Companies have learned that radical innovations (RIs) are a prerequisite to grow organically. However, companies struggle to identify and introduce RIs, as their inherent high uncertainties and novelty challenge established organisations and management routines. To address the first challenge, companies need to take a holistic approach and design a trans‐boundary environment of creativity, trans‐disciplinary and entrepreneurial spirit. This environment attracts and retains visionary people, fosters generation of new opportunities and cultivates adaptability. By adapting evaluation metrics for RI, setting up flexible processes, and promoting trans‐disciplinary exchange, the second challenge can be addressed. Increased research has concentrated on several aspects of RI lately, but so far a combining framework is missing. Our paper bridges this gap by developing an improved theoretical framework, enhancing the existing literature and introducing art as a method to advance trans‐disciplinary interchange. In a case‐study approach, we have applied our framework to the research and development department of Vodafone Research and Development, Germany, as they integrate art methodically in their research and development process. Analysing their RI capabilities, we identify the trans‐disciplinary exchange with artists as a novel initiator and driver of RI, which has not yet been adequately considered. 相似文献

Mit dem Bilanzrechtsmodernisierungsgesetz wollte der Gesetzgeber unter anderem eine im Verh?ltnis zu den IFRS gleichwertige,
d. h. ebenso entscheidungsnützliche, aber einfachere und kostengünstigere Alternative bieten. Um dieses Ziel zu erreichen,
wurden verschiedene Wahlrechte gestrichen, Bilanzierungsverbote aufgehoben und Bilanzierungsmethoden ver?ndert. Aus Sicht
der Abschlusspolitik wurden damit einerseits explizite Wahlrechte verringert und andererseits implizite Wahlrechte geschaffen.
Zudem bergen auch die übergangsvorschriften abschlusspolitisches Potenzial. Nach einer Einordnung der Abschlusspolitik und
der Herausarbeitung der konkreten Potenziale werden die Konsequenzen in Bezug auf die Entscheidungsnützlichkeit diskutiert
und die m?glichen Auswirkungen der ge?nderten Rechnungslegungsnormen am Beispiel der Bilanzierung von Pensionsverpflichtungen
deutscher IFRS-Anwender empirisch belegt. 相似文献

This paper is concerned with the study of insurance related derivatives on financial markets that are based on nontradable underlyings, but are correlated with tradable assets. We calculate exponential utility‐based indifference prices, and corresponding derivative hedges. We use the fact that they can be represented in terms of solutions of forward‐backward stochastic differential equations (FBSDE) with quadratic growth generators. We derive the Markov property of such FBSDE and generalize results on the differentiability relative to the initial value of their forward components. In this case the optimal hedge can be represented by the price gradient multiplied with the correlation coefficient. This way we obtain a generalization of the classical “delta hedge” in complete markets. 相似文献

In this paper we take a public choice perspective on strategic environmental policy and international environmental agreements. We examine cooperative and noncooperative environmental policies under governments that are either welfare maximizers (“good dictators”) or tax revenue maximizers (“Leviathans”). We show that Leviathans can perform better in terms of welfare and that good dictators can set higher taxes. We then analyze international environmental agreements and show that the breakdown of environmental cooperation can indeed lead to a welfare gain for all signatory countries. Considering a delegation game between governments, we find that a Pareto‐superior Leviathan outcome can be the unique Nash equilibrium. 相似文献

Recent empirical research using real estate data has supported the weak and semi-strong forms of the efficient markets hypothesis. Previous studies have not included an estimate of expected appreciation into the tests of market efficiency, thus raising a question about the reliability of the results. We first use a market model to test for market efficiency with results similar to those reported by others. We next use a dynamic multiple indicator, multiple cause (DYMIMIC) model, which extracts a vector of expected appreciation from the price data, to test market efficiency. This approach produces superior results and a stronger conclusion about the efficiency of housing markets. The results indicate limited adjustment delays which can be explained by the existence of high transactions and search costs. 相似文献

Although the resource‐based view of the firm has been written about extensively, the process by which firm assets are accumulated has not been explored in detail. That is, we know little about the micro‐level mechanisms by which assets are built, nor do we have sufficient empirical evidence why some assets are more difficult to imitate, trade, or substitute. In this exploratory paper, we attempt to provide a better understanding of asset accumulation via an empirical research program in pharmaceutical drug discovery. Using a combination of field research, discovery data from nine pharmaceutical firms, and data on 218 alliances involving new technologies for experimentation and testing, three causes affecting asset accumulation are identified and described. First, the difficulty of imitating a particular asset is affected by interdependencies with other assets. Second, trading of assets can be impeded by structural inertia in the core of a firm that is adopting the technology asset. And third, fully specifying all factors affecting imitation and trading ex ante is very difficult, if not nearly impossible, under conditions of rapid technological change. We propose that the complex interactions of these causes can give rise to imperfections in factor markets. Finally, implications for further research are discussed as well.

Breaking with the Notion of Social Contract: Constitutions as Based on Spontaneously Arisen Institutions 总被引:2,自引:2,他引:0
Stefan Voigt 《Constitutional Political Economy》1999,10(3):283-300
The newly emerging subdiscipline of constitutional economics is dominated by adherents to social contract theory although this approach has been severely criticized many a time. In recent years, an alternative approach in which constitutions are conceptualized as conventions has emerged. It is argued here that this alternative approach is a step in the right direction but still does not go far enough. The central hypothesis of the paper is that conceptualizing constitutions as based on spontaneously arisen institutions can help to solve some of the problems left unanswered by the constitutions-as-conventions view. 相似文献

Density versus Quality in Health Care Provision: Using Household Data to Make Budgetary Choices in Ethiopia 总被引:1,自引:0,他引:1
Usage of health facilities in Ethiopia is among the lowest inthe world; raising usage rates is probably critical for improvinghealth outcomes. The government has diagnosed the principalproblem as the lack of primary health facilities and is devotinga large share of the health budget to building more facilities.But household data suggest that usage of health facilities issensitive not just to the distance to the nearest facility butalso to the quality of health care provided. If the qualityof weak facilities were raised to that currently provided bythe majority of facilities in Ethiopia, usage would rise significantly.National data suggest that given the current density and qualityof service provision, additional expenditure on improving thequality of service delivery will be more cost-effective thanincreasing the density of service provision. The budget allocationrule presented in the article can help local policymakers makedecisions about how to allocate funds between improving thequality of care and decreasing the distance to the nearest healthcare facility. 相似文献
