dynamic jump intensities and risk premiums evidence from s p500 returns and options we build a new class of discrete time models that are relatively easy to estimate using returns and or options the distribution of returns is driven by two factors dynamic volatility and dynamic jump intensity each factor has its own risk premium the models significantly outperform standard models without jumps when estimated on s p500 returns we find very strong support for time varying jump intensities compared to the risk premium on dynamic volatility the risk premium on the dynamic jump intensity has a much larger impact on option prices we confirm these findings using joint estimation on returns and large option samples

effects of announcements of reorganization outcome less is known about whether the market perceives the final resolution of post reorganization filing to be idiosyncratic or to carry endemic implications for the corresponding industries this study observes the presence of intra industry information transfers the magnitude and direction of the reactions in response to three separate resolution outcome differs in a systematic way across industry portfolios specifically portfolio rivals that are affected by competitive realignments in the industry experience stock price reactions in the opposite manner to those of the distressed firms thus suggesting dominant competitive effects in addition this study reveals that the discriminatory power and forecast performance of three hybrid neuro fuzzy models are stable and unimpaired across time and are generally superior in classifying rival cumulative prediction error rcpe candidates

exact and heuristic solutions of the global supply chain problem with transfer pricing we examine the example of a multinational corporation that attempts to maximize its global after tax profits by determining the flow of goods the transfer prices and the transportation cost allocation between each of its subsidiaries vidal and goetschalckx vidal c j goetschalckx m 2001 a global supply chain model with transfer pricing and transportation cost allocation european journal of operational research 129 1 134 158 proposed a bilinear model of this problem and solved it by an alternate heuristic we propose a reformulation of this model reducing the number of bilinear terms and accelerating considerably the exact solution we also present three other solution methods an implementation of variable neighborhood search vns designed for any bilinear model an implementation of vns specifically designed for the problem considered here and an exact method based on a branch and cut algorithm the solution methods are tested on artificial instances these results show that our implementation of vns outperforms the two other heuristics the exact method found the optimal solution of all small instances and of 26 of medium instances

conducting event studies with thinly traded stocks abstract procedures for measuring abnormal performance around events when securities do not trade daily are examined a rank test patterned after the statistic proposed by corrado corrado c j 1989 a nonparametne test for abnormal security price performance in event studies journal of financial economics 23 385 395 is derived the empirical frequency distributions of the rank test statistic and a conventional test statistic are assessed under different rules for handling missing stock returns the results suggest that the traditional procedures are reasonably well specified for thickly and moderately traded stocks but misspecified for thinly traded stocks the rank test however performs well for all trading frequencies and trade to trade returns are the best way to handle missing returns

interim news and the role of proxy voting advice this paper examines the information content and consequences of third party voting advice that arrives as news at an interim stage in corporate proxy contests we first document significant stock returns around announcements of proxy vote recommendations we then develop a multiequation empirical procedure for disentangling the price impact of prediction effects changes in contest outcome probabilities from the price impact of certification effects changes in outcome contingent valuations both effects are present in the data voting advice is both predictive about contest outcomes and informative about the ability of dissidents to add value consequently proxy advice plays a dual informational role

uk directors trading the impact of dealings in smaller firms this paper reasesses the u k results of significant abnormal returns from directors trading for a new sample of directors trades 1984 86 and finds that abnormal returns tend to be concentrated in smaller firms when an appropriate benchmark portfolio is used it is found that the significance of the abnormal returns is substantially reduced with the implication that directors trading does not yield particularly high profits to either the directors themselves or to an outside investor mimicking those trades coauthors are john matatko ian tonks and richard purkis copyright 1994 by royal economic society

a note on information seasonality and the disappearance of the weekend effect in the uk stock market the weekend effect in uk stock prices has disappeared in the 1990s beneath the surface however there remain systematic day of the week effects only visible when returns are partitioned by the direction of the market a systematic pattern of market wide news arrivals into the uk stock market is discovered and found to provide an explanation for these day of the week effects

performance changes around bank mergers revenue enhancements versus cost reductions this paper examines operating performance around commercial bank mergers we find that industry adjusted operating performance of merged banks increases significantly after the merger large bank mergers produce greater performance gains than small bank mergers activity focusing mergers produce greater performance gains than activity diversifying mergers geographically focusing mergers produce greater performance gains than geographically diversifying mergers and performance gains are larger after the implementation of nationwide banking in 1997 further we find improved performance is the result of both revenue enhancements and cost reduction activities however revenue enhancements are most significant in those mergers that also experience reduced costs

creative destruction and firm specific performance heterogeneity traditional u s industries with higher firm specific stock return and fundamentals performance heterogeneity use information technology it more intensively and post faster productivity growth in the late 20 th century we argue that this mechanically reflects a wave of schumpeter s 1912 creative destruction disrupting a wide swath of industries with successful it adopters unpredictably undermining established firms this validates endogenous growth theory models of creative destruction e g aghion and howitt 1992 and suggests intensified creative destruction as explaining findings associating greater firm specific performance variation with higher per capita gdps economy growth rates accounting standards financial system development and property right protection

corporate governance through the proxy contest evidence and implications the current literature concerning proxy contests provides little evidence that shareholders suffer materially from sub par performance prior to a contest furthermore no study has thoroughly examined the long term performance of targeted firms subsequent to a proxy contest using a sample of ninety seven election contests during the period 1968 87 the authors find negative abnormal returns and deteriorating operating performance prior to the announcement of a contest following the contest negative abnormal returns are observed these negative returns are driven by cases in which dissident shareholders successfully acquire board seats the results for accounting based operating performance measures confirm these findings copyright 1993 by university of chicago press

competitiveness through management of diversity effects on stock price valuation this study s premise is that firms that can lower their costs and enhance their differentiation through the effective management of their human resources have a competitive advantage using data fr

issuing costs to existing shareholders in competitive and negotiated underwritten public utility equity offerings abstract this paper presents the results of an empirical investigation of whether there is any difference in the cost incurred by public utilities if they issue new equity through a negotiated or competitive underwriting we conclude that the expected cost of a competitive offer is less than the expected cost of a negotiated offer but that the variance of the cost is substantially greater with a competitive offer these results are interesting because most public utilities use negotiated underwriting unless forced by regulation to use competitive offers this paper is also an addition to the growing agency theory literature

