While a carbon tax is widely acknowledged as an efficient policy to mitigate climate change, adoption has lagged. Part of the challenge resides in the distributional implications of a carbon tax and a belief that it tends to be regressive. Even when not regressive, poor households could be hurt...

The small states of the Asia and Pacific region face unique challenges in raising their growth potential and living standards relative to other small states due to their small populations, geographical isolation and dispersion, narrow export and production bases, exposure to shocks, and heavy...

We use a dynamic small open economy model to explore the macroeconomic impact of alternative public investment scaling-up scenarios, analyzing how improving the efficiency of capital spending and of tax revenue collection affect growth and debt sustainability for three fast-growing Southeast...

Senegal's fiscal deficit and public debt have been on the rise in recent years owing partly to an ailing and inefficient oil-based energy sector. In this paper we use a two-sector, open-economy, dynamic general equilibrium model to investigate the effects of varying fiscal policy instruments one...

This paper assesses the implications of the use of oil revenue for public investment on growth and fiscal sustainability in Cameroon. We develop a dynamic stochastic general equilibrium model to analyze the effects of such investment on growth and on the path of key fiscal indicators, such as...

This paper explores the role of trade instruments in globally efficient climate policies, focusing on the central issue of whether some form of border tax adjustment (BTA) is warranted when carbon prices differ internationally. It shows that tariff policy has a role in easing cross-country...

This paper recommends a system of upstream taxes on fossil fuels, combined with refunds for downstream emissions capture, to reduce carbon and local pollution emissions. Motor fuel taxes should also account for congestion and other externalities associated with vehicle use, at least until...

The International Maritime Organization (IMO) announced in April 2018 a target of cutting greenhouse gas (GHG) emissions from the sector by 50 percent below 2008 levels by 2050 and subsequent meetings of the IMO will develop a strategy for making headway on this commitment. This paper seeks to...

This paper calculates, for the top twenty emitting countries, how much pricing of carbon dioxide (CO2) emissions is in their own national interests due to domestic co-benefits(leaving aside the global climate benefits). On average, nationally efficient prices are substantial, $57.5 per ton of...

The pan-Canadian approach to carbon pricing, announced in October 2016, ensures that carbon pricing applies throughout Canada in 2018, with increasing stringency over time to reduce emissions. Canadian provinces and territories have the flexibility to either implement an explicit price-based...
