I believe the answer is: Fear.
Hobbes believed that people would naturally rejects every effort to restrict their full personal freedom to be able to do whatever they want.
The very nature of 'law' itself is to restrict this full freedom in order to maintain a certain level of harmony in a society. Because of this, the people wouldn't follow the law willingly unless there is a punishment for it.

GDP is the total sum of the wealth produced in a country over a given period of time, usually one year. Nominal GDP is GDP at current prices, while nominal GDP is deflated GDP, ie, discounted inflation. Thus, if the inflation rate is 5% = 0.05, we have to use the formula for the real GDP calculation:
Real GDP 2018 = Nominal GDP / 1+ inflation rate
Real GDP = 315 / 1.05 = $ 300 (in billions).
To calculate the GDP growth rate between 2017 and 2018, just narrow the difference between real GDP for both years and divide by the value of real GDP for 2017. The result must be multiplied by 100 to find the percentage value.
GDP growth rate = {(300 - 273) / 273} * 100 = 9.89%
