By combining new data on bilateral asset holdings with data on securities regulation in an empirical gravity model, it is found that bilateral differences in securities regulation lead to decreased portfolio holdings. Hence, regulatory harmonization can foster financial integration. The results are especially strong for equity holdings. It is verified that the results do not just reflect genera...

This paper provides an original study into how democratization and globalization in‡uence transnational terrorism — examining the motives of terrorists and how democratic institutions and international integration in‡uence non-state economic actors. We employ a gravity model to investigate the relative importance of globalization and democratization on transnational terrorism and external con‡i...

This paper investigates the relationship between intra-industry trade (IIT) and immigration flows using a gravity model for the period 2000-2010 between Portugal and European Union’s Member States (EU-27). The present study uses the methodology of Kandogan (2003) for separating IIT into its components horizontal (HIIT) and vertical intra-industry trade (VIIT).Using a panel data approach, our st...

We consider solutions of the field equations for the large N dilaton gravity model in 1 + 1 dimensions of Callan, Giddings, Harvey, and Strominger (CGHS). We find time dependant solutions in the weak coupling region with finite mass and vanishing flux, as well as solutions with lie entirely in the Liouville region.

We show that a canonical transformation converts, up to a boundary term, a generic 2D dilaton gravity model into a bosonic string theory with a Minkowskian target space.

This study is an empirical attempt to find out whether under sanctions Iran’s trade direction has shifted away from Europe (trade policy of de-Europeanization) towards Asia (trade policy of Asianization). The analysis is conducted using a panel-gravity trade model to analyze bilateral trade pattern between Iran and 50 countries from the EU and Asia during the period 2006–2013. To this end, the ...

The aim of this empirical study is to explore the trade-off model and pecking order model of capital structure. The investigation is performed using panel data procedures for a sample of 76 firms listed in Tehran Stock Exchange during 2007-2010.The study employs OLS regression model in examining the capital structure of firms in Iran. The study employs variables reflecting differing theoretical...

We show how a Metric Affine theory of Dilaton gravity can be reduced to an effective Riemannian Dilaton gravity model. A simple generalization of the Obukhov-Tucker-Wang theorem to Dilaton gravity is then presented. 04.20.-q, 04.40.-b, 04.50.+h, 04.62.+v [email protected]

Drawing on a new and comprehensive measure of logistics quality, our gravity model suggests logistics in the exporting and partner-country can have an important impact on bilateral exports. A one standard deviation improvement in the exporter’s logistics quality, which for example would improve Gabon to the level of Guinea, would raise exports by almost 60%. Landlocked countries’ exports depend...
