Understanding the complex, dynamic, and non-linear relationships between human activities, the environment and the evolution of the climate is pivotal for policy design and requires appropriate tools. Despite the existence of different attempts to link the economy (or parts of it) to the evolution of the climate, results have often been disappointing and criticized. In this paper, we discuss the use of agent-based modeling for climate policy integrated assessment. 

While the potential adverse effects of fossil fuel subsidy reform are well documented for households, the literature has largely ignored the effect of subsidy reform on firms’ competitiveness. This paper discusses how firms are affected by, and respond to, energy price increases caused by subsidy reforms. It highlights that cost increases (both direct and indirect) do not necessarily reflect competitiveness losses, since firms have various ways to mitigate and pass on price shocks.

The American Recovery and Reinvestment Act included more than $90 billion in strategic clean energy investments intended to promote job creation and promote deployment of low-carbon technologies. In terms of spending, the clean energy package has been described as the nation’s “biggest energy bill in history.” To provide a preliminary assessment of the Recovery Act’s clean energy package, this paper reviews the rationale, design, and implementation of the act.

Demand for renewable energy is booming. Scholars often attribute this success to feed-in tariffs (FITs), which mandate that energy utilities pay a premium to renewable electricity producers and guarantee grid access for them. Why have so many countries, including least-developed ones, adopted these policies? We hypothesize that democratic governments have political incentives to adopt the FIT because it improves environmental quality, promotes rural development, and distributes electricity generation profits from large utilities to independent producers.

This paper presents a macroeconomic model that combines the economic impact of climate change with the pivotal role of private debt. Using a Stock-Flow Consistent approach based on the Lotka–Volterra logic, we couple its nonlinear monetary dynamics of underemployment and income distribution with abatement costs. A calibration of our model at the scale of the world economy enables us to simulate various planetary scenarios.
