The goal of this paper is to present quantitative tools to manage competition policy analysis in two-sided platforms, based on a common framework for transaction and non-transaction platforms. We explore tools for relevant market definition [Critical Loss Analysis and a small but significant non-transitory increase in price (SSNIP) test], unilateral effects indicators [Upward Pricing Pressure (UPP) and Gross Upward Pricing Pressure Index (GUPPI)] and tests for exclusionary practices. We review dispersed results in the literature and fill the gaps where appropriate. We highlight the required changes from the usual one-sided market framework and tools. While discussions of antitrust tools can be found in specialized forums devoted to advances in competition policy analysis, we organize the material in an integrated framework. 相似文献

ABSTRACTThis study examines how experiential value as perceived by customers of Korean family restaurants influences consumption emotions, self-connective attachment to the restaurant brand, and, ultimately, brand loyalty. Having conducted a comprehensive literature review, the study proposes and estimates a model that specifies the interrelationships among four dimensions of experiential value (i.e., atmosphere, escapism, customer return on investment, and service excellence), and latent variables of positive and negative emotions, self-connective attachment, and brand loyalty. Analysis with structural equation modeling was conducted with data collected from customers of family restaurants in South Korea. The results show that dimensions of experiential value influence either positive or negative emotions. The emotion variables, together with self-connective attachment, also mediate the relationships between perceived value of dining experience and brand loyalty. 相似文献

Summary. In this paper we consider a two-period general equilibrium model with uncertainty and real assets as financial instruments. The novelty of the analysis is that real assets are the stocks of neoclassical firms, so that both returns and yields depend on anticipated spot goods prices (and, of course, the yield matrix may change rank with prices). Assuming that financial markets are potentially complete, we establish generic existence of financial equilibrium and prove that there exists a dense set of economies such that financial equilibria are efficient.Received: 19 April 2001, Revised: 23 April 2003, JEL Classification Numbers:

abstract In this paper, we explore the standardization of contemporary management knowledge, focusing in particular upon the role of ‘standards’ in creating and reifying ‘organizational objects’, with powerful consequences and with often unrecognized ethical implications. It is our argument that modernist beliefs in ‘general, abstract and timeless ideas’ ( Brunsson et al., 2000 , p. 173), enshrined in a universal and abstract rationality, results in the marginalization of more reflexive forms of rationality and the suppression of autonomy, creativity and discretion in organizations. To investigate the consequences of standardization, we take as the focus of our analysis a specific management model which has a significant and growing impact on many sectors of contemporary industry; that of project management. Drawing on the work of Timmermans and Berg (1997) , Bowker and Star (1999) and Brunsson et al. (2000) , we draw attention to the reification of the object of management; in this case, the project itself, as a transhistorical, ‘real world’ object. By tracing efforts to establish and institutionalize ‘standards’ in this and other fields of management, in particular through the creation and dissemination of a universal ‘body of knowledge’ for this field, we draw attention to the political and moral significance of the ‘blackboxing’ of knowledge. It is our broader intention here to help to denaturalize this organizational object, to legitimize other modes of knowledge and practice in the field, and thereby to reopen debate in this and other arenas of standardization. 相似文献

With a sample of Australian at‐risk gamblers, this research examines the impact of gender and individual difference in experiential avoidance (EA; cognitive and emotional suppression) on the processing of fear appeals. Study 1, through thematic analysis, explores fear appeal perceptions among at‐risk gamblers. The results identify that relevant threats, such as social and psychological, should be integrated into fear‐inducing advertising stimuli. Study 2 uses multigroup comparisons in structural equation modeling (SEM) to test the robustness of the revised protection motivation model (RPMM) in predicting the effectiveness of fear appeals to induce help‐seeking intentions in at‐risk gamblers. This research examines the boundary conditions of the RPMM through the moderating roles of gender and EA. The results provide evidence that fear partially mediates the impact of perceived susceptibility (PS) on help‐seeking intentions in low experiential avoiders, whereas high experimental avoiders resist fear elicitation. Furthermore, evoked fear does not lead to help‐seeking intentions in male at‐risk gamblers. In female at‐risk gamblers, while fear prompts help‐seeking intentions, PS (i.e., probability of harm) does not translate to behavioral intentions via fear. For both genders and low and high experiential avoiders, cognitive appraisals of PS significantly and positively impact help‐seeking intentions. This research demonstrates the unique roles of gender and EA on fear appeal effectiveness in at‐risk gamblers. 相似文献

