1) (20 points) Many people believe that the daily change of price of a company's stock on the stock market is a random variable with mean 0 and variance $\sigma^2$. That is, if $Y_n$ represents the price of the stock on the $n$th day, then $$Y_n = Y_{n-1} + X_n \quad n \ge 1$$ where $X_1, X_2,...$ are independent and identically distributed random variables with mean 0 and variance $\sigma^2$. Suppose that the stock's price today is 100 and assume $\sigma^2 = 1$. (a) Plot 20 different trajectories of the stock prices over the next 10 days. You may use MATLAB's randn or Python's numpy.random.randn to generate normal random numbers. (b) Using Monte Carlo, estimate the probability that the stock's price will exceed 105 after 10 days. Report the results using 10, 100, and 500 samples. Hint: Let $X = Y_{10} = Y_0 + \sum_{i=1}^{10} X_i$. Use the fact that $P(X \ge 105) = E[I_{X \ge 105}]$, where $I_{X \ge 105}$ is an indicator random variable $$I_{X \ge 105} = \begin{cases} 1 & X \ge 105 \\ 0 & \text{otherwise} \end{cases}$$ (c) Compute this probability analytically. You can use the fact that if $X_i$'s are independent normal random variables with mean $\mu$ and variance $\sigma^2$, then $\sum_{i=1}^{n} X_i$ is also a normal random variable with mean $n\mu$ and variance $n\sigma^2$.

The VAT on goods in contact with the EU in 1991. However, the UK tried to change the rate for certain types of food and beverages. The new rate was set to apply to a group of people and/or to tie it to the price of a similar product. The VAT on books would be lowered from 25% to 22%. According to the Capital Statistical Bureau (CSB), they claimed that the entire VAT had been paid. However, I always doubted if the price would actually drop to the extent that the production in the market would be affected. Although, do you think this is the reason for the 15.1% drop? Let's take a better example of the Swedish book market to assess the impact of the VAT. The demand curve for books are -3n-1m, which means that the percentage change in the VAT will affect the quantity of books in millions. Assuming the VAT is a sales tax, the price elasticity of demand for books in this example is 0.25. So, if the price and quantity are the determinants of the demand for VAT, how many books were sold before the tax change?

Sheridan Corp. has been making and selling a variety of tabletops for many years. L'Adell, product manager for two versions of the company's tabletop products, Marbled and Solid, was comparing sales volumes for these two types of products. While she knew Sheridan's sales for the Solid tops had been declining, she was surprised to see the competitors' tabletop sales had been increasing. Was there something she didn't understand about her products' costs? Sheridan Corp. had always allocated MOH costs to its products using one cost driver: units produced. It made sense, as both products were of comparable size and went through the same process-though they did take different amounts of time in each area. She looked closely at the key activities and likely cost drivers and gathered the following information. Quantity of Cost Driver Activity Budgeted cost Cost Driver Marbled Solid Machining $156,600 Machine hours 2,400 3,400 Assembly 219,600 Direct labor hours 16,100 8,300 Quality control 88,200 Quality control hours 700 350 Total $464,400 Units produced 1,200 1,800 (a) Calculate the plant-wide MOH rate if Sheridan continues to use units produced as its only allocation base. Calculate the MOH costs per unit for each product: Marbled and Solid. (Round answer to 2 decimal places, e.g. 15.25.) Plant-wide MOH rate $ /unit produced

From 2000 to 2008, the percentage of adult deaths in the U.S. that required the filing of an Estate Tax Return: - Dropped from roughly 20% to 6% - Dropped to zero due to the Bush tax cuts of 2001 - Dropped from slightly over 2% to well below 1% - Dropped somewhat but remained higher in 2008 than during the Reagan years 2. The Openstax textbook states that efforts to reduce inequality: - Usually enhance overall economic output - Will tend to reduce economic output - Will enhance incentives to work - Are necessary when poverty rates exceed 30% 3. According to data presented in The Spirit Level, which of the following does NOT increase with more income inequality? - Rate of imprisonment - Social mobility - Drug use - Health and social problems
