Question 1 Question 1 1 Point What does the “inverted firm” concept illustrate in platform businesses? A firm focused solely on internal production. A firm whose value creation is predominantly external. A traditional trading business model. A firm without network effects. Question 2 Question 2 1 Point What characterizes 'network effects' in a platform's growth? Decreased value with more users. Unchanged value regardless of user numbers. Increased cost with more users. Increased value with more users. Question 3 Question 3 1 Point Consider the ratio of market capitalization to employees for platform firms. Compared to product firms, this ratio appears to be about an order of magnitude higher. The best explanation for this is: The claim is false. The ratio of market capitalization to employees is barely any different between product and platform firms. Platforms operate as “inverted” firms where 3rd party outsiders produce much of the value rather than internal employees, so platforms do not own the resources they use. It’s a bubble. Irrational exuberance on the part of investors has overvalued these firms and there will be a market correction like that of the housing bubble. Demand economies of scale have produced giant vertically integrated firms that own a lot of assets. Supply economies of scale have produced giant vertically integrated firms that own a lot of assets. Question 4 Question 4 1 Point Which is the best definition of a platform as described in this course? An ecosystem of equal partners. A market for trading assets. An open architecture, with rules of behavior, designed to facilitate interactions. A foundation that others can build upon. A publicly agreed standard to which everyone adheres. Question 5 Question 5 1 Point Why are network effects crucial for platform firms? They decrease the platform’s operational costs. They reduce the platform’s value. They create a feedback loop that attracts more users to join. They increase the need for tangible assets. Question 6 Question 6 1 Point When more developers create apps for the Apple app store, the platform becomes more valuable for users. This exemplifies: A supply economy of scale. A demand economy of scale. A network effect. Both B and C. Question 7 Question 7 1 Point As you add friends on Facebook or Snapchat the value of your interactions increases. This is an example of: A supply economy of scale A demand economy of scale A network effect B & C A & C

2. Taylor series expansion for sin x is as follows: $ \sin x = x - \frac{x^3}{3!} + \frac{x^5}{5!} - \frac{x^7}{7!} + \frac{x^9}{9!} + \dots + (-1)^{n-1} \frac{x^{2n-1}}{(2n-1)!} $ Define a vector x which has 50 linearly spaced values between -? and ?. Define a variable y as sine values of x, calculated using Taylor series given above for 3 terms. Use for loop to accomplish the task. Use MATLAB's built-in sin (x) function to calculate sine values of same x vector and store them in variables called z. Create a set line plots comparing sine values for calculated using Taylor series and built-in function value. Label x-axis and y- axis properly and use legend to represent your plots. Run the same problem with 5 terms of Taylor series. [20 points] Hint: You will have two figures from this problem and each of the plots will have 2 line plots. Since x is a vector, Taylor series evaluation would require element wise operator (.^). In your report, showing code for only one run is sufficient.
