Comment on whether each of the following statements is true or false.
(a) The Durbin Watson statistic is useless because it is based on assumptions that are rarely satisfied in time series regressions.
(b) a Durbin Watson statistic below 2 shows negative serial correlation because it is a statistic based on the AR(1) coefficient of the error term.
(c) Consider a time series process that follows a random walk drift. Is the first difference of that time series stationary? Is it weekly dependent?
(d) Coefficients of an autoregressive model can be estimated in an unbiased way by OLS, as long as all right hand side variables are strictly exogenous.
(e) a time series regression on non-stationary variables cannot produce unbiased estimates.

1 True/False
For each of the following statements say whether it is true or
false and explain why using a couple of sentences, graphs or
equations.
(a) If marginal cost of serving two markets is identical, then
an internationally discriminating monopolist would set the same
price in both markets.
(b) Granting a market economy status to China would make it more
difficult to impose antidumping duties on Chinese firms.

Comment with a brief
explanation whether the following statements are true or false:
1. The wavelength of
an electron moving with a velocity of 1.1*10^6 m/s is 6.6 nm.
2. In photoelectric
effect, whether an electron will be ejected by light is determined
not by the intensity of light but by the wavelength.
3. The temperature of
a star can be determined using its radiation spectrum.
4.
Resistance-temperature-detector is based on resistivity of a metal
decreasing with temperature.

True or false:
For each of the statements, determine whether it is true or
false, then explain in a few sentences why that is the answer.
Note: no marks will be given for answers that do not include an
explanation.
1. If money stops being a reliable store of value, then it
ceases to be useful as a medium of exchange.

Indicate whether each of the following statements is true or
false. If it is false, you must explain why it is false (you can
use equations as part of an explanation when needed). Not
explaining is the same thing as not answering. If it is true, no
explanation is needed:
a. The Romer model is useful because it allows us to
explain why poorer countries grow faster than richer
countries.
b. The main difference between the Solow model and the...

Determine whether each of the following statements is true or
false. If the statement is false, modify and rewrite it so that it
is a true statement.
a. When a molecule has two, degenerate, “infrared active”,
vibrational modes, the two vibrational modes will show absorptions
at different frequencies in the infrared spectrum.
b. For a given substance, strong intermolecular forces between
molecules of the substance can cause peak broadening of some of the
absorptions in the infrared spectrum of the...

True or False questions. Determine whether or not each of the
following statements is true. If a statement is true, prove it. If
the statement is false, provide a counterexample and explain how it
constitutes a counterexample. Diagrams can be useful in explaining
such things.
a) If the electric potential in a certain region of space is
constant, then the charge enclosed by any closed surface completely
contained within that region is zero.
b) A sphere of radius R is...

Indicate whether each of the following statements is true or
false. If false, indicate how to correct the statement.
a. The amount reported for accumulated other comprehensive
income (AOCI) on the balance sheet must be a positive amount
consistent with all other stockholders’ equity accounts.
b. Changes in AOCI are reflected in other comprehensive income,
which is different from net income.
c. Other comprehensive income does not imply a change in
cash.
