Q1 According to United Nations, human population reached 7 billion on October 31, 2011. Using this benchmark and an estimated increase of 3 new persons added to the human population every second (i.e., births – deaths = net increase of 3 p/s), calculate the following: a. On what date (day, month, year) in the future will we reach 8 billion? b. What the population was on the day you were born? c. How long it took for our population to...

Consider the human capital growth model. Let us make the following changes. Depending on whether the current calendar year is an odd or even number, the efficiency parameter of the human capital accumulation technology changes between 5.15 and 2.04. In particular, when the calendar year is an odd number (for example in years 1 and 3) the parameter b is 5.15 and z is 6. However, in even years (for example in years 2 and 4) the parameter is 2.04...
