中国企业税负高低之谜:寻找合理的企业税负衡量标准

作者梳理了企业税负衡量标准的相关文献,运用微观经济学中的"死角损失"原理,观测中国近年来的广义宏观税费负担,发现其依然处于偏高的水平上。尤其对于贡献绝大部分税费的企业来说,整体税负过重的倾向并无根本改观,其中非公经济的税负更是连年超过国有企业。在对企业税负的衡量中,作者采用了世界银行的总税率指标进行国际比较,同时在对企业实际税费负担的计算中以上市及非上市公司为代表,测算了企业销售利润率与税利率之间的变动关系,进而阐述中国税制所存在的问题,据此提出针对性较强的政策建议。     

中国和东盟人民币贸易结算的经济学分析

本文构建了一个三经济体的贸易模型,从贸易损失的角度分析中国和东盟地区采用人民币进行贸易结算对中国和东盟,以及对世界其他主要经济体的福利影响。分析结果表明:中国和东盟地区结成货币联盟对世界主要经济体都将产生正面效应;由于东盟地区整体技术稍低,中国和东盟结成货币联盟将使东盟贸易损失下降更多和产出增加更大,从而提升东盟地区的整体福利;中国和东盟进行人民币结算对各经济体而言,属于帕累托改进,符合激励相容原则,具备理论上的可行性;中国和东盟进行货币联盟的优势在于两大经济体之间的地缘优势和生产技术类似。     

西部大开发战略与税制改革

1994年税制改革形成的现行税制基本格局,存在税收与税源不一致的重大缺陷,造成西部地区和地方税收分配比例过低,而东部地区和中央税收分配比例过高。深化西部大开发战略,必须深化税制改革,逐步贯彻税收与税源一致性原则,优化税收分配格局,大幅提高西部地区地方财力。此外,从税收体现的经济联系看,目前“西三角”作为经济实体还难以形成。     

An Empirical Analysis of the Extreme Cherry Picking Behavior of Consumers in the Frequently Purchased Goods Market

Extreme cherry pickers are customers who seek price deals and excessively avail themselves of deep discount offers, which generates negative profits for retailers. This study uses market transaction and primary consumer survey data to provide insights into the determinants, prevalence, and profit impacts of such behavior in the frequently purchased goods market. We find that the extreme cherry picking segment is small (about 2% of all shoppers), but its relative value varies across stores, and consumers manifest this behavior only in secondary stores. An inverse U-shaped relationship marks consumers’ opportunity costs for cross-store price search and likelihood of extreme cherry picking behavior. Finally, we also find that a loss leader promotional strategy adds to retailers’ bottom lines, despite the pure loss generated by extreme cherry pickers.     

Loss given default models incorporating macroeconomic variables for credit cards

Based on UK data for major retail credit cards, we build several models of Loss Given Default based on account level data, including Tobit, a decision tree model, a Beta and fractional logit transformation. We find that Ordinary Least Squares models with macroeconomic variables perform best for forecasting Loss Given Default at the account and portfolio levels on independent hold-out data sets. The inclusion of macroeconomic conditions in the model is important, since it provides a means to model Loss Given Default in downturn conditions, as required by Basel II, and enables stress testing. We find that bank interest rates and the unemployment level significantly affect LGD.     

Evaluation periods and asset prices: Myopic loss aversion at the financial marketplace

Examining myopic loss aversion (MLA [Benartzi, S., Thaler, R., 1995. Myopic loss aversion and the equity premium puzzle. Quarterly Journal of Economics 110, 73–92]) in real financial markets has several merits: in repeated situations investors may learn from each other, aggregate market prices may eliminate individual violations of expected utility, and individuals may decide differently in real situations than in laboratories. We utilize a special feature at the Tel Aviv stock exchange (TASE): occasional shifts of securities from daily to weekly trading. If investors’ decisions are influenced by trading frequency manipulation, then returns should be predictably affected. MLA results in a negative relation between risk aversion and the length of the evaluation period. Thus, the longer the evaluation period is, the lower the expected return is. This intuition also suggests reduced sensitivity to economic events in longer evaluation periods. We find strong support for MLA in the marketplace when testing expected return, as well as return sensitivity.     

对加强长三角产业协调发展法制建设的思考

近几年来，长三角以产业协调发展为核心的区域经济一体化趋势正在形成，客观上需要我们在长三角产业协调发展管理、效益评估和质量互认、合作与竞争、金融保障、环境保护、经济监督等方面加强法制建设，这对于依法引导、规范和保障长三角产业协调发展，实现长三角区域合作与发展战略目标，都具有重要的现实意义。     

Inter-temporal choices with temporal reference dependence

I develop an intertemporal choice model for rational deviators whose preferences depend not only on their actual consumption but also on comparison to their beliefs about the optimal consumption. The standard decision maker is loss averse with respect to this belief-dependent reference point. When psychologically weighted loss aversion is low, a decision maker deviates from the standard intertemporal choice behavior and over-consumption, as well as the alternative possibility of under-consumption can be rationalized. When the decision maker has time-varying degrees of loss aversion, he re-optimizes the consumption plan through adjusted beliefs as subsequent selves realize that past decision for the present period is no longer optimal. In the dynamic model, I solve for consistent intertemporal optimization rules by which a dynamic deviator should meet rational intertemporal consistency at each point in time. Finally, I demonstrate that the dynamic reference dependent model can solve a puzzling feature in lifecycle consumption data.     

金融稳定是否应纳入中国货币政策目标——基于混频IS-Phillips模型的实证分析

文章首先使用混频动态因子模型（MF-DFM），构建中国首个混频金融稳定指数（MF-FSI），接着把MF-FSI作为金融稳定的代理变量，使用文章新构建的混频IS-Phillips模型，比较分析纳入与不纳入金融稳定的中国货币政策损失函数差异，最后对货币政策目标选择和时效选择进行了敏感性分析，实证分析表明：（1）中国混频金融稳定指数是金融稳定的一个实时性有效测度指标；（2）中国货币政策目标应纳入金融稳定，以减少货币政策福利损失；（3）无论中国货币政策目标偏好和预期偏好怎样变化，央行都应给予金融稳定固定且不可忽略的关注度，但物价稳定和经济增长仍为主要货币政策目标。