ABSTRACT This paper aims to understand how a brand’s price level, relative to its competitors, will affect consumers’ responses to price changes of the brand. The study uses experiments to examine brand choice responses to price increases and decreases across contexts differing in competitor brands and their respective prices. These experiments are conducted with six consumer goods categories. The research identifies three key factors that affect the size of responses to brand price changes – (1) passing a competitor brand’s price, (2) narrowing versus widening the price gaps with competitors, and (3) whether competitors are predominantly higher or lower priced brands. 相似文献

Innovation in food service technology offers differentiation and cost leadership in strategic terms. The majority of food service businesses do not have research and development laboratories. At present, the innovations in equipment design and layout, packaging and service techniques are of a defensive or reactive nature. Examples of defensive innovation include faster and better preparation methods, improved temperature control, even heating, energy and labour savings, less waste, better sanitation, faster service and flexibility. In contrast, developments in offensive or pro-active innovation, which can radically change current practices, are rare. Novel food service processes can evolve as a result of adoption of technological breakthroughs in “high tech” fields of the economy. This justifies investments in offensive research and highlights the importance of technical competencies for a food service professional. 相似文献

This paper provides a general framework for pricing of perpetual American and real options in regime-switching Lévy models. In each state of the Markov chain, which determines switches from one Lévy process to another, the payoff stream is a monotone function of the Lévy process labeled by the state. This allows for additional switching within each state of the Markov chain (payoffs can be different in different regions of the real line). The pricing procedure is efficient even if the number of states is large provided the transition rates are not very large w.r.t. the riskless rates. The payoffs and riskless rates may depend on a state. Special cases are stochastic volatility models and models with stochastic interest rate; both must be modeled as finite-state Markov chains. As an application, we solve exit problems for a price-taking firm, and study the dependence of the exit threshold on the interest rate uncertainty. 相似文献

Abstract The objective of this paper is to investigate dynamic properties of age trajectories of physiological indices and their effects on mortality risk and longevity using longitudinal data on more than 5,000 individuals collected in biennial examinations of the Framingham Heart Study (FHS) original cohort during about 50 subsequent years of follow-up. We first performed empirical analyses of the FHS longitudinal data. We evaluated average age trajectories of indices describing physiological states for different groups of individuals and established their connections with mortality risk. These indices include body mass index, diastolic blood pressure, pulse pressure, pulse rate, level of blood glucose, hematocrit, and serum cholesterol. To be able to investigate dynamic mechanisms responsible for changes in the aging human organisms using available longitudinal data, we further developed a stochastic process model of human mortality and aging, by including in it the notions of “physiological norms,” “allostatic adaptation and allostatic load,” “stress resistance,” and other characteristics associated with the internal process of aging and the effects of external disturbances. In this model, the persistent deviation of physiological indices from their normal values contributes to an increase in morbidity and mortality risks. We used the stochastic process model in the statistical analyses of longitudinal FHS data. We found that different indices have different average age patterns and different dynamic properties. We also found that age trajectories of long-lived individuals differ from those of the shorter-lived members of the FHS original cohort for both sexes. Using methods of statistical modeling, we evaluated “normal” age trajectories of physiological indices and the dynamic effects of allostatic adaptation. The model allows for evaluating average patterns of aging-related decline in stress resistance. This effect is captured by the narrowing of the U-shaped mortality risk (considered a function of physiological state) with age. We showed that individual indices and their rates of change with age, as well as other measures of individual variability, manifested during the life course are important contributors to mortality risks. The advantages and limitations of the approach are discussed. 相似文献

Summary We explicitly solve the pricing problem for perpetual American puts and calls, and provide an efficient semi-explicit pricing procedure for options with finite time horizon. Contrary to the standard approach, which uses the price process as a primitive, we model the price process as the expected present value of a stream, which is a monotone function of a Lévy process. Certain processes exhibiting mean-reverting, stochastic volatility and/or switching features can be modeled this way. This specification allows us to consider assets that pay no dividends at all when the level of the underlying stochastic factor is too low, assets that pay dividends at a fixed rate when the underlying stochastic process remains in some range, or capped dividends.The authors are grateful to the anonymous referees for valuable comments and suggestions. 相似文献
