Alliance formation is commonplace in many high‐technology industries experiencing radical technological change, where established firms use alliances with new entrants to adapt to technological change, while new entrants benefit from the ability of established players to commercialize the new technology. Despite the prevalence of these alliances, we know little about how these firms choose to ally with specific firms given the range of possible partners they may choose from. This study explores factors that lead to alliance formation between pharmaceutical and biotechnology companies. We focus on the alliance tie as the unit of analysis and argue that dyadic complementarities and similarities directly influence alliance formation. We then introduce a contingency model in which the positive effect of complementarities and similarities on alliance formation is moderated by the age of the new technology firm. We draw theoretical attention to the intersection between levels of analysis, in particular, the intersection between dyadic and firm‐level constructs. We find that a pharmaceutical and a biotechnology firm are more likely to enter an alliance based on complementarities when the biotechnology firm is younger. Another noteworthy finding is that proxies for broad capabilities appear to be at least as effective, if not more so, in predicting alliance formation compared to fine‐grained science and technology‐related indicators, like patent cross‐citations or patent common citations. We conclude by suggesting that future studies on alliance formation need to take into account interactions across levels; for example, how dyadic capabilities interact with firm‐level factors, and the advantages and disadvantages of more or less fine‐grained measures of organizational capabilities.

In recent months, the list of large diversified companies that have decided they would be worth more as several smaller, focused companies has grown sharply. In many of these cases, it has been outside pressure from activist investors that has motivated these actions by management—and with some pretty favorable results. But what is driving these strategic actions and what is most important in determining whether breakups create value? To answer this fundamental questions, it is critical to decide whether large, diversified companies have a value recognition problem or a value creation problem. In this article, the authors present and try to integrate the findings of two separate but related research studies on business diversity and size with the aim of identifying their implications for corporate strategy and helping company executives create more value for their investors. The specific reasons for underperformance by large diverse companies vary greatly, but there are a number of potential problems discussed in this article, including organizational “distance,” capital allocation, human capital allocation, cross subsidies, and ineffective governance. Instead of waiting for activist investors to demand a breakup, executives of large diverse companies should be proactive in addressing the potential weaknesses of their organizations. Private equity firms understand how to make diversification work and many of today's executives could learn some valuable lessons from these firms. Large diverse businesses should embrace “Internal Capitalism,” a corporate culture and set of practices that emphasizes the importance of strategic decision‐making that is linked through continuous performance assessment to the corporate goals of boosting efficiency and sustainable growth. 相似文献

We investigate the number of and reasons for errors and questionable judgments that sell-side equity analysts make in constructing and executing discounted cash flow (DCF) equity valuation models. For a sample of 120 DCF models detailed in reports issued by U.S. brokers in 2012 and 2013, we estimate that analysts make a median of three theory-related and/or execution errors and four questionable economic judgments per DCF. Recalculating analysts’ DCFs after correcting for major errors changes analysts’ mean valuations and target prices by between ?2 and 14 % per error. Based on face-to-face interviews with analysts and those who oversee them, we conclude that analysts’ DCF modeling behavior is semi-sophisticated in the sense that analysts genuinely make mistakes regarding certain aspects of correctly valuing equity but also respond rationally to the incentives they face, particularly the reality that they are not directly compensated for being textbook DCF correct. 相似文献

Most mortality models proposed in recent literature rely on the standard ARIMA framework (in particular: a random walk with drift) to project mortality rates. As a result the projections are highly sensitive to the calibration period. We therefore analyse the impact of allowing for multiple structural changes on a large collection of mortality models. We find that this may lead to more robust projections for the period effect but that there is only a limited effect on the ranking of the models based on backtesting criteria, since there is often not yet sufficient statistical evidence for structural changes. However, there are cases for which we do find improvements in estimates and we therefore conclude that one should not exclude on beforehand that structural changes may have occurred. 相似文献

