An options-pricing approach to forecasting the US election
A subjective probability argument suggests vote-share estimates from polls can be interpreted as market prices. The corresponding election constitutes the price at a known future date. This makes an options-pricing approach particularly attractive. The approach works well for proportional systems. Here, we show how to adjust the approach for non-proportional first-past-the-post systems. We illustrate our approach with an application to the most recent 2020 and 2024 elections.
期刊介绍:
Many economists today are concerned by the proliferation of journals and the concomitant labyrinth of research to be conquered in order to reach the specific information they require. To combat this tendency, Economics Letters has been conceived and designed outside the realm of the traditional economics journal. As a Letters Journal, it consists of concise communications (letters) that provide a means of rapid and efficient dissemination of new results, models and methods in all fields of economic research.
