Explain each of the following topics or terms with examples when specified. Part A: Isocost and Isoquant. 1 Mark Measures the quantity that two factors of production can make. The isocost is the trade of for price similar to a budget line. 1 Mark It shows how many units of each factor (normally labour and capital) can be purchased / employed. 2 mark The isoquant is similar to an indifference curve but instead of showing different ways to generate the same level of happiness it works out the different ways to show how to produce the same level of output. 1 Mark This is used to find the long run paths as well if we consider higher budgets over time. Creating the long run expansion path. Part B: Extensive form games with an example. 1 Mark Games played in sequence. One person moves then the next person moves and so on. 1 Mark What becomes important is what do people know now when they move. 1 Mark This information includes who has moved before them and what have they done. 1 Mark Examples would be Stackelberg leader or firm entry. 1 Mark This is in comparison to normal form games where information is not updated and everyone moves at the same time. Part C: The indifference curve for two goods that are perfect substitutes, explain in words with an example diagram. 1 Mark Straight line downward sloping explains what the trade off is in utility is. 1 Mark Show that the crossing points is when they just get one of the goods to create that utility. 1 Mark Due to the indifference curve being a straight line and budget curves being a straight line the optimal allocation is generally a corner solution where only one good is consumed. 2 Marks for diagram. Part D: budget line including an explanation of its two axis crossing points and the slope. 2 Mark Straight line, crossing points are the maximum amount that can be afforded if all spending goes on that good. (5 Marks) (5 Marks) (5 Marks) (5 Marks) 1 Mark So it is the budget divided by price of that good. The slope of the curve is the price trade off. 2 Mark Anything below the curve is feasible but due to the logic that more is better we generally assume that this line will be a binding constraint unless there is a second constraint (e.g. time). Part E: Asymmetric information. 1 Mark When one side of a deal has more information than the other. Shown in the market for lemons. 1 Mark The key consideration is if and when the lack of information leads to worse outcomes and why. 2 Marks Often it is not the initial manipulation of this information that damages the whole market this is often just a transfer without a loss to the market (we can still view this as bad but it can be solved with other policies) it is normally the person who lacks information assuming they will be manipulated and therefore react to this that damages the market / losses trade. 1 Mark That in the market for lemons complete information and complete misinformation end up with the same outcome it is only asymmetric information that leads to a worse outcome.
Understand the Problem
The question is requesting explanations for several economic concepts, namely isocost, isoquant, extensive form games, indifference curves for perfect substitutes, budget lines, and asymmetric information. Each part needs to include definitions and examples where specified, as well as graphical representations where indicated. The user is likely seeking a comprehensive understanding of these terms within economic theory.
Answer
Part A: Isoquant shows input combinations for equal output; isocost shows cost-equivalent combinations. Part B: Extensive form involves sequential moves like Stackelberg. Part C: Straight-line indifference for substitutes suggests a corner solution. Part D: Budget line's slope is trade-off rate; axis crossings show max affordable goods. Part E: Asymmetric info leads to inefficiency, e.g., market for lemons.
Part A: An isoquant represents different combinations of two inputs that produce the same level of output, while an isocost line represents combinations of inputs that cost the same amount. Part B: Extensive form games are played in sequence, with players making moves one after another. The Stackelberg model is an example. Part C: An indifference curve for perfect substitutes is a straight-line showing different combinations of two goods that provide the same utility. The point where it intersects the budget line indicates optimal consumption. Part D: A budget line illustrates the combinations of goods that can be purchased with a given income, with its slope indicating the rate at which one good can be traded for another. Part E: Asymmetric information occurs when one party in a transaction has more information than the other, often leading to market inefficiencies as demonstrated in the 'market for lemons.'

More Information
Isoquants and isocosts are used in production theory to determine the optimal combination of labor and capital. In game theory, extensive form games help understand strategic decisions over time. Indifference curves for perfect substitutes reflect constant utility derived from goods quantity, leading often to consumption of only one type. Asymmetric information, famously highlighted in the 'market for lemons' problem, results in adverse selection and potential market failure.
Tips
Forgetting that isoquants represent output while isocosts represent cost can lead to confusion. Equating all indifference curves falsely assumes same substitution effects for non-perfect substitutes. Ignoring the sequence in extensive form games misses out on strategic implications.
