Alternative Production Procedures and Operating Leverage
Assume Sharpie, a brand of Sanford LP, is planning to introduce a new executive pen that can be manufactured using either a capital-intensive method or a labor-intensive method. The predicted manufacturing costs for each method are as follows:

  Capital Intensive Labor Intensive
Direct materials per unit $ 5.00 $ 6.00
Direct labor per unit $ 5.00 $ 10.00
Variable manufacturing overhead per unit $ 4.00 $ 2.00
Fixed manufacturing overhead per year $ 2,440,000 $ 700,000


Sharpie's market research department has recommended an introductory unit sales price of $40. The incremental selling costs are predicted to be $500,000 per year, plus $2 per unit sold.

(a) Determine the annual break-even point in units if Sharpie uses the:
1. Capital-intensive manufacturing method.
Answer units

2. Labor-intensive manufacturing method.
Answer units

(b) Determine the annual unit volume at which Sharpie is indifferent between the two manufacturing methods.
Answer units

(c) Management wants to know more about the effect of each alternative on operating leverage.
1. Explain operating leverage and the relationship between operating leverage and the volatility of earnings.

They have little or no correlation because they are unrelated.

They are positively correlated, with increases in operating leverage accompanied by increases in the volatility of earnings.

They are negatively correlated, with increases in operating leverage accompanied by decreases in the volatility of earnings.



2. Compute operating leverage for each alternative at a volume of 250,000 units. Round your answers two decimal places.


Capital-Intensive operating leverage Answer
Labor-Intensive operating leverage Answer

3. Which alternative has the higher operating leverage? Why?

The labor intensive method has a higher operating leverage because of higher variable conversion costs.

The labor intensive method has a higher operating leverage because of lower variable manufacturing overhead.

The capital intensive method has a higher operating leverage because of the greater use of fixed assets.

The capital intensive method has a higher operating leverage because of the higher variable manufacturing overhead.

CVP Analysis and Special Decisions
Smoothie Citrus Company buys a variety of citrus fruit from growers and then processes the fruit into a product line of fresh fruit, juices, and fruit flavorings. The most recent year's sales revenue was $4,400,000. Variable costs were 60 percent of sales and fixed costs totaled $1,400,000. Smoothie is evaluating two alternatives designed to enhance profitability.

One staff member has proposed that Smoothie purchase more automated processing equipment. This strategy would increase fixed costs by $300,000 but decrease variable costs to 54 percent of sales.

Another staff member has suggested that Smoothie rely more on outsourcing for fruit processing. This would reduce fixed costs by $300,000 but increase variable costs to 65 percent of sales.

Round your answers to the nearest whole number.

To a greater or lesser degree, many governments can be considered pregmatic nationalists when it comes to foreign direct investment (FDI); this means it has both benefits and costs. FDI can benefit a host country by bringing capital, technology, and jobs, and it can also have a negative effect on a country's balance of payments. Accordingly, government policies are shaped by a consideration of these costs and benefits of FDI. 

 Home countries can adopt policies designed to both encourage and restrict FDI. Host countries try to attract FDI by offering incentives and try to restrict FDI by dictating ownership restraints and requiring that foreign multinational enterprises (MNE) meet specific performance requirements.

You're helping some security analysts monitor a collection of networked computers,

You're helping some security analysts monitor a collection of networked computers, tracking the spread of an online virus. There are n computers in the system. labeled \(01, C 2, \ldots, \mathrm{Cn}\), and as input you're given a collection of trace data indicating the times at which pairs of computers communicated. Thus the data is a sequence of ordered triples \((\mathrm{Cl}, C j, t k)\), such a triple indicates that \(C /\) and \(C j\) exchanged bits at time \(t k\). There are \(m\) triples total

We'll assume that the triples are presented to you in sorted order of time For purposes of simplicity, we'll assume that each pair of computers communicates at most once during the interval you're observing.

The security analysts you're working with would like to be able to answer questions of the following form: If the virus was inserted into computer Ca at time \(x\), could it possibly have infected computer \(\mathrm{Cb}\) by time \(y\) ? The mechanics of infection are simple: if an infected computer Ci communicates with an uninfected computer \(\mathrm{Cj}\) at time tk (in other words, if one of the triples \((\mathrm{Ci}, \mathrm{Cj}, t k)\) or \((\mathrm{C} j, \mathrm{Cl}, t k)\) appears in the trace data), then computer \(C j\) becomes infected as well, starting at time tk. Infection can thus spread from one machine to another across a sequence of communications, provided that no step in this sequence involves a move backward in time. Thus, for example, if \(C i\) is infected by time \(t k\), and the trace data contains triples \((C i, C j\) \(t k)\) and \((C j, C q, t r)\), where \(t k \leq t r\), then Cq will become infected via \(C\). (Note that it is okay for \(t k\) to be equal to tr ; this would mean that Cj had open connections to both \(C\) i and \(C q\) at the same time, and so a virus could move from \(\mathrm{C}\) i to \(\mathrm{Cq}\).)

For example, suppose \(n=4\), the trace data consists of the triples

\((\mathrm{C} 1, \mathrm{C} 2,4),(\mathrm{C} 2, \mathrm{C} 4,8),(\mathrm{C} 3, \mathrm{C} 4,8),(\mathrm{C} 1, \mathrm{C} 4,12)\)

and the virus was inserted into computer \(\mathrm{C} 1\) at time 2 . Then \(\mathrm{C} 3\) would be infected at time 8 by a sequence of three steps: first \(C 2\) becomes infected at time 4 , then \(C 4\) gets the virus from \(C 2\) at time 8 , and then \(\mathrm{C} 3\) gets the virus from \(\mathrm{C} 4\) at time 8 . On the other hand, if the trace data were

\((C 2, C 3,8),(C 1, C 4,12),(C 1, C 2,14)\)

and again the virus was inserted into computer \(\mathrm{C} 1\) at time 2 , then \(\mathrm{C} 3\) would not become infected during the period of observation although \(C 2\) becomes infected at time 14 , we see that C3 only communicates with \(C 2\) before \(C 2\) was infected There is no sequence of communications moving forward in time by which the virus could get from \(\mathrm{C}1\) to \(\mathrm{C} 3\) in this second example.

Design an algorithm that answers questions of this type given a collection of trace data, the aigorithm should decide whether a virus introduced at computer Ca at time x could have aeter comouter Cb by time \(y\). The algorithm should run in time \(O(m+n)\)

A firm uses the pure chase strategy of aggregate planning. It produced 1000 units in the last period. Demand in the next period is estimated at 800, and demand over the next six periods (its aggregate planning horizon) is estimated to average 900 units. Which of the following tactics would be most representative of following a chase strategy?
  • add 100 units to inventory in the next period
  • add 200 units to inventory in the next period 
  • hire workers to match the 100-unit difference
  • lay off workers to match the 200-unit difference
