Japan has been in a benign liquidity trap since the 1990s. In a benign liquidity trap, interest rates approach zero and monetary policy is ineffective but output and employment perform decently. Such a pattern contradicts traditional macro theories. This paper introduces a monetary general equilibrium model that is compatible with Japan's performance and resolves puzzles associated with liquidity traps. Possible conclusions for Anglo‐Saxon countries and eurozone members are also discussed. 相似文献

R&D externalities can imply ranges of aggregate increasing returns to scale in R&D. As a consequence several equilibria can exist involving different numbers of firms and different R&D investment levels. In a theoretical model the equilibrium dynamics are analyzed, showing that cyclical fluctuations of the number of firms and R&D investment may be expected, and that the long-run equilibrium is highly sensitive to investors' initial beliefs. The model is tested empirically using a unique database comprising competing firms in various R&D races. 相似文献

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

Adaptive customization systems are common in the delivery of e-service. However, consumers vary in their reaction to these systems. We introduce computer-mediated customization tendency (CMCT), a composite individual difference variable that reflects a consumer's personal preferences for designing and interacting with adaptive online environments to create valuable e-service experiences. To measure CMCT, we developed a formative index composed of need for control, technology innovativeness, and aesthetic appreciation. The results show CMCT influences adaptive online behavior and the perceived value of the adaptive e-service experience. In addition, customization-prone and customization-averse consumers differ in how they perceive the costs, benefits, and overall value of the experience. 相似文献

The concern and study of supply risk and supply continuity has recently come to the forefront in managing business and conducting research. This empirical study of U.S. and German firms investigates the relationship between perceived supply risk sources and supply disruption occurrence, as well as the use of supply chain resiliency practices to reduce disruption frequency. We demonstrate that supply managers' concerns with risk emanating from suppliers and the supply market are positively related to supply disruption occurrence. We further show how and when implementing flexibility and redundancy may reduce the effects of supply disruptions. 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
