•• Third, the gravity model represents a realistic general equilibrium environment that GRAVITY MODEL ANALYSIS 49 principal resistance factors to trade, according to the gravity model, are being a landlocked country or a member of a country pair with a common colonizer (e.g., India and Kenya, both former UK colonies). 0000000711 00000 n <<2714F50D52CBA04880229E1F7C53B3A1>]>> 0000003974 00000 n range of trade theories.2 In particular, Bergstrand (1985 and 1989) shows that a gravity model is a direct implication of a model of trade based on monopolistic competition developed by Paul Krugman (1980). Two countries: home and foreign. Add 1 and then take logs. [Notice: gravity needs a minimal set of assumptions to hold.

Standard Data transformation Check all data are in the same unit of measure Log- transformation GDP deflation Zero trade: 2 ways to treat them 1. Pooling such demand equations across pairs or regional units or even across cross-sectional units and time inevitably leads to a panel data structure of the data. 0000008804 00000 n 538 0 obj <> endobj Looks like you’ve clipped this slide to already.

The gravity model of international trade in international economics, similar to other gravity models in social science, predicts bilateral trade flows based on the economic sizes (often using GDP measurements) and distance between two units. Furthermore, Gravity is arranged in such a way that it can be easily merged with any matrix of bilateral flows (trade, FDI, migrations, or other types of bilateral flows), using standard ISO codes for countries and for any year between 1948 and 2015. %PDF-1.4 %���� Each has met various aspects of what exactly you are looking for in a location.

The gravity model in economics was until relatively recently an intellectual orphan, unconnected to the rich family of economic theory. The gravity equation in international trade is one of the most robust empirical finding in economics: bilateral trade between two countries is proportional to size, measured by GDP, and inversely proportional to the geographic distance between them. Rongxing Guo, in China's Spatial (Dis)integration, 2015. 0000002451 00000 n The impact of the distance and other trade barriers are also identified in the model. 0000003454 00000 n View Notes - Trade Notes_PPT 2_Volume of Trade & Grav Model.pdf from ECON 542 at Georgetown University. This property makes the gravity framework particularly appropriate for counterfactual analysis, such as quantifying the effects of trade policy. The Gravity Model of International Trade holds that the amount of trade between two economies depends (largely) on two things: the size of the economies and the distance between them. 0000009204 00000 n 0000001876 00000 n According to the model, economic sizes and distance between nations are the primary factors that determine the pattern of international trade.
