Propensity score weighting is a tool for causal inference to adjust for measured confounders in observational studies. In practice, data often present complex structures, such as clustering, which make propensity score modeling and estimation challenging. In addition, for clustered data, there may be unmeasured cluster-level covariates that are related to both the treatment assignment and outcome. When such unmeasured cluster-specific confounders exist and are omitted in the propensity score model, the subsequent propensity (...) class='Hi'>score adjustment may be biased. In this article, we propose a calibration technique for propensity score estimation under the latent ignorable treatment assignment mechanism, i. e., the treatment-outcome relationship is unconfounded given the observed covariates and the latent cluster-specific confounders. We impose novel balance constraints which imply exact balance of the observed confounders and the unobserved cluster-level confounders between the treatment groups. We show that the proposed calibrated propensity score weighting estimator is doubly robust in that it is consistent for the average treatment effect if either the propensity score model is correctly specified or the outcome follows a linear mixed effects model. Moreover, the proposed weighting method can be combined with sampling weights for an integrated solution to handle confounding and sampling designs for causal inference with clustered survey data. In simulation studies, we show that the proposed estimator is superior to other competitors. We estimate the effect of School Body Mass Index Screening on prevalence of overweight and obesity for elementary schools in Pennsylvania. (shrink)

:In this article, we carefully examine two important implementation issues when estimating propensity scores using generalized boosted models, a promising machine learning technique. First, we examine which of the following methods for tuning GBM lead to better covariate balance and inferences about causal effects: pursuing covariate balance between the treatment groups or tuning the propensity score model on the basis of a model fit criterion. Second, we examine how well GBM can handle irrelevant covariates that are included (...) in the estimation model. We find that chasing balance rather than model fit when estimating propensity scores yielded better covariate balance and more accurate treatment effect estimates. Additionally, we find that adding irrelevant covariates to GBM increased imbalance and bias in the treatment effects. The findings from this paper have useful implications for other work focused on improving methods for estimating propensity scores. (shrink)

Corrupt regulatory environment encourages firms to deploy middlemen for speedy and assured acquisition of different services from regulatory agencies. Using a World Bank dataset of 2210 Indian manufacturing firms, this article examines how firms with middlemen deal with corrupt governmental agencies for its operational efficiency. Our results demonstrate that deployment of middlemen by the firms is often accompanied by a substantial increase in operational delay, relatively trigger more consumption of senior management’s time on regulatory disentanglement, enhance the likelihood/tendency to pay (...) bribe, and likely to face more court cases as a means of restitution of legal rights. As firm-specific attributes may contaminate our preliminary results, we utilized the propensity score framework to examine relationships among variables of interests. Our study contributes to the inconspicuous part of the corruption literature by attempting to present a comprehensive but indirect assessment of the functions of middlemen that predominantly remained unattended except some scattered descriptive, case-based anecdotal presentations.

Continuum of care throughout pregnancy, delivery and post-delivery has proved to be a critical health intervention for improving the health of mothers and their newborn children. Using data from the fourth wave of the National Family Health Survey conducted in 2015–16, this study examined the correlates of utilization of maternal health care services and child immunization following the continuum of care approach in India. The study also assessed whether the continuity in utilizing maternal health care services affects the immunization of (...) children. A total of 33,422 survey women aged 15–49 were included in the analysis of maternal health care indicators, and 8246 children aged 12–23 months for the analysis of child immunization. The results indicated that about 19% of the women had completed the maternal health continuum, i.e. received full antenatal care, had an institutional delivery and received postnatal care. Women with a higher level of education and of higher economic status were more likely to have complete continuum of care. Continuity of maternal health care was found to be associated with an increase in the immunization level of children. It was observed that 76% of the children whose mothers had complete continuum of care were fully immunized. Furthermore, the results from propensity score matching revealed that if mothers received continuum of care, the chance of their child being fully immunized increased by 17 percentage points. The results suggest that promotion of the continuum of maternal health care approach could help reduce not only the burden of maternal deaths in India, but also that of child deaths by increasing the immunization level of children.

