I don't think there's any known objective way to measure happiness.

  True in general, but high stress is correlated with un-happiness, and can be objectively measured based on blood cortisol levels (at least for people with normal endocrine systems).

    Good point, but obviously this would be difficult to gather for a large scale study of correlations between income and happiness. If someone's done it, I'd be curious to see the results.
