Sin sectors and negative screening

In this research, I analyse how exposure to sin sectors impacts the financial performance of socially responsible (SR) funds. I also analyse the question of whether or not these funds keep their word and are less exposed to the controversial sectors that they claim to exclude in their prospectuses. Additionally, I analyse how local political and religious factors exert an influence on the exposure of SR funds to sin sectors. Consequently, I analyse a sample comprising 136 SR mutual funds that were domiciled in the U.S. market in the period March 2017–April 2020 and who invest in domestic and global equity, of which 92 implement negative screens on at least 1 of 12 controversial activities. My results show that for seven (three) of the controversial sectors that were analysed, the exposure of SR funds to these sectors jeopardises (improves) their financial performance. Furthermore, SR mutual funds who perform negative screens tend to live up to their name and are less exposed to the sector/s that they claim to exclude. In addition, SR mutual funds managed by companies located in Democrat-leaning states are less exposed to sin sectors, and that the effect of local religiosity depends on the specific sector analysed.     

Behaviour‐Based and Outcome‐Based Control Systems: A Meta‐Analytic Study

Sales control systems are instruments used by firms to improve performance and other organizational outcomes. To understand their antecedents and consequences, this paper conducts a meta‐analysis based on 104 studies. The results showed significant relationships between behaviour‐ and outcome‐based control systems and the complexity of the products, bonuses, financial performance, sales innovation, organizational support and satisfaction with supervisors. The outcomes revealed that behaviour‐based control systems were the most effective mechanism in turbulent markets and for determining financial performance. However, outcome‐based control systems were the most efficient instrument for complex products.     

Will elders provide for their grandchildren? Unconditional cash transfers and educational expenditures in Bolivia

We take advantage of repeated cross‐sectional household surveys and a sharp discontinuity created by the introduction of an unconditional cash transfer to elders in Bolivia, to evaluate its impact on educational expenditures on children within a household. We find positive and significant impacts of the program at the aggregate level. We also find that the program has stronger effects on indigenous populations as well as on female and rural populations. Our results are robust to a series of falsification tests, survey structure, model specification, and estimation methods.     

On the relationship between sectorial and institutional structural changes

Successful development processes involve not only ‘sectorial structural change’, shifts of factors between different productive sectors, but also, ‘institutional structural change’, shifts of factors from unproductive activities (predation) to productive ones. This paper analyzes the feedback process between the sectorial and the institutional structural changes in a model in which the labor share in agriculture is lower than in other sectors. Along the transition sectorial structural change emerges: employment in agriculture declines. Consequently, total labor share increases, raising the reward for working (while discouraging predation) and so, fostering institutional structural change. This, in turn, encourages capital accumulation, promoting sectorial structural change. This feedback mechanism widens differences in productivity and institutions among countries. Whereas zero-cost policies aimed to build institutions have positive effects, costly policies have uncertain effects due to complex feedback mechanisms.     

Short-Run and Long-Run Effects of Copper Mining on Peru’s Recent Economic Growth

Peru is the second-largest producer and exporter of copper in the world. This paper proposes a novel approach to assess short-run and long-run effects of copper on Peru’s recent economic growth. Annual data over the 2014–2018 period were used to calculate a Mining Contribution Index (MCI). An institutional quality indicator of the World Competitiveness Index of the World Economic Forum measured the dependence of Peruvian economic growth on mining and the quality of its institutions, respectively. Then, monthly data during the period 2005–2018 were used to run vector autoregressive (VAR) and vector error correction (VEC) models to measure copper’s effects on the country’s economy over time. VAR-VEC models included copper production, exports, international price, investment, taxes paid by producing companies, and Peru’s gross domestic product (GDP). Stationarity and causality of variables were verified with the Augmented Dickey-Fuller and Granger tests, respectively. Due to the presence of non-stationary variables, a VEC model was implemented to forecast short- and long-run effects. The main results show that real GDP responds to copper output and other related explanatory variables differently, depending upon the instrument applied. Peruvian GDP has increased dependence on copper mining. The quality of its institutions could explain the presence of Dutch Disease or resource curse theory. Short- and long-run effects of copper output on GDP were generally statistically non-significant. GDP was statistically significant in relation to other mining variables, such as copper exports and the international price of copper.

