    The recent deployment of fibre-optic submarine cables (SMCs) in sub-Saharan Africa (SSA) raised the prospects for the digital economy expansion and the whole sub-continent take-off, but also exposed countries and populations to new sources of vulnerability. This paper provides empirical evidence on the ambivalent effect of SMC deployment on the digital divide in 46 SSA countries. On the one hand, results show that the laying of SEACOM, MainOne and EASSy cables in 2009-2010 has yielded a three percentage points increase in internet penetration rates. This is a huge increase, meaning that the deployment of these cables has almost doubled the penetration of Internet in the sub-continent's population. On the other hand, exogenous sources of telecommunication disruptions related to SMC laying - the country's exposure to SMC outages and digital isolation - are found to reduce internet and mobile penetration rates, to lower investments in ICTs, and to increase mobile-cellular tariffs and the wireline network instability. Therefore, while SMC arrival in SSA has reduced the digital divide, this divide would be lower if SSA countries were less digitally vulnerable.

    The Internet has significantly expanded worldwide, changing our relationship with the world, and the way we communicate, educate, and inform ourselves. Africa, despite having a very low number of fixed-broadband subscriptions for 100 inhabitants, has not escaped the Internet phenomenon, as the number of individuals with Internet access has risen from 2 in 2002 to 39.7 (per 100 inhabitants) in 2022. Similarly, the number of individuals with mobile- cellular telephone subscriptions has jumped from 12.4 in 2002 to 86.3 (per 100 inhabitants) in 2022 (ITU, 2022).

    This paper addresses the effects of the revolving door phenomenon on the inequality of influence among firms. It shows that firms are not equal in their capacities to benefit from state connections. We first develop a theoretical model introducing the notion of "bureaucratic capital" and showing how the revolving door generates inequality in bureaucratic capital and in profits leading to inequality of influence. Then, this prediction is tested on a new database tracking the revolving door process involving the 20 biggest US commercial banks. We show that regulators who have created a large stock of "bureaucratic capital" are more likely to be hired by the top five banks after leaving public office. We then develop indices of the inequality of influence between banks. We show that banks in the top revenue quintile concentrate around 80% of the stock of revolvers. Goldman Sachs appears as the prime beneficiary of this process, by concentrating almost 30% of the revolving door phenomenon.
