The Sources of Aggregate Productivity Growth
نویسندگان
چکیده
The sources of aggregate productivity growth are explored using detailed data for four-digit U.S. manufacturing industries during 1958-96 and a decomposition formula which allows to quantify the contribution of structural change. Labor productivity as well as total factor productivity are considered and the aggregation is performed with either value-added or employment shares. It is shown that structural change generally works in favor of industries with increasing productivity. This effect is particularly strong in the years since 1990, in hightech industries and in durable goods producing industries. The impact of the computer revolution can be clearly identified. JEL classification: L16, O12, O33, L60

The Sources of Labor Productivity Growth in Norway, South Korea and Iran: A Structural Decomposition Analysis
Abstract In this paper,using a structural decomposition analysis (SDA) and the latest available input-output tables we investigate the sources of labor productivity growth in Norway, South Korea and Iran. Then, the contribution of each source in the growth of labor productivity is discussed. The results show that among six factors, value added coefficient is the most influencing factoracross al...
متن کاملIssues on the International Comparison of Productivity : Theory and Measurement
The purpose of this first section is to present a framework for the measurement of aggregate economic growth in a single country over a given period of time. Sources of growth in output for the economy as a whole can be broken down into the rate of aggregate technical change and the contributions of aggregate capital and labour inputs. In this chapter we construct measures of growth in output, ...
متن کاملMeasuring Aggregate Productivity Growth Using Plant-level Data
We define aggregate productivity growth as the change in aggregate final demand minus the change in the aggregate cost of primary inputs. We show how to aggregate plant-level data to this measure and how to use plant-level data to decompose our measure into technical efficiency and reallocation components. This requires us to confront the “non-neoclassical” features that impact plant-level data...
متن کاملAccounting for the Sources of Growth in the Chinese Economy
Using a newly constructed China Industrial Productivity (CIP) data set, this study adopts the Jorgensonian aggregate production possibility frontier (APPF) framework incorporating Domar weights to account for the industry origin of China’s aggregate growth for the period 1980-2010. We show that 7.14 percentage points of China’s gross domestic product (GDP) growth of 9.16% per annum can be attri...
متن کاملDecomposition of Total Factor Productivity Growth of Pistachio Production in Rafsanjan Region of Iran
The stochastic frontier production model is one of the most used ways to estimate efficiency and productivity. The purpose of this paper was to decompose the sources of total factor productivity (TFP) growth into technological progress, changes in technical efficiency and changes in economies of scale. In this paper, we also used Divisia index in order to estimate production function. A random ...
