A multilevel framework to enhance organizational resilience

Abstract

Organizational resilience is a capacity that emerges at multiple levels. Although the multilevel character of organizations has been generally acknowledged in existing organizational studies, there is a lack of theoretical and empirical studies that address how it affects organizational resilience. To adress this gap, this article offers a multilevel framework applicable to enhance organizational resilience and presents an empirical study to probe the impact of multilevel elements on organization's capacity for responding to critical situations. More specifically, the new framework will help an organization to enhance its resilience through a process of self-assessment on crisis preparedness and response capacity. This process will allow the organization to identify and remedy potential vulnerabilities in the interaction between its organs as well as environment. We argue that crisis management and organizational resilience are mutually shaped across multiple levels, from individual, organizational, to environmental. These multiple levels are operationalized operationalization in four phases: (1) reviewing and monitoring context, (2) testing preparedness, (3) analysing and assessing responses, and (4) strengthening capabilities. In these phases, we underline that resilience management requires continuous embracing of the dynamic processes within an organizational system and its environment. To validate the framework, we present an empirical study on a security organization, and describe the results to demonstrate how to utilise the tool in practice. In conclusion, we discuss how the multilevel framework can be further applied towards building stronger resilience management.     

Cost analysis of road traffic crashes in China

Abstract

Fatalities and injuries resulting from road traffic crashes is always a serious problem. The overall economic losses caused by road traffic crashes are beyond imagination. Including the economic cost of property damage, productivity loss, medical cost, travel delay time cost, legal cost and insurance cost, the total economic cost of traffic crashes in China in 2017 is calculated as 490.1 billion yuan (72.6 billion USD 2017), which is equivalent to 0.60% of the GDP. The cost of productivity loss accounts for the highest proportion of total economic cost, which is 72%. The second is the travel delay cost, accounting for 12% insurance cost, property damage cost and medical cost are followed. The more serious the injury, the higher the unit economic cost. The unit cost of a crash that caused only property damage is 11,274 yuan. The unit cost of a minor injured crash is 20,223 yuan. The highest unit economic cost is the unit cost of a fatal crash, which is 3,181,394 yuan. This study provides important insights into the cost-benefit analysis of China's road safety policies.     

Do investors value companies' mandatory nonfinancial risk disclosure? An empirical analysis of the Italian context after the EU Directive

In October 2014, the European Union adopted Directive 2014/95/EU (hereafter, EU Directive), mandating companies of a certain size to draft and publish corporate nonfinancial information (NFI) regarding society and the environment. In this study, we examine the mandatory disclosure of nonfinancial (NF) risks by listed Italian companies, as required by the EU Directive, focusing on both the state‐of‐the‐art of such disclosure and its usefulness for investors. For this purpose, the study adopts a two‐staged research approach; in the first stage, we employed a manual meaning‐oriented content analysis to investigate the NF declarations (NFDs) of the listed Italian companies that were obliged to disclose NFI, returning a quality NF risks disclosure index. In the second stage, we used the value relevance methodology to investigate whether the disclosed NF risk information affects the levels of equity prices, through a modified Ohlson model. Our research is one of the first to investigate the value relevance of mandatory disclosures of NF risks following the implementation of the EU Directive, in the Italian context. The research was carried out in 2017, the first year of the directive's application for listed Italian companies. The main findings support a positive association between NF risk information disclosure levels and companies' market value. Moreover, they provide evidence of a significant mediating effect of NF risk on the relationship between financial risks and market value.     

Environmental R&D and privatization in a mixed duopoly market

The study examines strategic environmental research and development (ER&D) under environmental tax in a mixed duopoly and further analyzes the impact of privatization on it. We show that the environmental tax may not necessarily promote the private (or public) firm's ER&D, and the relative ER&D performance between firms depends on the public firm's environmental attitudes and the tax rate. When the public firm cares much for environment, it can be used as an instrument to correct the private firm's underinvestment (or overinvestment) in ER&D. Moreover, privatization can (cannot) raise both firms' ER&D simultaneously if the tax rate is high (low).     

