The question this paper investigates is whether or not different metropolitan areas each constitute a separate housing market or whether or not there is a single South African housing market. Theory on the Law of One Price suggests that if products or geographic areas belong in the same market, their absolute prices must converge, so that their relative prices are stationary. By using cross-sectional time series data of five metropolitan areas, the paper tests for the Law of One Price by applying the Im, Pesaran and Shin panel unit root test. The paper finds strong evidence of convergence in large middle-segment house prices and weaker support for convergence in medium middle-segment house prices. In addition, the paper finds no evidence for convergence in small middle-segment house prices. This suggests the existence of a national market for large and possibly middle-segment houses in metropolitan areas, but separate metropolitan markets for small middle-segment houses. In addition, the paper estimates the speed of convergence and finds that large middle-segment house prices converge within two to seven quarters, while the speed of convergence for medium middle-segment house prices in three of the five areas is five to eight quarters. 相似文献

Summary Competition authorities are increasingly measuring the effects of their enforcement actions, seeking a robust justification
for the proliferation of competition policy. We highlight the importance of identifying the right counterfactual against which
to measure effects, and set out the relevant categories of costs and benefits. We then explore how a balance can be struck
between the benefits and inherent limitations of these measurement exercises. Relatively crude analyses of cartel action benefits
can be sufficient to achieve public legitimacy for competition policy. Assessing the effects of merger and conduct inquiries
is often ambiguous, but could be used to improve decision-making processes.

Infrastructural and societal changes intertwine in multiple ways. This makes the societal implications of infrastructural projects difficult to assess and anticipate. Yet in present day network societies this task is particularly urgent. This paper first identifies two positions that tend to monopolize and deadlock debates. Next it examines two decades of research in the Large Technical System (LTS) research field for alternative approaches to this issue, before finally suggesting distinguishing between the four increasingly indirect moments of (co-) construction of infrastructures and societies. These may be related causally, but also add their own moments of contingency, agency, and choice. 相似文献

Many firms are experimenting with how to standardize new technologies. They may use proprietary technologies for their products and services, and let them compete in the market selection. Alternatively, they can cooperate to jointly set a standard and experiment with combinations of market process and cooperation. If firms let the market decide, they can compete with technologies and need not invest time and effort in hammering out a standard. If they do incur the costs of negotiated standardization, they may enable end users to realize the benefits of standards. A hybrid standardization process combines the advantages of both market selection and negotiated decision making. This paper presents a contingency framework to identify conditions that will affect the preferred standardization process for vendors who introduce new technologies. A major contingency that this paper points to is the systemic nature of technologies in information and communication technology industries. The more systemic the technology is (in a way to be clarified), the less likely that firms will establish a hybrid standardization process. One advantage of decomposing technology systems in smaller components (modules) is that this approach enables firms to combine market selection with negotiated selection of standards. 相似文献

This paper investigates whether governments can change market structures through interventions. We study the effects of four political events over the life cycle of the market for daily newspapers in the Netherlands. We find that policy measures meant to lower entry barriers in an expanding industry created new entry and increased survival chances for potential entrants and incumbent newspapers. Exit barrier enhancing policies to reduce concentration tendencies have not been successful. 相似文献

This paper discusses the impact of a redistribution of current income from the White to the Black population on the distribution of sectoral output, and total employment by means of a semi‐closed input‐output model.
The results show that a redistribution of current income towards Black households — which no doubt will have positive social and political repercussions — has a non‐negative effect on GDP and a definite positive effect on the performance of sectors with a high private consumption expenditure component, as well as on total employment. 相似文献
