Economics 101 (#35) History of Economic Thought

February 7, 2012

Theres an awful lot of revisionism going on lately as governments across the world attempt to battle the economic crisis with competing left and right wing approaches. Conservatives (generally) favour austerity; slashing public spending to get your fiscal house in order (balancing the books) while lowering taxation to promote business growth, entrepreneurship and consumer spending. Liberals (generally) favour government spending or stimuli packages while maintaining (or increasing) tax levels to bring in additional revenue to balance the books while squeezing efficiency out of the current public service, without cutting too deeply (or ‘freezing’ employment). Of course, many countries have adopted a bit of both.

This isn’t a huge surprise. Historically, both doctrines and many halfway house hybrids have had their day, in various forms –  from mercantilism and the classical school to Keynesianism and monetarism, from the 16th century to the 21st. And yes, history tends to repeat itself. Turns out that economics isn’t as predictable  and tamable as some would like to think.

We left the best chapter till last. PIIGSty highly recommends reading it regularly…you’ll definitely need this one (and its a handy conversation starter, at the very least).

Economics 101 (#34) Economics of Population

February 7, 2012

Studying the population is known as demography and, as you probably have guessed, the population/citizens are broken down into categories, known as demographics. This chapter provides a brief overview of the study of population and its component parts, including the all important effects of emigration.

Economics 101 (#33) Economic Development and Growth

February 7, 2012

Right now, most Western economies are at a pivotal point in their histories. You read stories of the BRICs (Brazil, Russia, India, China) and South Africa, as well as several Asian and Latin American ‘tiger’ economies. Economies are all different and grow at different rates depending on their level of development. Like for a child, growth is good but its not continuous – you can grow a lot when you’re a teen, and then stop at 16.

Development is different as it involves a process of maturity and lasting change. For economies, this means society must be significantly changing and the economy is absorbing the growth effectively. Rostow devised an economic model – the ‘5 stages of economic growth‘ which illustrates well the changing structures economies/societies go through.

To be more specific…

But how we know if a country is ‘least developed’ and how can government encourage economic development? Simple really…


Economics 101 (#32) The International Economic System

February 7, 2012

After WW2, a number of international institutions were formed to steamline the flow of trade across borders. It was feared that without agreed and structured intergovernmental bodies independent of political tinkering, European countries would raise their protectionist barriers (tariffs) and seek to keep foreign competition from hurting their own industry (and so, their own people). This marked the formal creation of an international economic system.

Free and unhindered trade was (and remains to be) seen as a vital component for recovering degraded economies. PIIGSty gives you a summary of the 3 main institutions, all of which remain in operation today.

Economics 101 (#31) Balance of Payments

February 6, 2012

International trade can be a profitable enterprise but many rich countries buy far more (in terms of €£$) than they produce thanks to the demands of consumers for highly finished, expensive goods which are produced cheaply in economies with lower costs (lower wage rates, lower cost of raw materials, lower production costs, lower operational costs etc).

A governments main account details the interaction between what it buys and what is sells. This is known as the balance of payments. This details all the financial flows (credit and money)  between a country and its trading partners.

Economics 101 (#30) Currencies and Exchange Rates

February 6, 2012

A currency is essentially like any other good. It follows the law of demand and the law of supply and prices of it adjust accordingly (more abundant, the lower its price/value – the more scarce, the higher its price/value). Currencies facilitate trade because trade needs an established price value of goods. This price is expressed in a local currency i.e. US$, EUR€, GBP£ and others, and it determines demand for a good. As a result, the price of a currency determines demand for what you produce which determines how much you sell (as exports) and how much money you make as an economy. The price of a currency relative to another is called the exchange rate.

A ‘strong’ currency isn’t necessary a good thing….


Economics 101 (#29) International Trade

February 6, 2012

Countries can’t possibly produce everything within their borders they need to keep their citizens happy. The only solution is to produce what you can based on the resources you have and buy all the rest from abroad. Producing everything would mean spreading a country’s resources and labour very thinly and inefficiently (imagine Ireland had to build its own cars, electronics etc).

Like any business, a country focuses on what it can best produce with trade making the whole system operate smoothly. This means Ireland can buy cars from Japan and electronics from the US or China while it focuses on producing agricultural, chemicals, medicines, financial services and all the other things Ireland has an advantage in (whether absolute, or relative vis-à-vis the trading partner in question)

A government, through its resources, has substantial economic power. As such, a government can regulate trade (limiting it, making the country more ‘protectionist’ or promoting it, making the country more ‘open’)
