This paper investigates the total factor productivity (TFP) performance of NWFP agriculture crop subsector from 1970 to 2004. It identifies the sources of growth of TFP growth and assesses TFP growth changes in agriculture crop sub-sector. Data envelopment analysis (DEA) approach is used to estimate the changes in the production frontier. The Malmquist productivity index has decomposed total fa...

BACKGROUND It is now widely accepted that climate change is occurring as a result of the accumulation of greenhouse gases (GHG) in the atmosphere. With the prospect of a warmer world, increased attention is being devoted to the implications for worker well-being and work performance. OBJECTIVES The 'high occupational temperature health and productivity suppression' (HOTHAPS) programme is a mu...

Structural change is important driver of productivity. Existing decompositions structural rely heavily on the share weights firms. Ideally, one would need a complete census all firms to calculate weights. However, empirical data are often less than ideal. Another limitation that existing switch from industry another mixed with startups and bankrupt To address both these limitations, we develop ...

Lighting-related parameters like visual performance and alertness, together with motivation, are assumed to influence productivity, wherever productivity is related to human performance. To test the impact of lighting level on productivity five case studies were started in 2003 and 2004. Studies have been finalized and a number of conclusions can be drawn. Lighting influences productivity if pr...

BACKGROUND Global climate change is already increasing the average temperature and direct heat exposure in many places around the world. OBJECTIVES To assess the potential impact on occupational health and work capacity for people exposed at work to increasing heat due to climate change. DESIGN A brief review of basic thermal physiology mechanisms, occupational heat exposure guidelines and ...

Productivity growth and efficiency improvements are the major sources of economic development. Pure efficiency, scale efficiency, and technology are basic factors, and rules and regulations and balance are recently known factors affecting the Malmquist productivity index. The index is the most common productivity growth index that uses data envelopment analysis models over multiple time periods...