This study examines the relationship between cognitive moral development (CMD), productivity features of information technology (IT) and unethical behavior or misconduct. Using an experimental design that randomly assigns subjects to one of four unique technology conditions, we assess the relationship between a subjects' predominant level of CMD and ethical misconduct on IT-oriented work tasks. Our results show that both higher levels of CMD and increased levels of IT productivity features at one's disposal have a significant role to play in explaining (...) observed behavior in our sample. We find that CMD as measured by the Defining Issues Test's P-score is negatively related to task misconduct. Conversely, IT productivity features such as copy-and-paste are positively related to task misconduct. In addition, the CMD—misconduct relationship is significantly diminished by the introduction of IT productivity features. Lastly, a series of hazard analyses are conducted to explore the boundaries of our principal findings. These results demonstrate the significant role of technology in enabling negative behavior and the relative inability of subjects' use of principled moral reasoning to overcome it. Implications of these findings for academics and business managers are offered, as well as recommendations for mitigating misconduct in both academic and workplace environments. (shrink)

Corporate social performance (CSP) has become a widely applied concept, discussed in most large firms’ corporate reports and the academic literature alike. Unfortunately, CSP has largely been employed as a way of demonstrating corporate social responsibility (CSR) in practice, or to justify the business case for CSR in academia by relating some measure of CSP to some measure of financial performance. In this article, we discuss multiple shortcomings to these approaches. We argue that (1) CSR activities need to be managed (...) and measured as projects and aggregated to the business or corporate level using a project portfolio; (2) appropriate measures need to be identified that move away from reporting the firm’s activities toward quantifying actual social outcomes achieved; and (3) given the types of projects prevalent in CSR, statistical evaluation methods common in other fields (ideally, pre-test post-test control group designs, such as used in medicine or propensity score matching for ongoing or past projects) should be employed to properly measure outcomes. We make a first, albeit imperfect, attempt at using such an approach with data collected on behalf of the Patrimonio Hoy project, a well-publicized CSR initiative carried out by Cemex in Mexico. We show that the results from this data reinforce concerns voiced earlier in this article. (shrink)

This study investigates the relation between CEO compensation and corporate fraud in China. We document a significantly negative correlation between CEO compensation and corporate fraud using data on publicly traded firms between 2005 and 2010. Our findings are consistent with the hypothesis that firms penalize CEOs for fraud by lowering their pay. We also find that CEO compensation is lower in firms that commit more severe frauds. Panel data fixed effects and propensity score methods are used to demonstrate (...) these effects. Our results also indicate that corporate governance mechanisms influence the magnitude of punishment. We find that CEOs of privately controlled firms, firms that split the posts of CEO and chairman, and CEOs of firms located in developed regions suffer larger compensation penalties for committing financial fraud. Finally, we show that CEOs at firms that commit fraud are more likely to be replaced compared to those at non-fraud firms. (shrink)

We draw from upper echelons theory to investigate whether the presence of a chief sustainability officer is associated with better corporate environmental performance in highly polluting industries. Such firms are under strong pressure to remediate environmental damage, to comply with regulations, and to even exceed environmental standards. CSOs in these firms are likely to be hired as legitimate agents to lead and successfully implement environmental strategy aimed at reducing pollution levels. Interestingly and contrary to our expectations, we found that the (...) presence of a CSO is associated with higher levels of pollution emissions. Nonetheless, we found that the CSO has a positive influence on a firm’s environmental performance if faced with strict environmental regulations. We argue that the enforcement of environmental regulations enhances monitoring and accountability of pollution emissions. The sample for this study comprised all the S&P 500 firms required by the Environmental Protection Agency to annually report their toxic emissions to the Toxic Release Inventory. Data were collected for a 6-year period from 2006 to 2011. We used a panel data regression and employed propensity score matching to correct for potential endogeneity problems. (shrink)

