We examine the impact of piped water on the under-1 infant mortality rate (IMR) in Brazil using a recently developed econometric procedure for the estimation of quantile treatment effects with panel data. The provision of piped water in Brazil is highly correlated with other observable and unobservable determinants of IMR — the latter leading to an important source of bias. Instruments for piped water provision are not readily available, and fixed effects to control for time-invariant correlated unobservables are invalid in the simple quantile regression framework. Using the quantile panel data procedure in Chen and Khan [Chen, S., Khan, S., Semiparametric estimation of non-stationary censored panel model data models with time-varying factor. Econometric Theory 2007; forthcoming], our estimates indicate that the provision of piped water reduces infant mortality by significantly more at the higher conditional quantiles of the IMR distribution than at the lower conditional quantiles (except for cases of extreme underdevelopment). These results imply that targeting piped water intervention toward areas in the upper quantiles of the conditional IMR distribution, when accompanied by other basic public health inputs, can achieve significantly greater reductions in infant mortality.  相似文献

In the context of a model due to Robinson, Solow and Srinivasan (the RSS model), we report results on the existence and characterization of locally optimal programs, a concept taken from theoretical physics. In particular, we propose a (new) transversality condition under which all locally optimal programs are good. An extended introduction places our theorems in the context of previous work on the existence question, including that on agreeable programs. It appears that there is no completely rational way to attack [the] problem without considering development programmes over an infinite horizon (Gale in Rev Econ Stud 34:1–8, 1967). The analysis of simple models is essential if we are to understand the corresponding situation for more complex models of the economy (Mirrlees and Stern in J Econ Theory 4:268–288, 1972). The technical convenience, for clear and quantitative results, of using an infinite time horizon is rather great (Hammond and Mirrlees in Models of economic growth, Wiley, New York, pp 283–299, 1973).  相似文献

The fast-food restaurant segment has been a dominant player in the restaurant industry since the 1960s. The recent changes in the needs and wants of guests have affected fast-food restaurants' ability to keep up with the trends regarding healthy and high-quality food options served at reasonable prices. The service quality perceptions assessed in this study were divided into the following constructs: overall experience, employees, ordering process, receiving order, and food quality. The results determined that the construct that influenced repeat intention was food quality, specifically the individual items “fresh food” and “food taste.” The study also found that males tended to evaluate employees more positively than females. Moreover, frequent fast-food diners only tended to have favorable perceptions with regard to the overall ordering process. Implications for practitioners and suggestions for future studies are discussed.  相似文献

Consumers are increasingly concerned about the negative environmental implications of purchasing goods, which in turn shape their behaviour. Yet, there are indications that consumers do not always act on these concerns, causing an attitude–behaviour gap. For consumers to make ecologically responsible purchases, they need relevant product environmental information. Therefore, marketers and firms are increasingly integrating more detailed environmental information in their offerings, including eco-labels with externally validated information. This study integrates consumers’ knowledge and trust in eco-labels with their environmental knowledge to determine how these affect pro-environmental consumer behaviour (PECB). The findings suggest environmental and eco-label knowledge is positively associated with attitudes towards the environment, and that positive environmental attitudes and trust in eco-labels affect PECB. This implies that firms, policy-makers and accreditation organisations (i.e. labelling) can educate consumers about eco-labels and the environment to increase PECB. Such strategies will also build consumer knowledge and trust in eco-labels, necessary for facilitating PECB.  相似文献

This article investigates the out-of-sample forecasting performance of some linear and nonlinear univariate time series models on the monthly seasonally adjusted Canadian unemployment rates during the 1980–2013 period. The findings reveal that nonlinear time series models better capture the asymmetry present in the unemployment rate series at short and long forecast horizons.  相似文献

