âGDP is a flawed measure of human welfareâ. GDP has always been a measure of output, not of welfare. Using current prices, it measures the value of goods and services produced for final consumption, private and public, present and future.n a recent paper submitted as evidence to the LSEâs Growth Commission, I consider three common criticisms of GDP as a target of policy and explain why I think they are wrong (Oulton, 2012a): 1  The first criticism is that GDP is hopelessly flawed as a measure of human welfare.
Government failure. Government intervention to resolve market failures can also fail to achieve a socially efficient allocation of resources. Government failure is a situation where government intervention in the economy to correct a market failure creates inefficiency and leads to a misallocation of scarce resources.xcessive bureaucracy is also a potential government failure. This is caused by the public sector when it tries to solve the principal-agent problem. Government must appoint bureaucrats to ensure that its objectives are pursued by the managers of public sector organisations, such as the NHS.
