We found that “8.11” exchange reform significantly affects the interactions in CNY, CNH and CNH-Hibor three markets. The two-way CNY-to-CNH return spillovers became one-way and in the opposite direction after the reform. The Granger causality test shows price-guide impacts in pairs of CNY, CNH and CNH-Hibor were significantly different after the “8.11” reform. The pricing power of RMB spot exchange rate has been passed from onshore market to offshore market. Meanwhile, the unidirectional volatility spillover from CNH to CNY has changed to bidirectional volatility spillover between CNH and CNY markets. Meanwhile, after the “8.11” reform, the fluctuation of CNH-Hibor impacts the volatility of onshore and offshore exchange rates significantly, CNH-Hibor played a leading role in onshore-offshore foreign exchange and offshore money market interactions. These results are critical for Chinese policymakers and contribute to China’s foreign exchange rate reform.","PeriodicalId":45226,"journal":{"name":"Quantitative Finance and Economics","volume":null,"pages":null},"PeriodicalIF":5.3,"publicationDate":"2020-04-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41461829","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Private Pension System (PPS) helps individuals make savings and contribute to the nation’s economy. Therefore, it is important to know the performance of Private Pension Companies (PPCs) that manage the pension funds. Data Envelopment Analysis (DEA) is one of the useful nonparametric techniques to measure the relative efficiency of Decisions Making Units (DMUs) for a specific time or process. In this study, relative efficiency scores of PPCs are investigated for a time interval with Dynamic DEA and compared with the traditional DEA. Inputs of the model are considered as the number of workers, total assets; and the outputs of the model are the number of contracts, total contribution and the market share of each PPC. Also, to ensure the dynamic procedure, Shareholders’ Equity is used as a quasi-fixed input data to link consecutive periods in the time interval. Our results demonstrate that the efficiency score can be improved by considering the effects of the inter-relations of the consecutive periods. The implications arising from the results of the study are important for the companies’ policies.","PeriodicalId":45226,"journal":{"name":"Quantitative Finance and Economics","volume":null,"pages":null},"PeriodicalIF":5.3,"publicationDate":"2020-03-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"70228779","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Tokens are immediately transferable and can be traded 24/7 on secondary markets, clearing and settlement is a matter of only a few minutes, tokens can be held personally, i.e. brokers and custody accounts are no longer required and the underlying blockchain ensures transparency of all transactions. This study provides an overview of security tokens and the STO model for corporate financing. Our analysis investigates security tokens from the perspective of a firm looking to raise capital. Building on signaling theory, this paper examines 1) whether companies conducting an STO make use of cheap signals to influence investment behavior and 2) if such use of cheap signals is effective. We analyze a dataset of 151 STOs and identify that cheap signals of human capital and social media are used by projects and have a positive effect on funding success. The type of signals influencing funding success indicate that the market is still immature, as projects have a clear incentive to enlarge the level of asymmetric information between them and potential investors. The anticipated level of punishment for misusing cheap signaling is low, as the mechanism does not represent fraud but \"cheating\". This is a concern for investor protection.","PeriodicalId":45226,"journal":{"name":"Quantitative Finance and Economics","volume":null,"pages":null},"PeriodicalIF":5.3,"publicationDate":"2020-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138503658","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Therefore, the study focuses on the year 2020 which includes before Covid-19 and Covid-19 pandemic times periods. In this context, daily data between 12.06.2019 and 06.16.2020, 6 independent variables, and 6 Covid-19 situations are analyzed by employing Multivariate Adaptive Regression Splines (MARS) method. The findings reveal that (i) influential factors on Turkey’s CDS spreads are BIST100 index, VIX index, MSCI Turkey index, and USD/TL foreign exchange rates for the period which is before Covid-19 pandemic times; (ii) MSCI emerging market index, number of new deaths from Covid-19, USD/TL foreign exchange rates, weighted average cost of funds, number of new cases from Covid-19, and VIX index have effect on Turkey’s CDS spreads in Covid-19 pandemic times, respectively; (iii) on the other hand, number of cumulative cases, number of cumulative deaths, and measures do not have effect on Turkey’s CDS spreads in any period. Taking precautions to decrease negative effects on Turkey’s CDS spreads by considering the importance of deaths number from Covid-19 pandemic is very important. Hence, Turkey could stimulate foreign portfolio investment inflows with decreasing CDS spreads.","PeriodicalId":45226,"journal":{"name":"Quantitative Finance and Economics","volume":null,"pages":null},"PeriodicalIF":5.3,"publicationDate":"2020-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138503669","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

For the full sample, the measures of spectral coherence and gain spectrum suggest a one-to-one relationship, and the frequency domain decomposition of the Granger causality test indicates a bidirectional predictive relationship between the two variables at zero frequency. As suggested by the wavelet coherence, we also analyzed the two subperiods before and after 2006 separately. Our results suggest that while both variables have predictive power for each other in the second subperiod, only money growth helps predict inflation in the first one. In order to prevent spurious results, the analysis is rerun in a multivariate Vector Autoregression (VAR) system, where output growth, interest rate, exchange rate growth, and domestic debt growth are included as additional variables. We observe that while money growth has predictive power for inflation in the first subperiod, this relationship disappears in the second one. We argue that the change in the relationship between the two variables at low frequencies after 2006 is primarily a result of the decrease in fiscal dominance of the government, the CBRT’s switch to the inflation targeting regime, and the CBRT’s “unconventional monetary policy framework”.","PeriodicalId":45226,"journal":{"name":"Quantitative Finance and Economics","volume":null,"pages":null},"PeriodicalIF":5.3,"publicationDate":"2020-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138503670","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Our empirical analysis revealed the following key findings: First, the study revealed that banking system z-scores has positive effect on economic sustainability of developing economies while banking system regulatory capital and bank credit have negative effects on economic sustainability among selected developing economies. Second, while banking system z-scores, bank liquid assets and bank credit have positive effects on economic sustainability of BRICS economies, bank liquid assets and bank credit have negative effects on economic sustainability of non-BRICS economies except banking system zscores, which has a positive effect. In addition, banking system z-scores has positive effect on economic sustainability of Asian and non-Asian economies. However, non-performing loans and bank credit has negative effects on economic sustainability of Asian economies while banking system regulatory capital has negative effect on economic sustainability of non-Asian economies. We conclude that banking system stability play a role in economic sustainability developing economies. However, banking system stability has differing effects on economic sustainability of BRICS and non-BRICS economies; and Asian and non-Asian economies.","PeriodicalId":45226,"journal":{"name":"Quantitative Finance and Economics","volume":null,"pages":null},"PeriodicalIF":5.3,"publicationDate":"2019-11-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46175342","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
