No full textMeasuring motivational patterns: a formal approach of conservation of resources theory
Get PDFThe present research develops a formal mathematical model to measure individual motivation at work. Its mathematical specifications correspond to a formal translation of Conservation of Resources (COR) theory core assumptions. It explores how such COR constructs as resource caravan and resource passageway determine patterns of motivational processes. The model is applied to a sample of working professionals (n= 8) from different occupations. Data is obtained from a 5-item Lickert-scale questionnaire based on the COR-Evaluation (COR-E) instrument developed by Hobfoll et al. (1992). Results are presented in the form of eight different Tables that correspond to eight different resource caravans. They unveil how individual motivational processes vary by the extent to which resources interact with an underlying drive for preservation. The role of context is also confirmed as a resource passageway. With regard to methodology, this research emphasizes how measurement based on mathematical modeling can be an alternative to standard data-analytic statistics. At a theory level, it enriches both COR-based literature and theory of workplace motivation. Practically, it provides an analytical instrument that details information on those processes that shape individual motivational profiles in organizations
Les mutations du formalisme testamentaire, entre évolutions jurisprudentielles et analyse prospective
No full textL’arrêt rendu par l’Assemblée plénière de la Cour de cassation le 17 janvier dernier concernant le testament international illustre l’influence considérable exercée par la jurisprudence sur les principes applicables à la forme des testaments. Cette importante décision a constitué le point de départ d’une réflexion plus large consacrée aux mutations du formalisme testamentaire. Le présent dossier invite, en ce sens, à porter tout à la fois un regard critique sur les procédés prétoriens œuvrant au sauvetage de certains testaments, et un regard prospectif sur ce que pourrait être le formalisme testamentaire au temps du numérique
L’Église hors-la-loi ? Menaces sur la libertas Ecclesiæ
No full textLa liberté de l’Eglise d'annoncer le message évangélique est-elle compromise ? De nombreuses affaires judiciaires ou médiatiques montrent une hostilité sans cesse grandissante à l'encontre de l’Eglise et de sa mission. Ce livre dresse le bilan d'une laïcité bien peu ouverte et de plus en plus agressive, qui menace concrètement la liberté de l'Eglise
Lock-in in Renewable Energy Generation under Constraining Capacities and Heterogenous Conversion Performances
Get PDFThe theme of the ’energy transition’ away from fossil fuels toward clean renewable energy has attracted a lot of attention in the context of climate change mitigation. However the emergence of a new energy system raises its own problems. An aggressive carbon pricing or a renewables subsidisation policy can result in fast investment in poor performing energy conversion capacities. Once installed the industry will remain locked-in in these inferior technical options especially if capital investments are submitted to adjust-ment costs. With the help of a stylized fully dynamic model, we show the following. Without an access cost to primary energy (e.g. solar radiation) the industry can run more performing equipments even if they are both more costly to operate and more costly to build provided a suÿciently strong en-ergy demand. With this preliminary result in hands we assume next convex access costs to primary energy, due for example to limited space access con-straints. The high performing energy conversion technique has now a produc-tivity advantage. However for a small energy demand it can remain optimal for the industry to first deploy high performance equipments together with low performing ones before dismantling their stock of high performing equip-ments. Despite the increase of the marginal access cost to primary energy coming alongside the deployment of production capacities, thus inducing a fall of the cost gap between the two technologies, the capital price of the high performing equipments can fall down to zero before the capital price of low performing ones because of the building costs gap, implying that the industry should scrap in the end its high performing equipments while still investing in low cost (and low performing) ones. This ’transition inside the transition’ problem provides also interesting insights concerning the regulation of the energy transition towards renewable energy. It suggests that avoiding lock-in in renewable energy provision is more a matter of speed of increase of the carbon price than just the fixation of its level at any moment
Do cryptocurrencies matter?
Get PDFIn our dynamic general equilibrium model, agents can invest in money and in a production technology exposed to shocks. If the government is non-benevolent and has a monopoly over money issuance it issues too much money, to finance excessive public expenditures. We study the effects of a cryptocurrency in limited supply but with crash risk. If the crash risk is not too large, competition from the cryptocurrency constrains the government’s monetary policy. If the government is non-benevolent, this constraint improves citizens welfare, but if the government is rather benevolent competition from the cryptocurrency can lower citizens’ welfare
Platform Disintermediation with Repeated Transactions
Get PDFWe consider a setting in which a platform matches buyers and sellers, who then wish to transact with each other multiple times. The platform charges fees for hosting transactions, but also offers convenience benefits. We consider two scenarios. In one scenario, all transactions must occur on the platform; in the other scenario, buyers and sellers can disintermediate the platform after the first transaction, and do subsequent transactions offline. We find that the platform reacts to disintermediation by using a “front-loaded” pricing scheme, whereby it charges more for earlier transactions. We also show that sometimes the platform is better off when disintermediation is possible—because it can use disintermediation to screen users’ private information about their convenience benefits. Buyers are not necessarily better off when they can disintermediate, due to the way in which the platform adjusts its fees
