Digital platforms controlled by Alibaba, Alphabet, Amazon, Facebook, Netflix, Tencent and Uber have transformed not only the ways we do business, but also the very nature of people's everyday lives. It is of vital importance that we understand the economic principles governing how these platforms operate. This book explains the driving forces behind any platform business with a focus on network effects. The authors use short case studies and real-world applications to explain key concepts such as how platforms manage network effects and which price and non-price strategies they choose. This self-contained text is the first to offer a systematic and formalized account of what platforms are and how they operate, concisely incorporating path-breaking insights in economics over the last twenty years.
This timely and much-needed Handbook reconsiders an old topic from a fresh perspective, raising a number of new, interesting and worthwhile issues in the wake of ten years of globalization. This comprehensive analysis illustrates that old-style industrial policies whereby the government directly intervened in markets, and was often the producer itself, are no longer relevant. Structural changes occurring in economies summarized in the term globalization are triggering the definition and implementation of new industrial policies. The contributors, leading experts in their field, unite to evaluate this shift of over a decade ago. Employing various empirical and methodological approaches with a strong theoretical underpinning, this world-wide study of the state-of-the-art of industrial policy issues is an invaluable reference tool. It has been enthusiastically received by a wide-ranging audience including scholars, researchers and policy makers with an interest in industrial economics and policy, business studies and policies for growth, competitiveness and development.
Studies of African economic development frequently focus on the daunting challenges the continent faces. From recurrent crises to ethnic conflicts and long-standing corruption, a raft of deep-rooted problems has led many to regard the continent as facing many hurdles to raise living standards. Yet Africa has made considerable progress in the past decade, with a GDP growth rate exceeding five percent in some regions. The African Successes series looks at recent improvements in living standards and other measures of development in many African countries with an eye toward identifying what shaped them and the extent to which lessons learned are transferable and can guide policy in other nations and at the international level. The second volume in the series, African Successes: Human Capital turns the focus toward Africa’s human capital deficit, measured in terms of health and schooling. It offers a close look at the continent’s biggest challenges, including tropical disease and the spread of HIV.
I use a monthly panel of provincially-collected central government revenues and conflict fatalities to estimate government revenues lost due to conflict in Afghanistan since 2005. I identify causal effects by instrumenting for conflict using pre-sample ethno-linguistic share. Headline estimates are very large, implying total revenue losses since 2005 of $3bn, and future revenue gains from peace of about 6 percent of GDP per year. Reduced collection efficiency, rather than lower economic activity, appears to be the key channel. OLS estimates understate the causal effect by a factor of four. Comparing to estimates from Powell’s (2017) generalized synthetic control method suggests that this bias results from omitted variables and measurement error in equal share. The findings underscore the considerable economic loss due to conflict, and the importance of careful identification in measuring this loss.
This study—which includes a pilot intervention in Kenya—aims to further the state of knowledge about the emerging trend of disruptive agricultural technologies (DATs) in Africa, with a focus on supply-side dynamics. The first part of the study is a stocktaking analysis to assess the number, scope, trend, and characteristics of scalable disruptive technology innovators in agriculture in Africa. From a database of 434 existing DAT operations, the analysis identified 194 as scalable. The second part of the study is a comparative case study of Africa’s two most successful DAT ecosystems in Kenya and Nigeria, which together account for half of Sub-Saharan Africa’s active DATs. The objective of these two case studies is to understand the successes, challenges, and opportunities faced by each country in fostering a conducive innovation ecosystem for scaling up DATs. The case study analysis focuses on six dimensions of the innovation ecosystem in Kenya and Nigeria: finance, regulatory environment, culture, density, human capital, and infrastructure. The third part of the study is based on the interactions and learnings from a pilot event to boost the innovation ecosystem in Kenya. The Disruptive Agricultural Technology Innovation Knowledge and Challenge Conference in Nairobi, Kenya, brought together more than 300 key stakeholders from large technology companies, agribusiness companies, and public agencies; government representatives and experts from research and academic institutions; and representatives from financial institutions, foundations, donors, and venture capitalists. Scaling Up Disruptive Agricultural Technologies in Africa concludes by establishing that DATs are demonstrating early indications of a positive impact in addressing food system constraints. It offers potential entry points and policy recommendations to facilitate the broader adoption of DATs and improve the overall food system.
One of the most enduring questions in economics involves how a nation could accelerate the pace of its economic development. One of the most enduring answers to this question is to promote exports -either because doing so directly influences development via encouraging production of goods for export, or because export promotion permits accumulation of foreign exchange which permits importation of high-quality goods and services, which can in turn be used to expand the nation's production possibilities. In either case, growth is said to be export-led; the latter case is the so-called "two-gap" hypothesis (McKinnon, 1964; Findlay, 1973). The early work on export-led growth consisted of static cross-country com parisons (Michaely, 1977; Balassa, 1978; Tyler, 1981; Kormendi and Meguire, 1985). These studies generally concluded that there is strong evidence in favour of export-led growth because export growth and income growth are highly correlated. However, Kravis pointed out in 1970 that the question is an essen tially dynamic one: as he put it, are exports the handmaiden or the engine of growth? To make this determination one needs to look at time series to see whether or not exports are driving income. This approach has been taken in a number of papers (Jung and Marshall, 1985; Chow, 1987; Serletis, 1992; Kunst and Marin, 1989; Marin, 1992; Afxentiou and Serletis, 1991), designed to assess whether or not individual countries exhibit statistically significant evidence of export-led growth using Granger causality tests.
"Manu Saadia has managed to show us one more reason, perhaps the most compelling one of all, why we all need the world of Star Trek to one day become the world we live in." — Chris Black, Writer and Co-Executive Producer, Star Trek: Enterprise What would the world look like if everybody had everything they wanted or needed? Trekonomics, the premier book in financial journalist Felix Salmon's imprint PiperText, approaches scarcity economics by coming at it backwards — through thinking about a universe where scarcity does not exist. Delving deep into the details and intricacies of 24th century society, Trekonomics explores post-scarcity and whether we, as humans, are equipped for it. What are the prospects of automation and artificial intelligence? Is there really no money in Star Trek? Is Trekonomics at all possible?
The 2015 Paris Accord stated the aim to limit the increase in global mean temperatures to 2°C compared to pre-industrial levels and if possible, keep it down to 1.5°C. Achieving this is possible, but the costs incurred are uncertain and the distribution of costs among nations is indistinct. Furthermore, even if the goal is realised, significant impacts from climate change can be expected. Evidence indicates that these will be felt most severely in countries that are relatively poor. These effects of climate change will be added to by the measures taken to reduce GHGs. Together, they will determine how climate change affects the prospects for development across the globe. The analysis of the interplay between climate change and policies to combat it on the one hand and development on the other are the focus of this book.
Increasingly, economic development experts are abandoning traditional approaches to economic development that rely on recruiting large enterprises with tax breaks, financial incentives, and other inducements. Instead, they are relying on building businesses from the ground up and supporting the growth of existing enterprises. This paper explores whether promoting entrepreneurship and small businesses makes sense as an economic development strategy. It concludes that it probably does, but with some caveats. Small businesses are potent job creators, but so are large businesses. The attribution of the bulk of net job creation to small businesses arises largely from relatively large job losses at large firms, not to especially robust job creation by small firms. More important, data show that, on average, large businesses offer better jobs than small businesses, both in terms of compensation and stability. Further, there is little convincing evidence to suggest that small businesses have an edge over larger businesses in innovation. More research is needed to properly evaluate the case for a small business strategy, and indeed, to determine whether or not public engagement in economic development itself is a cost-effective and worthwhile pursuit.
