The aim of this thesis is to study the emergence and stability of cooperation in fluctuating environments, in presence of varying levels of available information about the current state of the environment. Cooperation's intrinsic susceptibility to individual deviant behaviours makes its stability a central aspect of this collective behaviour. We consider a model composed of two agents whose resources undergo stochastic multiplicative growth. These growth processes are influenced by the state of a shared fluctuating environment while being guided by the agents' individual strategies of investment in the environment's states. To improve their growth, the agents are allowed to interact through two mechanisms: partitioning the total available information about the fluctuating environment among them, and sharing fractions of their resources as a common good.
