...WEEK ONE Homework. Answer all questions, a through f. On questions c, d, e and f show your math. If you do not show your math you do not receive points. The general demand function for a good, Good A, is… QD = 800 – 5*P + 0.02*M + 6*PR + 3*T + 5*PE + .4*N Where QD = quantity demanded of Good A per month P = the price of Good A M = average household income PR = the price of a related good, we’ll call it Good B T = a consumer taste index PE = the price consumers expect to pay next month for Good A N = the number of buyers in the market a. Is Good A a normal good or an inferior good? How do we know exactly? Good A is a normal good, and we know this because the sign on the coefficient in front of the income variable M is positive. (If the equation read QD = 800 – 5*P - 0.02*M … then it would be an inferior good.) The positive sign means that as income (M) increases, so too does the quantity demanded of this good. b. Are Good A and Good B complements or substitutes? How do we know exactly? Goods A and B are substitutes, and we know this because the sign on the coefficient in front of the “Price of Related Good” variable, PR, is positive. (If the equation read QD = 800 – 5*P + 0.02*M - 6*PR… then they would be complements.) The positive sign means that as the price of the OTHER good, Good B, increases the quantity demanded of this good, Good A, increases. This is because as the price of the other good, Good B, increases people are shifting...

But often the meaning of research methodology, especially methodology, is misunderstood. It is most often associated with creating a questionnaire, collecting a set of data and afterwards applying some rudimentary statistics.3 Obliviously this is naïve and incorrect.

...ECMT 1010 ASSIGNMENT 2012 QUESTION 1 Fig 1.1 Histogram illustrating the number of years of education undertaken by farmers in Fiji. Figure 1.1 shows a histogram of the number of years of education Fijian farmers have undergone. From the histogram we see that the years of education range from 0 to 18 years with the data approximately normally distributed. Most frequently education years is above 7 with the most frequent number of years being between 7 and 11 years. The least frequent years of education is above 16 years with only 4 out of the 308 sampled farmers having more than 16 years of education. QUESTION 2 Fig 2.1 Scatter plot of department store and food retail turnover. Figure 2.1 is a scatter plot of the turnovers for food retailing and department stores from 1982-2008. There is a clear upward trend indicating that as food retail turnover has risen department store turnover has also risen. The data follows a fairly distinct trend line with few outliers indicating a strong positive correlation between the two variables.
