On a control chart for the Gini index with simulations

In this work we suggest the use of the Gini index on control charts. The asymptotic properties of Gini index are presented and the control charts based on appropriate confidence intervals are constructed. The suitability of the proposed charts are investigated by means of extensive simulations.     

Non-tariff barrier on chicken imports into Russia: Impact on production,trade and prices

We analyze the Russian restriction on chicken imports as an example of a non-tariff barrier (NTB). Cointegration test results support the hypothesis that the NTB limited trade. We calibrate an equilibrium market model to cointegration results to assess the market impact. The tariff equivalent of the Russian chicken NTB is estimated to be 30 − 40% depending on the representation of consumer demand. Removing the NTB decreases domestic production by 4–5% and domestic price by 27%–34%, while imports increase by 326–423 thousand tons annually in 2015–2019.     

Parimutuel betting on the eSports duels: Evidence of the reverse favourite-longshot bias

We analyse betting behaviour patterns of the visitors of the specialized betting website dedicated to the popular eSports game Counter-Strike: Global Offensive. The reverse favourite-longshot bias is found, which is rather unusual for parimutuel betting markets, where favourite-longshot bias is more common. We define simple betting strategies based on the bets on underdogs and show that these strategies make a sufficiently large positive profit both on the in-sample and out-of-sample datasets, which is a sign of market inefficiency. In matches with popular underdogs, the sentiment bias decreases the market inefficiency caused by the reverse favourite-longshot bias. At the same time, the role of the geographical location of teams in the reverse favourite-longshot bias is only marginal.     

Technology as a Weapon in Domestic Violence: Responding to Digital Coercive Control

ABSTRACT

Technology-facilitated domestic violence is an emerging issue for social workers and other service providers. The concept of Digital Coercive Control (DCC) is introduced to highlight the particular nature and impacts of technology-facilitated abuse in the context of domestic violence. While practitioners have become more adept at working with women experiencing DCC, there is still little known about its dynamics and whether this violence requires a change in current service responses. This article explores findings from survey research conducted with 546 Australian domestic violence practitioners about the ways perpetrators use technology as part of their abuse tactics. The findings demonstrate that DV practitioners believe perpetrator use of technology is extensive and has significant impacts on the safety of clients. A major dilemma faced by practitioners is how to promote and facilitate client safety from DCC while still enabling safe use of technology so clients can remain connected to family, friends, and community.

IMPLICATIONS

• The use of digital technology in domestic violence creates a significant practice issue for Australian domestic violence practitioners.

• The development of a practice framework for responding to digital coercive control may assist practitioners to highlight the risks posed by this abuse, while still enabling women and children the freedom to participate in the digital realm.

     

习近平外交思想指向下中日关系发展的新定位

近年来中日关系逐步转寒回暖,无论政治交流氛围,还是经济合作环境都得到了较大改善,这离不开中国政府根据国际形势及中日关系的变化及时调整对日政策,也充分体现了习近平新时代中国特色社会主义外交思想对中日关系缓和发展的引领作用。在安倍首相访华及习近平主席出席大阪G20峰会之后,两国政府在努力建设契合新时代要求的中日关系上达成多点共识。中日双方将依托“一带一路”倡议和第三方市场合作的平台,进一步致力于深化经济合作,维护多边主义和自由贸易体制,共同培育新动能和新的增长点,加速东北亚区域命运共同体的构建。     

Response strategy to environment context factors using a lean and agile approach: Implications for firm performance

Based on the environment-strategy performance perspective and dynamic capabilities framework, we develop a theoretical model and hypotheses specifying how supply chain collaboration as a response to environment context factors – competitive intensity, supply uncertainty, technological turbulence and market turbulence, using a lean and agile strategy may influence firm performance. We test the model using partial least square structural equation modelling on data collected from a field survey with responses from 152 manufacturing firms representing a variety of industries. Empirical findings generally support the relationship between collaboration and firm performance using a lean and agile strategy. Also, for firms in industries that face environments characterised by high supply uncertainty and competitive intensity with, technological turbulence, the study finds evidence of a direct relationship between these environmental factors and supply chain collaboration. The findings provide an initial strategic response framework for appropriately aligning a lean and agile supply chain strategy through collaboration with environment context factors to achieve firm performance improvements.     

市场经济下政府与市场的关系

在市场经济中，市场必须在资源配置中发挥基础性或决定性的作用，但政府在市场失灵的地方又必须积极地发挥作用。本文分别从早期市场经济中政府的作用、现代市场经济中政府的作用等五个方面对这一问题进行论述。     

A neuroeconomic theory of (dis) honesty

We develop a theory of dishonesty based on neurophysiological evidence that supports the idea of a two-step process in the decision to cheat. Formally, decisions can be processed vía a costless “honest” channel that generates truthful behavior or vía a costly “dishonest” channel that requires attentional resources to trade-off costs and benefits of cheating. In the first step, a decision between these two channels is made based on ex-ante information regarding the expected benefits of cheating. In the second step, decisions are based on the channel that has been selected and, when applicable, the realized benefit of cheating. The model makes novel predictions relative to existing behavioral theories. First, adding external complexity to the decision-making problem (e.g., in the form of multi-tasking) deprives the individual from attentional resources and consequently decreases the propensity to engage in dishonest behavior. Second, higher expectations about the benefits of cheating results in a higher frequency of trial-by-trial cheating for any realized benefit level. Third, multiplicity of equilibria (characterized by different levels of cheating) emerges naturally in the context of illegal markets, in which expected benefits are endogenous.
