An experimental approach to segmenting buyers of marketing research

Successful industrial market segmentation may often depend on the marketer's ability to identify key characteristics influencing purchase preferences. Environmental, organizational, and personal factors are all potential determinants of buyer response patterns. Recent attention to microsegmentation processes has focused interest on personal level factors and how these are modified by organizational and situational variables. Utilizing a simulated buying experiment, this study explores a simplified approach to microsegmentation that emphasizes information readily available to industrial vendor representatives.     

Segmenting buyers in different types of organizations

Organizational type is presented as a potentially important company specific characteristic that affects the organizational buying process. Factor analysis and multiple discriminant analysis are utilized to demonstrate that differences in the importance associated with purchasing related factors exist among purchasing managers from commercial, non-for-profit, and government organizations. Finally, the managerial usefulness of organizational type as a macrosegmentation variable is discussed.

Capital budgeting and uncertain inflation

In this article, capital budgeting is examined under uncertain inflation. The market value of a risky asset is shown to be greatly influenced by uncertain inflation. Risk- adjusted discount rates and certainty equivalent factors are determined by risks due to potential changes in investors' expectations in response to changes in the unanticipated inflation rate and market conditions over time. A serious error in capital budgeting decision may be resulted if the impact of uncertain inflation is ignored in the valuation process.     

Inventories,credit transactions,and the marginal effective tax rate

It is observed that marginal effective tax rates (METR), as conventionally calculated, can only consider working capital requirements to a limited extent. A formula is derived to incorporate inventory requirements into the calculation and, via a numerical example, it is shown that such an incorporation can radically alter METRs from those conventionally calculated. The analysis is extended to credit transactions without affecting the above conclusion. Thus, if METRs are to be used as a means of evaluating the effects of tax policy on the incentive to invest, working capital requirements need to be explicitly allowed for.     

Developing an empirical socioeconomic typology of counties in five western states

County-level data representing a broad range of socioeconomic variables were obtained for the 190 counties in five western States-California, Colorado, Nevada, Utah and Wyoming. A factor analysis of these variables produced eight orthogonal factors: (1) Urbanism, (2) Poverty vs affluence, (3) County tax revenues and services, relative to population, (4) Proportion of aged population, (5) Social stability vs instability, (6) New housing development vs cattle ranching, (7) Crop farming, welfare and unemployment, and (8) Small business activity vs level of federal employment. Several ways of examining scores on these factors were explored and demonstrated: distributions of scores on individual factors across counties were displayed graphically; individual county profiles, comprised of scores on all eight factors, were produced and examined; and groups of counties with similar profiles (representing county “types”) were identified through cluster analysis, and their average profiles and geographic distributions displayed and discussed. Groupings of clusters which were similar in some respects and varied in others were also presented. The utility of these methods for planning activities which may involve individual counties and/or groups of counties is discussed.
