Consider a market with a demand curve given (in inverse form) by 𝑃(𝑄)=80−0.50𝑄P(Q)=80−0.50Q, where 𝑄Q is total market output and 𝑃P is the price of the good. Two firms compete in this market by simultaneously choosing prices 𝑝1p1 and 𝑝2p2, where the lower-priced firm captures the entire market (and a tie splits the market 50/50). This is an example of Choose one:A. Bertrand competition.B. Cournot competition.C. perfect competition.D. Stackelberg competition.

Let $\hat{\beta}_0$ and $\hat{\beta}_1$ be the OLS intercept and slope estimators, respectively, and let $\bar{u}$ be the sample average of the errors (not the residuals!). (i) Show that $\hat{\beta}_1$ can be written as $\hat{\beta}_1 = \beta_1 + \sum_{i=1}^{n} w_i u_i$ where $w_i = d_i/SST_x$ and $d_i = x_i - \bar{x}$. (ii) Use part (i), along with $\sum_{i=1}^{n} w_i = 0$, to show that $\hat{\beta}_1$ and $\bar{u}$ are uncorrelated. [Hint: You are being asked to show that $E[(\hat{\beta}_1 - \beta_1) \cdot \bar{u}] = 0.$

Question #4: is_identical (num_1, num_2) 10 pts Given two positive numbers, num_1 and num_2, the function returns True if after removing all sequences of repeated digits from both integers and replacing it with only one instance, num_1 is equal to nu_2, False otherwise. • You are NOT allowed to type convert num to a string <str(num)>, add the digits into a list to traverse or process the number, or to use of the math module Preconditions and Postconditions num_1: int -> positive integer num_2: int -> positive integer Returns: bool -> True is num_1==num_2 after removing sequences of repeated digits, False otherwise Example: >>> is_identical (51111315, 51315) #1111 is replaced with 1, 51315 == 51315 True >>> is_identical (7006600, 7706000) # 7060==7060 True >>> is_identical (135, 765) False >>> is_identical (2023, 20) False
