WHAT AFFECTS EFFICIENCY IN LABOUR MARKET MATCHING AT DIFFERENT TERRITORIAL AGGREGATION LEVELS IN POLAND?

We analyse efficiency of a labour market matching process at different levels of territorial aggregation and in different time horizons. We apply a stochastic matching frontier to random, job queuing and stock‐flow models. We use data for Poland, a country with highly regionally diversified unemployment. We find that search and matching mechanisms significantly differ with territorial aggregation. Higher efficiency in small regions results from lower frictions. Larger regions enjoy better structural matching if only labour market participants have time to search. Different policy measures should be designed to improve labour market matching efficiency at different regional levels.     

Customers’ intention to adopt smart lockers in last-mile delivery service: A multi-theory perspective

Many logistics service providers are now adjusting their business service strategies to satisfy consumers' higher demands and expectations. An automated parcel locker for self-pickup is one of the options; however, there is currently no smart locker service available in Thailand. This study integrates resource matching theory, innovation diffusion theory, and theory of planned behavior to clarify Thai consumers' intention to utilize smart lockers. The data for this study were received from 302 participants living in Thailand. Convenience, reliability, privacy security, compatibility, relative advantage, complexity, perceived behavioral control, and attitude were included in the questionnaire to test if they were significant determinants of consumers' intention to use smart lockers. The results reveal that convenience, reliability, privacy security, compatibility, relative advantage, complexity, perceived behavioral control, and attitude influence Thai consumers’ intention to use smart lockers. This study contributes to the literature on combining resource matching theory, innovation diffusion theory, and theory of planned behavior; this enriches theoretical research on self-service technologies in last-mile logistics delivery, and also provides insights for consumer behavioral research.     

A re-examination of accruals quality following restatements

Empirical research from the first years following the Sarbanes-Oxley Act (SOX) in the US suggests that firms improve accruals quality following restatements, but the materiality of restatements has declined since then. This decline may affect firms' responses to restatements, and hence we re-examine whether restatements are associated with subsequent improvements in accruals quality in a more recent sample. We compare the changes in accruals quality of firms restating between 2000 and 2014 with that of a control group. We do not find that firms improve accruals quality more than the control group following a restatement, even when we isolate the types of restatements considered to be most material. However, we do find that restatements followed by the most negative stock market reactions are associated with a relative increase in accruals quality, indicating that only restatements deemed very severe by investors lead to subsequent improvements in accruals quality. Our results suggest that firms' responses to restatements have changed concurrently with the trend of fewer and less material restatements in recent years.

Mathematical foundation of the replicating portfolio approach

In the last few years, the first theoretical foundations for replicating portfolios – probably the most prevailing technique for risk capital calculation in life insurance – have been given in a series of papers by Beutner, Pelsser and Schweizer. In these papers, the asymptotic behaviour of replicating portfolios concerning the approximation of the terminal value (TVL) and the fair value distribution of the liabilities (FVL) has been investigated in detail. We complement this line of research by providing results on approximations based on a finite number of replicating instruments. We do so by providing the link between the approximation error of the TVL distribution, the FVL distribution and the error in the resulting risk capital figure, either value at risk or some coherent risk measure. We further allow for a variety of practically relevant formulations of the replication problem, including cash flow matching approaches. In contrast to the existing literature, all our results apply to approaches both under the risk-neutral and the real-world measure. Our strongest bounds are due to the observation that in discrete time, the measure change from the real-world to the risk-neutral measure can be both bounded below and above by a suitable constant in the first period.     

工会的“收入溢价”效应研究——基于中国流动人口动态监测数据的分析

基于中国流动人口动态监测数据（2014）,实证分析流动人口工会的“收入溢价”效应。研究发现：工会能显著提升流动人口的收入,但工会的“收入溢价”效应具有异质性,城城流动人口高于乡城流动人口、签订合同者高于未签订合同者,个体私营企业的表现要优于国有集体企业和外资企业;分位数回归结果显示,随着分位数水平的上升,流动人口工会的收入效应呈倒“U”型,对中等收入者的作用最大,其次是低收入者,对高收入者的作用最小;采用倾向得分匹配法解决自选择问题,发现我国流动人口仍存在明显的工会“收入溢价”效应。     

Peer Effects in Consumption Among Chinese Rural Households

This article attempts to identify peer effects in household consumption in rural China using the Chinese Household Finance Survey (CHFS) 2011 data. In addition to the selection effect, reflection problem and correlated effect, we address the actual peer problem via the matching method in identifying the peer effect. It is found that as peer household’s consumption expenditure increases by 1%, the household’s consumption would increase by 0.24%. It is also found that richer households are more susceptible to peer pressure in consumption decisions. Finally, household is more sensitive to changes in the consumption of poorer peers, relative to their richer peers.     

The national innovation policy effect according to firm location

The regional nature of innovation and innovation policy was investigated. The aim of this study was to determine whether the specific economic and institutional conditions of a region had an influence on the results of a national policy intended to support entrepreneurial innovation. The analysis compared the effect of the national R&D subsidies on the innovation effort of firms located in central regions, which concentrate an important percentage of the national innovation activity, together with those firms located in periphery regions. Significant regional differences were detected with regard to the national R&D subsidies’ effect and distribution. The central regions manifested a higher subsidy effect compared to the periphery regions. The results of this study have allowed us to conclude that the region plays an important differentiating role in connection with the final result of the innovation policy aimed at the entire national territory. Therefore, this study recommends including the geographical location of the firm in future evaluations.     

Disentangling Treatment Effects of Active Labor Market Policies: The Role of Labor Force Status Sequences

This paper estimates treatment effects of two active labor market policies – a training program and a wage subsidy scheme – on participants' employment probabilities. The analysis is based on unique data from the 18th wave of the Polish Labor Force Survey containing detailed and extensive individual labor force status histories. We discuss two variants of an exact covariate matching procedure adapted to the specific nature of the data. Our study confirms and reinforces a point raised in recent research [Heckman, J.J., Smith, J.A. The Pre-programme Earnings Dip and the Determinants of Participation in a Social Programme: Implications for Simple Programme Evaluation Strategies. The Economic Journal 1999; 109; 313-348., Heckman, J.J., Smith, J.A. The Determinants of Participation in a Social Program: Evidence from a Prototypical Job Training Program. Journal of Labor Economics 2004; 22; 243-298.], that pre-treatment labor force status dynamics play a decisive role in determining program participation. We implement a conditional difference-in-differences estimator of treatment effects based on these individual trinomial sequences of pre-treatment labor market status. The estimator employs a “moving window” technique that nicely controls for changes in the macroeconomic environment over time. Our findings suggest that training raises individual employment probability, while wage subsidies display negative treatment effects for participants in the Polish case.
