Perceptions of assortment variety: The effects of congruency between consumers’ internal and retailers’ external organization

This research shows that consumers’ perceptions of variety and satisfaction are dependent upon how the assortment is organized, both internally by the consumer and externally by the retailer. The results of three laboratory studies indicate that for familiar categories, congruency between a consumer's internal categorization structure and the external store layout leads to higher perceptions of variety and higher satisfaction with product choices, while for unfamiliar product categories, congruency between shopping goals and external structure leads to lower perceptions of variety but increased satisfaction with the store's assortment. However, if retailers institute external category filters congruent with consumers’ internal shopping goals that allow them to bypass products, consumers have both lower variety perceptions and satisfaction with the assortment offering.     

Team formation with complementary skills

One explanation for the prevalence of self‐managed work teams is that they enable workers with complementary skills to specialize in the tasks they do best, a benefit that may be enhanced if workers can sort themselves into teams. To assess this explanation, we design a real‐effort experiment to study the endogenous formation of teams, and its effect on productivity, when specialization either is or is not feasible. We find a strong positive interaction between endogenous team formation and the ability to specialize, indicating that endogenous team formation is a particularly effective mechanism for promoting team output in production environments that enable the exploitation of skill complementarities.

A bootstrap analysis to investigate the economic efficiency of the logistics industry in Italy*

As argued by literature and consultancy reports, logistics enhances both productivity and competitiveness of several manufacturing supply chains. The analysis of the efficiency trends of logistics providers may shed light on some relevant aspects that can impact on the competitiveness of national industrial systems. Thus, the paper focuses on the Italian logistics supply, shedding lights on the distribution of the efficiency level within the logistics sector and its causes. The analysis is based on a two-stage methodology aimed at estimating the Italian logistics firms’ efficiency and defining some characteristics impacting the efficiency level. At first, we implement a Data Envelopment Analysis model based on balance sheet data, for the period 2006–2012, then an econometric regression is performed in order to identify the effects of main companies’ characteristics on firms’ efficiency. According to our results, size and geographical location are two of the most impacting variables explaining the efficiency score of the Italian logistics providers.     

Neutral carbon tax and environmental targets in Brazil

We evaluate the effects of a carbon tax in the Brazilian economy using an input–output framework. First, we consider the impacts of a carbon tax of US$ 10 and US$ 50/metric ton of CO₂ equivalent. As usual, the adoption of the carbon tax generates adverse effects on GDP, wages and jobs in the short term, but reduces emissions and generates new government revenues, especially in the case of the greater tax. Second, we consider a broader tax system reform. In this reform, we replace distortionary taxes by a tax on value added. To compensate for the loss of government revenue, we assume a carbon tax with equivalent revenue. We find that the net effect is a GDP increase of 0.47%, the creation of 533 thousand jobs and reduction of 1.6 million tons of CO₂ emissions. Both scenarios exempt exports and levy imports to correct adverse effects on the country’s competitiveness.     

Combining homogeneous groups of preclassified observations with application to international trade

This article proposes three methods for merging homogeneous clusters of observations that are grouped according to a pre‐existing (known) classification. This clusterwise regression problem is at the very least compelling in analyzing international trade data, where transaction prices can be grouped according to the corresponding origin–destination combination. A proper merging of these prices could simplify the analysis of the market without affecting the representativeness of the data and highlight commercial anomalies that may hide frauds. The three algorithms proposed are based on an iterative application of the F‐test and have the advantage of being extremely flexible, as they do not require to predetermine the number of final clusters, and their output depends only on a tuning parameter. Monte Carlo results show very good performances of all the procedures, whereas the application to a couple of empirical data sets proves the practical utility of the methods proposed for reducing the dimension of the market and isolating suspicious commercial behaviors.     

A case study for a new metrics for economic complexity: The Netherlands

We present a new approach for the economic analysis of countries, which we apply to the case of the Netherlands. Our study is based on a novel way to quantify exported products’ complexity and countries’ fitness which has been recently introduced in the literature. Adopting a framework in which products are clustered in sectors, we compare the different branches of the export of the Netherlands, taking into account the time evolution of their volumes, complexities and competitivenesses in the years 1995–2010. The High Tech and Life Sciences sectors share high quality products but low competitiveness; the opposite is true for Horticulture and Energy. We analyze in detail the Chemicals sector, finding a declining global complexity which is mostly driven by a shift towards products of lower quality. A growth forecast is also provided. In light of our results we suggest a differentiation in policy between the country’s self-defined industrial sectors.     

Have Standard VARS Remained Stable Since the Crisis?

Small vector autoregressions are commonly used in macroeconomics for forecasting and evaluating shock transmission. This requires VAR parameters to be stable over the evaluation and forecast sample or modeled as time‐varying. Prior work has considered whether there were sizable parameter changes in the early 1980s and in the subsequent period until the beginning of the new century. This paper conducts a similar analysis focused on the period since the recent crisis. Using a range of techniques, we provide substantial evidence against parameter stability. The evolution of the unemployment rate seems particularly different relative to its past behavior. We also evaluate alternative methods to handle parameter instability in a forecasting context.

Setting Strategies outside a Typical Environmental Perspective Using ISO 14001 Certification

The scope of this research is to evaluate whether ISO 14001 certification could be used as a strategic vehicle for achieving objectives that are not strictly linked to a technical and operative perspective, and to determine what these objectives are. In order to find these objectives, a review of the literature was first conducted to determine what they were and seven hypotheses emerged. The hypotheses concerned the possibility of using ISO 14001 as a strategy for achieving objectives related to finance and turnover, customer satisfaction, community satisfaction, employee satisfaction, health and safety in the workplace, and growth and skills of employees. The validity of each hypothesis was tested via a survey of 164 managers of European manufacturing companies. This research produced interesting findings, some of which contradicted the findings of other research, in particular for financial and turnover objectives. In addition, the research revealed interesting relationships between employees' skills and issues such as Design for the Environment and Sustainability. Furthermore, some limitations of ISO 14001 with respect to the Eco‐Management and Audit Scheme regulation emerged. Copyright © 2017 John Wiley & Sons, Ltd and ERP Environment
