浅谈多层房屋顶层常见裂缝的防治

多层砖混结构房屋顶层墙体产生裂缝是普遍存在的质量通病,其危害不可低估:裂缝一般都在建筑外墙装饰装修完工之后显露出来,如果没有一定的技术设备条件很难对其进行修补和控制;裂缝在风吹、日晒、雨淋和其它自然外力作用下不断扩展,将造成外墙渗漏、装饰层破坏脱落,影响建筑物的正常使用功能;裂缝继续扩展,最终对房屋结构产生破坏性影响,缩短使用寿命,给房屋使用者的工作学习及生命财产安全造成严重危害。本文分析了多层砖混结构房屋顶层墙体裂缝的形态及产生机理,给出了防治裂缝的一些有效措施。

Dynamics of floating exchange rate: how important are capital flows relative to macroeconomic fundamentals?

While focusing on traditional macroeconomic fundamentals, existing literature has provided little understanding of impacts of various types of capital flows on the dynamics of floating exchange rates. This paper develops a structural VAR model that takes into account macroeconomic fundamentals as well as various types of capital flows in explaining the fluctuations of the floating exchange rates of the Australian dollar, the Canadian dollar, and the U.S. dollar over 1980–2004. Our main findings are as follows. Among the traditional macroeconomic fundamentals, relative interest rate still plays a significant role in explaining exchange rate dynamics for all three currencies. Capital flows play an important role in explaining the fluctuations in the Australian dollar and the Canadian dollar, but not the U.S. dollar. In particular, portfolio investment is the most explanatory factor for the Australian dollar and the Canadian dollar. For the U.S. dollar, relative interest rate explains the most of exchange rate fluctuations, especially in the medium to the long run. The results indicate that capital market transactions do play important roles in determining exchange rates; however, it may have different implications for the reserve currencies versus the non-reserve currencies. Further research is needed.     

Asymmetric information,adverse selection,and the pricing of CMBS

We demonstrate that asymmetric information between sellers (loan originators) and purchasers (investors and securities issuers) of commercial mortgages gives rise to a standard lemons problem, whereby portfolio lenders use private information to liquidate lower quality loans in commercial mortgage-backed securities (CMBS) markets. Conduit lenders, who originate loans for direct sale into securitization markets, mitigate problems of asymmetric information and adverse selection in loan sales. Our theory provides an explanation for the pricing puzzle observed in CMBS markets, whereby conduit CMBS loans are priced higher than portfolio loans, despite widespread belief that conduit loans are originated at lower quality. Consistent with theoretical predictions of a lemons discount, our empirical analysis of 141 CMBS deals and 16,760 CMBS loans shows that, after controlling for observable determinants of loan pricing, conduit loans enjoyed a 34 basis points pricing advantage over portfolio loans in the CMBS market.

Pension regulation and the market value of pension liabilities: A contingent claims analysis using Parisian options

We analyze the market-consistent valuation of pension liabilities in a contingent claim framework whereby a knock-out barrier feature is applied to capture early regulatory closure of a pension plan. We investigate two cases which we call “immediate closure procedure” and “delayed closure procedure”. In an immediate closure procedure, when the assets value hits the regulatory boundary, the pension plan is terminated immediately. Whereas in a delayed closure procedure, a grace period is given to the pension fund for reorganization and recovery before premature closure is executed. The framework is then used to construct fair pension deals. Furthermore, we provide rules for deriving the optimal recovery period in pension regulation using utility analysis and interconnect the recovery period to the regulatory liquidation probability.
