Competition policy attempts to address the potential for market failure by encouraging competition in service markets. Often, in wireless communication service markets, national regulatory authorities seek to encourage entry via the spectrum assignment process. Instruments used include the assignment mode (auction or beauty contest), setting aside licenses and providing bidding (price and quantity) credits for potential entrants, and making more licenses (spectrum blocks) available than there are incumbent firms (excess licenses). The empirical analysis assesses the effectiveness of these policy instruments on encouraging entry. The econometric results show that the probability of entry is enhanced by using auction assignments and excess licenses. Furthermore, quantity, but not price, concessions encourage entry. 相似文献

AbstractOur paper examines the long-run relation between economic growth and current account equilibrium in Vietnam, using a multicountry balance-of-payments-constrained growth model. We find that for the whole sample (1985–2010) Vietnam grew less than the rate predicted by the model. We also find that the balance-of-payments-constrained growth rate shifted after the 1997 Asian crisis. Since the relative price effect is neutral, the volume effects dominate in setting the balance-of-payments constraint. On the one hand, owing to the high income elasticities of exports, growth in advanced countries has a strong multiplier effect on the Vietnamese economy. On the other hand, this effect is hindered by a strong “appetite” for imports coming from Asia. Finally, we assess the impact of the current crisis on Vietnam’s growth for the period 2011 to 2017. 相似文献

Zusammenfassung Kausalit?t und Lohn-Preis-Inflation in Westdeutschland 1964–1979. — In diesem Aufsatz wird ein Vierteljahresmodell der Lohn-
und PreisInflation in Westdeutschland (1964 bis 1978) entwickelt. Es verwendet das Konzept der Phillips-Kurve, betont aber
die überprüfbare Lohndruck-Hypothese und enth?lt die folgenden sechs Variablen: Konsumentenpreise, Effektivl?hne, Streiks,
Tarifl?hne, Nachfrage nach Arbeitskr?ften und die Geldmenge M 1. Mit Hilfe des Konzepts der Wiener-Granger-Kausalit?t und
kürzlich entwickelter Methoden der multivariaten Zeitreihenanalyse entsteht ein empirisches Kausalit?tsmodell der Lohn-Preis-Inflation
für Westdeutschland. Dieses Modell stützt in starkem Ma\e die Lohndruck-Theorie und weist der Geldversorgung eine unbedeutende
Rolle zu. Eine zweiseitige Kausalit?t besteht zwischen den Effektiv- und den Tarifl?hnen, so da\ es unangebracht ist, zeitlich
verteilte Lags anzunehmen für die Tarifl?hne in der Lohngleichung oder umgekehrt für die Effektivl?hne in der Gleichung der
Tarifl?hne. W?hrend sich als Hauptursache der Lohninflation die Inflationserwartungen und die Tarifl?hne identifizieren lassen,
geh?ren zu den wichtigsten Ursachen der Preisinflation die erwarteten Preissteigerungen und die Erh?hung der Kapazit?tsauslastung.
Résumé Causalité et l’inflation de prix et de salaire en Allemagne de l’Ouest 1964–1979. — Dans cet article l’auteur formule un modèle trimestriel de l’inflation de salaire et de prix pour l’Allemagne de l’Ouest sur la période de 1964.1 à 1978.4. Le modèle utilise les éléments fondamentaux de la courbe de Phillips, mais souligne l’hypothèse testable des déterminants de ?wage-push? et consiste de six variables économiques principales: les prix de consommation, les salaires nominaux, les grèves, les salaires contractuels minimum, la demande de la main-d’oeuvre et les disponibilités monétaires (M1). L’auteur applique le concept de causalité de Wiener-Granger aussi bien que des méthodes des séries chronologiques multivariates développées récemment et obtient un modèle empirique de causalité. Le modèle fortement supporte la théorie de ?wage-push? et révèle un r?le insignifiant des disponibilités monétaires. Une causalité deux-voies peut être observée entre les salaires nominaux et les salaires contractuels minimum. Par conséquent, il n’est pas indiqué de spécifier une structure des décalages retards distribués pour les salaires contractuels dans l’équation de salaire ou, qui est équivalent, pour les salaires nominaux dans l’équation de salaires contractuels minimum. Pendant que l’inflation anticipée et les salaires contractuels sont regardés comme les causes principales de l’inflation de salaire les facteurs décisifs de l’inflation de prix incluent les augmentations des prix attendues et l’augmentation de l’utilisation des capacités.
Resumen Causalidad e inflation salarios-precios en Alemania Occidental 1964–1979. — En este artícule se formula un modelo trimestral de inflatión de salarios y precios para Alemania Occidental en el período 1964.1 a 1978.4. Este modelo se basa en la racionalidad de la curva de Phillips pero pone enfasis en la hipótesis comprobable de determinantes de presión de salarios y consiste de seis variables económicas importantes: precios al consumidor, salarios monetarios, huelgas, tasas de salarios mínimos negociados, demanda por trabajo y oferta de dinero M1. Usando el concepto de causalidad Wiener-Granger y métodos de series de tiempo multivariables desarrollados recientemente se obtiene un modelo empérico causal de inflatión salarios precios para Alemania Occidental. Este modelo da fuerte apoyo a la teoría de presión de salarios y revela un papel insignificante para la oferta de dinero. Hay una doble causalidad (o de feedback) presente entre salarios monetarios y tasas salariales minimas negociadas y, tomo tal, la práctica de especificar una estructura de rezago distribuida para estas tasas salariales en la ecuación de salarios, o equivalentemente, para salarios monetarios en la ecuación de tasas salariales mínimas negociadas es inapropiada. Mientras que las principales causas de la inflatión salarial se pueden identificar como inflatión anticipada y tasas salariales mínimas negociadas, las principales causas de la inflatión de precios incluyen aumentos de precios esperados y el aumento de la capacidad utilizada.相似文献

