Contribution of forest provisioning ecosystem services to rural livelihoods in the Miombo woodlands of Zambia

This paper examines the contribution of forest provisioning ecosystem services (FPES) to rural households and assesses the contributions of forests to the annual incomes of households in Africa’s Miombo woodlands. The study employed focus group meetings, in-depth interviews, and interviews of households, as stratified by wealth class and head of household gender in Copperbelt, Zambia. The results show that FPES are vitally important in providing food, medicine, fodder, and construction materials to rural livelihoods. FPES provided 43.9 % of the average household’s income and contributed a 10 % income equalisation effect among households, as revealed by the Gini-coefficient analysis. Poorer households received a lower mean annual income from forests than did their intermediate and wealthy counterparts, but in relative terms, forest income made the greatest contribution to the total household incomes of poor households. When stratified by gender, forests contributed 44.4 and 41.8 % of the income of male- and female-headed households, respectively. The study indicates that wealth, rather than gender, was the key determinant of a household’s engagement in the sale of FPES. The inter- and intra-community differentiation in the use and sale of FPES, as revealed in this study, enables more effective targeting of forest management interventions and informs efforts to reconcile the goals of poverty reduction and forest conservation.     

Welfare Systems,Support Networks and Subjective Well-Being Among Retired Persons

In this article welfare systems and support networks are empirically analyzed to determine which generate the highest level of subjective well-being among retired persons. Propositions derived from support network theories and national welfare system typologies have been analyzed using causal models that indicate the influence of the various welfare systems and support networks on subjective well-being. The data was taken from the Social Relations and Social Support Systems module of the 2001 International Social Survey Program. The results indicate that liberal welfare systems generate the highest level of subjective well-being. This correlates with a lower degree of confidence in the welfare state, greater interpersonal trust and greater belief in individuals and their capacity to secure their own well-being. In the sphere of material well-being the subjective well-being of individuals is affected by a greater trust in people than in the state.     

Preliminary evidence regarding the hypothesis that the sex ratio at sexual maturity may affect longevity in men

In human populations, variation in mate availability has been linked to various biological and social outcomes, but the possible effect of mate availability on health or survival has not been studied. Unbalanced sex ratios are a concern in many parts of the world, and their implications for the health and survival of the constituent individuals warrant careful investigation. We indexed mate availability with contextual sex ratios and investigated the hypothesis that the sex ratio at sexual maturity might be associated with long-term survival for men. Using two unique data sets of 7,683,462 and 4,183 men who were followed for more than 50 years, we found that men who reached their sexual maturity in an environment with higher sex ratios (i. e., higher proportions ofreproductively ready men) appeared to suffer higher long-term mortality risks than those in an environment with lower sex ratios. Mate availability at sexual maturity may be linked via several biological and social mechanisms to long-term survival in men.     

DID TARP DISTORT COMPETITION AMONG SOUND UNSUPPORTED BANKS?

This study investigates if the Troubled Asset Relief Program (TARP) distorted price competition in U.S. banking. Political indicators reveal bailout expectations after 2009, manifested as beliefs about the predicted probability of receiving equity support relative to failing during the TARP disbursement period. In addition, the TARP affected the competitive conduct of unsupported banks after the program stopped in the fourth quarter of 2009. Loan rates were higher, and the risk premium required by depositors was lower for banks with higher bailout expectations. The interest margins of unsupported banks increased in the immediate aftermath of the TARP disbursement but not after 2010. No effects emerged for loan or deposit growth, which suggests that protected banks did not increase their market shares at the expense of less protected banks. (JEL G21, G28, L51)     

Exponentiated-exponential geometric regression model

A regression model, based on the exponentiated-exponential geometric distribution, is defined and studied. The regression model can be applied to count data with under-dispersion or over-dispersion. Some forms of its modifications to truncated or inflated data are mentioned. Some tests to discriminate between the regression model and its competitors are discussed. Real numerical data sets are used to illustrate the applications of the regression model.     

Friendship and subjective well-being in Spain: A cross-national comparison with the United States

This paper empirically examines three propositions which are derived from network theory, particularly the relationship between friends' network and happiness level as a subjective well-being indicator. Using friendship network data obtained from 1985 NORC General Social Survey for the U.S., and from 1993 CIRES Social Survey for Spain, a cross-national comparison between Spain and the U.S. was performed. Results are compared with previous major Davis' and Burt's works for the U.S. It was found that there was a significant, strong association between happiness and friends' network size for both countries, and that there was not a great happiness difference between them. However, close friendship has a contrary effect on happiness when data from both countries are compared. Concerning socioeconomic status, happiness increased with income, although this effect was higher in Spain than in the U.S.Financial support for this project was provided by the Department of Sociology, UMA, and University Computer Center.

Vital Satisfaction as a Health Indicator in Elderly Women

The long life expentancy of the elderly motivates interest in their quality of life. Our study analyzes vital satisfaction as a global indicator of the three dimensions (physical, mental, and social) of the quality of life in relation to health. The subjects were 310 women, with an average age of 71.22 years old (SD 6.72), with minimum education, and active aging. The reliability was examined with the COOP-WONCA Charts and the Nottingham Health Profile. The results show that vital satisfaction significantly correlates with the three dimensions of health, in particular with the mental domain.     

MONITORING OF WORKERS AND PRODUCT MARKET COMPETITION: THE ROLE OF WORKS COUNCILS

Often the consent of worker representations, such as works councils, is required before firms are allowed to install technologies that monitor workers' behavior. Absent monitoring, workers produce low output, while at the same time receiving an information rent. To gain the works council's consent to the installation of a monitoring technology, firms need to compensate workers for the lost information rent. Hence, by making it more costly to produce high output, works councils can serve firms as an instrument to commit to low output levels. This provides a rationale for why works council rights are not opposed more strongly by employers. (JEL D43, D86, J83, L13)     

Finance and the Sources of Growth at Various Stages of Economic Development

This article studies the effects of financial development on the sources of growth in different groups of countries. Recent theoretical work shows that financial development may affect productivity and capital accumulation in different ways in industrial versus developing countries. This hypothesis is tested with panel data from 74 countries using GMM dynamic panel techniques. Results are consistent with the hypothesis: finance has a strong positive influence on productivity growth primarily in more developed economies. In less developed economies, the effect of finance on output growth occurs primarily through capital accumulation.
