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.     

俄罗斯产业结构现状

苏联解体后,俄罗斯的产业结构依然保持了苏联经济结构的基本格局和特点,而且其产业中轻重结构畸形和原材料化趋势还在发展,出现了自发性和退化性的反工业化趋势。俄罗斯产业结构具有以能源工业为支柱,军事工业与机械重工业为重点,民用工业严重落后的特点。应改革国家调控制度,降低通货膨胀和利率,发展抵押贷款信贷制度,加强立法,保障市场的有效运转。     

Solving the Winner Determination Problem in a Divisible-Object Auction

In an auction of a divisible object, bidders' demand functions are often assumed to be nonincreasing, meaning that bidders are willing to pay less or the same price for every additional unit. Under this assumption, the optimal allocation that maximizes the auctioneer's revenue can be found using a greedy-based procedure. This article argues that situations may arise where a bidder may need to express her preferences through a nondecreasing demand function; when such a bidder is present in the auction, the greedy-based procedure does not guarantee the optimal allocation. Thus, this article proposes a mixed integer program that finds the optimal allocation in a divisible-object auction at which bidders submit their bids as arbitrary stepwise demand functions. The practical aspect of the mathematical program is presented by means of a simple yet illustrative example in a treasury bond auction setting. The results of the auctioneer's revenue are reported as a function of the number of bidders with nonincreasing and nondecreasing demand functions.     

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.

Unconventional monetary policy and the dollar–euro exchange rate: further evidence from event studies

New evidence is presented on the impact on the US dollar–euro (USD–EUR) exchange rate of the unconventional monetary policy conducted by the US Federal Reserve (FED) and the European Central Bank (ECB). To that end, we employ an event study approach using daily the USD–EUR exchange rate for the period from 2 January 2007 to 31 January 2015. Our results indicate that the announcement and subsequent implementation of such measures by the ECB would have caused in general an appreciation of the dollar, while those by the FED would have caused a depreciation of the dollar.