How does international integration affect the welfare state? Does it call for a leaner or an expanded welfare state? International integration may affect the distortions caused by welfare state activities but also the risks motivating social insurance mechanisms. This paper addresses these potentially counteracting effects in a fully specified intertemporal two–country stochastic endowment model, focusing on the implications when product market integration reduces trade frictions across national product markets. It is shown that lower trade frictions may increase the marginal costs of public funds, which gives an argument for reducing (steady–state) public consumption. However, tighter integration of product markets unambiguously leads to more variability in private consumption, and this gives a case for expanding the social insurance provided via state–contingent public sector activities (automatic stabilizers).

This paper discusses the need and scope for an active fiscalstabilization policy. It is argued that the effectiveness offiscal policy as a short run stabilizer does not depend on thelong run multipliers of (balanced budget) fiscal policies. Tothe extent that activity can be affected by aggregate demandin the short run, there is a case for a fiscal stabilizationpolicy in terms of temporary variations in taxes or public consumptioncontingent on the state of the economy. The effectiveness offiscal policy is supported by empirical evidence. However, anappropriate policy intervention depends both on the nature ofthe shock and the structure of the economy. There are thus fundamentalinformation problems in pursuing discretionary fiscal policieson top of political economy concerns, and fiscal fine-tuningis not to be recommended. Automatic stabilizers do not to thesame extent suffer from these problems, but their strength isnot by design but the net result of other policy considerations.Hence, there is a need to consider the structure and size ofautomatic stabilizers.

On the choice of functional form in stochastic frontier modeling 总被引:4,自引:1,他引:4
This paper examines the effect of functional form specification on the estimation of technical efficiency using a panel data
set of 125 olive-growing farms in Greece for the period 1987–93. The generalized quadratic Box-Cox transformation is used
to test the relative performance of alternative, widely used, functional forms and to examine the effect of prior choice on
final efficiency estimates. Other than the functional specifications nested within the Box-Cox transformation, the comparative
analysis includes the minflex Laurent translog and generalized Leontief that possess desirable approximation properties. The
results indicate that technical efficiency measures are very sensitive to the choice of functional specification. Perhaps
most importantly, the choice of functional form affects the identification of the factors affecting individual performance
– the sources of technical inefficiency. The analysis also shows that while specification searches do narrow down the set
of feasible alternatives, the identification of the most appropriate functional specification might not always be (statistically)
feasible.

In this article, we analyze the impact of firms’ technology bases on their financial performance. By taking a strategic perspective of technology, we argue that it is not sufficient to analyze only the size or novelty/quality of the technology base as technology bases can best be understood as portfolios of individual technologies. In such a framework, risk consideration should be taken into account. More specifically, we argue that increasing technological breadth can serve as a hedge against the inherent uncertainties of developing and commercializing technology, in particular when the technology base is very large or novel. We also propose that technology has higher impacts on financial performance for firms with broader technology portfolios. A similar argument proposes that technological breadth can offset the increased risks of addressing foreign markets. We test our hypotheses using an international panel data-set of large R&D-performing firms. Our results suggest that broad technology portfolios can indeed serve as a hedge against technological and commercialization risks. 相似文献