The question of whether females tend to act more ethically or risk-averse compared to males is an interesting ethical puzzle. Using a large sample of US firms over the 1992–2014 period, we investigate the effect that the gender of a chief executive officer has on earnings management using classification shifting. We find that the pre-Sarbanes–Oxley Act period was characterized by high levels of classification shifting by both female and male CEOs, but the magnitude of such practices is, surprisingly, significantly higher (...) in firms with female CEOs than in those with male CEOs. By contrast, our results suggest that following the passage of the punitive SOX Act, classification shifting by female CEOs declined significantly, whilst it remained pervasive in firms with male CEOs. This suggests that the observable differences in financial reporting behavior between male and female CEOs seem to be because female CEOs are more risk-averse, but not necessarily more ethically sensitive than their male counterparts are. The central tenets of our findings remain unchanged after several additional checks, including controlling for alternative earnings management techniques, corporate governance mechanisms, CEO and chief financial officer characteristics and propensity score-matching.

We evaluate the relationship between the appointment of women to CEO or Chair positions and firm performance, and shed light on the differences between family and nonfamily firms. By using a propensity score matching approach on a sample of 394 French firms over the period 2001–2010, we find major discordances between women’s leadership style and family business expectations relative to firm performance, as measured by return on assets and Tobin’s q. Notably, our results support the conjecture that family (...) firms, which are more conducive to transformational leadership, offer women a more appropriate climate for exercising the function of Chair than that of CEO. In contrast, women CEOs perform better in nonfamily firms. Our findings move away from the predominant focus on barriers and stereotypes images about the female leadership and support the contingency theory of leadership, which states that the effectiveness of a leadership style depends on the organization and culture in which leaders operate, and on task-related positions.

In this article, we propose that giving in cash and non-cash differ in their relation with the giving firm’s future corporate financial performance and only cash giving is associated with future CFP. Using a novel dataset from ASSET4 that differentiates corporate giving over a sample period of 2002–2012, we examine three competing hypotheses: agency cost hypothesis that cash giving reflects agency cost and destroys value for shareholders, investment hypothesis that cash giving is an investment by management that aims for better (...) future return, and information hypothesis that cash giving has informational value to shareholders as cash is a critical resource at a firm and giving is a decision by managers who are insiders. We find that indeed, only cash giving is positively associated with future CFP and firm value, measured by Fama–French five-factor abnormal risk-adjusted stock returns, future return on assets, and Tobin’s Q. In addition, we find that the positive association exists only between excess, i.e., unexpected, but not expected cash giving and future CFP. Our empirical findings support the information hypothesis, but neither the agency hypothesis nor the investment hypothesis, and are robust to a number of endogeneity tests, including orthogonalized cash giving, instrumental variable regression using geography-based instruments, and propensity score matching. Furthermore, we show that the positive association between future CFP and unexpected cash giving is only pronounced at firms with good governance and relatively higher sales growth where agency problems are less likely, and at firms with no alternative mechanisms to demonstrate the strength of cash flow. Additionally, we do not find evidence that suggests in-kind giving to possess any informational value. (shrink)

Does environmental management help foreign firms outperform local firms in emerging economies? While existing research suggests that environmental management may or may not benefit firm performance, the question is particularly under-investigated in the emerging economy context. Using the data on foreign investment into China, this study explores whether foreign firms that are under greater environmental pressure, at home or at the host, outperform comparable local firms in an emerging host country. In making this comparison, we use propensity-score matching (...) and a difference-in-differences approach to handle the problem of endogeneity inherent in comparing the performances of foreign versus local firms. We find empirical support that foreign firms perform better than local firms when they are under high environmental pressure in the emerging host country, and this result is driven by the foreign firms originating from countries with high environmental pressure.

This study examines the influence of auditor-CEO surname sharing on financial misstatement and further investigates whether the above effect depends on hometown relationship and the rarity of surnames, respectively. Using hand-collected data from China, the findings show that ACSS is significantly positively related to financial misstatement, suggesting that the auditor-CEO ancestry membership elicits the collusion and increases the likelihood of financial misstatement. Moreover, ACSS based upon hometown relationship leads to significantly higher likelihood of financial misstatement, compared with ACSS without hometown (...) relationship. Furthermore, the positive relation between ACSS and financial misstatement is more pronounced for rare surnames than for common surnames. The above findings are robust to sensitivity tests on the basis of different measures of ACSS and financial misstatement, and my conclusions are still valid after using the propensity score matching approach to address the endogeneity concerns.

