Proteotyping of laboratory-scale biogas plants reveals multiple steady-states in community composition

Farm-scale Biogas Plants

In Germany there are about fifteen years of experience in the planning and construction of farm-scale biogas plants. In the meantime, approximately 1,600 biogas plants are in operation on farms. This is primarily due to investment funding and payment for each kWh delivered to the public energy grid. In general, three different kinds of digester types are in use for anaerobically treating manure...

Endogenous Productivity and Multiple Steady States

We endogenize total factor productivity in a neoclassical model with increasing returns to scale. We obtain multiple steady-state equilibria with an arbitrarily small degree of increasing returns to scale. While the most productive …rms operate across all the steady states, in a poverty trap less productive …rms operate as well. This results in lower average …rm productivity and total factor pr...
