Chapter 16, Problem 16.1.1RQ
What is the law of one
Expert Solution & Answer
To determine
Law of one price and arbitrage.
Explanation of Solution
According to the law of one price, identical products need to be sold for the same price everywhere. Arbitrage is a practice, whereby, a product is bought from one market at a low price and is resold in another market at a higher price.
Economics Concept Introduction
Concept introduction:
Law of one price: The law states that identical products need to be sold for the same price everywhere.
Arbitrage: Arbitrage is the practice of buying a product at a low price from one market and reselling it at a higher price in another market.

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?
