A distribuição de produtividades está a aumentar

Um dos temas que me fascina, quando penso em produtividade é a sua distribuição dentro de um sector de actividade. Ainda me lembro de ter descoberto que existe mais variabilidade da produtividade dentro de um sector económico de um país, do que entre os diversos sectores económicos de um mesmo país.

Com o finlandês Maliranta descobri aquela citação da coluna do lado direito:

"It is widely believed that restructuring has boosted productivity by displacing low-skilled workers and creating jobs for the high skilled." [Moi ici: Mas, e como isto é profundo] "In essence, creative destruction means that low productivity plants are displaced by high productivity plants."

Agora leio "Productivity Is Soaring at Top Firms and Sluggish Everywhere Else" e recordo porque a produtividade é mais baixa em alguns países:

• Ainda acerca do choque de gestão (Abril de 2015)
• Acerca do choque de gestão (Abril de 2015)

Voltando ao artigo:

"Our research shows that the slow productivity growth of the “average” firm masks the fact that a small cadre of firms are experiencing robust gains. OECD analysis shows that the productivity of the most productive firms – those on the “global productivity frontier” in economic terms - grew steadily at an average 3.5% per year in the manufacturing sector, or double the speed of the average manufacturing firm over the same period. This gap was even more extreme in services. Private, non-financial service sector firms on the productivity frontier saw productivity growth of 5%, eclipsing the 0.3% average growth rate. Perhaps more importantly, the gap between the globally most productive firms and the rest has been increasing over time, especially in the services sector. Some firms clearly “get it” and others don’t, and the divide between the two groups is growing over time."

E em linha com a preocupação da troika em reduzir as barreiras à concorrência interna:

"Seen from this perspective, the productivity problem isn’t a lack of global innovation. It’s a failure by many firms to adopt new technologies and best practices. Indeed, the main source of the productivity slowdown is not a slowing in the rate of innovation by the most globally advanced firms, but rather a slowing of the pace at which innovations spread throughout the economy: a breakdown of the diffusion machine. ... new firms need to be able to enter markets and experiment with new technologies and business models"
