SCREENING AS A UNIFIED THEORY OF DELINQUENCY,RENEGOTIATION, AND BANKRUPTCY

We propose a parsimonious model with adverse selection where delinquency, renegotiation, and bankruptcy all occur in equilibrium as a result of a simple screening mechanism. A borrower has private information about her endowment, and a lender uses random contracts to screen different types of borrowers. In equilibrium, some borrowers choose not to repay and thus become delinquent. The lender renegotiates with some delinquent borrowers. In the absence of renegotiation, delinquency leads to bankruptcy. Applied to mortgage restructuring, our mechanism generates amplification of house‐price shocks through foreclosure spillovers. We also show that government intervention aimed at limiting foreclosures may have unintended consequences.     

Examining the association of smoking with work productivity and associated costs in Japan

Aims: Smoking is associated with significant health and economic burden globally, including an increased risk of many leading causes of mortality and significant impairments in work productivity. This burden is attenuated by successful tobacco cessation, including reduced risk of disease and improved productivity. The current study aimed to show the benefits of smoking cessation for workplace productivity and decreased costs associated with loss of work impairment.

Materials and methods: The data source was the 2011 Japan National Health and Wellness Survey (n?=?30,000). Respondents aged 20–64 were used in the analyses (n?=?23,738) and were categorized into: current smokers, former smokers, and never smokers. Generalized linear models controlling for demographics and health characteristics examined the relationship of smoking status with the Work Productivity and Activity Impairment questionnaire (WPAI-GH) endpoints, as well as estimated indirect costs.

Results: Current smokers reported the greatest overall work impairment, including absenteeism (i.e. work time missed) and presenteeism (i.e. impairment while at work); however, after controlling for covariates, there were no significant differences between former smokers and never smokers on overall work impairment. Current smokers and former smokers had greater activity impairment (i.e. impairment in daily activities) than never smokers. Current smokers reported the highest indirect costs (i.e. costs associated with work impairment); however, after controlling for covariates, there were no significant differences between former smokers and never smokers on indirect costs.

Limitations and conclusions: Smoking exerts a large health and economic burden; however, smoking cessation attenuates this burden. The current study provides important further evidence of this association, with former smokers appearing statistically indistinguishable from never smokers in terms of work productivity loss and associated indirect costs among a large representative sample of Japanese workers. This report highlights the workplace benefits of smoking cessation across productivity markers and cost-savings.

A nearly optimal auction for an uninformed seller

This paper describes a nearly optimal auction mechanism that does not require previous knowledge of the distribution of values of potential buyers. The mechanism we propose builds on the new literature on the elicitation of information from experts. We extend the latter to the case where the secret information shared by the experts–potential buyers in our model–can be used against them if it becomes public knowledge.     

Extended Producer Responsibility and the Evolution of Sustainable Specializations: Evidences From the e‐Waste Sector

Extended producer responsibility (EPR) is an environmental policy approach that could potentially have a positive impact on different determinants of the business environment, including scientific production. Despite that, direct and indirect impacts on those national research environments where EPR is not directly implemented are under‐represented in the current literature. Based on a dataset of 411 papers related to e‐waste published in the period between 2001 and 2011, our study explores the research dynamics of the e‐waste literature and presents a map of the main areas of interest. Two representations of the geographical time frames of research depict the on‐going reshaping of worldwide technical specializations and inform policy makers on the evolution of regional needs and competences. The conclusions highlight the importance of worldwide impact assessments of EPR in order to achieve both industrial and environmental goals.

Fiscal disparity and equalisation in the Russian Federation

The regions of the Russian Federation are economically disparate. Differential endowment with energy resources drives much of this disparity and this translates into highly diverse fiscal capacities. Although regions do have some independent revenue-raising authority, all taxes are administered by the national Ministry of Taxation and a sizable share (roughly 45%) of total national revenue is transferred to regional and local government. The transfers, however, are not of equal importance to all regions. This article focuses on vertical and horizontal balance in the country. It examines differential revenue capacity and the extent to which national transfer programmes mitigate fiscal disparity.     

The gift of being chosen

We report evidence from an experiment where an employer selects one of two workers to perform a task for a fixed compensation. Workers differ in their ability. The employer’s payoff depends on the worker’s ability and on a non-contractible effort that the worker exerts once employed. We find that selected workers exert an effort higher than the minimum enforceable one. When the employers can send a free-text form message to the selected worker, workers with low ability exert significantly higher effort than the workers with high ability. The difference in effort overcompensates the difference in ability.     

Does foreign ownership matter?

The paper both compares productivity of Russian firms that have foreign direct investments with productivity of fully domestically owned firms and analyses spillovers from foreign‐owned firms to domestic firms. Foreign firms are found to be more productive than domestic ones, but productivity of the former is negatively affected by slow progress of reforms in the regions where they operate. It is also found that there are positive spillovers from foreign‐owned firms to domestic firms in the same industry, but negative effects on domestic firms that are vertically related to foreign‐owned firms. The stock of human capital in regions where foreign firms operate is one of the factors which help domestic firms to benefit from the entry of foreign firms.     

The changing composition of academic majors and wage dynamics: Beyond mean returns

This paper studies the effects of the changing composition of academic majors during expansion of higher education on the dynamics of wage distribution. Using a unique dataset constructed from open-ended responses in the Russia Longitudinal Monitoring Survey, we conduct a structural analysis of wage distribution dynamics for higher education graduates over 2002–2016. In addition to the standard mean wage estimations across majors we explore within-major and across-cohort variation, as well as major-specific permanent and transitory variance components and their time paths.The results suggest that changing wage inequality among university graduates is due to both changes in skill prices and wage shocks induced by economic fluctuations. Moreover, variation in skill prices relates to equilibrium effects induced by changes in the supply of graduates specialized in different fields. Uneven expansion in certain majors induces labor market saturation and leads to an increase in the wage variance of graduates from the fastest growing majors. The estimation results also show the importance of accounting for within-major heterogeneity across cohorts, which could reflect differences in student ability distribution, changes in academic content, and changes in educational quality over time. Finally, this study suggests that focusing only on mean wage returns, without assessing the distributional implications, might substantially understate the labor market impact of the changing major composition.     

Approximate value-at-risk calculation for heterogeneous loan portfolios: Possible enhancements of the Basel II methodology

This paper presents three possible methods by which the credit value at risk estimates coming from the Basel II IRB approach can be significantly improved upon. The feasibility of the suggested approaches is substantiated by applying it to an exemplary model portfolio.
