Consider a hypothetical situation with the following information. Spot rate of Canadian dollar: $0.78 180-day forward rate of Canadian dollar: $0.85 180-day Canadian interest rate: 4% 180-day U. S. interest rate: 4.5% (1) Describe four actions for a U. S. investor (or a Canadian investor) to take in order to carry out a covered interest arbitrage. (2) Given the information above, compute the 180-day net yield to the investor who carries out a covered interest arbitrage.

ans.

heterothermic organisms include those organisms that can switch between homeothermic (having body temperature higher than environment) and poikilothermic (having variation in internal body temperature) strategies.

some migratory birds show heterothermy as they decrease their metabolic rate during cold nights to keep their body temperature low. drop in metabolic rate allows increase in production efficiency of birds that reduces the internal body temperature to make it equal to external cold temperature during cold nights.

thus, the correct answer is 'birds allow their temperature drop in order to increase their production efficiency.'

the correct answer is economics is a game without winners or losers.

unlike sports or games economic is a game without losers or winner rather it is a game where everyone wins. parties of business doing businesses exchange money with each other and hence exchange is done on the basis of goods. one party takes the goods and other sales it so there is winner on both sides. each party values more highly the good it gets than the good it gives up. both sides exchange only because both intend to increase their value. so there is no concept of lose or win.
