April 2012Productivity and the Welfare of Nations
with Susanto Basu, Fabio Schiantarelli, Luis Serven: w17971
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 countries. The result holds regardless of the type of production technology and the degree of product market competition. It applies to open economies as well, if TFP is constructed using domestic absorption, instead of gross domestic product, as the measure of output. Welfare relevant TFP needs to be constructed with prices and quantities as perceived by consumers, not firms. Thus, factor shares need to be calculated using after-tax wages and rental rates, and will typically sum to less than one. Th...
December 2009Productivity, Welfare and Reallocation: Theory and Firm-Level Evidence
with Susanto Basu, Fabio Schiantarelli, Luis Serven: w15579
We prove that in a closed economy without distortionary taxation, the welfare of a representative consumer is summarized to a first order by the current and expected future values of the Solow productivity residual in level and by the initial endowment of capital. The equivalence holds if the representative household maximizes utility while taking prices parametrically. This result justifies TFP as the right summary measure of welfare (even in situations where it does not properly measure technology) and makes it possible to calculate the contributions of disaggregated units (industries or firms) to aggregate welfare using readily available TFP data. We show how these results must be modified if the economy is open or if taxes are distortionary. We then compute firm and industry contributi...
