When I was in grad school at Penn I was active in two clubs: the real estate club and some tech/entrepreneurship club (I can't remember the exact name). These were two areas that I was interested in and so I wanted to hang out with people who were also interested in these things and I wanted to hear from experienced people who were active in these fields.
At that time, which was before the Great Recession, the real estate club was bigger and more active than the tech club. I think it was something like 3 to 1. But I remember one of my professors telling me that participation across the various clubs generally ebbs and flows. Before the dot-com bubble, the tech club was where you wanted to be. But that asset bubble had burst, and so people had moved onto real estate, which, at that time, was in the midst of creating its own asset bubble.
What we students were effectively doing -- by way of deciding where to spend our time -- was chasing the next hot thing. They were chasing where they thought they'd be able to make the most money coming out of school. There is, of course, nothing wrong with this. The pursuit of profit is fundamental to capitalism. But at the same time, I think it's crucially important to have some conviction.
Right now we are going through another cycle. Real estate was hot last year and it is not right now. Tech was hot last year and it is not right now. NFTs were hot last year and they are not right now. The list goes on. But if you like these things and if you have some conviction, is it really the time to move onto the next club? You may find the opposite to be true. Now is actually the time to ramp up participation.

For a number of years now, urbanists – including myself – have been thinking about “peak car.” And that’s because if you looked at vehicle miles traveled (VMT) in the United States since about 2007, the trend line was more or less flat.
This had us wondering whether or it was simply an outcome of the recession or some sort of broader shift.
Well, if you look at the December 2015 numbers from the U.S. Department of Transportation, VMTs are once again growing. In fact, it’s now above the 2007 “peak.” Compared to December 2014, travel on all roads and streets in December 2015 was up by 4.2% or 10.6 billion vehicle miles traveled.
Here’s the chart:

A lot of this could be because of lower gas prices. But I would be curious to hear your thoughts in the comments about whether or not you think 2007 to 2014 was (1) a recessionary blip or (2) a longer term trend in the making.

Just a few days ago, The Federal Reserve Bank of San Francisco published an interesting research study where they argue that this U.S. housing boom is different than that of the early 2000s.
During the last boom, U.S. home prices peaked in 2006 and then dropped about 30% in the wake of The Great Recession. Since then prices have rebounded – almost to their pre-recession levels. This has some people asking whether this story is headed towards the same ending.
“We find that the increase in U.S. house prices since 2011 differs in significant ways from the mid-2000s housing boom. The prior episode can be described as a credit-fueled bubble in which housing valuation—as measured by the house price-to-rent ratio—and household leverage—as measured by the mortgage debt-to-income ratio—rose together in a self-reinforcing feedback loop. In contrast, the more recent episode exhibits a less-pronounced increase in housing valuation together with an outright decline in household leverage—a pattern that is not suggestive of a credit-fueled bubble.”
