Weather Shocks and Output in Low-Income Countries: The Role of Policies and Adaptation


Book Description

We explore the extent to which macroeconomic policies, structural policies, and institutions can mitigate the negative relationship between temperature shocks and output in countries with warm climates. Empirical evidence and simulations of a dynamic general equilibrium model reveal that good policies can help countries cope with negative weather shocks to some extent. However, none of the adaptive policies we consider can fully eliminate the large aggregate output losses that countries with hot climates experience due to rising temperatures. Only curbing greenhouse gas emissions—which would mitigate further global warming—could limit the adverse macroeconomic consequences of weather shocks in a long-lasting way.




The Effects of Weather Shocks on Economic Activity: What are the Channels of Impact?


Book Description

Global temperatures have increased at an unprecedented pace in the past 40 years. This paper finds that increases in temperature have uneven macroeconomic effects, with adverse consequences concentrated in countries with hot climates, such as most low-income countries. In these countries, a rise in temperature lowers per capita output, in both the short and medium term, through a wide array of channels: reduced agricultural output, suppressed productivity of workers exposed to heat, slower investment, and poorer health. In an unmitigated climate change scenario, and under very conservative assumptions, model simulations suggest the projected rise in temperature would imply a loss of around 9 percent of output for a representative low-income country by 2100.




Shock Waves


Book Description

Ending poverty and stabilizing climate change will be two unprecedented global achievements and two major steps toward sustainable development. But the two objectives cannot be considered in isolation: they need to be jointly tackled through an integrated strategy. This report brings together those two objectives and explores how they can more easily be achieved if considered together. It examines the potential impact of climate change and climate policies on poverty reduction. It also provides guidance on how to create a “win-win†? situation so that climate change policies contribute to poverty reduction and poverty-reduction policies contribute to climate change mitigation and resilience building. The key finding of the report is that climate change represents a significant obstacle to the sustained eradication of poverty, but future impacts on poverty are determined by policy choices: rapid, inclusive, and climate-informed development can prevent most short-term impacts whereas immediate pro-poor, emissions-reduction policies can drastically limit long-term ones.




Adaptation Policy Frameworks for Climate Change


Book Description

Adaptation is a process by which individuals, communities and countries seek to cope with the consequences of climate change. The process of adaptation is not new; the idea of incorporating future climate risk into policy-making is. While our understanding of climate change and its potential impacts has become clearer, the availability of practical guidance on adaptation has not kept pace. The development of the Adaptation Policy Framework (APF) is intended to help provide the rapidly evolving process of adaptation policy-making with a much-needed roadmap. Ultimately, the purpose of the APF is to support adaptation processes to protect - and enhance - human well-being in the face of climate change. This volume will be invaluable for everyone working on climate change adaptation and policy-making.




Fiscal Impacts of Climate Disasters in Emerging Markets and Developing Economies


Book Description

Climate-induced disasters are causing increasingly frequent and intense economic damages, disproportionally affecting emerging markets and developing economies (EMDEs) relative to advanced economies (AEs). However, the impact of various types of climate shocks on output growth and fiscal positions of EMDEs is not fully understood. This research analyzes the macro-fiscal implications of three common climate disasters (droughts, storms, and floods) using a combination of macroeconomic data and comprehensive ground and satellite disaster indicators spanning the past three decades across 164 countries. Across EMDEs, where agriculture tends to be the principal sector, a drought reduces output growth by 1.4 percentage points and government revenue by 0.7 percent of GDP as it erodes the tax bases of affected countries. Meanwhile, likely reflecting limited fiscal space to respond to a disaster, fiscal expenditure does not increase following a drought. A storm drags output growth in EMDEs, albeit with negligible impact on fiscal revenue, but government expenditure increases due to reconstruction and clean-up efforts. We find only limited impact of localized floods on growth and fiscal positions. In contrast, AEs tend to experience negligible growth and fiscal consequences from climate-induced shocks. As these shocks have much more detrimental effects in EMDEs, international support for disaster preparedness and climate change adaptation play a crucial role for these countries to confront climate change.




