The within‐group estimator (same as the least squares dummy variable estimator) of the dominant root in dynamic panel regression is known to be biased downwards. This article studies recursive mean adjustment (RMA) as a strategy to reduce this bias for AR(p) processes that may exhibit cross‐sectional dependence. Asymptotic properties for N,T→∞ jointly are developed. When ( log 2T)(N/T)→ζ, where ζ is a non‐zero constant, the estimator exhibits nearly negligible inconsistency. Simulation experiments demonstrate that the RMA estimator performs well in terms of reducing bias, variance and mean square error both when error terms are cross‐sectionally independent and when they are not. RMA dominates comparable estimators when T is small and/or when the underlying process is persistent.  相似文献

The 60-year-old Israeli-Palestinian conflict has deeply influenced the evolution of the Palestinian economy. In the last two decades political instability and the Israeli closure policy have generated protracted economic stagnation and poor capital formation. The paper describes the consequences on the Palestinian economy of existing high transaction costs and market fragmentation. We propose a simple one-sector Post-Keynesian model that describes Palestine as a demand-driven economy. We show that high transaction costs and market fragmentation discourage investment by curtailing expected profitability, reducing the size of the market and depressing entrepreneurs' animal spirits. In the short run, these two factors induce low levels of capacity utilization and low rates of capital accumulation. The situation is even more worrying in the long run when entrepreneurs can revise their expectations. Depressed animal spirits and low levels of capacity use give rise to a low-growth trap from which Palestine can hardly escape. We also highlight the possible positive impact of the removal of high transaction costs and of market fragmentation, and the ensuing beneficial effects on the long-run equilibrium values of capital accumulation and capacity use. The conclusions place these analytical results into the historical situation of the Palestinian economy, and consider what is needed, politically and economically, in order to establish a sustained development process.

Organizations investing in project management need to be assured of a concrete return. Without the ability to clearly define its value, project management joins the long line of initiatives (i.e., TQM, information systems, training, human resources) struggling to prove their worth to organizations. However, demonstrating a concrete value in organizations has been illusive and even paradoxical. This paper describes the conceptual model underlying a major international research project designed to yield a broad perspective on the value of project management. This model and research design will be of interest to researchers, project managers, professional organizations, and senior executives.  相似文献

In this paper the relationship between inflation and stock returns in Australia is examined. It is found that increases in the price level reduce the real level of the stock price index. However, it is also found that the question of whether persistent increases in inflation affect real returns cannot be addressed using the Australian data.  相似文献

An economic topology can have many uses to the academician, student and practitioner. Refining a topology of economic systems helps to bring together seemingly disparate characteristics and to point out potential long run trends. The progression of economic systems over time and also brief explanations of each system are given. We argue that most modem economic systems have some remnants of earlier forms, that is, most economies today are some mixture of what might be considered pure systems. Measurable characteristics to identify a particular system are developed that allows progress to or from a particular classification to be charted for individual countries.  相似文献

This study tests for the integration of money velocity movements among the major European Union countries. For this purpose, a new test is employed that allows one to confirm or reject integration on the basis of whether or not the first largest principal component, based on deviations of velocity growth rates from a base country, is stationary. Using monthly data covering the last 25 years, this study finds that integration was strongest during the 1970s and during 1983-92. These findings modify the institutionalist view that common financial developments have meant that velocities have moved together on an upward secular trend over the last 40 years. Developments with regard to currency substitution along with exchange rate policy and capital controls can affect relative interest rates and income movements and therefore the co-movements in money velocities.  相似文献

Dividend timing and behavior in laboratory asset markets   总被引:1,自引:0,他引:1  
Summary. This paper investigates the effect of dividend timing on price bubbles and endogenous expectations in twenty-six laboratory asset markets. In ten "A1" markets, a single dividend is paid at the end of the trading horizon. In nine "A2" markets, dividends are paid at the end of each trading period. In seven "A3" markets, some of the dividends are paid at the end of the trading horizon, and the rest are paid on a per-period basis. The results indicate that price bubbles are most likely in A2 markets, less likely in A3 markets, and least likely in A1 markets. Six distinct hypotheses are considered. The data suggest that the concentration of dividend value at a single point in time helps to create common expectations, and thus significantly reduce the incidence of bubbles. Also, the results underscore the difficulty facing econometric tests on field data where fundamental value has to be approximated.  相似文献

We exploit within-school variation in counselors and find that one additional counselor reduces student misbehavior and increases boys’ academic achievement by over one percentile point. These effects compare favorably with those of increased teacher quality and smaller class sizes.  相似文献

This paper examines the dynamics of inter-firm networks and introduces a conceptual framework for explaining why inter-firm networks change over time. The framework is based on the idea that patterns of inter-firm linkages are linked to the life cycle development of an industry. Special emphasis is placed on the role of appropriabiliy, i.e. a firm's ability to capture the profits generated by its innovations. The (trans)formation of inter-firm networks in three industries is examined and used to illustrate the relevance of the framwork. One important inference from our study is that public policy makers and manageers should take into account the phase of industry development before implementing policies to create and/or change inter-firm networks.  相似文献
