⁶ Ibid., 444. Gurr has found a positive relationship between the exclusion from economic opportunity of social groups on the basis of ascribed characteristics and political violence. See Gurr, Ted, “A Causal Model of Civil Strife: A Comparative Analysis Using New Indicators,” American Political Science Review, lxii (December 1968), 1104–24CrossRefGoogle Scholar. The Gurr measure characterized as “economic discrimination” might also be interpreted as an indicator of the distribution of wealth in society.

⁷ The provinces of the Central Highlands have been excluded from the Mitchell analysis. A listing of the included provinces can be found below in footnote 16.

⁸ We shall also report t statistics, even though we are dealing with a population and not a sample.

⁹ Precise definitions of the variables, the original data sources, and the data matrix can be found in Mitchell (fn. 1), 425–30. Variables found to be unimportant were per capita rice production, ethnic composition, and region.

¹⁰ The variables M and PD will be included in subsequent analyses, even though they will not be treated substantively. Criticisms of the construction of M are in Paige, Jeffrey M., “Inequality and Insurgency in Vietnam: A Re-Analysis,” World Politics, xxiii (October 1970), 24–37CrossRefGoogle Scholar; and Samson, Robert, The Economics of Insurgency in The Mekong Delta of Vietnam (Cambridge, Mass. 1970), 231–32Google Scholar. The sign of the coefficient of M leads to the counter-intuitive conclusion that more mobility implies less GVN control. The positive sign of PD is interpreted to indicate that areas of population concentration would be “easier for a conventional army and police force to protect.” Mitchell (fn. 1), 435.

¹³ Computed from figures given in Stanford Research Institute, ibid., I, Part 2, B73. Slater (fn. 2), 729–31, suggests that the post-1968 pace of the redistribution of FL has greatly increased. The evidence for the period of concern, however, seems to con-firm Mitchell's position concerning the redistribution of this land.

¹⁶ Misspecification and identification are concepts used in econometric work. The first case implies that relevant variables have been excluded from the model. Samson (fn. 10), 232, and Paige (fn. 10), 33–34, have suggested problems of this nature resulting from the omission of certain geographic and historical factors. Faulty identification in models of this type (reduced form) refers to situations in which the independent variables arc not truly predetermined or the dependent variable is itself a cause of one or more of the independent variables. Samson has argued that the relationships observed by Mitchell could be explained by the hypothesis that causality runs from GVN control to the land tenure variables (232). The values of the land tenure variables are not determined “independently” of the extent of GVN control. A discussion of misspecification and identification can be found in Goldberger, Arthur S., Econometric Theory (New York 1964), 194–200, 306–18Google Scholar.

¹⁷ Provincial boundaries arc for the year i960. Nordiern Coastal Lowlands: Quang Tri, Thua Thien, Quang Nam, Quang Ngai, Binh Dinh, and Phu Yen.

Mekong Delta: An Giang, An Xuyen, Ba Xuyen, Dinh Tuong, Kien Giang, Kien Hoa, Kien Phong, Kien Tuong, Long An, Phong Dinh, Vinh Binh, Vinh Long. Soudiern Plateau: Tay Ninh, Binh Puong, Bien Hoa, Long Khan, Phouc Tuy. Paige (fn. 10), 31.

²⁰ Paige (fn. 10), 31–32, suggests an economic interpretation of this indicator for one region, the Northern Coastal Lowlands.

²¹ Regional totals of expropriated land were computed by Paige, ibid., 30. A similar ranking of the rice regions can be obtained by aggregating hamlet-level data for the difference between net income and expenditures into regional means.

²² Samson (fn. 10), 234, argues this position for the Delta. It is in all probability equally true for the other agricultural regions of Vietnam.

²⁹ The coefficient of OOL for the mixed rubber-rice culture of the Southern Plateau is b ₁. This coefficient is clearly negative in equations (4)–(6). An interpretation which would be consistent with our argument, but for which no data are available, is the speculation that in this region an individual farms if he cannot become a plantation worker. Being a plantation worker would be a superior economic opportunity. OOL in this region would then be a negative indicator of peasant wealth.

³⁰ Zagoria, Donald S., in “The Ecology of Peasant Communism,” American Political Science Review, lxv (March 1971), 149–50Google Scholar, suggests that if landowners perform some indispensable function they need not be resented. He argues that “In regions of large-scale capitalist enterprise, on large plantations, or under any conditions where it is perfectly clear to the landless that they have neither the skills nor the capital to replace the landowner, inequities are not likely to be a source of great resentment”