     

Performance Measures in Dose-Finding Experiments

In the first phase of pharmaceutical development, and assuming that the probability of positive response increases with dose, the main statistical goal is to estimate a percentile of the dose–response function for a given target value $\mathrm{\Gamma }$. We compare the Maximum Likelihood and centred isotonic regression estimators of the target dose and we discuss several performance criteria to assess inferential precision, the amount of toxicity exposure and the trade-off between them for a set of some exemplary adaptive designs. We compare these designs using graphical tools. Several scenarios are considered using simulation, including the use of several start-up rules, the change of slope of the dose-toxicity function at the target dose and also different theoretical models, as logistic, normal or skew-normal distribution functions.     

Using reputation for corporate sustainability to tackle banks digitalization challenges

The new landscape in the financial sector, characterized by fierce competition and the entrance of new technological players, has forced banks to speed up their digital transformation. However, for banks, digitalization entails challenges that can hinder the potential benefits and compromise their survival. In this context, we argue that the reputation generated by corporate sustainability (RCS) may offset these digitalization drawbacks. In particular, we find that the combination of RCS and digitalization facilitates in transforming the organizational nature of banks by simultaneously narrowing their boundaries and expanding their scope. We empirically confirm our hypotheses by analyzing a panel of 110 multinational banks from developed countries.     

Organizational culture in a terminally ill hospital

This study analyzed an organizational culture in a community hospital in Texas to measure organizational culture change and its impact on Patient Satisfaction (PS). The study employed primary and secondary data, combining quantitative and qualitative methods for a case study. Participant observation was used and archival data were collected to provide a better understanding of the organizational culture and the context in which change was taking place. This study also applied a "Shared Vision" of the organization as the central process in bringing forth the knowledge shared by members of the community hospital who were both subjects and research participants. The results from the study suggest an increase in PS due to the shared vision of one subculture within the hospital. There were powerful subcultures in this organization based on occupation and specialization, and their interests and functional orientations were not conducive to a systems approach. Hospital management was conducted in "silos" and there was lack of feedback between organizational levels of the hospital, especially in financial management, with organizational dysfunctionality in reacting and adapting to the health care market.     

Salesperson implementation of sales strategy and its impact on sales performance

ABSTRACT

It has been observed in the academic and practitioner literature, a disconnect between the activities of salespeople and the sales strategy espoused by sales organizations. This study examines organizational and individual factors that can influence salespersons’ willingness and ability to implement sales strategy. This paper also seeks to examine the performance implications of sales strategy implementation by salespeople. Data were collected from a sample of 190 business-to-business salespeople in different industries. The study’s hypotheses were tested using partial least squares (PLS). The results of the study show that the different types of sales force control (behavior control and outcome control) has contrasting effects on salesperson market and technical knowledge and salesperson implementation of sales strategy. The results also demonstrate that when salespeople implement sales strategy as part of their sales process, it has a positive effect on their sales performance.     

Gender disparities: a medical detoxification program

Significant gaps exist in health care regarding gender in the United States. Health status, social roles, culturally patterned behavior and access to health care can be influenced by gender. Women have been the primary users of health care and minority women usually have received poorer quality care than Non-Hispanic White (NHW) females. The objectives of this study were to identify gender, racial and ethnic disparities in access to substance abuse treatment in a Texas hospital. Secondary data collected on 1,309 subjects who underwent detoxification were studied. Gender, race/ethnicity, drug of abuse, relapse and financial classification were included in the analysis. Results indicate Hispanic females and Non-Hispanic Black (NHB) females were about 5 and 3.5 more likely than NHW females to use Medicaid services respectively (p < .05). NHW and NHB males were more likely to use Medicare than females (p < .05). NHB and Hispanic females were 5.8 and 2.1 times more likely to receive care for abuse of cocaine when compared to NHW females respectively (p < .05). Hispanic females were 2.3 times more likely to relapse than Non-Hispanic females, and uninsured NHB females were 7.1 times at a higher risk to abuse multiple drugs compare to NHW females (p < .05). Socio-economic factors, lower labor force participation rates, and less financial independence can explain females utilizing more often Medicaid regardless of their race/ethnicity. These results can be also explained by aggressive case management utilization, socio cultural barriers and/or discriminatory practices, both intentional and unintentional.
