Research published by the Institute for Fiscal Studies shows that ‘Universal Credit will strengthen financial work incentives for some people, as intended, but weaken them for others. In general, incentives to work will be strengthened for the main earner in a family who works part-time or has low earnings, and will be weakened for those with higher earnings and for second earners in couples’ and that ‘moving from the current system of benefits and tax credits to a single benefit will require major administrative and IT changes. It is noteworthy that the government is attempting this at a time when spending on benefit administration (and public service spending generally) is being cut; the fact that such a major reform is being attempted at a time when benefit entitlements are being cut, overall, rather than increased, also increases the political risks to its implementation.
