The impact of scale effects on the prevailing internet-based banking model in the US

2011

Internet-based banks use a technology-intensive production process that may benefit from scale effects as they grow larger. This article analyzes whether the predominant Internet-primary bank in the USA generates technology-based economies of scale in the period 2002–2010. There is evidence of both favorable and adverse technology-based scale effects. As the leading Internet-primary bank gets larger, the financial performance gap with traditional banks shrinks while some of its critical competitive advantages wear down. The results suggest that unless the prevailing Internet-primary bank preserves the distinctive advantages of the Internet-based business model as it improves financial perfo…

Zaangażowane badania jakościowe – perspektywa autobiograficzna

2018

The presented article is an attempt to reconstruct/retrospect my professional biography in its methodological section. It is a description of the way I went to become a biographic, narrative scholar. It is also a description of the reasons – theories, concepts, discussions and disputes that accompanied me on the way. I present my critical attitude towards Polish school and Polish education, posing questions about education, school and teacher. The second matter that organizes my research is the question about interpersonal relationships, intimacy, marriage, family and what is happening between: spouses, partners, parents and children. I ask what in our relationships with others favours a ha…

The nature of quantities influences the representation of arithmetic problems: evidence from drawings and solving procedures in children and adults

2017

International audience; When solving arithmetic problems, semantic factors influence the representations built (Gamo, Sander & Richard, 2010). In order to specify such interpretative processes, we created structurally isomorphic word problems that could be solved with two distinct algorithms. We tested whether a distinction between cardinal and ordinal quantities would lead solvers, due to their daily-life knowledge, to build different representations, influencing their strategies as well as the nature of their drawings. We compared 5th grade children and adults in order to assess the validity of this hypothesis with participants of varying arithmetic proficiency. The results confirmed that…

On the Bullwhip Avoidance Phase: supply chain collaboration and order smoothing

2009

This paper provides an assessment of the impact of collaboration and smoothing replenishment rules on supply chain operational performance and customer service level. Three supply chain configurations (i.e. Traditional, Information Exchange and Synchronised) in which orders are generated by smoothing (S, R) inventory control policies are studied for different proportional controllers. A supply chain stress test is performed through a sudden and intense change in demand. A structured and extended supply chain assessment framework is adopted. The main conclusions of this paper are the following. (i) The impact of Supply Chain Collaboration on overall supply chain performance is greater than t…

Inventory policies and information sharing in multi-echelon supply chains

2011

The aim of this article is to show how to modify a replenishment rule in relation to the operational information shared by suppliers. More specifically, we present a model of an Automatic Pipeline Variable Inventory and Order-Based Production Control System rule for a multi-echelon supply chain characterised by different increasing levels of shared information. A numerical study is presented to underline the performance differences for three variants of the smoothing order rule in terms of bullwhip reduction, inventory stability and operational and customer responsiveness. Results show how the effectiveness of a smoothing replenishment rule depends on the level of information sharing.

Formulations for an inventory routing problem

2014

In this paper, we present and compare formulations for the inventory routing problem (IRP) where the demand of customers has to be served, over a discrete time horizon, by capacitated vehicles starting and ending their routes at a depot. The objective of the IRP is the minimization of the sum of inventory and transportation costs. The formulations include known and new mathematical programming formulations. Valid inequalities are also presented. The formulations are tested on a large set of benchmark instances. One of the most significant conclusions is that the formulations that use vehicle-indexed variables are superior to the more compact, aggregate formulations.

Determinants of Individual Investment Decisions in Investment-Based Crowdfunding

2017

We investigate determinants of investment decisions in investment-based (equity and real estate) crowdfunding, using a novel investment-, investor- and campaign-level database. We find that this market is a man's world, with nearly 93% of investments made by men. Consistent with behavioral and finance theories, we find that women invest less in the riskiest investments but more in safer ones. Further analyses show that these findings are better explained by differences in risk aversion than differences in overconfidence between men and women. Investors located in an area considered more "sociable" (socially friendly) also invest more, but only if the investor is a woman. Overall, the findin…

Circular Economy and Value Creation: Sustainable Finance with a Real Options Approach

2021

This paper presents a methodological proposal that integrates the circular economy concept and financial valuation through real options analysis. The Value Hill model of a circular economy provides a representation of the course followed by the value of an asset. Specifically, after the primary use, the life of an asset may be extended by going through four phases: the 4R phases (Reuse, Refurbish, Remanufacture and Recycle). Financial valuation allows us to quantify value creation from firms’ asset circularity under uncertainty, modelled by binomial trees. Furthermore, the 4R phases are valued as real options by applying no-arbitrage opportunity arguments. The major contribution of this pap…

The evaluation of urban soils aimed at the sustainability of plants in public and private flowerbeds

2020

The authors report the survey of some flowerbeds located in the city of Palermo with the aim of assessing the sustainability of the plants and the interventions to be implemented, i.e. cutting or transfer of plants, to achieve a sustainable green. In the case in which it is possible to insert other plants in the flowerbeds, it is recommended to elaborate a project using programs that allow to have a preview of the spaces available for the new plants. This work is methodological and is aimed at creating a green that can achieve the functional objectives in relation to the site where it is located (sustainability in all aspects) and at low management costs with no or almost no irrigation prac…
