Market Making With Fads, Informed, and Uninformed Traders
Mathematical Finance, EarlyView.ABSTRACT We characterize the solution to a continuous‐time optimal liquidity provision problem in a market populated by informed and uninformed traders. In our model, the asset price exhibits fads —these are short‐term deviations from the fundamental value of the asset.

A General Class of Exponential Inequalities for Martingales and Ratios
The Annals of Probability, 1999 The author derives several new exponential inequalities for a martingale difference sequence \((d_i,F_i)\), which satisfies either \(E[|d_j|^k\mid F_{j-1}]\leq (k!/2)\sigma^2_j c^{k-2}\) or \(P(|d_j|\leq c\mid F_{j-1})= 1\), for \(k>2\), \(0< c0\), \[ P(M_n\geq x, V^2_n\text{ for some }n)\leq \exp\Biggl\{-{x^2\over 2(y+ cx)}\Biggr\}.

Dam Management in the Era of Climate Change
Mathematical Finance, EarlyView.ABSTRACT Climate change has a dramatic impact, particularly by concentrating rainfall into a few short periods, interspersed with long dry spells. In this context, the role of dams is crucial. We consider the optimal control of a dam, where the water level must neither exceed a designated safety threshold nor fall below a minimum level to ensure ...

Mathematical Finance, EarlyView.ABSTRACT We extend the notion of forward performance criteria to settings with random endowment in incomplete markets. Building on these results, we introduce and develop the novel concept of forward optimized certainty equivalent (forward OCE), which offers a genuinely dynamic valuation mechanism that accommodates progressively adaptive market model ...

Risk Measure Duality Without Structure
Mathematical Finance, EarlyView.ABSTRACT We study risk measures on vector spaces of random variables which a priori have little structure, such as spaces lacking law invariance or a lattice structure. Ensuring the existence of a tractable dual representation (one which does not contain non‐sigma‐additive measures) is one of the main problems in risk measure theory, and we address it ...

Solar Energy Risks: Stochastic Radiation Modeling and Optimal Hedging Strategies
Mathematical Finance, EarlyView.ABSTRACT The growing integration of solar power into electricity markets increasingly demands advanced risk management tools to address the inherent variability of solar radiation and its interaction with electricity prices. This paper introduces a novel framework for modeling and pricing new financial instruments designed to link payoffs directly to ...

Variance Ratio Tests for Panels With Cross‐Section Dependence
Oxford Bulletin of Economics and Statistics, EarlyView.ABSTRACT This paper develops panel variance ratio statistics to examine serial dependence in time series with cross‐sectional dependence. We derive asymptotic properties for panels where the cross‐section dimension N$$ N $$ is fixed or grows with T. Using a factor structure to explain cross‐sectional dependence, we propose a common correlation effects ...

Limit Theorems for Cylindrical Martingale Problems Associated with Lévy Generators [PDF]
Journal of Theoretical Probability, 2019 We prove limit theorems for cylindrical martingale problems associated to Lévy generators. Furthermore, we give sufficient and necessary conditions for the Feller property of well-posed problems with continuous coefficients. We discuss two applications.

With‐Replacement Balanced Sampling
Scandinavian Journal of Statistics, EarlyView.ABSTRACT Balanced sampling ensures that selected samples allow Horvitz–Thompson estimators to reproduce known auxiliary totals. However, no efficient procedures currently exist for producing balanced samples with replacement despite their potential applications to balanced imputations or balanced stream sampling.
