  • A number of barriers stand in the way of mainstream adoption of personal manufacturing technologies that discourage widespread home, school and business use. A chief barrier is the “chicken and egg” paradox, where today’s current consumer and education markets for personal fabrication technologies is too small to attract the attention of companies, discouraging company investment in creating products and services, hence failing to attract more consumers.

  • All combined or “synthetic” measures which try to measure environmental and economic changes in one indicator can be dismissed as over-simplistic. Beyond this, however, there is also the serious question of how meaningful it is to try to produce an estimate of national sustainability rather than assess the benefits and impacts of particular activities within a country.

  • In this section we look at data concerning 10-year government bond yields. Although our main interest is the default risk, this presents only one channel through which fiscal policies can affect long-term yields. There are other channels operating through monetary-fiscal interaction, which should be reflected in the evolution of yields. Therefore we start our descriptive analysis in this section by looking at yields, forward rates and inflation expectations at a weekly frequency. Then we move to an analysis of interest rate swap spreads, at a weekly and daily frequency.

  • Information -- or more precisely, better information -- can be viewed much like any other commodity in that it is costly to acquire and provides benefits to the user. The goal is to identify the kinds of situations in which improvements in data or methods are likely to yield the greatest net benefit. From an economic standpoint, information itself has little intrinsic value. Instead, information acquires value when it facilitates optimizing behavior. That is, better information can lead to changes in actions, changes that themselves create value.

  • Since 1980, the principal form of crop loss assistance in the United States has been provided through the Federal Crop Insurance Program. The Federal Crop Insurance Act of 1980 was intended to replace disaster programs with a subsidized insurance program that farmers could depend on in the event of crop losses. Crop insurance was seen as preferable to disaster assistance because it was less costly and hence could be provided to more producers, was less likely to encourage moral hazard, and less likely to encourage producers to plant crops on marginal lands.

  • The first-order effects of relaxed bank entry restrictions have been favorable, both within the U.S. and across countries. Internationally, the benefits of foreign entry seem to depend on the level of development, but at least for developing nations entrants are more efficient than incumbent banks and the stiffer competition seems to improve overall bank efficiency. In contrast to these first-order effects, the stability implications of increased entry are less obvious.

  • Orthographic projections-that is, plans and sections-are one of the most valuable representational tools architects have at their disposal. They are an indispensable communication and design device. They have also contributed to a prominent digital fabrication method. With computer modeling, deriving sections is no longer a necessarily two-dimensional drawing exercise. In fact, it is no longer an exercise in projection at all but a process of taking cuts through a formed three-dimensional object.
