Partha Dasgupta on Wealth

An economy’s productive base consists of its capital assets and its institutions. Ecological economists have recently shown that the correct measure of that base is wealth. They have shown, too, that in estimating wealth, not only is the value of manufactured assets to be included (buildings, machinery, roads), but also ‘human’ capital (knowledge, skills health), natural capital (ecosystems, minerals, fossil fuels), and institutions (government, civil society, the rule of law). So development is sustainable as long as an economy’s wealth relative to its population is maintained over time. Adjusting for changes in population size, economic development should be viewed as growth in wealth, not growth in GNP.
