This second edition of this important and authoritative survey provides students and researchers with up-to-date and accessible information about the ecology of freshwater and estuarine wetlands. Prominent scholars help students understand both general concepts of different wetland types as well as complex topics related to these dynamic physical environments. Careful syntheses review wetland soils, hydrology, and geomorphology; abiotic constraints for wetland plants and animals; microbial ecology and biogeochemistry; development of wetland plant communities; wetland animal ecology; and carbon dynamics and ecosystem processes. In addition, contributors document wetland regulation, policy, an...
A multidisciplinary review of salt marshes, describing how they function and respond to external pressures such as sea-level rise.
In this "bracingly iconoclastic” book (New York Times Book Review), a renowned economics scholar breaks down the fight to end global poverty and the rights that poor individuals have had taken away for generations. In The Tyranny of Experts, renowned economist William Easterly examines our failing efforts to fight global poverty, and argues that the "expert approved" top-down approach to development has not only made little lasting progress, but has proven a convenient rationale for decades of human rights violations perpetrated by colonialists, postcolonial dictators, and US and UK foreign policymakers seeking autocratic allies. Demonstrating how our traditional antipoverty tactics have b...
Most research into humans' impact on the environment has focused on large-scale societies; a corollary assumption has been that small scale economies are sustainable and in harmony with nature. The contributors to this volume challenge this notion, revealing how such communities shaped their environment—and not always in a positive way. Offering case studies from around the world—from Brazil to Japan, Denmark to the Rocky Mountains—the chapters empirically demonstrate the substantial transformations of the surrounding landscape made by hunter-gatherer and limited horticultural societies. Summarizing previous research as well as presenting new data, this book shows that the environmental impact and legacy of societies are not always proportional their size. Understanding that our species leaves a footprint wherever it has been leads to both a better understanding of our prehistoric past and to deeper implications for our future relationship to the world around us.
As of 2015, U.S. log output per capita was 12 percent below what its pre-2008 linear trend would predict. To understand why, I develop and estimate a model of the US with demographics, real and monetary shocks, and the occasionally binding ZLB on nominal rates. Demographic changes generate slow-moving trends in the real interest rate, employment, and productivity. I find that demographics alone can explain one-third of the gap between log output per capita and its linear trend in 2015. Demographics also lowered real rates, causing the ZLB to bind between 2009 and 2015, contributing to the slow recovery after the Great Recession.
The COVID-19 pandemic triggered a pronounced setback in the fight against global poverty—likely the largest setback since World War II. Many low- and middle-income countries have yet to see a full recovery. High indebtedness in many countries has hindered a swift recovery, while rising food and energy prices—fueled in part by conflict and climate shocks—have made a return to progress on poverty reduction more challenging than ever. These setbacks have altered the trajectory of poverty reduction in large and lasting ways. The world is significantly off course on the goal of ending extreme poverty by 2030.The year 2020 also marked a historic turning point as decades of global income conv...
Countries in middle-income East Asia and the Pacific were already experiencing serious learning deficits prior to the COVID-19 pandemic. COVID-related school disruptions have only made things worse. Learning poverty -- defined as the percentage of 10-year-olds who cannot read and understand an age-appropriate text -- is as high as 90 percent in several countries. Several large Southeast Asian countries consistently perform well below expectations on adolescent learning assessments. This report examines key factors affecting student learning in the region, with emphasis on the central role of teachers and teaching quality. It also analyzes the role education technologies, which came into widespread use during the pandemic, and examines the political economy of education reform. The report presents recommendations on how countries can strengthen teaching to improve learning and, in doing so, can enhance productivity, growth, and future development in the region.
Illustrated throughout, this book presents what is known about factors that "shift the balance" between accretion and erosion, recruitment and mortality, stony corals and filamentous algae, recovery and degradation - the life and death of coral reefs.
Exploring and updating the controversial debates about the relationship between democracy and development, this Research Handbook provides clarification on the complex and nuanced interlinkages between political regime type and socio-economic development. Distinguished scholars examine a broad range of issues from multidisciplinary perspectives across Africa, Asia, Europe, Latin America and the Middle East.
I use three decades of county-level data to estimate the effects of federal unemployment benefit extensions on economic activity. To overcome the reverse causality coming from the fact that benefit extensions are a function of state unemployment rates, I only use the within-state variation in outcomes to identify treatment effects. Identification rests on a differences-in-differences approach which exploits heterogeneity in county exposure to policy changes. To distinguish demand and supply-side channels, I estimate the model separately for tradable and non-tradable sectors. Finally I use benefit extensions as an instrument to estimate local fiscal multipliers of unemployment benefit transfers. I find (i) that the overall impact of benefit extensions on activity is positive, pointing to strong demand effects; (ii) that, even in tradable sectors, there are no negative supply-side effects from work disincentives; and (iii) a fiscal multiplier estimate of 1.92, similar to estimates in the literature for other types of spending.
