The market service share in Western European economies is growing at cost of agriculture and manufacturing. The success of these economies is more and more depending on the success of their service economy. The majority of the jobs, GDP and productivity growth depends on service innovation. The service sector accounts for more than two thirds of deployment and Gross Domestic Product (GDP) and G...

In this article we perform production efficiency analysis for the 40 countries with largest value added by agricultural sector in 2005. Under the assumption of a nonparametric frontier and production observations satisfying a statistical model including both random and inefficiency errors, we estimate an agricultural production function using DEA measures of efficiency with output orientation a...

Abstract: Accurately monitoring workers in some service sector jobs presents distinctive challenges because: (a) workers interact with, and receive utility directly from, heterogeneous clients; and (b) client contributions to output vary dramatically and may be correlated with the same client characteristics that affect worker utility. The selection bias problem this causes is particularly seve...

The application of a service-oriented perspective in the IT sector has become the paradigm, making managers highly aware of the importance of being service oriented and customer focused. In the IT sector, a service-oriented perspective is encompassed in the widespread field of IT Service Management (ITSM). However, while ITSM practitioners are, to a certain degree, becoming aware of the benefit...

This paper exploits the significant positive response of the share of agricultural value added and GDP per capita growth to variations in the international prices for agricultural commodities and rainfall to construct instrumental variables estimates of the causal effect that changes in the size of the agricultural sector and GDP per capita growth have on the urbanization rate for a panel of 41...

This paper investigates the changing relationship between employment and real output in the U.S. economy from 1948 to 2010 both at the aggregate level and at some major industry-grouping levels of disaggregation. Real output is conventionally measured as value added corrected for price inflation, but there are some industries in which no independent measure of value added is possible and existi...
