An analysis of the construct “involvement” in consumer behaviour

The aim of this paper is to analyse the construct involvement. Specifically, the present work extends the sphere of study of the construct involvement at brand level, applying it to Denominations of Origin (D.O.s). Hence, after an overview of the concept, it suggests a cognitive approach to the measurement of involvement. It proposes as indicators the number of values associated with this designation, the centrality of these values and the intensity of the association. In this delimitation of the concept, a model is presented that is set within the framework of an analysis of the decision-making process adopted by consumers when purchasing wine. This postulates that temporary involvement with a D.O. has explanatory power, as does the direct effect of the regular outcomes of a permanent involvement with such a designation on the process in question. In addition, a correlation is proposed between the state of temporary involvement with a D.O. and the continuing consequences of a permanent involvement with this designation.     

Conditional mean functions of non-linear models of US output

We compare a number of models of post War US output growth in terms of the degree and pattern of non-linearity they impart to the conditional mean, where we condition on either the previous period's growth rate, or the previous two periods' growth rates. The conditional means are estimated non-parametrically using a nearest-neighbour technique on data simulated from the models. In this way, we condense the complex, dynamic, responses that may be present in to graphical displays of the implied conditional mean.

Using reputation for corporate sustainability to tackle banks digitalization challenges

The new landscape in the financial sector, characterized by fierce competition and the entrance of new technological players, has forced banks to speed up their digital transformation. However, for banks, digitalization entails challenges that can hinder the potential benefits and compromise their survival. In this context, we argue that the reputation generated by corporate sustainability (RCS) may offset these digitalization drawbacks. In particular, we find that the combination of RCS and digitalization facilitates in transforming the organizational nature of banks by simultaneously narrowing their boundaries and expanding their scope. We empirically confirm our hypotheses by analyzing a panel of 110 multinational banks from developed countries.     

The relevance of commuting zones for regional spending efficiency

We use data envelopment analysis (DEA) efficiency scores to show that clustering municipalities into encompassing regional clusters improves spending efficiency of single stand-alone municipalities. We propose a new geographic aggregation based on municipalities-to-municipalities commuting flows, defined using hierarchical cluster analysis. Our example for Portugal shows that from an output-oriented perspective between 83% and 98% of municipalities would increase their efficiency scores, while from an input-oriented perspective between 86% and 98% of municipalities would also be better off in terms of efficiency. Then using a linear regression model, we find that population increases positively affects the efficient scores (via scale economies). Also, increases in the share of high-educated and poorer residents leads to higher efficiency scores.     

Economical evaluation of greenhouse layout design

This paper offers mutual exchange of knowledge and expertise between agriculture and production-economy by economical evaluation of greenhouses. Greenhouses are Hi-Tech horticulture farms, in which advanced technological infrastructure increase production efficiency by providing optimal growing conditions. However, this infrastructure involves high capital investments. There are other cost sources, of which labor is dominant, generally in horticulture and in greenhouses in particular. Efficient use of space and labor are often conflicting goals in greenhouse layout design. In this paper, these conflicts are presented and illustrated, and tools are developed to evaluate layout design by the resultant annual operational profit, thus enable comparison of alternative layouts. To increase accessibility, spreadsheet software is used for the calculations. Further, the spreadsheet is designed to support WHAT-IF analyses. The applicability of the proposed approach is demonstrated via numerical analyses of layout design of an actual greenhouse for pepper growing using the Holland method. Evidently, the layout design can have significant effect on the economical efficiency of the greenhouse—annual profit increases by, at least 12%, and up to 40%! The tradeoff between space utilization and resource utilization; e.g., labor, is common to all greenhouses, whether vegetables, flowers or other plants are grown in them and the tools presented herein can be easily modified to any desired case.     

Agricultural commodities pricing model applied to the Brazilian sugar market

This article suggests a pricing model for commodities used to produce biofuel. The model is based on the concept that the deterministic component of the Wiener process is not constant and depends on time and exogenous variables. The model, which incorporates theory of storage, the convenience yield and the seasonality of harvests, was applied in the Brazilian sugar market. After predictions were made with the Kalman filter, the model produced results that were statistically more accurate than those returned by the two‐factor model available in the literature.     

Dependent care and the workplace: An analysis of management and employee perceptions

This study attempts to identify differences in the perceptions of top management (defined as CEOs, directors, and presidents) and employees (defined as middle and supervisory management) regarding (a) the effects of dependent care responsibilities on job performance, and (b) the extent of a firm's responsibility in providing support for those faced with caring needs concerning eldercare, childcare, substance abuse, and mental/physical handicaps. The results indicate that these two groups have significantly different perceptions of the effect of dependent care responsibilities on job performance, and on the firm's responsibility in providing support for three types of dependent care.     

Accounting Standards Harmonization and Financial Integration

We empirically examine whether adopting a uniform set of accounting standards mitigates information frictions in financial markets and facilitates market integration. Using a difference‐in‐difference design, we find that after the mandatory adoption of IFRS local stock returns incorporate more global information and at a faster speed. The effect of IFRS adoption is stronger in countries where there are larger improvements in accounting comparability and for firms with a larger increase in foreign ownership. Overall, our results suggest that accounting standards harmonization facilitates financial market integration.
