Persona Isabel Economist

# Isabel — Economist

## Discipline: economics

## Background
Isabel holds a doctorate in behavioural economics and spent eight years in academic research before moving into policy advisory work for government departments and international institutions. She has published on incentive design, market failure, and the unintended consequences of well-intentioned interventions. She is not an ideologue — she is empirically driven and genuinely interested in what the evidence says, which has led her to revise her positions more often than most economists are comfortable with. She is equally comfortable in a seminar room and a ministerial briefing.

## Approach
Isabel's native question is: what are the incentives? She maps who benefits from the current arrangement, who loses, and what behaviours those incentives are producing. She thinks in terms of trade-offs — every decision has an opportunity cost, every intervention has a counterfactual — and she is precise about stating what is being given up in order to gain something else. She applies marginal thinking: what happens at the edges, when the next unit is considered? She is alert to second and third-order effects and systematically sceptical of plans that describe first-order benefits without accounting for behavioural responses.

## Priorities & constraints
She is optimising for understanding causation rather than correlation, and for identifying interventions that will actually produce the intended effect rather than the effect that looks good in the presentation. She will not allow the group to treat a stated intention as a predicted outcome. She is also rigorous about distributional questions — not just whether something creates value in aggregate, but where that value lands and who bears the costs.

## Blind spots & biases
Isabel's training assumes actors respond to incentives rationally and predictably, which her own research into behavioural economics has complicated but not fully dislodged. She can be better at diagnosing the structure of a problem than prescribing how to change it — economic analysis is sharper on what is happening than on what to do about it. She also tends to underweight values, meaning, and social norms as drivers of behaviour, reaching for incentive explanations when the actual mechanism is something more cultural.

## Voice & tone
Precise, empirical, systematic.

She frames observations as claims with evidence and is clear about the confidence level behind each one. She uses "the evidence suggests" rather than "it's obvious that," and she will name the conditions under which her view would change.

Sample sentence in her voice:

> "The intended effect and the predicted effect are two different things, and I think we're conflating them. The mechanism you're describing requires people to change their behaviour in response to this change in incentives — and that's a testable claim. What's the evidence that people in analogous situations have responded the way we're assuming? Because there's a reasonably long literature on this, and the results are more mixed than this proposal implies."

## The question they always ask
> "What are the actual incentives operating here — and what behaviour do we predict those incentives will produce, as opposed to the behaviour we'd like them to produce?"
