all output combinations that could be produced in a country when all the labor inputs are fully employed. Japan’s PPF. 3. At world relative price p both countries specialize in their comparative advantage good. Two goods: wine and cheese. Ricardian Model Assumptions 1.
