Green consumer market segmentation: empirical findings from Portugal

Concern with environmental degradation has led to a new segment of consumers: the green or ecological consumers. Marketers must pay special attention to the needs of this segment. The growing concern with the environment, increased competition and greater selectiveness and demands of consumers represent an immediate challenge for green marketing. This paper aims to identify distinct market segments based on several environmental variables. It also investigates individuals' behaviours and perceptions about green consumerism. The used methodology was the collection of primary information through a direct survey. The study covered 887 Portuguese consumers, aged over 18. The results show that certain environmental and demographic variables are significant in differentiating between the ‘greener’ consumer group and the other segments. Portuguese consumers, despite their support for policies designed to improve the environment, do not always translate their concerns into environmentally friendly actions. Possible implications of these results for firms' marketing strategies are also discussed.     

R&D,Innovation and Knowledge Spillovers: A Reappraisal of Bottazzi and Peri (2007) in the Presence of Cross‐Sectional Dependence

Bottazzi and Peri (Economic Journal 2007; 117 : 486–511) show the existence of a cointegrating relationship between the domestic stock of knowledge, domestic R&D and the international knowledge stock for a panel of OECD countries and interpret it as evidence supporting the semi‐endogenous versus the endogenous growth theory. We replicate the baseline specification of their study and we show that main results are robust to the use of a different estimation strategy (Bai et al., Journal of Econometrics 2009; 149 : 82–99) that duly takes into account cross‐sectional correlation: interestingly, in this case we also find a larger role for knowledge spillovers.

EURO CORPORATE BOND RISK FACTORS

This paper investigates the determinants of credit spread changes in euro‐denominated bonds. We adopt a factor model framework, inspired by the credit risk structural approach, as credit spread changes can be easily viewed as an excess return on corporate bonds over Treasury bonds. We try to assess the relative importance of market and idiosyncratic factors as an explanation of movements in credit spreads. We adopt a heterogeneous panel with a multifactor error model and propose a two‐step estimation procedure, which yields consistent estimates of unobserved factors. The analysis is carried out with a panel of monthly redemption yields on a set of corporate bonds for a time span of 3 years. Our results suggest that the euro corporate market is driven by observable and unobservable factors. The unobservable factors are identified through a consistent estimation of individual and common observable effects. The empirical results suggest that an unobserved common factor has a significant role in explaining the systematic changes in credit spreads. However, in contrast to evidence regarding US credit spread changes, it cannot be identified as a market factor. Copyright © 2011 John Wiley & Sons, Ltd.     

Macroeconomic environment,country risk and stock market performance: Evidence for Brazil

The paper aims at providing empirical evidence about (i) the influence of macroeconomic variables and economic policies on country risk and (ii) the influence of macroeconomic variables and country risk on the main Brazilian index of the stock market (Ibovespa). The study analyzes the role that macroeconomic fundamentals plays, but also the role that the credibility of the regime of inflation targeting and the reputation of the central bank play in lessening country risk and in the improvement of the stock market performance. The empirical evidence was obtained through the application of ordinary least squares (OLS), generalized method of moments (GMM) and GMM systems. The results found suggest that monetary policy and public debt management, as well as credibility and reputation affect country risk and the performance of the Brazilian stock market.     

Economic role, Property rights, Labour skills and Technology in the Portuguese Wine Co-Operatives

Agricultural markets are characterised by thinner margins, greater price and income volatility. Despite these changes, agricultural raw material markets are increasingly characterised by the vertical co-ordination of farmers and processors. The organisational form of a marketing co-operative is a common means adopted by farmers to achieve this end. In a world increasingly concerned with the importance of the separation of ownership and user, the survival and growth of agricultural co-operatives (in which the primary users of the services are also the main owners) is linked to their economic role, to how members exercise their property rights, and how inputs are used by the co-operative. This paper provides a function that summarises the economic role of agricultural co-operatives and goes on to analyse the contribution to the economic performance of Portuguese wine co-operatives (PWCs) made by the use of property rights, and the skills of the human resources and technology employed. The results of a multinomial logit model show that PWCs would indeed be able to improve their economic performance through the application of integrated management strategies to solve common property and horizon problems, as well as increasing their recruitment of skilled professionals in the areas of management, wine production and marketing, and by the adoption of new technologies of production and packaging.     

Mortgage lending on Native American reservations: Does a guarantee matter?

The Section 184 Indian Home Loan Guarantee Program provides lenders with a 100 percent guarantee for mortgage loans to Native Americans residing on reservations belonging to tribes that have chosen to participate in the program. We find that Native Americans residing on trust land whose tribes have adopted Section 184 have a marginally statistically significantly higher loan approval rate than Native Americans residing on trust land whose tribes have not adopted Section 184. However, the statistical significance disappears once tribe fixed effects are included in the analysis, suggesting that underlying tribe characteristics correlated with the adoption of Section 184 are more important determinants of access to credit than is Section 184 per se.     

Asymmetric search and prospect theory: choice experiment on consumer willingness to search in the gasoline retail market

We use an internet survey conducted among a representative random sample of drivers in the State of Ohio consisting of a choice experiment designed to examine the mechanism driving asymmetric search. The internet survey affords us the opportunity to overcome endogeneity difficulties by imposing exogenous price changes on gasoline consumers to examine the decision-making process behind intended search decisions. We randomly assigned participants to one of five price treatments (either 2.5 or 5% above or below their reported expected price, or no change). We provide a simple empirical model to derive testable implications under prospect theory and use the internet survey to test them. Results indicate that among the respondents who faced prices below their expected price, only 12% chose to search, whereas 45% searched when prices were above. Further, we find results consistent with asymmetric search being driven by prospect theory. The change in consumers’ willingness to search is twice as large when prices exceed expectations by 2.5% relative to when prices exceed them by 5% suggesting that consumers derive utility of finding a good deal evaluated relative to a reference price. We show that this result is inconsistent with standard utility theory or consumers using alternative reference prices.     

An exploratory study on the returns management process in an online retailer

The returns management process is gaining increasing importance both in academia and among supply chain professionals, not only as a tool in the practice of sustainability, but also for its strategic role in many economic sectors. Several studies show how efficiently returns management can reduce costs and provide a competitive advantage to companies. Likewise, electronic commerce, or e-commerce, has shown significant growth in many countries and, due to its very nature, it presents much higher return rates than traditional trade. However, despite the importance of returns management operation for electronic commerce, few studies explore this theme in the literature. The aim of this paper is to describe the process of returns management of the largest online retailer of the Brazilian market, showing its evolution and analysing its performance, as well as identifying its main shortcomings. We conclude with suggestions for improvements and the implementation of a more efficient system.
