1) Three separate literatures address the consequences of population change. One considers the relation of population change to economic development, for example studies by the National Research Council (1986), Acemoglou and Johnson (2007), Kelley and Schmidt (2005). Another considers the economic consequences of immigration to industrial nations, for example studies by Borjas (2003), Card (2005, 2009). A third considers the economic consequences of population aging, for example Cutler et al, 1990.
a. done
b. Do these literatures focus on similar potential consequences of population change, or on different ones?
c. If you find any differences in focus in your answer to b) are these purely idiosyncratic, or are they related in some logical way to the different sources of population change under consideration?
d. Do these literatures reach conclusions about the economic consequences o population change that are consistent or inconsistent with one another?
e. Are there good reasons for these separate literatures to exist?
