We apply a heterogenous coefficient spatial autoregressive panel model from Aquaro, Bailey and Pesaran (2015) to explore competition/cooperation by Berlin fueling stations in setting prices for diesel and E5 fuel. Unlike the maximum likelihood estimation method set forth by Aquaro, Bailey and...

Researchers typically encounter missing data in practice and have developed various imputation methods. However, the existing methods are mainly developed for independent data and the assumption of independence disregards the connections of units through various social relationships (e.g.,...

While many empirical studies show that participation in rural labor markets is animportant household livelihood strategy, data on Tanzania show that the participation in the rural labor markets is still relatively low. This study examines the factors behind the development of village labor...

In this study, we propose simple test statistics for identifying the source of spatial dependence in spatial autoregressive models with endogenous weights matrices. Elements of the weights matrices are modelled in such a way that endogenity arises when the unobserved factors that affect elements...

We provide various norm-based definitions of different types of cross-sectional dependence and the relations between them. These definitions facilitate to comprehend and to characterize the various forms of cross-sectional dependence, such as strong, semi-strong, and weak dependence. Then we...
