We are halfway through the year (where did the time go?) and it is time to make some predictions about the last half of the year. This week we look at what the leading indicators are telling us, size up a new indicator, drop in on banking data, and do a whole lot more.

Quickly, I will be on Larry Kudlow's show next Tuesday, which is at 7 pm Eastern. Larry has promised that we will spend some quality time on some of the current issues facing us. See you there! And now, let's jump in.

I am on record as saying I think there is a 50-50 chance we slip back into recession in 2011, as I think the economy will soften in the latter half of the year and a large tax increase in 2011 (from the expiring Bush tax cuts) will tip us into recession.

This was not based on data, but rather on research which shows that tax cuts or tax increases have as much as a 3-times multiplier effect on the economy. If you cut taxes by 1% of GDP then you get as much as a 3% boost in the economy. The reverse is true for tax increases. Christina Romer, Obama's head of the Council of Economic Advisors, did the research along with her husband, so this is not a Republican conclusion.

If the economy is growing at less than 2% by the end of the year, then a tax increase of more than 1% of GDP could and probably would be the tipping point. Add in an almost equal amount of state and local tax increases (and spending cuts) and you have the recipe for a full-blown recession - at least the way I see it.

I was asked at my recent speech in Milan, what sorts of things could make me wrong? There are a few. First, it could be that tax increases and cuts don't matter. Some very smart people (like Paul McCulley) feel that tax increases on the wealthy don't really figure into Romer's analysis.

It is not just the US that is in recession. The world is slowing down, and rapidly. This week we quickly survey the rest of the world, and then come back to the US. We follow up with the implications for corporate earnings worldwide, and specifically address my speculations about earnings forecasts for 2009.

Let's start with some charts from my friend Simon Hunt, out of London. The following chart shows World Merchandise Export Values and World Industrial Production falling off a cliff. This is the worst such period since the end of World War II. And as the data we will examine next indicates, it is likely to get worse. Simon notes that consumer spending is about 60% of world GDP, and it is not just in the US that spending is slowing down. Consumers all over the developed world are in shock, as assets such as stocks and houses, real estate, and commodities fall in value. Unemployment is rising.

We think that almost 2,000,000 lost jobs in the last three months in the US is a catastrophe. China lost a reported 20,000,000 jobs in the last quarter, and migrant workers came back to the cities after Chinese New Year to find factories and jobs simply gone. Unemployment is rising rapidly in Europe, as the demand for goods has clearly been falling since last October.
