Although economists have long been aware of Jensen's inequality, many econometric applications have neglected an important implication of it: the standard practice of interpreting the parameters of log-linearized models estimated by ordinary least squares as elasticities can be highly misleading...

Factor structures or interactive effects are convenient devices to incorporate latent variables in panel data models. We consider fixed effect estimation of nonlinear panel single-index models with factor structures in the unobservables, which include logit, probit, ordered probit and Poisson...

The Generalized System of Preferences (GSP) was established to promote the exports of low-income countries to industrialized countries in order to support their economic growth and development. However, the design of these schemes is rather complex and the effects of GSP have been found to be...

The paper applies the gravity model of international trade in its analysis of German exports. The added value of our research is derived from the innovative shift in focus from the traditional gravity model specifications to the national level in order to interpret its estimations in a...

The results generally confirm that Czech trade is oriented towards European countries and determined primarily by key economic factors of domestic and foreign GDP. The institutional variables remain largely insignificant, except corruption due tothe counterintuitive result that a higher...

The purpose of this paper is to examine Austrian foreign trade and estimate the country's export function. The analysis is based on the gravity model of trade in the log-log form, augmented by additional variables in order to control for the impact of institutions on decision-making. Our panel...

This paper investigates the role of Regional Trade Agreements (RTAs) on bilateral international migration. By increasing the information on the potential destination country, RTAs may favour bilateral migration flows among member countries. Building on the gravity model for migration by Anderson...

Existing gravity models of trade based on panel data are often static, that is, they only allow for contemporaneous effects of regressors on trade. However, there are numerous economic arguments suggesting that trade is a dynamic process. Hence, we extend the static model by including lags of...

We nest an extended two-way fixed effect (ETWFE) estimator for staggered difference-in-differences within the structural gravity model. To test the ETWFE, we estimate the effects of regional trade agreements (RTAs). The results suggest that RTA estimates in the current gravity literature may be...
