Is it the weather?

We show that results in the recent strand of the literature, which tries to explain stock returns by weather induced mood shifts of investors, might be data-driven inference. More specifically, we consider two recent studies [Kamstra, Mark J., Kramer, Lisa A., Levi, Maurice D., 2003a. Winter blues: A SAD stock market cycle. American Economic Review 93(1), 324–343; Cao, Melanie, Wei, Jason, 2005. Stock market returns: A note on temperature anomaly. Journal of Banking and Finance 29(6), 1559–1573] that claim that a seasonal anomaly in stock returns is caused by mood changes of investors due to lack of daylight and temperature variations, respectively. While we confirm earlier results in the literature that there is indeed a strong seasonal effect in stock returns in many countries: stock market returns tend to be significantly lower during summer and fall months than during winter and spring months as documented by Bouman and Jacobsen [Bouman, Sven, Jacobsen, Ben, 2002. The Halloween indicator, Sell in May and go away: Another puzzle. American Economic Review, 92(5), 1618–1635], there is little evidence in favor of a SAD or temperature explanation. In fact, we find that a simple winter/summer dummy best describes this seasonality. Our results suggest that without any further evidence the correlation between weather-related variables and stock returns might be spurious and the conclusion that weather affects stock returns through mood changes of investors is premature.     

Is it the weather? Comment

This comment discusses some errors in a recent paper by Jacobsen and Marquering [Jacobsen, B., Marquering, W., 2008. Is it the weather? Journal of Banking and Finance 32 (4), 526–540], in which the authors challenge our previous finding that stock market returns exhibit seasonal patterns consistent with the influence of seasonal affective disorder on investor risk aversion. We find that we cannot replicate the authors’ findings, even after corresponding with them. Furthermore, we document several problems with their methodology, including misspecification of their economic model, misspecification of their econometric model, and use of inappropriate data. While we agree that seasonal affective disorder is not an explanation for all variation in equity markets, we do maintain that careful analysis leads to economically and statistically significant evidence of the effect we originally documented.     

Is it the weather? Response

Kamstra, Kramer and Levi (KKL) in their comment seem to miss the main point of our paper. Many things are correlated with the seasons so it is difficult to distinguish between them when we try to explain the well-known summer winter pattern in stock returns. Finding an isolated seasonal affective disorder (SAD) effect without proper control variables does not disprove our point but strengthens it. To sidestep all of the issues they raise and take our point to the extreme, we show using plain vanilla regressions that the seasonal stock market pattern they attribute to SAD can also be “explained” by variables like ice cream consumption or airline travel. The new variations of SAD variables (“onset” and “incidence”) KKL propose in their recent work for North America are even more problematic than the original SAD variables. We find that these new SAD proxies are not significant in countries where according to KKL they should be: Canada and the United States.     

FASB's conceptual framework: Is it being taught?

FASB conceptual framework supporters suggest that the future acceptance of the framework by the accounting profession is dependent in part upon student classroom exposure to the framework. This study surveyed intermediate accounting professors to determine if this exposure is occurring. Survey results suggest that the framework is frequently discussed-but normally at a superficial level. The study also attempted to develop a profile of teachers who emphasize the framework. No associations were found when testing for individual characteristics. However, an association was found between those identified as substantive framework professors and respondents from programs which allot more than six semester credit hours for the intermediate accounting sequence as well as these programs which offer undergraduate theory courses.     

Accounting information systems research: Is it another QWERTY?

This article examines the research within accounting information systems (AIS) as found in articles published in leading accounting, management information systems, and computer science journals from 1982 to 1998. Trend analysis is performed on AIS articles found in the following journals: The Journal of Information Systems; Advances in Accounting Information Systems; Journal of Accounting Research; The Accounting Review; Journal of Accounting and Economics, Accounting, Organizations and Society, Auditing: A Journal of Practice and Theory; Behavioral Research in Accounting; Journal of Management Accounting Research; Management Science; MIS Quarterly; Decision Sciences; Information Systems Research; and Communications of the ACM, among others. The trend analysis is structured across underlying theory, research method, and information systems lifecycle topics of AIS articles in these journals. This article identifies the extant research streams in AIS, where AIS research has been published from 1982 to 1998, and seeks to provide insight into the question: should AIS exist as its own separate research domain? Is AIS research like the QWERTY keyboard (David, 1985), widely adopted due to popular demand, but ineffective and inefficient, with a better AIS research and teaching model available?     

