The Effects of Spousal Health on the Decision to Smoke: Evidence on Consumption Externalities, Altruism and Learning Within the Household

Married individuals are healthier than single individuals though the reasons are not well understood. Individuals with spouses/or partners are less likely to smoke. We explore the relationship between health and marital status by analyzing three potential channels through which marriage affects smoking, i.e., consumption externalities (one spouse's smoking affects the other spouse's welfare), altruism (one spouse reduces smoking in response to the other spouse's bad health), and learning about risks of smoking from the health experience of one's spouse. We find spousal health does not affect smoking due to altruism or learning within the household but do find evidence for consumption externalities.

公开市场操作公告对中国股市交易行为的影响

基于MRR结构模型,利用广义矩估计方法,从信息不对称和流动性成本角度考察了央行公开市场操作公告对股票市场交易行为的影响。实证结果表明,公开市场操作披露前股票市场的信息不对称程度、流动性成本并未发生显著变化,公开市场操作披露后30分钟内,信息不对称程度增加,流动性成本下降。在考虑了公开市场操作未预期的利率变化具体内容后,所得结果并没有显著变化。     

Strengthening communities through women's self help groups in South India

This article reports on an evaluation of women's Self Help Groups(SHGs) in an area in south India. Groups were evaluated, notin terms of their success as microcredit schemes, from a financialperspective, but in relation to their contribution to genderdevelopment. Evidence emerged that women perceived changes intheir identity towards working collectively to influence forchange at the village and panchyat levels. They engaged in communityand social action programmes, both at the local level and byjoining with issues beyond the local. When considered withinconstructs of empowerment, capability poverty, citizenship,and participation in democratic processes, such SHG outcomes,and the community development processes that accompany theirwork, can be seen to make a modest but significant contributionto broader transformations of oppressive structures.

Prehistoric landscapes of the sonoran desert Hohokam

The Hohokam of southern Arizona are noted for greater duration of settlement than other major agricultural traditions in the archaeological record of the southwestern United States, including the Anasazi and Mogollon. The 40,000 square mile area inhabited by the Hohokam is marked by low elevation desert basins, but encompasses a range of topographic and climatic variability that shaped opportunities for prehistoric farming technologies. Irrigation from rivers was frequently associated with the longterm persistence of individual sites, while floodwater farming along ephemeral drainages was more often correlated with continuous occupation of hydrologically favored zones. Renewal of fields by waterborne nutrients and efficient practices in the use of natural resources countered the limited mobility options afforded by the Hohokam environment.In spite of a restrictive agricultural setting and an essentially static suite of productive technologies over many centuries, relationships among population, settlement, and landuse were redefined in evolving social and economic configurations. An example from the Tucson Basin illustrates differentiated patterns of settlement and agriculture arising in conjunction with increased levels of population and territorial integration in the late prehistoric period. Community organization among interrelated settlements incorporated a diversity of topographic zones and agricultural technologies in this high-risk context for prehistoric cultivators.
