Why is there growth in the Romer model?
Paul Romer (1986), Robert Lucas (1988), Sergio Rebelo (1991) and Ortigueira and Santos (1997) omitted technological change; instead, growth in these models is due to indefinite investment in human capital which had a spillover effect on the economy and reduces the diminishing return to capital accumulation.

Firms and individuals are distributed along the unit interval with a total mass of 1, as in Aggregation (and, importantly, there is no population growth). Thus, aggregate investment is, e.g.,
What is the Assumption in the Romer model?
Romer makes the crucial assumption that the effect of the stock of knowledge determines productivity via where η < 1. Thus, suppressing the t subscript, the firm-level Cobb-Douglas production function can be written which is CRS at the firm level in (k,ℓ) holding aggregate knowledge Ξ fixed.
How does the Romer model relate to wages?
Romer’s model contains a full description of the factors that determines the fraction of workers that work in the research section. The research sector gets rewarded with patents that allow it to maintain a monopoly in the product it invents; wages are equated across sectors,
