ECONOMICS Public sector workers in many nations have the right to form unions, engage in collective bargaining, and go on strike. The story, however, is much different in the United States. State and federal laws often place restrictions on the ability of public employees to form unions, negotiate contracts, and walk off the job. Government officials cite the need to protect the public interest. In turn, supporters of public workers cite the need to receive fair wages and benefits, and establish safe working conditions, just like workers in the private sector. In 1990 the Louisiana Supreme Court ruled that "public sector employees are covered by the state's 'Little Norris LaGuardia Act' which protects all employees in the exercise of their right to engage in concerted activities.' The court rejected the... argument that public employee strikes are illegal under common law (since Louisiana is not a common law state) and found that the state constitution gives public employees the same right to engage in collective bargaining as held by their counterparts in the private sector. Except for police strikes which by their nature endanger the public, public employee strikes are legal as long as they don't pose danger to public health and safety.'" According to Document A, why did the Louisiana Supreme Court support public workers' right to strike? A. Public workers, like police officers, are not essential to public safety. B. Public workers are covered under the state's "Little Norris LaGuardia Act." C. Public workers cannot engage in collective bargaining. D. The state's common laws allow it. ECONOMICS An investment company sells three types of pooled funds, Standard (S), Deluxe (D), and Gold Star (G). Each unit of S contains 12 shares of stock A, 16 of stock B, and 8 of stock C. Each unit of D contains 20 shares of stock A, 12 of stock B, and 28 of stock C. Each unit of G contains 32 shares of stock A, 28 of stock B, and 36 of stock C. Suppose an investor wishes to purchase exactly 220 shares of stock A, 176 shares of stock B, and 264 shares of stock C by buying units of the three funds. (a) Set up equations in s, for units of S, d, for units of D, and g, for units of G whose solution would provide the number of units of S, D, and G that will meet the investor's requirements exactly. (b) Solve the system set up in (a) and show that it has infinitely many solutions, if we naively assume that s, d, and g can take on arbitrary real values. (c) Pooled funds can be bought only in units that are non-negative integers. In the solution to (b) above, it follows that we must require each of s, d, and g to be non-negative integers. Enumerate the solutions in (b) that remain after we impose this new constraint. (d) Suppose the investor pays $300 for each unit of S,$400 for each unit of D, and $600 for each unit of G. Which of the possible solutions from part (c) will minimize the total cost to the investor?
