We use regret theory to explain the negative effect of economic animosity on consumers’ reactions towards a foreign product (i.e., product judgment and reluctant to buy). We conduct our study in Taiwan by collecting data via an online survey. Our results show that consumers’ economic animosity increases their anticipated regret towards purchasing a foreign product originating from a target market of animosity. Specifically, anticipated regret is found to mediate the link between economic animosity and foreign product judgment, which in turns affects consumers’ reluctance to buy. Our study is the first to consider the role of anticipated regret in explaining the negative effect of economic animosity on consumers’ reactions towards a foreign product. We also contribute to research by introducing two antecedents of economic animosity: perceived economic competition and consumer ethnocentrism. 相似文献

College students, particularly ethnic minorities in the US, are at a high risk for obesity and health complications. This study determines the type of foods that African-American college students are choosing to eat, and what factors influence those choices. Findings show that fresh fruits, whole grain bread, grilled chicken, and salad top the list of food choices. Knowledge of nutrition labels, gender, weight management, and eating facilities are among the factors found to influence these choices. Managerial implication of findings for the foodservice industry, and other interest groups are discussed. Directions for future research are given. 相似文献

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

This paper provides a bubble date-stamping mechanism using the agent-based computational finance method. The key steps of the bubble date-stamping mechanism are the construction of the simulated financial market, the computation of the characteristic indexes, and the thresholds of the Price Band in the simulated financial market. The present study adopts the mechanism to identify the bubbles of sample stocks in the Chinese stock market from April 2003 to December 2019. The findings show that the bubbles are primarily distributed in 2006–2008, 2009–2012 and 2014–2018, respectively. Furthermore, we analyse the bubble strength and the price fluctuation during the above three periods. In addition to the bubble date-stamping mechanism, the paper also studies the factors that drive the bubbles in the Chinese stock market from both macro and micro perspectives. 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.相似文献

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