This study investigates how managers in firms that have committed fraud strategically use socially responsible activities in coordination with their fraudulent financial reporting practices. Using propensity score matching to select control firms that have a similar probability of fraud in the pre-fraud benchmark period, we find that the corporate social responsibility performance of fraudulent firms in the fraud-committing period is significantly higher compared with the CSR performance of non-fraudulent control firms during this period, and compared with that during (...) their own pre-fraud benchmark periods. This higher CSR performance by fraudulent firms is achieved by means of investing in both stakeholder and third-party CSR categories and by improving in CSR strengths. Furthermore, the increase in CSR performance is more pronounced for fraudulent firms with a weak governance environment, and for firms located in high-religiosity states. Overall, our findings suggest that fraudulent firms strategically adjust their CSR performance to coordinate with their fraudulent financial activities. (shrink)

The role of competitive funds as a source of funding for academic research has increased in many countries. For the individual researcher, the receipt of a grant can influence both scientific production and career paths. This paper focuses on the importance of the receipt of a research grant for researchers’ academic career paths utilizing a mixed methods approach that combines econometric analysis with in-depth qualitative interviews. The analysis has novel elements both in terms of its subject (impact of funding grants (...) on individuals’ academic career paths) and approach. The results of this study indicate that while research grants have a positive impact on the research performed under the grant itself, there are very important secondary effects on research performance through positive effects on academic career advancement. The probability of obtaining a full professorship for grant recipients is almost double that for rejected applicants, 16 percent compared to 9 percent. The probability for career advancement in general is about 9 percentage points higher for grant recipients. Qualitative interviews support these quantitative results by providing insights into how grants impact research careers, through heightened status, recognition, networking and other factors.

This paper examines whether firms strategically legitimize large labor dismissals by performing ex-ante downward earnings management. We further assess whether the effect is larger under stakeholder pressure and whether these practices influence the external perception of firms’ behavior. As laying off employees without an economic reason is perceived as a breach of the social contract, stakeholders pressure firms to provide economic justification for LLDs. We argue that firms strategically legitimize LLDs by artificially worsening their financial performance through downward earnings management. (...) From a sample of European listed firms for the period 1998–2014, using a propensity score matching model to control for differences in observable characteristics between LLD and non-LLD firms, we find that firms manage their earnings downward in the year prior to LLDs. These results are more pronounced in the presence of high stakeholder pressure. As such, firms with stronger trade unions, higher visibility, stricter employment protection legislation, and more stakeholder-oriented legal environments have stronger incentives to manage earnings downward before LLDs. Finally, we document that downward earnings management prior to LLDs is effective at legitimizing LLDs, offsetting the negative external perceptions of firms in the aftermath of LLDs. This study contributes to the business ethics literature by identifying unintended consequences of stakeholder pressure around LLDs. It also brings important empirical insights into how ethically questionable decisions are strategically legitimized through further unethical practices. (shrink)

We investigate the effect of Lesbian, Gay, Bisexual, and Transgender -supportive corporate policies on credit ratings. To the extent that LGBT-friendly policies are beneficial to the firm and therefore improve its expected cash flows, credit rating agencies should assign more favorable credit ratings to the firm. To alleviate endogeneity concerns, we exploit the variations in the LGBT populations across the states in the U.S. as our instrument. Our instrumental-variable analysis reveals that firms that adopt LGBT-supportive corporate policies enjoy better credit (...) ratings, supporting the stakeholder and good management hypothesis. Further analysis using propensity score matching also yields consistent results. (shrink)

