A

Summary Introduction

To explain: Calculate the total cash flow in strategy at different time intervals and as per the given information.

Introduction: An arbitrage strategy is given, first future contract price F(T1) at a time period of T1 , now consider the next time period T2 with future price F(T2) .

Answer to Problem 19PS

Thus the final cash after T2 years will be F(T2)F(T1)×(1+rf)(T2T1) .

Explanation of Solution

Given information: Future contract price F(T1) at a time interval of T1 , next future price is F(T2) with time period T2 .

There are two future prices with definite time period, initially the cash was zero, after one year it will be P1F(T1) and after two year it will be zero again. Short selling of future contract after two year will be F(T2)P2 . Number of assets at T1 will be - P1 and sell asset will be + P2 . Now to borrow future price at T1 will be F(T1) and at T2 will be F(T1)×(1+rf)T2T1 . Now the final cash flow after T2 years will be F(T2)F(T1)×(1+rf)(T2T1) .

B

Summary Introduction

To explain: If arbitrage opportunity is none then why profit will be zero at time T2 .

Answer to Problem 19PS

Thus investment at this period is zero and also it is risk free. Hence the total profit also is null when there is no arbitrage opportunity.

Explanation of Solution

Given information: Future contract price F(T1) at a time interval of T1 , next future price is F(T2) with time period T2 .

In the absence of the arbitrage opportunity the profit will be zero because investment in time T2 is risk free and net investment is also zero in this time period. Hence the profit will also be zero at this condition.

C

Summary Introduction

To explain: Establish the relation between F(T1) and F(T2) for the profit at T2 to be equal to zero.

Answer to Problem 19PS

Hence relation between F(T1) and F(T2) is given by this equation F(T2)=F(T1)×(1+rf)(T2T1) .

Explanation of Solution

Given information: Future contract price F(T1) at a time interval of T1 , next future price is F(T2) with time period T2 .

At last stage for profit should be zero at time T2 , the below relation should be followed by T1 and T2

  F(T2)=F(T1)×(1+rf)(T2T1)

Article: Current Bank Problem Statement The general problem to be surveyed is that leaders lack an understanding of how to address job demands, resulting in an increase in voluntary termination, counterproductive workplace outcomes, and a loss of customers. Bank leaders discovered from customer surveys that customers are closing accounts because their rates are not competitive with area credit unions. Job demands such as a heavy workload interfered with employee performance, leading to decreased job performance. Healthcare employees who felt the organization’s benefits were not competitive were more likely to quit without notice, resulting in retention issues for the organization. Information technology leaders who provide job resources to offset job demand have seen an increase in (a) new accounts, (b) employee productivity, (c) positive workplace culture, and (d) employee retention. The specific problem to be addressed is that IT technology leaders in the information technology…