Weather Shocks and Exchange Rate Flexibility


Book Description

This paper assesses the stabilization properties of fixed versus flexible exchange rate regimes and aims to answer this research question: Does greater exchange rate flexibility help an economy’s adjustment to weather shocks? To address this question, the impact of weather shocks on real per capita GDP growth is quantified under the two alternative exchange rate regimes. We find that although weather shocks are generally detrimental to per capita income growth, the impact is less severe under flexible exchange rate regimes. Moreover, the medium-term adverse growth impact of a 1 degree Celsius increase in temperature under a pegged regime is about –1.4 percentage points on average, while under a flexible regime, the impact is less than one half that amount (–0.6 percentage point). This finding bolsters the idea that exchange rate flexibility not only helps mitigate the initial impact of the shock but also promotes a faster recovery. In terms of mechanisms, our findings suggest that the depreciation of the nominal exchange rate under a flexible regime supports real export growth. In contrast to standard theoretical predictions, we find that countercyclical fiscal policy may not be effective under pegged regimes amid high debt, highlighting the importance of the policy mix and precautionary (fiscal) buffers.




Macroeconomic and Financial Policies for Climate Change Mitigation: A Review of the Literature


Book Description

Climate change is one of the greatest challenges of this century. Mitigation requires a large-scale transition to a low-carbon economy. This paper provides an overview of the rapidly growing literature on the role of macroeconomic and financial policy tools in enabling this transition. The literature provides a menu of policy tools for mitigation. A key conclusion is that fiscal tools are first in line and central, but can and may need to be complemented by financial and monetary policy instruments. Some tools and policies raise unanswered questions about policy tool assignment and mandates, which we describe. The literature is scarce, however, on the most effective policy mix and the role of mitigation tools and goals in the overall policy framework.




Fiscal Policies for Development and Climate Action


Book Description

This report provides actionable advice on how to design and implement fiscal policies for both development and climate action. Building on more than two decades of research in development and environmental economics, it argues that well-designed environmental tax reforms are especially valuable in developing countries, where they can reduce emissions, increase domestic revenues, and generate positive welfare effects such as cleaner water, safer roads, and improvements in human health. Moreover, these reforms need not harm competitiveness. New empirical evidence from Indonesia and Mexico suggests that under certain conditions, raising fuel prices can actually increase firm productivity. Finally, the report discusses the role of fiscal policy in strengthening resilience to climate change. It provides evidence that preventive public investments and measures to build fiscal buffers can help safeguard stability and growth in the face of rising climate risks. In this way, environmental tax reforms and climate risk-management strategies can lay the much-needed fiscal foundation for development and climate action.




Food for All


Book Description

This book is a historical review of international food and agriculture since the founding of the international organizations following the Second World War, including the World Bank and the Food and Agriculture Organization of the United Nations (FAO), the World Food Programme (WFP) and into the 1970s, when CGIAR was established and the International Fund for Agricultural Development (IFAD) was created to recycle petrodollars. Despite numerous international consultations and an increased number of actors, there has been no real growth in international assistance, except for the work of the Bill and Melinda Gates Foundation. The book concurrently focuses on the structural transformation of developing countries in Asia and Africa, with some making great strides in small farmer development and in achieving structural transformation of their economies. Some have also achieved Sustainable Development Goals (SDGs), particularly SDG2, but most have not. Not only are some countries, particularly in South Asia and sub-Saharan Africa, lagging behind, but they face new challenges of climate change, competition from emerging countries, population pressure, urbanization, environmental decay, and dietary transition. Lagging developing countries need huge investments in human capital, and physical and institutional infrastructure, to take advantage of rapid change in technologies, but the role of international assistance in financial transfers has diminished. The COVID-19 pandemic has not only set many poorer countries back but starkly revealed the weaknesses of past strategies. Transformative changes are needed in developing countries with international cooperation to achieve better outcomes. Will change in the United States bring new opportunities for multilateral cooperation?"--




Finance & Development, December 2019


Book Description

This issue of Finance & Development looks at the economic and financial impact of climate policy choices. It points to concrete solutions that offer growth opportunities, driven by technological innovation, sustainable investment, and a dynamic private sector. The private sector can stop supporting or subsidizing industries and activities that damage the planet and instead invest in sustainable development. Governments can roll out policies to fight climate change and the destruction of nature. The paper highlights that technological change and innovations are central to longer-term efforts to mitigate climate change by developing alternatives to fossil fuels. A new, sustainable financial system is under construction. It is funding the initiatives and innovations of the private sector and amplifying the effectiveness of governments’ climate policies—it could even accelerate the transition to a low-carbon economy. The Bank of England’s latest survey finds that almost three-quarters of banks are starting to treat the risks from climate change like other financial risks—rather than viewing them simply as a corporate social responsibility. Banks have begun to consider the most immediate physical risks to their business models—from the exposure of mortgage books to flood risk to the impact of extreme weather events on sovereign risk.