Zusammenfassung Geld in der Produktionsfunktion: Eine Fallstudie für Frankreich. — Dieser Aufsatz benutzt Daten für Frankreich (1950–1973), um zu prüfen, ob (a) reale Geldbest?nde eine Grenzproduktivit?t haben, die mit der physischer Inputs vergleichbar ist, und ob (b) die Einführung von Geld in die Produktionsfunktion aufgrund einer Vielzahl von Strukturver?nderungen zu einer Instabilit?t der Produktionsbeziehungen führt. Die Autoren ermitteln eine Zeitreihe für das Grenzprodukt des Geldes. Indem sie die Technik zeitlich variierender Parameter in ihrer Regressionsanalyse verwenden, finden sie heraus, da\ die Einführung von Geld in die aggregierte Produktionsfunktion keine Instabilit?t der Produktionsbeziehungen mit sich gebracht hat.
Résumé La monnaie dans la fonction de production: une étude de cas pour la France. — En utilisant les données pour la France, 1950–1973, cet article essaie de tester (a) si les balances de monnaie réelle ont une productivité marginale qui est similaire à celle des inputs physiques, et (b) si l’introduction de la monnaie dans la fonction de production mène à l’instabilité dans les relations de production due à toutes sortes des changements structurels. Les auteurs présentent une série chronologique du produit marginal de monnaie. En utilisant une technique des paramètres variants sur le temps ils trouvent aussi que l’introduction de la monnaie dans une fonction agrégée de production ne mène pas à une instabilité dans les relations de production.

Resumen Dinero en la función de producción: un estudio del caso de Francia. — Usando datos de Francia para el periódo 1958–1973, en este artículo se intenta someter a prueba, (a) si los balances de dinero real tienen una productividad similar a la de insumos fisicos y, (b) si la introducci?n de dinero en la función de producción lleva a una inestabilidad en las relaciones de producción debido a una variedad de cambios estructurales. Los autores presentan una serie temporal del producto marginal del dinero. Usando una técnica de paràmetros variables en el tiempo también descubren que la introducción del dinero en la función de producción agregada no imparte inestabilidad en las relaciones de producción.

Summary In this paper, we report a mode of the Harris-Todaro variety in which the labor force is composed of distinct and easily identifiable ethnic groups and in which capital is intersectorally mobile. We extend the central theorems of Heckscher-Ohlin-Samuelson trade theory to our model and also relate our results to other work.This work was conceived over several visits to The Pakistan Institute of Development Economics and finished at Berkeley where it was first presented at Professor Bardhan's Workshop in Development Economics. I am grateful to Professor Bardhan and to Director Naqvi and other Officers of the Institute for their hospitality and interest. I am also grateful to Naeem Siddiqui and Ray Reizman for several useful conversations; to S. Broca for many provocative comments on the HOS trade model; and, in particular, to one of three anonymous referees for her/his careful reading and detailed comments.  相似文献

It is by now a commonly accepted proposition that economic development must involve both growth and equity. That in many countries the subsidization of the owners of large farms is inequitable is also acknowledged. However, the debate on the ‘efficiency’ of large versus small farms continues. If the owners of large farms are not using the crop acreage with greater efficiency than are the small farmers and if there are no economies of scale, then the imposition of ceilings on farm size and land redistribution are clearly the right options to consider.The object of this study is to test two hypotheses. First, there is an inverse relationship between land productivity and farm size. Second, there are no economies of scale in agricultural production. The tests are performed by regression analysis on the farm-level data collected from Pakistan by the author in 1974. The merit of this study is that it deals with a country which, with a few other underdeveloped countries, has been a beneficiary of the ‘Green Revolution’. The available studies on Pakistan agriculture are limited to the aggregate analyses. Interregional micro-level studies are almost non-existent.  相似文献

Abstract.  Sticky price models based on menu costs predict that countries with high trend inflation should have (i) smaller impact effects of demand shocks on output and (ii) less persistent output fluctuations, relative to low‐trend inflation countries. These predictions are tested, controlling for changes in trend inflation, using a country‐specific approach. The results do not support the second prediction. That prediction is also not robust to a modified measure of trend inflation that excludes episodes of hyperinflation. These findings suggest that while price stickiness is important for understanding short‐run impact effects, real propagation mechanisms may drive persistence in output fluctuations.  相似文献

We show that Quibria's insightful observation on the efficacy of urban policy in a model with an urban trade union and an urban informal sector holds, but with a revenue-neutral employment tax-subsidy combination levied on the urban employer. We also draw the relevance of the generalized Harris–Todaro model in providing intuition for the validity of this surprising result.  相似文献
