Chapter 3
Value of Information in Stochastic Environments
Chapter 3 summary
When does extra information create enough decision improvement to be worth using?
This chapter treats information as an economic asset. The question is not whether a signal exists, but whether it changes action quality enough to matter under uncertainty.
Simple visual result
Paired-strip comparisons, treatment-effect summaries, and downside-risk views under signal and no-signal settings
Main contribution
Reframes precision-ag information as a decision asset whose value depends on changed action quality
Data
Paired-strip experimental data, monitored signals, treatment outcomes, and profitability measures
Main logic
Compare outcomes with and without the signal and identify whether the information changes decisions enough to create value
Methods
GAM-based regression, causal forests, quantile views, and treatment-effect interpretation under noisy field conditions.
Why it matters
The chapter shifts the discussion from descriptive information to usable information, which is the real decision problem.
