Appendices

Tables I and II: Column (1) comes from USDC [1975: 126], series D-4. Subtracting those employed in agriculture (series D-6, p. 127) gives column (2). Multiplying by M. Reich's [1986: 125, table 4-C] nonfarm proletarianization rate (interpolated between 1900, 1910, 1920, and 1930) gives column (3). An index of weekly hours in manufacturing was used as a proxy for hours of work in the non-farm sector: it was an average of three similarly-moving series (D-831, D-803, and D-765) with overlapping time periods. (Other indices of working hours showed similar trends: see series D-796 (p. 169) and D-846,847 (p. 172).) This was multiplied by column (3) to get column (4). Finally, to get column (5), column (4) was multiplied by nonfarm output per labor-hour (series D-684). All are converted to index numbers.

Column (6) is the growth rate of column (1), while the sources of all the data is explained above. Column (7) is growth of column (5) due to the subtraction of the farm sector. Column (8) is that due to changes in the proletarization rate. Column (9) is that due to changes in hours per week, while column (11) is due to changes in productivity. Column (13) is from USDC [1975: 232], series F-128. Except for 1929, average data was used.

Table III: Column (14) is from USDC [1975: 126], series D-10, adjusted so that it measures unemployment as a percentage of the nonfarm labor force rather than employment. Column (15) is Romer's [1986] total-economy unemployment rate, multiplied by the ratio of the Lebergott nonfarm unemployment rate to the Lebergott total-economy unemployment rate. Column (16) is from Douglas [1930: 445]. Extrapolations for 1928 and 1929 are based on a simple regression equation for 1900-27:

D = a + bAS + uT + E,

where D is the Douglas series, AS is the alternative series (Lebergott non-farm or estimated Romer), T is a time trend, and E is random error.

Non-farm: Mage [1963: 174, 256-7]: total pre-tax gross surplus value minus capital consumption divided by capital stock.

Merged Corporate: a merged series, calculated from Epstein and Gordon [1939], Goldsmith [1955: 925], and merged NBER data [USDC, 1975: 941, series V304, V292].

Unadjusted Manufacturing: (1 - share of total payroll in manufacturing value-added) [USDC, 1975: 666, series P10 and P7] divided by the ratio of total capital to value-added in manufacturing, in 1929 dollars [Creamer, Dobrovolsky, and Borenstein, 1960: 40, column 4]. Data years are marked by the "X" and the curve was linearly interpolated between those dates. The share of payroll for 1900 was extrapolated between 1899 and 1900.

Diagram 3-C: Unadjusted manufacturing: see diagram 3-B. Adjusted manuf.: this is the unadjusted rate, times (RM - EM)*YM/(YM - EM)*RM, where data come from Martin [1939]. See diagram 1 for definitions. This equals the actual non-entrepreneurial profit rate if the output-capital ratio for non-entrepreneurial manufacturing equals that of the manufacturing sector as a whole.

Diagram 3-D: Adjusted profit rate: see diagram 3-C. Merged corporate, see diagram 3-B. Taitel is from Taitel [1941], profit rate on net worth of the corporate system, before taxes, using 1923 valuation of net worth.

The Federal Reserve's index of manufacturing output was merged with Frickey's index, using the NBER's values for 1914 and 1919. Capacity utilization is measured [[p. 179]] as a ratio between the actual production index and the exponential trend (between 1860 and 1970). Data points based on the FRB are marked with an "X," while those based on Frickey are marked with an "O." The section of the line based on interpolation has no marking.

In the leading sector, net income (Y) is distributed between surplus (R) and wages (W), according to a distributive factor ** s** and the rate of capacity utilization (u). The former variable reflects class conflict, which in turn primarily depends on the progress of accumulation and the degree and type of organization of the classes. The latter variable reflects the fact that as capacity use rises, overhead labor is used more fully so that a greater surplus is realized relative to output.

R/Y = ; 1 > b > 0 ; s > 0W/Y = 1 - bs^ub |

where ** b** is a coefficient of elasticity of the surplus share with respect to capacity utilization. On the other hand,

For simplicity, assume that the economy operates at or below full utilization (*u*__<__ 1) so that there is no squeeze on surplus due to excessively high utilization and the resulting bottlenecks. Any squeeze on profits due to high demand for labor and high wages [cf. Devine, 1987] would be reflected not in ** u**, but in

Note that if ** u** = 1, then Y = Z and R/Y = R/Z =

where ** k** is the capital-capacity ratio (K/Z). The variable

Next assume a Kaleckian consumption function where all wages are consumed but only part of surplus:

C = W + (1 - < 1= (1 - aas^u) Yb |

where (B-5) is derived from (B-4), (B-2), and (B-1).

Total demand (which in equilibrium equals net income, Y) depends not only on C but on planned net investment (I) in the leading sector and external demand (E). E is "net exports" to other (non-leading) sectors, including the demand-side benefits of fiscal stimulus received by the leading sector. Thus, from (B-5):

Y = E + I + C = E + I + (1 - ) Yb |

Solving for Y:

Y = (E + I)/( |

By definition, capacity utilization is

Therefore, from (B-7) and (B-8),

Using v as a proxy for u,

This is negative since both ** v** and

In the stock-adjustment model, desired net investment is

(B-12) |

In the first part of this equation, Kd is the desired stock of means of production, Kold is the stock of these goods left over from the previous period, and **§** is the stock-adjustment coefficient. In the second part, *k**d* is the desired capital-output ratio at full capacity utilization, Yex is the expected level of demand, ** k** is the actual capital-output ratio at full capacity utilization, and Zold is full-capacity output in the previous period. This equation can be restated as the desired rate of growth of the capital stock:

The interaction of the conditions for stable growth (part 1) and the actual determination of the growth rate (part 2) is relatively complex. Only a simple version is considered here. Assume that ** b** = 1, so that

The denominator of (B14) must be positive for the product market equilibrium to stable (investment responds less than does saving to changes in capacity utilization). So

A rise in ** r*** can hurt capacity utilization if
