Morphological productivity is generally seen as affix-driven, with a given affix selecting base words satisfying a range of formal and semantic selectional restrictions. Plag (1999), however, has shown that there are base-driven selectional restrictions, and Hay (2000) and Hay & Baayen (2002) have shown that the frequency relation between derived and base word is correlated with affix productiv...

Productivity is an overall measure of the ability to produce a good or service. More specifically, productivity is the measure of how specified resources are managed to accomplish timely objectives as stated in terms of quantity and quality. Productivity may also be defined as an index that measures output (goods and services) relative to the input (labor, materials, energy, etc., used to produ...

Using a standard definition of productivity growth, it is shown that a country may have higher productivity growth than another country in each sector, but may have a lower productivity growth rate overall. Also, it is shown that popular methods for aggregating firm/industry estimates of productivity growth have a serious problem in that productivity of all firms/industries can go up, but aggre...

This paper investigates the dynamics of Total Factor Productivity at the establishment level. We introduce technology transfer into a framework with heterogeneous firms and ongoing entry and exit. We find evidence that convergence to the frontier is statistically and quantitatively important. Foreign multinationals make up a significant proportion of establishments at the technological frontier...

Among the variables most often tracked by economic analysts and policymakers, the rate of growth of labor productivity is one of the most volatile and hardest to interpret, at least in the short run. Yet, it is often used to explain movements in inflation and output under the assumption that there are stable relationships between productivity growth and those variables. This paper uses frequenc...

of output produced per unit of input. While it is easy to define, it is notoriously difficult to measure, especially in the modern economy. In particular, there are two aspects of productivity that have increasingly defied precise measurement: output and input. Properly measured, output should include not just the number of widgets coming out of a factory, or the lines of code produced by a pro...

Background and Objectives: The purpose of this paper is to suggest a novel method to measure the productivity changes of hospitals over time in the presence of linguistic variables along with fuzzy data. Methods: Applying the popular and applicable approaches including data envelopment analysis (DEA), Malmquist productivity index (MPI) and possibilistic progra...
