Grexit or Not?

When the euro was introduced in 1999, Greece was conspicuously absent from the list of the EU member countries adopting the common currency. The country was not ready. In a few short years, however, European leaders, probably motivated by their political agenda, allowed Greece to join the euro club in 2001 although it was not entirely clear if the country satisfied the entry conditions. In any case, joining the euro club allowed the Greek government, households, and firms to gain easy access to plentiful funds at historically low interest rates, ushering in a period of robust credit growth. For a while, Greeks enjoyed what seemed to be the fruits of becoming a full-fledged member of Europe.

In December 2009, however, the new Greek government revealed that the gov- ernment budget deficit would be 12.7 percent for 2009, not 3.7 percent as previously announced by the outgoing government, far exceeding the EU’s convergence guideline of keeping the budget deficit below 3.0 percent of the GDP. As the true picture of the government finance became known, the prices of Greek government bonds began to fall sharply, prompting panic selling among international investors, threatening the sov- ereign defaults.

Several years into the crisis, the Greek government debt stands at around 180 percent of GDP and the jobless rate among youth is above 50 percent. The country’s GDP declined by about 25 percent. Severe austerity measures, such as sharply raised taxes and much reduced pension benefits, were imposed on Greece as conditions for the bail- outs arranged by the EU, IMF, and the European Central Bank. In addition, people were allowed to have only restricted access to their bank deposits, to prevent bank runs. Opin- ion polls indicate that the majority of people in Germany, the main creditor nation for Greece, prefer the Greek exit from the euro zone, popularly called Grexit, while some people in Greece are demanding Grexit themselves and restoration of the national cur- rency, the drachma.

Discussion points: (i) the root causes of the Greek predicaments, (ii) the costs and ben- efits of staying in the euro zone for Greece, (iii) the measures that need to be taken to keep Greece in the euro zone in the long run if that is desirable, (iv) If you were a disinter- ested outside advisor for the Greek government, would you advise Grexit or not? Why or why not?

In the Grossman model, is there a graph that best fits the thrifty phenotype hypothesis?

Assume we start with a total government debt of $0. What happens at the end of each year? Hint if I borrow $10 million then my debt is equal to $10 million.

The balance sheet shows your assets, liabilities, and equity of the business and is a key financial statement to analyze. If a business had cash of $200,000, accounts receivable of $500,000, a loan payable of $1,000,000, and equity of -$300,000, then what would this indicate about the business? What would be your overall thoughts on the health of this company and how could you improve its financial health? Would you want to invest in this company? Lead this company? Why or why not?

The net income of Thomas & Sons, a landscaping company, decreased sharply during 2018. The owner of the company, Jerry Thomas, anticipates the need for a bank loan in 2019. Late in 2018, Jerry instructs the company’s accountant to record $2,000 service revenue for landscape services for the McGrath family, even though the services will not be performed until January 2019. Jerry also tells the accountant not to make the following December 31, 2018 adjusting entries: Salaries owed to employees $900 Prepaid insurance that has expired $400

Requirements:

1) Calculate the total dollar amount of the affect on net income for the three suggested actions. Be detailed in your response so that we can follow how you calculated the total and why the amounts included in your total impact net income.

2) Of the four financial statements, which are impacted by the suggestions and where in the statement? Be specific and provide sufficient detail to suport your answer.

Part 1:

Write a program that has 2 classes. The first class is a test class with 2 methods; a main method, and a static method called drinkMilk(). The drinkMilk method returns void, and will throw an exception of type OutOfMilkException. The purpose of this exercise is to demonstrate that a method can get information back to the caller through an exceptions object that is thrown inside the called method and caught in the calling method.   (OutOfMilkException is the second class that you will create.)

The drinkMilk method will: save what time you start drinking your milk, here’s how:

            In the System class there is a method:

public static long currentTimeMillis()

Returns the current time in milliseconds.

Then, in an infinite loop, while (true) generate random integers between 0 – 1000 and perform an int division using the random integer as the denominator. Use anything except 0 as the numerator. You must use the Random class to generate random integers, not the Math class. Eventually you will execute a divide by zero.

Each time you generate a random number print out “Gulp.” Use print instead of println. When a division by zero exception is thrown, the drinkMilk method will catch the ArithmeticException exception. Within the catch block throw an exception of type OutOfMilkException.

(You are catching one kind of exception, creating a more descriptive exception that describes the situation, and throwing that exception.)

The outOfMilkException object will contain a value that indicates how long it took to drink the milk – in milliseconds, i.e., how long it took to generate a 0 value. The main method that catches the OutOfMilkException will printout the number of milliseconds that it took to drink the milk.

This demonstrates that information is "thrown" from the drinkMilk method to the main method. Keep in mind that the purpose of this exercise is to “throw” a piece of information from one method to another without using the usual mechanisms for passing information from one method to another, i.e., parameters and return values.

Note: It is not good practice to put any calculation inside an Exception object. These objects are holders of data only! No arithmetic operators, no method calling. Maybe a String concat + once in a while. The methods in the exceptions should never contribute to the solution; their role is exclusively to know about what went wrong, and to be thrown and caught.

Part 2: Assertions

Background:

The ‘assert’ keyword was added to Java in version 1.2. That caused a problem. “assert” was used for many years in C++, and when Java did not provide that mechanism, many Java programmers added a public method called ‘assert’ into their code.   When Java 1.2 came out, all of the code that used ‘assert’ wouldn’t compile, because they had a method name that matched a keyword.

assert somethingTrue;    // does nothing

assert somethingThatIsFalse;    // this will throw an AssertionError

        It became necessary to add some qualifiers to the compile and run commands in Java, so that assertions might be used at compile time and/or at run time. Since we are doing all of our work within Eclipse, you will need to figure out how to turn these on within the Eclipse environment.   Eclipse is generating the commands to compile and run the java programs – that’s good, we don’t have to type the commands, but it makes it harder when we need to change what command is generated.

The compile and run switches for Assertions are quite elaborate. Assertions are only used during development. Everyone will want to turn off this feature at run-time when the product is released.

When you have figured out how to turn Assertions on / off within Eclipse, post your solution on the discussion board. If the answer is already there, but you can add something, do it. You don’t need to re-post something that is already there.

Coding exercise:

Demonstrate using the assert keyword. Create a private method that takes an int parameter.

If the value passed in is negative, the method will assert something that is false, causing the method to throw an AssertionError.

Pass the value that was passed into the method to the constructor of the AssertionError class.

All of this is done with a single assert statement.

Why did I ask you to make this method private? It works the same with public methods. Put a comment in the code if you can find an answer that question. (It isn’t something you can figure out, you will need to read about the convention and the reason for having that convention.)

3. You are hard at work, setting up the apparatus to separate a 40:60 mixture of diethyl ether and toluene by simple distillation. Just as you are getting ready to begin the experiment, your lab partner mistakenly adds a small amount of sodium sulfate into the distillation flask. Would simple distillation still be appropriate or should you switch to fractional distillation? Explain.
