Influence of virtual communities in purchasing decisions: The participants' perspective

This study intended to fill some gaps in knowledge about virtual communities and their influence on consumers' purchasing decisions. A Brazilian Orkut community, whose central theme is preparing for wedding ceremonies, was investigated to reveal relationships among members and group influences on purchasing decisions. Twenty-one interviews were conducted by telephone. Results unveil a basic code of conduct, suggesting that the community can also act as a normative reference group, with strong identification among participants. Although the central interest – the wedding ceremony and party – could be considered as episodic, many members actively stay in the community after being married, just to help others. Group leaders seemed to be active participants, those with more experience with products related to the group's interests, or those perceived as having refined tastes. There was evidence that purchasing intentions and behavior can be altered as a result of interactions among members.     

Testing the impact of trading volume on market return and volatility： The case of the Romanian stock market

This paper examines both the return-volume and volatility-volume movements on Bucharest stock exchange, in order to evaluate the impact of changes in stock market liquidity on stock returns and on volatility of returns. We employ linear Granger-causality tests to investigate the dynamic relation between trading volume, stock returns and returns volatility on the Romanian stock market, using daily logarithmic returns for the composite index BET-C, as a proxy for the market, and daily logarithmic change in trading volume during the period January 2004-July 2008. As a proxy for return volatility we employ absolute values of daily deviation of return from its mean value during the considered time period. We can report unidirectional linear causality from returns to volume and also from volume to volatility.     

What can eastern European countries learn from the Slovak economy? A twin deficit growth approach

This paper applies an extended growth model to the Slovak economy and explains the potential pitfalls that a transition economy faces on the way to converging with other advanced European countries. Our empirical analysis shows that Slovakia grew at a higher rate than that allowed by the balance-of-payments equilibrium rate and that this is consistent with the accumulation of trade deficits over time. A scenarios analysis shows that improving trade competitiveness, changing import and export shares toward a current account balance, and financing the economy at a lower cost will be the most successful ways to achieve higher growth.     

Fiscal Forecasting: Lessons from the Literature and Challenges*

While fiscal forecasting and monitoring has its roots in the accountability of governments for the use of public funds in democracies, the Stability and Growth Pact has significantly increased interest in budgetary forecasts in Europe, where they play a key role in EU multilateral budgetary surveillance. In view of the increased prominence and sensitivity of budgetary forecasts, which may lead to them being influenced by strategic and political factors, this paper discusses the main issues and challenges in the field of fiscal forecasting from a practitioner's perspective and places them in the context of the related literature.     

Firm growth and liquidity constraints: evidence from the manufacturing and service sectors in Italy

We use a large firm-level panel data set to analyse the relevance of liquidity constraints on firm growth in Italy. In most European countries, mainstream financial institutions are scantly able to provide affordable credit facilities to small firms. Thus, these firms are forced to finance their growth almost exclusively through retained earnings. We estimate a dynamic version of Gibrat-law, incorporating cash flow as a measure of financial constraints, for two different size classes within small and medium size enterprises and for several industries in manufacturing and service sectors. The findings show that, in general, small manufacturing firms have higher growth-cash flow sensitivities with respect to medium firms. Conversely, our results highlight, for the services, a significant heterogeneity in the impact of liquidity constraints on firm growth. In particular, the sensitivity of growth rates to the cash flow appears relatively high for small firms belonging to Knowledge Intensive Business Services. Validation of Gibrat-law in the services suggests that an important group of industries, with a superior capacity of encouraging firm’s competitiveness, need more financial resources to promote their growth and that of the manufacturing sectors with whom they are connected.     

