Stochastic Dynamic Model on the Consumption – Saving Decision for Adjusting Products and Services Supply According with Consumers` Attainability The recent crisis and turbulences have significantly changed the consumers’ behavior,
especially through its access possibility and satisfaction, but also the new dynamic flexible
adjustment of the supply of goods and services. The access possibility and consumer
satisfaction should be analyzed in a broader context of corporate responsibility, including
financial institutions. This contribution gives an answer to the current situation in Romania
as an emerging country, strongly affected by the global crisis. Empowering producers and
harmonize their interests with the interests of consumers really require a significant revision
of the quantitative models used to study long-term consumption-saving behavior, with a
new model, adapted to the current conditions in Romania in the post-crisis context.
Based on the general idea of the model developed by Hai, Krueger, Postlewaite (2013) we
propose a new way of exploiting the results considering the dynamics of innovative
adaptation based on Brownian motion, but also the integration of the cyclicality concept,
the stochastic shocks analyzed by Lèvy and extensive interaction with capital markets
characterized by higher returns and volatility.