share price and mortality an empirical evaluation of newly listed nasdaq stocks abstract we examine a sample of 5896 stocks listed on nasdaq between 1974 and 1988 to see whether the price per share has significant statistical power in forecasting subsequent returns and attrition rates consistent with anecdotal evidence we document a higher mortality rate for lower priced stocks than for higher priced issues surprisingly mortality is not related to market capitalization our results also hold for subsamples partitioned by industry and issue year on average investors are not adequately compensated for this additional mortality risk earning lower risk adjusted rates of return on portfolios of lower priced shares than on portfolios of higher priced shares

redesign of global supply chains with integration of transfer pricing mathematical modeling and managerial insights abstract unlike the supply chain sc design problem which deals with the configuration of a new sc the redesign problem assumes that a sc already exists and focuses on its reconfiguration in order to take profit of the changing logistics financial and fiscal advantages offered by each country first this requires considering specific decisions and cost factors such as those associated with facility closing and capacity relocation these aspects are often ignored by sc design models second to better capitalize on the tax advantages in each country the redesign of sc requires the consideration of taxation rates and mainly transfer pricing indeed companies can use transfer pricing to shift profits to lower tax countries which may impact on the sc redesign decisions e g on the relocation of operations and manufacturing facilities this paper contributes to the literature by 1 developing a large scale optimization model that is specific to the problem of sc redesign while addressing decisions costs and complexity factors that are often ignored by the model based sc design literature 2 integrating transfer pricing in the model by using two methods one of them is the profit split method that is dictated by the oecd transfer pricing guidelines 1995 2010 which could be considered as a novelty in large scale sc optimization models and 3 using the model to derive a series of insights that may be helpful for companies and governments most of these insights are difficult to obtain without the support of models like the one developed here

riskiness endogenous productivity dispersion and business cycles abstract in the data cross sectional productivity dispersion is countercyclical at both the plant level and the firm level see e g bloom 2009 i incorporate a firm s choice of risk level into a model of firm dynamics with real business cycle features to explain this empirical finding both qualitatively and quantitatively in the model in every period each firm chooses the investment amount and the risk level associated with a production project every period all projects available to each firm have the same expected flow return determined by the aggregate and idiosyncratic shocks to the firm s productivity and differ from one another only in their risk the endogenous option of exiting the market and the limited funding for new investment jointly play an important role in motivating firms risk taking behavior the model predicts that in each period relatively small firms are more likely to take risk and hence exhibit a higher exit rate and that the cross sectional productivity dispersion measured as the standard deviation of the realized individual component of productivity is larger in recessions

productivity and employment dynamics of us manufacturing plants abstract this study estimates the plant level dynamics of productivity and employment in the united states we use the annual survey of manufactures from the us census bureau for the period 1972 1997 applying the system generalized method of moments estimation developed by blundell and bond 1998 we find that productivity and employment processes are both strongly persistent

stock market anomalies abstract this paper reports evidence documenting the presence of a number of irregularities in stock price behaviour of firms on the london stock exchange the size effect is not only not the sole anomaly but is not even the most dominant one specifically investment strategies based on dividend yield pe ratios and share prices appear as profitable if not more as a strategy concentrating on firm size although there is a large degree of interdependency between all four effects it is still apparent that the dividend yield and pe ratios subsume the size and share price effects

proxy contests and the governance of publicly held corporations abstract analysis of 60 proxy contests for seats on the boards of exchange listed firms during 1978 1985 shows that three years after the contest less than one fifth of the sample firms remain independent publicly held corporations run by the same management team proxy contests are typically followed by managerial resignations even when dissidents fail to obtain a majority of board seats and are often followed by sale or liquidation of the firm the average stockholder wealth gains associated with proxy contests are largely attributable to gains by companies in which dissident activity leads to sale or liquidation

the relationship between firm growth size and age estimates for 100 manufacturing industries this study uses a sample of all firms operating in 100 manufacturing industries to examine some aspects of firm dynamics it finds that firm growth the variability of firm growth and the probability that a firm will fail decrease with firm age it also finds that firm growth decreases at a diminishing rate with firm size even after controlling for the exit of slow growing firms from the sample gibrat s law therefore fails although the severity of the failure decreases with firm size copyright 1987 by blackwell publishing ltd

entry exit and investment specific technical change using european data this paper finds that i industry entry and exit rates are positively related to industry rates of investment specific technical change istc and ii the sensitivity of industry entry and exit rates to cross country differences in entry costs depends on industry rates of istc the paper con structs a general equilibrium model in which the rate of istc varies across industries and new investment specific technologies can be introduced by entrants or by incumbents in the calibrated model equilibrium behavior is consistent with stylized facts i and ii provided the cost of technology adop tion is increasing in the rate of istc jel g31 li 1 031 033 entry and exit rates differ significantly across industries over the period 1963 1982 timothy dunne mark j roberts and larry samuelson 1988 find that five year entry rates in us manu facturing data range from 21 percent in tobacco to 60 percent in scientific instruments high entry industries are high exit industries suggesting that entry and exit are largely due to the same industry specific factors at the same time little is known about what these factors might be this paper finds a strong positive link between industry entry and exit rates and the pace of technical progress in the capital goods that the industry uses the rate of investment specific technical change istc a significant fraction of entry and exit thus represents the introduction and replacement of capital embodied technologies istc is also positively related to the proportion of enterprises in each industry that displays large investment outlays in a given year that investment often occurs in spikes has been known since at least mark doms and dunne 1998 and the results link this pattern to the replacement of new capital embodied technologies by incumbents furthermore the decision of whether or when to exit appears sensitive to policy in countries in which the cost of entry is high rates of entry and exit are disproportionately suppressed in industries with high rates of istc to analyze these findings the paper develops a general equilibrium model in which chang ing the vintage of capital used by a particular enterprise is costly in the model this vintage is termed a technology and an enterprise is a technology manager pair the manager accumu lates expertise with a given technology over time and at any date may choose to upgrade to a newer technology at the expense of accumulated expertise as in boyan jovanovic and yaw

the winner s curse legal liability and the long run price performance of initial public offerings in finland abstract rationing data for initial public offerings ipos in the finnish market make possible a test of rock s 1986 winner s curse hypothesis the evidence from 80 ipos issued between 1984 and 1989 confirms the presence of the winner s curse average returns adjusted for the bias in allocation are lower than average unadjusted returns but the initial returns of these ipos appear unrelated to lawsuit avoidance as the sample firms seem unlikely to incur legal liabilities in the long run consistent with the evidence in the united states the ipo firms substantially underperform the helsinki stock exchange value weighted index

