Abstract

fetched live from OpenAlex

The purpose of this study is to provide an economic foundation for asset price processes and to derive economically motivated time-series models as alternatives to the empirically motivated time-series models The analysis is based on the fact that asset prices are completely determined by the information process and the pricing kernel The information process may be interpreted as characterizing a representative investor’s expectations while the pricing kernel equals the standardised marginal utility function of the representative investor in such an economy For example, the geometric Brownian motion as a model for the behaviour of asset prices implies that the pricing kernel has constant elasticity and that the information process is also governed by a geometric Brownian motion These relationships were explained in Chaps 2 and 3 In Chap 4 the literature was reviewed in the light of these relationships. These keywords were added by machine and not by the authors. This process is experimental and the keywords may be updated as the learning algorithm improves.

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

Not calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
