The April 22nd issue of The Economist has a full page article, titled in the US print edition "Donaldson's difficult idea" http://www.economist.com/news/finance-and-economic...
. Donaldson being Dave Donaldson, very recognizable from his portrait accompanying the article even though I've not seen him in the last 20 years.
Connection to orienteering? When I was doing orange courses on beginning to orienteer, I was running against Dave, a former member of HKF, now DGL, orange being his elite course at the time (Canada used the colour system back then like the US).
Connection to trade? Dave is a leading proponent on how all communities/countries can benefit from expanded trade. Here's an excerpt: "This month the American Economic Association (AEA) chose to honour Mr Donaldson, now at Stanford University, with the John Bates Clark medal, which is awarded annually to a leading economist under the age of 40. He is a deserving winner: his paper on the railroads of the Raj is a particular marvel. But the AEA’s decision is particularly apt given Mr Donaldson’s focus on trade and, more narrowly, on comparative advantage. This counter-intuitive idea was first set out by David Ricardo, a great British political economist, in a book published on April 19th 1817: 200 years ago this week. It is fundamental to Ricardo’s argument that trade is not a zero-sum affair but creates opportunities for mutual gain. Mr Donaldson’s work provides an opportunity to reflect on precisely what that means."
Note that The Economist is not an unbiased source on trade. It was founded to oppose British protectionism.
