Abstract

Purpose

The purpose of this paper is to investigate the relationships between environmental consciousness (ECO), green purchase attitude (GPA), green purchase intention (GPI), perceived customer effectiveness (PCE), green behaviour (GRB) and green purchase behaviour (GPB). Based on the statistical analyses, this paper offers some further research directions to advance the extant literature.

Design/methodology/approach

The theoretical model is firmly grounded in extant literature. To test the study hypotheses, the authors have developed a survey instrument following a two-stage process. The constructs were first operationalized by the authors and then pre-tested by experts. Dillman’s (2007) guidelines were then followed to gather data. Finally, the theoretical model was tested using multivariate statistical tools.

Findings

Results indicate that ECO has an influence on GPA and PCE; GPA has an influence on PCE and GRB; GPI has an influence on PCE; and GRB has an influence on GPB. Environmental benefit still ranks at the sixth position among eight product-selection criteria, as is evident from qualitative in-depth interviews indicating a primarily rationalistic and not an altruistic purchase approach. The gap in translation of ECO into GB and GPB can be attributed to costliness, non-availability with less variety, lack of brand reputation of green products and budget constraints for customers.

Research limitations/implications

The study faces the limitation of generalizability of the results because it was carried out in a particular state in India; it may not be the perception of the country as a whole. The bias owing to social desirability, selective memory and telescoping with the use of self-reported data could also be a limitation for the current empirical study.

Originality/value

This study aimed to extend pro-environmental behaviour studies beyond developed countries and to empirically validate the models built on the theory of ECO leading to GPB, especially for India, a rising market. A novel approach to empirically discuss the situational and market factors will provide a much-needed thrust for research on these lines.

Abstract

Companies have traditionally relied on taking advantage of price‐quantity discount (PQD) on large purchases. With the adoption of just‐in‐time (JIT) philosophy companies are encouraged to purchase materials in small lots to synchronize production with deliveries. This raised a question whether PQD is applicable in a JIT purchasing environment. Argues that though seemingly inconsistent, JIT and PQD can coexist. Develops an integrated JIT‐PQD model to allow a buyer to decide how much to purchase and how many shipments be placed per order.

Abstract

This paper discusses about the enterprise resource planning (ERP) market in India and the world. The current extension of ERP is e‐CRM. The ERP market has become saturated and is on the decline; and emerging from it is the market for small and medium scale enterprises. ERP, especially in India, is being offered by small‐localized players to small and medium sized firms customizing it to the needs and their pockets. Taking this cue, the big ERP players have also started offering complete solutions to the small firms. The paper illustrates this point by using the case example of Prathma, a modern blood bank in India. Prathma has been the first blood bank in India to use ERP to integrate its functions using a customized ERP. This has installed a quality check in its day‐to‐day operations and has significantly lowered costs. The findings of this study indicate that ERP systems promises benefit from increased efficiency to improved quality, productivity, and profitability.

Abstract

Purpose

The purpose of this paper is to explore the dimensions of Indian manufacturing firms’ competencies and to study the impact of these competencies on firm performance.

Design/methodology/approach

The authors have adopted a literature survey to identify variables and gaps in the research. Based on the construct and its item identified through the literature review the authors have developed a structured questionnaire which was pre-tested before being used for the final survey. The authors have collected data from 100 firms out of 275 targeted firms in two phases which represents a 36.36 per cent response rate. The data have been subjected to exploratory factor analysis (EFA) using varimax rotation, which reduced the data into seven parsimonious and orthogonal factors. The authors then carried out regression analysis using EFA output to test the relationship between six independent variables, representing competencies of the firm and performance.

Findings

Findings show that EFA has reduced the data into seven factors, out of which six represent firm competencies and one represents firm performance. The competencies which have been identified are supply-demand coordination and product pricing, logistics, marketing, procurement, manufacturing simplicity and product quality and preventive maintenance. The EFA output was further tested using multiple linear regression analysis which shows that out of six competencies, four are positively supporting, except procurement which is negatively supporting and logistics which is found to be statistically insignificant.

Research limitations/implications

The conclusive model suggests that there is considerable impact from other deterministic variables which are not assumed in the present study, and some of the variance has been accounted for by stochastic variables and response error. However, utmost care has been taken to minimise response error by personal follow-up with each of these firms. The outcome of the quantitative analysis provides an insight into firm competencies and their impact on firm performance. It is very important for the managers who are interested in deriving superior performance from their firm and focusing on supply-demand coordination and product pricing, manufacturing simplicity, marketing and product quality and preventive maintenance practices.

Originality/value

This original study has been carried out by researchers in India on Indian manufacturing firms and adopted an EFA technique to identify dimensions which are unique in their contribution.

Abstract

Evaluative studies of OD applications 1950–86 generated an earlier panel of 100 applications with a substantial success rate, and this article reports that extending the period of observation in economically‐developing countries does not require substantive modification of that estimate. Additional cases were sought during the 1987–1993 interval, to augment the 30‐plus year period underlaying the original panel. The augmented panel has been enlarged by approximately 20 percent—from 100 to 121 cases of applications.
