Relevance

8/10
Highly relevant for quantitative researchers working on high-frequency data, microstructure, and rough volatility. It provides a rigorous microfoundation for inverse-Gaussian clocks used in modeling activity and volatility jumps, bridging microscopic event data with macroscopic stochastic volatility.

Implementation Complexity

9/10
The paper is highly theoretical. Implementing the results requires advanced knowledge of stochastic calculus, branching processes, and Skorokhod topologies. Direct simulation of the limit process is feasible, but deriving the parameters from raw data requires complex statistical estimation of Hawkes kernels.

Reproducibility

5/5
The paper is purely theoretical with complete mathematical proofs provided. Reproducibility involves verifying the mathematical derivations and proofs presented in the text.
