A polymorphism associated with entrepreneurship: evidence from dopamine receptor candidate genes

The tendency to be an entrepreneur may be influenced by genetic variation. Sensation seeking is more common among entrepreneurs than among the general population. Twin studies show that the tendency to be an entrepreneur is heritable and that common genes influence both sensation seeking and entrepreneurial tendency (Nicolaou et al. Manag Sci 54:167–179, 2008a; Strateg Entrep J 2:7–21, 2008b). Since dopamine receptor genes have been associated with novelty seeking/sensation seeking (Benjamin et al. Nat Genet 12:81–84, 1996; Ebstein et al. Nat Genet 12:78–80, 1996; Noblett and Coccaro Curr Psychiatry Rep 7:73–80, 2005), and attention deficit hyperactivity disorder (ADHD) has been reported to occur at greater rates among entrepreneurs, we examined the association between five dopamine receptor genes and four ADHD-associated genes, with the tendency to be an entrepreneur in a sample of 1,335 individuals from the UK. We found a single nucleotide polymorphism (rs1486011) of the DRD3 gene on chromosome 3 to be significantly associated with the tendency to be an entrepreneur. This result is the first evidence of the association of a specific gene with entrepreneurship. Further studies are needed to replicate this association.     

Do Mutual Fund Investors Care About Auditor Quality?

We study the influence of perceived auditor quality on investment decisions by bond mutual fund investors. Audits of bond mutual funds require significant auditor expertise. Fund managers estimate daily the fair market values of holdings that are often opaque and illiquid. Managers can use their discretion to manipulate their fund's performance results. While it is known that investment flows into funds that report good past performance, little evidence exists about whether investors' confidence in the reliability of fund financial reports is influenced by auditor quality. Using hand‐collected data from SEC filings, we find that the positive association between reported performance and investment flows is stronger for funds with auditors who are industry specialists and are longer‐tenured, as well as for funds that pay higher audit fees. We do not find that auditor office size strengthens the association. We also find that the presence of industry‐specialist auditors, long‐tenured auditors, and higher audit fees lead to additional disclosure in the form of emphasis‐of‐matter. This study contributes to the streams of research investigating perceived audit quality, fund investment decisions, and auditing for financial services.     

Do corporate payouts signal going-concern risk for auditors? Evidence from audit reports for companies in financial distress

We examine the association between payout policy changes and going-concern decisions for financially distressed clients. Extant auditing standards indicate that payout reductions, which offer a prospect of short-term cash relief, can potentially mitigate going-concern uncertainty, whereas economic theory suggests payout decreases (increases) convey mixed but mostly negative (positive) signals about a company’s future financial status. We find that, compared with a bankruptcy prediction model over short (not to exceed 1 year) and long (2–3 years) horizons, auditors seem to significantly underreact to payout decreases (i.e., negative signals) but react appropriately to payout increases (i.e., positive signals) in their going-concern decisions. Moreover, auditors are three times more likely to make Type II misclassification errors in payout-decreasing firms than in payout-increasing and no-change firms. We also find that auditors take longer to determine the appropriate opinion for clients with payout changes, especially for those who cut their payouts. Overall, our findings suggest that auditors respond differently to positive and negative signals about companies’ future prospects, reflecting the mixed nature of payout decreases relative to payout increases and the professional standards’ emphasis on the prospect of short-term cash relief from payout reductions.     

Additional cautionary notes about the Pearson's correlation coefficient

In this paper we draw attention to two usually-neglected problems with the use of the Pearson's correlation coefficient for ordinal scores. We refer to the questions of substantial differences between the marginal distributions of the two variables to be correlated, and the number of ties on each one of the distributions or on both. Finally, we propose a correction factor for the Pearson's correlation coefficient when the number of ties is large. Some empirical examples are given in order to demonstrate these points.

Spatial competition and agglomeration in the visitor attraction sector

This paper provides a theoretical and empirical contribution to understanding spatial competition by examining visitor attractions in two contrasting clusters of lower and higher levels of agglomeration of businesses in Cornwall, UK. The study found that competition is mainly for customers and labour and is related differently to the levels of agglomeration, spatial proximity and thematic product similarity between visitor attractions at the local compared with the regional scale. Location can be used differently for employing ‘weak’ and ‘strong’ competitive strategies. The study contributes to the knowledge on the spatiality of competition and the locational strategies of service businesses.     

Returns to IT excellence: Evidence from financial performance around information technology excellence awards

The resource-based view has been used in IT business value research to theorize and investigate the impact of unique IT capabilities on sustainable competitive advantages. Prior research has empirically documented a positive association between superior IT capabilities and firm performance. However, such analyses have focused on IT capabilities of firms in the early 1990s. In this study, we examine the impact of superior IT capabilities on firm performance over the 1988–2007 period, which allows us to consider the structural shifts in the return of IT capability over time. Our results suggest that firms with superior IT capabilities are able to attain higher firm performance levels until 1999. However, such performance advantage disappears in the post-1999 time period. We also find that a subset of firms that sustain high levels of IT capabilities during the period 1988 to 2007 continue to perform better than their peers. We conclude that managers are able to achieve superior firm performance if they are able to maintain high levels of IT capability over time.     

The association between characteristics of audit committee accounting experts,audit committee chairs,and financial reporting timeliness

We investigate the association between audit committee (AC) members' financial expertise and financial reporting timeliness, and extend the discussion by investigating how the source of accounting expertise (e.g., public accounting or CFO) differentially influences financial reporting timeliness. We predict and find that AC accounting financial expertise is associated with timelier accounting information. Further, we find that accounting expertise gained from public accounting experience is associated with timelier financial reporting; however, accounting expertise gained from CFO experience is not. We also find that AC chairs (ACCs) with accounting expertise from public accounting experience are significantly associated with timelier financial reporting while ACCs with CFO-sourced accounting expertise are not. Our results are important for two reasons. First, our results suggest that AC accounting financial expertise contributes to AC effectiveness by improving the timeliness of financial information. Second, our findings highlight how personal characteristics of accounting financial experts influence contributions toward AC effectiveness.     

An Empirical Analysis of a Regional Dutch Disease: The Case of Canada

While there has been extensive research on the Dutch Disease (DD), very little attention, if any, has been devoted to the regional mechanisms through which it may manifest itself. This is the first empirical attempt to research a ‘regional DD’ by looking at the local and spatial impacts of resource windfalls across Canadian provinces and territories. We construct a new panel dataset to examine separately the key DD channels; namely, the Spending Effect and the Resource Movement Effect. Our analysis reveals that the standard DD mechanisms are also relevant at the regional level; specifically, we find that: (a) Resource windfalls are associated with higher inflation and a labour (capital) shift from (to) non-primary tradable sectors. (b) Resource windfalls in neighbouring regions are associated with a capital (labour) shift from (to) non-primary tradable sectors in the source region. (c) The (spatial) DD explains (51  %) 20  % of the adverse effects of resource windfalls (in neighbouring regions) on region-specific non-mineral international exports (in the source region), and does not significantly affect domestic ones.
