摘要：
本研究利用政治经济学的价值循环和社会总资本再生产理论，构建了一个理解新发展格局的理论框架，阐述了不同的经济循环模式依赖于技术结构、分配结构、需求结构和生产结构的相互配合，进而通过一个包含固定资本的三大部类再生产模型明确了各种结构的不同组合关系构成了不同类型的发展模式和发展格局。在此基础上，我们利用1957—2017年投入产出表，构建了中国经济的三大部类表，分析了中国经济结构的变化逻辑和由此带来的发展模式变迁路径。此外，还用同样的方法讨论了二战之后美国和日本的结构性特征，以此考察工业化后期可能的发展模式及其变迁规律，为中国未来的经济循环和新发展格局提供必要的启示。

摘要：
this paper considers estimation and inferential issues of panel data models with interactive fixed effects (ife) using diversified projections (dp) method proposed recently by fan and liao (2022). in contrast with ordinary least square method in bai (2009) and weighted least square method in bai and li (2021), our method enjoys some merits such as robustness to the pervasive conditions on factors, stationarity condition on data, or weak serial dependence. under certain regularity conditions, we prove that the dp estimators are root nt-consistent, and have asymptotically normal distribution. we run monte carlo simulations to investigate the finite sample properties of the dp estimators and find its superior performance under the setup alike to real data. we apply our method to the study on the nexus of gdp growth and financial development, and find that the estimate from the dp method is more reasonable than the alternatives in the sense that it is close to the prediction of the related economic theory.

摘要：
we study the effects of the first-ever ratings for corporate securities. in 1909, john moody published a book that partitioned the majority of listed railroad bonds into letter-graded ratings based on his assessments of their credit risk. these ratings had no regulatory implications and were largely explainable using publicly available information. despite this, we find that lower than market-implied ratings caused a rise in secondary market bond yields. using an instrumental-variables design, we show that bonds that were rated experienced a substantial decline in their bid-ask spreads, which is consistent with reduced information asymmetries and improved liquidity. our findings suggest that ratings can improve information transmission, even in settings with the highest monetary stakes, and highlight their potential value for the functioning of financial markets.
