➤ How is the utility function written for perfect complements and what does it imply?
Use a Leontief utility like u(x,y)=min(x/α,y/β). This enforces a fixed consumption ratio α:β: extra units of one good add no utility unless the other increases the matching amount. Indifference curves are right-angle kinks, showing perfect complementarity and no willingness to trade one good for another except in fixed proportions.

➤ When will wages differ across industries or occupations in a competitive market?
Wages differ when marginal products, skill requirements, and labor market frictions vary. Industries with higher productivity, scarce skills, or higher product prices tend to pay higher wages. Non-monetary job attributes and barriers like licensing or unions also create persistent wage differences across occupations and regions.

➤ Which of the example values indicate elastic supply?
From the list, 1.70 indicates elastic supply because it exceeds one. 1.00 is unitary elasticity, where percent changes match. 0.70 shows inelastic supply. -0.21 signals an abnormal or measurement issue since supply normally has a positive sign; use absolute values when comparing responsiveness.

➤ When should a plaintiff pursue promissory estoppel rather than a quasi-contract claim?
Pursue promissory estoppel when there is a clear, enforceable promise that induced reasonable reliance and caused loss. Choose quasi-contract when no promise exists but one party received an unfair benefit. Select the theory that best matches the facts to seek reliance damages or restitution respectively, avoiding overlapping recovery.

➤ When are expert witnesses used in mediation?
Parties use expert witnesses in mediation when technical facts, valuation, or specialized injury analysis affect settlement decisions. Experts can prepare reports, meet jointly, or provide private briefings to clarify complex issues. Their role is to inform negotiation and support agreement terms, not to produce the formal testimony required at trial unless the dispute proceeds to court.

➤ How much does a bachelor’s degree reduce the chance of unemployment?
The reduction varies; in many advanced economies bachelor’s holders experience unemployment rates several percentage points lower than high-school graduates. During recessions the gap can widen; in some regions vocational training narrows it. Exact figures depend on country, age group, field of study, and measurement period.
