We investigate the impact of housing wealth, credit availability and financial distress on college enrolment decisions. We find that housing wealth is negatively related to enrolment in public schools and positively related to enrolment in private schools. This evidence suggests that, on average, students substituted away from private schools towards public institutions during the recent financial crisis.  相似文献

As the hunting, butchering, processing, and consumption of bushmeat is a potential source of human Ebola virus (EV) infections, the extent to which bushmeat is a substitute for food produced and sold in the formal sector suggests that the relative price of food could matter for the incidence of human EV infections. This paper considers if productivity in the food sector is a driver of human EV infections in sub‐Saharan Africa. We estimate count data specifications of country level human EV infections as a function of food sector productivity in sub‐Saharan Africa over the 1976–2013 time period. Our parameter estimates suggest that if productivity in the food sector was on average 1 per cent higher over the 1976–2013 time period, the incidence of human EV infection would have been 42.5 per cent lower. This is consistent with bushmeat being a substitute for food produced in the formal sector, as food productivity increases lower the price of formal food relative to bushmeat. Our findings suggest that as productivity in the formal food sector is a driver of human EV infections in sub‐Saharan Africa, policy interventions that increase food productivity would enable Millennium Development Goal outcomes related to hunger, disease mitigation, and sustainability of wildlife.  相似文献

What causes adolescents to develop consumer’ ethical beliefs? Prior research has largely focused on the negative influence of peers and negative patterns of parent–child interactions to explain risky and unethical consumer behaviors. We take a different perspective by focusing on the positive support of parents and peers in adolescent social development. An integrative model is developed that links parental and peer support with adolescents’ self-worth motives, their materialistic tendencies, and their consumer ethical beliefs. In a study of 984 adolescents, we demonstrate support for a sequential mediation model in which peer and parental support is positively related to adolescents’ self-esteem and feelings of power, which are each associated with decreased materialism as a means of compensating for low self-worth. This reduced materialism is, in turn, associated with more ethical consumer beliefs.  相似文献

This article describes some of the work of Antitrust Division economists over the past year, with a focus on modeling. It begins by illustrating the mapping from evidence to prediction using tools for assessing the effects of mergers using Bertrand, Cournot, and auction models. It then turns to two hot topics in competition policy: the implications of claims of increasing margins for merger enforcement and the validity of claims of increasing concentration. Finally, it considers how mergers affect prices in bargaining models.  相似文献

Private equity performance, both for buyouts and venture capital, has been highly cyclical: periods of high fundraising have been followed by periods of low performance. Despite this seemingly predictable variation, we find modest gains, at best, to pursuing realistic, investable strategies that time capital commitments to private equity. This occurs, in part, because investors can only time their commitments to funds; they cannot time when commitments are called or when investments are exited. There is a high degree of time-series correlation in net cash flows even across commitment strategies that allocate capital in a very different manner over time.  相似文献

How does social distancing affect the reach of an epidemic in social networks? We present Monte Carlo simulation results of a susceptible–infected–removed with social distancing model. The key feature of the model is that individuals are limited in the number of acquaintances that they can interact with, thereby constraining disease transmission to an infectious subnetwork of the original social network. While increased social distancing typically reduces the spread of an infectious disease, the magnitude varies greatly depending on the topology of the network, indicating the need for policies that are network dependent. Our results also reveal the importance of coordinating policies at the ‘global’ level. In particular, the public health benefits from social distancing to a group (e.g. a country) may be completely undone if that group maintains connections with outside groups that are not following suit.

Abstract:

The religious economics (not economics of religion) concern here is the relationship between the World Zionist Organization (WZO) and Israel, which is known as a geopolitical power in its region and which is also known as an economic success story. Joseph Schumpeter and Karl Polanyi explained how the political economy of medieval Europe was influenced and guided by Christian morality. This paper extends the analysis of religious economics by using the social fabric matrix of original institutional economics to define and structure the integration of the WZO, Israel, and the Diaspora countries. This allows us to observe how to conduct such work and to learn how Israel is guided and influenced by the WZO. It also helps to explain Israel’s “risk of tearing itself apart” as noted in a recent article in the New York Times.  相似文献

Abstract:

The instrumental-ceremonial dichotomy is the analytical concern emphasized in instrumental analysis by original institutional economists for making welfare decisions. Paul Dale Bush and Wolfram Elsner explained that warranted criteria are required in order to conduct instrumental analysis. The concern for criteria led to an examination of multiple criteria decision analysis in health technology assessment in order to improve instrumental analysis. Health technology assessment (HTA) is one of the most active and extensive areas of analysis for policy making because medical technology changes very rapidly, expenditures on it are high and growing, it can harm as well as help, and there is intense personal concern by citizens who want wellness. Although HTA, especially with regard to the analysis of multiple criteria, has made considerable progress, its appraisal has been a disappointment. Thus, the purpose of this paper is to critique aspects of multiple criteria HTA in order to further develop instrumental analysis.  相似文献
