Business, Economics and Commercial Studies Discussion Group May 12 2021, 9:16 amSuppose that a country's inflation rate increases sharply. What happens to the inflation tax on the holders of money? Why is wealth that is held in savings accounts not subject to a change in the inflation tax? Can you think of any way holders of savings accounts are hurt by the increase in the inflation rate?

Business, Economics and Commercial Studies Discussion Group October 15 2020, 10:21 amWhy might uncertainty arise during a period of sustained price rises?
a) Because resource costs will increase
b) Because a redistribution of income process will take place
c) A real reduction in international competitiveness will arise
d) Inflation tends to cause things to be less predictable and this makes planning more difficult October 15 2020, 10:21 am
Business, Economics and Commercial Studies Discussion Group September 30 2020, 11:21 amGood morning mates! Is there someone who understands employment and unemployment? I am trying to answer this question and I have attached the tabel.
Describe the household survey of unemployment and, in the context of the survey, explain what is meant the terms below and give the number or rate of each based on the table below for the following dates-- December 2007; June 2009; and July 2017:
c) not in the labor force
d) the unemployment rate
e) the labor force participation rate
f) the employment rate (employment -population ratio)
g) if the answer for 'e' in 12/07 were the same as in 1/20 and the number of employed in 1/20 remained the same at 158,714,000, how many people would be unemployed in 1/20 and what, therefore, would the unemployment rate be in 1/20? September 30 2020, 11:21 am
Computational and Applied Mathematics Discussion Group September 23 2020, 1:39 amHi pips! Can someone help me with this question:
A particle of mass m moves in R3 under a central force F(r) = −dV/dr , in spherical coordinates, so (x, y, z) = (r cos(φ) sin(θ), r sin(φ) sin(θ), r cos(θ)).
Find the Lagrangian from first principles, in terms of (r, θ, φ) and their time derivatives.
(a) show that h, defined by h = mr2φ˙ sin2(θ) is a constant of the motion.
(b) derive the other two equations of motion. September 23 2020, 1:39 am