Backing what works? Social Impact Bonds and evidence-informed policy and practice

ABSTRACT

Social Impact Bonds (SIBs) offer an opportunity to explore the use of evidence to inform public policy and commissioning decisions in both discursive and practical terms in what are frequently highly politicized contexts. We identify three potential mechanisms by which SIBs may promote evidence use and explore these through empirical findings drawn from a three-year evaluation of SIBs applied to health and social care in the English NHS.     

产业政策对企业间工资差距的影响—来自中国工业企业的经验证据

中国产业政策的执行对企业间工资差距有何影响?文章首先考虑加入了产业政策因素的异质性企业模型,从理论上将产业政策对企业工资影响分解为补贴转移效应与竞争效应两种机制,并提出如下假说:企业将部分政策补助用于生产,此时支付的更多工资等同于财政的直接补贴;同时,企业工资水平也取决于企业的生产效率,产业政策通过促进或抑制行业竞争改变企业效率,从而对企业的工资水平产生一种间接影响,即竞争效应.使用1998?2007年中国工业规模以上企业数据对理论假说进行实证检验,可以发现:"中国式"产业政策抑制企业效率带来的负向竞争效应超过了正向的补贴转移效应,最终造成了企业工资水平下降;然而,一旦产业政策的施行促进了行业竞争,竞争效应则为正,那么企业的工资水平也会随之提高.文章研究的结论有助于理解经济改革过程中产业政策对企业工资的影响,对推进企业工资体制改革也具有启示意义.     

Wage-vacancy contracts and coordination frictions

We consider a directed search model with risk-averse workers and risk-neutral entrepreneurs who can set up firms that post wage-vacancy contracts, i.e., contracts where firms can make payments to more than one applicant, and where the payments can be different for each applicant and be contingent on the number of applicants. We establish that the type of contracts the literature focuses on are not offered if firms can post wage-vacancy contracts. We show that there exists an equilibrium satisfying a Monotonic Expected Utility property which is efficient. Furthermore, we investigate the role of wage-vacancy contracts on welfare and competition.     

CEO turnover and bankrupt firms’ emergence

This paper examines whether CEO turnover within a bankrupt firm predicts the firm's likelihood to reemerge from bankruptcy proceedings as a reorganized entity. Using 836 bankruptcy cases filed under Chapter 11 of the United States Bankruptcy Code from 1989 through 2016, we show that firms that undergo CEO turnover are significantly more likely to emerge from Chapter 11 proceedings. We conduct further analyses to examine the potential mechanisms through which CEO turnover is linked to a firm's chance of emergence. Consistent with the perspective that CEO turnover constitutes an observable event that can signal creditor support, we find that CEO turnover in bankrupt firms is positively associated with debtor-in-possession financing. Additionally, there is a significant increase in managerial quality post-turnover. Further, we document that the predictive power of CEO turnover is stronger in bankruptcy cases with greater uncertainty, such as in free-fall bankruptcies, where there is less preexisting agreement between the firm and its creditors. Overall, our findings provide valuable insight into external investors and stakeholder groups, whose interests are significantly impacted by corporate bankruptcies.     

The Effects of Differential Income Replacement and Mortality on U.S. Social Security Redistribution

We study redistribution via the U.S. Social Security retirement system for cohorts of men born during the second half of the 20th century. Our focus is on redistribution across race and education groups. The cohorts we study are younger than cohorts studied in previous, similar research and thus more exposed to recent increases in earnings inequality. All else equal, this should increase the degree of progressivity of Social Security redistribution due to the structure of the benefit formula. However, we find that redistribution is only modestly progressive for individuals born as late as 1980. Differential mortality rates across race and education groups are the primary explanation. While Black–White mortality gaps have narrowed some in recent years, they remain large and dull progressivity. Mortality gaps by education level are also large and unlike the gaps by race, they are widening, which puts additional regressive pressure on Social Security redistribution.
