And once again, national employment in tradables expands no faster than the pace of housing supply growth in highly productive cities. Value added can continue to rise in those cities, however, but much of it is redirected to employment growth in lower productivity non-tradable sectors.
We can draw a line between idea creation, value added, and productive metropolitan areas, but this line does not continue on to employment growth.Now if we focus in on the labour force in a place like Silicon Valley, we see that worker productivity is not uniformly dependent on these spillovers.
Our main findings reveal that Italy was more oriented toward C&T-production activities which generate high value added, whereas Portugal was less productive and relatively more specialized into the production of labor-intensive C&T-goods.
Productive risk is the one assuring value added, but unproductive risk is without value added (investment in mine exploration project includes productive risk of economic type, but attending gambling, for example, where risking one's property to achieve much greater money, is called unproductive risk).
A given country has an increasing returns productive structure if it produces high value added commodities that are technically sophisticated and the reverse holds a decreasing returns economic structure is composed of low value added commodities that are technologically simple.
Moreover, this regional block got more productive, signalizing that also the character of the C&T-goods which sourced from these two countries did change and C&T-production activities became slightly more value added generating and less labor-intensive.
But then Silicon Valley has the most productive manufacturing employees in America, each accounting for some $114,000 of value added in 1992 (the latest figure available).The present boom in Silicon Valley seems to be spreading even to its support services.
Economic value added or EVA.
Where is the value added?
Yet, those C&T-production activities which are 'highly' productive and generate high C&T-value added could be maintained relatively more easily.