One of the recommendations of The Pathways Commission report was to increase the number of diverse entrants into the accounting profession. While the Commission’s recommendation is commendable, the lack of diversity in the accounting profession is not a new problem. Hence, the accounting profession has attempted to address the underrepresentation of minority Certified Public Accountants (CPAs) for many years. To this end, organizations such as American Institute of CPAs (AICPA), National Association of Black Accountants (NABA), Association of Latino Professionals in Finance and Accounting (ALPFA), and the Ph.D. Project have provided different types of support to alleviate the problem. However, the numbers are still disturbingly low. This is particularly true for Hispanic accountants. Therefore, the purpose of this study was to examine Hispanic accountants’ perception of the CPA credential. While the results indicate that gender, exam affordability, and job incentives are positively associated with the likelihood of being a CPA, the 150-hour requirement was not perceived as a hindrance for certification. 相似文献

Climate Change and Asset Prices: Are Corporate Carbon Disclosure and Performance Priced Appropriately? 下载免费PDF全文
Andrea Liesen Frank Figge Andreas Hoepner Dennis M. Patten 《Journal of Business Finance & Accounting》2017,44(1-2):35-62
This paper empirically assesses the relevance of information on corporate climate change disclosure and performance to asset prices, and discusses whether this information is priced appropriately. Findings indicate that corporate disclosures of quantitative greenhouse gas (GHG) emissions and, to a lesser extent, carbon performance are value relevant. We use hand‐collected information on quantitative GHG emissions for 433 European companies and build portfolios based on GHG disclosure and performance. We regress portfolios on a standard four factor model extended for industry effects over the years 2005 to 2009. Results show that investors achieved abnormal risk‐adjusted returns of up to 13.05% annually by exploiting inefficiently priced positive effects of (complete) GHG emissions disclosure and good corporate climate change performance in terms of GHG efficiency. Results imply that, firstly, information costs involved in carbon disclosure and management do not present a burden on corporate financial resources. Secondly, investors should not neglect carbon disclosure and performance when making investment decisions. Thirdly, during the period analysed, financial markets were inefficient in pricing publicly available information on carbon disclosure and performance. Mandatory and standardised information on carbon performance would consequently not only increase market efficiency but result in better allocation of capital within the real economy. 相似文献

We study the pricing and hedging of derivative securities with uncertainty about the volatility of the underlying asset. Rather than taking all models from a prespecified class equally seriously, we penalise less plausible ones based on their “distance” to a reference local volatility model. In the limit for small uncertainty aversion, this leads to explicit formulas for prices and hedging strategies in terms of the security’s cash gamma. 相似文献

When potential income tax reforms are debated, the suspected impact on entrepreneurship is often used as an argument in favour of or against a certain policy. Quantitative ex‐ante evaluations of the effect of certain tax reform options on entrepreneurship are very rare, however. This paper estimates the ex‐ante effects of the German tax reform 2000 and of two hypothetical flat‐rate tax scenarios on entries into and exits out of self‐employment based on a structural microsimulation model with econometrically estimated transition rates under risk. The simulation results indicate that flatter tax systems do not encourage people to choose self‐employment, but rather discourage them from doing so. This is explained by the reduction of entrepreneurs' income risk through progressive taxation. 相似文献

Short horizons, time inconsistency, and optimal social security 总被引:1,自引:0,他引:1
We study the optimal provision of social security in a dynamically efficient economy using a continuous-time overlapping-generations
model in which consumers have short planning horizons. The short-horizon mechanism leads to dynamic optimization that is time-inconsistent
over the life cycle. Our calibrated general-equilibrium results are generally supportive of social security for a wide array
of social welfare functions. Thus, the basic life-cycle model can be augmented with only this slight twist in order to rationalize
a social security program with the current U.S. tax rate. 相似文献

Summary. The study of evolutionary dynamics was so far mainly restricted to finite strategy spaces. In this paper we show that this
unsatisfying restriction is unnecessary. We specify a simple condition under which the continuous time replicator dynamics
are well defined for the case of infinite strategy spaces. Furthermore, we provide new conditions for the stability of rest
points and show that even strict equilibria may be unstable. Finally, we apply this general theory to a number of applications
like the Nash demand game, the War of Attrition, linear-quadratic games, the harvest preemption game, and games with mixed
strategies.