Is it all about awareness? The normalization of coastal risk

Coastal risk is already high in several parts of the world and is expected to be amplified by climate change, which makes it necessary to outline effective risk management strategies. Risk managers assume that increasing awareness of coastal risk is the key to public support and endorsement of risk management strategies – an assumption that underlies a common worldview on the public understanding of science, which has been named the deficit model. We argue that the effects of awareness are not as straightforward. In particular, awareness of coastal hazards might not lead to more technically accurate risk perceptions. Based on research on risk perception normalization, we explored the hypothesis that coastal risk awareness reduces coastal risk perception – in particular the perceived likelihood of occurrence of coastal hazards – through its effect on reliance on protective measures to prevent risk. Individuals can rely on protective measures, even when those are not effective, as a positive illusion to reduce risk perception. This effect might be stronger for higher probability hazards and for permanent residents of costal zones. Data from 410 individuals living in coastal zones corroborated most of our expectations. Global results demonstrated a risk normalization effect mediated by reliance on current measures. Additional analyses made clear that this effect occurred in 2 of the 5 high-probability hazards (flood and storm), and not in the low-probability hazard (tsunami). Normalization might be more likely among high-probability hazards which entail catastrophic and immediate impacts. This effect was also found among permanent residents, but not among temporary residents. Results imply that coastal risk management might benefit from (a) taking risk perception normalization effects into account, (b) tailoring strategies for permanent and temporary residents and (c) promoting a higher public engagement, which would facilitate a more adaptive and effective coping with coastal risk than the use of positive illusions.     

Is it costly to be both shariah compliant and socially responsible?

Positive ethics associated with socially responsible investments (SRI) is challenging the limits of Islamic investments' conservative approach to promote corporate social responsibility. In this study, we test the integration of social performance measures (companies the most virtuous or high-rated in terms of environmental, social, and governance (ESG) issues) in Islamic portfolios using KLD social ratings. We seek to determine the financial price of complying both to Islamic investment and SRI principles. To do so, we measure the financial performance of self-composed Islamic portfolios with varying ESG scores. The results indicate no adverse effects on returns due to the application of ESG screens on shariah-compliant stocks during the 2007–2011 periods while reporting substantially higher performance for the portfolios with good records in governance, products, diversity, and environment issues. On the opposite, a negative performance is associated with an SRI strategy of disengagement from shariah-compliant stocks with community and human rights controversies. Our performance measures are controlled for market sensitivity, investment style, momentum factor, and sector exposure.     

Socially responsible investing: Is it for real or just for show?

Many mutual funds declare themselves as socially responsible investment (SRI) funds. However, it is unclear whether this rhetoric is simply window-dressing to attract capital inflows or reflects genuine concern. We show that companies with better environmental, social, and governance (ESG) performance are more attractive to SRI mutual funds. More importantly, SRI mutual funds positively affect their investee firms' ESG performance after controlling for firm characteristics, possible endogeneity issues, and omitted variables. Furthermore, ownership structure, board members' international experience, and social media attention are important channels through which SRI mutual funds influence their investee firms' ESG performance.     

The South Pacific Stock Exchange: Is it a Market or Status Symbol?

Listing on a stock exchange is one of the most significant events in a company's life cycle. Using a case study approach we examine why companies in Fiji list on a stock exchange. The various factors that have been found to motivate companies to list include enhancing their image and reputation, increasing the firm's value and introducing better financial and managerial practices. Importantly, the accessing of new sources of finance has not been a determinant of a company's listing decision. The findings imply that in emerging economies, stock exchange listing can be perceived as a status symbol .     

Long-term negative fund alpha: Is it caused by bad skill or bad luck?

This paper examines the sources of long-term negative fund alpha. We compare the actual loser funds with a control group of bootstrapped loser funds. We find that the returns of the two fund groups are co-integrated, and that they are similar in market risk exposure, alpha consistency, portfolio holdings, and GARCH volatility. The test results show that long-term negative fund alpha occurs due to bad luck rather than to bad skill.     

Authenticity: is it real or is it marketing?

Marty Echt, the new head of marketing at Hunsk Engines, is determined to bring the motorcycle maker back to its roots. He says it's not enough to project authenticity to customers--employees must personally subscribe to the brand's values. Should the company's CEO support Marty's "real deal" vision? Five experts comment on this fictional case study. Bruce Weindruch, the founder and CEO of the History Factory, says that an authenticity-based campaign can be effective--but only if it's truly drawn from history. Marketers like Marty often remember their organization's past in a golden haze. Weindruch recommends exploring old engineering drawings, ads, and product photos in order to understand what customers and employees really valued back in the day. Gillian Arnold, a consultant to luxury fashion and fine jewelry brands, thinks Marty's approach is right: People in key marketing posts must be passionate about their products and know them inside and out. She argues that the CEO needs to commit more fully to the new campaign and address the significant gap between the staff and the brand. James H. Gilmore and B. Joseph Pine II, the cofounders of Strategic Horizons, point out that Hunsk needs to manage customers' perceptions rather than trying to be a "real company" or forming a management team whose personal interests match the brand. People purchase a product if it conforms to their self-image; that alone determines the brand's authenticity. Glenn Brackett of Sweetgrass Rods, a maker of bamboo fly-fishing rods, says Marty seems to be one of the few people who understand Hunsk motorcycles. If employees bring blood, sweat, heart, and soul to a product, it will manifest that spirit, and customers will line up for it.     

