Fiscal policy responsiveness, persistence, and discretion 总被引:2,自引:0,他引:2
This paper analyzes the different characteristics of fiscal policy using a two-step estimation procedure. First, we decompose both government spending and government revenue into three components: responsiveness, persistence and discretion. Second, we assess the determinants of these characteristics. Using data from 132 countries, our results show that fiscal policy is more persistent than responsive to economic conditions, which implies that the authorities may have less leeway in the short-run notably to curb spending behavior. In addition, countries characterized by greater fiscal persistence have less discretion and responsiveness. Finally, macroeconomic, institutional and geographic variables explain cross-country variation in fiscal characteristics. 相似文献

In this issue, (Ferguson, C. J., & Donnellan, B. D., Journal of Youth and and Adolescence, published online 21 June 2017) criticize one of our studies (Gabbiadini, A., Riva, P., Andrighetto, L., Volpato, C., & Bushman, B. J., PLoS ONE, 11: 1–14, 2016) that found violent sexist video games can reduce empathy for female violence victims in male players who identify with violent male game characters, and do so by increasing masculine beliefs. Their main criticism is a “straw person” argument built on a claim that we never made (i.e., a direct effect of sexist-violent video games on empathy). They also made several other criticisms of our article. We appreciate the opportunity to respond to their criticisms in this article. We also point out some flaws in their reanalysis. Despite their criticisms, the core contributions of our original article remain intact. 相似文献

We set up an evolutionary game-theoretic model aimed at addressing the issue of local public good provision via direct commitment of voluntary forces (private donors and nonprofit providers) only. Two classes of agents are assumed to strategically interact within a ‘double critical mass’ model and we investigate the critical factors affecting the dynamic outcomes of such interaction. Further, we explore the conditions under which (what we term) ‘evolutionary crowding-out/in’ occurs, depending on agents’ degree of opportunism, social comparison and positive selective incentives (such as subsidies given by the government to ‘virtuous’ citizens or nonprofits only). 相似文献

This study provides regression equations for estimation of age of infants from the dimensions of their developing deciduous teeth. The sample comprises 97 individuals of known sex and age (62 boys, 35 girls), aged between 2 days and 1,081 days. The age‐estimation equations were obtained for the sexes combined, as well as for each sex separately, thus including “sex” as an independent variable. The values of the correlations and determination coefficients obtained for each regression equation indicate good fits for most of the equations obtained. The “sex” factor was statistically significant when included as an independent variable in seven of the regression equations. However, the “sex” factor provided an advantage for age estimation in only three of the equations, compared to those that did not include “sex” as a factor. These data suggest that the ages of infants can be accurately estimated from measurements of their developing deciduous teeth. 相似文献

Childhood disruptive behaviors can be precursors to later deviance. To verify the efficacy of karate, a complex psychomotor activity that enhances self-regulation and executive skills, as an intervention for externalizing behaviors, 16 children, ranging in age from 8 to 10 years, and meeting diagnostic criteria for oppositional defiant disorder were studied. Eight were randomly assigned to a 10-month Wa Do Ryu karate program, whereas 8 children received no intervention. The children were assigned to a larger karate class, composed of typically developing youngsters. Three domains of temperament--intensity, adaptability, and mood regulation--were measured at the beginning and the end of the training period in all 16 participants. A significant improvement in temperament scale scores was measured in the karate group for all tested items compared to controls. Karate, when properly taught, can be a useful adjunct in multimodal programs aimed at externalizing behavior reduction. 相似文献

Abstract In the course of a trial, the main task that every judge or juror has to face concerns the evaluation of various pieces of evidence from a variety of different sources, with the aim of integrating such data into a single, final verdict. Algebraic models have tried to explain and predict decisional paths by identifying formal, mathematical combinatory rules. The aim of the present research was to test two main integration information models, namely adding and averaging, when combining items of judicial evidence. In the first study, we investigated how the probability of guilt varied as a function of the value of the pieces of evidence and information presented, in legal and not legal professional samples. In the second study, we analysed combinatory rules with more complex and realistic experimental material. Results indicated that participants summed the values of pieces of evidence in a linear fashion when they had to provide estimates of guilt. We found evidence of an adding rule among both legal and not legal professionals as well as in simple and more complex judicial cases, thus providing even stronger support for the use and the generalization of a summative model. Theoretical and practical implications are discussed. 相似文献
