If any of these factors have more of an effect than the OBR has suggested then the Chancellor will find he has far more room for manoeuvre. I suspect that he already knows this: his largest "cuts" in response are either a re-phasing of existing commitments or subject to a review that wont publish until 2018, by which time the picture will be very different.
If you were to believe the commentariat, the recent falls in the pound are a complete disaster. According to many, we are on the edge of an economic abyss. Our country is about to be plunged into financial turmoil. And, worst of all it would seem, our summer holidays abroad have become a bit more expensive...
The mother in western culture in the twenty-first century faces a huge number of obstacles before her in her attempts to frame her life with 'autonomy' and 'self-determination': or, simply put, the right to live and control one's own life. Mothers feel immense social and economic pressure to 'get a job', or feel the strain of 'doing it all' when they do.
The pristine white snow and luxury hotels of the Swiss town of Davos formed the backdrop recently to the annual meeting of the World Economic Forum; the most significant gathering of the planet's foremost economic, business and political brains. Three days of speeches, discussions and dinners that truly have an influence of global proportions...
In today's world, power lies in our political systems and our economies. These two institutions, broadly speaking, control the way we live our lives. They carry huge implications for our freedoms, our human rights and our levels of security - financial and otherwise. Now consider who has the greatest access to, and control over, these institutions. Overwhelmingly, it's men. This is the conclusion drawn by reams of research into gender parity across the globe. Take, for example, the World Economic Forum's new Global Gender Gap Report, which measures the gender gaps in four key areas - health, education, economic participation and political representation.
Imagine you needed to solve the greatest problem facing humanity; a problem that was universally acknowledged and whose solution was an urgent necessity. Most of us would do anything to save a person we love. Surely we would also spend any amount of money, mortgage our futures even, to save the planet, our life-support system, from catastrophic climate change? But with such commitment and devotion comes vulnerability. This is particularly so when it comes to the issue of climate finance.
I'm delighted to have discovered a leaked 'damage limitation' briefing, sent to David Cameron from advisers, ahead of his meeting with Chinese President Xi Jinping this week. The paper gives some useful advice on what Mr Cameron should say to 'extract' himself from a damaging and embarrassing deal involving Chinese finance for nuclear new build...
If David Cameron and George Osborne had been born to single parents living in social housing, perhaps they would look at life differently. Fate saw them born to privilege, but instead of softening their hearts, their good fortune has hardened them and fostered a belief that victimising the less fortunate is a viable social and economic policy.
Certainly, there is a problem. Between 1991 and early 2015, gross government debt rose from 31% to 89% of GDP. The interest charges to finance this debt last year came to £43bn - roughly equal to the total amount spent on primary and secondary education taken together, or our total expenditure on defence.
LEOcoin is already leading the way in demonstrating how a secure, internationally tradable currency, existing outside the financial status quo, can galvanise the SME sector. I see no reason why it cannot radically change the way governments do business too. Once the dam is breached we'll likely look back and wonder how we used to do finance any other way.
The Conservatives should not be complacent, assuming Corbyn will return the UK to the politics of the 1980s. In the great investment debate he has an opportunity to put forward a coherent and distinct growth agenda. The Conservative party should pre-empt this by doing more to end decades of under-investment.
In today's budget, George Osborne sets out a path for the government's fiscal deficit over the next five years. His aim is to get the overall budget into surplus by 2019/20. This is one year later that planned back in March - a welcome smoothing of the path for eliminating the government's deficit. But he may still be moving too fast.
