This paper investigates the construction of moment conditions in discrete choice panel data with individual specific fixed effects. We describe how to systematically explore the existence of moment conditions that do not depend on the fixed effects, and we demonstrate how to construct them when...

Saving is an important factor in households' welfare in developing countries. However, most studies have focused on urban areas and at the macroeconomic level. Consequently, such studies mask the reality of rural households, which constitute a large proportion in Ethiopia. Hence, this study aims...

This article proposes a method to construct feasible solutions for dial-a-ride problem. Dial-a-ride problem is a routing problem for a set of time-constrained travel requests using a limited number of capacity-constrained vehicles. Obtaining a feasible solution can help identifying an upper...

This study applied a logistic regression model to determine the odds ratio of selecting clean ver- sus unclean energy as the main household fuel choice. This study also undertook to establish the coefficients of the factors determining household fuel energy choice. A large microeconomic dataset...
