At a Pareto efficient allocation (on the Pareto frontier), the marginal rate of substitution is the same for all consumers. A formal statement can be derived by considering a system with m consumers and n goods, and a utility function of each consumer as zi = fi(xi) where is the vector of goods, both for all i. The supply constraint is written for . To optimize this problem, the Lagrangian is used:

where λ and Γ are multipliers.

Taking the partial derivative of the Lagrangian with respect to one good, i, and then taking the partial derivative of the Lagrangian with respect to another good, j, gives the following system of equations:

where ƒx is the marginal utility on ƒ' of x (the partial derivative of ƒ with respect to x).

Bet you wish you'd never asked now.
Ask your lino about it tomorrow. I'm sure he will be able to give you a simple explanation.
The societies of consumption and squandering of material resources are incompatible with the idea of economic growth and a clean planet.

Also called the 80 / 20 law. 80% of worlds wealth is held by 20% of population. In RM 80% of the work is done by 20% of the workforce......possibly. :oops:

80% of complaints probably do come from 20% of customers.

I've just read 20% of Postman's posts and 80% were rubbish.

80 % of bonuses go to less than 20 % of workforce

I'll call that the Parasite principle

It's good to get these types of threads, the ridiculous my manager said bollox, so we can reassure ourselves that while the world is falling apart, Royal Mail managers are still being the low-life C***S they have always been.

The daily grind of having to argue your case with an intellectual pigmy of a line manager is physically and emotionally draining.

It's purely a "should take" measurement not a target that members have to meet.
It was never designed to measure performance.

Sorry fishtank, but what is the difference between
" should take time" and a performance measure.
It's the nueanced distinction we're reduced to making since we agreed to use IWT without getting movement from RM on their unreasonable performance standards first. :arrrghhh

Here you pinky in Welsh :

Ar dyraniad Pareto effeithlon (ar y ffin Pareto), y gyfradd ymylol y cyfnewid yr un fath ar gyfer yr holl ddefnyddwyr. Gall datganiad ffurfiol yn deillio drwy ystyried system gyda defnyddwyr m a nwyddau n, ac un o swyddogaethau gwasanaethau o bob defnyddiwr fel Zi = fi (xi) lle yn y fector o nwyddau, ar gyfer pob i. Mae'r cyfyngiad cyflenwad ei ysgrifennu ar gyfer. Er mwyn gwneud y gorau y broblem hon, mae'r Lagrangian yn cael ei ddefnyddio:

lle λ a Γ yn lluosyddion.

Gan gymryd y deilliad rhannol y Lagrangian mewn perthynas ag un da, i, ac yna cymryd y deilliad rhannol y Lagrangian o ran arall da, j, yn rhoi'r canlynol i'r system o hafaliadau:

lle ƒx yw'r cyfleustod ymylol ar ƒ 'x (deilliad rhannol ƒ mewn perthynas ag x).
