This network can better capture the complex correlation including non-linearity, periodicity, and time variability among financial institutions and facilitate to find the optimal model by an adjustment parameter. The empirical study concludes that the newly constructed network demonstrates superior performance in identifying systemic importance. Furthermore, the systemic importance of Chinese financial institutions varies across market cycles and conditions. Banks consistently hold higher systemic importance, while insurance institutions show increased sensitivity to economic cycles and the systemic importance of securities firms increases significantly under stable market. Specially, further comparative study about banks means that the character of “too connected to fail\" cannot be ignored and dynamic supervision is indeed necessary. This research offers new perspectives and constructive insights for analyzing the systemic importance of financial institutions. Additionally, the proposed new network model can be applied to assess interdependence in other domains beyond the financial sector.</div></div>","PeriodicalId":47962,"journal":{"name":"Quarterly Review of Economics and Finance","volume":"101 ","pages":"Article 101979"},"PeriodicalIF":2.9,"publicationDate":"2025-03-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143642766","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The framework asserts that, in the long-run, nominal factors do not impact real factors. However, classical macroeconomics has little to say about the composition of productive capital. This has been of less concern to modern economists, but it was of particular concern to pre-Keynesian macroeconomists. Irving Fisher recognized that monetary factors may lead to short-run distortions of relative prices. Despite this recognition, the traditional macroeconomic framework allows for no consideration of persistent relative price distortions. We investigate presentations of macroeconomic theory where such distortions are considered or are at least possible. We leverage the fact that monetary equilibrium does not imply general equilibrium and that transaction costs make reassertion of the initial capital allocation unlikely. We empirically detect persistent distortions in the relative price of oil that suggest that monetary factors generate persistent distortions in capital structure.</div></div>","PeriodicalId":47962,"journal":{"name":"Quarterly Review of Economics and Finance","volume":"101 ","pages":"Article 101978"},"PeriodicalIF":2.9,"publicationDate":"2025-02-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143620202","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

First, the empirical results obtained using the staggered difference-in-differences model indicate that the implementation of the GFRIPZ policy significantly motivates firms to engage in greenwashing behavior. Second, we find that firms under non-state-owned enterprises (non-SOEs) ownership, in non-green industries, and in eastern areas are more likely to engage in greenwashing. Third, our mechanism analysis shows that the GFRIPZ policy stimulates firms’ greenwashing behavior by exacerbating management myopia and promoting public environmental awareness.

First, it unveils the diverse sensitivities of individual cryptocurrencies to total return shocks, with short-term events exerting a predominant influence compared to long-term shocks. Notably, most cryptocurrencies act as net transmitters of shocks, reflecting their susceptibility to external market fluctuations. Second, the variations in the behavior of cryptocurrencies are observed during extreme market conditions and crisis periods, such as the COVID-19 pandemic and the Russia-Ukraine conflict. Furthermore, the outcomes of the portfolio construction process provide light on the efficacy of hedging as well as the performance of the portfolio. Notably, the minimum correlation portfolio (MCP) strategy outperforms other techniques, highlighting its superiority in terms of optimizing portfolio performance. Lastly, we report that macroeconomic factors and asset-based volatility are the significant drivers of cryptocurrency contagion.
