The author examines the global impact of U.S. fiscal policy using the Bank of Canadas' Global Economy Model (Lalonde and Muir 2007). In particular, she examines the global macroeconomic implications of the expiration of major tax cuts in the United States and of expected increases in U.S....

The stabilisation of GHG atmospheric concentrations at levels expected to prevent dangerous climate change has become an important, global, long-term objective. It is therefore crucial to identify a cost-effective way to achieve this objective. In this paper we use WITCH, a hybrid...

In recent years, a large number of papers have explored different attempts to endogenise technical change in climate models. The obvious reason is that technical change is widely considered the main route to achieving a significant reduction in global GHG emissions. This recent literature has...

It is widely recognized that technological change has the potential to reduce GHG emissions without compromising economic growth; hence, any better understanding of the process of technological innovation is likely to increase our knowledge of mitigation possibilities and costs. This paper...

Italian presidency in the G20 took place amid uneven economic recovery after the peak of the coronacrisis and building-up of efforts to roll out a large-scale vaccination during new waves of the pandemic. Italian presidency focused on the priorities such as poverty eradication, ensuring of...

Many predictions and conclusions in climate change literature have been made on the basis of theoretical analyses and quantitative models that assume exogenous technological change. One may wonder if those policy prescriptions hold in the more realistic case of endogenously evolving...

There is a long-standing debate on the relationship between economic development and environmental quality. From a sustainable development viewpoint there has been a growing concern that the economic expansion of the world economy will cause irreparable damage to our planet. In the last few...

In this paper we present some numerical simulations with the MacGEM model to evaluate the consequences of the recent Marrakesh agreements and the defection of the USA for the Kyoto Protocol. MacGEM is a global marginal abatement cost model for carbon emissions from fossil fuel use based on the...

Neither income, consumption, nor wealth is an "ideal" tax base, or one that plausibly identifies what one really should want to tax. Rather, they are best justified as imperfect stand-ins for some underlying (but unobservable) metric of inequality that may be relevant to distributive justice...

This paper provides an analysis of the effectiveness of climate policies by focusing on the link between policy options on the one hand, and structure of the agreements and of the international regimes on the other hand. In particular, the paper analyses whether there are the conditions for an...
