Speed of production may be an issue in these early days of deployment, but the possibilities for what can be produced with a 3D printer appear to be limited only by the imagination. With chess pieces, cars, small houses and medical equipment being printed, additive technology has certainly earned its considerable attention.

The consensus among analysts is that cheaper oil should be broadly neutral for Latin American countries in general, with clear winners and losers. Their expectation is that net oil exporters will suffer from lower oil prices and net oil importers will benefit. Although we can agree with that general short-term diagnosis, it is predicted that a sustained period of lower oil prices will have a net negative impact on Latin America and on the prospects of U.S. manufacturing companies doing business in the region.

Between 2000 and 2010, the share of the African population living on less than $1.25 per day fell from 58 percent to 48 percent. In no small part, the falling rate of extreme poverty is driven by much-improved output performance.

Few economic entities have been grabbing as many headlines in recent years as the factory. Increasingly human-like robots, self-replicating 3D printers, and software programs that are directing complex supply chains have all been in the news. Reactions have been varied, with some worrying about employment implications and others sensing the possibility of a new era of U.S. industrial might.
