The Insurance The Customer Sold You: Ski Resorts

A season pass collects the money before the snow falls. On our arithmetic that protects revenue and not margin, because snowmaking rises exactly when visits fall. And the risk is deferred, not transferred.

The Fund You Cannot Reach: Motor Vehicle Dealers

Ontario's dealer compensation fund pays up to $45,000 per transaction. To claim it, the dealer must first be revoked, bankrupt or subject to a judgment. The Auditor General found the criteria miss real harm.

Not Your Money, Not Your Test: Travel Agency Finance

An Ontario travel registrant holds customer money in trust and is measured on a working capital test that is not the one in its own accounts. On our arithmetic the two disagree by enough to turn a pass into a failure.

Two Routes To The Same RevPAR

RevPAR is rate times occupancy, and the two are not equally profitable. On our own arithmetic the same gain is worth $65,000 more through rate. Plus a national benchmark being quoted from the wrong period.

The March Trench: Seasonal Contracting Finance

A seasonal contractor earns twelve months of overhead in seven, and on our own arithmetic the required gross margin does not change at all. What changes is when the cash arrives, and the hole is in March.

Larger Than The Profit: Grocery Shrink

Independent grocery shrink reached 3.9 percent of sales while Canadian net margins run 2 to 4 percent. On our own arithmetic shrink exceeds net profit, and replacing a dollar of it takes $33 of sales.

The Cut Nobody Announced: Money Illusion And Flat Fees

A five percent raise with twelve percent inflation and a seven percent pay cut with none are almost identical in real terms. One feels generous. The other feels like a betrayal.

492 Studies And A Broken Chain: What Changing Implicit Measures Achieves

A network meta-analysis of 492 studies found implicit measures can be changed, that the effects are weak, and that the changes did not carry through to behaviour. Its authors include the field's own leaders.

Slow To Earn, Fast To Lose: Why Good Advice Gets Discounted

People favour their own opinion over advice even when the advice is good. Reputation as an adviser builds slowly and collapses quickly. And confidence rises whether or not the advice is used.

The One-Way Bet: Why Averaging Two Estimates Cannot Lose

If two estimates fall on different sides of the truth, averaging must beat the average judge. If they do not, it ties. People systematically fail to believe this, and a 2006 paper measured how badly.
