The impediment comes after an initial delay when changes to the visa regime had to be temporarily withdrawn because mandatory public consultation procedures hadn’t been followed. President Cyril Ramaphosa announced his intention to introduce a remote-working visa in his 2022 state-of-the-nation address. “There is just a tax-related matter that needs to be addressed in the regulations,” Leon Schreiber, the country’s Home Affairs Minister, said in a response to queries. “Once that is done, the department will commence with the rollout.” South Africa’s byzantine work permit regime, which means…arrow_forward

- 2. Another issue facing millennials is the growing income and wealth inequality. We will use our model to understand the implications of this issue. A. Begin from the baseline preferences and endowments. Assume Xavier is wealthier than Yuri. Xavier has an endowment of 1100 pounds for each period (E1=E2=1100). Yuri has an endowment of only 900 pounds in each period (E1=E2=900). Note that each period's market supply is unchanged (1100 + 900 = 1000 + 1000 = = 2000).