Using a dataset of corporate philanthropic gifts of $1 million or more, we examine the influence of corporate donors on the performance of recipient non-profit organizations. We find that corporate donors positively influence NPO performance, specifically in the form of higher revenues per employee, program ratios, and fundraising returns. We find little evidence that large foundation or individual donors similarly enhance organizational performance. In additional analysis, we find that large corporate donations matter when the corporation is more likely to have (...) influence over the recipient NPO. These findings suggest that corporate donors provide the monitoring and expertise needed to enhance organizational performance beyond simply providing funding to NPOs. Our results are robust to a two-stage model and propensity score matching to address endogeneity concerns. While prior research has examined the effect of corporate philanthropy on donor organization performance, we contribute to the literature by examining whether corporate philanthropy also improves recipient organization performance.

While a growing body of literature has examined the link between green activities and firm innovation, little attention has been paid to the underlying mechanisms through which green activities take effect. This paper leverages the context of ISO 14001 certification among Chinese listed firms to investigate how the certification of environmental management system to ISO 14001 shapes corporate technological innovation. Drawing from the resource-based view and the resource management perspective, we argue that EMS certification to ISO 14001 facilitates corporate technological (...) innovation through the mediating effects of firms’ internal resource management practices, namely resource utilization, resource accumulation, and resource allocation. A difference-in-differences research design, together with the propensity score matching approach and the instrumental variable technique, provides corroborating evidence for our predictions. The current research not only makes substantial contributions to the literature, but also provides important ethical implications for both policymakers and firm managers. (shrink)

In this paper we present a continuous extension for longitudinal analysis settings of the recently proposed Covariate Balancing Propensity Score methodology. While extensions of the CBPS methodology to both marginal structural models and general treatment regimes have been proposed, these extensions have been kept separately. We propose to bring them together using the generalized method of moments to estimate inverse probability weights such that after weighting the association between time-varying covariates and the treatment is minimized. A simulation analysis (...) confirms the correlation-breaking performance of the proposed technique. As an empirical application we look at the impact the gradual roll-out of Seguro Popular, a universal health insurance program, has had on the resources available for the provision of healthcare services in Mexico.

This study assessed whether and how government–business partnerships offer a unique platform that targets profound environmental impacts via the promotion of radical eco-innovation. It applied transactional cost and complementary logics to explain the rationale of GBP formation for radical eco-innovation, and further assessed the operation of GBPs from governance, learning, and rulemaking aspects. This study applied propensity score matching technique to empirically test these theoretical associations using 225 observations representing 166 U.S. firms’ participation in 192 environmental alliances between (...) 1985 and 2013. The study results confirmed GBPs’ role in channeling public and private efforts in pursuing transformative environmental change via the adoption of radical eco-innovation goals. Results highlight four critical elements of GBP operation—effective governance, exploration learning, cognitive learning, and rulemaking—that enable participants to embrace these radical environmental solutions.

Firms have traditionally responded to environmental violations by increasing information disclosure and/or communication to manage stakeholder perceptions. As such, these approaches may be symbolic in nature, with no genuine intention to improve the environment. We draw from restorative justice grounded in stakeholder theory and explore a relatively new approach in the form of supplemental environmental projects aimed at restoring the environment, and empirically examine the role of corporate governance in firms’ decisions to undertake reparative actions. Using environmental violations and SEPs (...) data from the US Environmental Protection Agency between 2002 and 2015, we find that firms with smaller boards are more likely to undertake SEPs. We also find that firms with higher board independence and CEO duality undertake SEPs more frequently; however, board gender diversity and the existence of a sustainability committee appear to have no impacts. These results are robust to propensity score matching and an alternative data source. We extend the scope of stakeholder theory by emphasizing a new approach—restorative justice—by which corporations can repair damaged relationships and also improve the environment. We also contribute to corporate governance and environmentalism literature by identifying governance structures that promote environmental restorative justice. Thus, our study will inform different stakeholders, including regulators, shareholders, and boards of directors, and will open new avenues for business ethics scholarship. (shrink)

