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

The paper analyses the characteristics of the supply of higher education in different geographical macroareas using a strategic interaction framework. It focuses on universities operating in centralised funding system that autonomously set the quality of education showing that in equilibrium it is inversely related to students’ moving costs across areas. We show that in the presence of asymmetric information about workers’ ability and asymmetric costs of moving, the only PBE consistent with forward induction involves that only high ability workers acquire education and the quality of education is lower in macroareas where the moving costs are higher. Our model predicts that in economies with centralised university funding, educational policies must be regulated according to the specific socioeconomic characteristics of the area. Direct subsidies to universities may be ineffective in improving the quality of education in the less developed areas. When regional disparities are not too big, efficiency gains may be obtained by reducing moving costs. 相似文献

Model averaging has become a popular method of estimation, following increasing evidence that model selection and estimation should be treated as one joint procedure. Weighted‐average least squares (WALS) is a recent model‐average approach, which takes an intermediate position between frequentist and Bayesian methods, allows a credible treatment of ignorance, and is extremely fast to compute. We review the theory of WALS and discuss extensions and applications. 相似文献

This paper presents a principal-agent model in which the agent has imprecise beliefs. We model this situation formally by assuming the agent?s preferences are incomplete as in Bewley (1986) [2]. In this setting, incentives must be robust to Knightian uncertainty. We study the implications of robustness for the form of the resulting optimal contracts. We give conditions under which there is a unique optimal contract, and show that it must have a simple flat payment plus bonus structure. That is, output levels are divided into two sets, and the optimal contract pays the same wage for all output levels in each set. We derive this result for the case in which the agent?s utility function is linear and then show it also holds if this utility function has some limited curvature. 相似文献

Aggregate investment in the US economy displays a hump-shaped pattern in response to shocks, and the autocorrelation of aggregate investment growth is positive for the first few quarters, turning negative for the later quarters. This paper shows that this feature of the data is the natural outcome of a two-sector consumption/investment model designed and calibrated to reproduce plant-level evidence on capital accumulation. 相似文献

Models used in neoclassical economics assume human behavior to be purely rational. On the other hand, models adopted in social and behavioral psychology are founded on the “black box” of human cognition. In view of these observations, this paper aims at bridging this gap by introducing psychological constructs in the well‐established microeconomic framework of choice behavior based on random utility theory. In particular, it combines constructs developed employing Ajzen's theory of planned behavior with Lancaster's theory of consumer demand for product characteristics to explain stated preferences over certified animal‐friendly foods (AFF). To reach this objective, a Web survey was administered in the largest five EU‐25 countries: France, Germany, Italy, Spain, and the United Kingdom. Findings identify some salient cross‐cultural differences between northern and southern Europe and suggest that psychological constructs developed using the Ajzen model are useful in explaining heterogeneity of preferences. Implications for policymakers and marketers involved with certified AFF are discussed. 相似文献

Ratios of public debt to GDP are much discussed these days and questions concerning debt relative to taxation have long been explored by fiscal scholars. With respect to monarchical regimes, it seems reasonable to treat public debt as similar to personal debt, recognizing that a monarch is not an ordinary person. When public debt arises through parliamentary assemblies, however, the similarity of form between public and personal debt vanishes because a parliamentary assembly does not trade on its own account; to the contrary, it is a type of intermediary that brings together people who buy bonds and people who later pay the bondholders. In a republic there is no sovereign who is indebted to ruled subjects. The institutional framework of republican governance transforms public borrowing into a process of intermediation among citizens, which leads in turn to the alternative orientation toward public debt that this paper explores. 相似文献
