A Model of Fiat Money and Barter
Journal of Economic Theory, 1996Co-Authors: Fumio Hayashi, Akihiko MatsuiAbstract:Abstract We present an infinite horizon model with capital in which fiat money and Barter are two competing means of payment. Fiat money has value because Barter is limited by the extent of a double coincidence of wants. The pattern of exchange generally involves both money and Barter. We find that the Chicago rule is sufficient for Pareto efficiency, while nominal interest smoothing is necessary. For a specific utility function we provide a complete characterization of the patterns of exchange and calculate the range of inflation rates over which a stationary monetary equilibrium exists.Journal of Economic LiteratureClassification Numbers: D51, E42, E52.

captive propagation reproductive biology and early life history of etheostoma wapiti boulder darter e vulneratum wounded darter and e maculatum spotted darter
Southeastern Naturalist, 2016Co-Authors: Crystal L Ruble, Patrick L Rakes, J R Shute, Stuart A WelshAbstract:Abstract Reproductive biology and early life-history data are important for understanding the ecology of fishes. In 2008, we conducted captive propagation studies on 3 species of darters of the subgenus Nothonotus: Etheostoma wapiti (Boulder Darter), E. vulneratum (Wounded Darter), and E. maculatum (Spotted Darter). The length of spawning period and associated range of water temperatures for the Wounded Darter exceeded that of the Spotted Darter and Boulder Darter. The mean number of eggs produced per female was lowest for Boulder Darter and highest in the Wounded Darter. The Boulder Darter had the highest percent of eggs hatched, the lowest percent larval to juvenile stage survivorship, and the lowest mean number of juveniles produced per female. Egg diameters at deposition and prior to hatch were smallest for the Spotted Darter. If reproductive biology and early lifehistory information from captive fishes represent that of wild populations, then the data obtained during this study are relevant to develo...

Bapanduk (Sistem Barter) di Pasar Terapung Lok Baintan Kabupaten Banjar
Media Jaya Abadi, 2020Co-Authors: Johansen PoltakAbstract:Pasar tradisional merupakan bagian dari ekonomi kerakyatan yang berperan penting dalam memejukan pertumbuhan ekonomi di Indonesia. Sejarah pasar terapung di Kalimantan Selatan bermula dari berdirinya Kerajaan Banjar pada tahun 1520. Salah satunya adalah Pasar Terapung Lok Baintan. Aktivitas pasar ini dilakukan di tengah sungai dengan menggunakan perahu atau jukung. Transaksi jual beli di pasar terapung ini tidak hyanya menggunakan uang, tetapi juga dengan sistem Barter yang dalam bahasa Banjar disebut bapanduk. Penulisan tentang bapanduk ini bertujuan agar dapat dicapai suatu pemahaman tentang perilaku atau sikap masyarakat terhadap sistem Barter di pasar apung tersebut

Captive propagation, reproductive biology, and early life history of Crystallaria cincotta (Diamond Darter), Etheostoma wapiti (Boulder Darter), E. vulneratum (Wounded Darter), and E. maculatum (Spotted Darter)
The Research Repository @ WVU, 2013Co-Authors: Ruble CrystalAbstract:Reproductive biology and early life history data are important for understanding the ecology of fishes, and can be used for the management and conservation of rare species. During 2008--2012, a captive propagation study was conducted on Crystallaria cincotta (Diamond Darter), a rare species with a single extant population in the lower Elk River, WV. Also, captive propagation studies were conducting during 2008 on three species of darters of the subgenus Nothonotus: Etheostoma wapiti (Boulder Darter), E. vulneratum (Wounded Darter), and E. maculatum (Spotted Darter). Water temperatures during Diamond Darter spawning ranged from 11.1--23.3°C. Females and males spawned with quick vibrations to bury eggs in fine sand in relatively swift clean depositional areas. Egg size was 1.8--1.9 mm, and embryos developed within 7--11 days. Diamond Darters were 6.7--7.2 mm TL at hatch. Larvae ranged from 9.0--11.0 mm TL following a 5--10 day period of yolk sac absorption. Larvae were provided Artemia nauplii, Ceriodaphnia dubia neonates, Brachionus rotifers, and powdered foods (50--400 microns). Diamond Darter larvae did not feed in captivity, except for cannibalizing other larvae. Larvae survived for a maximum of 11 days. Larvae had relatively large gapes and teeth, suggesting possible larval piscivory and a need for alternative food sources during captive propagation. During the Nothonotus study, the length of spawning period and associated range of water temperatures for the Wounded Darter (89 days, 16.0--24.0°C) exceeded those of the Spotted Darter (46 days, 17.0--22.5°C) and Boulder Darter (48 days, 17.0--22.5°C). Eggs produced per female were least in the Boulder Darter (163), intermediate in the Spotted Darter (191), and highest in the Wounded Darter (345). Diameters of eggs at deposition and prior to hatch were least for Spotted Darter (1.9--2.0 mm, and 1.9--2.1 mm), intermediate for Wounded Darter (2.1--2.2 mm, 2.4--2.5 mm), and largest for Boulder Darter (2.2--2.4 mm, 2.4--2.6 mm). Lengths of larvae at hatch and at the start of first fin development varied in a similar pattern: Boulder Darter (8.5--9.1, 14.0--15.0), Wounded Darter (7.7--8.0, 13.5--14.0), and Spotted Darter (6.5--7.0, 12.0--13.0 mm). Overall production per female was lowest in Boulder Darters (61 juveniles/ female), intermediate in Spotted Darters (86 juveniles/ female), and highest in Wounded Darters (90 juveniles/ female)
