Economics: Beyond the Pursuit of Money

Economics is about much more than how to earn money. It is a comprehensive discipline that studies how individuals, firms, governments, and societies make choices about allocating scarce resources to satisfy their unlimited wants and needs. The statement "economics is all about how to earn money" oversimplifies the scope and depth of the field of economics.

According to Krugman et al., economics is defined as "the social science that studies the production, distribution, and consumption of goods and services" (2014, p. 2). It examines how individuals, businesses, and governments allocate their limited resources, such as land, labour, capital, and natural resources, to meet their various needs and desires. The primary focus of economics is not merely on earning money but rather on understanding the decision-making processes, incentives, and trade-offs involved in the allocation of scarce resources.

Economics is also defined by well-known nineteenth-century economist Alfred Marshall as "a study of mankind in the ordinary business of life" (Krugman et al., 2014, p. 2). This definition suggests that economics is not solely focused on money-making but rather on understanding how individuals, households, firms, and governments make choices and allocate resources to fulfil their needs and wants.

Krugman et al. (2014) outline twelve fundamental principles that underlie economic analysis, which highlight the breadth and complexity of the discipline. They provide a comprehensive framework for understanding the various aspects of economic behaviour and decision-making processes. These principles can be categorised into three levels: individual choice, the interaction of individual choices, and economy-wide interactions. For reasons of space this essay will focus on the first two levels.

Principles of Individual Choice

At the individual level, the principles emphasize that people must make choices because resources are scarce. This first principle highlights the fact that economics is not just about earning money, but rather about making decisions in the face of constraints.

The true cost of any decision is not just the monetary cost, but also the opportunity cost, which is the value of the next-best alternative that must be given up. This second principle emphasises that economic decision-making involves trade-offs and choices. 

In the third principle individuals often face "how much" decisions, which require marginal analysis. These decisions, such as how much to produce or consume, are made by analysing the marginal costs and benefits of doing a bit more or a bit less.

People also typically respond to incentives, exploiting opportunities to make themselves better off. This fourth principle suggests that economics is not just about earning money, but also about understanding how individuals and firms respond to various incentives and incentive structures.

Principles of Choice Interaction

The fifth principle details how there are gains from trade. Individuals and societies can benefit from trade and specialisation, which allow for the efficient division of labour and the exploitation of comparative advantages.

The sixth principle explains that markets tend to move toward equilibrium because people respond to incentives. Here supply and demand are balanced, and no individual can be made better off by changing their behaviour.

Principles seven and eight show that resources should be used efficiently to achieve society's goals, and markets usually lead to efficiency. Economics is concerned with the efficient allocation of resources, but also with issues of equity and fairness in the distribution of resources and economic outcomes.

The ninth, and final principle detailed in this essay, explains that in cases of market failure, government intervention can improve social welfare. Markets can fail due to individuals taking actions that have external side effects not taken into account by the market. They can also fail due to parties not making mutually beneficial trades and because some goods, such as air traffic control, are unsuited to efficient management by market mechanisms.

These principles demonstrate that economics is not solely about earning money, but rather about understanding the complex interactions and decision-making processes that govern the allocation of scarce resources in society. Economic analysis considers not only monetary gains but also non-monetary costs and benefits, such as time, effort, and overall well-being.

Conclusion

Economics is a rich and multifaceted discipline that extends far beyond the narrow view of simply being "about how to earn money." As demonstrated throughout this essay, economics provides a comprehensive framework for understanding the intricate decisions and interactions that shape how individuals, firms, governments, and societies allocate their limited resources to meet unlimited wants and needs.

At its core, economics is centred on the study of choice and the intricate trade-offs that arise due to scarcity. The principles outlined, such as opportunity cost, marginal analysis, and the role of incentives, illuminate the complexities involved in individual decision-making processes. These principles underscore that economic choices are not solely driven by monetary gain but also by a myriad of factors, including time, effort, well-being, and the pursuit of overall utility maximisation.

Moreover, economics is a discipline that strives to understand the multifaceted and often competing forces that shape human behaviour, resource allocation, and societal well-being. It provides a powerful lens through which to analyse complex real-world phenomena, inform policy decisions, and ultimately promote the efficient and equitable distribution of resources to meet the diverse needs of individuals and society at large.

Reducing economics to merely "how to earn money" fails to capture the depth, breadth, and profound implications of this dynamic and multidimensional field. Economics is a rich tapestry that weaves together individual choices, market forces, government policies, and societal aspirations, all within the constraints of scarce resources and unlimited wants. It is a discipline that transcends the pursuit of wealth and delves into the fundamental question of how to optimally allocate resources to achieve the greatest collective well-being.

Let's Save Africa!

I am going to analyse the SAIH Norway video Let's Save Africa! - Gone Wrong. Ostensibly a satirical work (the YouTube video description states 'We're messing with you'), I hope to argue that this video is in fact promoting discourse opposite to its intention. To do this I am going to use the concepts of contrapuntal reading (Said) and the reality effect (Barthes). Contrapuntal reading is reading with an "awareness both of the metropolitan history that is narrated and of those other histories against which (and together with which) the dominating discourse acts" (Said 51). It also means reading a text "with an understanding of what is involved when an author shows, for instance, that a colonial sugar plantation is seen as important to the process of maintaining a particular style of life in England" (Said 66). With this in mind what follows is my own close contrapuntal reading of the SAIH Norway video. The video starts with Thomas Newman-esque lig...

Jesus Christ

It seems that fairly recently the view that religion is a load of bollocks and is responsible for wars and so on has become very popular.  There is no doubt that there is heart-felt sentiment in support of this view but to dismiss a belief that has been held for over 2,000 years so flippantly was not enough to fully convince me of this standpoint.  I mean, how exactly did Christianity start?  I wanted to find out a bit about it but there was no way I was going to read the bible with its image problems and the fact that it seems to be written in some sort of code, such is the antiquity of the text.  Luckily I managed to find a children’s bible stories book which handily summarised for me most of the writing from the hallowed tome. Upon reading it my reaction was that it was a collection of extremely good stories on the subjects of life and love.  So why have people and, in particular, those in power accepted it as a truthful account of human history and still d...

To what extent do The Matrix and Hayles’ concept of pattern vs presence correlate?

For this essay I am going to close read a section of Chapter 2, Virtual Bodies and Flickering Signifiers from N. Katherine Hayles' book How We Became Posthuman: Virtual Bodies in Cybernetics, Literature, and Informatics. I will then apply her concepts to similar ideas and themes from the 1999 movie The Matrix directed by Lana and Lilly Wachowski. The main interest and purpose of doing this is to see how both works correlate in terms of their conceptions and, due to both works being originally released to the public in 1999, also to see how prescient they were in terms of those ideas today. The section I am going to close read mainly concerns Hayles' conception of pattern vs presence. While Hayles makes the definitions of these two words clear in her writing I want to state them again here at the start along with some of my own definitions for the purposes of my comparison.  Definitions Pattern - computer code, cyberspace as the internet, social media Presence - corpo...
