Many studies have been focusing on the impact of the shale gas boom on our society, but the reverse relationship is not well documented. The objective of this paper is to examine the impact of oil and gas prices on shale gas drilling activities. We analyze the well-level production data from all major producing shale gas plays in the United States (US) and identify a major productivity shock in 2009. We then estimate the price elasticity of shale gas drilling using the econometric methods.

The study attempts to estimate the demand for cigarettes in Tanzania and presents simulation results on the effect of the cigarette excise tax on smoking participation, government revenue, and related topics. After briefly summarizing the magnitude and spread of cigarette consumption in the country, the paper reviews some empirical estimates from African and other countries. The 2008 Tanzanian household budget survey was used to estimate the demand for cigarettes in Tanzania.

Abstract: In this paper, we analyze water demand by urban households in Rwanda who currently lack a piped connection into their home. The analysis uses data from a cross-sectional survey. The results show that public taps are the most widely used water source and that the demand for water from this source is more inelastic than that for water from other water sources. Although some households combine different sources of water, the majority in the sample uses only one source.
