This study investigates the performance of analysts when they match the asymmetric timeliness of their earnings forecast revisions (i.e., asymmetric forecast timeliness) with the asymmetric timeliness of firms’ reported earnings (i.e., asymmetric earnings timeliness). We find that better timeliness‐matching analysts produce more accurate earnings forecasts and elicit stronger market reactions to their forecast revisions. Further, better timeliness‐matching analysts issue less biased earnings forecasts, more profitable stock recommendations and have more favorable career outcomes. Overall, our results indicate that analysts’ ability to incorporate conditional conservatism into their earnings forecasts is an important reflection of analyst expertise and professional success.  相似文献

Research Summary: Combining studies on real options theory and economic short‐termism, we propose that, depending on CEOs’ career horizons, CEOs have heterogeneous interests in strategic flexibility, and thus, have different incentives to make real options investments. We argue that compared to CEOs with longer career horizons, CEOs with shorter career horizons will be less inclined to make real options investments because they may not fully reap the rewards during their tenure. In addition, we argue that long‐term incentives and institutional ownership will mitigate the relationship between CEOs’ career horizons and real options investments. U.S. public firms as an empirical setting produced consistent evidence for our predictions. Our study is the first to theoretically explain and empirically show that a CEO's self‐seeking behavior will impact real options investments. Managerial Summary: This article helps to explain how a CEO's self seeking‐behavior may shape a firm's real option investment, which could result in different level of strategic flexibility. We argue that CEOs with short career horizons have less time to exercise their firms’ real options, which should lower the investments in the firms’ real options portfolios relative to CEOs with long career horizons. We study a sample of U.S. public firms and find strong evidence that a CEO's expected tenure in the firm is positively related to the real options investments at the firm level. We find that this agency issue can be mitigated by adopting appropriate corporate governance mechanisms such as long‐term incentives and institutional investors.  相似文献

A recent study by Fitza argued that the prior estimates of the Chief Executive Officer (CEO) effect are conflated with events outside the CEO's control, are largely the result of random chance, and that the true CEO effect is smaller than has been previously estimated. We suggest that the empirical methodology employed by Fitza to support these claims substantially overstates the “random chance” element of the CEO effect. We replicate Fitza's findings, highlight methodological issues, offer alternative conclusions, and using multilevel modeling (MLM), suggest that his analyses mischaracterize the CEO effect.

Historical simulations of urban residential growth in Baltimore and Houston based on a model of the growth process which has two distinct components are presented. The vintage component utilizes the growth of income and population, and an assumption that housing is putty-clay, to predict the age distribution of the housing stock in each period. The spatial component of the model determines where this housing construction will take place according to (1) housing is built on vacant land and (2) the pattern of construction obeys the rules of the standard monocentric models. Housing is demolished when economically obsolete. The putty-clay (vintage) aspect of the model produces fairly accurate city-wide vintage distributions, but there is much more mixing of vintages and income (in Baltimore) by location than predicted, even under monocentric assumptions most favorable to mixing.  相似文献

The semiconductor industry in Taiwan has successfully developed over the past 20 years. The development of the industry can be featured by a spiral‐type industrial policy deployment of the state with special emphasis on R&;D and human resource development at public institutes and mobilization and organization of overseas human resources. All in all, the role played by the state has not been market‐intervention but the coordination of various systems functioning in the private sector.  相似文献

We examine the implications of changing competitive dynamics in global information and communications technology (ICT) markets for government demand-steering policies whose goal is local rents. Both computing and telephony are undergoing changes in global industry structure and changes in the nature of competition. The convergence of computing and telephony and the rapid technological change (and accompanying technological uncertainty) driving this convergence reinforce trends toward vertical competition. The emergence of global ICT markets lowers entry barriers, likely encouraging government-supported local entrants into global ICT markets. There are, however, strongly offsetting disadvantages. The underlying economics of ICT markets under vertical competition will work to reinforce the dominant position of U.S.-based incumbents in many segments. The prospects for exports, command of rent-related standards, and large rents from exports are not very bright. We expect to see far more demand-steering attempts than successes. J. Japan. Int.

Retail futures traders face uncertainty regarding the price they will obtain when trading. This price surprise, known as slippage, can be substantial. Using unique data from an introducing brokerage for Chicago Board of Trade (CBOT) wheat, corn, and soybean futures contracts, we quantify time-to-clear and the magnitude of slippage. We then identify factors that affect these trade quality measures. Finally, we analyze individual trader choice between market and limit orders and find that the likelihood of placing limit orders, where regulations protect traders from slippage, is greater when order and market characteristic indicate that adverse slippage is likely.  相似文献
