Market‐based integration is not appropriate to the joint development of the southern African region; the region's political, technical and institutional immaturity requires instead loose, function‐based economic cooperation. This will also facilitate intraregional trade. Subregions in the meantime could progress to higher levels of integration: international experience has shown that successful integration is most likely when it takes place on the basis of ‘regions within regions’. Cooperative development of the subcontinent is likely to be best achieved through the ‘concentric circles’ approach to regional cooperation, in which a revised Southern African Customs Union‐Common Monetary Area forms the highly integrated core of a loose, function‐based cooperative arrangement covering the whole of southern Africa. 相似文献

This paper focuses on the fundamental changes in the management of state enterprises that are taking place in China. Specifically, we discuss the expansion of enterprise autonomy and changes in the managerial decision-making structure. The genesis of the reform programme is traced back to inefficiencies caused by the over-centralized state planning system which reduced enterprise management to little more than an administrative function dominated by the Party secretary. As a consequence, managerial and technical cadres became demoralized and the growth of staff functions such as accounting, marketing and personnel management was stunted. From a series of experiments launched in 1978 has grown the realization that tinkering around with the state planning apparatus is insufficient to stimulate entrepreneurship and vigorous industrial expansion. Accordingly, reform has been launched on a broad front both within the state apparatus, in an endeavour to roll back external constraints on enterprise, and within the enterprise itself, by seeking to provide powerful incentives both to managerial cadres and workers through a system stressing individual responsibility and rewards commensurate with results. A number of severe constraints on the reform programme are analysed, in particular, the changing balance of power within the enterprise between the factory director, the Party secretary, the workers’congress and the trade union. Contradictions exist within the new structure of decision-making but, given a period of political stability and sustained economic growth, there should be sufficient surplus to mollify discontent and stifle those who refuse to give up their belief in the virtues of having‘politics in command’of the industrial enterprise. 相似文献

Frictions, Heterogeneity and Optimality in Mortgage Modeling 总被引:1,自引:0,他引:1
The purpose of this article is to provide a unified framework for incorporating frictions into a theoretical options-pricing model (OPM) for mortgages. This article presents formulation for a frictions-adjustable mortgage model that integrates borrower heterogeneity while simultaneously preserving prepayment and default financial decisions. Our model demonstrates the flexibility of the OPM by simulating separate and concurrent effects of three categories of frictions on the mortgage and mortgage components. Researchers can use our example formulation to determine the effects of specific borrower characteristics on mortgage values without destroying the options theoretic framework. 相似文献

An estimated 12.6% of primary mortgage loans were simultaneously originated with a second loan from 2004 until 2008, although relatively little is known about how the presence of such subordinate loans affects the default decisions of borrowers. We use a novel data series of loan servicing records from 2002 until 2010 to identify such borrowers and find evidence that the default behavior of these borrowers significantly differs from borrowers without second loans. Estimating a discrete‐time proportional odds hazard model, we find borrowers with a second loan were 62.7% more likely to default each month on their primary loan when conditioning alone on the attributes of the primary loan. However, borrowers of second loans were 58.3% less likely to default on their primary loan as compared to single‐loan borrowers with equivalent current combined attributes (i.e., loan‐to‐value, balance and interest rate). We hypothesize and provide empirical evidence that this occurs because borrowers with second loans have the option to sequentially default on each loan since subordinate lenders will not pursue foreclosure if borrowers have insufficient equity. Lenders of defaulted subordinate debt may revisit their decision to foreclose in the future after housing markets start to recover, thus prompting a new round of foreclosures. 相似文献

The timing of prepayment: A theoretical analysis 总被引:1,自引:0,他引:1
This article develops the analytical methods necessary to determine the prepayment patterns of a mortgage contract. The most obvious measure of how many years a mortgage is likely to last is the expected time to termination. It is this measure that we most fully explore. However, since the method employed is able to characterize the probability of prepayment in any given time period, the means is provided to determine any measure of the time to termination. 相似文献

Waiting to Default: The Value of Delay 总被引:3,自引:0,他引:3
This paper analyzes the opportunity for early termination of a mortgage contract. We consider the possibility of defaulting on the property and explore the rules that are used by a value-maximizing borrower in exercising this option to default. The discussion centers on the value of waiting to make such a decision and the consequences of this rational inertia. We show that the observed delay in default usually attributed to transaction costs can instead be explained as entirely rational choice in a dynamic environment. 相似文献

This study investigates the structural shifts in urban population density gradients by first using the shifting regression technique of Farley, Hinich, and McGuire to detect the possible change in the structure of an urban area. Secondly, a generalized random coefficient technique is used to simultaneously detect the possible structural change and stochastic behavior of density gradients. Data for 50 United States SMSA's are used to do the empirical analyses. 相似文献

The dynamics of the unobservable short rate are frequently estimateddirectly using a proxy. We examine the biases resulting fromthis practice (the 'proxy problem'). Analytic results show thatthe proxy problem is not economically significant for single-factoraffine models. In the two-factor affine model of Longstaff andSchwartz (1992), the proxy problem is only economically significantfor pricing discount bonds with maturities of more than fiveyears. We also describe two different numerical procedures forassessing the magnitude of the proxy problem in a general interestrate model. When applied to a nonlinear single-factor model,they suggest that the proxy problem can be economically significant. 相似文献
