Bovine tuberculosis (bTB) in cattle has caused significant economic losses to livestock producers and has proven difficult to eradicate. It is suspected that cattle movement across different farms and regions is one of the key factors of bTB transmission in the United States. Prior attempts to model the epidemiology of bTB infection within cattle to predict disease transmission have not adequately captured the behavioral aspects of trade. A better understanding of livestock trade patterns would help in predicting disease transmission and the associated economic effects. In this paper, we develop a gravity model of livestock trade and link it to an epidemiological model of bTB transmission, with the goal being that this information could lead to improved... |

Given that in Brazil there is a significant asymmetry in production and trade among states, this study had as objective to measure the border effect to the intranational and international trade, using it as an indicator of the degree of integration. Such effect measures the bias to the internal trade of a country or state, in comparison to the external trade. A gravity model, including different dummy variables was used as methodology for this study. Results showed that intra-state trade in Brazil was 32 and 96 times larger than interstate and international trade, respectively. Interstate trade, was shown to be around 34 times larger than international trade. The border effect calculated to each state trading to other states, and to the rest of the world,... |

The paper analyses the effects of communication costs for agro-food trade in OECD countries between 1995 and 2003 using gravity model. We find that the link between the communication costs and agro-food trade flows in developed countries is significantly stronger for agricultural than for food products. The improved communication services reduce trade transaction costs. The estimations also confirmed importance of the economy size, level of development in importer countries, and trade distance. The other traditional gravity variables like contiguity, language and regional free trade agreements have significant impacts in the majority of specifications |

This study analyzes the impacts of cultural distance on bilateral trade flows in the Western Hemisphere using a Fixed Effects Vector Decomposition (FEVD). Four cultural dimensions of Hofstede are used to capture cultural distance. The results found that the effects of each dimension vary considerably with three of four dimensions (UAI, PDI, and MFI) have a negative impact and one dimension (ICI) has a positive effect. The magnitude of ICI is large enough to offset the negative effects of the other three dimensions resulting in a net positive effect of cultural distance, suggesting that culturally-dissimilar countries trade more than less. |

This paper addresses the question of whether Africa is an undertrading continent. We answer this question using a much-improved data set for obtaining predicted trade and by employing methods that correct for bias in estimates of undertrading. Our results indicate that globally Africa is an underexporter in our preferred Heckman specification. This result is robust to the addition of various controls and the application of variants of the gravity model of trade. We also looked for explanations for Africa’s undertrading. We found that accounting for transport and communication infrastructure reduced the undertrading effect for Africa, and in some specifications of the gravity model, the under-trading effect vanished altogether. Results from a semiparametric... |

Estimating the panel gravity model with bilateral pair and country-by-time fixed-effects separately for each seafood product, we found that food safety regulations have differential effects across seafood products. In all three industrialized markets, shrimp is most sensitive, while fish is the least sensitive to changing food safety policies. The enforcement of the US HACCP, the EU Minimum Required Performance Level and the Japanese Food Safety Basic Law caused a loss of 90.45%, 99.47%, and 99.97% to shrimp trade in these markets, and a reduction associated with fish trade was 66.71%, 82.83%, and 89.32%. |

The objective of this study has been to analyze the sensitivity of trade flow to trade barriers from gravity equations, using different econometric techniques recently highlighted in the literature. Specifically, we compare a benchmark OLS fixed effects specification a la Feenstra (2002), with three emerging estimation methods: the standard Heckman correction for selection bias, to account for zero trade flow; its extension, recently proposed by Helpman et al. (2008), to control for firm heterogeneity; and, finally, the Poisson pseudo-maximum-likelihood (PPML) technique to correct for the presence of heteroskedasticity, first proposed by Santos Silva and Tenreyro (2006). Our gravity model includes trade among 211 exporter and 104 importer countries, in 18... |

In view of the impacts on Chinese agro-products export caused by various technical barriers to trade, the academic circles analyzed it from the costs and quantity of exported agro-products. On the basis of the status quo of Chinese agro-products, the gravity model is introduced to analyze the impacts on Chinese agro-product export caused by technical barriers to trade. The results show that as long as the quality of Chinese agro-products can achieve the standard set by developed countries, for one thing, the health of Chinese consumers can be ensured, for another thing, the export of Chinese agro-products will be more smooth, which can provide reference for our government making decisions and solving trade dispute. |

In this study the case of olive oil imports of Germany is examined since olive oil is a traditional Mediterranean commodity and Germany is the biggest importer in the EU. A gravity model has been employed so as to analyse those factors that explain the German imports of olive oil that were identified in a preceding analysis of the German olive oil supply chain. The results of two random-effects models corrected for serial correlation and heteroskedasticity suggest that being a Mediterranean Partner country of the EU has the highest impact on trade flows to Germany, thus supporting further Euromediterranean trade integration. The level of trade to Germany is positively related to existence of direct marketing channels and to tourism implying that these... |

Globalization results when markets become more integrated because of reduced transaction and transport costs. These costs have fallen because of sustained advances in transport technology and, more dramatically, in digital information and communication technology (ICT). Although communication costs tend to be a minor component of total trading costs, reductions in these costs may strongly stimulate international trade. The empirical evidence in support of this effect is, however, scant and its strength may depend on the composition of ICT and the nature of the product being traded. We test the hypothesis of an ICT effect on trade in bananas, oranges, tomatoes, and vegetables and fruit in general. We employ a gravity model of international trade between... |
