Use of Poset Theory with Big Datasets: A New Proposal Applied to the Analysis of Life Satisfaction in Italy

The aim of this work is to propose a tool for measuring a complex concept, and to apply it to big sets of data measured on ordinal and/or dichotomous scales. An important field of application are subjective data, that are often based on opinions or personal evaluations. Many national and international surveys employ this kind of data, measured among thousand of individuals. Thanks to the use of the “average rank” as a synthetic measure of a complex concept, we believe that poset theory could be a very useful approach for dealing with ordinal data avoiding the use of scaling procedures. Because classic poset approaches are at their best when applied to few data at a time, our idea is based on a procedure for sampling units from a big population using a simple criterion to summarize the resulting values appropriately. Applying the central limit theorem enables a comparison of the results obtained from different groups using statistical tests on the means. We used our Height of Groups by Sampling (HOGS) method to compare the average rank among groups that are defined by one or more socio-demographic variables influencing the level of the complex concept we wish to measure. The application of the HOGS procedure to life satisfaction in Italy generated convincing results, revealing significant differences between regions, genders and levels of formal education. We compared the results given by HOGS with the non linear principal component analysis and obtain an easy readable output with convincing precision and accuracy; we are confident that the HOGS procedure can be applied to many other concepts investigated in the social sciences.     

Estimating the Size of Street-Dwelling Populations Using Mark-Resighting Counts

Mark-resighting constitutes an advanced technology for estimating animal abundance. Joint hypergeometric maximum likelihood, Minta-Mangel and Bowden estimators are usually adopted with mark-resighting data. In presence of any tendency of animals to aggregate into groups, the Bowden estimator is the sole reliable method, providing that marks are quite evenly distributed among groups. In some cetacean surveys, marking disturbances are avoided through natural marking. Natural marking with Bowden criterion is used to estimate the abundance of street-dwelling populations. The marked individuals are persons identified and recorded in the initial part of the survey and recognizable in subsequent occasions. A simulation helps determine the performance of the Bowden estimator under a wide set of situations, taking into account key features of street-dwelling populations. When marked individuals are evenly distributed among groups, the strategy is efficient.     

Endogenous fertility,endogenous lifetime and economic growth: the role of child policies

We examine the effects of child policies on both transitional dynamics and long-term demo-economic outcomes in an overlapping-generations neoclassical growth model à la Chakraborty (J Econ Theory 116(1):119–137, 2004) extended with endogenous fertility under the assumption of weak altruism towards children. The government invests in public health, and an individual’s survival probability at the end of youth depends on health expenditure. We show that multiple development regimes can exist. However, poverty or prosperity does not necessarily depend on the initial conditions, since they are the result of how a child policy is designed. A child tax, for example, can be used effectively to enable those economies that were entrapped in poverty to prosper. There is also a long-term welfare-maximising level of the child tax. We show that a child tax can be used to increase capital accumulation, escape from poverty and maximise long-term welfare also when (a) a public pay-as-you-go pension system is in place and (b) the government issues an amount of public debt. Interestingly, there also exists a couple child tax–health tax that can be used to find the second-best optimum optimorum. In addition, we show that results are robust to the inclusion of decisions regarding the child quantity–quality trade-off under the assumption of impure altruism. In particular, there exists a threshold value of the child tax below (resp. above) which child quality spending is unaffordable (resp. affordable) and different scenarios are in existence.     

Managerial Delegation under Alternative Unionization Structures

This paper studies the effects of managerial delegation in a duopoly game under alternative unionization structures. Introducing managerial delegation in a framework with centralized unionization leads to incentives for sales, lower profits and higher consumer surplus as well as overall welfare. In contrast, delegating output decisions to managers in the presence of decentralized unionization produces opposite results unless unions are strongly employment‐oriented. Moreover, managerial delegation makes unionization structure neutral in relation to consumer surplus and overall efficiency. Finally, the timing of moves in the three‐stage game proves to be important for obtaining the above qualitative results under decentralized unionization.     

Firm internationalization and performance: Evidence for designing policies

The debate on the relationship between internationalization and performance is still open and is a hot topic for policymakers, but they ignore the impacts for most of the firms supported. The paper is based on a large database of seven years that considers quantitative-qualitative and control variables. To reduce industry and country heterogeneity we focused on the Italian automotive supply chain. We tested 5 modes of internationalization on firms’ profitability so to support the design of policies. Our results are partially in contrast with literature; therefore we identify specific environments where policies, namely for exporting, could be more effective.     

