but the culture vector is visible to other agents only by its effects on productivity.

$c_j$ is binary, of length, say, $8$.

There is a fixed finite market whose per-turn returns are fixed at unity.

Each firm, $F_k$ is associated with a set $W_k(t)$ of workers at each timestep $t$,

which partition the workforce, i.e. each worker has at most one employer.

We denote by $f(n, t)$ the index of the firm whose

worker set contains $w_n$ at time $t$.

Workers are initially assigned to firms at random with zero wages.

\[R_k = \frac{E_k}{\sum_m E_m}\]

the profitability is income minus expenses, where expenses are assumed to be

comprised only of worker wages.

Firm funds, $\Phi_k$, are given

\[\Phi_k(t) = \sum_{i=1}^t P_k(t) + \Phi_k(0)\] for $\Phi_k(0)$ the startup capital.

We give the knowledge multiplier more simply as the mean of the vector of all

In any case, I'm still nutting out the precise form for it.
