2.3 Armington model and its results In this sub-section, we present a brief overview of the Armington model that has been used by other researchers to find the relationship between exchange rate volatility and trade. In some trade models, such as neo-classical trade models, we assume that goods are homogeneous even though they are produced in different countries. Indeed, the prices of goods produced in different countries do not move in the same direction. However, it was first pointed out by Armington (1969) that goods that are produced in different countries need to be treated differently. An overview of Armington (1969) is that the change in demand for goods depends on the growth of the market in which firms compete and the growth of …show more content…

The second paper is that of Peridy (2003) which uses the Armington approach. The author finds that the impact of exchange rate volatility is misleading. The third paper using the Armington approach is that of Saito (2004), who uses the constant elasticity of substitution (CES) functional form of Sato (1967) and finds that Armington elasticities are higher for multilateral trade data than bilateral trade data. Lastly, there is the work of Byrne et al. (2006) which uses the Armington approach with similar utility function as in Saito (2004), finding that exchange rate uncertainty has a robust negative …show more content…

However, we found that rice is an inferior good in which an increase in income leads to lower consumption. The main idea behind the gravity model is that countries with larger economies tend to trade more, while distance represents a proxy for transportation costs and higher distance should lead to lower bilateral trade. Indeed, Ariccia (1999) found that exchange rate volatility has a negative impact on international trade. Another paper for consideration is Tenreyro (2004) which tests the effect of nominal exchange rate on trade by using the gravity model to explain the phenomenon. However, the author adds importer and exporter specific effects (s_i and s_j) to account for multilateral resistance and concludes that two countries that peg their currency to the same anchor experience a lower level of exchange rate fluctuation. Lastly, Aristotelous (2001) tests exchange rate volatility and trade volume by using the gravity model in the same context as Bergstrand (1989) with the dummy variable of w_t equal to one if world war one and zero if world war two and where D_1 is the managed float exchange rate regime dummy that is equal to one when a managed float regime is in effect. The author finds that exchange rate volatility has no effect on British
