For‐profit certifier's eco‐labelling is common in industries where firms have some “countervailing power” on sharing gains from labelling. We show that the certification standard for an environmental quality is lowered when firms have strong “power.” A certifier with too low bargaining power will prefer to sell to the best offer rather than bargain. This switch in the selling mechanism also thwarts his incentives in setting the standard. This is consequential for evaluating policies. The dimensions and even signs of welfare changes induced by taxes and subsidies depend upon the mechanism used, and ultimately upon firms’ countervailing power.  相似文献

Abstract

Participation in risky leisure activities (including so‐called ‘extreme’ sports) has increased in recent years, along with a concomitant growth in the related supporting industries, and in media coverage of events and associated lifestyles. The rise in popularity of dangerous leisure pursuits has led to questions about whether these activities should be regulated, or whether legislation should be enacted to prohibit particular activities. Arguments have centred on harm to individuals, and on the potential costs to others, such as families, rescue workers, and society at large. Very little work has been done on the moral legitimacy of dangerous leisure pursuits, and this paper attempts to address this, using a multidisciplinary approach. The paper evaluates both paternalistic and libertarian approaches, and pursues solutions to the moral problem from both utilitarian (consequence‐based) and deontological (duty‐based) perspectives. It is concluded that mature, rational individuals ought to retain the right to pursue activities that have potential deleterious consequences for themselves. While recognising that individuals ought to concern themselves with the effects of their actions on others, the paper accepts arguments based on autonomy, and defends the right to engage in dangerous leisure activities.  相似文献

Abstract

This article designs and prices a new type of participating life insurance contract. Participating contracts are popular in the United States and European countries. They present many different covenants and depend on national regulations. In the present article we design a new type of participating contract very similar to the one considered in other studies, but with the guaranteed rate matching the return of a government bond. We prove that this new type of contract can be valued in closed form when interest rates are stochastic and when the company can default.  相似文献

Contemporary and future low-carbon energy supply requires using the deep underground. Ample evidence shows that onshore oil and gas extraction, associated wastewater injection, deep geothermal systems, and carbon capture and storage can induce damaging seismicity. While induced seismicity exhibits symptoms of a potentially controversial issue, research today has been limited to seismic hazard and risk. Here we argue for the need of social scientific insights to inform risk communication and processes of managing geoenergy-induced seismicity with society.  相似文献

We consider the pricing of European-style structured credit pay-off under the Gaussian Copula Model (GCM). When no sudden jump-to-default events occur, the perfect replication of these pay-offs under the GCM is obtained if and only if the underlying single-name credit spreads follow a particular family of dynamics and if the pricing parameters are given by so-called ‘break-even’ correlations. We exhibit a class of Merton-style models that are consistent with this result. We calculate break-even correlations explicitly to price nth-to-default baskets under the GCM. Finally, we illustrate the usefulness of this concept as a relative-value tool.  相似文献

This paper estimates the effect of the decision to import intermediate goods and capital equipment on Total Factor Productivity (TFP) at the firm level on a panel of Spanish firms (1991–2002). We use two alternative approaches. In the first, we estimate TFP and apply a diff‐in‐diff estimator with a control group constructed by propensity‐score matching. In the second, direct method, we estimate TFP with imported inputs as a state variable in one stage. Both approaches show that the effect of a firm's decision to source intermediates and capital equipment abroad on its TFP depends critically on its capacity to absorb technology, measured by the proportion of skilled labour.  相似文献

In this paper we show that, in the presence of buyer and seller power, a monopolist can enter into a costly contractual relationship with a low-quality supplier with the sole intention of improving its bargaining position relative to a high-quality supplier, without ever selling the good produced by that firm.  相似文献

In the information technology (IT) industry, which confronted a major transition phase during the 1990s, partnerships became a strategic component of the new ‘divided technical leadership’ that emerged from the industry's vertical disintegration. This paper attempts to evaluate the impact of 1676 partnerships on the financial performance (revenue and profit) of 14 large firms and 725 of their partners. On average, there is a positive impact of collaborative agreements on large incumbents and their partners' financial performance. These results vary according to the type, form and content of the agreement and according to the partner's field of activity. Incumbents get the most benefit from broad informal alliances while smaller and more hierarchical forms of partnerships (consortia, joint-ventures) do profit to their partners. For large incumbents, partnerships are more effective with partners from the services industry than with partners from the IT industry.  相似文献

Abstract

Harrod's contribution to economic dynamics is very often reduced to the dynamic equation whose character is unstable. Growth theory and cycle theory based on Harrod's contributions aimed at reducing this instability. Following Harrod, who was strongly opposed to the ‘knife-edge’ interpretation, we define the warranted rate of growth as a ‘moving equilibrium’ and focus on its interaction with the effective rate of growth. Our simple Harrodian model generates various dynamics from stable path, to growth cycle and corridor of stability.  相似文献

In recent years, a growing literature has claimed that the market microstructure is sufficient to generate the so-called stylized facts without any reference to the behaviour of market players. Indeed, qualitative stylized-facts can be generated with zero-intelligence traders (ZITs) but we stress that they are without any quantitative predictive power. In this paper we show that in most of the cases, such qualitative stylized facts hide unrealistic price motions at the intraday level and ill-calibrated return processes as well. To generate realistic price motions and return series with adequate quantitative values is out-of-reach using pure ZIT populations. To do so, one must increasingly constrain agents?? choices to a point where it is hard to claim that their behaviour is completely random. In addition we show that even with highly constrained ZIT agents, one cannot reproduce real time series from these. Except in a few cases, first order moments of ZITs never equal real data ones. We therefore claim that stylized facts produced by means of ZIT agents are useless for financial engineering.  相似文献
