Question
Chapter 5, Problem 1RQ
To determine
To explain:Transaction’s category that appears in current account, current account balance, relationship between net exports and current account balance.
Expert Solution & Answer
Explanation of Solution
The balance of payment account records all the transactions in the different accounts for instance, the current account records the transections related to merchandise, service, income and unilateral transfers accounts. However, the current account balance refers to the sum of all these transactions.
The current account balance and net export are positively related. If the value of net export is lower, then the value of the current account balance will also be lower. However, the negative value of net export will lead to a deficit in the current account balance.

2. A firm’s production function is given by:Q = 10KLThe unit capital and labour costs are 2 and 1 pounds respectively. The firm is contracted to produce2000 units.(a) Write out the optimisation problem of the firm. (b) Express this problem using a Lagrangian function. (c) Find values of K and L which fulfil the contract with minimal cost to the firm. (d) Calculate the total cost to the firm.
3. Consider the following estimated regression equation, estimated using a sample of firms, where RDis total firm spending on research and development in USD ($), Revenue is total firm revenuein USD ($), and W ages is the firms’ total spending on wages in USD ($) (standard errors inparentheses):RDd = 1000(600)+ 0.5(0.1)Revenue + 1.5(0.5)W ages,(a) Interpret the coefficients on each of the explanatory variables. (b) Which of the three coefficients are statistically significant at the 5% level of significance? Howdo you know? A researcher runs a two-sided statistical test of the null hypothesis that both the coefficients onthe explanatory variables above are jointly equal to 0.25 (mathematically, that β1 = β2 = 0.25),and reports a p-value of 0.045.(c) What does this p-value mean for the outcome of the test? (d) What would an appropriate two-sided alternative hypothesis look like?
