Most of the cost of a flat screen TV involves the LCD panel.Globally, 220 million flat screen TVs were sold in 2011 for $115 billion. Although scale economies in massive factories and volume discounts on electronic input components have driven the cost of LCDs down from $2,400 to $500 the last decade, the price has fallen even faster. In 2001, the average selling price of a large LCD panel was over$4,000. By 2011, this price had fallen below $600.Sony Corporation finds its flat screen TVs now fail to cover the full cost of the LCD panels and instead impose a $126 ($500 - $374) loss perTVsold.Nevertheless, the indirect fixed costs of the LCD factories including Korean Samsung, Japanese Sharp, Panasonic, and Sony constructed are partially covered by continuing its operation (continueproduction). Losses would be greater in the short run if they shut down. As an economic consultant, what would you advise Sony Corporation to do in light of the competition from the other manufacturers?(10marks )

1. The ability to make good decisions is the key to successful managerial performance. Discuss the common elements shared by all decision-making processes. Provide a real-world example to elaborate your answer.
2. Marginal analysis is one of the most useful concepts in economic decision making. Discuss and show examples including graphs to support your answer.

Differentiate between public good and private good, giving two features of each. With the aid of diagrams illustrate and then discuss why in the derivation of the aggregate demand for private goods, the goods are summed horizontally while the summation is vertical for public goods

Could John Rawls’ Principles of Justice have resulted in a better socio-political outcome , discuss your response in detail. 

The Recent May 2021 Arab (Palestinian)-Israeli conflict, arose from the alleged usurping of the Arab land East of the Old city of Jerusalem from the current Arab Owners to Israeli families who claim to have owned the land previously. These recurrent conflicts have their foundation in the 1948 establishment of the state of Israel. To create lasting peace, would Pareto theory of justice be sufficient for the distribution of land in Israel specially in Jerusalem. With the aid of an Edgeworth box, illustrate and then discuss the above statement in light of Nozick’s Principles of Justice.
