The acceleration in U.S. total productivity after 1995: the role of information technology

Under standard conditions, total factor productivity (TFP) growth measures the pace of innovation or technological change in the economy. This article focuses on the period since the mid-1990s, when TFP accelerated. The authors find that most of the acceleration is accounted for by industries that use, rather than sectors that produce, information technology.Productivity ; Information technology ; Labor productivity

Growth accounting with misallocation: Or, doing less with more in Singapore

We derive aggregate growth-accounting implications for a two-sector economy with heterogeneous capital subsidies and monopoly power. In this economy, measures of total factor productivity (TFP) growth in terms of quantities (the primal) and real factor prices (the dual) can diverge from each other as well as from true technology growth. These distortions potentially give rise to dynamic reallocation effects that imply that change in technology needs to be measured from the bottom up rather than the top down. We show an example, for Singapore, of how incomplete data can be used to obtain estimates of aggregate and sectoral technology growth as well as reallocation effects. We also apply our framework to reconcile divergent TFP estimates in Singapore and to resolve other empirical puzzles regarding Asian development.Industrial productivity ; Productivity ; Technology ; Singapore

Measuring productivity growth in Asia: do market imperfections matter?

Recent research reports contradictory estimates of productivity growth for the newly industrialized economies (NIEs) of Asia. In particular, estimates using real factor prices find relatively rapid TFP growth; estimates using quantities of inputs and output find relatively low TFP growth. The difference is particularly notable for Singapore, where the difference is about 2-1/4 percentage-points per year. We show that about 2/3 of that difference reflects differences in estimated capital payments. We argue that these differences reflect economically interesting imperfections in output and capital markets, including sizeable economic profits in Singapore and government-directed credit. We derive a measure of technology growth, corrected for the imperfections that we quantify.Asia ; Economic conditions ; Productivity

Measuring the miracle: market imperfections and Asia's growth experience

The newly industrialized economies (NIEs) of Asia are the fastest-growing economies in the world since 1960. A clear understanding of their rapid development remains elusive, with continuing disputes over the roles of technology growth, capital accumulation, and international trade and investment. We reconcile seemingly contradictory explanations by accounting for imperfections in output and capital markets. For instance, in Singapore, growth-accounting studies using quantities (the primal approach) find rising capital-output ratios and a constant labor share; but studies using real factor prices (the dual approach) find a constant user cost. We provide evidence that "favored" firms reaped economic profits and received preferential tax treatment, subsidies, and access to capital-- market imperfections that are difficult to capture when implementing the dual approach. Further, declining pure profits can reconcile the constant or rising labor shares in revenue in the NIEs with theories of international trade that predict falling labor shares in cost. We provide empirical support for the quantitative importance of profits and heterogeneous user costs, describe the two-sector dynamics, and derive measures of technology growth, corrected for the imperfections that we quantify. We then discuss implications for broader disputes about Asian development.Asia ; Economic conditions ; Productivity

Why is productivity procyclical? Why do we care?

Productivity rises in booms and falls in recessions. There are four main explanations for this procyclical productivity: (i) procyclical technology shocks, (ii) widespread imperfect competition and increasing returns, (iii) variable utilization of inputs over the cycle, and (iv) resource reallocations. Recent macroeconomic literature views this stylized fact of procyclical productivity as an essential feature of business cycles because each explanation has important implications for macroeconomic modeling. In this paper, we discuss empirical methods for assessing the importance of these four explanations. We provide microfoundations for our preferred approach of estimating an explicitly first-order approximation to the production function, using a theoretically motivated proxy for utilization. When we implement this approach, we find that variable utilization and resource reallocations are particularly important in explaining procyclical productivity. We also argue that the reallocation effects that we identify are not "biases" -- they reflect changes in an economy’s ability to produce goods and services for final consumption from given primary inputs of capital and labor. Thus, from a normative viewpoint, reallocations are significant for welfare; from a positive viewpoint, they constitute potentially important amplification and propagation mechanisms for macroeconomic modeling.Productivity ; Business cycles
