Measurement & Analysis of Productivity Growth: a Synthesis of Thought

Description: Abstract: Productivity is one of the most important factors influencing our economic well-being. Productivity growth is essential to a higher standard of living and is vital to a sound economic and political environment. However, there has been a slowdown in the growth of productivity in the United States since the mid-1960s. This slowdown has caused concern among policy makers and researchers. Accordingly, several questions persist both in policy and academic circles. Why has productivity been slowing? and What can be done to reverse this trend? The purpose of this report is to address broadly the first of these two questions by surveying and synthesizing the vast literature on the measurement and determinants of productivity. This review is intended to be a source document for those interested in the measurement and analysis of productivity growth. The report is divided into five sections. In the first section, the importance of productivity growth on economic activity is discussed. In the second section, the so called "facts" about patterns of measured productivity growth in the United States are presented. In the third section, the methods currently used for calculating productivity indices are summarized. In the fourth section, the literature related to the determinants of the productivity growth are reviewed. Finally, in the last section, some suggestions are made for future work in this area.

Saving Farm Labor by Harvesting Crops with Live Stock

Description: "Farm labor often may be saved by using livestock to harvest and market part of the crops. By pasturing forage crops, and feeding down grain crops, much labor can be saved. Hay must be secured for winter feeding, and grain for home use and seed, but on many farms a considerable acreage may be turned directly into beef, pork and mutton. Pasturing off the crops also helps to maintain the fertility of the soil without extra labor or expense. The keeping of farm animals furnishes profitable work during the winter when other work is less pressing, and when they require most care. This distributes remunerative labor throughout the year more evenly than otherwise would be possible. This bulletin points out, largely by pictures of actual farm practices, some of the advantages of keeping livestock and of using the hogs, sheep, and beef cattle to help harvest and market farm crops." -- p. 2

Productivity benefits of industrial energy efficiency measures

Description: We review the relationship between energy efficiency improvement measures and productivity in industry. We review over 70 industrial case studies from widely available published databases, followed by an analysis of the representation of productivity benefits in energy modeling. We propose a method to include productivity benefits in the economic assessment of the potential for energy efficiency improvement. The case-study review suggests that energy efficiency investments can provide a significant boost to overall productivity within industry. If this relationship holds, the description of energy-efficient technologies as opportunities for larger productivity improvements has significant implications for conventional economic assessments. The paper explores the implications this change in perspective on the evaluation of energy-efficient technologies for a study of the iron and steel industry in the US. This examination shows that including productivity benefits explicitly in the modeling parameters would double the cost-effective potential for energy efficiency improvement, compared to an analysis excluding those benefits. We provide suggestions for future research in this important area.

The Effects of Different Percentages of Incentive Pay to Base Pay on Work Productivity

Description: This experiment investigated how different percentages of incentive pay affected performance on a number-entering task. It was hypothesized that the critical factor in incentive pay systems was the absolute amount of money that could be earned in an incentive pay paradigm. A counterbalanced single-subject reversal design was employed to examine effects of incentives on performance. Twelve subjects were used in the experiment with three subjects assigned to one of four experimental paradigms. Two of the experimental paradigms incorporated 10% and 100% incentive pay conditions, while the other two experimental paradigms incorporated absolute pay conditions equal to the 10% and 100% incentive pay conditions. Results indicated that similar trends in productivity occurred across subjects in all four experimental paradigms.

Spatial and Temporal Patterns of Areal and Volumetric Phytoplankton Productivity of Lake Texoma

Description: Phytoplankton productivity of Lake Texoma was measured for one year from August 1999 to August 2000 for four stations, using the oxygen change method and laboratory incubation. Mean values of the photosynthetic parameters, PBmax and alphaB ranged from 4.86 to 46.39 mg O2.mg Chl-1.hr-1 for PBmax and 20.06 to 98.96 mg O2.mg Chl-1.E-1.m2 for alphaB. These values were in the range to be expected for a highly turbid, temperate reservoir. Estimated gross annual areal productivity ranged from 594 g C.m2.yr-1 (P.Q. = 1.2), at a station in the Washita River Zone to 753 g C.m2.yr-1 at a station in the Red River Zone, of the reservoir. Gross annual areal productivity at Station 17, in the Main Lake Zone, was 708 g C.m2.yr-1. Gross areal and volumetric productivity showed distinct seasonal variation with Photosynthetically Available Radiation (PAR) and temperature. Trophic status estimated on a station-by-station basis, using net productivity values derived from gross productivity and respiration estimates, was mesotrophic for all the stations, though one station approached eutrophy. Net productivity values ranged from 0.74 to 0.91 g C. m-2.d-1. An algal bioassay conducted at two stations in August 2000, revealed that phosphorus was most likely the nutrient limiting photosynthesis at both these stations, although the more turbid riverine station was primarily light-limited.

