Beef Credence Attributes: Implications of Substitution Effects on Consumers’ WTP

Consumers’ food choices are influenced by a wide variety of credence attributes, but the food industry faces problems assessing whether the price premiums that consumers are willing to pay for these attributes will be sufficient to offset higher production costs. In this context, consumers’ willingness to pay (WTP) for safer, cleaner and animal friendlier beef was investigated through a choice experiment. The relative importance of WTP for these attributes shows that consumers place the highest values on food safety, followed by animal welfare and finally environmental protection. WTP for different combinations of the three attributes cannot be obtained by independent valuation and summation due to the presence of significant substitution relationships. However, some suggestions for the relationships between these attributes can be proposed through an after‐survey analytical solution. The bias involved in separately valuing closely related attributes can potentially jeopardise the success of a differentiation strategy.     

Voluntary adoption of International Financial Reporting Standards by large unlisted companies in Portugal – Institutional logics and strategic responses

Common explanations for the voluntary adoption of International Financial Reporting Standards (IFRS) have been based on economic efficiency arguments. This paper introduces new theoretical arguments to explain how institutional pressures influence decisions to adopt IFRS voluntarily. Through recourse to an institutional theory context, we combine the analytical framework proposed by Oliver (1991) with the concept of institutional logics, and apply this framework to the financial accounting field for the first time. This combined model shows how multiple forms of rationality constrain company responses to pressures to adopt a new accounting regime.     

The stability–concentration relationship in the Brazilian banking system

In this article, the relation between non-performing loans (NPL) of the Brazilian banking system and macroeconomic factors, systemic risk, and banking concentration is empirically tested. In evaluating this relation, we use a dynamic specification with fixed effects, while using a panel data approach. The empirical results suggest that the banking concentration has a statistically significant impact on NPL, suggesting that more concentrated banking systems may improve financial stability. These results are important for the design of banking regulation policies.     

Factors Influencing Social Responsibility Disclosure by Portuguese Companies

This study compares the Internet (corporate web pages) and annual reports as media of social responsibility disclosure (SRD) and analyses what influences disclosure. It examines SRD on the Internet by Portuguese listed companies in 2004 and compares the Internet and 2003 annual reports as disclosure media. The results are interpreted through the lens of a multi-theoretical framework. According to the framework adopted, companies disclose social responsibility information to present a socially responsible image so that they can legitimise their behaviours to their stakeholder groups and influence the external perception of reputation. Results suggest that a theoretical framework combining legitimacy theory and a resource-based perspective provides an explanatory basis for SRD by Portuguese listed companies.     

Equity-premium prediction: Attention is all you need

Predictions of stock returns are greatly improved relative to low-dimensional forecasting regressions when the forecasts are based on the estimated factor of large data sets, also known as the diffusion index (DI) model. However, when applied to text data, DI models do not perform well. This paper shows that by simply using text data in a DI model does not improve equity-premium forecasts over the naive historical-average model, but substantial gains are obtained when one selects the most predictive words before computing the factors and allows the dictionary to be updated over time.
