The reasons to adopt these definitions are rather mundane. The King - and the ruling elite - can derive their wealth (a) from exploitation or (b) from general productivity growth. The latter is more advantageous in the longer run. [ [4] Productivity can be increased in basically two ways: by technology or by management. For example, computers can add to our wealth, and we must have technology to be able to have computers. But a room full of computers does not present much value if we don’t manage their use. So technology and management are the two sides of the coin of human wealth. Though no study should neglect either side, there of course is advantage in some specialisation of those studies. The engineers take one side, the economists the other.
Psychologists and artists might object to that view, and argue that proper training in enjoyment and in particular the arts could teach people to enjoy life so much more, requiring neither additional engineering nor economics. In a sense, this viewpoint would seem to be correct. In another sense, it apparently isn’t sufficient. Human beings get used to levels of wealth, and require more wealth. It would be economics again to study why people are not happy eating bananas and watching sunsets. And dealing with issues like this, is management again.
Also, when writing this in 2000, and again 2004, there are some rumours about the ‘end of the state’ and the ‘loss of power of existing nation-states’. This clarifies that the definition of ‘Political Economy’ subsequently requires a definition of the ‘state’. I will not try to give that here. [ [5] For the purposes of this book it suffices to take the existing nation-states, and international governmental bodies, and we can reconsider that assumption when they all drop their constitutions.
Then: The economic process can be understood much better if economic policy making itself is included as one of the factors, and then is studied from the Public Choice perspective. The basic proposition of this book hence is that we can extend the current ‘neoclassical synthesis’ by including endogenous government in the model, so that we arrive at a truly general Political Economy.
This extension causes the subsequent proposition that it would be advisable for a democratic society to create an Economic Supreme Court as a separate power in the constitution next to ‘Trias Politica’ of the Legislative, Executive and Judicial branches.
It is useful to recall that economics does not restrict its attention to ‘income’ only, but also considers rights and duties. Coase’s theorem is a good result in an older tradition. Sen (1999)’s “Development as freedom” is a welcome refresher. Beckerman (1999) explains that when economic growth causes our grandchildren to be wealthier than us anyhow, that we should rather focus on bequeathing a good system of justice rather than try for even more growth. So, it is quite natural in Political Economy to also consider the law.
