One is the fiscal cliff, the combination of spending cuts and tax increases that will automatically occur next year if Congress fails to act. The total size of these changes is such that, should they all take effect and remain in effect for a considerable period, the economy is likely to contract and move back into recession. The second relevant aspect of the federal fiscal outlook is the long-run imbalance between taxes and spending. According to projections by the nonpartisan Congressional Budget Office, the deficit is likely to decline somewhat for a few years, but then move higher, both in dollar terms and as a fraction of GDP. This implies that the outstanding stock of federal debt will increase without bound as a ratio to GDP. This is not a feasible scenario and it cannot persist indefinitely. At some point Congress will have to bring taxes and spending into closer alignment. The set of policy choices that are likely to be considered would affect almost every household or business in a meaningful way. Until a fiscal plan is adopted that is sustainable over the longer run, consumers and businesses will make decisions under a cloud of uncertainty. .. excerpt