communication costs information acquisition and voting decisions in proxy contests this article synthesizes some recent progress in the theories of corporate control and political lobbying to model the proxy campaign as a political campaign the model yields a number of testable implications only some of which have been examined in the literature for example if the loss from voting for a bad dissident exceeds the gain from voting for a good dissident the model predicts that as communication costs fall the number of proxy fights increases announcement day returns decrease and the fraction of dissident wins first increases and then decreases article published by oxford university press on behalf of the society for financial studies in its journal the review of financial studies

the timing of option repricing we investigate whether executive stock option repricings are systematically timed to coincide with favorable movements in the company s stock price for a sample of 236 repricing events we observe sharp increases in stock price in the 20 day period following the repricing date in addition repricing dates tend to either precede the release of good news or follow the release of bad news in the quarterly earnings announcements since information about stock option repricing is not generally released to the public around the repricing date these findings suggest that ceos opportunistically manage the timing of the option repricing date

fair transfer price and inventory holding policies in two enterprise supply chains abstract a key issue in supply chain optimisation involving multiple enterprises is the determination of policies that optimise the performance of the supply chain as a whole while ensuring adequate rewards for each participant in this paper we present a mathematical programming formulation for fair optimised profit distribution between echelons in a general multi enterprise supply chain the proposed formulation is based on an approach applying the nash bargaining solution for finding optimal multi partner profit levels subject to given minimum echelon profit requirements the overall problem is first formulated as a mixed integer non linear programming minlp model a spatial and binary variable branch and bound algorithm is then applied to the above problem based on exact and approximate linearisations of the bilinear terms involved in the model while at each node of the search tree a mixed integer linear programming milp problem is solved the solution comprises inter firm transfer prices production and inventory levels flows of products between echelons and sales profiles the applicability of the proposed approach is demonstrated by a number of illustrative examples based on industrial processes

a global supply chain model with transfer pricing and transportation cost allocation abstract we present a model for the optimization of a global supply that maximizes the after tax profits of a multinational corporation and that includes transfer prices and the allocation of transportation costs as explicit decision variables the resulting mathematical formulation is a non convex optimization problem with a linear objective function a set of linear constraints and a set of bilinear constraints we develop a heuristic solution algorithm that applies successive linear programming based on the reformulation and the relaxation of the original problem our computational experiments investigate the impact of using different starting points the algorithm produces feasible solutions with very small gaps between the solutions and their upper bound ub

formation of a strategic manufacturing and distribution network with transfer prices abstract we propose a profit maximization model for the decision support system of a firm that wishes to establish or rationalize a multinational manufacturing and distribution network to produce and deliver finished goods from sources to consumers the model simultaneously evaluates all traditional location factors in a manufacturing and distribution network design problem and sets intra firm transfer prices that take account of tax and exchange rate differentials between countries utilizing the generalized benders decomposition approach we exploit the partition between the product flow and the cash allocation i e the pricing and revenue assignment decisions in the supply chain to find near optimal model solutions our proposed profit maximizing strategic planning model produces intuitive results we offer computational experiments to illustrate the potential valuable guidance the model can provide to a firm s supply chain design strategic planning process

misspecification of capital asset pricing this study documents empirical anomalies which suggest that either the simple one period capital asset pricing model capm is misspecified or that capital markets are inefficient in particular portfolios based on firm size or earnings price e p ratios experience average returns systematically different from those predicted by the capm furthermore the abnormal returns persist for at least two years this persistence reduces the likelihood that these results are being generated by a market inefficiency rather the evidence seems to indicate that the equilibrium pricing model is misspecified however the data also reveals that an e p effect does not emerge after returns are controlled for the firm size effect the firm size effect largely subsumes the e p effect thus while the e p anomaly and value anomaly exist when each variable is considered separately the two anomalies seem to be related to the same set of missing factors and these factors appear to be more closely associated with firm size than e p ratios

an operational profit sharing and transfer pricing model for network manufacturing companies abstract new age companies are forging partnerships with other firms to market products that have been assembled through manufacturing activities distributed at different locations these locations belong to more than one company and the product passes through these different sites during its manufacturing stages this manufacturing collaboration is known as network manufacturing according to the network philosophy companies form alliances to manufacture a product and share in its operating profits this paper proposes a framework and methodology for profit sharing and transfer pricing between network companies we propose a paradigm that enables maximization of operating profits by the manufacturing network in its larger supply chain suggesting a departure from the model that maximizes profits for the individual company within the sphere of its own supply chain

decentralization and transfer pricing under oligopoly this paper presents a simple model of a partially decentralized multinational firm mnf in competition with a rival firm it is shown that transfer pricing can be used as a rent shifting device by the mnf to compete with the rival this arises because the mnf headquarters uses the transfer price to manage different subsidiaries the specific value of the transfer price chosen by the mnf depends on whether the rival firm produces the intermediate good the final good or both and whether the rival is integrated or not in particular both decentralization and competition with a fully integrated rival result in lower transfer prices

measuring abnormal performance do stocks overreact abstract a highly controversial issue in financial economies is whether stocks overreact in this paper we find an economically important overreaction effect even after adjusting for size and beta in portfolios formed on the basis of prior five year returns extreme prior losers outperform extreme prior winners by 5 10 per year during the subsequent five years although we find a pronounced january seasonal our evidence suggests that the overreaction effect is distinct from tax loss selling effects interestingly the overreaction effect is substantially stronger for smaller firms than for larger firms returns consistent with the overeaction hypothesis are also observed for short windows around quarterly earnings announcements

gray market trade with product information service in global supply chains abstract this paper investigates the economic effects of a product information service when potential consumers who are segmented by their taste exist in gray markets specifically we construct an economic model that considers a multinational firm mnf who expands business to a country and chooses whether to provide information service regarding product characteristics if receiving the information consumers in a specific segment whose taste suits the characteristics have positive utility from consuming the product while those in other segments have no utility by contrast consumers in all segments have positive expected utility before consuming the product without information with these settings we demonstrate that there arises the equilibrium that the mnf provides no information service when gray market trade i e parallel trade is allowed in the country leading to lower consumer welfare than when it is prohibited a primary finding in the equilibrium is that such a situation arises especially when potential consumers are less segmented in this situation the regulator in the country should ban the parallel imports so as to enhance consumer welfare the result is counterintuitive and notable because one might intuitively infer that gray market trade is less desirable when customers are more minutely segmented and the product information service is thus more specific and necessary

