军队RFID市场机遇与厂商进入策略

信息化战争具有预警时间短、对抗强度大、破坏性强等突出特点。物资的消耗量日益剧增，战争对物资表现出前所未有的依赖性，军事物流的地位和作用日益突出。这种新的战争形态对军事物流提出了“快速反应”和“精确保障”这两大基本要求。“快速反应”是指信息化战争中可以用来达成突然性的手段比以往明显增多，战争突然爆发以及瞬息万变的战场要求军事物流必须具备快速展开和部署物流设施设备、快速前送和补充物资装备的能力；“精确保障”是指信息化战争面临的是立体的、非线式、大纵深的战场环境。在这样的环境中，军事物流必须由过去的“线”和“面”向立体式发展，在保障过程中实施准确调控，随战场形势的改变而随时转换物资的流量和流向。恩格斯指出，“一旦技术上的进步可以用于军事目的，并且已经用于军事目的，它们便立刻几乎强制地，而且往往违反指挥官的意志而引起作战方式上的改变甚至变革。”RFID就是这样的技术。     

The baby boom,the baby bust,and the housing market

This paper explores the impact of demographic changes on the housing market in the US, 1st by reviewing the facts about the Baby Boom, 2nd by linking age and housing demand using census data for 1970 and 1980, 3rd by computing the effect of demand on price of housing and on the quantity of residential capital, and last by constructing a theoretical model to plot the predictability of the jump in demand caused by the Baby Boom. The Baby Boom in the U.S. lasted from 1946-1964, with a peak in 1957 when 4.3 million babies were born. In 1980 19.7% of the population were aged 20-30, compared to 13.3% in 1960. Demand for housing was modeled for a given household from census data, resulting in the finding that demand rises sharply at age 20-30, then declines after age 40 by 1% per year. Thus between 1970 and 1980 the real value of housing for an adult at any given age jumped 50%, while the real disposable personal income per capita rose 22%. The structure of demand is such that the swelling in the rate of growth in housing demand peaked in 1980, with a rate of 1.66% per year. Housing demand and real price of housing were highly correlated and inelastic. If this relationship holds in the future, the real price of housing should fall about 3% per year, or 47% by 2007. The theoretical model, a variation of the Poterba model, ignoring inflation and taxation, suggests that fluctuations in prices caused by changes in demand are not foreseen by the market, even though they are predictable in principle 20 years in advance. As the effects of falling housing prices become apparent, there may be a potential for economic instability, but people may be induced to save more because their homes will no longer provide the funds for retirement.     

Matching structure and strategy: Towards a market orientation in health care

The introduction of an ‘internal’ or ‘managed’ market mechanism into the National Health Service required fundamental structural reorganisation, involving the separation of purchaser and provider functions. While a degree of structural change has occurred among the emergent purchasing organisations subsequent to the initial reforms, there is a lack of corresponding evidence of ongoing structural change in acute provider units. Despite the existence of a direct relationship between organisational structure and strategy, the extent of change in the organisational structure of hospitals is questionable. Indeed at the macro level current acute hospital structures, that is NHS Trusts, are remarkably similar to ‘pre-reform’ structures, despite the unsuitability of these structures for the market orientation required by the internal market. Such prevalence arguably reflects the marginal effect that current managerial structures have had on those delivering services and the predominance of the medical hierarchies. Specifically, those responsible for the marketing of hospital services in current structures are not directly linked to those who deliver the service, in spite of the introduction of clinical directorate structures. Part of a broader study of the market behaviour of acute NHS Trusts in Scotland, this paper explores the organisational avenues open to health care providers to overcome this separation in the pursuit of market-led service delivery and concomitant market orientation.

The baby boom, the baby bust, and the housing market A second look

I re-examine Mankiw-Weil's (MW) claim that house prices will fall 47% by 2007. MW argue that the arrival of the Baby Boom generation at adulthood drove up prices during the 1970s. When the beginnings of the Baby Bust generation matured in the 1980s, prices softened. When this generation arrives in earnest, prices will collapse. I make three points: (1) The regression upon which MW hang their prediction has an implausible -8.1% trend, which drives their prediction. (2) Demand directly influences the rental price; the asset price (MW's variable) is influenced by demand only indirectly. I re-run MW's regression, replacing the asset price with the rental price, and their prediction disappears. (3) Relying on data presented by MW, I show that housing consumption rose during the 1970s, after adjusting for income growth. Just when MW say the asset price of housing was rising, consumers behaved as if the price were falling. Consumers were right: The rental price fell by approximately 20% during the 1970s.     

Convergence of a market related game strategy

A special case of the adjustment process for competing firms, introduced elsewhere, is analysed. It is proved that all equilibrium states are characterised by the vanishing of the Jacobian of the payoff functions of the market game, and that under suitable initial conditions the process is a contraction mapping, implying convergence to equilibrium.     

The baby boom and the housing market: Another look at the evidence

Based on tests for cointegration, the growth of housing demand resulting from the Baby Boom appears to be the major factor behind increased real residential investment, but not the major factor behind increased real housing prices in the postwar U.S. The housing market also passes a simple test for efficiency.
