Abstract

We develop moment estimators for the parameters of affine stochastic volatility models. We first address the challenge of calculating moments for the models by introducing a recursive equation for deriving closed-form expressions for moments of any order. Consequently, we propose our moment estimators. We then establish a central limit theorem for our estimators and derive the explicit formulas for the asymptotic covariance matrix. Finally, we provide numerical results to validate our method.

Complexity vs Empirical Score

  • Math Complexity: 9.0/10
  • Empirical Rigor: 3.0/10
  • Quadrant: Lab Rats — theoretically deep, empirically untested

Why this score: The paper relies heavily on advanced stochastic calculus, recursive moment derivations, and asymptotic theory (central limit theorem), indicating high mathematical complexity. While it includes numerical results for validation, the absence of real-world data backtests, implementation code, or statistical performance metrics (like out-of-sample errors) places it in the theoretical/methodological stage rather than a directly implementable trading strategy.
