For example, it has often been stated that if only fish above a certain size threshold are harvested, then it would become optimal to grow slower (Miller 1957) and mature earlier (Law and Grey 1989).
The main impact of the infectivity being greater than estimated after diagnosis or treatment is that implementing routine testing in acute care settings becomes optimal at a lower cost ratio.
In the model, it becomes optimal for firms to raise future regular pay to maintain workers' current efforts, which results in downwardly rigid regular pay under the threat of performance-based layoffs.
Furthermore, it becomes optimal for firms to base wages less on workers' performance during recessions due to the lower value of productivity.
As sensitivity increases, an adaptive response as seen in Escherichia coli becomes optimal and leads to 'perfect' chemotaxis with a low tumbling time.
In the other extreme, when growth durations are frequently shorter than a limit, a pessimistic strategy becomes optimal: leaving the protected state to resume growth when stress ceases can reduce the long term fitness.
In the limit of no budget increase, Scenario 3 corresponds to Scenario 1 and allocating resources to routine testing in acute care becomes optimal when the cost ratio exceeds approximately 5.5:1.
