  • Finally, mobile element based markers are expected to be co-dominant. However, despite the fact that they are extremely useful for population genetics, all mobile element based markers have the same drawback: difficultly of data interpretation and uncertainty about the true nature of the polymorphism. Specifically, the question may arise as to whether differences in banding patterns are due to the absence or presence of retrotransposons, or are caused by some other mechanism, e.g. indels or restriction site loss.

  • Attanasio and Lechene (2002) estimate Engel curves using municipality wage as an instrument for consumption. They find more reasonable results than when household income is used as an instrument. We follow them and use municipality wage as an instrument for total consumption. This obviously precludes the introduction of community fixed effects. In this case the main identification assumption is that municipality wage is not correlated with the error term once the effect of other covariates have been taken into account.

  • As an example, suppose an insurer wrote a $400 commercial liability policy lasting one year, effective October 1, 2000. By December 31, 2000, only one quarter of the policy term would have expired, so under a “deferral-matching” approach only one quarter, i.e., $100, of the premium should be recognized as income. These deferral-matching approaches generally utilize an account known as “written premiums”. Written premiums for a policy during a reported period are generally defined as the amount of premium charged for that policy during the reporting period.

Though direct comparisons are not appropriate, this amount is equivalent to about two-thirds of total value of MF investments covered in Table-V. The amount covered in Table-V is also very close to the share of equity in net assets of MFs arrived by us. In a sense, quite a high proportion of...

In addition to sounding an alarm, which must sound for at least 7 s, oxygen failure warning devices are also linked to a gas shut-off device. Anaesthetists must be aware of both the tone of the alarm and also which gases will continue to flow on the particular model of anaesthetic machine in use....

  • The data confirm the expected role of population and income. Early- and middle-adopting DMAs had, on average, five times larger populations and 24% larger per capita incomes than late- adopting DMAs. After controlling for log population and income, however, differences between early and late adopters appearmuch more idiosyncratic. Indeed, in regressions controlling for log pop- ulation and income, F-tests show no statistically significant re- lationship between television adoption category and percent high school educated, median age, or percent nonwhite at the DMA level.

  • More recently, Granger (1986) and Johansen and Juselius (1990) proposed to determine the existence of long-term equilibrium among selected variables through cointegration analysis, paving the way for a (by now) preferred approach to examining the economic variables-stock markets relationship. A set of time-series variables are cointegrated if they are integrated of the same order and a linear combination of them is stationary. Such linear combinations would then point to the existence of a long-term relationship between the variables.

  • Until the HIV/AIDS epidemic, mortality levels were expected to continue to decline in all regions. However, this tendency has been reversed in coun- tries where HIV/AIDS is most prevalent, especially in sub-Saharan Africa. Life expectancy at birth is lower in the developing regions than in the more developed regions but it is projected to increase in both less and least develop- ing countries. This is dependent on successful implementation of HIV/AIDS prevention and treatment programs and on other health interventions.

In the medium term, Zimbabwe’s prospects and performance will be largely determined by political developments and how these impact the economy.
