This paper examines the value effect of working capital management (WCM) for a large sample of US firms over the period 1982-2011. Taking into account omitted variables and reverse causality, we show that the decrease in working capital across time leads to increasing performance. This relationship is driven by firms that have substantial cash unnecessarily tied up in working capital. Importantly, we also show that corporate investment is the channel through which improvement in WCM translates into superior performance. Finally, the value effect of WCM is attenuated during the financial crisis, due to the contraction of the investment opportunity set.

We provide new evidence on the role of financial advisors in M&As. Contrary to prior studies, top-tier advisors deliver higher bidder returns than their non-top-tier counterparts but in public acquisitions only, where the advisor reputational exposure and required skills set are relatively larger. This translates into a $65.83 million shareholder gain for an average bidder. The improvement comes from top-tier advisors' ability to identify more synergistic combinations and to get a larger share of synergies to accrue to bidders. Consistent with the premium price-premium quality equilibrium, top-tier advisors charge premium fees in these transactions.MERGERS AND ACQUISITIONS (M&As) constitute one of the most important activities in corporate finance, bringing about substantial reallocations of resources within the economy. In 2007 alone, when the most recent merger wave peaked, corporations spent $4.2 trillion on M&A deals worldwide. Investment banks advised on over 85% of these deals by transaction value, generating an estimated $39.7 billion in advisory fees.

"We examine whether acquisitions by overconfident managers generate superior abnormal returns and whether managerial overconfidence stems from self-attribution. Self-attribution bias suggests that overconfidence plays a greater role in higher order acquisition deals predicting lower wealth effects for higher order acquisition deals. Using two alternative measures of overconfidence (1) high order acquisition deals and (2) insider dealings we find evidence supporting the view that average stock returns are related to managerial overconfidence. Overconfident bidders realise lower announcement returns than rational bidders and exhibit poor long-term performance. Second, we find that managerial overconfidence stems from self-attribution bias. Specifically, we find that high-order acquisitions (five or more deals within a three-year period) are associated with lower wealth effects than low-order acquisitions (first deals). That is, managers tend to credit the initial success to their own ability and therefore become overconfident and engage in more deals. In our analysis we control for endogeneity of the decision to engage in high-order acquisitions and find evidence that does not support the self-selection of excessive acquisitive firms. Our analysis is robust to the influence of merger waves, industry shocks, and macroeconomic conditions." Copyright 2007 The Authors Journal compilation (c) 2007 Blackwell Publishing Ltd.

Using a global M&A data set, this paper provides evidence that the empirical observations relating public acquisitions to, at best, zero abnormal returns, and their stockfinanced subset to negative abnormal returns for acquiring firms around the deal announcement are not unanimous across countries. Acquirers beyond the most competitive takeover markets (the U.S., U.K., and Canada) pay lower premia and realize gains, while share-for-share offers are at least non-value destroying for their shareholders. In contrast, target shareholders within these markets gain significantly less, implying that the benefits generated are more evenly split between the involved parties.

Cash holding is on average more valuable when firms are managed by overconfident CEOs. Economically, having an overconfident CEO on board is associated with an increase of $0.28 in the value of $1.00 cash holding. The positive effect of CEO overconfidence on the value of cash concentrates among firms that are more likely to suffer from the underinvestment problem (i.e., financially constrained firms which exhibit high growth opportunities). In addition, CEO overconfidence affects negatively the value of cash in firms that are financially unconstrained, a finding which is consistent with the overinvestment hypothesis. The results are robust to various tests and alternative explanations.

This paper generates short-term forecasts on tourist arrivals in Greece and performs impulse response analysis to measure the impact of macroeconomic shocks from the origin country on future tourism demand. We find the ARIMA (1, 1, 1) model outperforms exponential smoothing models in forecasting the direction of one year out of sample forecasts. However, this does not translate into point forecasting accuracy. Impulse response analysis on the impact of unemployment and tourists' cost of living shocks shows that the source of downside risk to future tourism numbers is limited in scope, magnitude, and duration. Shocks to consumer confidence from the origin countries have no impact on future tourism demand. Our results offer important insights and implications for policymakers and tourist operators.

We examine shareholders' wealth effects (both in the short- and the long-run) of UK frequent bidders acquiring public, private, and/or subsidiary targets with alternative methods of payment between 1987 and 2004. We find that, in the short-run, bidders break even when acquiring public targets and gain significantly when buying private and subsidiary targets. This result is robust after controlling for relative size, bidder's book-to-market ratio, target origin, and industry diversification. Our long-run evidence, however, reveals that acquirers experience, significant wealth losses regardless of the target type acquired, indicating that markets may initially overreact to the acquisition announcement. As a result, we argue that contrary to Fuller et al. (2002) who suggest that acquiring private and subsidiary firms creates value for bidding firms, a reliable conclusion on bidders' shareholders wealth effects cannot be based solely on a short-run event study.
