Since the introduction of the Autoregressive Conditional Heteroscedasticity (ARCH) model, the literature on modeling the time-varying second-order conditional moment has become increasingly popular in the last four decades. Its popularity is partly due to its success in capturing volatility in financial time series, which is useful for modeling and predicting risk for financial assets. A natural extension of this is to model time variation in higher-order conditional moments, such as the third and fourth moments, which are related to skewness and kurtosis (tail risk). This leads to an emerging literature on time-varying higher-order conditional moments in the last two decades. This paper outlines recent developments in modeling time-varying higher-order conditional moments in the economics and finance literature. Using the Generalized Autoregressive Conditional Heteroscedasticity (GARCH) framework as a foundation, this paper provides an overview of the two most common approaches for modeling time-varying higher-order conditional moments: autoregressive conditional density (ARCD) and autoregressive conditional moment (ARCM). The discussion covers both the theoretical and empirical aspects of the literature. This includes the identification of the associated skewness–kurtosis domain by using the solutions to the classical moment problems, the structural and statistical properties of the models used to model the higher-order conditional moments and the computational challenges in estimating these models. We also advocate the use of a maximum entropy density (MED) as an alternative method, which circumvents some of the issues prevalent in these common approaches.  相似文献

This paper deals with the design of regulatory mechanisms for oligopolistic industries. The proposed incentive scheme consists of two parts: a subsidy depending upon a firm's contribution to an equilibrium price reduction, and a tax equal to the profit of the previous period. This mechanism is as effective in regulating oligopolies as the well-known incremental surplus subsidy scheme in a monopoly framework. The proposed scheme provides appropriate incentives to enforce competitive behavior in a Cournot oligopoly. The scheme is welfare improving even if firms collude.  相似文献

The wealth effects for shareholders of American financial firms involved in foreign acquisitions and also the wealth effects for shareholders of U.S. target firms acquired by foreign concerns are the topics of this study. The findings indicate that stockholders of U.S. bidding financial firms (and its subset of banks) earn neither abnormal gains nor suffer abnormal losses upon the announcement of an acquisition or regulatory approval. On the other hand, stockholders of U.S. target financial firms (and its subset of banks) earn significant abnormal profits at both the announcement of the proposed acquisition and the announcement of regulatory approval of the acquisition. The wealth effects for these two samples are also compared to samples in which both parties to the acquisition are U.S. firms. The research suggests that there is no significant difference in the size of the announcement gains or losses for either stockholders of the target or bidding firms based on whether the acquisition is foreign or domestic. These findings conflict with prior research which indicates that, for firms in general, stockholders of U.S. targets earn significantly greater wealth benefits when they are acquired by foreign firms than by domestic firms. Overall, these results are consistent with a competitive market for acquisitions of financial firms in which buyers do not earn or lose at the announcement of an acquisition, and in which abnormal gains are received only by the sellers.  相似文献

Between 1955 and 1987, Austrian trade with Eastern Europe was characterized by specific factors. On the one hand, trade flows were influenced by the central planning system in Eastern Europe. On the other hand, Austria applied non-standard policy tools to manage Eastern trade. Furthermore, Austrian trade with Eastern Europe was affected by the implementation of the free trade agreement with the European Communities (EC) and the change in the institutional framework for Eastern trade in the early 1970s. Austrian Eastern exports were fostered by increased export subsidies and barter trade. We assess the net effects of these contradictory measures of trade policy by estimating aggregate import and export equations and testing for a structural break in 1973. Our results are consistent with the view that Austria subsidized Eastern exports to pursue a countercyclical policy after 1973.

Most professional women step off the career fast track at some point. With children to raise, elderly parents to care for, and other pulls on their time, these women are confronted with one off-ramp after another. When they feel pushed at the same time by long hours and unsatisfying work, the decision to leave becomes even easier. But woe to the woman who intends for that exit to be temporary. The on-ramps for professional women to get back on track are few and far between, the authors confirm. Their new survey research reveals for the first time the extent of the problem--what percentage of highly qualified women leave work and for how long, what obstacles they face coming back, and what price they pay for their time-outs. And what are the implications for corporate America? One thing at least seems clear: As market and economic factors align in ways guaranteed to make talent constraints and skill shortages huge issues again, employers must learn to reverse this brain drain. Like it or not, large numbers of highly qualified, committed women need to take time out of the workplace. The trick is to help them maintain connections that will allow them to reenter the workforce without being marginalized for the rest of their lives. Strategies for building such connections include creating reduced-hour jobs, providing flexibility in the workday and in the arc of a career, removing the stigma of taking time off, refusing to burn bridges, offering outlets for altruism, and nurturing women's ambition.  相似文献

Sustainable Consumption Governance: A History of Promises and Failures   总被引:1,自引:0,他引:1  
What are the implications of the current international political, and economic settings for consumer policy, and, in particular, those regarding sustainable consumption? In terms of improvements in the efficiency of consumption, the settings have induced efforts to this effect and show potential for further progress. In terms of necessary changes in consumption levels and patterns, however, little progress has been made since the Rio Summit nor is there likely to be any in the near future. These two dimensions of sustainable consumption need to be differentiated, as there is a substantial amount of controversy regarding our ability to achieve sustainable consumption on the basis of improvements in efficiency alone. The paper traces these differences with respect to the work of the major international governmental organizations (IGOs) engaged in developing sustainable consumption governance. It argues that the lack of commitment to strong sustainable consumption among IGOs can be explained by their “weakness” as actors in global governance and the existence of strong opposing interests among consumers and business actors.  相似文献

Neoclassical and Austrian/evolutionary economic paradigms have different implications for integrating corporate social responsibility (corporate citizenship) and competitive strategy. Porter’s “Five Forces” model implicitly rests on neoclassical theory of the firm and is not easily reconciled with corporate social responsibility. Resource-based models of competitive strategy do not explicitly embrace a particular economic paradigm, but to the extent their conceptualization rests on neoclassical assumptions such as imperfect factor markets and profits as rents, these models also imply a trade-off between competitive advantage and corporate social responsibility. Differences in Austrian/evolutionary economic model’s assumptions about equilibrium, profits, and other economic concepts allow this paradigm to embrace alternative views of strategy such as the activities or dynamic capabilities views. These alternative views of strategy focus on learning and adaptation; they align more easily with corporate social responsibility. In practice this alignment comes about because social engagement facilitates the learning and adaptation that are a source of competitive advantage. Among the many business arguments for CSR such as improved employee morale/productivity or brand differentiation, this view prioritizes innovation.  相似文献

Continuous models of respondent heterogeneity assume the existence of a response function where variables of interest are continuously related to explanatory variables. In many situations this assumption may not be true. In this paper we propose an approach of modeling respondent heterogeneity that identifies abrupt changes in the distribution of response coefficients around a threshold specification. Our model differs from traditional threshold models by introducing the threshold effect to describe across-unit behavior as opposed to within-unit behavior. We illustrate our proposed Bayesian threshold model for survey data from a large national retail bank that examines the effects of service wait times on customer satisfaction. We find evidence of a threshold effect where long in-process wait times are associated with bank branches characterized by weak associations between service quality drivers and overall perceptions of service quality. Branches with wait times below the threshold are found to have much stronger associations.  相似文献
