Inflation,output and stock prices: evidence from Latin America

Research in economics and finance documents a puzzling negative relationship between stock returns and inflation rate in markets of industrialized economies. The present study investigates this relationship for the developing markets of Peru and Chile. Fama's model of linkages between inflation and real economic activity constitutes the theoretical framework of this paper. The study tests whether the negative relationship between equity returns and inflation is a result of a ‘proxy effect’, namely, a negative relationship between inflation and real economic activity. The evidence for Peru and Chile does not provide strong support for Fama's hypothesis. It is shown that the negative relationship between the real stock returns and unexpected inflation persists after purging inflation of the effects of the real economic activity. The long‐run equilibrium between stock prices and general price levels is weak, as indicated by the findings of the Johansen and Juselius co‐integration tests. However, in both economies, stock prices and general price levels seem to show a strong long‐run equilibrium with the real economic activity. These findings suggest that in the long‐run, Fama's propositions A and B are supported for Peru and Chile. The disparity between traditional regression and co‐integration test results suggest that it may be prudent to re‐examine the proxy effect in the framework of a long‐run relationship before denying its validity.

Improvements in the safety screening of resin manufacturing processes

Consequences of acrylic resin reactor runaways can be devastating, as it is evident in investigation reports of industrial accidents. Critical in preventing major accidents is the safety screening of any acrylic resin formula to be manufactured in large scale. Computer model simulations facilitate the evaluation of “layers of protection” against acrylic polymerization runaways. This work describes the adaptation of a chemical process dynamic simulator (DuPont™ TMODS™) for use in simulating acrylic polymerization runaways. “Loss of cooling” and “monomer pooling (accumulation)” scenarios are the causes of these runaways. Simulations show that scenarios leading to “monomer pooling” result in more energetic runaways and to larger emergency relief capacity requirements than “loss of cooling” scenarios. © 2009 American Institute of Chemical Engineers Process Saf Prog, 2009     

Successful Leadership in Global Public Good Provision: Incorporating Behavioural Approaches

In the standard model of voluntary public good provision and other game theoretic models, climate-friendly leadership of a country is not successful: A unilateral increase of this country’s greenhouse gas abatement measures, i.e., contributions to the global public good of climate protection, will not lead to a positive reaction by the other countries but instead trigger a reduction of their abatement efforts and thus a crowding-out effect. In this paper it is shown how this undesired consequence need no longer occur when elements of behavioral economics are incorporated in the otherwise standard model of public good provision. In particular, strategic complementarities between the public good contribution of the leading country and those of the follower may result either if the follower has specific non-egoistic or other-regarding preferences or if the leader’s contribution positively affects the follower’s beliefs, i.e., his conjectural variations, about the leader’s behaviour.     

Burden of illness for super-refractory status epilepticus patients

Objective: To provide an estimate of the annual number of super-refractory status epilepticus (SRSE) cases in the US and to evaluate utilization of hospital resources by these patients.

Methods: The Premier Hospital Database was utilized to estimate the number of SRSE cases based on hospital discharges during 2012. Discharges were classified as SRSE cases based on an algorithm using seizure-related International Classification of Diseases-9 (ICD-9) codes, Intensive Care Unit (ICU) length of stay (LOS), and treatment protocols (e.g. benzodiazepines, anti-epileptic drugs (AEDs), and ventilator use). Secondary analyses were conducted using more restrictive algorithms for SRSE.

Results: A total of 6,325 hospital discharges were classified as SRSE cases from a total of 5,300,000 hospital discharges. Applying a weighting based on hospital characteristics and 2012?US demographics, this projected to an estimated 41,156 cases of SRSE in the US during 2012, an estimated incidence rate of ～13/100,000 annually for SRSE in the US. Secondary analyses using stricter SRSE algorithms resulted in estimated incidence rates of ～11/100,000 and 8/100,000 annually. The mean LOS for SRSE hospitalizations was 16.5 days (median =11; interquartile range [IQR]?=?6–20), and the mean ICU LOS was 9.3 days (median =6; IQR =3–12). The mean cost of an SRSE hospitalization was $51,247 (median = $33,294; 95% CI = $49,634–$52,861).

Limitations: The analysis uses ICD-9 diagnostic codes and claims information, and there are inherent limitations in any methodology based on treatment protocol, which created challenges in distinguishing with complete accuracy between SRSE, RSE, and SE on the basis of care patterns in the database.

