Efficiency and utility: an evolutionary perspective

Um artigo interessante e na senda da minha reflexão sobre eficácia vs eficiência e sobre a guerra entre o numerador e o denominador.

"Efficiency and utility: an evolutionary perspective" de Stefan Mann e Henry Wustemann publicado pelo International Journal of Social Economics, Vol. 37 No.9, 2010 pp. 676-685

Do Abstract:
.
"Purpose – The purpose of this paper is to develop the argument that the link between efficiency and utility was strongest in the twentieth century. This would not only explain the growing focus on efficiency in the past, but also suggest that the importance of efficiency in society is set to decrease from now on.
Design/methodology/approach – The two arguments in support of the claim were: first, the growing importance of the service sector where an exaggerated focus on efficiency may decrease utility and second, the utility that is generated by different working environments and identities where heterogeneity is increasing.
Findings – Good reasons are found why the strong correlation between utility and efficiency that could be found in the process of industrialization is loosening."

Do texto, para esclarecer o conceito de utility:
.
"Since, utility is a more basic concept than efficiency, it is worthwhile to begin with the definition of utility which may subsequently be of help in defining efficiency. According to Jevon (1871), utility is the power of a commodity or a service to satisfy human wants."
.
Das conclusões:
.
"The focus of economics on efficiency has, over the decades, contributed to a high standard of living and to a correspondingly high level of utility for billions of consumers.
From a purely consumer perspective, the major importance of efficiency in maintaining or increasing this high level of utility is sustained. However, things take on a different perspective if we leave our consumer role and focus on our role in life wherewe are either members of a social community or part of the workforce.
In the rapidly growing service sector, our identity as social beings plays a far greater role than in the agricultural or industrial sector. This often makes it difficult to define measures of efficiency for services that are clearly linked with the quality of human interaction. Likewise, the growing diversity of working realities increases the importance of the utility (positive and negative) derived from working, so that the measure of efficiency in the professional world becomes less practicable.
.
Efficiency will probably always remain a core concept for production processes, for example in industry, and for a number of other processes in the economic world. However, there are strong arguments for the fact that the concept of efficiency had its most significant impact on society in the twentieth century because the link between societal utility and simple efficiency measures is set to weaken in the future. As economic science is largely defined as a science concerned with efficiency, it is also likely that the importance of economic science as compared to other disciplines will rather decrease."
