ScienceIndex.com is a Web 2.0 sciences social network established in 1998 to index the very latest news, headlines, references and resources from science journals, books and websites worldwide. The site covers news in all fields of biology, business, chemistry, engineering, geography, health, mathematics and society. In the field of business, the site has now included the two new categories Economics and Finance. While the Economics category covers the production, distribution, and consumption of goods and services, the Finance category covers management of money, banking, investments, credit, and other assets.
ScienceIndex.com’s Business Sciences Category covers commercial, industrial, and professional occupation. Its seven subsections include Accounting, Administration, Economics, Finance, Management, Marketing, and Nonprofits.
ScienceIndex.com’s Economics Sciences Category covers the production, distribution, and consumption of goods and services. It currently contains over 16,100 articles partly derived from over 200 scientific journals. One of the latest additions covers factor shares, business cycles and the distributive loop and investigates how factor shares vary over the business cycle and how their movements fit into Kaleckian analysis. The authors conclude that factor shares may be procyclical and countercyclical at different stages of the business cycle. If factor shares vary in a complex way, Kaleckian models cannot have a stable distributive curve and the economy follows a distributive loop, with different adjustment paths during an upswing and a downswing. Another recent inclusion provides an investigation of international trade and the composition of labor market turnover. The authors state that the composition of labor market turnover influences patterns of international trade. Industries with relatively greater shares of worker turnover export more of total production, and those with higher job turnover export less. High job turnover hinders industry adjustment following trade liberalization. These results highlight the importance of relative turnover shares on either side of the labor market in shaping economic outcomes.
ScienceIndex.com’s Finance Sciences category covers the management of money, banking, investments, credit, and other assets. It currently contains nearly 5,400 articles partly derived from 75 scientific journals. One recently included article in this category asks whether the diversification potential of securitized real estate varies over time and whether investors should care. This paper examines the dynamics of the covariance matrix of return rates for securitized real estate, other company stocks, and government bonds for a cross-section of eight countries. The authors conclude that portfolios selected with a forecasted dynamic covariance matrix are less risky than portfolios constructed with the static matrix. Consequently, passive buy-and-hold investors benefit, because the forecasted dynamic covariance matrix provides better risk assessment. Another article reviews four recent studies that blend behavioral economics and psychology. These studies provide evidence for a dual-process decision model for risk that incorporates both reason and fear and show consumers responses to perceived risk as a mix of proportional and dichotomous responses that are relatively more continuous in situations where deliberation is possible, and more dichotomous in emotional or stressful circumstances.
ScienceIndex.com currently contains over 1.37 million stories distributed among 75 categories. 75,248 users monitor nearly 8,200 journals covering the broad spectrum of sciences.
