Hungary's entry into the euro area: Lessons for prospective members from a monetary policy perspective

This paper evaluates the conduct of monetary policy in Hungary using standard Taylor rules as well as extended rules that incorporate real exchange rate effects. Moreover, we explicitly consider the impact of future euro area entry by estimating instrument rules that permit an influence from Maastricht Treaty inflation requirements via the estimation of Markov switching models as well as by estimating a differential rule vis-à-vis the existing euro area. Lastly, the paper also considers the impact on policy rules from the large data revision that affects real exchange rate and output estimates. I find that interest rate setting behavior in Hungary does not resemble that of the euro area. Also, counterfactual experiments reveal that the potential macroeconomic costs of entry into the euro area sooner rather than later may be lower than if membership in the single currency area is delayed beyond 2008.     

试论房屋建筑中砖砌体施工技术

随着我国经济的发展,建筑物种类趋于多样化,并取得了显著的成绩。尤其是砖砌体工程其属于房尾建筑中的不可或缺的组成部分,其工程质量好坏将会决定建筑物的整体功能和施工质量。而在房屋建筑砖砌体施工过程中,要做好各个环节的施工准备工作,保证各个环节施工的顺利进行。因此,需要深入研究砖砌体施工技术,采取各种有效手段提高砖砌体施工技术水平。但是我国大部分建筑中的砖砌体施工缺乏统一的标准,从而出现了一系列的安全隐患,因此需要完善砖砌体施工的标准,以确保其施工的标准化、合理化和系统化,提高施工整体质量。本文将对房屋建筑中砖砌体施工技术进行分析。     

From a System of National Accounts to a Process of National Wellbeing Accounting

There are repeated calls to go ‘Beyond GDP’, for measures of wellbeing and progress in addition to those that the System of National Accounts (SNA) is designed to provide. We identify key issues that can help build on the rigour of SNA whilst fitting the measurement of economic performance within a broader assessment of national wellbeing and progress. Such drivers are already leading to a proliferation of indicators and accounts, for example in the development of non‐monetary measures of natural resources, but there are significant measurement challenges, not least the question of whether a single, overall measure or index of wellbeing is valid. But the challenge of measurement, per se, is one thing: in our view, a more critical issue is whether the measures will actually be used. We propose a dynamic and multi‐staged approach for developing SNA, embracing the production and use of measures. This would start by identifying user requirements for wider measures, to provide the basis for national and cross‐national developments in well‐being accounting. We envisage greater branding and marketing of national well‐being concepts to promote measures and support their use. We call for outreach by producers, so that there is dialogue about the development and use of measures.

Proposal for calculating regulatory capital requirements for reverse mortgages

In the current context in which many people worry about the sustainability of pension systems, reverse mortgages are gaining popularity because they are a way to supplement elderly people's incomes. However, it is necessary to provide banks with an adequate risk measurement and management procedure for reverse mortgages to increase the commercialization of these products, which will result in greater well-being for the retirement age population. In this paper, we propose a method to measure risk and estimate the regulatory capital requirements for a portfolio of reverse mortgages owned by a financial institution according to Basel II and III. The method considers house price risk, mortality risk and interest rate risk; consequently, regulatory capital requirements need to be computed using a Monte Carlo simulation procedure. The proposed method is general and can accommodate several scenarios for reverse mortgage specifications, including fixed or variable mortgage rates and different income stream schemes (with the lump sum as a particular case). The results for the U.K. show that reverse mortgage providers face higher risk when the lender initially advances a higher amount, with the lump-sum case indicating the highest risk, for relatively younger borrowers, the female population, higher interest rates and floating mortgage rates.     

Interactive information disclosure and non-penalty regulatory review risk

Using monthly data from the Shenzhen Stock Exchange's ‘Hudongyi’ platform and comment letters from December 2014 to December 2018, this study investigates the influence of interactive information disclosure on non-penalty regulatory review risk. The findings reveal that the richness and activeness of interactive information disclosure are positively associated with regulatory review risk. Moreover, the non-penalty regulatory review is effective as it significantly reduces the probability of receiving a comment letter in the subsequent three periods. The timeliness of interactive information disclosure is negatively associated with regulatory review risks. Additionally, we find that newspaper media coverage partially mediates the relationship between interactive information disclosure and regulatory review risk. For companies with low levels of internal governance, in low-competitive industries, and state-owned companies, the positive relationship between the number of investor questions and regulatory review risk is strengthened. These findings enrich the literature on the determinants of regulatory review risk and the economic consequences of interactive information disclosure in emerging markets.

External Constraint and Financial Crises with Balance Sheet Effects

This article investigates the dynamic implications of Krugman's (1999 Krugman, P. 1999. Balance sheets, the transfer problem, and financial crises. International Tax and Public Finance, 6(4): 459–472. (doi:10.1023/A:1008741113074)[Crossref], [Web of Science ®] , [Google Scholar]) model of financial crises with balance-sheet effects, which has a considerable impact on the literature of international financial crisis. Considering explicitly the wealth-accumulation constraint and the external equilibrium condition, I describe an emerging-market financial crisis as a jump from an unstable dynamic trajectory to a stable one, instead of a jump from a ‘good’ to a ‘bad’ equilibrium with zero investment and zero foreign debt. By discriminating the financial crises according to the severity of the negative impacts of some internal and external factors, this article also adds some insights into the anti-crisis policy.
