Alcock and Newcombe:  The Perception of National Power

Alcock, Norman Z., and Alan G. Newcombe. “The Perception of National Power.” The Journal of Conflict Resolution 14, no. 3 (September 1, 1970): 335–343.

"...if international relations is to become a science it will have to establish a definitive quantitative measure for its most basic variable--national power" (335).

"There may be differences between 'real' power and 'perceived' power.  Given some objective level of 'real' power, a nation may nevertheless be perceived as stronger, or weaker, y the people of another nation.  Yet both objective and subjective power must ber based on a number of measurable facts.  The purpose of this empirical study is to ascertain these measurable facts and thus help to establish a quantitative definition of national power.  In addition to its theoretical value, a quantitative measurement of power can have an immediate practical application for peace--that is, in devising formulas for weighted voting in the United Nations, which is now floundering on the 'one nation, one vote' principle" (335).  

They survey folks asking them to rank countries by "importance".  This is the dependent variable for their analysis.  

"We conclude, therefore, that perceived national power is some function of GNP or military expenditure (in purchasing-power-equivalent dollars) if none of the nations has been at war recently, but is a function of military expenditure alone if warring nations are included in the rating"  (342).

Two regressions that are salient:  Relative Power = -8.85 + 0.67 population + 0.47 GNP/cap

Relative power = 9.4 - 0.09 population + 0.93 GNP

Kugler and Arbetman:  Choosing Among Measures of Power

Kugler, Jacek, and Marina Arbetman. “Choosing Among Measures of Power:  A Review of the Empirical Record.” In Power in World Politics, edited by Richard J Stoll and Michael Don Ward. Boulder, Colo: L. Rienner Publishers, 1989.

"We show that, for major powers, a number of indicators used in international politics to index power are highly related.  Whether one chooses to use GNP, the COW Indexes, or adjust these for military expenditures is not critically relevant for the analysis of relations among major powers over time.  This choice affects cross-sectional analysis since rank varies at one point in time but even here the average disparity is on the order of 10%" (73-4).

Merritt and Zinnes:  Alternative Indexes of National Power

Merritt, Richard L, and Dina A Zinnes. “Alternative Indexes of National Power.” In Power in world politics, edited by Richard J Stoll and Michael Don Ward. Boulder, Colo.: L. Rienner Publishers, 1989.

"Our task is threefold   first, to summarize the more prominent indexes of power that researches have proposed, highlighting both similarities and differences; second, to compare the empirical consequences of these alternative approaches; and third, to explore the implications of these findings" (12).  They define power in line with what others have said, "...how probable it is that X can exert d amount of influence over Y with respect to issue g" (12).

Referring to single variable models of power:  "A high national income...can imply a country's long-term ability to influence others, but not if it means that the population is less willing and even less able than others to engage in activities such as wars that might jeopardize its high standard of living.  A healthy, skilled population may be a capability; an equally large but disease ridden and illiterate population can diminish the government's capacities.  General s never tire of telling us that even the best-equipped army is ineffective without good leadership and high morale.  Is energy used to drive television sets and compact-disk players equivalent to energy used for industrial production?  Without strong evidence that a single-variable indicator predicts..relevant outcomes,k it is difficult to answer the complaints of 'realists' who point to a more complex world than any single indicator suggests" (14).

They list various contributions to measurements of power:

Knorr:  very early, measured potential military power

Alcock and Newcombe:  interested in perceptions, used Russet 1968 (in Singer Quantitative International Politics).  Find three equations that can be used to assess relative power.  The two they like are:

Relative Power = -8.85 + 0.67 population + 0.47 GNP/cap
Relative power = 9.4 - 0.09 population + 0.93 GNP

Singer:  COW.

Demographics:  Total population and urban population
Industrial:  energy consumption and iron and steel production
Military:  total spending and size of military

Fucks:  non linear formulas that combine population, energy, and steel.  In German.  "Fucks predicts that growth in US power will taper off and reach 200 [base 100 US in 1960] by 2040.  Meanwhile, China's power will outstrip that of the United States in about 1975 and reach a score of approximately 3000 in the year 2040" (17).

Cline:  measures "capabilities" (population, territory, income, resource production, military capabilities) as well as "commitment" (national strategy, national will).

German:  non-linear, and influenced by possession of nuclear weapons.