accounting information and corporate governance market and analyst reactions to earnings of firms engaged in proxy contests abstract this paper studies market and analyst reactions to earnings i during a proxy contest for board seats and ii after a proxy contest induced management change despite indications of earnings management during the proxy contest market and analyst reactions are more pronounced than in prior periods and earnings surprises explain more of the cross sectional variation in these reactions market and analyst reactions to earnings released after a successful proxy contest are less pronounced than in prior periods and earnings surprises explain less of the variation in these reactions perhaps due to new managements tendency to take an earnings bath

transfer pricing mechanisms an experimental investigation abstract this study evaluates in a laboratory setting the performance of the ronen and mckinney 1970 and the ronen 1992 transfer pricing schemes both mechanisms possess in theory the property of inducing efficient production and truth telling while decision making autonomy is maintained the ronen mckinney scheme however allows for multiple nash equilibria and if the divisions managers coordinate their messages they are expected to exploit the mechanism at the expense of the overall profitability of the firm the ronen 1992 scheme was designed to prevent this towards this end a penalty factor was incorporated into the original ronen mckinney scheme to make truth telling and optimal production a unique equilibrium the basic results are that under the ronen mckinney scheme and with coordination of messages being allowed subjects collude and earn significantly higher profits than amounts implied by the overall optimal solution without the penalty factor subjects seemed not to converge towards the efficient level of transacting at the end of the experiment it is not clear whether with additional trials such conversion would have occurred the inclusion of the penalty factor however eliminated the collusive behaviour in fact most of the pairs implementing the ronen mechanism reached the efficiency predicted by the theory whether or not coordination of messages was allowed

the stability of uk risk measures and the problem of thin trading this paper examines the problems of estimating risk measures and their stability in thin markets it shows analytically that conventional approaches used in previous studies can lead to serious overestimates of the stability of risk measures when shares are subject to thin trading it then demonstrates using uk data that this is in fact a serious practical problem and that the resultant biases are of precisely the form predicted finally the paper presents reliable evidence on the stability of uk risk measures by using an estimation method designed to avoid thin trading bias using this approach risk measures are found to be as stable in the uk as they are in the usa this paper examines the stability of risk measures in the uk the focus is on providing reliable evidence in a market where many of the shares suffer from thin trading this is important because thin trading can seriously distort stability measures leading to incorrect conclusions indeed this is a problem which has almost certainly afflicted many previous studies of stability the paper makes four main contributions first it shows analytically that thin trading can lead to serious overstatements about stability second it uses uk data to illustrate that this is in fact a serious practical problem and that the biases are of precisely the form predicted this is important for anyone who wishes to interpret previous claims on beta stability in thin markets third the paper presents reliable evidence on the stability of uk betas by using an estimation method designed to avoid thin trading bias besides avoiding bias our

econometric properties of alternative security return methods in recent years security price research has experienced a proliferation of research designs as a result there is a lack of interstudy comparability which is aggravated by the absence of a formal analysis of the properties of the alternative designs under various conditions the purpose here is to examine one important aspect of research design the choice of the security return measure in a simple but well defined setting of limited parameter uncertainty the analysis leads to the following results 1 with respect to raw returns versus residual returns it explicitly offers three potential rationales for residual returns as such the analysis provides a formal statement of the reasons for residual analyses to supplement the intuitive but less precise statements in the early literature 2 with respect to residual return versus difference in returns methods the analysis indicates the conditions under which a the residual approach dominates the difference in returns approach as judged by the statistical criteria examined b the converse holds and c the two methods possess the same econometric properties 3 the relative properties described in 2 are derived for a general model of nonzero covariation among returns and for two important special cases the zero beta model and the industry effects model

on corporate governance a study of proxy contests abstract this paper examines a sample of firms experiencing proxy contests for seats on their board of directors dissident shareholders usually fail to obtain a majority of board seats nevertheless they capture some seats via mechanisms such as cumulative voting in over half of the sample contests regardless of proxy contest outcome positive and statistically significant share price performance is associated with the contest that finding is predicted by the standard economic analysis of proxy contests in which the challenges benefit shareholders by improving corporate performance the finding runs counter to the claim of berle 1962 that the economists view of proxy contests is a wholly imaginary picture a portion of the positive share price changes taking place in the early stages of some proxy contests is not permanent however and as suggested by manne 1962 is at least partially attributable to temporary increases in the market value of the vote attached to corporate shares

cross sectional association between abnormal returns and firm specific variables abstract abnormal returns market model prediction errors are the subject of many event studies in accounting and finance literature conditional on the event of interest researchers have recently used cross sectional regressions to examine relations between abnormal returns and firm specific variables this paper demostrates that non constant variences and covariances in market model residuals across firms introduced bias in the estimated slope coefficients of the independent variables i e the expected signs of the estimated slope coefficients can be predicted a priori a method is develope to removed the bias in the estimated slope coefficiets and is found to be effective this method explicitly takes the dependence among abnormal returns across firms into account methods that assume abnormal returns across firms to be independent do not control for such bias

intrafirm trade arm s length transfer pricing rule and coordination failure abstract this paper demonstrates that uniform imposition of the arm s length principle on transfer pricing leads to coordination failure among countries in terms of economic welfare if the countries trade products in the form of intrafirm transactions by multinational firms mnfs to highlight this implication we first show that imposition of the arm s length principle on an mnf induces it to transfer a product among subordinate divisions at marginal cost i e the competitive price which is consistent with the purpose of the principle nonetheless if regulators in each country impose the principle on mnfs all of the following economic welfare measures decrease compared with the situation where the principle is not imposed 1 consumer welfare in each of the trading countries 2 profit of each mnf and thus 3 total world economic welfare this result indicates that it is possible that enforcement of the principle has no positive effect at all in the world because economic welfare of all economic agents deteriorates when the principle is imposed a numerical analysis demonstrates that this possibility arises in a broad range of circumstances even including the situation where a giant economic world power and a small underdeveloped country mutually trade products in these circumstances an agreement among trading countries that no country imposes the arm s length principle may encourage pareto improvement of the world economy

changes in organizational structure and shareholder wealth the case of limited partnerships this paper analyzes the consequence for shareholders of a change in organizational form the conversion of a corporation or the spin off of a unit into a limited partnership theory suggests that prior to the tax reform act of 1986 the tax benefits of conversion to a limited partnership and the creation of a new entity separate from the parent corporation should have a positive effect on shareholder wealth on the other hand the increase in agency costs of such an organizational change should decrease the wealth of shareholders empirical results lend support to hypotheses that predict an increase in stock price at the announcement of the conversion but cannot identify the source of the gain

