Warm up Activity Are you ready?
In groups of 3, person will take up a role as: Consumer, Producer Government Are you ready?
3
Warm up Activity For each role, consider the following and share with your peers. Write down the key points on page 1.9 of your lecture notes What do you think is your objective? What are your considerations? e.g. - What are the resources that you will need - Is that anything that you have to give up? We will do a quick sharing after 10 mins.
4
Objective? Constraints Costs and benefits Information Perspective
Consumers considerations Consumers (players) – catch as many pokemons as possible. Complete pokedex. Win battles! – why – happy? Sense of satisfaction? --> maximize utility What are your considerations in playing pokemon? Time taken? (cost? – includes opp cost) Is it Fun? (benefits) Bonding with family/friends? (benefits) Are there better choices? I rather play something else.. Do something else (part of information on cost and benefits of available choices)
5
Producers Objective? Constraints Costs and benefits Information
Perspective Producers considerations What are your considerations ? What are my cost? Monetary cost and opp cost (can resources be better spent in other areas?) What are my revenue earned? – affected by demand and purchase of in-app purchases How to strategise to earn higher profits? Consider consumers’ perspective to come up with strategies Notice that the demand has fallen (changes in external environment) + dangers of playing pokemon ---> decision making process again Other producers – should I buy lures to attract my consumers? How can I tap on this to increase my profits?
6
Objective? Constraints Costs and benefits Information Perspective
Government considerations Does the govt need to intervene? Consider society’s cost and benefit Negative externality? What are your considerations ? What are my cost? Monetary cost and opp cost (can resources be better spent in other areas?) What are my revenue earned? – affected by demand and purchase of in-app purchases How to strategise to earn higher profits? Consider consumers’ perspective to come up with strategies Notice that the demand has fallen (changes in external environment) + dangers of playing pokemon ---> decision making process again

Framework for economic decision making
Theme 1 (chapter 1 focus) Framework for economic decision making
8
Framework of Economic Analysis
In any economy, there are in general 3 economic agents, each with their own objectives: Consumers Maximization of utility Producers Maximization of profit Government Maximization of social welfare Disclaimer: There could be a minority who may not pursue the objectives as stated above…. Ahem…

Framework for Economic Decision-Making
1.8
10
Framework for Economic Decision-Making
Constraints: Scarcity Limited Resources Alternative uses Best-ranked choice 1.8
11
Framework for Economic Decision-Making
Costs and Benefits: Monetary or non-monetary Opportunity cost (to be elaborated) MAXIMIZE NET BENEFIT = Total benefit – total cost 1.8
12
Framework for Economic Decision-Making
Information: Cost and Benefit of available choices Trade-offs / Opportunity cost Intended Consequences 1.9
13
Framework for Economic Decision-Making
Perspectives: Consider perspectives of the other key agents affected by intended outcome Assume rational behaviour Political and Social perspectives 1.9
14
Framework for Economic Decision-Making
Intended Consequences: positive and/ or negative based on the assumptions of rationality and unchanging economic conditions (ceteris paribus) 1.9
15
Framework for Economic Decision-Making
Unintended Consequences: anticipated Decision made under Perfect Information unanticipated Decision made under Imperfect Information 1.9
16
1.5 Framework of Economic Analysis
The decision-making process becomes more complex when decisions change. This occurs when: Intended outcomes are not achieved Adverse unintended consequences arise Changes to the internal and external environment. 1.9
17
1.5 Framework of Economic Analysis
Internal Changes changes in the objectives and the considerations of the decision-making process, i.e. constraints, information and perspectives External Changes changes in the external economic environment 1.9

Scarcity, choice and opportunity cost
Theme 1 chapter 2 Scarcity, choice and opportunity cost
19
Central Problem of Economics (CPE) - Conceptual Framework
Scarcity Unlimited Wants Limited resources Choice What & How much to produce? How to produce? For whom to produce Opportunity Cost
20
2.1.1 Scarcity Definition: Situation where limited resources available are unable to satisfy the unlimited human wants. 2.2
21
Scarcity ≠ Shortage!
22
Who are the top 3 richest people in the world?
23
2.1.1 Scarcity Q - Is there scarcity problem for the super rich?
How about Trump, then? Somewhere in the middle, as it turns out. 324. Donald Trump - $4.2 billion Q - Is there scarcity problem for the super rich? 2.2
24
Scarcity – A “relative” concept!
What does it mean? What are the resources? Unlimited Human Wants Limited Resources Scarcity is a relative concept. Relative to the unlimited wants resources are indeed limited! 2.2
25
What are the (limited) resources?
Think-Pair-Share Land is obvious – remind them that land also covers raw materials (eg some people will say water) But land itself – how do we use it to produce goods that consumers WANT? Then students may say that we need labour, machines (capital) But have we just have these 3 resources, if there are not used, nothing can be produced… so there’s a need for entrepreneurship Ask them to refer to lecture notes while I explain each in detail What are the (limited) resources?
26
2.1.1 (b) Limited Resources Land Labour Capital 2.3
Entrepreneur-ship Land - All natural resources or all productive resources made available to mankind by nature. Labour - Any human effort, both mental and physical, used in the production of goods and services. Capital - Some stock of physical assets (such as tools, instruments and machines) which are man-made to aid in current production. It is not meant for satisfying wants directly but it is used to produce goods which are demanded directly by consumers. So in Economics, capital is not necessarily money it can be physical, human or financial. In this case, we are concerned with physical capital. Entre - The human resource that organizes land, labour and capital in production. Entrepreneurs come up with new ideas about what and how much to produce, make business decisions, and bear risks that arise from these decisions. Without entrepreneurship, virtually no business organisation can operate. 2.3
27
2.1.1 (b) Land Land: all free gifts of nature
Eg. rivers, soil, water, mineral deposits 2.3
28
2.1.1 (b) Labour Labour: human effort, both mental and physical
Quality depends on human capital 2.3
29
2.1.1 (b) Capital Stock of physical assets which are man-made to aid in current production Physical Capital buildings (warehouse, factories), machinery, semi-finished goods. Financial Capital In this case, we are concerned with physical capital. Financial capital is any economic resource measured in terms of money used by entrepreneurs and businesses to buy what they need to make their products or to provide their services to the sector of the economy upon which their operation is based, i.e. retail, corporate, investment banking, etc. Bcos financial capital is not used to produce goods and services, it is not a productive resource. 2.3
30
2.1.1 (b) Entrepreneurship organises other factors of production
Land, labour, capital risk-taking and decision-making Li Hejun, with a net worth of $26 billion Human resources who take risk and innovate Entrepreneurs bring together land, labour and capital in production to make profits Who else?? Jack Ma 2.3
31
BEE Question 4 (p2.5) In pairs/threes: Explain the resource constraints facing our country, Singapore. Key in your answers. We will discuss in about 15 minutes time.
32
Since resources are scarce, how do we allocate the resources?
33
Since resources are scarce, how do we allocate the resources?
SYSTEM What are the 3 Economic systems?
34
Economic System For whom to produce How to produce SCARCITY CHOICE
What & How much to produce How to produce For whom to produce OPPORTUNITY COST Trade offs= having more of one thing mean having less of another 2.1
35
