Here's a chart I made in Spring, 2013 (the last data point seems to be 2012, 4th quarter). It shows a particular measure of whether the government is running a surplus (negative numbers on this chart) or a deficit (positive numbers on the chart). I've added the red line at zero to make it easier to distinguish surplus (below the line) from deficit (above the line). The denominator is the nominal potential GDP, so that the more recent numbers don't overwhelm the early ones merely by being the product of a much larger economy with higher prices.
Here's the same chart, produced this evening. The FRED site sets the vertical scale for you in order to accommodate the data, so the lines look quite similar, but I've again added a red line, and some differences are clearly visible. In general, the later line seems to have been shifted upward by a couple of percentage points in the earlier part of the data, and half to a full percentage point in the later.
My earlier data puzzle concerned the nominal GDP and the nominal potential GDP, and because my original chart there only showed the difference between the two, I couldn't tell which of those two data series had changed, only that at least one of them had (either the figures for nominal GDP had been made larger, or the figures for potential GDP had been made smaller).
The charts for this new puzzle also include nominal potential GDP, so the first obvious possibility is that this is the culprit in both, but that actually doesn't fit the facts. Potential GDP is strictly in the denominator here, so making it smaller wouldn't have the effect of shifting everything up. More specifically, if you compare the two charts I've presented here, you can find data points that are negative on the earlier chart and positive on the later one. That means that there has to be a problem in the numerator: government current expenditures are now recorded as larger, or government current receipts are now recorded as smaller.
Either way, it's a new problem, not just another occurrence of the same problem as before.