the social construction of market value institutionalization and learning perspectives on stock market reactions this study advances a social constructionist view of financial market behavior the paper suggests that the market s reaction to particular corporate practices such as stock repurchase plans are not as financial economists contend simply a function of the inherent efficiency of such practices rather stock market reactions are also influenced by the prevailing institutional logic and the degree of institutionalization of the practice the theory first predicts that the emergence of the agency perspective on corporate governance in the mid 1980s represented a powerful new institutional logic that would lead the market to reverse its prior aggregate reaction to stock repurchase plans in the united states the paper then considers the potential for institutional decoupling of repurchase plans and develops competing hypotheses about how the market value of these policies might have changed as more firms formally adopted but did not implement the plans over time in contrast to a financial economic pers

joint inventory and cash management for multidivisional supply chains this paper develops a centralized supply chain model that integrates material flows with cash flows the supply chain is owned by a single firm with two divisions the downstream division headquarters facing random customer demand replenishes materials from the upstream division the firm installs a financial services platform that pools the divisions cash into a master account managed by the headquarters in each period cash is received from customers and paid to the outside vendor after materials are delivered the headquarters determines how much cash to retain for inventory replenishment the objective is to determine an optimal joint inventory replenishment and cash retention policy for the entire supply chain we prove that the optimal policy has a surprisingly simple structure both divisions implement a base stock policy for inventory replenishment the headquarters monitors the corporate working capital and implements a two threshold policy for cash retention this result is obtained by exte

the outsourcing of r d through acquisitions in the pharmaceutical industry abstract we examine the performance of 160 pharmaceutical acquisitions from 1994 to 2001 and find evidence that on average acquirers realize significant positive returns these returns are positively correlated with prior acquirer access to information about the research and development activities at target firms and a superior negotiating position a unique desperation index is employed to determine the current status of a firm s internal productivity we find that firms experiencing declines in internal productivity or which are more desperate are more likely to engage in an outsourcing type acquisition in an effort to replenish their research pipelines

the impact of environmental management on firm performance environmental management has the potential to play a pivotal role in the financial performance of the firm many individuals suggest that profitability is hurt by the higher production costs of environmental management initiatives while others cite anecdotal evidence of increased profitability a theoretical model is proposed that links strong environmental management to improved perceived future financial performance as measured by stock market performance the linkage to firm performance is tested empirically using financial event methodology and archival data of firm level environmental and financial performance significant positive returns were measured for strong environmental management as indicated by environmental performance awards and significant negative returns were measured for weak environmental management as indicated by environmental crises the implicit financial market valuation of these events also was estimated cross sectional analysis of the environmental award events revealed differences for first time awards and between industries first time award announcements were associated with greater increases in market valuation although smaller increases were observed for firms in environmentally dirty industries possibly indicative of market skepticism this linkage between environmental management and financial performance can be used by both researchers and practitioners as one measure of the benefits experienced by industry leaders and as one criterion against which to measure investment alternatives

the individual investor and the weekend effect it is well known that stock returns on average are negative on mondays yet it is less well known that this finding is substantially the consequence of returns in prior trading sessions when friday s return is negative monday s return is negative nearly 80 percent of the time with a mean return of 0 61 percent when friday s return is positive the subsequent monday s mean return is positive 0 11 percent this relationship is stronger than for any other pair of trading days and is most acute in small and medium size companies the trading behavior of individual investors appears to be at least one factor contributing to this pattern individual investors are more active sellers of stock on mondays particularly following bad news in the market

a theory of financing constraints and firm dynamics there is widespread evidence supporting the conjecture that borrowing constraints have important implications for firm growth and survival in this paper we model a multiperiod borrowing lending relationship with asymmetric information we show that borrowing constraints emerge as a feature of the optimal long term lending contract and that such constraints relax as the value of the borrower s claim to future cash flows increases we also show that the optimal contract has interesting implications for firm dynamics in agreement with the empirical evidence as age and size increase mean and variance of growth decrease and firm survival increases

management buyout proposals and inside information this paper explores stock price behavior surrounding withdrawn buyout proposals to determine whether managers proposal announcements reveal any information which is unrelated to the efficiency gains associated with completed buyouts on average firms whose managers withdraw buyout proposals do not sustain significantly positive stock price effects unless they receive subsequent acquisition bids in addition managers of firms with completed buyouts are no more likely to have access to inside information than managers who withdrew proposals i interpret this evidence as inconsistent with the notion that inside information commonly motivates management buyout proposals management buyouts occur when a group of investors including some incumbent managers buy all of a firm s outstanding common stock with the intent of taking it private critics of management buyouts argue that managers access to inside information allows them to time their proposals to expropriate the wealth of outside shareholders these opponents generally cite anecdotal evidence that favorable inside information motivates management buyout proposals 1 managers themselves suggest that their proposals are motivated at least in part by their information advantage 2 however assistant professor of finance texas a m university this paper is based on my univer

competition imitation and growth with step by step innovation is more intense product market competition and imitation good or bad for growth this question is addressed in the context of an endogenous growth model with step by step innovations in which technological laggards must first catch up with the leading edge technology before battling for technological leadership in the future in contrast to earlier schumpeterian models in which innovations are always made by outsider firms who earn no rents if they fail to innovate and become monopolies if they do innovate here we find first that the usual schumpeterian effect of more intense product market competition pmc is almost always outweighed by the increased incentive for firms to innovate in order to escape competition so that pmc has a positive effect on growth second that a little imitation is almost always growth enhancing as it promotes more frequent neck and neck competition but too much imitation is unambiguously growth reducing the model thus points to complementary roles for competition anti trust policy and patent policy

market reaction to business week inside wall street column a self fulfilling prophecy abstract this study focuses on stocks mentioned in a business week bw column in which over half the stories quote an analyst as a source the results of the study show that stocks with a favorable report in bw earn positive abnormal returns at the time of the distribution of the weekly however this is true only for stocks followed by less than twenty analysts within this group the market response increases as the number of analysts decreases stocks followed by more than twenty analysts do not respond at the time of their mention in bw we further document that trading volume increases at the time of the publication of the story the six month size adjusted post bw performance of the less closely followed stocks with favorable stories is negative and offsets the abnormal return at the time of the bw story we conclude that the evidence is consistent with the self fulfilling prophecy hypothesis i e traders react to bw stories and influence the prices of stocks only to lose in the long run six months the results also show that information obtained from non analyst sources has a greater impact on stock prices than the information from analyst sources indicating that some of analysts information is already reflected in prices through their clients trading the return reversion over six months is observed for bw stories with both analyst as well as non analyst sources

