This study investigates the relationship between information technology (IT) expenditures and national productivity based on a production estimation approach by using pooled time-series country-level data set for the period from 1992 to 2000. The results confirm the findings of earlier studies on country-level IT investment effect, showing IT to have significant and positive effects on national...

The aim of this study is to investigate the ICT impact on labor productivity growth of EU developing countries. Empirical studies of the role of ICT as one of the main determinants of productivity growth, for developing countries have produced disagreement. To help clear up the subject, this paper employs a Generalized Method of Moments (GMM) through a dynamic panel data approach on the sample ...

A growth model is developed for an open dual economy. Th e economy expands due to a higher growth rate of labour productivity in the modern sector through the Kaldor-Verdoorn channel and higher eff ective demand through a Keynesian channel. Th e model incorporates a retardation mechanism aff ecting the slopes of productivity and output growth schedules as labour surplus and economies of scale d...

limitations of water and nitrogen in soil usually restrict plant growth. the objective of this study was to evaluate the effects of different amounts of supplemental irrigation at different growth stages and application of different rates of nitrogen fertilizer on grain yield and water productivity of wheat cultivars. a field experiment was conducted in the agricultural research station of shah...

We estimate who benefits from local productivity growth. We begin by using confidential plant-level data to calculate changes in manufacturing productivity by United States metropolitan areas (MSAs), and then predict changes in MSA productivity based on MSAs’ initial industry shares and subsequent national changes in productivity by industry. We find that local productivity growth benefits loca...

We analyze a model economy with many agents, each with a different productivity level. Agents divide their time between two activities: producing goods with the production-related knowledge they already have, and interacting with others in search of new, productivity-increasing ideas. Each meeting involves two people, each with a different productivity level. Both parties emerge from a meeting ...

In this paper, we measure productivity growth of the information technology (IT) industries in fourteen OECD countries over the thirteen-year period of 1978 through 1990. The IT industries are the providers of IT capital goods, and this macro-level analysis seeks to find out how efficiently IT capital goods are produced. The basic unit of analysis employed is the Malmquist Total Factor Producti...

a r t i c l e i n f o Using data on 3-digit industry for 1981–2004, the study examines the association between total factor productivity and economic reforms. We first obtain the industry-level productivity numbers using advanced econometric techniques and thereafter ascertain the time frame over which economic reforms impact productivity. The evidence suggests that productivity growth is not r...

this paper tries to measure and analyze the trend of indicators of labor and capital productivity as well as total factor productivity (tfp) in the economic sectors introduced in the 4th five-year-development plan for the period within 1971-2003. according to the results, the productivity indicator throughout iran has increased 0/9% on average annually and the highest growth has been in the tel...

Since 2005, labour productivity growth in Ontario’s business sector has been zero, greatly under-performing the rest of Canada and being single-handedly responsible for most of what has been described as “Canada’s dismal productivity growth.” This article examines the issue through detailed sectoral data, and finds a wide range of variation underlying the average productivity growth rate. Some ...
