For some time researchers have known that the relationship between health and the residential mobility of the elderly is not straight forward and changes with age. Attempts to examine this relationship in multi-variate models using cross-sectional data have resulted in contradictory or ambiguous...

Aggregate rates of productivity growth are among the most closely watched indicators of economic performance. They are also among the most difficult to measure accurately. This paper explores the sensitivity of such rates to random measurement error using a simple generic model. The model allows...

Elasticity values calculated at the macro level are biased as estimates of micro elasticities, and vice versa. We derive convenient expressions for aggregation/disaggregation biases in an Almost Ideal Demand System. Using after-tax data we calculate income distribution parameters for seven...
