    Parallel Title: Erscheint auch als Hoang, Trung Xuan Labor Market Impacts and Responses: The Economic Consequences of a Marine Environmental Disaster
    Keywords: Graue Literatur
    Abstract: This paper examines the labor market impacts of a large-scale marine environmental crisis caused by toxic chemical contamination in Vietnam's central coast in 2016. Combining labor force surveys with satellite data on fishing-boat detection, the analysis finds negative and heterogeneous impacts on fishery incomes and employment and uncovers interesting coping patterns. Satellite data suggest that upstream fishers traveled to safe fishing grounds, and thus bore lower income damage. Downstream fishers, instead, endured severe impact and were more likely to substitute fishery hours for working secondary jobs. The paper also finds evidence on an impact recovery to fishing intensity and fishery income, and a positive labor market spillover to freshwater fishery

    Abstract: Offers comprehensive insight into the theory, models, and techniques of ultra-dense networks and applications in 5G and other emerging wireless networks The need for speed—and power—in wireless communications is growing exponentially. Data rates are projected to increase by a factor of ten every five years—and with the emerging Internet of Things (IoT) predicted to wirelessly connect trillions of devices across the globe, future mobile networks (5G) will grind to a halt unless more capacity is created. This book presents new research related to the theory and practice of all aspects of ultra-dense networks, covering recent advances in ultra-dense networks for 5G networks and beyond, including cognitive radio networks, massive multiple-input multiple-output (MIMO), device-to-device (D2D) communications, millimeter-wave communications, and energy harvesting communications. Clear and concise throughout, Ultra-Dense Networks for 5G and Beyond - Modelling, Analysis, and Applications offers a comprehensive coverage on such topics as network optimization; mobility, handoff control, and interference management; and load balancing schemes and energy saving techniques. It delves into the backhaul traffic aspects in ultra-dense networks and studies transceiver hardware impairments and power consumption models in ultra-dense networks. The book also examines new IoT, smart-grid, and smart-city applications, as well as novel modulation, coding, and waveform designs. One of the first books to focus solely on ultra-dense networks for 5G in a complete presentation Covers advanced architectures, self-organizing protocols, resource allocation, user-base station association, synchronization, and signaling Examines the current state of cell-free massive MIMO, distributed massive MIMO, and heterogeneous small cell architectures Offers network measurements, implementations, and demos Looks at wireless caching techniques, physical layer security, cognitive radio, energy harvesting, and D2D communications in ultra-dense networks Ultra-Dense Networks for 5G and Beyond - Modelling, Analysis, and Applications is an ideal reference for those who want to design high-speed, high-capacity communications in advanced networks, and will appeal to postgraduate students, researchers, and engineers in the field.

    Parallel Title: Erscheint auch als Print Version: Islamaj, Ergys Lives versus Livelihoods during the COVID-19 Pandemic: How Testing Softens the Trade-Off
    Keywords: Coronavirus ; Wirtschaftskrise ; Lockdown ; Infektionsschutz ; Welt
    Abstract: The early COVID-19 pandemic literature focused on the conflict between lives and livelihoods. But cross-country evidence reveals that across countries high mortality rates were often associated with large gross domestic product contractions. This paper shows that the presumed trade-off was associated with lockdowns as the primary instrument of containment. Early transition from lockdowns to testing-tracing-isolation-based containment softened the trade-off within countries and explains the absence of a trade-off across countries. The analysis finds that testing had positive indirect effects on growth and perhaps even positive direct effects. By allowing countries to relax shutdowns without compromising on containment, testing could have indirectly contributed to about a 0.6 percentage point boost in growth. By infusing greater confidence in people to step out and engage in economic activity, testing could have added another 0.6 percentage point to growth. As the world struggles to scale up vaccination in the face of new waves and variants, continued emphasis on testing could help limit infection without recourse to costly lockdowns

    Parallel Title: Erscheint auch als Islamaj, Ergys Firm Entry, Exit and Suspension: Evidence from Household Businesses in Vietnam
    Keywords: Employment and Unemployment ; Home-Based Work ; Household Business Resilience ; Informal Employment ; Informal Sector ; Informality Impact of COVID-19 ; Labor and Employment Law ; Labor Markets ; Law and Development ; Poverty Reduction ; Self-Employment ; Social Protections and Labor ; Tax Registered Home Business Resilience ; Work and Working Conditions
    Abstract: Household businesses make up the majority of firms in developing economies. This paper uses a novel tax census database that covers the universe of tax-registered household businesses to analyze the entry and exit of owner-operated firms in Vietnam during January 2018 to August 2020. It documents new stylized facts about the survival dynamics of informal businesses. First, the entry and exit rates were about 5-6 percent a year for tax-registered household businesses during the pre-pandemic period. Second, an additional 25 percent of household businesses suspended their activity in a year on average, with the annual suspension duration exceeding 2.5 months. The suspension rate spiked to 40 percent during the onset of the COVID-19 pandemic in 2020. Third, the findings show that the pandemic-related effects were more pronounced for businesses dependent on face-to-face interactions with customers and suppliers. However, these effects were short lived, and activity and earnings rebounded by August 2020. The findings may reflect the relatively short COVID-19 distress in Vietnam during the first phase of the pandemic, but they illuminate both the vulnerabilities and resilience of the household business sector
