A common problem in applied regression analysis is that covariate values may be missing for some observations but imputed values may be available. This situation generates a trade-off between bias and precision: the complete cases are often disarmingly few, but replacing the missing observations with the imputed values to gain precision may lead to bias. In this paper, we formalize this trade-off by showing that one can augment the regression model with a set of auxiliary variables so as to obtain, under weak assumptions about the imputations, the same unbiased estimator of the parameters of interest as complete-case analysis. Given this augmented model, the bias-precision trade-off may then be tackled by either model reduction procedures or model averaging methods. We illustrate our approach by considering the problem of estimating the relation between income and the body mass index (BMI) using survey data affected by item non-response, where the missing values on the main covariates are filled in by imputations.  相似文献

The present study provides some empirical evidence for the export spillover effect examining the case of an emerging market economy, namely India, using firm level data for the period 1994–2006. We disentangle different spillover channels, namely the demonstration effect, the imitation effect (R&D spillover) and a proxy to measure spillover effects coming from higher MNEs’ skills. We also account for the heterogeneous technological behaviour of local firms considering how in-house R&D efforts and disembodied technological imports may affect the exporting performance. Our findings show how export spillover effects are mainly mediated by an imitation effect, contrary to the case of other emerging market economies like China, where a demonstration effect is evident. We also recognise that both the decision to export and export intensity are influenced most of all by the technological activities of local firms. Moreover, the findings of the analysis suggest that in-house R&D is more relevant than other external sources of technological knowledge such as disembodied technology imports to internalise the positive spillover effect emanating from MNEs.  相似文献

Statement of Financial Accounting Standards No. 109 (SFAS No. 109) allows firms to use their discretion to set arbitrarily high valuation allowances against deferred tax assets. Firms can then later use these "hidden reserves" to manage earnings. Our evidence indicates that most banks do not record a valuation allowance to manage earnings, but rather to follow the guidelines of SFAS No. 109. However, if the bank is sufficiently well capitalized to absorb the current‐period impact on capital, then the amount of the valuation allowance increases with a bank's capital. In later years, bank managers adjust the valuation allowance to smooth earnings. The magnitude of the discretionary adjustment increases with the deviation of unadjusted earnings from the forecast or historical earnings.  相似文献

We analyse the traverse path following either the introduction of a more profitable production technique or a rise in the wage rate on the assumption that investment depends, with a time lag, on the activity level of the economic system. We compare this case with the previously studied cases of an immediate reaction and, the opposite situation, an absence of reaction. We conclude by examining the case in which only some entrepreneurs are innovators.  相似文献

Various facts which belong to the past, present, and future of Italy, which concern both politics and economics, and which are relevant within a broad discussion of monetary policy support the request for a constitutionalization of the target of monetary stability. The authors are grateful to James M. Buchanan for his encouragement in carrying out the research and to an anonymous referee of this journal for his helpful comments on an earlier version of the paper.  相似文献

A Model of Employment in the Arts   总被引:2,自引:0,他引:2  
The behaviour of artists appears to be influenced by non-pecuniary benefits that lead to employment choices inconsistent with traditional expectations of labour supply theory. The paper develops a model of employment in the arts with similarities to the Harris-Todaro model. Seemingly paradoxical results arise. For example, the model illustrates how an increase in wage rates for non-artistic activity may lead to a reduction in the amount of non-artistic activity and a commensurate increase in the amount of time devoted to artistic endeavours. Additionally, the model illustrates how individual work preferences of artists can lead to substantial underemployment in the arts.  相似文献

Zusammenfassung Optimale Nachfragepolitik zur Bek?mpfung der Stagflation. — Der Aufsatz besch?ftigt sich mit der Wahl einer optimalen Gesamtnachfrage-Politik als Antwort auf einen inflation?ren Schock — optimal in dem Sinne, da\ die Volkswirtschaft zur Vollbesch?ftigung und Preisstabilit?t auf einen Pfad zurückgeführt wird, der die sozialen Kosten minimiert. Es wird die Ansicht vertreten, da\ die Kosten eines gegebenen Stabilisierungspfades proportional sind zu den über die Zeit aufsummierten Abweichungen der Inflationsrate und der Arbeitslosenquote von den langfristigen Zielwerten. Auf der Grundlage einer sehr allgemeinen Formulierung der Phillips-Kurve wird die optimale wirtschaftspolitische Antwort auf einen Inflationsschock analysiert und gezeigt, da\ sie gew?hnliche ?Turnpike?-Eigenschaften besitzt. Dieser Ansatz wird veranschaulicht, indem er auf die USA für den Zeitraum 1971–1975 angewandt wird, wobei die Sensitivit?t des optimalen Pfades in bezug auf alternative Wohlfahrts-Bewertungen und Ansichten hinsichtlich der Natur des Trade-off untersucht wird.
Résumé Les politiques de demande optimum contre la stagflation. — Cet article a pour sujet la selection d’une politique de demande agrégée optimum en réponse à un choc — optimum de manière qu’elle reconduit l’économie au plein emploi et à la stabilité de prix le long d’un sentier d’inflation-ch?mage minimisant des frais sociaux de ?welfare?. Nous arguons que les frais du chaque sentier donné de stabilisation peuvent être pris comme proportioneis à l’excès d’inflation et de ch?mage au-dessus du but à long terme, cumulé sur le sentier. En se fiant à une expression très générale de la ?courbe de Phillips? l’article analyse et démontre la réponse de politique optimum à un choc inflationniste pour exhiber des simples ?barrières? propriétés. L’approche est illustrée par l’application sur les E. U. pour la période de 1971 à 1975. Elle explore la sensibilité du sentier optimum aux évaluations alternatives de ?welfare? et aux vues de la nature du ?trade-off?.

Resumen Políticas óptimas de demanda contra la estagflación. — Este artículo se ocupa de la selección de una política de demanda agregada óptima en respuesta a un ?shock? óptimo inflacionario en el sentido que devuelve el pleno empleo y la estabilidad de precios a la economía a través de una trayectoria de inflación-desempleo minimizando los costos sociales de bienestar. Se argumenta que el costo de cualquier trayectoria de estabilización dada puede tomarse como proporcional al exceso de inflación y desempleo por sobre la meta de largo plazo, acumulado a través de la trayectoria. Basándose sobre una formulación muy general de la ?curva de Phillips? se analiza la respuesta de política óptima a un ?shock? inflacionario y se muestra que exhibe propiedades simples de Camino de portazgo. El enfoque se ilustra aplicándolo a los EEUU para el período 1971–75, investigando la sensibilidad de la trayectoria óptima con respecto a evaluaciones de bienestar alternativas y apreciaciones sobre la naturaleza del ?trade-off?.
