Consider a fictional company ABC plc, which paid the following dividends per share in the past as shown in table 4.

Table below presents information collected by the Economist in January 2021. More specifically it shows data on Big Mac prices in different countries an on the actual exchange rate.
Table 5 Big Mac prices in different countries
Country | Big Mac price (local currency) | Big Mac price in the USA (US$) | Implied purchasing Power Parity (LC/US$) | Actual Exchange rate | Local Currency under (-) or over (+) valuation (in %) |
Bahrain | 1.50 dinars | $5.66 | | 0.38 | |
Chile | 2,940 pesos | $5.66 | | 719.42 | |
Denmark | DKr30.00 | $5.66 | | 6.12 | |
Sweden | SKr52.88 | $5.66 | | 8.30 | |
Thailand | 128 baht | $5.66 | | 30.13 | |
i.) Based on the absolute version of the purchasing power parity calculate the implied exchange rate and fill out the 4th column in the table. Calculate the local currency over/under-valuation and record your results in the last column.

Consider two different portfolios:
· Portfolio A contains XYZ stock trading currently at £50
· Portfolio B contains XYZ stock and a European put option written on one XYZ stock. The put option currently costs £3, has a strike price of £50 and an expiration date in 3 months.
Calculate the returns on Portfolio A & Portfolio B in three months’ time if:
· XYZ price decreases to £30
· XYZ price increases to £70
Examine these returns and reflect on the role that the put option plays in Portfolio B.

Two airlines, A and B, serve a given route. Each firm can choose to charge a low ($100) or a high ($200) ticket price. If both firms set the price to be high ($200), each firm earns $80,000 in net profits per week by operating the route. If, alternatively, both firms chose to price low ($100), each firm earns $20,000 in net profits per week. If one firm charges the low price while the other charges the high price, then the firm that prices low sells more tickets and earns a higher profit of $100,000, while the firm that prices high sells fewer tickets and earns a profit of $10,000.
i.) Assume that each firm makes its pricing decision without knowing what the other firm has decided to do. Draw the payoff matrix.
(4 marks)
ii.) Both firms have a dominant strategy. What is it?
(4 marks)
iii.) Find the Nash equilibria and the equilibrium payoffs in this game.

Two firms, X and Y, are considering opening new production lines in order to enter into a new market. The matrix of payoffs and strategies for the two firms is given in Table 6. The first number in each cell represents X’s net profits in million $, while the second number represents Y’s net profits in million $. Assume that each firm makes its decision without knowing what the other firm has decided to do.
Table 6 Matrix of payoffs and strategies
Y |
| | Enter | Out |
X | Enter | -10, 10 | 100, 0 |
| 0, 100 | 0, 0 |
i.) Find the Nash equilibrium payoffs in this game
(4 marks)
ii.) Assume that if X decides to enter the new market, it can cross-subsidise its new production line by $20 million from other sources (in which case X’s payoffs for entering the new market increase by $20 million). Draw the new payoff matrix that takes into account the effect of the subsidy on X’s payoffs. Find the Nash equilibria and the equilibrium payoffs in this game. Explain your answer.
(5 marks)
iii.) Comment on your results by comparing your answers to sections i) and ii). Do you think that X should subsidise the new production line? Explain your answer.

(2 marks)
ii.) Convert this information on the number of calls to a probability distribution. What is the mean number of emergency calls per day?

An economist would like to study the link between institutional and economic development across countries. For this purpose, the economist downloaded the World Bank’s Rule of Law indicator that captures “the quality of contract enforcement, property rights, the police, and the courts, as well as the likelihood of crime and violence”. The Rule of Law is a composite country-level measure that ranges from -2.5 (very weak or no rule of law) to 2.5 (very strong rule of law). The economist then estimates a regression with GDP per capita (measured in constant international dollars based on purchasing power parity rates) as the dependent variable, and Rule of Law as the independent variable. The results are summarized in the Tables 8 and 9.
i.) Write out the regression equation
(2 marks)
ii.) Estimate the expected GDP per capita in a country where the Rule of Law measure equals XXXXXXXXXXCompare this value with the expected GDP per capita in a country where the Rule of Law measure equals 1.2.

iii.) Determine the proportion of the total variation in the dependent variable that is explained, or accounted for, by the variation in the independent variables.
(2 marks)
iv.) Interpret each of the slope coefficients
(4 marks)
v.) Comment on the reported 95% confidence intervals
