Efectos de las consultas boca a boca en redes sociales en la compra de cosméticos en Ecuador.
2022
Las redes sociales han reestructurado el paradigma de la comunicación en el marketing. Investigaciones recientes demuestran que la conducta de consultar reseñas está adquiriendo un rol fundamental en la decisión de compra de los consumidores. En este contexto, el presente estudio desarrolló un marco de investigación para determinar la cadena de relación entre influencia social, credibilidad percibida del boca a boca, adopción del boca a boca e intención de compra aplicada a la industria cosmética del Ecuador. A través de una muestra de 406 consumidores y la aplicación del método de análisis de ecuaciones estructurales, los resultados evidencian el vínculo existente entre las variables plant…
An adaptation-mitigation game: does adaptation promote participation in international environmental agreements?
2022
AbstractThis paper studies how the investment in adaptation can influence the participation in an international environmental agreement (IEA) when countries decide in adaptation before they choose emissions. Three types of agreements are studied, a mitigation agreement for which countries coordinate their decisions only on emissions; an adaptation agreement for which there is only coordination when countries decide their levels of adaptation and a complete agreement when there is coordination in both emissions and adaptation levels. In every case, we assume that the degree of effectiveness of adaptation is bounded from above, in order words, adaptation can alleviate the environmental proble…
Self-enforcing international environmental agreements revisited
2004
In Barrett's (1994) paper on transboundary pollution abatement is shown that if the signatories of an international environmental agreement act in a Stackelberg fashion, then, depending on parameter values, a self-enforcing IEA can have any number of signatories between two and the grand coalition. Barrett obtains this result using numerical simulations and also ignoring the fact that emissions must be non-negative. Recent attempts to use analytical approaches and to explicitly recognize the non-negativity constraints have suggested that the number of signatories of a stable IEA may be very small. The way such papers have dealt with non-negativity constraints is to restrict parameter values…
Appropriate technology in a Solovian nonlinear growth model
2007
We propose a Solovian growth model with a convex-concave production function and international technological spillovers. We test the empirical implications of the model, analysing the effects of the productivity slowdown that followed the oil shocks of the 1970s. We argue that this slowdown, altering the world income distribution, affected the pattern of international technological spillovers, taking the poorest countries further away from the technological leaders, and therefore unable to exploit their technologies. The result is the emergence of a poverty trap for low-income countries.
Adopting sustainable irrigation technologies in Italy: a study on the determinants of inter- and intra-farm diffusion
2023
This paper analyses the drivers for adopting irrigation systems with water conservation and saving technologies (WCSTs) by Italian farmers. The agricultural sector in Italy, like in other Mediterranean countries, suffers from water scarcity and water endowment variability. Water resources play a decisive role in agricultural production and in implementing large-scale WCSTs capable of improving the resilience of the whole agricultural sector. This study uses a microeconomic panel data approach to estimate farmers' decisions in adopting (inter-farm) sustainable irrigation technologies and assesses the intensity of (intra-farm) water-saving practices. Our analysis identifies the main determina…
''Dual'' gravity: Using spatial econometrics to control for multilateral resistance.
2007
We propose a quantity-based `dual' version of the gravity equation that yields an estimating equation with both cross-sectional interdependence and spatially lagged error terms. Such an equation can be concisely estimated using spatial econometric techniques. We illustrate this methodology by applying it to the Canada-U.S. data set used previously, among others, by Anderson and van Wincoop (2003) and Feenstra (2002, 2004). Our key result is to show that controlling directly for spatial interdependence across trade flows, as suggested by theory, significantly reduces border effects because it captures `multilateral resistance'. Using a spatial autoregressive moving average specification, we …
Growth and convergence in Africa: The impact of spatial effects
2010
The aim of this paper is to study the impact of spatial effects on convergence process in Africa over the period 1975-2000. Taking into account these effects through the methodology of Exploratory Spatial Data Analysis (ESDA) and spatial econometrics, we focus on the geographical dimension of economic convergence of African countries. This allows us to deal with spatial autocorrelation which is a consequence of econometric interdependences due to geographic spillovers. Indeed, countries economic performance hides specific geographical patterns providing information on the importance of location on economic dynamics. Our results prove the existence of convergence process in Africa through a …
Networks of knowledge among unionized firms
2008
We develop a model of strategic networks in order to analyze how trade unions will affect the stability of R&D networks through which knowledge is transmitted in an oligopolistic industry. Whenever firms settle wages, the partially connected network is likely to emerge in the long run if and only if knowledge spillovers are large enough. However, when unions settle wages, the complete network is the unique stable network. In other words, the stronger the union bargaining power is, the more symmetric stable R&D networks will be. In terms of network efficiency, the partially connected network (when firms settle wages) does not Pareto dominate the complete network (when unions settle wages) an…
Networks of manufacturers and retailers
2011
We study the endogenous formation of networks between manufacturers of differentiated goods and multi-product retailers who interact in a successive duopoly. Joint consent is needed to establish and/or maintain a costly link between a manufacturer and a retailer. We find that only three distribution networks are stable for particular values of the degree of product differentiation and link costs: (i) the non-exclusive distribution & non-exclusive dealing network in which both retailers distribute both products is stable for intermediate degree of product differentiation and small link costs; (ii) the exclusive distribution & exclusive dealing network in which each retailer distributes a dif…
A strategic approach for the discounted Shapley values
2014
The family of discounted Shapley values is analyzed for cooperative games in coalitional form. We consider the bargaining protocol of the alternating random proposer introduced in Hart and Mas-Colell (Econometrica 64:357–380, 1996). We demonstrate that the discounted Shapley values arise as the expected payoffs associated with the bargaining equilibria when a time discount factor is considered. In a second model, we replace the time cost with the probability that the game ends without agreements. This model also implements these values in transferable utility games, moreover, the model implements the \(\alpha \)-consistent values in the nontransferable utility setting.
