This paper constructs a general equilibrium search-matching model with heterogeneous workers. Workers choose whether to invest in general human capital or specific human capital when they enter the labor market. We analyze how unemployment benefits affect the choice of the type of human capital investment.

The innovative idea of introducing a third party (Ronen,2002) into the agency relationship has motivated our proposal of a co-payment scheme as a solution to financial misreporting. In the co-payment scheme, both the client firm and a third party such as FASB are asked to share the auditing fee. We will demonstrate that the participation of a third party can create an endogenous collusion cost ...

| We analyze a slotted DSCDMA system to guarantee QoS requirements for realtime tra c [1]. A Markovian analysis for realtime tra c and an equilibrium point analysis (EPA) for non-realtime tra c are applied in a heterogeneous environment. Packet losses for realtime tra c, delay times for non-realtime tra c, and wireless link utilization are derived.

the concentrations and speciation of mo, together with fe, cu, and zn, in nver river sediments impacted with mo mining activities in western liaoning, northeast china, were investigated withgeochemical method. using the x-ray fluorescence and x-ray diffraction, the characterizations of metals in tailings ponds deposited along the nver river bank were analyzed. analysis and comparison of the con...

abstract spacing between check dams depends on the stream bed slope, effective height of check dams and slope of deposited sediments behind the check dams. the slope of deposited sediments is more important than the other two factors because of complications in the way of its occurrence and its measurement after several years of dam construction. this research presents the effective factors aff...

Marine sediment with an input of particulate organic matter was incubated to simulate the early aging process. On the sediment after various incubation periods, adsorption and desorption tests were conducted for three selected organic micropollutants: bisphenol A (BPA), 17α-ethinyl estradiol (EE2), and phenanthrene (Phe). The results showed significant sediment organic matter (SOM) decompositio...

Although recent studies have revealed more widespread occurrences of magnetofossils in pre-Quaternary sediments than have been previously reported, their significance for paleomagnetic and paleoenvironmental studies is not fully understood. We present a paleo- and rock-magnetic study of late Miocene marine sediments recovered from the Guadalquivir Basin (SW Spain). Well-defined paleomagnetic di...
