| Abstract: | In several markets, firms compete not for consumer expenditure but instead for consumer attention. We model and characterize how households allocate their scarce attention in arguably the largest market for attention: the Internet. Our characterization of household attention allocation operates along three dimensions: how much attention is allocated, where that attention is allocated, and how that attention is allocated. Using click-stream data for thousands of U.S. households, we assess if and how attention allocation on each dimension changed between 2008 and 2013, a time of large increases in online offerings. We identify vast and expected changes in where households allocate their attention (away from chat and news towards video and social media), and yet we simultaneously identify remarkable stability in how much attention is allocated and how it is allocated. Specifically, we identify (i) persistence in the elasticity of attention according to income and (ii) complete stability in the dispersion of attention across sites and in the intensity of attention within sites. We illustrate how this finding is difficult to reconcile with standard models of optimal attention allocation and suggest alternatives that may be more suitable. We conclude that increasingly valuable offerings change where households go online, but not their general online attention patterns. This conclusion has important implications for competition and welfare in other markets for attention. |

| Abstract: | Using data for 49 African countries over the years spanning 2000-2012, and controlling for a wide range of factors, this study empirically assesses the effects of formal institutions on ICT adoption in developing countries. It deploys 2SLS and FE regression models, (a) to estimate what determines ICT adoption and (b) to trace how ICT adoption affects inclusive development. The results show that formal institutions affect ICT adoption in this group of countries, with government effectiveness having the largest positive effect and regulations the largest negative effect. Generally, formal institutions appear more important to ICT adoption in low income countries than middle income countries, whereas population and economic growth tend to constrain ICT adoption with low income countries more negatively affected than middle income countries. The results further demonstrate that ICT adoption affects development strongly, and that such effects are comparable to those of domestic credit and foreign direct investment. Ceteris paribus, external factors like foreign aid are more limiting to inclusive development than internal factors. This suggests that developing countries can enhance their ICT adoption for development by improving formal institutions and by strengthening domestic determinants of ICT adoption. Both represent opportunities for further research. |

| Abstract: | A recent World Bank report reveals that poverty has been decreasing in all regions of the world with the exception of sub-Saharan Africa (SSA) as more than 45% of countries in the sub-region are off-track from achieving the Millennium Development Goal (MDG) extreme poverty target. This paper investigates the effects of mobile phone technology, knowledge creation and diffusion on inclusive human development in 49 SSA countries for the period 2000-2012 using Tobit model. The study finds that mobile phone penetration in SSA is pivotal to sustainable and inclusive human development irrespective of the country’s level of income, legal origins, religious orientation and the state of the nation. However, the pupil-teacher ratio exerts a negative influence on inclusive human development. The net effects of interactions between the mobile phone and knowledge diffusion variables are positive. |