Social capital and innovation dynamics in district-based local systems

The idea behind this paper is that social capital (SC) is interpreted as a component of an investment, which implies entangled private and public benefits. Within a theoretical framework that considers SC as the public component of the impure public good R&D we show that the ‘civic culture’ of the district in which a firm is located is not a sufficient incentive for the firm to increase its investment in SC, because SC/networking dynamics might positively and complementarily evolve only if the opportunity cost of investing in innovation is sufficiently low. Consequently, we focus our attention on a specialised biomedical industrial district characterised by a strong pattern of innovative activity. We observe that R&D and networking/social capital arise as complementary driving forces of innovation outputs. When the empirical evidence confirms that this complementarity plays a key role, policy efforts should be targeted toward both market and non-market characteristics, rather than solely to the production of local public goods or innovation inputs as independent elements of firm performance. This is very important in terms of policy effectiveness. In fact, we argue that SC/networking dynamics might positively evolve only if the private opportunity cost of investing in R&D innovation is sufficiently low. Nevertheless, this exogenous economic incentive works as long as complementarity, as defined here, holds.     

Union Activism,Workers’ Satisfaction and Organizational Change

Abstract. This paper investigates the reaction of active union members towards workplace organizational changes. We use micro‐data from a large firm and estimate an empirical model which deals explicitly with the potential endogeneity of the union activist status. The data indicate that workers who become union activists are more likely to complain than members. Moreover, after proper allowance is made for the endogeneity of union activism, we find this effect to be reinforced. This result suggests that activists are not inherently against organizational changes, as compared to non‐activists, though they report higher dissatisfaction in anticipation of the greater loss in union rents that is likely to be associated with the change.     

The social regulation of corporate social irresponsibility: Reviewing the contribution of corporate reputation

Whilst it is assumed that stakeholders penalize and deter corporate social irresponsibility (CSI), instances of CSI persist. Correspondingly, the literature on social regulation—which describes how non-governmental stakeholders exert their regulatory influence on organizations—remains fragmented. To act as a springboard for future studies, this review examines the contribution of corporate reputation to our understanding of how CSI is socially regulated. Our analysis of a large (n = 448 studies) multidisciplinary body of literature unearths a set of nuanced relationships between CSI and corporate reputation. We synthesize a conceptual framework in order to map the diverse landscape of literature and its contributions. We then highlight important gaps among—as well as between—research streams to present a future research agenda. Accordingly, this review contributes to closing ‘the loop’ between CSI, corporate reputation and social regulation, thereby opening up new pathways for future research.     

External audit and goodwill write-off

Building on agency theory, we investigate whether and how salient external auditor characteristics (size, audit fees, non-audit fees, tenure) impact on the reported goodwill write-off. We use a sample of US firms applying SFAS 142. We find that Big-4 auditors are more prone to limit underestimated write-offs rather than overestimated write-offs and that auditors require higher fees from companies underestimating the write-offs. The findings are consistent with the auditors’ preference for more conservative goodwill and earnings values, which reduce their litigation and reputation costs. This preference can converge with the managerial interest to use unnecessary overestimated goodwill write-offs for earnings management purposes (e.g. to smooth the income or take big baths). Our findings do not support the hypotheses that non-audit fees and tenure affect the goodwill write-off. Our paper contributes to prior literature on external audit and financial accounting choices. Our study suggests that leniently audited discretional fair value estimates are likely to compromise the role of auditing (and of financial reporting) as an external control mechanism. Our study can contribute to the current policy debate around goodwill accounting.     

Investigating the association between callous‐unemotional traits with relational bullying and victimization: A cross‐national study

Prior research supports an association between callous‐unemotional (CU) traits with relational bullying, but evidence associating CU traits with relational victimization is limited. Further, the relationship between CU traits with relational “bully,” “bully‐victim,” and “victim” classifications has been largely neglected. The current study addresses these critical gaps in the literature using a cross‐national study design. The sample comprised of 1887 (51.5% of girls) Greek and Cypriot children (MAge = 11.17) who completed a battery of self‐report measures. Group differences suggested that children in the relational bully and bully‐victim groups scored higher on CU traits compared to children in the victim and low‐risk groups. Although these associations were similar across countries, boys in Greece were more likely to be identified in the bullying only group. In contrast, boys in Cyprus represented the higher percentage identified as bully‐victims and girls in Cyprus represented the higher percentage identified as victim‐only. Regression analysis results indicated that CU traits predicted relational bullying but not victimization. Notwithstanding, other important unexamined factors known to contribute to relational bullying and victimization, our findings suggest that prevention efforts should consider CU traits in order to protect youth from relational bullying. However, differences between countries and gender should also be taken into account.
