BERKELEY – However bad you think the global economy is today in terms of the business cycle, that is only one lens through which to view the world. In terms of global life expectancy, total world wealth, the overall level of technology, growth prospects in emerging economies, and global income distribution, things look rather good, while on still other dimensions – say, global warming or domestic income inequality and its effects on countries’ social solidarity – they look bad.
Even on the business-cycle dimension, conditions have been far worse in the past than they are today. Consider the Great Depression and the implications of market economies’ inability back then to recover on their own, owing to the burden of long-term unemployment.
But, while we are not at that point today, the Great Depression is no less relevant for us, because it is increasingly likely that long-term unemployment will become a similar impediment to recovery within the next two years.
