Most empirical studies of real gross domestic product (GDP) growth rates exclude the dimension of conditional volatility shocks. In this paper, we search for evidence of conditional volatility in the quarterly real GDP of greater China, which comprises the economies of Mainland China, the Hong Kong Special Administrative Region (SAR), and Taiwan. The widely accepted exponential GARCH model of Nelson [Econometrica 59 (1991) 347–370] is employed to capture the possible existence of asymmetric conditional volatility in real GDP. It is found that negative real GDP shocks may induce a greater impact on future volatilities compared with positive shocks of the same magnitude. Policy implications from our findings are discussed. 相似文献

This paper reexamines the welfare effects of illegal immigration studied by Hazari and Sgro [The simple analytics of optimal growth with illegal migrants. Journal of Economic Dynamics and Control 28(1) 141–151]. In contrast to their negative conclusion, we obtain ambiguous welfare prediction which is due to the presence of two opposing effects at work: a positive exploitation effect and a negative intertemporal effect. With Cobb–Douglas production technology, we show that per capita domestic consumption rises in the presence of illegal migration. 相似文献

This article compares the long-run effects of changes in health conditions, population growth, price of medical care, and Medicare indemnity rate on capital formation and medical expenditures under fully funded and pay-as-you-go Medicare. Surprisingly, it is found that population growth, rising medical prices, and increasingly adverse health conditions may or may not raise medical expenditures in the long run. Moreover, the directions of some of these effects under the pay-as-you-go Medicare system are reversed under the fully funded system. Finally, it is shown that fully funded Medicare results in higher steady-state capital than pay-as-you-go Medicare; however, the welfare effect of the former may or may not be higher than that of the latter in general.

Global account management--which treats a multinational customer's operations as one integrated account, with coherent terms for pricing, product specifications, and service--has proliferated over the past decade. Yet according to the authors' research, only about a third of the suppliers that have offered GAM are pleased with the results. The unhappy majority may be suffering from confusion about when, how, and to whom to provide it. Yip, the director of research and innovation at Capgemini, and Bink, the head of marketing communications at Uxbridge College, have found that GAM can improve customer satisfaction by 20% or more and can raise both profits and revenues by at least 15% within just a few years of its introduction. They provide guidelines to help companies achieve similar results. The first steps are determining whether your products or services are appropriate for GAM, whether your customers want such a program, whether those customers are crucial to your strategy, and how GAM might affect your competitive advantage. If moving forward makes sense, the authors' exhibit, "A Scorecard for Selecting Global Accounts," can help you target the right customers. The final step is deciding which of three basic forms to offer: coordination GAM (in which national operations remain relatively strong), control GAM (in which the global operation and the national operations are fairly balanced), and separate GAM (in which a new business unit has total responsibility for global accounts). Given the difficulty and expense of providing multiple varieties, the vast majority of companies should initially customize just one---and they should be careful not to start with a choice that is too ambitious for either themselves or their customers to handle. 相似文献

Balanced‐budget rules and aggregate instability: The role of consumption taxes in a monetary economy
In a real macroeconomic model, it is well established that a balanced‐budget rule based on consumption tax can rule out indeterminacy. The present paper shows, both analytically and numerically, that such a balanced‐budget rule induces indeterminacy and, hence, aggregate instability in a standard one‐sector cash‐in‐advance economy. From a policy perspective, our results raise possible concerns that balanced‐budget rules with endogenous consumption tax could have destabilizing effects under the current over‐easy monetary environment. 相似文献

AbstractThis article accounts for the logic of building of an accountability mechanism with elements of civic engagement in an authoritarian regime. It is elaborated by a performance evaluation programme ‘Democratic Review of Administrative and Business Style’ (DRABS) in Wuhan in central China. The author argues that the DRABS does help form government agencies’ responsiveness to the public with various public scrutiny instruments including mass media and the internet, and that it is more accurate to frame the mechanism as having the function of building horizontal accountability to enhance vertical accountability. 相似文献

In a controlled laboratory experiment, we found evidence for our predictions that participants who received fair distributive
treatment were more likely to lie to give a supervisor a good performance evaluation than those treated unfairly, and those
who received unfair distributive treatment were more likely to steal money from a supervisor than those treated fairly. We
further proposed that the presence of an ethical code of conduct would moderate these relationships such that when the code
was present these relationships would be weaker than when the code was absent, but we failed to find support for these moderating
effects. Our findings suggest that the relationship between distributive justice and unethical behavior is likely more complex
than previously considered. Both researchers and managers may benefit from a broader understanding of the factors that motivate
and inhibit unethical behaviors intended to benefit and harm supervisors and/or organizations. 相似文献