Farm Practices That Increase Crop Yields: The Gulf Coast Region

Description: "Gulf Coast region upland soils are ordinarily deficient in nitrogen and need to be supplied with liberal quantities of organic matter if profitable crop yields are to be produced. This condition is most easily and cheaply remedied by growing such legumes as velvet beans, cowpeas, soy beans, bur clover, crimson clover, hairy vetch, and beggar weed, and by carefully utilizing all farm manures, crop residues, and other sources of humus. By a simple readjustment most of the cropping systems followed in this region may be made to include one or more legumes which will increase the supply of nitrogen and humus in the soil and greatly increase crop yields. Systems by means of which crop yields are being increased in the region are discussed in the following pages." -- p. 2

Faculty Research Productivity at Addis Ababa University

Description: This study explores the research productivity of Addis Ababa University (AAU) faculty. AAU was established in 1950 and is the oldest modern higher educational institution in Ethiopia. Recently AAU took steps to transform itself to become a pre-eminent African research university. One of the characteristics of a research university is the focus on the amount of research conducted by the institution's faculty. Academic institutions measure research productivity primarily based on published work. The purpose of this study was to analyze the research productivity of AAU faculty, and to examine the differential predictive effects of individual and environmental variables on faculty research productivity. This quantitative study used a theoretical framework and instrument, Faculty at Work. Four hundred questionnaires were distributed to Addis AAU faculty in person and 298 questionnaires were returned resulting in a 74.5% response rate. After exclusion of 12 cases with missing information, 286 cases (71.5% response rate) were analyzed. Most of the respondents were men (M = 92.1%, F = 7.9%). The average age of AAU faculty was 44. A hierarchical multiple regression was used to examine the ability of six sets of independent variables (sociodemographic, career, self-knowledge, social knowledge, behavior, and environmental response) to predict research productivity (publication output). Results indicated that there are productive researchers at AAU, and the theoretical framework explained 67.6% of the variance in publication output.

An evaluation of two performance pay systems on the productivity of employees in a certified public accounting firm.

Description: This study examined the effects of switching from an incentive pay system solely based on productivity to a scorecard-based incentive pay system. Performance of staff and senior accountants was analyzed across three departments for a two-year baseline and a three-year intervention period. Results showed that percent of charge hour goal remained high during the study. Once the scorecard-based incentive system was implemented, performance on the other line items increased or remained at or above goal levels. Incentive payouts were generally higher under the second incentive plan than under the first for top performers. Possible explanations for data trends, weaknesses of the measures within the scorecard, measure/line item alternatives and implications for future research are also discussed.

A Test For Structural Change In Productivity: A Look At The Internet

Description: It is said that there is a "productivity paradox" existing in the workplace meaning there are no net benefits from information technology spending. This paper attempts to answer the question as to whether there is a need to account for a change in the growth rate of productivity after the Internet was opened up to commercial use. Using the Chow Test for structural change I concluded that there was indeed a positive change in the growth rate of productivity beginning in the early 1990s that can be associated with increasing Internet usage.

Primary Productivity and Community Metabolism in a Small North Central Texas Pond Ecosystem

Description: Rates of primary production and community metabolism were monitored over a one year period using the diurnal oxygen method. Certain physico-chemical parameters were also measured, and autotrophic standing crops were estimated. An in-depth study was made of the phytoplankton community and various diversity indicies were calculated. Simple correlations were run between all parameters measured (biotic and abiotic), and their inter-relationships examined. Multiple linear regression analyses were used to develop equations predictive of production and community metabolism. Bluegreen algae were the dominant phytoplankters with blooms occurring in late summer and fall. Yearly mean production was approximately 21 kcal per meter square per day with a mean photosynthetic efficiency of 1.2 per cent. Of the various parameters measured turbidity and water temperature were most important in determining rates of primary production.

The Role of Emerging Energy-Efficient Technology in PromotingWorkplace Productivity and Health: Final Report

Description: Research into indoor environmental quality (IEQ) and itseffects on health, comfort, and performance of occupants is becoming anincreasing priority as interest in high performance buildings andorganizational productivity advances. Facility managers are interested inIEQ's close relationship to energy use in facilities and employers wantto enhance employee comfort and productivity, reduce absenteeism andhealth costs, and reduce or even eliminate litigation by providingexcellent indoor environments to employees. The increasing interest inthis field as architects, engineers, facility managers, buildinginvestors, health officials, jurists, and the public seek simple andgeneral guidelines on creating safe, healthy, and comfortable indoorenvironment, has put additional pressure on the research community. Inthe last twenty years, IEQresearchers have advanced our understanding ofthe influence of IEQ on health and productivity, but many uncertaintiesremain. Consequently, there is a critical need to expand research in thisfield, particularly research that is highly multidisciplinary. Inaddition, there is a strong need to better communicate knowledgecurrently documented in research publications to building professionalsin order to encourage implementation of designs and practices thatenhance health and productivity. Against this background, the IndoorHealth and Productivity (IHP) project aims to develop a fullerunderstanding of the relationships between physical attributes of theworkplace (e.g. thermal, lighting, ventilation, and air quality) innon-residential and non-industrial buildings and the health andproductivity of occupants. A particular emphasis of the IHP project is toidentify and communicate key research findings, with their practical andpolicy implications, to policymakers, design practitioners, facilitymanagers, construction and energy services companies, and buildinginvestors.The IHP project has a steering committee of sponsors and seniorscientists. Advisory committees are also established for specificefforts. NIST provides an administrative role for some federallysupported efforts, i.e., sponsors provide money to NIST which then fundsthe work. The preferred mode of operation of the IHP Project is to poolmodest amounts of support from multiple sponsors to achieve objectives,with projects selected by the IHP Steering Committee. …