the effect of private antitrust litigation on the stock market valuation of the firm the authors study the implications for shareholder wealth of interfirm antitrust litigation and how the costs of the dispute affect the propensity to settle upon filing defendants experience significant wealth losses that are ten million dollars larger than the wealth gains of plaintiffs financial distress behavioral constraints and follow on suits are sources of wealth leakage and influence settlement behavior since the threat of a monetary transfer has little power to explain either wealth effects or the likelihood of settlement the central concern of defendants may be the potential prohibition of profitable business practices copyright 1995 by american economic association

quality awards and the market value of the firm an empirical investigation this paper empirically investigates the impact of winning a quality award on the market value of firms by estimating the mean abnormal change in the stock prices of a sample of firms on the date when information about winning a quality award was publicly announced we note that the abnormal returns generated by the quality award winning announcements provide a lower bound for the impact of implementing an effective quality award improvement program our results show that the stock market reacts positively to quality award announcements statistically significant mean abnormal returns on the day of the announcements ranged from a low of 0 59 to a high of 0 67 depending on the model used to generate the abnormal returns the reaction was particularly strong for smaller firms mean abnormal returns ranged from low of 1 16 to a high of 1 26 and for firms that won awards from independent organizations such as malcolm baldrige philip crosby etc mean abnormal returns ranged from a low of 1 31 to a h

surprise surprise measuring firm level investment innovations abstract using the ifo investment survey for the german manufacturing sector we construct a forty year panel of firm level investment innovations surprises we document the cross sectional and time series properties of this panel and our main findings are the cross sectional dispersion of investment surprises is countercyclical as is their average within firm time series volatility and both are highly correlated this justifies in part strategies in the literature to use cross sectional moments for the calibration of heteroscedasticity at the same time the cross sectional dispersion of investment is procyclical suggesting a nonsmooth capital adjustment friction at the micro level there is substantial dispersion in within firm volatility a feature consistent with a recent literature on information frictions at the firm level finally the aforementioned second moments of investment innovations are granger caused by recessions but not vice versa rendering simple exogenous uncertainty shocks less plausible as drivers of business cycles

determining intra company transfer pricing for multinational corporations abstract although significant attention has been paid to transfer pricing the pricing of intermediate products sold between different divisions within one company the focus has been limited to tax minimization within regulatory boundaries this paper presents a comprehensive model that aims to determine the optimal transfer price for a multinational corporation mnc to maximize the entire organization s profit the model considers the situation in which intermediate products are sold from the mnc s selling divisions to buying divisions the buying divisions further process these intermediate products to produce final products the final products are then sold in both selling divisions and buying divisions across the mnc s global locations in contrast to the existing literature our innovative model incorporates elements such as international transportation costs holding costs taxes tariffs including the introduction of a second tariff and exchange rates this paper also provides managerial insights about the impact of setting transfer prices in different currencies on the variance of each division s profit given exchange rate uncertainty

volume for winners and losers taxation and other motives for stock trading capital gains taxes create incentives to trade our major finding is that turnover is higher for winners stocks the prices of which have increased than for losers which is not consistent with the tax prediction however the turnover in december and january is evidence of tax motivated trading there is a relatively high turnover for losers in december and for winners in january we conclude that taxes influence turnover but other motives for trading are more important we were unable to find evidence that changing the length of the holding period required to qualify for long term capital gains treatment affected turnover investors responding to the tax incentives in the capital gains laws should produce predictable patterns in the volume of trading in a stock but not necessarily in its price this study uses past price patterns as a proxy to measure the incentives to sell or avoid selling a stock and observes trading volumes to estimate the extent to which investors respond to these incentives past price patterns may influence trading volumes for other non tax related reasons as well these are also considered we find that past prices influence current incentives to trade through both tax and non tax motives winners tend to have higher abnormal volumes than losers this would be expected if non tax related motives were predominant however the influence of tax related motives on trading volume is shown by seasonal variations in the relationship between past price changes and turnover as predicted by tax induced trading theories the volume of losers is higher than normal in december and the volume of winners is higher than normal in january we found no evidence that trading volume was affected by changes in the length of the holding period required to qualify for long term capital gains investors reactions to capital gains taxes are important for several reasons first a comprehensive understanding of investor behavior would include both price and volume understanding the relationship between taxes and volume is a fruitful and convenient method of contributing to this subject the resource allocation consequences of capital gains taxes are controversial in part because

conflict of interest and the credibility of underwriter analyst recommendations brokerage analysts frequently comment on and sometimes recommend companies that their firms have recently taken public we show that stocks that underwriter analysts recommend perform more poorly than buy recommendations by unaffiliated brokers prior to at the time of and subsequent to the recommendation date we conclude that the recommendations by underwriter analysts show significant evidence of bias we show also that the market does not recognize the full extent of this bias the results suggest a potential conflict of interest inherent in the different functions that investment bankers perform

event study methodologies and the size effect abstract this study of 862 press recommendations demonstrates that the size effect can distort longer term performance measures and hence event studies relative to similar sized companies post publication performance is neutral however market adjustments the capm and market model with equally or capitalization weighted indexes all produce biased results event studies are most exposed to such bias when the measurement interval is long event securities differ systematically in size or weighting from the index constituents the size effect is large and or volatile and when capm type methodologies are used these distortions are avoided by explicitly controlling for size

an empirical analysis of the reincorporation decision the literature suggests two competing explanations for reincorporations efforts at managerial entrenchment and attempts to improve contractual efficiency the empirical evidence to date is inconclusive to seek further evidence we examine a large sample of firms that changed their state of incorporation over the period 1980 1992 we find that shareholder wealth is decreased by reincorporations that erect takeover defenses but is increased by reincorporations that establish limits on director liability firms that claim they reincorporate to limit the personal liability of their board members and thereby attract better qualified outside directors do in fact expand the outside representation on their boards whereas firms citing other motives do not

