The current macroeconomic and financial crisis provides quite a natural experiment, much as the oil crisis on the early 1970s did for an older generation. The data will generate many papers in the years to come. One grim aspect to this is that it sheds some light on the macroeconomic determinants of suicide. Brendan & Dermot Walsh have looked at this in the Irish case in a paper published in the Economic and Social Review.
A newspaper article today suggests there has been a recent spike in suicide in Greece. This isn't a scholarly study but then with pressing issues like this, one can't wait for the research to occur before addressing the public policy issues.
