Abstract We conduct an update of the ranking of economic journals by Kalaitzidakis, Mamuneas, and Stengos (2003) . However, our present study differs methodologically from that earlier study in an important dimension. We use a rolling window of years between 2003 and 2008, for each year counting the number of citations of articles published in the previous 10 years. This allows us to obtain a smoother longer view of the evolution of rankings in the period under consideration and avoid the inherent randomness that may exist at any particular year, because of new entrants. 相似文献

In the nonparametric measurement of allocative efficiency, output prices are fixed. If prices are endogenous, the overall output in the market determines the allocative efficient point. We develop an alternative semi-nonparametric model that allows prices to be endogenously determined. 相似文献

We investigate the comovements of the log of earnings, dividends, and stock prices by testing for the number of common stochastic trends among these series. We find that the three series are cointegrated with a single cointegrating vector. Our findings collectively imply that (i) there is an equilibrium force that tends to keep these series together over time, (ii) changes in dividends are primarily influenced by changes in some measure of permanent earnings, and (iii) a substantial fraction of stock price movement is driven by neither earnings changes nor dividend changes. When we take into account the cointegration relationship, we find that the dynamic relationship between these variables is significantly affected. We present a common stochastic trends model of earnings, dividends, and stock prices, whose implications are broadly consistent with these findings. 相似文献

We show, using the modified rescaled range statistic, that none of the return series of indices of five European countries, the United States and Japan exhibits long term dependence. This statistic — introduced by Lo (1991) — correct Hurst's (1951) ‘classical’ rescaled range statistic for short term dependence. We also report the classical rescaled range statistic after adjusting the series for short term dependence. This procedure shows, for cases where the results of the modified rescaled range statistic are mixed, that no long term dependence can be found. Simulations indicate reasonable power of this adjustment procedure. Furthermore, we find that estimates of the Hurst exponent, a related measure of long term dependence, are also biased by short term dependence. Simulations show that this measure — that has recently attracted growing interest — cannot distinguish between models with or without long term dependence. 相似文献

This paper studies the price‐setting problem of a monopoly that in each time period has the option of failing to deliver its good after receiving payment. The monopoly may be induced to deliver the good if consumers expect that the monopoly will not deliver in the future if it does not deliver today. If the good is nondurable and consumers are anonymous, the monopoly's optimal strategy is to set a price equal to the static monopoly price each period if the discount factor is high enough, and otherwise to set the lowest price at which it can credibly promise to deliver the good. If the good is durable, we derive an intuitive lower bound on the monopoly's optimal profit for any discount factor and show that it converges to the optimal static monopoly profit as the discount factor converges to 1, in contrast to the Coase conjecture. We also show that rationing the good is never optimal for the monopoly if there is an efficient resale market and that the best equilibrium in which the monopoly always delivers involves a strictly decreasing price path that asymptotes to a level strictly above the ratio of the monopoly's marginal cost to the discount factor. 相似文献

This paper analyses the relationship between production subsidies and firms’ export performance using a very comprehensive and recent firm‐level database and controlling for the endogeneity of subsidies. It documents robust evidence that production subsidies stimulate export activity at the intensive margin, although this effect is conditional on firm characteristics. In particular, the positive relationship between subsidies and the intensive margin of exports is strongest among profit‐making firms, firms in capital‐intensive industries, and those located in non‐coastal regions. Compared to firm characteristics, the extent of heterogeneity across ownership structure (SOEs, collectives, and privately owned firms) proves to be relatively less important. 相似文献

Several methods have been developed for filtering seasonal influences and extreme returns in financial and economic time series. The theoretical support for these approaches is rather questionable since it focuses on the effects of shocks on prices and not on their sources. Removing such effects modifies the true generating system of market dynamics because of the non-proportional character of non-linearity. Thus, taking into account that the underlying process of economic time series is highly non-linear we cannot be certain a priori what the impact of new information will be on the dynamic structure of a system. The main contribution of this paper is to demonstrate using the methodology of simulations the eventual distortions in time series data arising from the arrival of news when agents follow non-linear trading strategies. We argue that if news can really modify the dynamical behaviour of a system, then the methodology of filtering exogenous distortions needs to be re-examined. 相似文献

Australian studies have focused on different dimensions of intra industry trade (IIT) between the manufacturing sector and the rest of the world at the disaggregated level, i.e. 1, 2, 3, 4 or 5 digit levels. The current study seeks to complement the existing literature by examining the IIT and hence output and employment performance of two different digit industries in the form of the textile, clothing and footwear (TCF) (2 digit) and motor vehicle (4 digit) industries because they are characterized by different factor intensity in production. Specifically, the former is fundamentally labour intensive whilst the latter is capital intensive in production. The central results reveal that the motor vehicle industry has exhibited a superior IIT and hence output and employment performance as compared to the TCF industry, as well as the manufacturing sector. The sophisticated capital goods produced and the capital intensive nature of motor vehicle production have made it possible to derive the cost benefits of large scale production which in turn has led to stronger export penetration. Moreover, the industry specific assistance measures which have been biased towards tax incentives for investment and R&D expenditure have favoured the motor vehicle industry's production and exports at the expense of the TCF industry, thereby reinforcing the former industry's stronger IIT and hence output and employment performance. 相似文献

The Productivity Commission claims on the basis of computable general equilibrium modelling that a seemingly small reduction in assistance to the Australian Automotive industry (a cut in tariffs from 10 per cent to 5 per cent and elimination of the ACIS scheme) would generate an annual welfare benefit of about $500 million. I explain that this implausible result rests on an implicit manna‐from‐heaven assumption. Using results published by the Commission, I rework their welfare calculations. With parameter values favoured by them, the corrected annual welfare gain is $66 million. With what I consider more realistic parameter values, the welfare effect is negative. 相似文献

We establish a link between von Neumann-Morgenstern stable set and the Nash solution in a general n-player utility set. The stable set-solution is defined with respect to a dominance relation: payoff vector u dominates v if one player prefers u even with one period delay. We show that a stable set exists and, if the utility set has a smooth surface, any stable set converges to the Nash bargaining solution when the length of the period goes to zero. 相似文献
