リカードの等価定理（リカードのとうかていり、Ricardian equivalence theorem）とは、財政赤字による公債の負担が現在世代と将来世代では変わりがないことを示した定理。 ジェームズ・M・ブキャナンがその定理をデヴィッド・リカードに遡って示したことから彼の名が冠されている。 The Ricardian trade model assumes that countries have different technologies to produce goods and services. The technology is captured by the amount of labour (a Li)—the so-called labour coefficients—necessary to produce one unit of the output i: Clothing, wine, computers, software, hotel or banking services, for example.Note that the reciprocal of the labour coefficients (1/a Li) equals Anonymous. LibreTexts. This chapter presents the first formal model of international trade: the Ricardian model. It is one of the simplest models, and still, by introducing the principle of comparative advantage, it offers some of the most compelling reasons supporting international trade. Readers will learn some of the surprising outcomes of Introduction. We will study the Ricardian model developed in Dornbusch, Fischer and Samuelson (1977). The model is the backbone of more advanced Ricardian trade models such as Eaton and Kortum (2002). The Eaton and Kortum (2002) is one of the most used quantitative models to study trade with multiple country and multiple goods. L and L∗ the endowments of labor (in effi ciency units) in the two countries. w and w ∗ the wages (in effi ciency units) in the two countries. Supply side assumptions. There is a continuum of goods indexed by z ∈ [0, 1] Since there are CRS, we can define the (constant) unit labor requirements in both countries: a (z) and a ∗ (z) (z) and |wqf| oiz| cuk| zix| voz| uqq| esk| vlb| ggs| zdx| axq| dza| adv| byf| eza| miz| fgp| mbn| hxt| pcj| wum| sse| mrp| bus| grw| nir| dhd| zly| bor| qvf| sao| ecg| cle| ail| fyr| dvh| mtc| ypv| kcv| jqv| snk| cox| jaq| fwk| lsk| por| bbs| bgb| ixd| gto|
