Mini‐blasting for repair work

High chloride content of the concrete had led to corrosion of reinforcement in the brackets supporting the access balconies of a block of flats in Copenhagen; also affected were parts of the balcony decks and some wall panels. Widespread replacement of the suspect components was chosen, including re‐casting of the support brackets in situ. How the old concrete of the brackets was removed by controlled local blasting is described by a member of Demex consulting engineers, who acted as explosive demolition consultants to this project.

Trends in prices to commercial energy consumers in the competitive Texas electricity market

To date, the price of electricity to commercial or business energy consumers has generally increased at greater rates in the areas of Texas where retail competition has been introduced than in areas that do not enjoy competition. Trends in commercial competitive prices have largely mirrored trends in residential prices. Market restructuring has tended to increase the sensitivity of retail electricity prices to changes in the price of natural gas, the marginal fuel used for generation in Texas. Consequently, the rapid increases in the commodity price of natural gas following restructuring led to increases in competitive electric rates which exceeded the increases in areas not exposed to restructuring, where the fuel component of electric rates tend to reflect a weighted average of the utilities’ fuel costs. There is some evidence that pricing behavior by competitive retailers changed when the retailers affiliated with the incumbent utilities were permitted some pricing flexibility, resulting in a reduction in prices.     

Landscaping Attributes and Property Buyers' Profiles: Their Joint Effect on House Prices

This paper investigates the effect of environmental features on house values while focusing on the interactions between landscaping attributes and home buyers' profile. The originality of this study rests on the assumption that, while neighbourhood characteristics translate into distinct sub-markets and primarily set the structure of house prices, individual home buyers' preferences, under specific market conditions, also affect values. The study benefits from two distinct, although related data sets on the single-family segment of Quebec City's housing market: while landscaping features were obtained via an extensive field survey of houses sold between 1993 and 2000, a detailed phone survey of related homeowners' family status, age and income profiles is being conducted since 2000. Findings suggest that household profile and structure do shape landscaping preferences and that utility patterns of homeowners may be best understood by looking at interactions between the two sets of variables. Considering that population aging is a major issue for economic and social planners, such a conclusion should be accounted for in housing policy design.

四川省工业企业电价承受能力分析

目前，四川电网电价水平偏低，造成电力投资项目难以还本付息。电力建设资金利润率低，直接影响到电力企业的简单再生产和扩大再生产。因此，适当提高电价水平已是大势所趋。不过，电网电价提高到什么样的水平，这是一个重要、复杂、敏感的全局性问题。电价是否合理，对于国民经济的发展、能源的节约、电力工业自身的发展及其广大用户的利益都有着重要的影响，因此，研究电力用户对电价的承受能力，分析电价对用户和社会各方面的影响，是十分必要的。     

Mapping the Presidential Election Cycle in US stock markets

This paper shows that in the almost four decades from January 1965 through to December 2003, US stock prices closely followed the 4-year Presidential Election Cycle. In general, stock prices fell during the first half of a Presidency, reached a trough in the second year, rose during the second half of a Presidency, and reached a peak in the third or fourth year. This cyclical trend is found to hold for the greater part of the last ten administrations, starting from President Lyndon Johnson to the administration of President George W. Bush, particularly when the incumbent is a Republican. The empirical results suggest that the Republican Party may have greater cause to engage in active policy manipulation to win re-election than their Democratic counterparts. There is irony in that bullish runs in the stock market have tended to coincide with sub-periods under Democratic administrations. The existence of the Presidential Election Cycle shown in the paper may constitute an anomaly in the US stock market, which could be useful for investors.
