Accelerators: an assessment of acceleration models

Accelerators assist early-stage ventures by offering networking opportunities, access to funding and training. We map business accelerators in five categories: Independent Accelerators (IA), Corporate Accelerators (CA), Hybrid Accelerators (HA), University Accelerators (UA), and Government Accelerators (GA). We argue that accelerators can be described by two main acceleration models…

Our study reveals the existence of four pure types of angel investor identities and suggests how these identities shape their investment behavior and consequent exchange of resources with investees. We summarize our results in a…

No maintenance activity can be performed without understanding at least the part of the program that needs to b emodified. Therefore, considering its cost, helping developers to understand programs is a must. Consequently, our research aims at building a business related model of the program semantics, which is grounded in Perkinsfi research in psychology. After a short reminder of…

Is taxing waste a waste of time?: evidence from a Supreme Court decision

Environmental taxes are often underexploited. This paper analyses the effectiveness of a garbage tax, assessing its effects on multiple outcomes as well as its acceptability. We study how a Supreme Court decision, mandating the Swiss Canton of Vaud to implement a tax on garbage, affects garbage production and beliefs about the tax. We adopt a difference-in-differences approach…

Le sentiment d'appartenance au Grand Genève demeure problématique: analyse des articles de presse et des discours politiques (2005-2017)

Le projet "Grand Genève" peine à créer autour de lui un sentiment d'identification fort. La collaboration entre le canton de Genève, le canton de Vaud et les départements de la Haute-Savoie et de l'Ain reste depuis 2005 une entreprise qui apparaît lointaine et détachée de toute notion affective aux yeux de la population. L'étude des discours politiques et des…

Operational route choice methodologies for practical applications

This paper focuses on the application of tractable route choice models and presents a set of methods for deriving relevant disaggregate and aggregate route choice indicators, namely link and route flows. Tractability is achieved at the disaggregate level by the recursive logit model and at the aggregate level by the mental representation item (MRI) approach. These two approaches are…

Train timetable design under elastic passenger demand

A passenger centric timetable is such a timetable that the satisfaction of the passengers is maximized. However, these timetables only maximize the probability of a passenger to take the train, but provide no insight on the actual choices of the passengers. Therefore, in this manuscript we replace the deterministic passenger satisfaction function with a probabilistic demand…

The feasibility of equilibria in large ecosystems: a primary but neglected concept in the complexity-stability debate

The consensus that complexity begets stability in ecosystems was challenged in the seventies, a result recently extended to ecologically-inspired networks. The approaches assume the existence of a feasible equilibrium, i.e. with positive abundances. However, this key assumption has not been tested. We provide analytical results complemented by simulations which show that equilibrium…

Modeling purchases of new cars: an analysis of the 2014 French market

This paper analyzes and compares different policy scenarios as well as discusses price elasticities and willingness to pay and to accept using revealed preference (RP) data from the French new-car market in 2014 by means of a cross-nested logit (CNL) model. We focus particularly on electric and hybrid vehicles. We use interactions between the cost (both fixed and running costs) and…

The impact of HR practices on employee normative, affective and continuance commitment

A quantitative survey with 164 employees of a town hall in Switzerland reveals that only 35 HR practices out of 150 are linked to employee commitment. HR practices are more linked to normative commitment than to affective or continuance commitment. Normative commitment depends on employees’ job and work relations, and to indirect compensation. Affective commitment also depends on the…
