This paper compares the empirical performance of the realized volatility estimators on an extensive high-frequency dataset of stock indices from four developed European markets with thick trading and intensive intraday activity. Even though the proposed estimators have distinctive properties, it is not clear which one has a better performance in terms of unbiasedness and consistency. Some of them are robust to microstructure noise only, and others are robust solely to price jumps, whereas a few of them are robust to both. Therefore, the main purpose is finding a benchmark estimator among alternative competitors, as the best proxy of integrated variance, and empirical demonstration of its superiority. The vast majority of the existing studies largely rely on developed US data or simulation data, but inferences obtained on such data might deviate from European developed markets. This study aims to fill in that niche. In particular, the optimal sampling frequency of proposed benchmark estimator is determined with respect to the trade-off between its bias and the variance of each stock index individually. Afterwards, probability integral transformation, Mincer–Zarnowitz regression and upper tail correlation from appropriate copula function are considered as an adequate pairwise comparison methods. Notable contributions of this paper include unambiguously proven superiority of robust two times scaled estimator for selected European developed markets within the range of optimal slow time frequency from 10 to 30 s. Finally, recommendations for research and practitioners regarding the usage of jump robust two times scaled estimator are given. In fact, asset managers, institutional investors as well as market regulators could benefit from proposed realized volatility benchmark in making long-term investment decisions, leading to sustainable finance.
Fiscal councils are independent institutions that play an important role in execution of fiscal rules and budgetary discipline through their realistic and unbiased macroeconomic and budgetary analysis and projections. It is important that the fiscal councils have easy access to the media to ensure that their analyses reach the wider public, and influence creators of fiscal policy. This paper analyzes the influence of fiscal councils on budget balance and public debt in period before and after financial crisis. The member states that had functioning fiscal councils before the financial crisis, on average, manage their public finances better than those who founded them after the beginning of crisis. Additionally, supervision of the enforcements of fiscal rules from fiscal boards is already showing positive results in this short time period. Fiscal councils are extremely important to ensure a healthy basis for conducting fiscal policy and to decrease the influence of politics on public finance management.
Sustainable investments make a growing and important share of total assets under management in the fund management industry. Except for investor preferences, a significant driver of demand for sustainable assets will also be the new European plan for sustainable finance. The goal of the plan is to reorient capital towards a more sustainable economy by incentivizing financial intermediaries to offer more sustainable investment products. This paper aims to assess the EU plan for sustainable finance and explain its implications on the financial system and the economy of a small member state, using Croatia as an example. In addition to that, we also present policy advice for policymakers that want to use the European plan for sustainable finance to make their economy (more) sustainable. We find that although the plan is broad and ambitious, to ensure its overall success some additions and tweaks at the national level could be needed. First, including pension plans as one of the biggest investors in many EU member states would increase overall plan impact. Second, national-level regulation about non-financial (sustainability) data for listed companies might be beneficial. Without such regulation, obtaining data directly from corporations might result in non-comparable reports or missing data. In the second step, this could undermine the plan's overall goals.
Crisis management in the context of public institutions is particularly important, due to the extremely large possible impact of the consequences of systemic crises on society as a whole. Suboptimal or too slow decisions of public institutions usually affect a much wider set of people, entities, and economic and financial developments than when it comes to crisis management in individual companies, even if they are systemically important. This paper focuses on the activities of the Croatian National Bank and the Croatian Financial Services Supervisory Agency in dealing with the crisis caused by the coronavirus pandemic and presents the most important activities of the government, government agencies, and commercial banks that have had an impact on financial stability. The analytical part of the paper presents the effect of trading suspension on the Zagreb Stock Exchange on 12th March 2020 and its implications on the market. Although it is still too early to make final assessments, given the course of the pandemic, the available data suggest that the activities of domestic institutions have so far been effective in maintaining financial stability in Croatia.
