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 study the intensity of joint hedging of oil and gas prices by US petroleum firms. We aim to explain the rationale for and find the determinants of joint hedging, as well as its impact on firm market value, performance, and riskiness. Joint hedging that takes into account the interdependence...

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...

In a seminal paper, Helpman et al. (2008) demonstrate that accounting for self-selection and firm heterogeneity is crucial for obtaining unbiased estimates in the gravity equation. In this paper, we show how this insight helps solve the trade elasticity puzzle that, hitherto, trade elasticity...

The small sample performance of system Generalized Method of Moments (GMM) and an alternative Transformed Maximum Likelihood (TML) estimator is investigated in Monte Carlo simulations, implementing a data generating process that tracks important features inherent in dynamic panels used in...

More than at any time in the history, climate change is having an increasingly unprecedented effect on human lives. Economies are affected severely in terms of sovereign risk due to climate change variations influencing the macroeconomy. Asian countries are highly susceptible to economic...

Statistical analysis provides a risk assessment of nuclear safety based on historical data. We use classical probabilistic models from risk theory to analyze data on nuclear power accidents from 1952 to 2011. Findings are that the severities of nuclear power accidents should be modeled with an...

The paper proposes a measure of countries' welfare based on individuals' lifetime utility and applies it to a large sample of countries in the period 1960-2000. Even though welfare inequality across countries appeared stable, the distribution dynamics points out the emergence of three clusters....
