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.

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.

Book Description

We study the long-term impact of climate change on economic activity across countries, using a stochastic growth model where labor productivity is affected by country-specific climate variables—defined as deviations of temperature and precipitation from their historical norms. Using a panel data set of 174 countries over the years 1960 to 2014, we find that per-capita real output growth is adversely affected by persistent changes in the temperature above or below its historical norm, but we do not obtain any statistically significant effects for changes in precipitation. Our counterfactual analysis suggests that a persistent increase in average global temperature by 0.04°C per year, in the absence of mitigation policies, reduces world real GDP per capita by more than 7 percent by 2100. On the other hand, abiding by the Paris Agreement, thereby limiting the temperature increase to 0.01°C per annum, reduces the loss substantially to about 1 percent. These effects vary significantly across countries depending on the pace of temperature increases and variability of climate conditions. We also provide supplementary evidence using data on a sample of 48 U.S. states between 1963 and 2016, and show that climate change has a long-lasting adverse impact on real output in various states and economic sectors, and on labor productivity and employment.

Book Description

Local weather shocks have been shown to affect local economic output, however, little is known about their propagation through production networks. Using a six-sector global dataset over the past fifty years, this paper examines the effect of weather fluctuations and extreme weather events on sectoral economic production and the transmission of weather shocks across sectors, countries and over time. I document that agriculture is the most harmed sector by heat shocks, droughts and cyclones. Using input-output interlinkages, I find that sectors at later stages of the supply chain suffer from substantial and persistent losses over time due to domestic and foreign heat shocks in other sectors. A counterfactual analysis of the average annual output loss accounting for heat shocks across trade partners shows a substantial underestimation of the economic cost of temperature increases since 2000.

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.

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.

Book Description

What is the impact of climate change on inflation and growth dynamics? This is not a simple question to answer as climate shocks tend to be ubiquitous, but with opposing effects simultaneously on demand and supply. The extent of which climate-related shocks affect inflation and economic growth also depends on long-run scarring in the economy and the country’s fiscal and institutional capacity to support recovery. In this paper, we use the local projection method to empirically investigate how climate shocks, as measured by climate-induced natural disasters, influence inflation and economic growth in a large panel of countries over the period 1970–2020. The results shows that both inflation and real GDP growth respond significantly but also differently in terms of direction and magnitude to different types of disasters caused by climate change. We split the full sample of countries into income groups—advanced economies and developing countries—and find a striking contrast in the impact of climate shocks on inflation and growth according to income level, state of the economy, and fiscal space when the shock hits.

Book Description

We use a new dataset to estimate the impact of temperature on economic activity at a more geographically and temporally disaggregated level than the existing literature. Analyzing 30-kilometer grid cells at a monthly frequency, temperature has a negative, highly statistically significant, and quantitatively large effect on output: a 1 °C increase in monthly temperature is associated with a 0.77 percent reduction in nighttime lights, a proxy for local economic activity. The effects of even a temporary increase in temperature persist for almost one year after the shock. Increases in temperature have an especially large, negative impact on growth in poorer countries, indicating that they are more vulnerable to the impact of climate change.

Book Description

Central America is one of the world’s most vulnerable regions to extreme climate events. The literature estimates the macroeconomic effects of climate events mainly using annual data, which might underestimate the true effects as these extreme events tend to be short-lived and generate government and family support in response. To overcome this limitation, this paper studies Central American countries’ macroeconomic impact of climatic disasters using high-frequency (monthly) data over the period 2000-2019. We identify extreme climate events by defining dummy variables related to storm and flood events reported in the EM-DAT (Emergency Events Database) and estimate country-specific VAR and panel VAR. The results suggest that a climatic disaster drops monthly economic activity in most countries in the region of around 0.5 to 1 percentage points on impact, with persistent effects on the level of GDP. We show that even as extreme climate events were relatively less severe under our sample period, quantitative effects are similar or larger than previously estimated for the region. In addition, remittances (transfers from family living abroad) increase for most countries in response to a extreme climate event, acting as a shock absorber. The results are robust to controlling for the severity of the climate events, for which we construct a monthly climate index measuring severity of weather indicators by following the spirit of the Actuaries Climate Index (ACI).