OBJECTIVE: Following two randomized controlled trials that demonstrated reduced mortality and better neurological outcome in cardiac arrest patients, mild therapeutic hypothermia was implemented in many intensive care units. Up to now, no large observational studies have confirmed the beneficial effects of mild therapeutic hypothermia. DESIGN: Internet-based survey combined with a retrospective, observational study. PATIENTS: All patients admitted to an intensive care unit in The Netherlands after cardiac arrest from January 1, 1999 until January 1, 2009. DATA SOURCE: Dutch National Intensive (...) Care Evaluation database. METHODS: The moment of implementation of mild therapeutic hypothermia for each hospital participating in the Dutch National Intensive Care Evaluation database was determined with an Internet survey. To compare mortality before and after implementation of mild therapeutic hypothermia, the odds ratio adjusted for Simplified Acute Physiology Score II score, age, gender, propensity score, and in- or out-of-hospital cardiac arrest was calculated. Patients were excluded if 1) they were admitted to an intensive care unit that did not respond to the survey, 2) they were admitted within 3 months after implementation of mild therapeutic hypothermia, 3) they had a Glasgow Coma Scale score of >8, or 4) they did not satisfy the Simplified Acute Physiology Score II inclusion criteria. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: A total of 13,962 patients were admitted to an intensive care unit following cardiac arrest. In total 8,645 patients were excluded, 5,544 because of a Glasgow Coma Scale score of >8. Of the resultant 5,317 patients, 1,547 patients were treated before and 3,770 patients after implementation of mild therapeutic hypothermia. Patients admitted after implementation of mild therapeutic hypothermia had lower minimal and maximal temperatures (p < .0001) during the first 24 hrs on the intensive care unit compared to patients admitted before implementation of mild therapeutic hypothermia. The adjusted odds ratio of the hospital mortality of patients treated after implementation of mild therapeutic hypothermia was 0.80 (95% confidence interval of 0.65-0.98, p = .029). CONCLUSION: The results of this retrospective, observational survey suggest that implementation of mild therapeutic hypothermia in Dutch intensive care units is associated with a 20% relative reduction of hospital mortality in cardiac arrest patients.

This paper examines the relationship between loan guarantees and audit fees as well as the moderating effect of corporate social responsibility. We find that guaranteeing another entity’s debt significantly increases firms’ own audit fees. However, the disclosure of CSR information attenuates the fee-increasing effects of loan guarantees. A closer examination reveals that the role of CSR is attributable to the information effect rather than the signal effect. Our results are robust to the use of a quasi-natural experiment, a propensity (...) score matching analysis, a Heckman two-stage treatment effect model and alternative proxies. This work makes new contributions to the current understanding of the consequences of loan guarantees, determinants of audit fees and value of CSR disclosure. (shrink)

In their recent book, Is Inequality Bad for Our Health?, Daniels, Kennedy, and Kawachi claim that to “act justly in health policy, we must have knowledge about the causal pathways through which socioeconomic (and other) inequalities work to produce differential health outcomes.” One of the central problems with this approach is its dependency on “knowledge about the causal pathways.” A widely held belief is that the randomized clinical trial (RCT) is, and ought to be the “gold standard” of evaluating the (...) causal efficacy of interventions. However, often the only data available are non-experimental, observational data. For such data, the necessary randomization is missing. Because the randomization is missing, it seems to follow that it is not possible to make epistemically warranted claims about the causal pathways. Although we are not sanguine about the difficulty in using observational data to make warranted causal claims, we are not as pessimistic as those who believe that the only warranted causal claims are claims based on data from (idealized) RCTs. We argue that careful, thoughtful study design, informed by expert knowledge, that incorporates propensity score matching methods in conjunction with instrumental variable analyses, provides the possibility of warranted causal claims using observational data.

