The gravity model specification for modeling international trade flows and free trade agreement effects: a 10-year review of empirical studies

Kepaptsoglou, Konstantinos; Karlaftis, Matthew G.; … - In: The Open Economics Journal 3 (2010), pp. 1-13

The gravity model has been extensively used in international trade research for the last 40 years because of its considerable empirical robustness and explanatory power. Since their introduction in the 1960's, gravity models have been used for assessing trade policy implications and,...

Modelling The Trade Flows of The Gulf Cooperation Council Countries: A New Approach to Gravity Model

Insel, Aysu; Tekçe, Mehmet Mahmut - 2009

This study analyzes the trade flows of the Gulf Cooperation Council (GCC) both among its member countries and with the rest of the world by employing a panel data gravity model in the context of the single country approach in order to capture the impacts of observable and unobservable variables...

The governance impact on the Romanian trade flows: An augmented gravity model

Tamaș, Anca; Miron, Dumitru - In: Amfiteatru Economic Journal 23 (2021) 56, pp. 276-289

The aim of this paper is to assess the impact of the quality of the Romanian governance process on the trade with EU countries between 2007 and 2018 using an augmented gravity model. The panel data method was used in order to cope with heteroskedasticity. The sample covers 12 years and includes...

Reliability analysis of repairable systems using system dynamics modeling and simulation

Rao, M. Srinivasa; Naikan, V.N.A. - In: Journal of Industrial Engineering International 10 (2014), pp. 1-10

Repairable standby system's study and analysis is an important topic in reliability. Analytical techniques become very complicated and unrealistic especially for modern complex systems. There have been attempts in the literature to evolve more realistic techniques using simulation approach for...

Analyzing nutritional impacts of price and income related shocks in Malawi: Simulating household entitlements to food

Harttgen, Kenneth; Klasen, Stephan; Rischke, Ramona - 2015

The 2007/2008 food price crisis and the following global economic recession has (temporarily) increased the number of people to suffer from hunger. While the impacts can be measured with precision only ex post, for policy makers it is critical to get a sense of likely impacts ex ante in order to...
