Using experimental data of children and their mothers, this paper explores the intergenerational relationship of impatience. The child’s impatience stems from a delay of gratification experiment, the mother’s from a choice task. Findings demonstrate an intergenerational relationship in decision making. 相似文献

In this paper, I compare two-part tariff competition to linear pricing in a vertically differentiated duopoly. Consumers have
identical tastes for quality but differ in their preferences for quantity. The main finding is that quality differentiation
occurs in equilibrium if and only if two-part tariffs are feasible. Furthermore, two-part tariff competition encourages entry,
which in turn increases welfare. Nevertheless, two-part tariff competition decreases consumer surplus compared to linear pricing. 相似文献

We analyse the short- to mid-run effects of spatial relocation strategies on firm innovativeness and productivity growth. Using conditional difference-in-difference estimation with multiple treatments, we find for a sample of German firms in 1999–2013 that offshoring has a statistically significant negative impact on the firms’ innovation activity and productivity growth vis-à-vis nonrelocating comparison firms. In contrast, we find a positive link between domestic relocation activities and the firms’ propensity to introduce a product innovation. Firms should thus carefully account for potentially distorting performance effects when deciding about the spatial scale of relocation strategies in the short to mid-run. 相似文献

Australia's carbon‐pricing policy remains in doubt due to a lack of bipartisan political support. A survey of Australian‐based carbon‐pricing experts demonstrates profound policy uncertainty: 40 per cent of respondents expect the current carbon‐pricing mechanism to be repealed, but 80 per cent expect that there will be a carbon price in 2020. The forward price curve is U‐shaped and has great variance, with the 60 per cent confidence interval spanning from zero to A$25/t in 2020. Carbon policy uncertainty causes large excess costs in Australia's energy sector and may result in delay and diversion of investment. 相似文献

Minimum-variance portfolios, which ignore the mean and focus on the (co)variances of asset returns, outperform mean–variance approaches in out-of-sample tests. Despite these promising results, minimum-variance policies fail to deliver a superior performance compared with the simple 1/N rule. In this paper, we propose a parametric portfolio policy that uses industry return momentum to improve portfolio performance. Our portfolio policies outperform a broad selection of established portfolio strategies in terms of Sharpe ratio and certainty equivalent returns. The proposed policies are particularly suitable for investors because portfolio turnover is only moderately increased compared to standard minimum-variance portfolios. 相似文献

Over the past decade, an increasing number of authors have been examining the nexus of producer versus consumer responsibility, often dealing with the question of how to assign responsibility for internationally traded greenhouse gas emissions. Recently, a similar problem has appeared in drafting the standards for the Ecological Footprint: While the method traditionally assumes a full life-cycle perspective with full consumer responsibility, a large number of producers (businesses and industry sectors) have started to calculate their own footprints (see www.isa.org.usyd.edu.au). Adding any producer's footprint to other producers' footprints, or to population footprints, which all already cover the full upstream supply chain of their operating inputs, leads to double-counting: The sum of footprints of producers and consumers is larger than the total national footprint. The committee in charge of the Footprint standardisation process was hence faced with the decades-old non-additivity problem, posing the following dilemma for the accounting of footprints, or any other production factor: if one disallows double-counting, but wishes to be able to account for producers and consumers, then one cannot impose the requirement of full life-cycle coverage; the supply chains of actors have to be curtailed somehow in order to avoid double-counting. This work demonstrates and discusses a non-arbitrary method of consistently delineating these supply chains, into mutually exclusive and collectively exhaustive portions of responsibility to be shared by all actors in an economy. 相似文献

Feasible and profitable business models to better integrate and harness decentrally generated renewable energy are expected to constitute a key element for the energy transition in Germany. Until now, generated electricity of decentralized systems is to the largest extent only used by the property owner directly or fed into the public grid. To make better use of the generated electricity, it is necessary to find business models that provide an opportunity for different market actors, such as municipal utilities and residential prosumers. Due to the importance, yet low-anticipated monetary potential of such solutions, the legislator encourages their implementation by exemption of statutory fees, levies and taxes as well as by offering public remunerations, premiums and compensations in some cases. Capitalizing on these benefits, however, is only feasible under compliance with the legal requirements. In the light of the considerations above, this work states and analyzes the legal and regulatory framework of different business models within the German energy landscape. The major aim is to identify opportunities and challenges for the implementation of the business models self consumption, direct consumption, direct marketing, demand response, community electricity storage and net metering at the municipal level. The findings show that the profitability of various decentralized on-site business models depends primarily on the current statutory cost exemptions and compensations. At the same time, the regulation is characterized by unsystematic specific exemptions which leads to uncertainty regarding long-term planning. Additionally, although not directly privileged by the existing legal framework, municipal utilities are better suited to handle the legal burdens due to their experience and their administrative infrastructure. 相似文献

We evaluate how the productive structure and level of specialization of a hospital affect technical efficiency by analyzing
a six-year panel database (2000/2005) drawn from hospital discharge records and Ministry of Health data. We adopt a distance
function approach, while measuring the technical efficiency level with stochastic frontier techniques. After controlling for
environmental variables and hospital case-mix, inefficiency is negatively associated with specialization and positively associated
with capitalization. Capitalization is typical of private structures which, on average, use resources less efficiently with
respect to public and not-for-profit hospitals. Finally, by looking at scale elasticities, we find some evidence of unexploited
economies of scale, leaving room for centralization. 相似文献

The German communities cover their need for a general liability insurance mainly by using Municipal Loss Compensation (Kommunale Schadenausgleiche — KSA). Being an association without legal capacity as it is understood in § 54 Abs. 1 BGB (nicht rechtsfähiger Verein), the KSA can have rights and duties just like a partnership under the German Civil Code (Gesellschaft bürgerlichen Rechts). As a third-party supplier the KSA is a company in terms of § 99 Abs. 1 GWB (Law Against Restraints on Competition). Thus, the communities are to observe European Public Procurement Law when founding a KSA or when joining one. The ?in-house“-jurisprudence of the European Court of Justice is not applicable and therefore does not constitute an exemption of the European Public Procurement Law. 相似文献
