This paper aims at the exploration of the questions connected with the effects of uncertainty and risk in agriculture and, generally, in each economic sector where risk considerations are established. The aim of the first part is to give the key features for the estimation of production structures using dual approach and risk prevalence. In order to state risk non-neutrality into the implemente...

BACKGROUND Infant mortality is an important measure of human development, related to the level of welfare of a society. In order to inform public policy, various studies have tried to identify the factors that influence, at an aggregated level, infant mortality. The objective of this paper is to analyze the regional pattern of infant mortality in Brazil, evaluating the effect of infrastructure,...

This paper proposes the GMM estimation of the spatial dynamic panel data model with …xed e¤ects when n is large, and T can be large, but small relative to n. By eliminating …xed e¤ects to begin with, we investigate asymptotic properties of the estimators, where exogenous and predetermined variables are used as instruments. For the spatial dynamic panel data model, as compared with the dynamic p...

environmental kuznets curve (ekc) is one of the known concepts in environmental economics developed dramatically over the last twenty years ago. one of the advances in studying the relationship between economic growth and environmental quality is concerning the spatial autocorrelation of ecological phenomena. the rationale behind spatial environmental kuznets curve (sekc) is similar to ekc incl...

The purpose of this study is to investigate the factors affecting the manufacturing industry wage among selected developing countries based on new economic geography theory. More specifically, we use a panel data model to study the spatial structure of wages in 136 countries for the period 1998-2007. The results indicate that this theory provides a good description of the spatial structure of w...

BACKGROUND Major outbreaks of hand, foot and mouth disease (HFMD) have been reported in China since 2008, posing a great threat to the health of children. Although many studies have examined the effect of meteorological variables on the incidence of HFMD, the results have been inconsistent. This study aimed to quantify the relationship between meteorological factors and HFMD occurrence in diffe...
