| Abstract: | We develop a simple North-South model of quality ladders to show that the virtual mobility of labor across time zones, facilitated by the advance in communication technology, can raise the endogenous growth rate of the world economy. The unique balanced growth rate is increasing in the endowments of skilled labor in both countries and decreasing in the rate of impatience. Moreover, we find that partial R&D offshoring to the South has initially a negative effect on the level of skilled wages in the North, but this is compensated for by its positive effect on the growth rate in both North and South. |

| Abstract: | The widespread availability of internet search data is a new source of high-frequency information that can potentially improve the precision of macroeconomic forecasting, especially in areas with data constraints. This paper investigates whether travel-related online search queries enhance accuracy in the forecasting of tourist arrivals to The Bahamas from the U.S. The results indicate that the forecast model incorporating internet search data provides additional information about tourist flows over a univariate approach using the traditional autoregressive integrated moving average (ARIMA) model and multivariate models with macroeconomic indicators. The Google Trends-augmented model improves predictability of tourist arrivals by about 30 percent compared to the benchmark ARIMA model and more than 20 percent compared to the model extended only with income and relative prices. |

| Abstract: | Can large-scale peer interaction foster entrepreneurship and innovation? We conducted an RCT involving almost 5,000 entrepreneurs from 49 African countries. All were enrolled in an online business course, and the treatment involved random assignment to either face-to-face or virtual (Internet-mediated) interaction. We find positive treatment effects on both the submission of business plans and their quality, provided interaction displays some intermediate diversity. Network effects are also significant on both outcomes, although diversity plays a different role for each. This shows that effective peer interaction can be feasibly implemented quite broadly but must also be designed carefully, in view of the pursued objectives. |

| Abstract: | In a previous paper (The Digital World: I - Bitcoin: from history to real live, Guégan, 2018), we explain some limits and interests of the Bitcoin system and why the central bankers and regulators need to take some decision on its existence. In this article, we develop some alternatives to the Bitcoin blockchain which are considered by the banking system and industries. |

| Abstract: | The digital revolution has brought about a wave of technological optimism, sustained by all the things technology does for us in our every day lives. This is in principle good, but it has a dark side, as the poor use of the new technologies may lead us to become lazier and to replace or strain rational processes of deliberation with the mechanical accumulation of numbers and data, which, allegedly, help objective and clear decision-making. This dark side produces a number of pathologies, which we could term "digitalitis." Manifestations of digitalitis include top5itis in the world of academic publishing, VAR-itis in the world of soccer, scooteritis in the world of means of transportation, or digital populism in democratic societies. |

| Abstract: | Smart cities that make broad use of digital technologies have been touted as possible solutions for the population pressures faced by many cities in developing countries and may help meet the rising demand for services and infrastructure. Nevertheless, the high financial cost involved in infrastructure maintenance, the substantial size of the informal economies, and various governance challenges are curtailing government idealism regarding smart cities. This review examines the state of smart city development in developing countries, which includes understanding the conceptualisations, motivations, and unique drivers behind (and barriers to) smarty city development. A total of 56 studies were identified from a systematic literature review from an initial pool of 3928 social sciences literature identified from two academic databases. Data were analysed using thematic synthesis and thematic analysis. The review found that technology-enabled smart cities in developing countries can only be realised when concurrent socioeconomic, human, legal, and regulatory reforms are instituted. Governments need to step up their efforts to fulfil the basic infrastructure needs of citizens, raise more revenue, construct clear regulatory frameworks to mitigate the technological risks involved, develop human capital, ensure digital inclusivity, and promote environmental sustainability. A supportive ecosystem that encourages citizen participation, nurtures start-ups, and promotes public-private partnerships needs to be created to realise their smart city vision. |
