Enterprises are increasingly required to improve their environmental performances. The adoption of environmental innovations (EIs) is believed a way to achieve this goal. So a flourishing debate about the determinants supporting investment in EIs arose. Researchers have thus far paid attention mainly to established manufacturing firms operating in traditional sectors. Hence, scientific literature recommends deepening the behavior of small- and medium-sized enterprises (SMEs) because of the role they play in the productive systems in many Western countries. With this in mind, this study investigates a probabilistic sample of 222 innovative SMEs using the partial least squares and importance–performance map analysis in order to identify the factors affecting their propensity to invest in EIs. Findings show that the propensity results are affected by the firms' environmental awareness, company staff, and capabilities, among the internal factors, whereas among the external ones, the propensity is affected by norms and regulations. An important role is also played by the hope to improve their economic and environmental performances. Monetary and fiscal incentives reveal not to be significant. Consequently, policies should firstly propose an appropriate mix of regulations and stimuli following two directions: a compliance direction to more stringent regulations and rules to be followed through the imposition of penalties and a cultural direction aiming at improving environmental awareness of SMEs about the desirability of pursuing EIs for both ethical and economic reasons, given the potential benefits associated with such innovations. 相似文献

In this paper, we present a mixed oligopoly model where electric power generators compete in supply functions in a liberalized market. A former monopolist, the state‐owned generator, is assumed to be (partially) privatized. First, we obtain that there is a relationship between privatization and the number of electric power generators concerning the level of consumer surplus and total welfare. Indeed, a fully state‐owned generator is socially optimal, lowering private generators' profits and enhancing consumer surplus; that is, if the degree of privatization decreases, consumer surplus increases compensating the damage imposed on generators' profits. Second, as the number of generators increases, full privatization may provide similar levels of consumer surplus and social welfare than those observed in a mixed oligopoly. Moreover, it is also obtained that price‐cost margins increase as marginal cost increases. Overall, our results suggest that the state‐owned generator should be privatized when entry barriers are low enough, and competitiveness is enhanced. Otherwise, a state‐owned generator may protect consumers, enhancing consumer surplus. 相似文献

An upper bound used in consolidating input-output models is shown to be non-minimal, and thus non-optimal. The least upper bound is then obtained. Non-least upper bounds are shown to be useful only when complemented by corresponding lower ones. 相似文献

This study analyzes the impact of economic, financial, and political instability on the liquidity transformation of banks operating in unstable environments. Our main goal is to assess the relationship between overall risk in a country and liquidity transformation. With this goal in mind, we use a sample of five Middle Eastern countries during the period 2005–2010. Our results showed that the high-risk environment has a significant and negative impact on both liquidity transformation and the extension of credit. In addition, we conclude that high capital requirements may reduce further lending, while imposing liquidity requirements seems to be a better strategy for enhancing liquidity transformation. 相似文献

This article proposes a bivariate lattice model for evaluating equity-linked policies embedding a surrender option when the underlying equity dynamics is described by a geometric Brownian motion with stochastic interest rate. The main advantage of the model stays in that the original processes for the reference fund and the interest rate are directly discretized by means of lattice approximations, without resorting to any additional transformation. Then, the arising lattices are combined in order to establish a bivariate tree where equity-linked policy premiums are computed by discounting the policy payoff over the lattice branches, and allowing early exercise at each premium payment date to model the surrender decision. 相似文献