Personality signatures are sets of if-then rules describing how a given person would feel or act in a specific situation. These rules can be used as the major premise of a deductive argument, but they are mostly processed for social cognition purposes; and this common usage is likely to leak into the way they are processed in a deductive reasoning context. It is hypothesised that agreement with a Modus Ponens argument featuring a personality signature as its major premise is affected (...) by the reasoner's own propensity to display this personality signature. To test this prediction, Modus Ponens arguments were constructed from conditionally phrased items extracted from available personality scales. This allowed recording of (a) agreement with the conclusion of these arguments, and (b) the reasoner's propensity to display the personality signature, using as a proxy this reasoner's score on the personality scale without the items used in the argument. Three experiments ( N = 256, N = 318, N = 298) applied this procedure to Fairness, Responsive Joy, and Self-Control. These experiments yielded very comparable effects, establishing that a reasoner's propensity to display a given personality signature determines this reasoner's agreement with the conclusion of a Modus Ponens argument featuring the personality signature.

There is a debate over whether actions that resist devaluation are primarily habit- or goal-directed. The incentive habit account of compulsive actions has received support from behavioral paradigms and brain imaging. In addition, the self-reported Creature of Habit Scale has been proposed to capture inter-individual differences in habitual tendencies. It is subdivided into two dimensions: routine and automaticity. We first considered a French version of this questionnaire for validation, based on a sample of 386 undergraduates. The relationship between two dimensions (...) of habit and the risk of substance use disorder and impulsive personality traits was also investigated. COHS has good psychometric properties with both features of habits positively associated with an Obsessive-Compulsive Inventory score. Besides, the propensity to rely more on routines was associated with lower levels of alcohol abuse and nicotine use, suggesting that some degree of routine might act as a protective factor against substance use. In contrast, a high automaticity score was associated with an increased risk of harmful alcohol use. These results demonstrate that the COHS is a valid measure of habitual tendencies and represents a useful tool for capturing inter-individual variations in drug use problems in undergraduates.

The concept of "fitness" is a notion of central importance to evolutionary theory. Yet the interpretation of this concept and its role in explanations of evolutionary phenomena have remained obscure. We provide a propensity interpretation of fitness, which we argue captures the intended reference of this term as it is used by evolutionary theorists. Using the propensity interpretation of fitness, we provide a Hempelian reconstruction of explanations of evolutionary phenomena, and we show why charges of circularity which have (...) been levelled against explanations in evolutionary theory are mistaken. Finally, we provide a definition of natural selection which follows from the propensity interpretation of fitness, and which handles all the types of selection discussed by biologists, thus improving on extant definitions.

The paper provides a new critical perspective on the propensity interpretation of fitness, by investigating its relationship to the propensity interpretation of probability. Two main conclusions are drawn. First, the claim that fitness is a propensity cannot be understood properly: fitness is not a propensity in the sense prescribed by the propensity interpretation of probability. Second, this interpretation of probability is inessential for explanations proposed by the PIF in evolutionary biology. Consequently, interpreting the probabilistic dimension (...) of fitness in terms of propensities is neither a strong motivation in favor of this interpretation, nor a possible target for substantial criticism.

Quantum mechanics and probability theory share one peculiarity. Both have well established mathematical formalisms, yet both are subject to controversy about the meaning and interpretation of their basic concepts. Since probability plays a fundamental role in QM, the conceptual problems of one theory can affect the other. We first classify the interpretations of probability into three major classes: inferential probability, ensemble probability, and propensity. Class is the basis of inductive logic; deals with the frequencies of events in repeatable experiments; (...) describes a form of causality that is weaker than determinism. An important, but neglected, paper by P. Humphreys demonstrated that propensity must differ mathematically, as well as conceptually, from probability, but he did not develop a theory of propensity. Such a theory is developed in this paper. Propensity theory shares many, but not all, of the axioms of probability theory. As a consequence, propensity supports the Law of Large Numbers from probability theory, but does not support Bayes theorem. Although there are particular problems within QM to which any of the classes of probability may be applied, it is argued that the intrinsic quantum probabilities are most naturally interpreted as quantum propensities. This does not alter the familiar statistical interpretation of QM. But the interpretation of quantum states as representing knowledge is untenable. Examples show that a density matrix fails to represent knowledge. (shrink)
