Critics and supporters of the country’s economic liberalisation make the same error–they forget about pollution and population, says Partha Dasgupta, the Frank Ramsey Professor Emeritus of Economics at the University of Cambridge in the Prospect
A central message of modern development economics is the importance of income growth. By this, economists tend to mean growth in gross domestic product, or the market value of what a country produces (including services). In theory, rising GDP creates employment and investment opportunities; and as incomes grow, both citizens and government are increasingly able to set aside funds for the things that make for a good life. One of the tasks of government is to establish conditions that encourage this kind of economic development. Its role should thus be active (protecting the rule of law; investing in infrastructure, health and education) and passive (permitting markets to operate). Of course, GDP growth in itself doesn’t guarantee an equitable distribution of incomes, but that problem can be offset by government taxes and transfers. Or so the argument would have it.
