Isaac's Errata for 2nd edition of Jones's Macroeconomics
========================================================

p. 23, "government purchases ... crowded out private investment and consumption."
   Investment did decline, but that is a natural response to war.
   Saying investment was "crowded out" is a presumptuous interpretation.
   Furthermore, consumption did not decline in real value.
   (The graph only shows a fall as a percentage of GDP.)
p. 63, problem 10
   In these problems y, k, l, and m are
   just arbitrary variable names; the
   resemblance to the notation used in
   the text is not helpful.
p. 65, Figure 3.10
   The origin of the ratio scale is 0 (instead of 1)
p. 143, Table 6.1
   A_t is listed as one of the four "unknowns",
   which is a little confusing.  TFP is a predetermined
   endogenous variable, so as the model is laid out in
   this table, it would be better to say that
   Delta A_{t+1} is the fourth "unknown".
   Or, since A_0 is listed as one of the "parameters" of
   the model, it would be even clearer to explicitly write
   Delta A_{t+1} = A_{t+1} - A_t
   and say that A_{t+1} is the fourth "unknown".

p. 22, "government purchases ... crowded out private investment and consumption."
   Investment did decline, but that is a natural response to war.
   Consumption did not decline.
p. 62, problem 9
   The intent is for you to approximate,
   following the examples in Table 3.1.
p. 62, problem 10
   In these problems y, k, l, and m are
   just arbitrary variable names; the
   resemblance to the notation used in
   the text is not helpful.
p. 64, Figure 3.10
   The origin of the ratio scale is 0 (instead of 1)
p. 73, Table 4.2, output equation
   Total factor productivity is missing from production function.
p. 112--114, Figures 5.4, 5.5, 5.6, 5.7
   Change of notation.
   An asterisk now indicates a steady-state value.
