The introduction motivates trading fees as a financial-sector service and poses three questions: mechanisms, pricing of liquidity risk, and slow price reversal. It previews the model and its results paragraph by paragraph, claims a methodological contribution (a Walrasian equilibrium concept and a synchronizing algorithm), positions the work against earlier transaction-cost equilibrium papers and dual methods, and ends with a roadmap. The body builds a general model, solves a frictionless benchmark, adds fees with analytical price bounds and the algorithm, then reports numerical illustrations across fee levels. Three applications follow (a CCAPM decomposition, three traders, impulse responses). The conclusion restates the contributions, while appendices hold the setup, FOCs, proof and algorithm details.",245  "writing_profile_keywords": [246   "general equilibrium",247   "trading fees",248   "numerical algorithm",249   "illustrative calibration",250   "comparative statics across fee levels",251   "figure-heavy results",252   "liquidity premia",253   "methodological contribution"254  ],255  "confidence": 0.8,256  "notes": "Classified as theoretical with calibration/simulation as the primary method; the empirical-identification fields are not applicable.
