LATIHAN SOAL OSN EKONOMI 2026 | PERSIAPAN OSN EKONOMI 2026 PART 2 #ekonomikachannel #osnekonomi

Summary

In this Ekonomika Channel video, viewers are guided through a series of practice questions for the 2026 National Science Olympiad in Economics. The host explains key economic concepts including types of unemployment, profit maximization, cost analysis, dividends, diversification, scarcity, price elasticity, opportunity cost, and market equilibrium. Each question is broken down with clear explanations and examples, helping students understand both theory and practical applications. The video balances educational depth with accessibility, offering step-by-step reasoning that prepares learners for competitive exams while reinforcing foundational economic principles in an engaging and structured manner.

Takeaways

• 😀 The video covers economic practice questions for the OSN Economics 2026 exam.
• 😀 The host encourages viewers to like, subscribe, and share the video to help the channel grow.
• 😀 The discussion begins with a question about unemployment types, with the correct answer being frictional unemployment.
• 😀 Frictional unemployment occurs when a person is actively searching for a job but has not yet found one that matches their skills.
• 😀 Seasonal unemployment is caused by changes in seasons, for example, when durian vendors stop selling during the off-season.
• 😀 Structural unemployment happens when there is a mismatch between skills and job market needs, such as a transition from an agricultural to an industrial economy.
• 😀 Cyclical unemployment is related to economic cycles, such as during a recession when jobs are lost due to economic downturns.
• 😀 Open unemployment refers to individuals who are actively seeking a job but have none.
• 😀 The host explains profit maximization in a perfectly competitive market, emphasizing the relationship between Marginal Revenue (MR) and Marginal Cost (MC).
• 😀 If MR exceeds MC, the producer should increase production; if MC exceeds MR, production should be reduced.
• 😀 The host demonstrates a calculation for price elasticity of demand, concluding that an increase in tax on sugary drinks will lead to a decrease in demand by 200 units.
• 😀 Opportunity cost is explained as the value of the next best alternative that must be sacrificed when making a choice, such as choosing to buy a book instead of going to the movies.
• 😀 The video concludes with an analysis of a market scenario where both demand and supply of avocados increase, leading to ambiguous effects on quantity but a definite rise in price.

Q & A

What type of unemployment does Oki experience and why?

Oki experiences frictional unemployment because he is actively seeking a job that matches his skills but has not yet found one. Frictional unemployment occurs when there is a delay in matching job seekers with suitable job opportunities.

In a perfectly competitive market, if a producer's marginal cost is lower than the market price, what should they do?

The producer should increase production. Profit is maximized when marginal revenue equals marginal cost (MR = MC). If MR > MC, producing additional units increases profit.

If a company has an average cost of 10 and marginal cost of 12, what happens to average cost when output increases?

Average cost will increase. When marginal cost (MC) exceeds average cost (AC), producing more units raises the AC.

What is a dividend and who receives it?

A dividend is a portion of a company's profit distributed to shareholders. It is received by shareholders as a reward for their investment in the company.

What is meant by investment diversification?

Investment diversification means spreading investments across various asset types to reduce risk. It prevents heavy losses if one type of asset underperforms.

What is considered the core economic problem?

The core economic problem is scarcity: the limited availability of resources compared to unlimited human wants. This forces individuals and societies to make choices about resource allocation.

How do you calculate the change in quantity demanded using price elasticity of demand?

The change in quantity demanded (%ΔQ) is calculated using the formula: %ΔQ = ED × %ΔP. For example, if ED = -0.8 and the price increases by 25%, then %ΔQ = -0.8 × 25% = -20%, indicating a decrease in demand.

What is opportunity cost and how is it illustrated in everyday choices?

Opportunity cost is the value of the next best alternative foregone when a choice is made. For example, if someone buys a book instead of going to a movie, the opportunity cost is the enjoyment of watching the movie.

What happens to the price and quantity when demand increases and supply decreases simultaneously?

The price will increase, but the change in quantity is ambiguous. Quantity may rise, fall, or stay the same depending on the magnitude of the shifts in demand and supply.

What distinguishes frictional unemployment from structural and cyclical unemployment?

Frictional unemployment occurs due to temporary job searching or career transitions. Structural unemployment results from a mismatch of skills with market needs, often due to economic changes. Cyclical unemployment occurs because of economic downturns or recessions.
