We compare the performance of a wide set of regression techniques and machine-learning algorithms for predicting recovery rates on non-performing loans, using a private database from a European debt collection agency. We find that rule-based algorithms such as Cubist, boosted trees, and random forests perform significantly better than other approaches. In addition to loan contract specificities, predictors that refer to the bank recovery process — prior to the portfolio’s sale to a debt collector — are also shown to enhance forecasting performance. These variables, derived from the time series of contacts to defaulted clients and client reimbursements to the bank, help all algorithms better identify debtors with different repayment ability and/or commitment, and in general those with different recovery potential.  相似文献

The standard account of Austrian Business Cycle theory posits that central bank manipulations of interest rates fool bankers and investors into believing that there has been an increase in the real supply of loanable funds available for capital investment. However, reliance on foolishness ignores the entrepreneurial emphasis within the Austrian tradition and fails to produce the strongest possible case for Austrian Business Cycle theory. We use the prisoner's dilemma framework to model the profit maximizing behavior of bankers and the investors under uncertainty when the market rate of interest is below the underlying rate of time preference.  相似文献

Michael Porter, the influential Harvard management guru, has promoted the idea that compliance with stricter environmental regulations can afford secondary benefits to firms through improved product design, innovation, corporate morale and in other ways. Once these secondary benefits are factored, the net cost of compliance is argued to be lower than conventionally thought and may even be negative. Whilst environmental economists have rejected the Porter Hypothesis as being based on excessively optimistic expectations of the likely size of such secondary benefits the underlying ideas do enjoy significant credence in the business community. In the context of a lobbying model of regulatory policy-making we argue that the EPA should change the way it conducts regulatory policy to take account of Porter's views – even if it knows those views to be misguided. The model serves to illustrate the more general point that fashions in management thinking can be expected to impact the optimal conduct of regulatory policy.  相似文献

In this paper we develop a framework to assess the economic impact of foreign investment projects. If investment projects interact with other industries in the host economy, either by buying inputs locally or by selling their own product to local downstream firms, they can create sectoral linkages. The expansion of upstream and downstream industries can feed back to the project's own industry leading to a further expansion of the local industry. We study the circumstances under which investment projects lead to the creation of sectoral linkages and characterize the factors that determine the project's welfare impact. We link analytical findings to case studies undertaken for the EBRD.  相似文献

A bstract Bills introduced in the 100th and 101st Congresses would amend the Sherman Act in regard to retail competition Their two key provisions would seek to (1) alter the standard of proof currently used for the establishment of illicit vertical price arrangements and (2) codify into law the judicially-established per se rule against resale price maintenance agreements The first provision seeks to overcome the effect of the establishment by the Supreme Court , in its Monsanto decision, of what is viewed as an illogical and impossible burden of proof on plantiffs seeking damages in resale price maintenance cases The second merely incorporates into statutory law the court's declarations in the Dr Miles case of the per se illegality of resale price maintenance agreements Arguments for and against this legislation are discussed and recent developments are examined  相似文献

Regulatory agencies are often legally obliged to use a cost-benefit rule in revising environmental standards to reflect improvements in pollution-control techniques, but have considerable discretion over the timing of such revision. How should the agency use this discretion? Longer lags tend to encourage more intense R&;D effort by the regulated industry itself whilst discouraging parallel effort by external developers. Optimal implementation lags are characterized. The analysis calls into question the conventional view that “footdragging” by agencies is necessarily evidence of incompetence or regulatory capture. More generally, whether or not subject to conscious manipulation by regulatory agencies, the delays routinely observed in implementation may enhance welfare.  相似文献

Abstract

Through an in-depth, multilevel case study of a professional services firm, this paper illuminates what stakeholders mean when they use the term ‘talent’. The paper underlines how various contextual factors including, workforce composition, ownership structures and individual perceptions influence talent meanings within an organisation. Our analysis of talent phenomena at a multiplicity of levels illustrates that it is not only about the words, phrases, and terms employed when talking about talent that requires examination. There is a need to deliberate on the meanings that underpin the talk because while stakeholders may talk the same way they may mean different things. The paper makes a key theoretical contribution through specific recognition of the importance of thoughtful reflection of how stakeholders discursively construct meanings because ‘talent’ is a concept, which requires translation via talk to become meaningful within the material world and these meanings are influenced by context. Thus, we cannot infer, that talent meanings radiate within organisations, nor across organisational boundaries, industries or countries because discourses arise and materialise within specific contexts and we must acknowledge that talent discourses can not be removed from the context in which they operate.  相似文献

Suppose a production function, f, is continuous, quasi-concave and weakly monotone on the non-negative orthant of Euclidean n-space. Let c(·, ·) be the associated cost function. Then it is shown that f is concave if and only if for each w, c(w, ·) is convex.  相似文献

We identify and analyse several dynamic implications of setting environmental standards such as to balance marginal costs and benefits. The adoption of such a regulatory approach is shown to effect (i) the speed of improvement of abatement technologies; (ii) the direction (in a sense to be defined) of that improvement; (iii) its source and the distribution of the rents from it; and (iv) the rate of development of defensive (averting) technologies. Existing views are thoroughly synthesised in the context of a simple diagrammatic model, several new results are derived and at least one conventional wisdom questioned. The message of the analysis for legislators and regulators is that cost–benefit balancing should be done with care.  相似文献
