Econ 1740: Econ Coursework On Malthusian Model (Coursework Sample)
What does the Malthusian model assume about the relationship between income per capita and CBR (positively related, negatively related, or not related at all)? And between income per capita and CDR? And between population and income per capita? How can the relationship between population and income per capita be explained in the context of an agrarian economy and the land/labor ratio?source..
Course: Econ 1740
1). What does the Malthusian model assume about the relationship between income per capita and CBR (positively related, negatively related, or not related at all)? And between income per capita and CDR? And between population and income per capita? How can the relationship between population and income per capita be explained in the context of an agrarian economy and the land/labor ratio?
The relationship between income per capita and CBR is positively related while the relationship between income per capita and CDR is negatively related. Population growth is correlated positively with the income per capita, but population growth will reduce income over time and the population growth will halt (Persson and Sharp 50). There will be no prospect for sustained growth where population increase the land available for agriculture per head will reduce because of diminishing returns resulting to falling income and subsistence income associated with the stagnating population.
2) Imagine that a society is characterized by the Malthusian logic depicted below. If initially, a population is equal to 3,250 what is the resulting income per capita? And the crude birth rate and the crude death rates that result from that income per capita? Given your previous results, what will happen to the population in the next periods (remember: we assume there is no migration so all the changes in population come from differences between CBR and CDR)? When will that increase or decrease in the population stop? What will be the final size of the population, income per capita, and crude birth and death rates after the adjustment ends?
The resulting income per capita=350
The crude birth rate=25
The crude death rates =35
The birth rate will continue increasing while the death rate will decrease at a point where there is an equilibrium between the two there is no population change there is above subsistence income and positive population growth and an increase in the rate of technological progress increases the income per head. The decrease in population will stop when the crude birth rates are equal to the crude death rates.
The population is 2,500
Income per capita is $500
Crude birth rate is 30
Death rate is 30
3) Now assume that population is equal to 2,500. If technology improves and, consequently, the technology schedule shifts from TS1 to TS2 (see graphs below), how does income per capita change if, initially, population remains at 2,500? What is the crude birth rates and the crude will happen to the population in the next period: will it increase or decrease? When will that process stop? What will be the size of the population, the income per capita, and the crude birth and death rates after the adjustment ends? Compare those results with the initial situation in
