+\section{Methodology}
+
+
+\subsection{Problem Formalization}
+
+Mathematical formalization of agent-induced pricing distortions. Formal definition of potential loss mechanisms $\alpha D$
+
+We consider a business across time during which we have an evolving vector $p_t \in \Re^N$ where $N$ is the number of products in our catalogue. our price vector is directly dependent on a demand function $q_t$ which we define as a linear method of a price elasticity matrix $B_t$. This is the same setup that Microsoft created in their research.
+
+We gether interaction data from users interacting with a sample platform simulating a hotel/airline which generates interaction distributions $I_t = \{(p_t, q_t^\text{obs}, \pi_t)\}_{t=1}^T$
+
+
+\subsection{Cost of Information Framework}
+
+Mathematical demonstration and validation of the COI and citation backed evidence, and framework overview + show harm to user via other cost distortions. Maybe split into 3.2.1 (COI Theory) and 3.2.2 (Framework Design)
+

+
+High level overview of how it works
+\subsection{Experimental Design}
+Study methodology and approach. Data acquisition strategy. Defined objectives and success criteria. Observable metrics and KPIs
+
+\subsection{Dynamic Pricing Algorithm Analysis}
+Deep dive into how the algorithm works, different kinds and justification for chosen appraoches + agent impact modeling and quantification.
+\subsection{Reinforcement Learning Formulation}
+How do we define the state space, action space and reward function breakdown and algorithm benchmarking.
+POSSIBLY: Expand into full subsections: 3.6.1 (State-Action Space), 3.6.2 (Reward Design), 3.6.3 (Benchmarking)
