Money and Government: The Past and Future of Economics by Robert Skidelsky is a history of political economy and an examination of two schools of economic thought: metalists vs chartilist (put simply). The book examines a history of economic thought within governmnet - mostly focusing on the United Kingdom, where much of modern economics history began, but also looking at the United States, Japan, Germany and France, among others, and how they managed fiscal and monetary policy.
The debate here is interesting - the basic rift between schools of thought seems to split along the lines of how much a government should influence its fiscal and monetary policy. The metalist school of thought, and schools of thought that are based off of it (ie. Austrian), state that a currency should only devolve value from what it is based on. This is obviously based off of the gold or silver standards, which dominated international finance during the age of Imperialism and into the early 20th century. It is a school of thought that promotes fiscal responsibility in times of crisis, and abhors spending ones way out of a crisis. This school of thought is still popular today, with austerity and fiscal prudence - usually attributed to right leaning/conservative politicians. The other school of thought - roughly chartilist, is about deficit spending. Basically, it flows through Keynesian and neo-Keynesian economics. This school roughly considers spending by the government, as well as stronger central banking powers, to be important aspects of managing an economy. Unlike the metalist school of thought, which often promotes prudence and reduced government management, chartilist style economics promotes the opposite. Keynes and his follower (and some would say, disciples) believe in government spending and deficit financing as a means to end economic recessions.
These competing schools are by no means regimented, and each one has its positives and benefits, although Skidelsky shows that often they are politically motivated, over practicality. Too much fiscal prudence can often be cruel to a countries citizens, as governments seek to balance budgets over other important aspects, like feeding people, keeping them employed, and reducing inequality. This can lead to unrest in politics, and disruptive economic forces have seen the collapse of governments, and whole systems of governance, in the past. Fiscal prudence is also accused of short-sightedness, as balancing the budget becomes a means to itself - certainly not the most important thing compared to keeping people from starving or revolting. Fiscal prudence can also lead to stagnation in an economy, as proponents of fiscal prudence often seek to destroy inflation over any other monetary or fiscal consideration. On the other hand, over-spending, although a more medium term solution to problems, can lead to massive amounts of inflation, and as can be seen with the end of Keynesian economics in the 1970's - stagflation. Keynesian economics was proposed as a medium term counterpoint to communist and nationalist forms of economics - a middle road. It promoted some government oversight over economic affairs, while still trying to promote fiscal prudence in some respects. After the fall of communism and nationalism as forms of organization (up until the present, at least) Keynesian economics lost its fighting spirit, and a return to forms of thought largely influenced by the likes of Ricardo, Schumpeter, and other small government economists, became the norm. Even so, this return to fiscal prudence lead to the opposite - rampant deregulation of economic policy globally, and a massive global recession with damaging consequences to economies globally - with effects still present to this day.
Money and Government is essentially an examination of macro-economic policy and the relationship between money, politics and government. Economics, while not the main factor (arguably), is still a very important aspect of government stability, and a key element to the stability of a system of governance or a nation state. The schools of though revolving around this are roughly equivalent to a standard "left-wing" / "right-wing" split, or one that represents people in need vs. one that represents vested interests. Both schools of thought are important, and consideration revolving around democracy, liberalism, humanism, and class struggle are apparent and present within these competing schools. Both sides are also not characterized, necessarily, by black and white style contradictions. Each side can be broken down into various schools of thought, and each school of thought takes elements from others. Economics, it seems, is an idea that has been going through centuries of transformation, but with a core set of ideas that have been considered for many decades - much like politics in general.
Money and Government is an interesting book. It is dense and not necessarily for the layman (a difficult read for me, anyway). It contains descriptors of differing thoughts, as well as the math and statistics to back it up. It is well sourced, well written, and a good intermediate text for those interested in macroeconomic policy, and the relationship between finance, monetary policy, and governance. A good solid read.
