In discussions about the recent record-setting economic expansion and the accompanying record-setting bull market in stocks, two factors often receive credit: Federal Reserve interest rate policy and increased productivity. This conjunction naturally raises the question of what interest rate policy is appropriate in the face of changing productivity. Before such a policy question can be answere...

Simple grazing models with two herbivores are used to assess the effects of pasture pests on stability and productivity of continously-growing pastures. Algebraic and graphical methods are also presented for estimating losses from pasture pests at different stocking rates directly, from data on productivity/stocking rate relationships. Pests are considered as competing grazing herbivores and de...

The growth rate of total factor productivity seems to have increased recently, at least in the United States. Higher US productivity growth may justify higher stock market valuations than in the past and thus herald an emerging New Economy. However, the size of the estimated growth rate of total factor productivity depends on an assumption about the factor-augmenting properties of technological...

The paper describes the development of energyintensity at a detailed sectoral level for 14 OECD countries for the period 1970-1997 (distinguishing 13 sectors). The analysis is based on a database that merges energy data from IEA Energy Balances, economic data from the OECD International Sectoral Database and constructed energy prices, using IEA data. We document a number of stylised facts focus...

the paper explores the research productivity of the journal vikalpa for the    period of 2003-2012, which is indexed in the ebsco on-line database. various quality aspects of the 437 research articles published in the period were studied. the study elaborates on various aspects of the journal such as year wise distribution of the articles, growth rate of articles, authorship pattern, and degree...

Background: The protein hormone granulocyte colony-stimulating factor (GCSF) stimulates the production of white blood cells and plays an important role in medical treatment of cancer patients. Methods: An efficient process was developed for heterologous expression of human GCSF in E. coli BL21 (DE3). The feeding rate was adjusted to achieve the maximum attainable specific growth rate under crit...

This paper provides parametric estimates of technical change, e¢ ciency change, economies of scale, and total factor productivity growth for large banks (those with assets in excess of $1 billion) in the United States, over the period from 2000 to 2005. In doing so, we propose a distance function based primal total factor productivity growth index, which is valid under both perfect and imperfec...

[Purpose] The purpose of this study was to investigate the effects of energy expenditure rate on work productivity performance at different levels of production standard time. [Subjects and Methods] Twenty industrial workers performed repetitive tasks at three different levels of production standard time, normal, hard, and very hard. Work productivity and energy expenditure rate were recorded d...

We present results from a field experiment designed to measure the importance of managerial commitment to a contract within a firm that pays its workers piece rates. In the tree planting industry the piece rate paid to workers is determined as a function of the difficulty of the terrain to be planted. During the experiment, firm managers told a crew of tree planters that the piece rate had yet ...
