Two opposing models of public-goods undersupply are those of “market failure” and “government failure”. Empirical work on the relative explanatory power of these two frameworks has been limited by the scarcity of acceptable data. The case of climate-controlled walkways in major urban cores is a rare instance where such difficulties can be overcome. We investigate the supply of CCWs in 55 large city-cores in North America. We find that (1) CCW networks are well-supplied by market forces, when (2) such forces are not frustrated by government policy. We also find evidence that (3) rules-based regimes dominate discretion-based regimes. These results are consistent with the position that the “government-failure” paradigm is a viable alternative to the traditional “market failure” paradigm.  相似文献

"This article compares two sources of data on Mexico-U.S. migration, based on radically different methodologies: the Mexican Migration Project (Promig) and the National Survey of Population Dynamics (Enadid).... This comparative study shows that a micro-social design drawing on multiple community samples, such as Promig, can solve the methodological conflict between specificity and representativeness.... The authors' research also highlights the problem of selectivity and specificity entailed by traditional surveys such as Enadid as a result of restricting their samples to international residents in Mexico and attempting to explain such a complex, socioeconomic process using a limited number of variables."

Health care reform became a premier issue on the U.S. policy agenda in the 1990s. While the comprehensive proposal put forth by President Clinton failed, states and the federal government successfully pursued a variety of lesser initiatives. This article focuses on a set of reforms intended to make private health insurance more accessible and affordable to individuals and workers in small firms. It outlines the key arguments made by experts to justify stronger regulation of health insurance and the options and difficult tradeoffs that must be considered in policy design. It then examines the scope and strength of legislation adopted by 45 states and the federal government from 1990 to 1996. The substantial variation in state policies demonstrates that even though insurance market reform was the one issue that commanded nearly universal support in the health care debate, few design features were universally accepted by those who crafted the reforms. The article concludes by assessing the pattern of state and federal action. The reforms represent some progress on nominal access to insurance but little progress on the affordability of insurance for individuals and small groups. Few of the reforms present a serious challenge to existing practices and interests of the insurance industry. This pattern of policy design reflects the logical and political constraints of incrementalism. In a system where insurance coverage is voluntary, changes to increase access for one group tend to increase costs and thereby decrease access for another segment of the population. In addition, because incremental reforms will not attract sustained attention and support from the general public, it is politically difficult to impose substantial new regulation on a powerful industry.  相似文献

Development of depressive tendencies was assessed over a 9-year period in a random sample of 389 Finnish children. Predictors of maternal role satisfaction and hostile child-rearing attitudes, assessed when the children were ages 6 and 9 years, respectively, and a temperament predictor of perceived child difficultness, assessed when the children were age 6 years, were measured using questionnaires designed for this study. Depressive tendencies were assessed by a self-report at age 15 (modification of Beck's Depression Inventory). Using structural equation modeling, we tested a hypothesized model comprising direct as well as mediated effects between the childhood predictor variables and adolescent depressive tendencies. The results indicated support for a similar mediational model in girls and boys. Low maternal role satisfaction and maternal perceptions of child difficultness, measured when children were age 6 years, predicted hostile maternal child-rearing attitudes measured when children were age 9 years, which in turn had a significant direct effect on depressive tendencies among these children during adolescence. The only other direct effect was found solely in girls: Low maternal role satisfaction predicted adolescent depressive tendencies. These results underline the close interplay of child temperament and mothering factors in the development of depressive tendencies in girls and boys.  相似文献