why regulate insider trading evidence from the first great merger wave 1897 1903 we use event time methodology to study legal insider trading associated with mergers circa 1900 for mergers with prospective disclosures similar to today s we find substantial value gains at announcement implying participation by outside shareholders despite the absence of insider constraints furthermore preannouncement stock price runups relative to total value gain are no more than those observed for modern mergers insider regulation apparently has produced little benefit for outsiders with the inside information pricing function and related gains shifting to external information specialists other results suggest market penalties for nondisclosure i e insider trading is less successful in a restricted information environment

empirical evidence on on vertical foreclosure i introduction prior to the 1980s the united states department of justice and the federal trade commission actively challenged vertical mergers on the theory that such mergers foreclosed unintegrated rivals in the downstream market from access to inputs supplied by the merged firm this policy changed when critics of the foreclosure theory claimed that vertically integrated firms have no incentive to transfer products between the upstream and downstream markets at a price other than the market price and therefore vertical mergers have no effect on the price charged to consumers 1 the arguments against attacking vertical mergers were also supported by research that demonstrated that vertical integration can enhance efficiency 2 as a result vertical mergers currently receive very little if any attention from the enforcement agencies recent contributions by ordover saloner and salop 1990 krattenmaker and salop 1986 and salinger 1988 1989 have reopened the debate about the competitive effects of vertical mergers they each use theoretical models to show that vertical foreclosures can raise costs to unintegrated rivals and lead to higher prices for consumers although these models demonstrate that foreclosure can be a profitable strategy that injures competition to date these theories have not been tested empirically if vertical foreclosure rarely occurs or if it occurs only in a narrow set of circumstances changes in current policy on vertical mergers may not be justified a necessary but not sufficient condition for anticompetitive foreclosure is that the vertical merger cause the unintegrated rivals to be less profitable this result from previous theoretical work is tested here on a sample selected from all vertical merger cases challenged by the justice department and the federal trade commission during the period 1963 to 1982 we find no evidence of anticompetitive market foreclosure for the sample of cases challenged by the antitrust agencies one possible explanation for our results is that the tests over the entire sample are significantly affected by a few weak cases brought by the government during a period of aggressive antitrust enforcement we test this by examining variables that have been identified by krattenmaker and salop 1986 and the department of justice merger guidelines as being conducive to foreclosure such as barriers to entry and industry concentration even the cases with high industry concentration and barriers to entry which potentially should exhibit substantial market power provide no evidence of foreclosure while this does not preclude anticompetitive foreclosure as a possibility it does call into question the cases brought by the antitrust agencies during the 1960s and the 1970s until the proponents of the more rigorous economic version of the foreclosure theory provide clearer guidelines about the conditions under which vertical mergers are likely to injure competition continuation of the current policy of not contesting these mergers seems justified ii theory of anticompetitive foreclosure the foreclosure arguments used to challenge vertical mergers during the 1950s and 1960s were easily discredited because no formal theory was used to support them more recent attempts to reconstruct the foreclosure theory have used economic models to demonstrate that vertical foreclosure can reduce competition the key to each of these models is that foreclosure raises the costs to the unintegrated rivals of the merged firm and this under certain conditions raises the price of the final product to the consumer the legal definition of foreclosure focuses on the ability of unintegrated firms to buy from or sell to integrated rivals while the economic definition of anticompetitive foreclosure focuses on whether prices to consumers increase salinger 1988 has provided a model that demonstrates the conditions under which anticompetitive foreclosure will occur

the reputational penalties for environmental violations empirical evidence abstract this paper examines the sizes of the fines damage awards remediation costs and market value losses imposed on companies that violate environmental regulations firms that violate environmental laws suffer statistically significant losses in the market value of firm equity the losses however are of similar magnitudes to the legal penalties imposed and in the cross section the market value loss is related to the size of the legal penalty thus environmental violations are disciplined largely through legal and regulatory penalties not through reputational penalties

impact of bovine spongiform encephalopathy on agribusiness in the united kingdom results of an event study of equity prices this article assesses the impact on agribusinesses of the united kingdom government s announcement of a possible link between bovine spongiform encephalopathy and human health three approaches are employed to derive benchmark models against which abnormal returns are estimated a simple market model scholes williams approach and an autoregressive distributed lag model abnormal returns are estimated for single firms and for subsectors over an eight day event window the autoregressive distributed lag model performs best and indicates significant negative abnormal returns in the beef pet food animal feed and dairy sectors and positive abnormal returns in the other meats sector

the effect of pre emptive right amendments on shareholder wealth abstract pre emptive rights allow existing shareholders to purchase a new offering of shares before the general public this paper investigates the effect on shareholder wealth of removing pre emptive rights from corporate charters two hypotheses are constrasted 1 shareholder wealth maximization suggests that management uses this extra degree of freedom to pick the least cost method for raising new equity hence the amendment increases shareholder wealth 2 management welfare maximization holds that management will use the passage of the amendment to maximize their own welfare sometimes to the detriment of shareholders hence the amendment decreases shareholder wealth the evidence indicates that the amendment decreases shareholder wealth

cross sectoral variation in the volatility of plant level idiosyncratic shocks the volatility of plant level idiosyncratic shocks we estimate the volatility of plant level idiosyncratic shocks in u s manufacturing we measure the variation in revenue total factor productivity not explained by either industry or economy wide factors or by establishments characteristics we find that idiosyncratic shocks are much larger than aggregate shocks accounting for about 80 of the overall uncertainty faced by plants plants in the most volatile sector are subject to about six times as much idiosyncratic uncertainty as plants in the least volatile we provide evidence suggesting that idiosyncratic risk is higher in industries where the extent of creative destruction is likely to be greater

volume and turn of the year behavior abstract this paper studies the trading characteristics of listed companies by size and year end behavior there were no transactions on nearly 25 of the days for the smallest decile even at the turn of year which is an active trading period for small companies as a result of low levels of trading and the regulations governing exchange specialists transaction prices and quotations of small listed companies may require several days to fully reflect equilibrium price changes the data confirm the existence of a year end seasonal pattern in rates of return for small companies and suggest that there may be a seasonal pattern for large companies as well

