abstract research and development (r&d;) spending plays a major role in innovation, raising productivity and increasing economic growth. the purpose of this paper is to investigate the impact of r&d; spending on growth and total factor productivity (tfp) in iran's agricultural sector. we estimate growth and productivity models using auto-regressive distributed lag (ardl) approach and data over ...

the purpose of this study is measuring total factor productivity (tfp) growth of sugar beet for different provinces of iran and then decomposing it to the changes in technical change, managerial efficiency change and scale efficiency change. for this purpose we used the data envelopment analysis (dea) method and malmquist productivity index. results showed that average growth of total factor pr...

Legal simplification may improve the quality of institutions in industrialised countries that developed over-complex legal systems. In theory, this type of regulatory reform promotes economic efficiency, leading to higher levels of productivity and output. In this paper we use a Panel Factor-Augmented VAR approach to measure the long-run impact of legal-simplification programmes in total factor...

In this paper the Malmquist index of total factor productivity is applied to a sample of 87 countries observed over the period 1960-90. This index and the method needed to quantify it, the data envelopment analysis, has substantial advantages as compared to traditional growth accounting. Two of these advantages are that it does not rely on questionable equilibrium assumptions to merge multiple ...

The paper analyzes how social barriers to communication affect economy-wide productivity and factor accumulation. Using a dynamic model of an economy that includes a reproducible capital stock (physical or human) and effective labor, a negative relationship is shown to exist between social barriers to communication and total factor productivity (TFP), per capita consumption and reproducible cap...

We study the response of domestic unemployment rates to shocks in total factor productivity for economies with high capital mobility and low labour mobility. We show that high capital mobility amplifies the impact on the domestic unemployment rate of domestic fluctuations in total factor productivity, shortens the lag of the response to shocks and raises the variability of unemployment. But ave...

This paper provides empirical evidence for the interaction between firm-level total factor productivity and trade liberalization as key determinants of firm-level job destruction caused by trade. We also test some key theoretical predictions from Melitz (2003), whose model is used to derive an explicit equation relating firm productivity and trade-induced labor layoff when a country liberalizes...

When we allow capital depreciation to be endogenous, the acceleration of investment-specific technological progress can distort the measurement of the aggregate capital stock. Our quantitative exercise shows that this effect may cause a substantial bias in the measurement of total factor productivity and can account for a large portion of the observed productivity slowdown since the 1970s. 2006...

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 ...
