Dramatic natural events recently stroke several countries worldwide. The impact of the natural events on industrial sites often resulted in large releases of hazardous materials, causing severe technological accidents (Natural-Technological or NaTech events). Industrial operators were often found unprepared or off-guard for unannounced events but also when they had received early warnings. Due to these occurrences, public awareness has raised and the issue of NaTech is now considered as an emerging risk. Due to the climate change and increase in the frequency of some categories of natural disasters, the likelihood of NaTech scenarios is growing, thus NaTech may be also considered as a new risk in some areas of the world. In the present study, the process that ended in the awareness of the scientific community and of the general public toward NaTech has been analyzed. Available tools and knowledge gaps in the assessment of NaTech scenarios are evidenced. The analysis is mainly addressed to the potential impact of flood, lightning, and earthquake events on industrial installations where hazardous substances are present, aiming at the identification of strategies to improve the resilience of industrial facilities to technological accidents caused or intensified by natural hazards.  相似文献

This paper estimates the effect of research and investment activities on patents across countries, industries and over time, using Poisson and negative binomial distribution models. The first result of the paper is the recognition of the importance of investment activities in contributing to technical change. The positive role of research expenditures is also confirmed but its elasticity is found to be lower than in previous studies. Important differences across sectors emerge: research expenditures are found to be more effective in generating patents in science based industries, while investment is particularly significant in supplier dominated and production intensive industries. Finally, in most sectors, the estimated R&D and investment coefficients lie outside the confidence intervals calculated around the pooled coefficients.  相似文献

In this paper we argue that when a subgroup of countries cooperate on emission reduction, the optimal response of non-signatory countries reflects the interaction between three potentially opposing factors, the incentive to free-ride on the environmental benefits of cooperation, the incentive to expand energy consumption, and the incentive to adopt the cleaner technologies introduced by the coalition. Using an Integrated Assessment Model with a game-theoretic structure we find that the equilibrium abatement of the coalition composed by OECD countries would be moderate, in line with the Pledges subscribed in Copenhagen, but increasing. The mitigation strategy would consist of investments in energy R&D and deployment of cleaner technologies with high learning potentials. International knowledge and technology externalities would facilitate the diffusion of cleaner technologies in non-signatory countries, offsetting the free-riding incentive and reducing their emissions. If the OECD group curbs emissions beyond the optimal equilibrium level, reaching reduction rates between 40 and 45 % below 2005 levels in 2050, the benefits of technology externalities would no longer compensate the effect of lower fossil fuel prices. Our results suggest that a moderate unilateral climate policy could induce a virtuous behaviour in non-signatory countries and that policies promoting the international transfer of technologies and knowledge could represent an effective complement to mitigation targets.  相似文献

Published research on credit counseling and mortgage termination is surprisingly scarce, despite substantial growth in this industry. While the purpose of counseling is to assist low-income borrowers to improve their handling of debt and thereby reduce default, counseling may also improve the borrowers understanding of their financial position and thus induce optimal mortgage termination. Using a competing-risks framework, we study the effects on default and prepayment of a counseling program implemented in several Midwest states. We find weak evidence of that the default hazard was lower for graduates of the counseling program, but that their default behavior was more optimal. The prepayment hazard was higher for counseled borrowers, but their prepayment behavior was not more optimal. Overall, counseling seems to affect the lenders profits, but the net effect should be evaluated both in terms of prepayment and default.  相似文献

Choice for patients, over varying aspects of healthcare, is becoming an increasingly common feature in Europe, especially in tax-funded healthcare systems. This paper investigates patients’ choice of healthcare provider. The middle class, in countries implementing choice reforms, is shown to have a pronounced preference for the availability of choice as a component of a quality healthcare system. Important implications of this for theory and policy are discussed.  相似文献

The literature has recently asked whether the effects of fiscal policy vary with the state of the economy (Christiano, Eichenbaum, and Rebelo 2011; Rendahl 2014; Auerbach and Gorodnichenko 2012). We study this question in the context of vector autoregression (VAR) estimation. We show formally that, if (asymptotically) the parameters of the reduced-form VAR differ, then the dynamic effects of fiscal policy differ as well, generically and for any set of identification assumptions. Thus, in theory, the econometrician can detect these differences (either across time or space) generically just by relying on reduced-form VAR estimation.  相似文献

The mortgage payoff dilemma affects many retirees that have enough financial assets to pay off their mortgage. I find that, on average, retirees with less than $300,000 in non-housing financial wealth are better off keeping the mortgage and investing.  相似文献

Two experiments designed to investigate how the shape and colour of packaging, and product category, conjointly impact consumers’ product and packaging expectations are reported. In Experiment 1, the shape (rounded vs. angular) and visual appearance (greyscale, red‐to‐yellow and blue‐to‐green colour schemes) of the packaging were manipulated. Dependent measures were preference (willingness to purchase the product, how attention‐capturing the packaging is, and the pleasantness of the design) and any taste associations. In Experiment 2, shape (rounded vs. angular), colour (red‐to‐yellow vs. blue‐to‐green colour schemes), and product category (buttery vs. cereal cookies) were manipulated. In this case, the dependent measures were the perceived product healthiness and the preference of consumers. The results of Experiment 1 revealed that packaging colour influenced product preference. Red‐to‐yellow and blue‐to‐green colour schemes and angular packaging were preferred over greyscale and round packaging. Colour also influenced taste associations, while shape only influenced ratings of expected sweetness. In Experiment 2, packaging shape and product category influenced product preference. In particular, rounded packaging and the packaging of buttery cookies were preferred over angular packaging and the cereal cookies packaging. The healthiness of the product was rated higher for the rounded and red‐to‐yellow packaging containing a buttery product. Taken together, these results highlight the important role played by colour, shape, and category on the expectations and associations elicited by viewing product packaging.  相似文献

While corporate social responsibility (CSR) is recognized as taking on various national meanings and practices, research has not sufficiently investigated how multinational companies (MNC) simultaneously achieve global CSR integration and local CSR adaptation. Building on a qualitative case study carried out at ASICS, an MNC headquartered in Japan, we show how this organizational dilemma may be solved through hybridization work, a form of institutional work performed by CSR managers in subsidiaries to combine and adapt different institutional approaches to CSR. By developing the notion of hybridization work, we contribute by (1) revealing a set of practices that contribute to institutional change within organizations and (2) enriching the study of CSR organizational change and international business by showing how hybridization Work leads to a greater organizational integration between core and periphery, and by identifying the triggering factors for subsidiary initiative in CSR.  相似文献

The specification of an optimizing model of the monetary transmission mechanism requires selecting a policy regime: commonly, commitment or discretion. In this paper we propose a new procedure for testing optimal monetary policy, relying on moment inequalities that nest commitment and discretion as two special cases. The approach is based on the derivation of bounds for inflation that are consistent with optimal policy under either policy regime. We derive testable implications that allow for specification tests and discrimination between the two alternative regimes. The proposed procedure is implemented to examine the conduct of monetary policy in the US economy.  相似文献
