We create a database of company codes of ethics from firms listed on the Standard & Poor’s 500 Index and, separately, a sample of small firms. The SEC believes that “ethics codes do, and should, vary from company to company.” Using textual analysis techniques, we measure the extent of commonality across the documents. We find substantial levels of common sentences used by the firms, including a few cases where the codes of ethics are essentially identical. We consider these results in the context of legal statements versus value statements. While legal writing often mandates duplication, we argue that value-based statements should be held to a higher standard of originality. Our evidence is consistent with isomorphic pressures on smaller firms to conform. 相似文献

We exploit the information derived from geographical coordinates to endogenously identify spatial regimes in technologies that are the result of a variety of complex, dynamic interactions among site-specific environmental variables and farmer decision making about technology, which are often not observed at the farm level. Controlling for unobserved heterogeneity is a fundamental challenge in empirical research, as failing to do so can produce model misspecification and preclude causal inference. In this article, we adopt a two-step procedure to deal with unobserved spatial heterogeneity, while accounting for spatial dependence in a cross-sectional setting. The first step of the procedure takes explicitly unobserved spatial heterogeneity into account to endogenously identify subsets of farms that follow a similar local production econometric model, i.e. spatial production regimes. The second step consists in the specification of a spatial autoregressive model with autoregressive disturbances and spatial regimes. The method is applied to two regional samples of olive growing farms in Italy. The main finding is that the identification of spatial regimes can help drawing a more detailed picture of the production environment and provide more accurate information to guide extension services and policy makers. 相似文献

This paper provides evidence that the managerial effect is a key determinant of firms’ cost of capital, in the context of private debt contracting. Applying the novel empirical method developed by an earlier study to a large sample that tracks the job movement of top managers, we find that the managerial effect is a critical and significant factor that explains a large part of the variation in loan contract terms more accurately than firm fixed effects. Additional evidence shows that banks “follow” managers when they change jobs and offer loan contracts with preferential terms to their new firms. 相似文献

Racetrack and sports betting markets have been researched extensively with respect to the question of market efficiency. In contrast to the consistently observed favourite–longshot bias found in racetrack betting markets, it has been shown that gamblers in the market for Major League Baseball games reveal the opposite behaviour. This paper updates the previous study with ten years of additional data for the 1990–99 seasons. The strength of the reverse favourite–longshot bias is virtually identical to the original paper. The result suggests that, contrary to most reported inefficiencies in gambling markets, this bias appears to be permanent. 相似文献

Panel data methods for fractional response variables with an application to test pass rates 总被引:1,自引:0,他引:1
We revisit the effects of spending on student performance using data from the state of Michigan. In addition to exploiting a dramatic change in funding in the mid-1990s and subsequent nonsmooth changes, we propose nonlinear panel data models that recognize the bounded nature of the pass rate. Importantly, we show how to estimate average partial effects, which can be compared across many different models (linear and nonlinear) under different assumptions and estimated using many different methods. We find that spending has nontrivial and statistically significant effects, although the diminishing effect is not especially pronounced. 相似文献

We study the impact of firms’ abnormal business operations on their future crash risk in stock prices. Computed based on real earnings management (REM) models, firms’ deviation in real operations (DROs) from industry norms is shown to be positively associated with their future crash risk. This association is incremental to that between discretionary accruals (DAs) and crash risk found by prior studies. Moreover, after Sarbanes–Oxley Act (SOX) of 2002, DRO’s predictive power for crash risk strengthens substantially, while DA’s predictive power essentially dissipates. These results are consistent with the prior finding that managers shift from accrual earnings management to REM after SOX. We further develop a suspect-firm approach to capture firms’ use of DRO for REM purposes. This analysis shows that REM-firms experience a significant increase in crash risk in the following year. These findings suggest that the impact of DRO on crash risk is at least partially through REM. 相似文献

We investigate the relationship between Chief Executive Officer (CEO) compensation and firm innovation and find that long‐term incentives in the form of options, especially unvested options, and protection from managerial termination in the form of golden parachutes are positively related to corporate innovation, and particularly to high‐impact, exploratory (new knowledge creation) invention. Conversely, non‐equity pay has a detrimental effect on the input, output and impact of innovation. Tests using the passage of an option expensing regulation (FAS 123R) as an exogenous shock to option compensation suggest a causal interpretation for the link between long‐term pay incentives, patents and citations. Furthermore, we find that the decline in option pay following the implementation of FAS 123R has led to a significant reduction in exploratory innovation and therefore had a detrimental effect on innovation output. Overall, our findings support the idea that compensation contracts that protect from early project failure and incentivize long‐term commitment are more suitable for inducing high‐impact corporate innovation. 相似文献
