The role of social proximity in professional CEO appointments: Evidence from caste/religion‐based hiring of CEOs in India

Research Summary: The role of homophily in CEO appointments at the largest corporations is an important subject in corporate governance. This subject is particularly important in a country like India where a multitude of religions, castes, and communities form its social fabric. We test for the role of homophily in professional CEO appointments in India by empirically examining the preference for same caste/religion CEOs by the largest firms. Using a unique dataset, assembled by detailed identification of castes/religions from family names and counterfactuals obtained through the Coarsened Exact Matching technique, we find that caste/religion plays a crucial role in CEO selection as a source of information (positive discrimination). The evidence is not consistent with its use to pursue taste‐based preferences (negative discrimination). Managerial Summary: We test for the role of homophily in the appointments of CEOs in India by empirically examining the preference for same caste/religion CEOs by the largest firms. We find that caste/religion plays an important role in CEO selection, i.e., as a form of information or “positive discrimination.” The evidence is not consistent with its use to pursue taste‐based preferences or “negative discrimination.”     

Debt, debt structure and corporate performance after unsuccessful takeovers: evidence from targets that remain independent

Significant increases in the level of target leverage have been previously documented following unsuccessful takeover attempts. This increased leverage may signal managerial commitment to improved performance, suggesting that corporate performance and leverage should be positively related. If, however, the increased leverage leads to further managerial entrenchment, then corporate performance and leverage should be negatively related. In this paper, we reexamine both motivations for the observed increase in leverage. Furthermore, we argue that changes in the composition of debt are also important, besides changes in the level of leverage. In particular, bank debt has frequently been assigned a proactive, beneficial monitoring role in the literature. Besides confirming the increase in the level of leverage, we also document increases in bank debt surrounding cancelled takeovers. As a result, we find a more complex relation between corporate performance and debt use: Overall, the relation between corporate performance and leverage is negative, as predicted by a dominant entrenchment effect. However, increases in bank debt reduce the adverse effect of the increase in the level of leverage.     

Can Diversification Create Value? Evidence from the Electric Utility Industry

Despite SEC and state-level resistance, and contrary to the trend pursued by other firms, many electric utilities have diversified into non-electric and unregulated businesses. Moreover, this failure to focus has been rewarded with higher firm values, again contrary to the discounts documented in the literature for other diversifying firms. Prior literature has questioned whether these premiums (or discounts) can be attributed to diversification per se. Rather, these premiums could arise from the characteristics of the diversifying firms, which have then endogenously chosen to diversify. In a new approach, where regulation can make the diversification decision largely exogenous, we examine the investment policies of the comparable electric-segments in the diversifying and non-diversifying utilities. We find that single-segment electric utilities over-invest compared to diversifying utilities, which explains their diversification premiums and implies that diversification can create value by opening up new investment opportunities.     

Comparing the resource‐based and market‐based views of the firm: empirical evidence from Czech privatization

The recent privatization of state‐owned enterprises in the Czech Republic forms a natural experiment to test and compare the predictive ability of the resource‐based view (RBV) against the market‐based view (MBV) under conditions of great change. It has been recognized in the literature that, under normal stable circumstances, a firm's internal resources and its external market power are fundamentally intertwined. Consequently, it is difficult to identify the relative roles of these two theories in explaining expected firm performance and firm value. However, when market conditions are in a state of flux, as in the case of the Czech Republic in 1992, we expect the firm's resources to be the primary determinants of firm value. In order to test this notion, an RBV model was developed, based on a set of firm features reflecting the rare and valuable ability to compete in the emerging capitalistic economy (as opposed to the currently prevailing bureaucratically planned economy). A contrasting MBV model was also developed, highlighting the role of market power in this regard. These models were assessed in a cross‐sectional sample of 988 Czech firms undergoing privatization. The empirical findings show that the RBV‐driven variables are remarkably better at explaining share values of Czech firms in the period of privatization than MBV‐driven variables. These results underscore the role of firm resources as a primary determinant of firm value in rapidly changing environments. Copyright © 2003 John Wiley & Sons, Ltd.     

Determinants of Foreign Ownership in Newly Privatized Companies in Transition Economies

We investigate determinants of foreign ownership in newly privatized firms. We analyze data on privatized Czech firms to address two related general questions. First, what characteristics distinguish transition firms that attract a foreign investor? Second, how do firm‐specific characteristics influence the size of the foreign equity stake? Our results suggest that foreign investors i) seek safe, profitable firms in which they can exert unchallenged influence on corporate governance and then ii) structure their equity stakes to mitigate agency costs and political risk.     

RISK AND RETURN ON NEWLY LISTED STOCKS: THE POST-LISTING EXPERIENCE

Researchers consistently find that newly listed stocks underperform in the post-listing period. It has been suggested that this anomalous finding may, in part, be explained away if the risk during this period is lower than at other times. Evidence is presented here that the riskiness of newly listed stocks undergoes a seasoning process. Instead of lower risk, riskiness is found to be greater immediately after listing than in later periods. This suggests that the post-listing anomaly is actually worse than has been previously recognized.     

Cost-consequence analysis of two different active flowable hemostatic matrices in spine surgery patients

Objectives: A recently published retrospective analysis comparing two different active flowable hemostatic matrices (FLOSEAL and SURGIFLO Kit with Thrombin) showed significantly increased resource use and complications (surgery time, risk of blood product transfusion, and amount of matrix used) with SURGIFLO use compared to FLOSEAL in major spine surgery, and also significantly increased surgical time with SURGIFLO use in severe spine surgery. This analysis was developed as a follow-up to this prior analysis, to evaluate the cost-consequence of using FLOSEAL vs SURGIFLO in major and severe spine surgery.

Methods: A cost consequence model was constructed from a US hospital provider perspective. Model parameters combined clinical inputs from the published retrospective analysis with supplemental analyses on annual spine surgery volume using the 2012 National Inpatient Sample (NIS) database. Cost of hemostatic matrices, blood product transfusion, and operating room time were identified from published literature. Various one-way and probabilistic sensitivity analyses were performed.

Results: The base case for a medium volume hospital showed that, compared to SURGIFLO, patients receiving FLOSEAL required three fewer blood product transfusions and saved 27?h of OR time, resulting in annual savings of $151 per major and $574 per severe spine surgery. Additional scenarios for high and low volume hospitals supported cost savings in the base case. Probabilistic sensitivity analysis revealed FLOSEAL was cost-saving in 76% of simulations in major spine and 97% of iterations in severe spine surgery.

Conclusions: This economic analysis indicates that use of FLOSEAL instead of SURGIFLO hemostatic matrices to induce hemostasis in both major and severe spine surgery could potentially lead to sizable cost savings in US hospitals, regardless of spinal surgery case-mix.     

Volatility of stock prices and market efficiency

Recently, historical price series along with the dividend series have been used to severely question the Efficient Markets Hypothesis. The literature suggests that the stock prices vary too much to be explained by subsequent changes in dividends. It is argued in this paper that these results require the assumption of stationarity of the price process and that this assumption is not compatible with the random walk model of Efficient Markets. A non-stationary dividend process, which is compatible with the random walk model of Efficient Markets, results in a reversal of earlier results. The new results are shown to be consistent with the empirical findings. Simulations are run to verify the results.
