This work deals with econometric modeling of bilateral trade flows based on gravity model. Standard approach in most of previous empirical researches consisted of estimating bilateral trade potentials using gravity model and analysis of differences between the observed and predicted (potential) trade flows. Large differences were interpreted as the unexhausted foreign trade potentials. This work considers some limitations and problems of such approach mostly based on cross-section data. We consider alternative gravity model specifications with panel data and estimating procedures, as appropriate base for more precise estimates and conclusions. Furthermore, both theoretical and empirical analysis of econometric problems in panel data gravity model are carried out. Some of those problems have considered partially in previous empirical researches (for example autocorrelation in panels), but some of them have not considered at all, such as double endogenous regressors. Empirical results show that mentioned problems cause biased regression parameters estimates and consequently systematic variations of gravity model residuals (large systematic differences between observed and predicted). This makes conclusions on trade potentials between countries imprecise and unreliable.

Bilateral Trade Flows

This study analyzes the impacts of the formation of AFTA (ASEAN Free Trade Agreement) on China’s agricultural exports. The Hausman-Taylor analysis is applied to panel data collected from China and its 68 trading partners from 1993–2012. Our major findings areas follows. First, the discrimination in tariffs imposed by AFTA diverts trade in agricultural products from China toward AFTA’s member countries. Second, at the sectoral level, the trade diversion effects of AFTA’s formation on China’s exports are significant in the case of beverage and tobacco industries. AFTA and China need to focus more on diversifying and differentiating their farming products. To gain better access to AFTA’s market, more investment in research and development activities is recommended as a cure for Chinese farmers. Moreover, this study implies that more efforts in reducing tariff and non-tariff barriers to further liberalize trade between China and AFTA could enhance their bilateral trade flows.

AbstractThis paper quantifies the effect of GMO regulation on bilateral trade flows of agricultural products. We develop a composite index of GMO regulations and using a gravity model we show that bilateral differences in GMO regulation negatively affect trade flows. This effect is especially driven by labeling, approval process, and traceability. Our results are robust to the endogeneity of GMO standards to trade flows.

Bilateral Trade Flows

This paper examines the prospects of expanding bilateral trade between Pakistan and China particularly in the context of the recently signed free trade agreement between the two countries. Using the augmented gravity model in the tradition of Rose (2004), the paper shows that there is significant potential for the expansion of bilateral trade between the two countries as a result of the free trade agreement. The paper also analyzes bilateral trade flows between the two countries in terms of a trade specialization index and the Grubel-Lloyd index of intra-industry trade. We show that bilateral trade between the two countries is heavily tilted in favor of China and that this situation may persist in the short term.

Bilateral Trade Flows

As cryptocurrencies develop and circulate at greater rates, countries have appeared to consider the technology as an adoptable medium of exchange. By expanding the influence of cryptocurrencies through adoption, countries raise its impact on the global economy. This paper is the first to apply an augmented version of the gravity model to examine the effects of global cryptocurrency adoption on international trade. This empirical study involves aggregating datasets on U.S. bilateral trade flows, gravity variable statistics, and the adoption of cryptocurrencies. In application of the gravity model, regression analyses are used on the aggregated data to test the magnitude of cryptocurrencies’ impact on trade. Based on the overall findings, the variables for cryptocurrency adoption produce negative coefficients suggesting a negative correlation between the adoption of cryptocurrencies and international trade. The central tendency in the empirical evidence offers the interpretation that countries with weak institutions to promote trade are more likely to adopt cryptocurrencies resulting in a negative association between cryptocurrency adoption and trade.
