About this book, GDP and other economic indicators, I think the author wants to tell the readers one important issue that the economic index was built for solving or explaining special problem in the past. For solving these special problems such as unemployment rates or inflation, government developed some indexes by statistics. Although these indexes offer a lot of information to the government, we still need to know these data cannot represent the whole real world because there are many factors that cannot be measured.
Government made policies to establish centers for employees’ training or try to balance between inflation and that economic situation after they get these indexes. Two centuries ago, we didn’t have any indexes could that help government departments or agencies to make decisions. We could imagine that it was like driving a car at night but the lights were not turned on, in the situation, accident could happen easily. Nowadays it is getting better when we get some statistics to help us, just like when we are driving at night and we turn on our headlights that help and guide us drive safely. We can find some problems and adjust our direction if we know that path already deviate the targets. This situation, have indexes that we can review, is better than without any statistical data but we still need to remember that the indexes can’t response one hundred percent fully to our real life. For example, we use GDP index to represent people’s life status but this index can’t guarantee that the people are happy when the GDP is high. Another thing, statistical data must be gotten from measurable factors so we have to ignore some elements if we cannot measure them.
I think the book wants to tell us that we can use new technology to get more useful data and detailed information from people and companies anywhere、anytime by mobile phone、Internet or other portable sensors to improve the data that we need. We also need to consider that there are still some elemental factors that cannot be measured until now. We cannot focus on the statistics alone and ignore invisible factors in this world. Everything is important in our life.
