In [a recent article](http://krugman.blogs.nytimes.com/2016/10/31/trade-plateaus-wonkish/), Paul Krugman showed these equations:

[![Import share expressed in terms of $\alpha,\,\sigma,\,\tau,\,t$](https://i.sstatic.net/cBPU5.png)](https://i.sstatic.net/cBPU5.png)

Which model is this? What do the symbols denote? Is the first symbol a v or nu?
