What LAWS90065 covers

The learning path moves from Demand, Supply and Elasticity, through the problems opened by Market Power and Entry Barriers, to the synthesis required in Critical Loss and Behavioural Evidence.

It is positioned as Melbourne Law Masters subject.

The intensive subject moves between legal purpose and economic modelling, requiring the model assumptions and the theory of competitive harm to remain visible in the same answer.

Assessment in LAWS90065 is distributed as follows: Online participation 20%; mid-term exercise 30%; final exercise 50%.

Two current LMS captures conflict on the mid-term word count, so that word count is not stated here.

The operational assessment conditions matter here.

Use the live LMS for the current final-exercise instructions and for any additional examination or operating condition; this guide does not infer an absence from the published task list.

What makes LAWS90065 demanding is concrete: Students must make economic models legally relevant by defining the candidate market, tracing substitution or strategic conduct, and keeping a competitive counterfactual separate from a label such as concentration.

Hurdle status is unknown from the verified course material and must be confirmed in the live LMS.

For enrolment planning, Confirm current prerequisite and enrolment rules in the University of Melbourne Handbook or live enrolment system.

Integrated practice: resolve the changed evidence

Q [11 marks]. Strengthen interbrand competition while retaining an exclusive distribution clause and reassess the likely effect. Develop a response that uses Vertical Agreement, makes the role of Double Marginalisation inspectable, and lets Exclusive Dealing alter the conclusion.
  • 3Fix the case-specific meaning and evidential scale of Vertical Agreement.
  • 3Show the operation or inferential link carried by Double Marginalisation.
  • 3Use Exclusive Dealing to test the strongest plausible alternative.
  • 2Report the answer within this limit: The form of a restraint does not decide its competitive effect; interbrand constraints, market power and entry conditions remain necessary.
The response first fixes Vertical Agreement at the scale stated in the scenario and excludes evidence that belongs to a different object. It then traces Double Marginalisation through the relevant evidence rather than assuming the connection. The comparison supplied by Exclusive Dealing determines whether the initial position remains, narrows or reverses. The final claim stays conditional on this boundary: The form of a restraint does not decide its competitive effect; interbrand constraints, market power and entry conditions remain necessary.
Sia tip — Put the decisive Double Marginalisation evidence beside the first conclusion it changes; use the Exclusive Dealing counter-case to reveal any unsupported leap in chapter 26.
