| Fishing capacity management policies have been traditionally implemented at national level with national targets for capacity reduction. More recently, capacity management policies have increasingly targeted specific fisheries. French fisheries spatially vary along the French coastline and are associated to specific regions. Capacity management policies however ignore the capital mobility associated with second-hand vessel trade between regions. This is not an issue for national policies but could limit the effectiveness of regional capacity management policies. A gravity model and a random-effect Poisson regression model are used to analyse the determinants and spatial extent of the second-hand market in France. This study is based on panel data from the... |

| A tectonic model of the evolution of the northern half of the South Fiji Basin, including the Minerva Triple Junction and Cook Fracture Zone, is developed from regional gravity, multibeam bathymetry, and a new interpretation of magnetic anomalies pinned to radiometric dates of oceanic crust in the basin. The geometry and age of a portion of the Minerva Triple Junction and the Cook-Minerva spreading center (the connection from the triple junction to the Cook Fracture Zone, which accommodated coeval opening of the Norfolk Basin), are resolved with multibeam bathymetry and magnetics. The South Fiji Basin opened from about 34 to 15 Ma in an anticlockwise sweep about an Euler pole located at the northern end of the present Lau Ridge. This rotation and a rigidly... |

| 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... |

| 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... |

| This paper explores the effect of exchange rate volatility and of the institutional quality on international trade flows of transition economies in Central European Countries by applying a gravity model of balance panel between 1999 and 2008. The results show that nominal exchange rate volatility has had a significant negative effect on trade by applying Psuedo- Maximum-Likelihood (PML) estimator method over this period. The institutional quality need to be improved in case of size of government and the quality of regulation. The negative effect of exchange rate volatility on agricultural exports suggests that joining Central European Countries to the euro zone can reduce the negative effects of exchange rate volatility on trade. |

| A modified gravity-type model was employed to evaluate the effect of exchange rate volatility on wheat exports worldwide. Special attention was given to the econometric properties of the gravity model within panel framework. Short and long-term measures of exchange rate volatility were constructed and compared. Both measures of exchange rate volatility have exhibited a negative effect on world wheat trade and the long-term effect was even larger. This result implies that exchange rate volatility is an important factor in explaining the trade pattern of wheat trade worldwide. Keywords: wheat, export, exchange rate, volatility, gravity model, and panel data. |

| This study empirically investigates the effects of structural reforms on bilateral trade flows of agricultural products. Specifically, the study jointly analyzes the impacts of three different reforms including financial reform, trade reform, and agricultural reform on agricultural trade. The results suggest that less restrictive credit constraints, reduced tariff rates, and less government interventions are likely to generate increase in total agricultural exports. The evidence further indicates that the impacts of the reforms vary considerably across less aggregated products as well as across reform forms. The results provide a solid policy foundation for pursuing structural reforms in order to stimulate trade and economic growth, given the fact that the... |

| The paper investigates the effects of the institutional determinants on trade in agricultural and food products among the OECD countries using a gravity model approach. We focus on the impact of the quality of governance and the similarity of institutions in explaining variation in bilateral agricultural and food trade patterns. Results confirmed the separate effects for the institutional similarity and the institutional quality on trade patterns. The institutional similarity has positive and significant impact on trade in a similar institutional framework for agricultural, but less for food products. The institutional quality has significant positive impact on trade in both agricultural and food products for importing countries. |

| 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. |

| 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... |

| This paper examines whether exchange rate misalignment negatively affects agricultural trade, compared to other industry sectors. Nominal exchange rate misalignment is obtained from the percentage deviation of real exchange rates from their long-run equilibrium based on the theory of purchasing power parity. In order to explore this issue, a bilateral trade matrix involving trade flows between 10 developed countries is constructed. Using panel data analysis, a gravity model is estimated for 4 industry sectors over the period 1974-1999. The study finds that over-valuation (under-valuation) of the nominal exchange rate negatively (positively) affects export performance of the agricultural sector in particular. In the large-scale manufacturing sectors... |
