Hardin vs Ostrom: Tragedy of the Commons & CHANS

Garrett Hardin (1968) and Elinor Ostrom (1990) both try to explain how to prevent the tragedy of the commons, especially in coupled human and natural systems (CHANS), where human actions and ecological systems interact. However, they propose very different solutions because they have different views about human behavior and governance.

Two-Stage Dividend Discount Model (DDM)

PQW will pay an annual dividend of 0.65 one year from now. Analysts expect this dividend to grow at 12% per year until the fifth year. After the fifth year, the growth rate will be 2% per year forever. If the firm’s equity cost of capital is 8%, what is the value of a share of PQW stock using the dividend discount model?

Given Data

  • D1 = 0.65
  • g1 (Years 1–5) = 12%
  • g2 (after Year 5) = 2%
  • r = 8%

Step 1: Calculate Dividends for Years 1–5

  • D1 = 0.65
  • D2 = 0.65(1.12)
