Spending by Singapore-based MasterCard cardholders increased 12.4 percent to USD797.4 million in the first month of the Great Singapore Sale (GSS) this year (31 May to 30 June 2013) compared to the same period last year

Discuss whether increasing consumption expenditure in Singapore is desirable for the economy.

SUGGESTED ANSWER

Explain how an increase in consumption expenditure affects the economy (use AD/AS analysis or Y=AE approach)

• Increase in autonomous consumption à increase in aggregate demand (rightward shift of the AD curve) à possible change in the equilibrium level of national income and general price level.
• Whether an increase in consumption is desirable or otherwise will depend on various factors, e.g. state of the economy, nature of consumption (local or imported goods), and time period.
• Acknowledge that “increasing” consumption refers to a persistent/continuous increase in consumption, and not just a one-time increase or a sharp increase. 

Short run impact (of increasing consumption) on the economy:

• State of the economy
• Singapore in 2009 when economy was below full-employment level à desirable
• At the original level of national output, there is excess capacity and thus unemployed resources. With an increase in consumption, aggregate demand will be greater than national output leading to unplanned inventory depletion.
• The decline in stocks will encourage producers to increase production in the next time period. Firms involved in the production to meet the increase in demand will employ more factors of production. The people employed will then spend part of their income based on their marginal propensity to consume and firms will produce more goods and employ more factors of production. This raises the income of another group of people and so on.
• However, each subsequent round of consumer spending becomes smaller as the increase in income generated becomes smaller. The process will stop when there is no further change in income. The change in national income will be a multiple of the autonomous change in consumption i.e. ∆Y = k.∆C where k is the value of the multiplier. Given that the economy is operating below full-employment, there will be an increase in output with no or little change in the general price level.
• Singapore in 2013 when economy was operating near full-employment level (unemployment rate was 2.1%) à not so desirable
• With the increase in AD, there is increased competition for the limited resources as producers increase output. Factor prices will increase leading to increase in cost of production, illustrated by the movement up along the aggregate supply (AS) curve.

At the same time, higher prices would reduce the level of aggregate demand, illustrated by the movement leftwards along the AD curve. A new equilibrium is reached where the general price level (GPL) and national output are both higher. If the economy is at full employment, the increase in consumption will lead to a sharp increase in the GPL with no change in real national output though nominal output will increase

Topic: Uses of social media

Issue: Whether social media has been used/is being used more for what is trivial or what is important

Context: Global

Keywords: Trivial (having little value or importance), Important (necessary, meaningful, of great value)

1. Social media acts as a form of self-expression and is influencing how we share our personalities. However, there are people who abuse these platforms for their own amusement at the expense of others.
2. Human beings are social creatures, and therefore, are dedicated to creating and participating in “social networks” in order to express and share their ideas. With the rise of the internet, people began satisfying this natural necessity in online communities such as internet forums. However, there are many cases of individuals leaving intentionally annoying messages in order to get attention or simply cause trouble. For instance, Twitter trolls inundated Caroline Criado-Perez with threats of rape after she petitioned for Jane Austen’s image to be on the new £10 note. the Twitter trolls began to target her too. And in the latest twist, several female journalists were sent bomb threats. One motive for trolling, and perhaps one we’re all most familiar with, seems to be simple boredom – too much free time after school, at work, or between jobs. These are the individuals who are trolling to kill a few hours, entertain themselves, and even impress others of a similar mind-set.

2. In this information age, social media is used as an important tool to gather up-to-date information like how thousands used Twitter following the 2011 nuclear disaster in Japan. Nevertheless, social media sites are also buzzing with gossip which some/most users seem to prefer over more important news.
3. In our “join the conversation” culture, it seems as though no “conversation” is deemed too trifling, and though slow news days have been around as long as reporting the news has, social media can make a frenzy out of a single picture. Reporters and commenters alike felt the need to say something about Beyoncé’s hairstyle, which appeared to be a wig with short, choppy bangs. Everyone with an Internet connection was invited to Weigh In: Love It or Leave It!
