| Abstract: | This study investigates government quality determinants of ICT adoption using Generalised Method of Moments on a panel of 49 Sub-Saharan African (SSA) countries for the period 2000-2012. ICT is measured with mobile phone penetration, internet penetration and telephone penetration rates while all governance dimensions from the World Bank Governance Indicators are considered, namely: political governance (consisting of political stability and “voice & accountability”); economic governance (entailing government effectiveness and regulation quality) and institutional governance (encompassing the rule of law and corruption-control). The following findings are established. First, political stability and the rule of law have positive short run and negative long term effects on mobile phone penetration. Second, the rule of law has a positive (negative) short run (long term) effect on internet penetration. Third, government effectiveness and corruption-control have positive short run and long term effects on telephone penetration. Institutional governance appears to be most significant in determining ICT adoption in SSA. |

| Abstract: | This report explores the latest available statistics up to 2014 for the business demography of the Information and Communication Technologies (ICT) economic sector in Europe. It combines relevant databases which provide insights into the Member States’ ICT performance. The first four sections of this report take into account information, primarily from Eurostat, on ICT business demography. In the fifth section, radar charts are employed to combine Eurostat figures with information from the project on Prospective Insights in ICT R&D – phase 3 (PREDICT) in order to gain further insights into the association of relevant ICT variables across European countries. Selected economic indicators from Eurostat are also included in the final section in order to reveal patterns of associations between ICT and the economy. |

| Abstract: | This study provides new identification and estimation results for ascending (traditional English or online) auctions with unobserved auction-level heterogeneity and an unknown number of bidders. When the seller's reserve price and two order statistics of bids are observed, we derive conditions under which the distributions of buyer valuations, unobserved heterogeneity, and number of participants are point identified. We also derive conditions for point identification in cases where reserve prices are binding (in which case bids may be unobserved in some auctions) and present general conditions for partial identification. We propose a nonparametric maximum likelihood approach for estimation and inference. We apply our approach to the online market for used iPhones and analyze the effects of recent regulatory changes banning consumers from circumventing digital rights management technologies used to lock phones to service providers. We find that buyer valuations for unlocked phones dropped after the unlocking ban took effect. |
