‘Mauritius declared a "state of environmental emergency" on August 7, 2020 after Japanese-owned cargo ship MV Wakashio ran aground on a coral reef, leaking 1,000 tons of oil onto pristine coasts. The island blue economy became a trash economy overnight. The oil from the ship threatens sea life already imperiled by climate change. In the same vein, according to marine ecologist from Mauritius, Fishermen community too, will suffer the consequences for years to come. This devastating oil spill has even poisoned fish and can even make humans sick if consumed.
In a similar way, it also deepens wounds in a tourism industry hurting from the pandemic. In fact, tourism provides jobs for an estimated 1 in 5 of its workers.
But the industry collapsed after the government cut the island off from the rest of the world to protect it from the corona virus pandemic. For shuttered hotels and restaurants, an ecological disaster on top of that might now be too much to bear.
Use appropriate supply and demand diagrams to analyse the effects on the market equilibrium price and quantity traded of fish, following:
Price elasticity of demand (PED) & Income Elasticity of demand (YED) is an important tool for private firms. It helps in decision making.
(a) Explain how a Hotel manager can use the concept of price elasticity of demand and income elasticity of demand in this low season.
(b) Evaluate economic policies that the government of Mauritius can adopt to increase economic growth.

Case 2: Emily, an attractive 23-year-old secretary works for Cover-the-Earth Enterprises, a regional sales company employing over 200 employees. In late 2017, Emily is reassigned to work for Dan, a 60-year-old district sales manager. Dan often makes joking remarks to Emily about meeting after work at the Empty Arms Hotel in order to "get to know each other a little better." Emily is amused and laughs at Dan's suggestive remarks, retorting that he is much too old for that nonsense, or that "even if I did agree, you'd probably die of embarrassment or a massive heart attack."
Dan always laughs at Emily's witty retorts. Dan and Emily never meet after work, but often tease each other and engage in this form of repartee in the work area.

Suppose that you are responsible for making arrangements for a business convention and that you have been charged with choosing a city for the convention that has the least expensive rooms. You have narrowed your choices to Atlanta and Houston. The table containing samples of prices for rooms in Atlanta and Houston is provided in the Excel Online file below. Construct a spreadsheet to answer the following questions. Because considerable historical data on the prices of rooms in both cities are available, the population standard deviations for the prices can be assumed to be $19.88 in Atlanta and $27.2 in Houston.
