Linking US demographics with equity markets

August 24, 2011

This blog has mentioned couple of times – ignore demographics at your own peril (see my paper on this).

This new paper from FRBSF econs – Zheng Liu and Mark M. Spiegel – says demographics could lead to lower stock market indices in future. As baby boomers become baby busters, they would be moving away from equity as an asset class leading to its decline.

Two, most big cities end up naturally being in the seismic danger zone. People like to live near water and fertile ground. Over the millennia, seismic activity creates coasts, valleys that channel water, temperate microclimates. So people come and settle at these places and become big cities. As per Claire, 8 of top 10 cities are in seismic zone.

So cities should be working to address this huge risk. And there are some good examples from recent Japanese, NZ and Chilean earthquakes:
