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 slow and endogenous twist of economic macro-structure makes up an important evolutionary feature of capitalist economies,
and may be at the root of structural crisis. In this line, a Goodwinian growth model with increasing returns and profit-sharing
that tries to picture a simple scenario of the seventies crisis is considered. It is shown that the exhaustion of the Kaldor-Verdoorn
“productivity law” can entail, in a nonlinear framework, a “catastrophic” bifurcation from a “high” to a “low” growth path.
Slow/fast dynamical systems then allow one to formalize a multiple time-scales dynamics where the growth path is shaped by
the structural framework in which it takes place, but has also a long -un feedback. Structural change and crisis appear as
long term and endogenous outcomes. 相似文献

ABSTRACTThe conservation enterprise is embedded in ideas of the environment through which it promotes a vision of the world and the relations between the non-human and human. The papers in this forum analyse conservation from various vantage points to draw the links between geopolitics and conservation. The authors use three themes to demonstrate these links. The first theme draws on the concept of environmentality to show the mobilization of ecological rationalities and power towards the creation of protected areas. The second pays attention to networks formed across the distance, and how they influence the location and governance of protected areas. The third focuses on the strategies the conservation lobby uses to align local identities with global conservation ideals and goals. Collectively, these themes highlight features of conservation geopolitics. 相似文献

This paper aims to identify the moderating effect of service firms’ adoption of market orientation on key variables of consumer behavior, namely perceived value and loyalty. The study took a business-to-customer perspective. First, the adoption of market orientation was measured, from the firm’s point of view. Second, customer perceptions were analyzed, using the two variables perceived value and loyalty. The sample comprised 100 service firms and 572 of their customers. The present work provides original insights, identifying that the effect of perceived value on loyalty depends on other variables external to the consumer, such as the market orientation approach. 相似文献

The bidirectional causal links between high-skilled emigration and poverty can give rise to multiple equilibria and coordination
failures. Two countries sharing identical characteristics may end up in either a “low poverty-low brain drain” equilibrium
or in a “high poverty-high brain drain” equilibrium. In this paper, we build a model which endogenizes high-skilled emigration
and economic performances in order to derive the conditions under which multiplicity occurs. After identifying country-specific
parameters, we find that in the majority of developing countries, the best equilibrium is selected and that the observed brain
drain is inevitable. In 22 small developing countries however, the worse equilibrium prevails, implying that poverty and brain
drain are increased by coordination failure. These countries require appropriate development policies, such as a temporary
subsidization of the repatriation of their high-skilled expatriates. Our results are robust to the inclusion of a brain gain
mechanism. 相似文献

At the center of the on-going debate about the U.S. Social Security system is the question of whether the way the system is financed can cope with the future challenges posed by the retiring Baby Boom generation. The "reformers" suggest changing the design of the system by moving to fully funded defined contribution retirement plans. Others argue that the so-called demographic problems are being used as an excuse to privatize the system. But both sides spend almost all of their energy and time figuring out the timing of insolvency of the system and the validity of the assumptions made in each forecast. In contrast, the present study closely examines the changing macroeconomic dynamics of the system since the 1960s. The analysis shows that undermining of the system is caused not by demographic changes or financing mechanisms but by low wages and medical inflation. 相似文献

Those economists who expected the increasing US budget deficits in recent years to have a negative impact on private investment spending have so far been proved wrong. Hans-Peter Fröhlich provides an analysis of what has happened and examines the interrelation between public sector deficits and private capital expenditures. 相似文献

This paper considers an economy with heterogeneous workers where identical firms optimally decide on the degree of complexity of jobs. Meetings are depicted by an urn-ball process where firms rank their applicants and pick the best one. We show that a general rise in unemployment induces an increase in the employment shares of high-skilled workers which, in turn, makes firms choose more complex jobs, leading then to a decrease in the output of low-skilled workers. The technical skill bias is therefore related to the usual explanations of unemployment. Next, we state that a decentralized equilibrium is efficient in terms of job complexity but inefficient in terms of job creation when firms internalize the usual congestion effect. We then extend the analysis to a dynamic model. 相似文献

Corporate Social Disclosure in the Franchising Sector: Insights from French Franchisors’ Websites 下载免费PDF全文
Frédérique Déjean 《Journal of Small Business Management》2015,53(2):321-339
This paper explores corporate social responsibility (CSR) within the franchising sector. More specifically, using regulation theory, stakeholder–agency theory, transaction cost analysis, and literature on plural form, along with an empirical study conducted on the franchising sector in the French market, we find significant and positive relationships between chain size and the extent of corporate social disclosure (CSD) on franchisors’ websites and between the percentage of company‐owned units within the chain and the extent of CSD on franchisors’ websites. Moreover, though findings reveal that 86.03 percent of the 136 sampled franchisors communicate about at least one of their CSR activities on their websites, differences in terms of highlighted categories (e.g., environment, human resources, and products) and the extent of available CSR information exist. 相似文献