The low effect of perceived risk in the relation between hedonic values and purchase intention

ABSTRACT

This research seeks to identify the influence of perceived risk in the purchase intention environment regarding innovative technological products, and also to understand how brand trust reduces the expected impact of this risk due to the hedonic and utilitarian characteristics influencing purchase intention. Quantitative research was carried out and analysed through structural equation modelling, where the influence of perceived risk on utilitarian value and purchase intention was identified, as well as the influence of brand trust in reducing this risk. The conceptual implications of the study describe as the perceived risk moderates hedonic features less compared to utilitarian features regarding purchase intention, thus demonstrating that emotional relationships are less affected by this risk. The managerial implications suggest that devices with utilitarian characteristics should be more carefully planned according to their brand and complexity, while hedonic products do not require brand trust to guarantee consumers’ purchase intention in the current innovative scenario.     

Business strategy for sustainable development: Impact of life cycle inventory and life cycle impact assessment steps in supply chain design and planning

Sustainability reporting has become a central instrument in displaying a company's strategy and engagement with a more sustainable society. Life cycle assessment (LCA) is an important tool in this context as it is aimed to analyze the entire life cycle of the product/service, instead of focusing on one focal firm. However, the lack of standardized guidelines in its application raises questions regarding the usefulness and validity of results. This study contributes to the improvement of sustainability reporting through the identification of the uncertainty sources in life cycle methodologies that have the biggest impact in the definition of business and environmental strategies, exploring a supply chain‐oriented analysis. The focus is on life cycle inventory (LCI) and life cycle impact assessment (LCIA). A multiobjective optimization‐based methodology is applied to a supply chain case study in the pulp and paper industry. Environmental and economic objectives are considered. Results show that different LCIA methods and different normalization data sets result in significantly different business and environmental strategies. However, different system models and cultural perspectives at the LCI step and variations in the characterization factors tend to lead to the same decisions. Important insights are gained regarding the impact of nonstandardized analysis of the application of LCA in supply chain design and planning decisions and consequently on business strategy definition and sustainability reporting. Furthermore, the importance of operations research methods to improve LCA‐based studies and of bridging the gap between LCA and supply chain management bodies of knowledge is highlighted in this work.     

Excess Burden of Taxation and Environmental Policy Mix with a Consumer‐Friendly Firm

This study examines the environmental policy mix of tradable emission permits and emission taxes in a duopoly model with a consumer‐friendly firm. We analyse the interplay of the two policies and the welfare consequences in the presence of excess burden of taxation. We show that an emission tax can be redundant when both the excess burden of taxation and the degree of consumer friendliness are insignificant. However, when the excess burden of taxation is significant, tradable permits policy with tax treatment should be applied to enhance welfare in the presence of a consumer‐friendly firm. Finally, under the tax revenue‐neutral case where the excess burden of taxation does not matter, the environmental policy mix is also efficient if the degree of consumer friendliness is sufficiently high.     

Service industries,growth dynamics and financial constraints

This work represents a first attempt to study the effects of financial constraints on firm growth within the business services as it can be argued that firms are different not only in terms of size but also in the way they operate in a specific industry. Thus, firms can be either characterized by the use of intensive professional knowledge or, alternatively, by the use of a workforce with no specific professional skills. For the business services included, the results reveal the relative importance of internal sources of financing with respect to the external ones. The liquidity constraints mainly affect the growth of industries requiring qualified labor pool, such as computer programming and information service activities, as well as the professional and scientific ones. In these sectors, foremost operate small firms with a superior innovation capacity; therefore, they are considered risky and face difficulties in raising debt capital on favorable terms.     

Nascent Entrepreneurs' Motivations in European Economies: A Gender Approach Using GEM Data

ABSTRACT

Entrepreneurship is becoming an important source of employment for women in many countries. There are different circumstances and motives that contribute to the decision to start a business. In this study, we developed a model that can estimate the probability of individuals becoming nascent entrepreneurs by opportunity or necessity. The model considers individuals' sociodemographic characteristics and European economies' perceived characteristics as oriented towards efficiency or innovation. Statistical logistic regression was used to test the model. The results show statistically significant differences between genders, European economies oriented either to efficiency or innovation, and entrepreneurs who are born out of opportunity or necessity.