Conclusion: SRSE is associated with high mortality and morbidity, which place a high burden on healthcare resources. Projections based upon the findings of this study suggest an estimated 25,821–41,959 cases of SRSE may occur in the US each year, but more in-depth studies are required.     

Customer orientation,engagement, and developing positive emotional labor

Frontline employees must deal on a daily basis with emotionally demanding customer interactions. Such interactions, when coupled with organizational directives to focus upon exemplary customer service, can prompt employees to express feelings and emotions that are not genuine. Such ‘surface acting' has been found to create stress in frontline personnel, but an understanding of how this negative aspect of emotional labor may be minimized is lacking in the services literature. How a frontline employee's individual attributes might interact with a service work context to build deep, as opposed to surface, acting is the current focus. Applying job demands–resources theory, this study investigates how a frontline employee's customer orientation helps to develop positive work engagement, even in the face of contextual demands. Engagement is then linked positively to the beneficial behavior of deep acting which, in contrast to surface acting, has been identified as a less stressful form of emotional labor.     

Consumer Valuation of Environmentally Friendly Production Practices in Wines,considering Asymmetric Information and Sensory Effects

Agricultural producers and food marketers are increasingly responding to environmentally friendly cues from consumers, even though privately appropriated values associated with a range of food products commonly rank above their public‐good counterparts. Wine can be considered an ideal product to examine these issues given consumers’ highly subjective sensory preferences towards wine, and a winegrape production process that is relatively intensive in the use of chemical inputs for the control of disease and infection. Semi‐dry Riesling wines made from field research trials following environmentally friendly canopy management practices were utilised in a lab experiment to better understand preferences for environmental attributes in wine. A combined sensory and monetary evaluation framework explicitly considered asymmetric order effects. Empirical results revealed that sensory effects dominate extrinsic environmental attributes. Once consumer willingness to pay (WTP) was conditioned on a wine’s sensory attributes, the addition of environmentally friendly information did not affect their WTP; however, adding sensory information significantly influenced WTP initially based only on environmental attributes. The results confirm the idea that promoting environmentally friendly winegrape production practices would increase demand and lead to higher premiums for the products, but are only sustainable if consumers’ sensory expectations are met on quality.     

Institutions and concentration

In a new dataset of 1.3 million firms from over 100 countries, I establish a number of regularities in cross-country differences in economic concentration. Concentration of sales and employment is substantially higher in smaller countries and in less-developed countries; these two factors alone explain roughly half the cross-country variation in concentration. Nevertheless, a number of institutional factors offer additional explanatory power for concentration. Concentration is higher in countries with higher entry costs for new firms, in countries with weaker antitrust policy, in countries with less financial development, in countries with weaker rule of law, and in countries with more burdensome regulation. Weak institutions are associated with higher concentration especially in industries that do not have naturally high levels of concentration. In addition, the relationships between institutions and concentration are more pronounced in nontradable and investment-intensive industries, suggesting that natural barriers to competition facilitate the monopolization of sectors especially when institutions are weak.     

Self-interest, sympathy and the origin of endowments

We explore whether the recent laboratory findings that suggest the origin of endowment matters in simple bargaining games are actually due to contextual shifts of relative effort and deservingness. Results support previous findings of endowment origin yielding more self-interested behavior.     

Perceptions of Affirmative Action Based on Socioeconomic Status: A Comparison with Traditional Affirmative Action

Past research has examined reactions to traditional, gender- and ethnicity-based affirmative action programs. However, research has not examined reactions to affirmative action based on socioeconomic status (SES), even though such programs are promoted by the U.S. government (e.g., Work Opportunity Tax Credit) and thus act as a de facto supplement to traditional affirmative action. Based in theories of self-interest, Study 1 compared reactions of men and women to a traditional affirmative action program and a hypothetical, SES-based affirmative action program in terms of general perceptions of such programs and organizational attractiveness. While women had more positive reactions to traditional affirmative action, men had more positive reactions to SES-based affirmative action. Study 2 took a different approach, examining the reactions of potential job applicants to four hypothetical job ads which included different types of diversity statements. We found that job ads that mentioned any type of specific diversity statement - either based on race and gender or based on SES - were perceived as less fair than job ads that did not include specific diversity statements. Results of the studies are discussed in terms of self-interest theories of affirmative action and considerations of SES-based programs as a supplement to traditional affirmative action.
