This paper proves that maximum growth rate implies zero capital, output and consumption. Growth theory faces the dilemma of zero growth rate or zero output, and is unable to escape the zero trap.

Growth rate models: emphasizing growth rate analysis through growth curve modeling
Journal of Applied Statistics, 2012To emphasize growth rate analysis, we develop a general method to reparametrize growth curve models to analyze rates of growth for a variety of growth trajectories, such as quadratic and exponential growth. The resulting growth rate models are shown to be related to rotations of growth curves.

Estimating Initial Epidemic Growth Rates
Bulletin of Mathematical Biology, 2013The initial exponential growth rate of an epidemic is an important measure of disease spread, and is commonly used to infer the basic reproduction number [Formula: see text]. While modern techniques (e.g., MCMC and particle filtering) for parameter estimation of mechanistic models have gained popularity, maximum likelihood fitting of phenomenological ...

Logistic growth rate functions
Journal of Theoretical Biology, 1968Assuming an S-shaped population or organism size versus time curve and a growth rate law of the form dPdt = constant XPa (P∞−P)b where P is the population or size at any time, t, and P∞ is the limiting population at infinite time, several methods are available for evaluating the exponential pair (a, b).

Nonlinear Analysis: Theory, Methods & Applications, 2009
Consider the linear system \(v' = A(t)v\) that may exhibit a polynomial asymptotic behaviour, where \(A(t)\) is an \(n\times n\) matrix of continuous functions. It is shown that if the solution with \(v(0) = v_0\) satisfies \(\lambda = \sup_{v_0\in R^n}\limsup_{t\to +\infty}\frac{\log\|v(t)\|}{\log t} 0\), there exist constants \(a\geq 0\), \(D>0\) and

One of the key elements by which bacteria adjust their growth rate to match nutrient availability in the diverse environments that they inhabit is rRNA synthesis, which directly regulates the rate of ribosome synthesis by a translational feedback mechanism. Gaal et al.

Determinants of discount rates, capitalisation rates and growth rates
Journal of Property Investment & FinancePurposeThis paper analyses the determinants of key inputs for the explicit discounted cash flow (DCF) or the implicit capitalisation models, namely the discount rates and the capitalisation rates. We also study the factors affecting the implied growth rate of the net operating income (NOI).Design/methodology/approachWe make use of a rich database for ...

If several objects grow with time the one with the highest rate of growth will dominate the rest over time. In this article this is discussed for three cases: when the number of objects is finite, countably infinite and a continuum.

An index of the productive efficiency of plants calculated, not in relation to total dry weight (like RGR), but in relation to total leaf area. An index of leaf efficiency due to G. E. Briggs and co-workers. ULR is synonomous with net assimilation rate NAR, but the former term is older and better.