idiosyncratic shocks and the role of nonconvexities in plant and aggregate investment dynamics we examine a model of lumpy investment wherein establishments face persistent shocks to common and plant specific productivity and nonconvex adjustment costs lead them to pursue generalized s s investment rules we allow persistent heterogeneity in both capital and total factor productivity alongside low level investments exempt from adjustment costs to develop the first model consistent with available evidence on establishment level investment rates reassessing the implications of lumpy investment for aggregate dynamics in this setting we find that they remain substantial when factor supply considerations are ignored but are quantitatively irrelevant in general equilibrium the substantial implications of general equilibrium extend beyond the dynamics of aggregate series while the presence of idiosyncratic shocks makes the time averaged distribution of plant level investment rates largely invariant to market clearing movements in real wages and interest rates we show that the dynamics of plants investments differ sharply in their presence thus model based estimations of capital adjustment costs involving panel data may be quite sensitive to the assumption about equilibrium our analysis also offers new insights about how nonconvex adjustment costs influence investment at the plant when establishments face large and weakly persistent idiosyncratic productivity shocks consistent with existing estimates we find that nonconvex costs do not cause lumpy investments but act to eliminate them

cyclical changes in firm volatility we estimate changes in the volatility of firm level sales earnings and employment growth of us firms our method differs from existing measures for firm level sales and employment volatility in that it not only captures longer run changes in volatility but also measures cyclical changes in firm volatility we detect substantial cyclical variation in firm specific volatility around trend firm specific volatility was low in the early 1990s rose in the mid and late 1990s and was high around 2000 our results are consistent with the hypothesis deduced from models with financial frictions that rising idiosyncratic volatility before 2001 contributed to the coincident rise in the external finance premium and to the 2001 recession endogenous pricing models imply that price adjustment is less frequent and disinflation more costly when firm specific volatility is low consistent with endogenous pricing models we find that the output cost of disinflation was three times larger in the early 1990s than in the early 2000s

transfer pricing and decentralized dynamic lot sizing in multistage multiproduct production processes abstract this paper presents the use of a transfer pricing system to coordinate business units in a wagner whitin type model for a decentralized lot sizing problem in a dynamic multistage multiproduct environment the paper includes two major proofs 1 a transfer pricing system enabling optimal decentralized lot sizing is characterized the transfer pricing system can be interpreted as a generalization of the reciprocal method or step down allocation method in cost location accounting and 2 based on a wagner whitin type theorem and the kakutani fixed point theorem it is shown that such a transfer pricing system exists

competition in multiechelon assembly supply chains in this paper we study competition in multiechelon supply chains with an assembly structure firms in the supply chain are grouped into homogenous sectors nodes that contain identical firms with identical production capabilities that all produce exactly one undifferentiated product that may itself be a kit of components each sector may use several inputs to produce its product and these inputs are supplied by different sectors the production process within any sector is taken to be pure assembly in fixed proportions the number of firms in each sector is known the demand curve for the final product is assumed to be linear as are production costs in all sectors competition is modeled via a coordinated successive cournot model in which firms choose production quantities for their downstream market so as to maximize profits given prices for all inputs and all complementary products production quantities for sectors supplying the same successor are coordinated through pricing mechanisms so that complementary products are produced in the right proportions under these assumptions equilibrium prices for any multiechelon assembly network are characterized by a system of linear equations we derive closed form expressions for equilibrium quantities and prices in any two stage system i e a system with multiple input sectors and a single assembly sector we show that any assembly structure can be converted to an equivalent larger structure in which no more than two components are assembled at any node finally large structures can be solved either by direct solution of the characteristic linear equations or through an iterative reduction compression to smaller structures

investor protection optimal incentives and economic growth does investor protection foster economic growth to assess the widely held affirmative view we introduce investor protection into a standard overlapping generations model of capital accumulation better investor protection implies better risk sharing because of entrepreneurs risk aversion this results in a larger demand for capital this is the demand effect a second effect the supply effect follows from general equilibrium restrictions better protection i e higher demand increases the interest rate and lowers the income of entrepreneurs decreasing current savings and next period s supply of capital the supply effect is stronger the tighter are the restrictions on capital flows our model thus predicts that the positive effect of investor protection on growth is stronger for countries with lower restrictions cross country data provide support for this prediction as does the detailed examination of the growth experiences of south korea and india

seasonal and size anomalies in the japanese stock market little attention has been paid by the academic community in the united states to the japanese stock market and its structure japan has the second largest economy in the western world and the tokyo stock exchange tse is second only to the new york stock exchange nyse in terms of aggregate market values and sales volume analysis of the japanese stock market is useful given its relative importance but in addition examination of the japanese market may offer insights into controversies surrounding u s markets this study focuses on two such current controversies the january and size anomalies

a reexamination of the conglomerate merger wave in the 1960s an internal capital markets view one possible explanation for bidding firms earning positive abnormal returns in diversifying acquisitions in the 1960s is that internal capital markets were expected to overcome the information deficiencies of the less developed capital markets examining 392 bidder firms during the 1960s we find the highest bidder returns when financially unconstrained buyers acquire constrained targets this result holds while controlling for merger terms and for different proxies used to classify firms facing costly external financing we also find that bidders generally retain target management suggesting that management may have provided companyspecific operational information while the bidder provided capital budgeting expertise

equity carve outs and managerial discretion this study proposes a managerial discretion hypothesis of equity carve outs in which managers value control over assets and are reluctant to carve out subsidiaries thus managers undertake carve outs only when the firm is capital constrained consistent with this hypothesis firms that carve out subsidiaries exhibit poor operating performance and high leverage prior to carve outs also consistent with this hypothesis in carve outs wherein funds raised are used to pay down debt the average excess stock return of 6 63 percent is significantly greater than the average excess stock return of 0 01 percent for carve outs wherein funds are retained for investment purposes in this study we investigate the financial and operating performance of firms that undertake equity carve outs and analyze the cross section of excess stock returns around the announcement of these transactions in an equity carve out a firm offers to sell shares in a wholly owned subsidiary to the public as such a carve out can be viewed as the sale of an asset or as an equity offering schipper and smith 1986 focus on carve outs as equity offerings and compare the announcement period stock returns of carve outs with those of seasoned equity offerings in this study we view the carve out as the sale of an asset which is intended to raise funds to finance other activities of the parent or the subsidiary in viewing equity carve outs as asset sales we borrow from the work of lang poulsen and stulz 1995 who propose and test a financing hypothesis to explain the cross section of excess stock returns around announcements of asset sales the characterization of an equity carve out as a sale of assets must be tempered by the fact that certain features distinguish carveouts from outright asset sales equity carve outs are asset sales to public shareholders as opposed to a single buyer carve outs are undertaken explicitly for the purpose of raising funds in the capital market and the parent firm typically continues to hold a substantial fraction of the equity of the carved out subsidiary following the offering equity carve outs are similar to asset sales in that funds raised in the offering can be either retained within
