  • This is a short book. It aims to get across the essential elements of dynamics that are used in modern treatments of the subject. More significantly, it aims to do this through the means of examples. Some of these examples are purely algebraic. But many others consider economic models: both microeconomic and macroeconomic. Macroeconomics is replete with dynamic models – some simple and others quite complex. But this is not true of microeconomics.

  • MANAGING SUPPLY CONTRACTS AND INVENTORY RISKS IN A SUPPLY CHAIN This seems a more accurate characterization of Tiebout markets, as the median U.S. metropolitan area has fewer than a dozen school districts from which to choose. It leads to a substantially different understanding of the market dynamics, as Hoxy’s assumption of competing schools with identical peer groups eliminates the “stickiness” that concern for peer group can create and that is the primary focus here.

  • With the ever-increasing levels of volatility in demand and more and more turbulent market conditions, there is a growing acceptance that individual businesses can no longer compete as stand-alone entities but rather as supply chains. Supply chain management (SCM) has been both an emergent field of practice and an academic domain to help firms satisfy customer needs more responsively with improved quality, reduction cost and higher flexibility.

  • The Santa Fe Institute (SFI) is interested in understanding evolving complex social, biological, and physical adaptive systems in a most general sense (see Cowan et al. 1994). Those of us at SFI interested in the evolution of social behavior have tended to focus on either small-scale societies or on specific aspects of more complex societies, such as the economy.

  • Natural gas is a vital component of the world's supply of energy and an important source of many bulk chemicals and speciality chemicals. It is one of the cleanest, safest, and most useful of all energy sources, and helps to meet the world’s rising demand for cleaner energy into the future. However, exploring, producing and bringing gas to the user or converting gas into desired chemicals is a systematical engineering project, and every step requires thorough understanding of gas and the surrounding environment.

  • VECTOR DISSIPATIVITY THEORY FOR DISCRETE-TIME LARGE-SCALE NONLINEAR DYNAMICAL SYSTEMS WASSIM M. HADDAD, QING HUI, VIJAYSEKHAR CHELLABOINA, AND SERGEY NERSESOV Received 15 October 2003 In analyzing large-scale systems, it is often desirable to treat the overall system as a collection of interconnected subsystems. Solution properties of the large-scale system are then deduced from the solution properties of the individual subsystems and the nature of the system interconnections.

  • One of the most popular organic pesticides, neem, is toxic to non-target species including crustaceans and tadpoles. Neem has been shown to cause the brain disease toxic encephalopathy in children. In mice, it causes chromosomal abnormalities in bone marrow cells and damages the DNA of sperm . Are there any other problems with organic pesticides? We really do not know simply because they are not regulated like the “synthetic” ones.

  • India’s diamond supply was largely exhausted by the early eighteenth century, and the diamond trade moved to Brazil, then later to southern Africa. At the same time, London emerged as the world’s diamond sorting center, and Amsterdam and Antwerp became influential trade centers as well. Diamonds became an even more popular fashion item, worn by royalty and wealthy women at significant social occasions. The 1870 discovery of massive diamond deposits near the confluence of the Vaal and Orange rivers in South Africa was a watershed moment, igniting a diamond rush.

  • Gas supplies and suction To check the correct function of the oxygen failure alarm involves disconnecting the oxygen pipeline on some machines, whilst on machines with a gas supply master switch, the alarm may be operated by turning the master switch off. As repeated disconnection of gas hoses may lead to premature failure of the Schrader socket and probe, these guidelines recommend that the regular pre-session check of equipment includes a ‘tug test’ to confirmcorrect insertion of each pipeline into the appropriate socket....

  • Anything that increases costs of production will tend to increase marginal cost and thus reduce the supply. For example, as wages rise, the supply of goods and services is reduced, because wages are the input price of labor. Labor accounts for about two- thirds of all input costs, and thus wage increases create supply reductions (a higher price is necessary to provide the same quantity) for most goods and services. Costs of materials of course increase the price of goods using those materials. For example, the most important input into the manufacture of gasoline is crude oil,...

  • As for the effect of macroeconomic variables such as money supply and interest rate on stock prices, the efficient market hypothesis suggests that competition among the profit-maximizing investors in an efficient market will ensure that all the relevant information currently known about changes in macroeconomic variables are fully reflected in current stock prices, so that investors will not be able to earn abnormal profit through prediction of the future stock market movements (Chong and Koh 2003).

  • Instrumental variables techniques are required to solve the possible endogeneity of household consumption. The most difficult task is to find a valid instrument for the regression above. The literature on demand systems typically uses income to instrument consumption. If preferences are separable between consumption and leisure, total consumption but not income is relevant to decide on the good shares. However, there are several reasons why household income might not be a valid instrument.
