We augment Henderson, Storeygard, and Weil (2012)'s two-signal model of true income growth with a third signal to overcome its underidentification problem. The additional moment conditions from the third signal help fully identify all model parameters without ad-hoc calibrations of the GDP's...

Chapter 6 from the forthcoming Inclusive Wealth Report 2022 looks at human capital in greater detail, based on the latest human capital estimates from the Inclusive Wealth Report (IWR) project. In the chapter, which is repeated here, the growth of human capital and several of its constituent...

This paper examines the extent to which changes in working-age shares associated with population aging might slow economic growth in upcoming years. We first analyze the economic effects of changing working-age shares in a standard empirical growth model using country panel data from 1950-2015....

Economic growth is typically measured in per capita terms. But social welfare should arguably include the number of people as well as their standard of living. We decompose social welfare growth -- measured in consumption-equivalent (CE) units -- into contributions from rising population and...

How far is the world away from ensuring that every child obtains the basic skills needed to be internationally competitive? And what would accomplishing this mean for world development? Based on the micro data of international and regional achievement tests, we map achievement onto a common...

We document the role of intangible capital in manufacturing firms' substantial contribution to non-manufacturing employment growth from 1977-2019. Exploiting data on firms' "auxiliary" establishments, we develop a novel measure of proprietary in-house knowledge and show that it is associated...

We document a process of rapid tertiarization of the Chinese economy since 2005. The employment and value-added shares of the service sector have increased significantly. Moreover, total factor productivity growth has increased faster in the service sector than in the manufacturing sector....

We extend the conventional Solow growth accounting model to allow innovation to affect consumer welfare directly. Our model is based on Lancaster's New Approach to Consumer Theory, in which there is a separate "consumption technology" that transforms the produced goods, measured at production...

In this paper, I develop a new identification method to solve the problem of simultaneous equations, based on heteroskedasticity of the structural shocks. I show that if the heteroskedasticity can be described as a two-regime process, then the system is just identified under relatively weak...
