For each of the 3 causal questions (i, ii, and iii) answer the following (and label your answers clearly):

This week's graded discussion forum requires students to demonstrate their understanding of market interest rates and the impact of interest rates on marketable securities. Marketable securities include low-interest return investments such as money market deposits and certificate of deposits, debt securities (bonds) with fixed coupon rate but fluctuating yields, and equity investments. To prepare for this assignment, students are to study the chapter readings and conduct additional research to prepare a short analysis posting of 400 words (min). See the description in Week 1 Readings for selection criteria for your article. The primary focus of the selected article must be specific to U.S. interest rates within the last 12 months.

In your analysis piece, synthesize the primary point(s) of your selected article with a minimum of two concepts presented in the required chapter readings (1, 2, and 3). In your analysis piece you are to describe and address each of the following:

1. Why is your article relevant? Articulate the reasons for relevancy.
2. What are the relationship(s) between the chapter concept(s) and your article and analyze the relationship(s)?
3. What is the impact of the relationship to the investment policy of the firm, and/or individual investor?

Explain the Keynesian framework for aspect of aggregate output and aggregate demand

The production function of a firm is given by Q(K,L) =15K^(1/4) L^(1/4) . Wage is

$3 per unit of labor (L), and rent is $6 per unit of capital (K).
(1) The firm’s objective is to produce Q units of output at minimum cost. Write the Lagrangian and derive the FONC.
(2) Find the optimal levels of K, L, and λ given Q.

(3) Find the minimum cost given Q = 100. Find the firm’s minimum cost functiongiven any Q.

(4) Explain the meaning of the optimal λ obtained in part (2).

(5) Check the SOSC.

Could someone help me with this question step by step? Thanks!!

You are an employee of an U.S. firm that produces personal computers in Thailand and then exports them to the U.S. and other countries for sale. The personal computers were originally produced in Thailand to take advantage of relatively low labor costs and a skilled workforce. Other possible locations considered at that time were Malaysia and Hong Kong. The US government decides to impose punitive 100% ad valorem tariffs on imports of computers from Thailand to punish the country for administrative trade barriers that restrict U.S. exports to Thailand. How do you think your firm should respond? What does this tell you about the use of targeted trade barriers?
