This paper uses the Luenberger productivity index to evaluate the productivity changes of Greek Life insurance companies between 1994 and 2003, combining operational and financial variables. It is found that the average annual productivity change was about 19% and was due to technological progress, whereas the impact of efficiency was minimal. It seems that deregulation, established by the Thir...

Triple product correlations (TPC’s) involving strange quark spin are elucidated in b → uūs process within the standard model. They arise when light quark masses are nonzero. As the momenta and spins of constituent quarks are related to that of the parent hadron, the quark masses are, however small, important and relevant in TPC studies. At this level the TPC’s of interest are of the form ~ss · ...

We describe new experimental productivity statistics, Dispersion Statistics on Productivity (DiSP), jointly developed and published by the Bureau of Labor (BLS) Census Bureau. measures are critical for understanding economic performance. Official BLS which available major sectors detailed industries, provide information sources aggregate growth. A large body research shows that within-industry ...

Available micro-level data suggest that productivity differences across producers are large and persistent even with the narrowest industry definitions. Both supply and demand side frictions contribute to these differences. This paper further analyzes the relationship between productivity dispersion and the producer size. The US Census of Manufactures reveals significant productivity dispersion...

False bad news about population growth, natural resources, and the environment is published widely in the face of contradictory evidence. For example, the world supply of arable land has actually been increasing, the scarcity of natural resources including food and energy has been decreasing, and basic measures of U.S. environmental quality show positive trends. The aggregate data show no long-...

We propose and analyze a two-country model of endogenous innovation cycles. In autarky, innovation fluctuations in the two countries are decoupled. As the trade cost falls and intra-industry trade rises, they become synchronized. This is because globalization leads to the alignment of innovation incentives across firms based in different countries, as they operate in the increasingly global (he...

The problem of how best to find and exploit essential resources, the quality and locations of which are unknown, is common throughout biology. For plants, the need to grow an efficient root system so as to acquire patchily distributed soil nutrients is typically complicated by competition between plants, and by the costs of maintaining the root system. Simple mechanistic models for root growth ...

This paper contributes to the conflicting international evidence on the impact of information and communication technology (ICT) on labour productivity (LP) growth. We examine the link between ICT intensity and New Zealand s LP growth in 29 industries over the period 1988–2003, and over relevant sub-periods. After deriving an ICT intensity index to classify industries into more ICT intensive an...

The aims of this research were to determine how much influence the independent variables have on dependent variable and identify with dominant work commitment construction project managers. is a that can affect value other variables. influenced by either directly or indirectly. After data collection, method used was analysis using Structural Equation Modeling (SEM) Amos program. results showed ...

Ecological protection approaches are important in achieving sustainable productivity growth agriculture. Based on an unbalanced panel dataset for 2010–2016, we used stochastic frontier analysis-based Malmquist total factor index to estimate change of Swedish crop production and its components (efficiency change, technical scale change). We then examined the effect ecological change. The empiric...