This paper examines the relationship between option trading activity and stock market volatility. Although the option market is uniquely suited for trading on volatility information, there is little analysis on how trading activity in this market is linked to stock price volatility. The bulk of the discussion tends to focus on whether trading activity in the stock market is informative about stock volatility. To analyze the information in option trading activity for stock market volatility, a sample of 15 stocks with the highest option trading volume is selected. For each stock, it is noted that the trading activities in the put and call option markets have significant explanatory power for stock market volatility. In addition, the results indicate that the call option trading activity has a stronger impact on stock volatility compared with that of the put options. Our results demonstrate that information and sentiment in the option market is useful for the estimation of stock market volatility. Also, the significance of the effects of option trading activity on stock price volatility is observed to be comparable to that of stock market trading activity. Furthermore, the persistence and asymmetric effects in the volatility of some stocks tend to disappear once option trading activity is taken into account. 相似文献

ABSTRACTAt the beginning of 2013, a Beijing non-profit group launched a ‘Clean Your Plate Campaign’ on Sina Weibo, a Chinese Twitter-like microblogging site, with aims to reduce food waste. This paper examines social media users’ reactions during two periods of the first three years of the campaign. Upon examination of topic content, supporting participation was the most popular topic in January 2013 and showcasing individual achievement was the most frequently discussed topic in March 2016, with socialising as the common purpose for posting in both months. Users mentioning the campaign most in January 2013 belonged to private organisations, with posts from ordinary people becoming more predominant by March 2016. This study sheds light on the use of social media to raise public awareness regarding food waste in China. The findings will help campaigns aiming to promote food waste reductions or other social movements that use social media as a platform for citizen involvement. 相似文献

Valuing the Willingness‐to‐Pay for Sustainable Seafood: Integrated Multitrophic versus Closed Containment Aquaculture 下载免费PDF全文
Winnie Yip Duncan Knowler Wolfgang Haider Ryan Trenholm 《Revue canadienne d'agroeconomie》2017,65(1):93-117
Awareness of the environmental problems associated with conventional finfish aquaculture has stimulated interest in more sustainable production methods. For example, integrated multitrophic aquaculture (IMTA) combines the culturing of fish and extractive aquaculture species at one site to simulate a balanced natural system. In contrast, closed containment aquaculture (CCA) separates farming from the natural marine environment using closed water tanks on land or in water. We explore consumer preferences for salmon produced with IMTA or CCA rather than conventional technology and pose two questions: how aware of IMTA and CCA are salmon consumers on the U.S. West Coast and what are they willing to pay for salmon produced with these methods? Using a discrete choice experiment, we estimate marginal willingness‐to‐pay of 39.0% and 15.7% for IMTA and CCA, respectively, as a premium added to the price of conventionally farmed Atlantic salmon. Results using latent class analysis show that consumers with a strong preference for wild salmon have high marginal values for farmed salmon produced with IMTA or CCA, but the average consumer from this group would be unlikely to purchase it. Overall, 44.3% and 16.2% of the respondents preferred IMTA or CCA to conventional salmon farming, respectively, and IMTA was preferred to CCA when respondents were asked to choose one. La sensibilisation aux problèmes environnementaux liés à l’élevage de poissons classique suscite un intérêt pour des méthodes de production plus durables. Par exemple, l'aquaculture multitrophique intégrée (AMTI) combine l’élevage de poissons et d'espèces d'extraction sur un même site afin d'imiter un écosystème naturel équilibré. En revanche, l'aquaculture en parc clos (APC) consiste en un élevage hors du milieu marin naturel à l'aide de réservoirs étanches installés sur le sol ou dans l'eau. Dans la présente étude, nous avons analysé les préférences des consommateurs pour le saumon issu de l'AMTI ou de l'APC et celui issu de l’élevage classique. Nous nous sommes également posé deux questions : À quel point les consommateurs de saumon de la côte Ouest des États‐Unis connaissent‐ils l'AMTI et l'APC, et combien sont‐ils prêts à payer pour obtenir du saumon issu de ces méthodes de production? À l'aide de la méthode des choix discrets, nous avons obtenu un consentement à payer marginal de 39,0 % pour l'AMTI et de 15,7 % pour l'APC, de plus que le prix du saumon de l'Atlantique issu de l’élevage classique. Les résultats de l'analyse des classes latentes ont montré que les consommateurs qui affichaient une préférence marquée pour le saumon sauvage avaient des valeurs marginales élevées pour le saumon issu de l'AMTI ou de l'APC, mais qu'il était peu probable que le consommateur moyen de ce groupe en achète. Dans l'ensemble, les répondants ont indiqué préférer le saumon issu de l'AMTI ou de l'APC (44,3 % et 16,3 % respectivement) au saumon issu de l’élevage classique. De plus, s'ils avaient à choisir entre le saumon issu de l'AMTI ou de l'APC, ils choisiraient le saumon issu de l'AMTI. 相似文献
