We show that the welfare of a country's infinitely-lived representative consumer is summarized, to a first order, by total factor productivity and by the capital stock per capita. These variables suffice to calculate welfare changes within a country, as well as welfare differences across...

We show that the welfare of a representative consumer can be related to observable aggregate data. To a first order, the change in welfare is summarized by (the present value of) the Solow productivity residual and by the growth rate of the capital stock per capita. We also show that...

We show that the welfare of a country's infinitely-lived representative consumer is summarized, to a first order, by total factor productivity (TFP) and by the capital stock per capita. These variables suffice to calculate welfare changes within a country, as well as welfare differences across...
