Q

When is it appropriate to use the t-distribution

A

It has n-1 df - It is appropriate when σ is not known and the population is small. When paired, it should come from two independent samples from normally distributed populations.

Q

When do we use a paired comparisons test

A

It is used with the mean of the differences between the paired observation of two dependent, normally distributed samples. The t-stat is d/sd where sd = sd/sqrt(n) where d is the average difference of the n paired observations.

36
Q

What is the difference between parametric and nonparametic tests

A

Parametric tests - make assumptions regarding the distribution of the population from which samples are drawn. Nonparametic test make few assumptions about the sample population.

A

Use the t-statistic with n-2 df calculated (r(sqrt(n-2))/sqrt(1-r^2))

Q

How to test if we are using a contingency table

A

Use chi squared test with (r-1)(c-1) df. The test is ∑r∑c (Oi,j - Ei,j)^2/Ei,j

40
Q

What is R2 for a regression

A

it is 1 - [SSR (Sum of Squares) / SST (Sum of Square Total)] = SST-SSE/SST

41
Q

When looking at lin and log models which is the relative change

A

Logs are always the relative change

42
Q

43
Q

What is the elasticity of products

A

% change in quantity demanded/% change in own price can sub denominator % change in price of related goods or % change in income

44
Q

How to figure out if demand is elastic

A

if price elasticity is greater than 1 is elastic. Elasticity is % in quantity/% change in price

45
Q

How to figure out if substitute or complement

A

If cross-price elasticity is greater than 0 it is a substitute and if it is less then it is a complement

46
Q

How to figure out if it is an inferior good

A

If the income elasticity is less than 0 inferior good and greater than 0 then normal good

47
Q

Difference between income and substitution effect

A

The income effect is the change in the consumption of goods by consumers based on income and purchasing power.
The substitution effect occurs when consumers replace cheaper goods with more expensive items due to price changes or an improved financial condition, and vice versa.

48
Q

What is a giffen good

A

A giffen good is an inferior good where a decrease in the price has a new result of decreasing the quantity consumed

49
Q

What is a veblen good

A

A good where an increase in price results in an increase in quantity consumed and not suooirted by the axioms of the theory of demand

50
Q

What is considered short run and long run marginal costs curves

A

Only for firms in perfect competition where the short-run marginal cost curve is above the AVC while long-run is above the TC curve. For all other firms they do not have well-defined supply functions.

51
Q

What do competitive firms use to determine pricing strategy?

A

competition is where marginal revenue equals marginal cost

52
Q

What is a concentration and HH Index for firms?

A

Concentration ration is the percentage of the market held by N firms and HH index measures as the sum of the squared market shares of the largest N firms which better reflects the effect of mergers

53
Q

What is the formula for GDP?

A

C+I+G+(X-M) - Consumption, Investment, Government, Exports - Imports)

54
Q

What is the balance of trade formula?

What is the formula for the real exchange rate

A

Nominal exchange rate x (CPI base currency/CPI Price Currency)

79
Q

How to calculate appreciation and depreciation

A

Can only calculate based on base currency and then need to be flipped to calculate the price currency which is the new base

80
Q

What is the difference between points and exchange given as percentage

A

Points you will add +1 point add .0001 to the state rate and then when doing percentage then just do the percentage gain

81
Q

What is formal dollarization

A

It is when a country uses the currency of another country

A

It is the monetary authority that attempts to influence the exchange rate in response to specific indicators
