This paper proposes an asymmetric autoregressive conditional duration (ACD) model, which extends the ACD model of Engle and Russell (1998). The asymmetry consists of letting the duration process depend on the state of the price process. If the price has increased, the parameters of the ACD model can differ from what they are if the price has decreased. The model is applied to the bid-ask quotes of two stocks traded on the NYSE and the evidence in favour of asymmetry is strong. Information effects (Easley and O'Hara 1992) are also empirically relevant. As the model is a transition model for the price process, it delivers `market forecasts' of where prices are heading. A trading strategy based on the model is implemented using tick-by-tick data.While remaining responsible for any error in this paper, the authors would like to thank R. Anderson, G. Le Fol, C.

The goal of this paper is to highlight the importance of the concept of choice. To do so, a synopsis of the most important contributions to this topic—featuring an eclectic set of scholars across disciplines—is provided. As central to the argument, John von Neumann’s contributions, game theory and simulation techniques on von Neumann machines, are identified. Innovation (economic and theoretic) as the driving force behind human evolution seems to head for a new scientific paradigm based on von Neumann’s ideas.

This study investigates linear and nonlinear price information flows between the Chinese Stock Index 300 (CSI300) and futures market using high-frequency data and their wavelet transformed series for three regimes for which stock short-selling restrictions in China are different. Empirical results generally indicate information feedback between these two markets regardless of assumptions of linear and nonlinear causality and regimes for original series and wavelet transformed data at different scales.  相似文献

This paper examines the relationship between retail petrol prices, excise duties and crude oil prices in the UK over the period 1973–1988. The existence of a stable relationship between the petrol price, level of excise duty and spot oil price is confirmed through use of the cointegration approach. Although the speed of reaction of petrol prices to changes in the crude price depends on whether crude prices are rising or falling, any asymmetry in the pricing response is virtually absent after an adjustment period of only four months.  相似文献

This paper investigates the dynamics of the price level in a continuous time monetary version of the Yaari-Blanchard overlapping generations model with capital accumulation. It is shown that there is an interaction between fiscal discipline and price stability when the government budget is intertemporally balanced. Relevant implications are that high debt and slow adjustment adversely affect both prices and capital accumulation.

This article sheds light on the underlying mechanisms behind the changes in the value relevance of accounting information in the Karachi Stock Exchange (KSE) during the 1999–2010 period. We find that neither changes in earnings quality nor the earnings lack of timeliness hypothesis can explain the decline in the value relevance of accounting information in the KSE. Based on the stylized facts associated with the growth of the KSE and the broader economics literature, we argue that the reduction in the explanatory power of accounting information vis-à-vis stock returns was caused by herding behaviour. Empirical estimates from state-space model of herding behaviour confirm the existence of herding, and we find that the value relevance of accounting information is significantly lower in periods characterized by herding behaviour. This article is also amongst the first attempts to empirically demonstrate that an expansionary monetary policy and increases in foreign portfolio investment lead to increased levels of herding.  相似文献

In a 1976 Journal of Political Economy paper, Chen has shown that gross substitutability is a necessary and sufficient condition for the deletion of a desirable currency denomination to be inflationary. The present note corrects and extends the theory by showing that such deletion is inflationary even if monies are complements.  相似文献

This paper analyses the disinflationary policy pursued in Denmark since October 1982, focusing on the Phillips curve trade-off and the credibility of this disinflationary policy. The overall conclusion confirms no significant indication of the disinflationary policy being credible.  相似文献

We assess monetary equilibrium theory by focusing on its foundation—price stickiness—and answer several ancillary questions. Prices are sticky at times. Contra monetary equilibrium theorists, this is not a reason to advocate an issuance of fiduciary media to counteract the effects of a sluggish price adjustment process. Issuances of fiduciary media will breed negative effects, primarily via wealth redistributions, faulty interest rate signals and exacerbated business cycles. Allowing the price level to adjust to maintain monetary equilibrium provides for fewer detrimental effects than adjusting the supply of credit.  相似文献

This paper explores the dynamic inter-relationships among the currency exchange rate, consumer price inflation, and real output growth, as well as the roles of money and interest rates in output and price determination. Time series data and vector autoregression models are used. Results suggest that there are significant inter-relationships between the exchange rate and inflation, monetary shocks matter only when explaining money itself and the price level, and interest rate-dependent monetary policies in the absence of financial modernization are ineffective  相似文献

A substantial theoretical and experimental literature has focused on the conditions under which cooperative behavior among actors providing public goods or extracting common-pool resources arises. The literature identifies the importance of coercion, small groups of actors, or the existence of social norms as conducive to cooperation. This research empirically investigates cooperative behavior in a natural resource extraction industry in which the provision of a public good (bycatch avoidance) in the Alaskan flatfish fishery is essential to the duration of the fishing season, and an information provision mechanism exists to relay information to all individuals. Using a mixed logit model of spatial fishing behavior our results show that conditionally cooperative behavior is prevalent but deteriorates as bycatch constraints tighten.  相似文献

The issue regarding the impact of information technology on organizations is here reconsidered by applying a new analytical framework. Information technology affects the cost of transactions which take place under alternative institutional arrangements, such as markets, bureaucracies and groups; technology can affect the efficiency of the organizations which apply it and the organizational behaviour of their members. Empirical data show how computerization changes organizational patterns according to efficiency considerations. An enlargement of the framework to take into account alternative mechanisms for organizational participation, such as exit, voice and loyalty, allows to examine the impacts of information technology on participation possibilities within organizations.  相似文献

The paper examines the effect of heterogeneous consumer trade-offs - between environmental performance, quality of service characteristics, and price - on the generation and diffusion of environmentally benign technology paradigms. We find that the direction, timing, and environmental impact of new paradigms is shaped by the distribution of consumer trade-offs. Of key importance are the initial distributions of consumer preferences, and how those distributions evolve over time. This has serious implications on environmental pollution, and for policy makers seeking to influence the ‘greening’ of consumer demand.  相似文献

Within knowledge-based economies, one of the major forms of organisational change concerns the impact of the introduction and dissemination of information and communication technologies on markets, consumers and firms. The existence of virtual or ‘electronic’ communities is one of the main consequences of this impact. In this context, the main purpose of this article is to answer the following questions: Why do firms and consumers take part in these communities? Are they driven by the usual or by more specific motivations based on reciprocity or we-rationality? Do these potentially new types of organisation and interaction, and new motivations change the working and the dynamics of our economic systems?  相似文献

This paper evaluates the inertial inflation hypothesis for Brazil. The hypothesis posits that indexation created a feedback mechanism such that one-time supply shocks were fully transmitted into permanent changes in inflation. A theoretical model is used to show that this outcome is based on the assumption of perfect price flexibility. However, with price stickiness indexation does not produce inertial inflation. The degree of inertia is then compared for two periods: one without indexation (1945–1963), and one with indexation (1969–1985). Finally, vector-autoregressive representations are estimated for the latter period, allowing for price stickiness. The empirical results do not support the hypothesis.  相似文献
