I find your analysis on growth rate really interesting. Your analysis is based on theories from developmental economics which I have absolutely no knowledge of (actually I have very little knowledge on economics as a whole, its more like a hobby to me). With lack of training in economics, I tried to use engineering theories to interpret your analysis, which I’ve found to be strikingly useful when understanding your analysis. Here is how I break down the analysis:
1. A phenomenon is observed in the real world
2. Numbers and data are collected from the real world
3. Identify important parameters to the phenomenon
4. A model is developed to simulate the real world phenomenon
5. The model is tested using real data to predict the outcome of a similar phenomenon
6. Difference between the model and real world result is compared and corrections are made
7. The model is used to test real data again
8. Repeat step above steps until a satisfactory model has been achieved
Most physical and social phenomenon can be modeled one way or another by the above process and it is also the approach I took in understanding your analysis.
In most engineering problem, the time interval between implementing model and receiving results are usually within a reasonable amount of time and therefore it is possible and practical to develop a so-called optimum model. I could only imagine what a daunting and tedious task it must be is to try to model a social phenomenon as complicated and immense in scale as the growth rate of a country. I guess it would be nearly impossible to consider every single parameters when developing a growth rate model. So what are some of the important parameters you used when plotting the relative growth rate vs. relative capacity graph?
Also, what causes absorbtion rate to decrease as capacity of the catching up country increases? I guess this question would be the same as to ask what Diminishing Marginal Growth Rate is. I tried to think of is as a student raising his grade from 20% to 70% with relative ease while raising from 95% to 100% would require relatively much more work than raising from 20% to 70% grade.
Also on the horsefly example, what is perceived as the growth rate here?
Thanks!
