An Analysis on compositional effect during the great trade collapse
(2014) Bağırgan, Onursal
This thesis focuses on one of the famous hypotheses on The Great Trade Collapse which is compositional effect hypothesis. It includes three different parts. The first part examines the method of Levchenko, Lewis, Tesar (2010) for testing compositional effect, attempts to reproduce the results and conducts some robustness analysis of their results. The second part suggests some modifications on the existing model and applies the newly modified model to the US data. The findings suggest that compositional effect is an important factor of the US trade collapse during the The Great Recession. In the last part, the new model is applied to Turkey and the findings show that the compositional effect is not a significant factor of the trade reduction in Turkey. This result could be an indicator which shows that trade of the emerging countries are not governed by the same factors that drive developed country trade falls during the recent economic crisis.

The impact of environmental efficiency on bilateral trade : a panel data estimation of gravity model
(2009) Meyveci, Seda
In this study the role of environmental efficiency in the determination of bilateral trade flows is empirically examined by using Gravity Model for a panel data for 1971 to 2003. Although there are a number of empirical studies that analyze the relationship between environment and trade, most of them show insignificant relationship between environmental regulations and trade. Their differences are mostly due to the use of stringency indicators that are computed with different methods. This study, unlike previous studies, computes the environmental efficiency as a hyperbolic measure of technical efficiency in a non-parametric piecewise linear technology, with a production plan that maximizes the desirable outputs while simultaneously minimizing the resource use and pollution emission. The relationship between bilateral exports and environmental conditions measured as environmental efficiency index is investigated. The empirical results indicate that although there is no significant relationship between exports of a country and its own environmental efficiency index, there is a strong and robust positive effect of the partner country's environmental efficiency index.

New trade models with different distributions
(2013) İkizler, Hüsniye Burçin
In this thesis, we estimate the Ricardian trade model of Eaton and Kortum (2002) using a different extreme value distribution for the productivity distributions of countries. Due to its analytical convenience, it is now a common tradition in international trade literature to assume that the distribution of productivities follows a Fr´echet distribution, which is the case for Eaton and Kortum (2002) model as well. However, recent studies have shown that the estimation results are sensitive to this parametrization. In view of this, we estimate the Eaton and Kortum (2002) model where Weibull distribution is used for the distribution of productivities and show that estimated results change when we use another distribution.
