1. All of the economic thinkers that we have covered so far, including the mercantilists, the physiocrats, Adam Smith, Malthus, and Ricardo, have dealt with the topic of international trade as well as international trade policy. With the exception of Malthus, discuss the evolution of their ideas regarding those topics. You should mention their ideological leanings as well as the substance of their views. Do not forget to mention their policy recommendations.

1. Define the term skewness and kurtosis. With the aid of a diagram, describe the three types of kurtosis.            4marks
2. Describe the components of a time series and mention their applicability. 4marks

3. The table below relates to the sales of refrigerators by a certain firm in Kenya.

Year production in (000) Year Production in (000)

1996 17    2002 35

1997 20 2003   55

1998 19 2004 50

1999 26 2005 74

2000 24 2006 69

2001 40

Using this data;

1. Fit a straight line trend by the method of ordinary least squares
2. ii. Estimate the number of refrigerators that will be sold in the year 2009.

Modify the program below so the driver class (Employee10A) uses a polymorphic approach, meaning it should create an array of the superclass (Employee10A) to hold the subclass (HourlyEmployee10A, SalariedEmployee10A, & CommissionEmployee10A) objects, then load the array with the objects you create. Create one object of each subclass. The three subclasses inherited from the abstract superclass print the results using the overridden abstract method.

Below is the source code for the driver class:

public class EmployeeTest10A {

public static void main(String[] args) {
  
//creating scanner object to read input
Scanner sc = new Scanner(System.in);
  
//declaring and initializing variables
String firstName, lastName;
int answer, hrsWorked, otHrs, soldItems;
double otPay = 0;
double hrlyRate, regularPay, wklyPaycheck, bonus, itemCost;
  
//user input to begin or exit the program
System.out.println("Enter any number to continue or enter a -1 to exit "
+ "the program.");
answer = sc.nextInt();
  
//while loop
while(answer != -1) {
  
//Hourly Employee details
System.out.println("Please provide information for Hourly Employee.");
System.out.println("Enter the employee's first name:");
firstName = sc.next();
  
System.out.println("Enter the employee's last name:");
lastName = sc.next();
  
System.out.println("Enter the employee's hourly rate of pay:");
hrlyRate = sc.nextDouble();

System.out.println("Enter the number of hours worked by the employee:");
hrsWorked = sc.nextInt();

if (hrsWorked > 40) {
System.out.println("Enter the number of overtime hours worked "
+ "by the employee:");
otHrs = sc.nextInt();

otPay = ((hrlyRate * 1.5) * otHrs);
regularPay = hrlyRate * 40;
}
else {
otPay = 0;
regularPay = hrlyRate * hrsWorked;
}

//creating object
HourlyEmployee10A output = new HourlyEmployee10A(firstName, lastName,
hrsWorked, hrlyRate, regularPay, otPay);
//calling methods from "HourlyEmployee9C" to calculate weekly paycheck
output.WklyPaycheck();
wklyPaycheck = output.getWklyPaycheck();
//printing results
System.out.println(output);
  
//Salary Employee details
System.out.println("\nPlease provide information for Salaried Employee.");
System.out.println("Enter the employee's first name:");
firstName = sc.next();

System.out.println("Enter the employee's last name:");
lastName = sc.next();

System.out.println("Enter the employee's yearly salary:");
regularPay = sc.nextDouble();

System.out.println("Enter the employee's bonus percent:");
bonus = sc.nextDouble();

//creating object
SalariedEmployee10A salary = new SalariedEmployee10A(firstName, lastName,
regularPay, bonus);
//calling methods from "SalariedEmployee9C" to calculate weekly paycheck
salary.WeeklyPay();
//printing results
System.out.println(salary);

System.out.println("\nPlease provide information for Commission Employee.");
System.out.println("Enter the employee's first name:");
firstName = sc.next();

System.out.println("Enter the employee's last name:");
lastName = sc.next();

System.out.println("Enter the number of items sold by the employee:");
soldItems = sc.nextInt();

System.out.println("Enter the price of each item:");
itemCost = sc.nextDouble();

//creating object
CommissionEmployee10A commission = new CommissionEmployee10A(firstName,
lastName, soldItems, itemCost);
//calling methods from "CommissionEmployee9C" to calculate weekly paycheck
commission.WeeklyPay();
//printing results
System.out.println(commission);
  
//user input to continue or exit the program
System.out.println("\nEnter any number to continue or enter a -1 to "
+ "exit the program and calculate the total number of paychecks.");
answer = sc.nextInt();
}
//printing total number of paychecks calculated
System.out.println("\nTotal number of paychecks calculated: " + Employee10A.counter);
