ECS3704 STUDY GUIDE. In a perfect world - a limited role for government (“order functions”).  In the real world - a more comprehensive role for government. Why? In solving the economic problem the market fails in terms of  efficiency (Ch 2, 3 & 4)  equity (Ch 5)  Allocative efficiency (a normative approach)  measure is Pareto norm - where it is impossible to increase utility/output of one person/sector without reducing that of another,ie, utility (of consumers) is...

Degrees of Freedom - The minimum number of independent coordinates required to completely determine the position of all parts of a system at any point in time. Discrete or Lumped Parameter System - System with a finite number of degrees of freedom. Continuous or Distributed Parameter System - System with an infinite number of degrees of freedom. Free Vibration - :Excitation due to initial conditions, or, equivalently, storedenergy. Forced Vibration - Excitation due to external forces or in...

What are the 3+1 stages of absorption costing? 1. Allocation 2. Apportionment 3. Absorption = Production Cost 4. Under/over = Non prod OH Why would you use Absorption Costing? Valuing Inventory Pricing Decisions Establishing profitability What are pros and cons of absorption and marginal costing? Absorption -Avoids varying profits if sales are seasonal -Consistent with accounting standards -Recognises Long Run variable costs -Implies OH related to production = Manipulate profit ...

Solving Simultaneous Equations: Elimination Method Multiple one, or both, of the equations by suitable multiplier, until they have a matching number of x's or y's 2 variants of method: If the matching terms have one + and one - signs, then use add equations. If signs are the same then subtract equations. Remember: DASS : Different, Add; Same, Substract! Solving Simultaneous Equations: Graphical Method Use if answers are whole numbers. Example: 4x + y = 6 equation(1) 5x-4y = ...
