Demographic Analysis of the Human Communities of Tangier and Smith Islands: Part I
Get PDFDemography is defined as the study of population characteristics, such as age structure, sex ratio, and growth rate and also seeks to explain the underlying processes responsible for these characteristics. Populations change with time through the combined effects of births/deaths and immigration/emigration. Although all four of these processes are extremely important, this project focuses on births, survival, and deaths. We collected and analyzed records of age at death that have been preserved in the cemeteries of Tangier Island, Virginia and Smith Island, Maryland. Following our experiences on these Chesapeake islands, we developed hypotheses and used survivorship curves to focus on age specific survivorship for human populations that lived at different times in the past. Our analyses allowed us to learn much about patterns of survival and death today and in the past
U.S. Dollar Swap Yields: An Analysis of the Dynamics of Monthly Changes
No full textJohn Maynard Keynes asserted that the central bank sways the long-term interest rate through the influence of its policy rate on the short-term interest rate. Recent empirical research shows that Keynes’s conjecture holds for long-term Treasury yields in the United States. This article investigates whether Keynes’s claim also holds for the monthly changes in U.S.-dollar-denominated long-term swap yields by econometrically modeling its dynamics using an autoregressive distributed lag (ARDL) approach. The econometric modeling reveals that there is a statistically significant effect of the monthly changes in the Treasury bill rate on the monthly changes in swap yields of different maturity tenors after controlling for a host of macroeconomic and financial control variables. The findings from the econometric models that are estimated render a perspicacious Keynesian perspective on key policy questions and contemporary debates in macroeconomics and finance
