Ebook Wage Distributions by Bargaining Regime: Linked Employer-Employee Data Evidence from Germany

Submitted by wulan on Wed, 06/09/2010 - 06:31

Trade unions bargain for higher wages, equal pay, fair working conditions, or employment protection (Freeman and Medoff 1984). Classical models such as monopoly unions, right-to-manage models, or efficient bargaining predict a monotonic positive relationship between union power and the level of bargained wages; see the surveys of Farber (1986), Oswald (1985), and Naylor (2003). Some more recent studies emphasize effects on higher moments of the wage distribution.

In line with an insurance motive for union representation of risk-averse workers (Agell and Lommerud 1992, Burda 1995), union impact compresses the wage distribution relative to the distribution of productivities. By enforcing “equal pay for equal work” unions further seek to limit favoritism and discrimination by superiors and colleagues, and to encourage solidarity among the work force (Freeman 1982). Union-bargained wages may serve as wage floors, thereby narrowing the distribution of wages from below.

Ebook Perpectives On Credit Card Use And Abuse

Submitted by wulan on Wed, 07/22/2009 - 03:36

Between 1991 and 2001, consumer credit debt almost tripled from $247 billion to $700 billion. It is estimated that today more than 75% of Americans are credit cardholders, owning an average of 4.2 cards per person. Experts predict that by the year 2015, the percentage of the U.S.population owning at least one credit card will grow to 80% (Hogarth, 2002). This study will investigate the various issues related to consumer credit use. Several types of credit cards are available to consumers, such as bankcards, gasoline, travel and entertainment cards, store cards, and affinity cards. Some are limited to a certain chain of stores, while some offer benefits to reward usage.

Credit card company’s segment cardholders into categories characterized by their spending behavior and balance carried forth. Cardholders have also been segmented by academics into two groups, convenient users and the credit users, based on their spending habits. However, a more common method for classifying cardholders is by income. A study by the U.S. Census Bureau found that 96% of consumers who earn more than $100,000 possess at least one credit card, while only 29% of consumers earning less than $10,000 have one. The study also observed a significant correlation between income class and propensity to carry a balance over to the following month (US Census Bureau, 2003).

Ebook Environmental Management Accounting ?EMA?Workbook

Submitted by wulan on Thu, 09/03/2009 - 03:57

In a three-year plan spanning between 1999 and 2001, the Ministry of Economy, Trade and Industry commissioned the Japan Environmental Management Association for Industry, within which an Environmental Accounting Committee (for a list of committee members, refer to the end of this workbook) was set up, to conduct investigative research. A report on the results from this investigative research has been summarized in this document, which is entitled “Environmental Management Accounting Workbook.”

Environmental accounting can be classified broadly into external environmental accounting, in which information is disclosed outside of a company, and internal environmental accounting, which contributes to business management within a company. In recent years, internal environmental accounting has also come to be referred to as environmental management accounting (EMA), and in this document, the term “environmental management accounting” will be used.
