Two schools and the path to the steady state

All of economics is divided into two schools: steady state theory and infinite planet theory. They can’t both be right. You’d think the choice between them would be obvious, but infinite planet theory still holds sway in classrooms and in the halls of power where policy is made. Last month, though, brought a significant development: the manager of a major hedge fund registered a carefully reasoned dissent from infinite planet theory. And in doing so, Jeremy Grantham offered a glimpse of how and why steady state economic theory will ultimately come to prevail.

No nukes, No problem. Germany is proving a rapid transition to renewable energy is possible

Countries around the world are in need of reliable and clean energy. Climate change will require a transition towards a low carbon economy within the next decades. In the wake of Fukushima, the key question is: “If not nuclear, what’s next?” As policy makers and industry stakeholders around the world continue to evaluate the role of nuclear power for energy transition, it will be useful for the US to benchmark its strategies against those of other countries.

Climate, food and and the connectivity paradox

At the most basic level, climate changes that cause world surface temperatures to rise are rooted in increased fossil emissions in the atmosphere. Total fossil fuel emissions are a function of key variables, most notably population, per-capita gross domestic product (GDP) and the carbon intensity of an individual unit of GDP. Understanding these forces and their relationships with each other is critical to measuring the extent of climate change and how we may seek to deal with it.
