If the Health Impact Fund were to be instituted, a single company would be in charge of a medical product all the way from its conception to the health improvements realized by actual patients. The company would be paid for health impact, and it would have to arrange the entire pipeline in between - all the steps of invention, of clinical testing, of getting marketing approval in many different countries, of wholesalers and retailers and prescriptions and so on - in a holistically optimal way.

What is really nice about the Health Impact Fund is that it is a win-win, something that without much cost to anyone makes a lot of people better off.

It seems far-fetched, even preposterous, to blame the global economic order for the persistence of severe poverty in countries that are ruled by obvious thugs and crooks.

For the present system to work, poor people must be excluded from the innovation, because if they could get access at an affordable price, then affluent people would find ways to buy it cheaply as well - and then the innovator would be poorly rewarded and introductions of new medicines would decline.

I think one big improvement would be if we somehow made it cheaper and easier for developing countries to learn from the sad experience of some of the developed countries, and also from some of the positive experiences we have of building good transportation systems, like high-speed rail.

The bottom quarter of the human population has only three-quarters of one percent of global household income, about one thirty-second of the average income in the world, whereas the people in the top five percent have nine times the average income. So the ratio between the averages in the top five percent and the bottom quarter is somewhere around 300 to one - a huge inequality that also gives you a sense of how easily poverty could be avoided.

You may know that in India now the Tata car is becoming all the rage; you can buy it for one lakh - $2000 dollars - it's very, very cheap. So India seems to be going the route that China went a few years ago and that developing countries all over the world seem to want to follow, namely, to rely on these personal vehicles, which is just an irrational way of organizing transport.
