Latin American Agri-Food Exports, 1994-2019: A Gravity Model Approach
Mathematics, 2022
This study analyses the causes of the strong growth in the agri-food exports of Latin America between 1994 and 2019. To do this, a series of gravity models are estimated, using as a dependent variable the agri-food exports of 15 Latin American countries to their 185 principal trading partners. The empirical specification is based on the gravity theory of trade, according to which, trade between two countries is determined by the size of both of their markets and their transport costs. Other variables have also been included, considering the theoretical foundations proposed for the gravity model. We initially used the PPML estimator since it is the method that provides estimates with the best properties. We later compared these results with those obtained through OLS and the Heckman selection model. Our findings show that the growth in agri-food exports is explained by factors of both supply and demand, but that the latter plays a more important role since we have obtained evidence of a reverse home-market effect. Furthermore, we can conclude that the creation of regional trade agreements, such as NAFTA, MERCOSUR, CACM, APEC, and TPP, has significantly favoured agri-food exports in the region.
Employing Gravity Model to Measure International Trade Potential
9th Annual Basic Science International Conference 2019 (BaSIC 2019), 2019
Starting from the analogy of gravitational forces to explain the volume of bilateral trade, the Gravity model has become a very popular model in international trade research. The Gravity Model has also been widely developed by adding various independent variables. Instead to measuring trading volume and various factors that influence the volume of trade, there is not much utilization of the gravity model to measure trade potential. This research is intended to implement a gravity model to measure the potential of Indonesian fruit trade. The measurement of trade potential is carried out by using data on the three main group of Indonesian exported fruits (based on 6 digits HS Code) which traded in 16 years. The classical gravity model, employed in this research contains independent variables, such as the amount of tariffs, the existence of free trade agreements, population, GNP of each country, distance and share of trade. The method of analysis used refers to the gravity model applied by Susanto, et al (2007) and regression analysis method applied by Arita et al (2014). Since its easily fits with some important stylized facts, it is easy to use real data, and also easily estimates using Ordinary Least Square (OLS), the Gravity Model can be a comprehensive instrument for managing big data to present rapid and dynamic estimates of international trade in line with the demands of the Revolution Industry 4.0.
THE GRAVITY MODEL OF TRADE: A THEORETICAL PERSPECTIVE
Review of Innovation and Competitiveness: A Journal of Economic and Social Research, 2019
Purpose. The purpose of this study is to trace the theoretical developments of the gravity model of trade. The key question is: what are the dominant features of the development of the gravity trade model? Methodology. This research is conducted by employing a number of methods that include the historical, descriptive and analytical methods. The main contribution of this paper is to trace the historical and theoretical development phases of the gravity model. Findings. This study is a novel attempt in terms of the identification of the four distinctive phases of the development of the gravity model. This work would, therefore, expand the existing literature on the gravity model. We argue that the development of the gravity model is the outcome of many research efforts. A large body of literature has given the model a solid theoretical foundation. But there is no consensus about the proper econometric estimation methods of the model. The gravity model is significant both historically and analytically.It is a useful tool for the analysis of international trade. It has become a popular research device used by the researchers and policy makers around the world. The gravity is regarded as one of the most successful models in the literature of international economics. Originality. The original contributions of this paper lie in streamlining the consistent historical development of the gravity model over a longer period of time-frame, ranging from 1885 to 2018. Limitations and Implications. This work is theoretical aspects of the trade gravity model. Future researchers could overcome the limitations by combining the theoretical and empirical studies in a paper. This paper can help the future researchers in dealing with the broad body of literature of gravity model
Chapter 4 The Gravity Model in International Trade
2011
Since Jan Tinberben’s original formulation (Tinbergen 1962, Shaping the World Economy, The Twentieth Century Fund, New York), the empirical analysis of bilateral trade flows through the estimation of a gravity equation has gone a long way. It has acquired a solid reputation of good fitting; it gained respected micro foundations that allowed it to move to a mature stage in which the “turn-over” gravity equation has been replaced by a gravity model; and it has dominated the literature on trade policy evaluation. In this chapter we show how some of the issues raised by Tinbergen have been the step stones of a 50-year long research agenda, and how the numerous empirical and theoretical contributions that followed dealt with old problems and highlighted new ones. Some future promising research issues are finally indicated.
The Gravity Equation in International Trade
Oxford Handbooks Online, 2009
This chapter offers a selective survey of the gravity equation (GE) in international trade. This equation started in the Sixties as a purely empirical proposition to explain bilateral trade flows, without little or no theoretical underpinnings. At the end of the Seventies, the GE was "legitimized" by a series of theoretical articles that demonstrated that the basic GE form was consistent with various models of trade flows. Empirical applications of GE expanded to cover a variety of issues, such as the impact of regional trade agreements, national borders and currency unions on trade, as well as the use of the equation to sort out the relative merit of alternative trade theories. A new wave of studies is now concentrating on the general equilibrium properties of the GE and finer econometrics points. The renewed interest of the academic profession in the development of the GE is undoubtedly driven by the equation's empirical success.
A Critique of the Gravitational Model in Estimating the Determinants of Trade Flows
Research pertaining to variables that are capable of influencing trade flows has undergone a different econometric evolution if compared to other macroeconomic variables. The analysis of economic literature in this field, especially in reference to a technical approach (i.e. utilizing a co-integration or a VAR approach), has rather focused on a systemic study. In this context, the gravitational model has revolutionized the econometric process of analysis of the determinants of trade flows, highlighting numerous improvements. However, although this model is capable of also explaining international trade between economies of scale, it has always (in an econometric perspective) automatically accepted the value of the intercept as the result of the difference between Y-ß1X1. This paper, after having defined the variables that are capable of influencing trade flows, will suggest a different method of econometric calculation of the gravitational model.
Augmented gravity model: An empirical application to Mercosur-European Union trade flows
Journal of applied …, 2003
This paper applies the gravity trade model to assess Mercosur-European Union trade, and trade potential following the agreements reached recently between both trade blocs. The model is tested for a sample of 20 countries, the four formal members of Mercosur plus Chile and the fifteen members of the European Union. A panel data analysis is used to disentangle the time invariant country-specific effects and to capture the relationships between the relevant variables over time. We find that the fixed effect model is to be preferred to the random effects gravity model. Furthermore, a number of variables, namely, infrastructure, income differences and exchange rates added to the standard gravity equation, are found to be important determinants of bilateral trade flows.

A gravity model of trade for Nicaraguan agricultural exports
This research aims to find the determining factors of Nicaraguan agricultural exports. To carry out this study, the author formulated a Gravity Model of Trade (GMT) and then made an estimation using a version of Ordinary Least Squares (OLS) that incorporates a consistent covariance matrix estimator to correct the heteroskedasticity and autocorrelation effects. The data considered observations over twenty years and for twelve countries: eight have signed a Free Trade Agreement (FTA) with Nicaragua and four have not. The variables that significantly increased the flow of Nicaraguan agricultural exports are the following: Nicaragua’s trading partners’ population, Nicaragua’s Gross Domestic Product per capita (GDP pc), the Real Exchange Rate (RER), and Nicaragua’s trading partners’ GDP pc; however, the distance variable turned out to be significantly trade-inhibiting. Free Trade Agreements (FTAs) predominantly have significant effects.
