To Containers: hip hip...

Free exchange: The humble hero | The Economist

I would have always assumed that the use of shipping containers had been a major innovation for trade, but I had no idea it had been as significant as shown in the above article.  For example:
  It was the brainchild of Malcom McLean, an American trucking magnate. He reckoned that big savings could be had by packing goods in uniform containers that could easily be moved between lorry and ship. When he tallied the costs from the inaugural journey of his first prototype container ship in 1956, he found that they came in at just $0.16 per tonne to load—compared with $5.83 per tonne for loose cargo on a standard ship. Containerisation quickly conquered the world: between 1966 and 1983 the share of countries with container ports rose from about 1% to nearly 90%, coinciding with a take-off in global trade (see chart)....
In 1965 dock labour could move only 1.7 tonnes per hour onto a cargo ship; five years later a container crew could load 30 tonnes per hour (see table). This allowed freight lines to use bigger ships and still slash the time spent in port. The journey time from door to door fell by half and became more consistent. The container also upended a rigid labour force. Falling labour demand reduced dockworkers’ bargaining power and cut the number of strikes. And because containers could be packed and sealed at the factory, losses to theft (and insurance rates) plummeted. Over time all this reshaped global trade. Ports became bigger and their number smaller. More types of goods could be traded economically. Speed and reliability of shipping enabled just-in-time production, which in turn allowed firms to grow leaner and more responsive to markets as even distant suppliers could now provide wares quickly and on schedule. International supply chains also grew more intricate and inclusive.
 And a study claims this:
In a set of 22 industrialised countries containerisation explains a 320% rise in bilateral trade over the first five years after adoption and 790% over 20 years. By comparison, a bilateral free-trade agreement raises trade by 45% over 20 years and GATT membership adds 285%.
I have been impressed by containerisation ever since I saw the automated container straddle carriers at the Port of  Brisbane in 2007.   My post about that trip is here.

Steve, without a doubt, one of the best blog sites on the web. I read it every day, and there are real gems in there. Keep it going.

I live and work in Papua New Guinea and good information can be hard to find here.
