The May 2007 issue of the Journal of Monetary Economics published a paper of mine entitled ‘Investment-Specific Technological Progress and Growth Accounting’ which critiqued the work of Greenwood, Hercowitz and Krusell. I argued that the Greenwood-Hercowitz-Krusell (GHK) model is a special...

Two issues related to mapping a multi-sector model into a reduced-form value-added model are often neglected: the composition of intermediate goods, and the distinction between value added productivity and gross output productivity. We demonstrate their quantitative significance for the case of...

In this paper we develop a two-sector growth model of optimizing agents and apply this model to the data for the purpose of addressing the two interrelated questions that preoccupy the literature on development and growth accounting, namely: (1) What determines sustained growth and (2) What...

In a highly influential and thought provoking study, Hanushek, E.A., and Woessmann, L., (NBER Working Paper No.14633, 2009) provide evidence in favor of a strong causal effect of cognitive skills on growth. To quote: “… the simple premise that improving the schools can produce benefits in...

How big a boost to long run growth can countries expect from the ICT revolution? I use the results of growth accounting and the insights from a two-sector growth model to answer this question. The use of a two-sector rather than a one-sector model is required because of the very rapid rate at...

Convergence concerns poor economies catching up with rich ones. At is- sue is what happens to the cross sectional distribution of economies, not whether a single economy tends towards its own steady state. It is the latter, however, that has preoccupied the traditional approach to con- vergence...

This paper investigates the impact of Information and Communication Technologies (ICT) on growth in an economy, consisting of three sectors, ICT-producing, ICT-using and non-ICT-using. The benefits from ICT come from the falling prices of the ICT-using sector’s good, which is used for the...

Economies at early stages of development are often shaken by abrupt changes in growth rates, whereas in advanced economies growth rates tend to be relatively stable. To explain this pattern, we propose a theory of technological diversification. Production makes use of different input varieties,...

We revisit Western Europe’s record with labor-productivity convergence, and tentatively extrapolate its implications for the future path of Eastern Europe. The poorer Western European countries caught up with the richer ones through both higher rates of physical capital accumulation and...
