This paper applies principles of transition to land tenure and squatting in South Africa. Political transition in South Africa reassigned political property rights, which produced contestable, and rent‐seeking incentives for squatting as a means to privatize land and redistribute wealth. Government failure to establish and protect private property rights in a squatter camp resulted in common‐pool problems that resisted private and public resolution with consequent rent dissipation and social loss. In response to this retreat from duty, informal agents emerged to claim their own share of the prize. Without enforceable rules of capture, the growth of squatter camps in South Africa will continue.

This article assesses Canadian banks' ability to realize scale economies and cost complementarities in joint production. The Canadian banking system, with its 10 or so large banks and 50 smaller ones, offers a good database for a study of efficiency, especially since previous work suggests that the system's concentration has had little impact on system competitiveness. This article estimates a system of cost and cost share equations using Zellner's iterative seemingly unrelated regression technique, then evaluates scale economies and cost complementarities from the estimated cost functions' first and second partial derivatives. The article compares a model that classifies deposits as inputs with another that classifies them as outputs. The empirical findings indicate that deposits are better modelled as outputs than inputs; that Canadian banks organize to exhaust available sources of scale economies and economies in joint production; and that conclusions regarding scale economies and cost complementarities differ importantly according to whether deposits are modelled as inputs or as outputs. 相似文献

We describe the quantitative modeling techniques that are used in horizontal merger review for the evaluation of unilateral effects, and discuss how the 2010 Horizontal Merger Guidelines helped legitimize these methods and motivate scholarly research. We cover markets that feature differentiated products pricing, auctions and negotiations, and homogeneous products, in turn. We also develop connections between quantitative modeling and market concentration screens that are based on the Herfindahl-Hirschman Index (HHI).

The power motive, defined as the desire to impact the behavior and emotions of another person, has long been controversial. On one side, the exercise of power has been put forth as a fundamental human need greater in strength than the need to survive. On the other, it has been vilified for its potentially devastating consequences. We argue the latter view is distorted, and, by relying too heavily on it, we have come to misunderstand the essential nature of power and its use by leaders charged with driving performance. It is not the power motive that leads to corruption and tyranny, but rather how the power motive is channeled into behavior by other personality factors. Consequently, those charged with leader selection should place greater emphasis on how individuals with strong power motives differ in how they channel power. Doing so will support the selection of executives best equipped to deliver organizational performance. 相似文献

Estimates of the prevalence and risk of drinking-and-driving are a high-priority need for researchers and policymakers. Levitt and Porter (Journal of Political Economy, 2001, 109(6), 1198–1237) demonstrate how these can be recovered using publicly available information in the Fatality Analysis Reporting System (FARS). Although robust to systematic misreporting and sample selection and far cheaper to implement than surveys, their methodological innovations are largely ignored. We believe this arises partly from difficulty in replicating their results. This article identifies the underlying causes of replication failure and offers practical guidance for future implementation that takes advantage of the current structure of the FARS data. 相似文献

In 2015, the Federal Communications Commission (FCC) imposed common carriage regulation—so-called Title II requirements—on previously unregulated broadband Internet service providers. The regime shift was premised on the FCC’s findings that such rules had demonstrably yielded economic gains. This paper evaluates the FCC’s empirical arguments and finds them uncompelling. Adjustments for inflation or general economic trends eliminate the effects cited by the FCC. Moreover, contrary to the Commission’s assessment, mobile services and broadband markets have shown notable growth in response to deregulatory events that reduce Title II requirements. 相似文献