Is it Shameful to be an Accountant? GenMe Perception(s) of Accountants' Ethics

The function that accountants fulfil in the economic system is dependent on their ability to maintain the perception of high ethical standards. Building on the idea that birth cohorts, otherwise known as generations, are a useful proxy for the socio‐cultural environment of different time periods, we focus on the so‐called ‘GenMe’, that is, students and young workers born in the 1980s and 1990s. In particular, combining the accounting and business ethics literature, the purpose of our paper is to contribute to an increased awareness of the GenMe perceptions of accountants, with special attention given to ethical aspects. We believe that the perceptions of this age group are particularly crucial for the future of the accounting profession as it is these young people who will either become professional accountants or the accountants' future clients. Using an extensive database of 1,794 questionnaires, results show that the impression of the accountant as a corrupt professional is not dominant among GenMe and seem to suggest the existence of a multifaceted perception of accountants' ethics. Specifically, the factors that contribute to influencing GenMe perceptions of accountants' ethics are level of education, having attended an accounting course at high school level, gender, and belonging to the accounting profession. Finally, our study indicates that there is room for improving public perceptions of accountants' ethics through university courses in ethics, continuing education programs, and focused communication strategies by accounting firms and professional bodies.     

Flexible inflation targeting and financial stability: Is it enough to stabilize inflation and output?

We investigate empirically whether a central bank can promote financial stability by stabilizing inflation and output, and whether additional stabilization of asset prices and credit growth would enhance financial stability in particular. We employ an econometric model of the Norwegian economy to investigate the performance of simple interest rate rules that allow a response to asset prices and credit growth, in addition to inflation and output. We find that output stabilization tends to improve financial stability. Additional stabilization of house prices, equity prices and/or credit growth enhances stability in both inflation and output, but has mixed effects on financial stability. In general, financial stability as measured by e.g., asset price volatility improves, while financial stability measured by indicators that depend directly on interest rates deteriorates, mainly because of higher interest rate volatility owing to a more active monetary policy.     

Liquidity Crunch in the Interbank Market: Is it Credit or Liquidity Risk, or Both?

The interplay between liquidity and credit risks in the interbank market is analyzed. Banks are hit by idiosyncratic random liquidity shocks. The market may also be hit by bad news at a future date, implying the insolvency of some participants and creating a lemons problem; this may end up with a gridlock of the interbank market at that date. Anticipating such possible contingency, banks currently long of liquidity ask a liquidity premium for lending beyond a short maturity, as a compensation for the risk of being short of liquidity later and being forced to liquidate some illiquid assets. When such premium gets too high, banks currently short of liquidity prefer to borrow short term. The model is able to explain some stylized facts of the 2007–2009 liquidity crunch affecting the money market at the international level: (i) high spreads between interest rates at different maturities; (ii) “flight to overnight” in traded volumes; (iii) ineffectiveness of open market operations, leading the central banks to introduce some relevant innovations into their operational framework.     

Is hospital competition wasteful?

Recent attention has been given to the hypothesis that local hospital competition takes the form of costly duplication of specialized services--the "medical arms race." This contrasts with the hypothesis that the supply of specialized services is determined solely by "the extent of the market." We develop a model predicting the provision of specialized services in local markets. Our analysis of California hospitals provides minimal support for the medical arms race hypothesis while suggesting substantial scale economies for many services. Our results emphasize the importance of properly specifying the extent of the market. Failure to do so leads one to overestimate the importance of competition.     

Is Chapter 11 Efficient?

The efficiency of the Chapter 11 bankruptcy process is examined by estimating the impact of Chapter 11 filings on the operating performance of bankrupt firms. We control for firm‐level heterogeneity in prefiling characteristics using matching methods to select benchmark firms comparable to filing firms. We compare bankrupt firms’ operating performances with those of matched nonbankrupt firms. Our results challenge the contention that Chapter 11 is an inefficient, debtor‐friendly mechanism that rehabilitates economically nonviable firms. We demonstrate that firms that file under Chapter 11 perform no worse and, if anything, better than comparable nonfiling firms.     

What Is Systemic Risk?

The traditional view of risk in a financial system is that it is the summation of individual risks within the system. However, the financial crisis that started in 2007 has driven home that this view of risk is inadequate. It is the interactions of financial institutions and markets that determine the systemic risks that drive financial crises. We identify four types of systemic risk. These are (i) panics—banking crises due to multiple equilibria; (ii) banking crises due to asset price falls; (iii) contagion; and (iv) foreign exchange mismatches in the banking system.     

How does managed care do it?

Integrating the health services and insurance industries, as health maintenance organizations (HMOs) do, could lower expenditure by reducing either the quantity of services or unit price or both. We compare the treatment of heart disease in HMOs and traditional insurance plans using two datasets from Massachusetts. The nature of these health problems should minimize selection. HMOs have 30% to 40% lower expenditures than traditional plans. Both actual treatments and health outcomes differ little; virtually all the difference in spending comes from lower unit prices. Managed care may yield substantial increases in measured productivity relative to traditional insurance.
