This paper studies the effect of climate change mitigating policies on innovation in clean energy technologies. Results suggest that the tightening of environmental policies since the early 1990s have made a statistically and economically significant contribution to the increase in clean innovation. These effects generally materialized quickly, within 2 to 3 years of the policy change, and were driven by individually significant marginal effects of both market-based policies – such as feed-in tariffs and trading schemes – as well as non-market policies, such as R&D subsidies or emission limits. Looking at electricity innovation in particular, the paper finds that the estimated effect on total innovation is positive on net, meaning that increased innovation in clean and grey technologies is not offset by a decrease in innovation in dirty technologies. From a policy point of view, the paper’s results call for strong policy efforts to decisively shift innovation towards clean technologies.

This paper estimates multipliers for spending in clean energy and biodiversity conservation to help inform stimulus measures for a post-COVID-19 sustainable recovery. Using a new international dataset, part of which was especially assembled for this analysis, we find that every dollar spent on key carbon-neutral or carbon-sink activities—from zero-emission power plants to the protection of wildlife and ecosystems—can generate more than a dollar’s worth of economic activity. The estimated multipliers associated with green spending are about 2 to 7 times larger than those associated with non-eco-friendly expenditure, depending on sectors, technologies and horizons. These findings survive several robustness checks and suggest that ‘building back better’ could be a win-win for economies and the planet.
The global economy is climbing out from the depths to which it had plummeted during the Great Lockdown in April. But with the COVID-19 pandemic continuing to spread, many countries have slowed reopening and some are reinstating partial lockdowns to protect susceptible populations. While recovery in China has been faster than expected, the global economy’s long ascent back to pre-pandemic levels of activity remains prone to setbacks.

This paper discusses sectoral policies needed to achieve the ambitious greenhouse gas (GHG) emissions reduction targets announced in the European Union’s Green Deal, complementing the companion paper “EU Climate Mitigation Policy”, which focuses on broader EU-level policies.
With total emissions nearly a quarter below their 1990 level, the EU has made important progress, but the new goals will require much stronger policy action. Moreover, progress has varied across sectors. Emissions from power and industry have fallen by about a third, buildings by a quarter and agriculture by a fifth – while transport emissions have risen. This paper argues that this divergence reflects differences in effective carbon prices, but also cost differences among the available abatement channels, market imperfections, and policy gaps. It discusses specific sectoral policies needed to address these factors and achieve the new emissions reduction goals.
This paper reviews the significant macro-fiscal challenges posed by climate change in
Djibouti and the costs of mitigation and adaptation policies. The paper concludes that
Djibouti is susceptible to climate change and related costs are potentially large. Investing
now in adaptation and mitigation has large benefits in terms of reducing the related costs in
the future. Reforms to generate the fiscal space are therefore needed and investment for
mitigation and adaptation to climate change should be built into the long-term fiscal
projections. Finally, concerted international efforts and stepping up regional cooperation
could help moderate climate-related macro-fiscal risks.
This paper takes stock of Seychelles’ plans to manage climate change, from the perspective of its macroeconomic implications. It suggests macro-relevant reforms that could strengthen the plans’ likelihood of success. It highlights high public awareness and a body of existing sustainable development planning, which puts Seychelles several steps ahead toward preparedness. Next steps would be to ensure that climate change planning is integrated with the forthcoming National Development Plan. Disaster preparedness is a relatively strong point, but there is much still to be done—from improving warning systems to resilience building to contingency financing.
This Economic Development Document highlights the Moldova 2020 National Development Strategy focus on producing a social and economic impact on various development priorities. Poverty reduction has progressed significantly during the past eight years: the national poverty rate decreased from 26.4 percent in 2008 to 9.6 percent in 2015. Remittances by emigrants and higher agricultural income, salaries, and social benefits were the major drivers of poverty reduction. The means-tested social assistance program had a significant impact. This social aid has proved to be the most efficient social protection against poverty; however, social support programs that are not means tested are ineffective.
This paper studies the economic costs of hurricanes in the Caribbean by constructing a
novel dataset that combines a detailed record of tropical cyclones’ characteristics with
reported damages. I estimate the relation between hurricane wind speeds and damages in
the Caribbean; finding that the elasticity of damages to GDP ratio with respect to
maximum wind speeds is three in the case of landfalls. The data show that hurricane
damages are considerably underreported, particularly in the 1950s and 1960s, with
average damages potentially being three times as large as the reported average of 1.6
percent of GDP per year. I document and show that hurricanes that do not make landfall
also have considerable negative impacts on the Caribbean economies. Finally, I estimate
that the average annual hurricane damages in the Caribbean will increase between 22 and
77 percent by the year 2100, in a global warming scenario of high CO2 concentrations and
high global temperatures.
