This study develops a comprehensive discrete numerical model for option valuation that explicitly incorporates risk preferences, which may deviate from risk neutrality. Unlike the traditional binomial tree models - strictly under the risk-neutral paradigm - our framework embeds a constant...

I propose partial-equilibrium models that describe the dynamics of global wheat and corn markets. These models extend the classic competitive storage framework by incorporating nonstationary variables. They are calibrated using data from Ukraine and key importing and exporting countries. The...

The good choice of hyperparameters is crucial for the successful application of deep learning (DL) networks in order to find accurate solutions or the best parameter in solving partial differential equations (PDEs), that are sensitive to errors in coefficient estimation. For this purpose,...
