## 经济代写|国际经济学代写International Economics代考|Many Commodity Extension

When the home and foreign countries produce many goods, the pattern of trade between them is still determined by the relative labour ratios but now in relation to the ratio of wages of the two countries. Suppose pre-trade each country produces the same set of $n$ number of goods. These goods are indexed in a way that labour requirement at home relative to that in the foreign country is larger for successively higher indexed good:
$$\frac{a_{L 1}}{a_{L 1}^}<\frac{a_{L 2}}{a_{L 2}^}<\ldots . .<\frac{a_{L n}}{a_{L n}^}$$ Note that for any pair of goods the home country has a comparative cost advantage in a relatively lower ranked good: $$\frac{a_L}{a_L^}<\frac{a_{L j}}{a_{L j}^} \Rightarrow \frac{a_L}{a_{L j}}<\frac{a_L^}{a_{L j}^} \quad \forall i}<\frac{a_{L 2}}{a_{L 2}^}<\ldots \frac{a_{L i}}{a_{L i}^} \leq \frac{w^}{w}<\frac{a_{L j}}{a_{L j}^}<. .<\frac{a_{L n}}{a_{L n}^}$$ In case of weak inequality, the home country can produce the $i$-th good at the same or lower cost than the foreign country: $$a_L w \leq a_L^ w$$
Thus, given the diminishing home country comparative cost advantage pattern defined in equation (5.11) or in equation (5.13), through competitive forces and arbitrage all goods indexed lower than $i$ will be produced only in the home country and all goods indexed higher than $i$ will be produced only in the foreign country. In case of strict inequality in equation (5.14) and in equation (5.13), good $i$ will also be produced only in the home country. In such a case, all goods $1,2, \ldots i$ will be exported by the home country, and goods $j, \ldots, n$ will be exported by the foreign country. Thus, the Ricardian post-trade complete specialization result holds. But if good $i$ is equally costly in both the countries, this good will be produced by both and the countries will be incompletely specialized. The domestic demand patterns will then determine which country will export this good $i$.

Like the many commodities but two countries model, the Ricardian conclusions mostly carry over to the case of many countries but two commodities. A convenient way to discuss how the Ricardian conclusion generalizes to the case of trade among many countries is through the construction of the world production possibility frontier (PPF). To simplify matters, begin with the construction of world PPF in the case of two countries and two commodities. Consider the pattern of comparative cost advantage depicted in Figure 5.2. For given labour endowments and production technologies for the home and foreign countries, the maximum world production of textiles equals $O N_W=O N+O N^$. Such a maximum potential level of world textile production is attained for all relative prices of textiles that are larger than pre-trade prices in both countries so that both completely specialize in textiles. In Figure 5.6, this will be the case for all post-trade price lines steeper than $M^ N^*$. For a lower world relative price of textiles that equals the pre-trade price ratio in the foreign country, but is still larger than that in the home country, the home country is still completely specialized in textiles producing $O N$ amount, but for the foreign country the production of textiles can be any amount over the range $\left[0, N^{+}\right]$ depending on its domestic demand condition. Thus, for such a TOT, the world production of textiles can at the most be $O N_W$ and at the least be $O N$ when the foreign country specializes in computers. This gives us the linear stretch $R N_W$ of the world PPF.

For the world relative price of textiles smaller than the pre-trade price ratio in the foreign country but larger than that in the home country, as reflected by all price lines flatter than $M^* N^*$ but steeper than $M N$, the home country remains completely specialized in textiles whereas the foreign country now completely specializes in computers. The world production combination is thus $R$, which is known as the Ricardo point. For an even lower relative price equal to the pre-trade price ratio in the home country, the foreign country produces only computers but the home country may produce any combination of computers and textiles leading to the $R M_w$ linear stretch of the world PPF. Finally, for all world relative prices smaller than the pre-trade price ratio at home, both the countries completely specialize in computers and the world as a whole produces the maximum feasible units of computers, $O M_W=O M+O M^*$. Thus the twocountry world PPF is given by the kinked curve $M_W R N_W$.
