The paper gives conditions for dynamic inefficiency of laissez-faire allocations in an overlapping-generations model with safe and risky assets. If the rate of population growth is certain, the conditions given depend only on how the rate of return on safe assets compares to the growth rate. If...

The paper gives conditions for effi ciency and ineffi ciency of equilibrium allocations in an overlapping-generations model with a constant rate of population growth and with multiple assets, but without labour. Optimal portfolio choice implies that, for any period and history up to that period,...

The paper contributes to the discussion on whether real interest rates smaller than real growth rates can be taken as evidence of dynamic in- efficiency that calls for scal interventions. A seemingly killing objection points to the presence of land, a non-produced durable asset whose value...
