Arbitrary inflation in fractional models

08/23/2023 12:00 pm 08/23/2023 01:00 pm Australia/Melbourne Arbitrary inflation in fractional models

The analysis of subjective probabilities, that are fractional or share variables by definition, is becoming increasingly widespread in both economics and the social sciences in general.

To avoid nonsensical predictions, empirical predictions for such variables must respect the fact that they are necessarily bounded on the 0-1 (or, 0-100, for percentage-type responses) interval. In addition, where the response variable of interest corresponds to a self-report on a fixed scale, individuals are often drawn to particular focal-point responses, resulting in distinct spikes in the empirical distribution.

In this paper, we suggest a simple model that accounts for all of the nuances of such data, including its fractional and bounded nature as well as arbitrary inflation at such focal-points (which may appear at any point in the interval and are highly likely at the endpoints).

We estimate our model using data drawn from Michigan Health and Retirement Study and the Italian Survey of Income and Wealth relating to an individual's subjective marginal propensity to consume.

He teaches primarily into the econometric streams.

Weekly seminar series

As part of our centre's vibrant research culture, we host a weekly seminar series. Visiting and invited researchers present current research relating to the economics of health and wellbeing, and the healthcare sector. Visitors are welcome to join these sessions where discussion and debate is encouraged.
