Análisis de los factores determinantes de la lealtad hacia los servicios bancarios online
2011
ResumenEl rápido crecimiento de la banca online refleja las ventajas que ésta ofrece respecto a las sucursales convencionales. No obstante, son muchos los consumidores que todavía utilizan los servicios bancarios online de forma esporádica, fundamentalmente para la comprobación de saldos, evitando realizar transacciones con un mayor nivel de riesgo. El objetivo de este estudio es analizar los factores determinantes de la lealtad hacia los servicios bancarios online, a través de un modelo integrador de la influencia del riesgo percibido y la confianza en las webs bancarias con el marco conceptual de la Teoría del Comportamiento Planificado (TCP). La configuración del riesgo percibido se ha p…
It’s a matter of confidence. Institutions, government stability and economic outcomes
2021
In this paper we analyse the effect of constitutional structures over policy outcomes. In particular, we exploit the heterogeneity in parliamentary systems deriving from the presence and the use of the confidence vote to investigate whether stable and unstable parliamentary systems behave differently in terms of the policies they implement. This finer partition of parliamentary systems allows us to identify effects that are more robust than the ones previously discussed in the literature. We show that the difference between presidential and parliamentary systems documented in previous works is driven by a difference between presidential and stable parliamentary systems. We suggest that poss…
Farsighted R&D networks
2014
We analyze the formation of bilateral R&D collaborations in an oligopoly when each firm benefits from the research done by other firms it is connected to. In contrast to myopic stability, farsighted stability leads to R&D networks consisting of two minimally connected components, with the largest one comprising three-quarters of firms.
Conservation Laws and Asymptotic Behavior of a Model of Social Dynamics
2008
Abstract A conservative social dynamics model is developed within a discrete kinetic framework for active particles, which has been proposed in [M.L. Bertotti, L. Delitala, From discrete kinetic and stochastic game theory to modelling complex systems in applied sciences, Math. Mod. Meth. Appl. Sci. 14 (2004) 1061–1084]. The model concerns a society in which individuals, distinguished by a scalar variable (the activity) which expresses their social state, undergo competitive and/or cooperative interactions. The evolution of the discrete probability distribution over the social state is described by a system of nonlinear ordinary differential equations. The asymptotic trend of their solutions…
Evaluating the protecting effects of two consolidants applied on Pietra di Lecce limestone: A neutronographic study
2020
Abstract In this work a combined laboratory-based and neutronographic investigation was carried out on a type of limestone, known as Pietra di Lecce stone, widely used in Italian Baroque as construction material. The limestone was treated with two different commercially-available coatings, namely nanosilica and nanolime, and artificially weathered by salt crystallization and temperature/relative humidity jumps. The aim was to provide an experimental evidence of the protective and consolidating effectiveness of the two treatments by looking at the water absorption process occurring inside the pore network of the analyzed stones. The analysis of the wetting front position revealed significant…
The Effects of Auditor Affinity for Client and Perceived Client Pressure on Auditor Proposed Adjustments
2017
ABSTRACT This paper examines how auditors' judgments about accounting policies may differ when experiencing different levels of affinity for client management and facing different levels of pressure from client management. The theory of motivated reasoning is employed to analyze the effects of these two factors that should lead individual auditors to adopt as a directional goal the acceptance of client management's aggressive accounting. Accordingly, we predict and find that auditors experiencing greater client affinity and facing explicit client pressure suggest lower adjustments to clients' aggressive accounting, consistent with motivated reasoning's goal-related predictions. But our stud…
Availability and consumption of alcoholic beverages: evidence from Finland
2009
The study examines the consumption of alcoholic beverages in Finland over the period 1960 to 2004. Consumption is explained by its own real price, relative prices, expenditure and variables measuring the availability of alcohol. The empirical analysis utilizes information on linkages across different beverages and uses co-integration techniques. The study finds that changes in the availability of alcohol, typically related to institutional changes, have played an important role in determining consumption, especially of beer.
Sensitivity analysis of consumption cycles
2018
We study the special case of a nonlinear stochastic consumption model taking the form of a 2-dimensional, non-invertible map with an additive stochastic component. Applying the concept of the stochastic sensitivity function and the related technique of confidence domains, we establish the conditions under which the system's complex consumption attractor is likely to become observable. It is shown that the level of noise intensities beyond which the complex consumption attractor is likely to be observed depends on the weight given to past consumption in an individual's preference adjustment.
Banking Competition, Housing Prices and Macroeconomic Stability
2012
We develop a dynamic general equilibrium model with an imperfectly competitive bank-loans market and collateral constraints that tie investors credit capacity to the value of their real estate holdings. Banks set optimal lending rates taking into account the effects of their price policies on their market share and on the volume of funds demanded by each customer. Lending margins have a significant effect on aggregate variables. Over the long run, fostering banking competition increases total consumption and output by triggering a reallocation of available collateral towards investors. However, as regards the short-run dynamics, we find that most macroeconomic variables are more responsive …
The Impact of Trade Liberalisation on Water Use: A Computable General Equilibrium Analysis
2008
Water is scarce in many countries. One instrument to improve the allocation of a scarce resource is (efficient) pricing or taxation. However, water is implicitly traded on international markets, particularly through food and textiles, so that impacts of water taxes cannot be studied in isolation, but require an analysis of international trade implications. We include water as a production factor in a multi-region, multi-sector computable general equilibrium model (GTAP), to assess a series of water tax policies. We find that water taxes reduce water use, and lead to shifts in production, consumption, and international trade patterns. Countries that do not levy water taxes are nonetheless af…
