Estimating the gravity model when zero trade flows are frequent and economically determined (English)

This paper evaluates the performance of alternative estimators of the gravity equation when zero trade flows result from economically-based data-generating processes with heteroscedastic residuals and potentially-omitted variables. ... See More +

Methodology to carry out technical and biological rehabilitations in areas damaged due to mining activities (Vol. 2) : Main report (Mongolian)

In recent years, due to the rapid development of mining industry and intensive minerals exploration, exploitation and processing activities in the country, close to 300 million square meters of earth have been damaged including 1721.9 hectares as result of minerals extractions, 14565.0 hectares because of roads and communications infrastructure, and 1206.4 hectares due to construction works respectively, disfiguring massively the pristine natural landscape, reducing the river water levels due to many dried up rivers and streams, and ultimately causing overwhelming damage to the nature and environment. ... See More +
