Re-examining the risk–return relationship in banks using quantile regression

Financial data for the US banks listed during 2001–2007 are analysed to re-examine the risk–return relationship in the banking industry. A key feature of this study is the analysis of the changing distribution of return on equity across banks and over time by the quantile regression (hereafter QR) model and a meaningful comparative analysis with the results of the ordinary least squares estimates is examined. The following conclusions are drawn from the empirical results. First, while a positive risk–return relationship is presented for the profitable banks, the risk–return relationship is negative for the profitless banks. Second, the ‘V’ shape relationship between bank risk and profitability identified by this study could satisfactorily explain the existing risk–return puzzle among the prior empirical studies.     

Market Conditions and Abnormal Returns of IPO–An Empirical Study of Taiwan's High-Tech Companies

Four new determinants of initial/long-run IPO (initial public offering) returns from the perspectives of market conditions are proposed in this paper. The associated effects are examined by using the samples of Taiwan's high-tech IPO companies. Our empirical findings are consistent with the following notions. First, the four new determinants proposed perform remarkable effects on the IPO returns. Second, the length for IPO and IPO clustering phenomena has notable impacts on the long-run returns of IPO. In contrast, the performances of public stock markets show significant effects on the initial returns of IPO.     

The psychological impact of teleworking: stress, emotions and health

The paper examines the psychological impact of teleworking compared to office-based work. Results suggest a negative emotional impact of teleworking, particularly in terms of such emotions as loneliness, irritability, worry and guilt, and that teleworkers experience significantly more mental health symptoms of stress than office-workers and slightly more physical health symptoms.

Post-IPO Operating Performance, Venture Capital and the Bubble Years

Abstract:  We analyse the post-issue operating performance of 316 venture-backed and 274 non-venture UK IPOs 1985–2003. The finding of a statistically significant five-year, operational decline exhibited over the full sample period is not robust. Rather it is driven by the dramatic underperformance during the 1998–2000 bubble years while IPOs perform normally in the remaining years. Cross-section regression results indicate support for venture capital certification in the non-bubble years but a significantly negative relationship between operating performance and venture capitalist board representation during the bubble years. The bubble year underperformance is explained by market timing and by low quality companies taking advantage of investor sentiment.     

Sectoral Patterns of Interactive Learning: An Empirical Exploration of a Case in a Dutch Region

This paper pursues the development of a theoretical framework that explains interactive learning between innovator firms and external actors in both the knowledge infrastructure and the production chain. The research question is: What kinds of factors explain the interactive learning of innovator firms with distinct external actors? Our theoretical framework extends the resource-based perspective, which is predominant in network theory, with both an activity-based and a structural account of interactive learning. We contend basically that higher technological dynamics induce more complex innovative activities. But, more complex innovative activities increase the probability of internal resource deficits/shortages in the innovator firms. The lower the alignment of the innovative activities with the quality of the internal resource base, the higher the resource deficits/shortages and the more likely the search for complementary resources externally, which increases the likeliness of external relationships. In order to test the generality of our theoretical claims we analyse our models in four sectors with distinct technological dynamics as distinguished by Pavitt. For each sector we explore five models of the level of interactive learning of innovator firms with: (1) the public knowledge infrastructure (difficult to access, demands high internal competencies to utilize scientific knowledge), (2) the production chain (easy to access), (3) their users, (4) their suppliers, (5) their competitors. These analyses allow for a comparison between interactive learning with different external actors and give deeper insights into the differentiated interaction patterns involving innovation. Our findings show that patterns of interactive learning between sectors differ. Some are more resource based and others are more affected by the complexity of innovative activities. Particularly the patterns of interactive learning between, on the one hand, firms and the knowledge infrastructure, and on the other hand of firms with the production chain show important differences.
