In this study, we investigate the effects of stock short-sale constraints on options trading by exploiting two US Securities and Exchange Commission rule changes under Regulation SHO: Rule 203 (locate and close-out requirements) and Rule 202T (temporary removal of short-sale price tests). We find that stock short selling activities decrease (increase) significantly after Rule 203 (Rule 202T) implementation, supporting the validity of Rule 203 (Rule 202T) as an exogenous increase (decrease) in short-sale constraints. Options volume increases significantly after Rule 203 went into effect and the result is more pronounced among firms with lower levels of institutional ownership and smaller options bid-ask spreads. Therefore, the evidence from Rule 203 suggests that investors may use options as substitutes for stock short sales when short selling is less feasible or more costly due to the locate and delivery requirements. In contrast, we find no significant change in the options trading volume of pilot stocks during the pilot program of Rule 202T. Overall, our results indicate that the impact of short-sale constraints on options trading varies with the types of constraints affected. 相似文献

The main purpose of this paper is to empirically model the influence of macroeconomic and financial variables on the performance
of risk capital in the US. We start our investigation using a static long-run equilibrium model. In contrast to previous studies,
we analyze the effect of several factors simultaneously within the framework of a vector error correction model (VECM). This
allows us to study short- and long-term interactions to overcome the problem of endogeneity, and to discover causal mechanisms.
The results show that the value of venture capital investments is positively related to industrial production, the exit channel
Nasdaq, and the long-term interest rate. However, the value of venture capital investments is negatively related to the short-term
interest rate. According to the short-term dynamics, VEC Granger causality confirms that only industrial production influences
venture capital performance, while venture capital returns Granger causes Nasdaq performance. 相似文献

Despite the rapid growth of Internet banking (IB), customers in developing countries still hesitate to adopt this technology and its use in the Middle East remains low. This study aims to identify and examine the factors that predict behavioural intention and adoption of IB in Jordan. Four factors – hedonic motivation, habit, self-efficacy and trust – are proposed in a conceptual model. Data was collected by means of a survey with bank customers in Jordan. Structural equation modelling (SEM) was used to analyse the data. The results strongly supported the conceptual model. Further, hedonic motivation, habit, self-efficacy and trust were all confirmed to have a significant influence on behavioural intention. Trust was found to be strongly predicted by both hedonic motivation and self-efficacy. This study provides both academics and practitioners with an insight into the factors that can be used to encourage customer adoption of IB specifically in a Middle East context. 相似文献

This paper applies Plato’s cave allegory to Enron’s success and downfall. Plato’s famous tale of cave dwellers illustrates
the different levels of truth and understanding. These levels include images, the sources of images, and the ultimate reality
behind both. The paper first describes these levels of perception as they apply to Plato’s cave dwellers and then provides
a brief history of the rise of Enron. Then we apply Plato’s levels of understanding to Enron, showing how the company created
its image and presented information to support that image, and how the public eventually emerged from the cave to realize
the truth about Enron’s actual accounting practices and financial state, which led to the corporation’s downfall. We find
Plato’s allegory both useful in analyzing the relationship between Enron and the public and instructive about the power and
moral responsibility of Enron’s executives. 相似文献

The contextual nature of the predictive power of statistically-based quarterly earnings models 总被引:2,自引:2,他引:0
We present new empirical evidence on the contextual nature of the predictive power of five statistically-based quarterly earnings
expectation models evaluated on a holdout period spanning the twelve quarters from 2000–2002. In marked contrast to extant
time-series work, the random walk with drift (RWD) model provides significantly more accurate pooled, one-step-ahead quarterly
earnings predictions for a sample of high-technology firms (n = 202). In similar predictive comparisons, the Griffin-Watts (GW) ARIMA model provides significantly more accurate quarterly
earnings predictions for a sample of regulated firms (n = 218). Finally, the RWD and GW ARIMA models jointly dominate the other expectation models (i.e., seasonal random walk with
drift, the Brown-Rozeff (BR) and Foster (F) ARIMA models) for a default sample of firms (n = 796). We provide supplementary analyses that document the: (1) increased frequency of the number of loss quarters experienced
by our sample firms in the holdout period (2000–2002) vis-à-vis the identification period (1990–1999); (2) reduced levels
of earnings persistence for our sample firms relative to earnings persistence factors computed by Baginski et al. (2003) during earlier time periods (1970s–1980s); (3) relative impact on the predictive ability of the five expectation models
conditioned upon the extent of analyst coverage of sample firms (i.e., no coverage, moderate coverage, and extensive coverage);
and (4) sensitivity of predictive performance across subsets of regulated firms with the BR ARIMA model providing the most
accurate predictions for utilities (n = 87) while the RWD model is superior for financial institutions (n = 131).

Foreign direct investment is of increasing importance in the European Union. This paper estimates the effect of taxes on foreign
direct investment (FDI) flows and on three sub-components of these flows for the countries of the enlarged European Union.
The model in the spirit of gravity equations robustly explains FDI flows between the 25 member states. Sample selection needs
to be addressed in the estimation. We show that the different subcomponents of FDI should and indeed do react differently
to taxes. After controlling for unobserved country characteristics and common time effects, the top statutory corporate tax
rate of both, source and host country, turn insignificant for total FDI and investment into equity. However, high source country
taxes clearly increase the probability of firms to re-invest profits abroad and lower the percentage of debt financed FDI.
This might reflect profit re-allocation to avoid taxes. Market size factors have the expected signs.

This research estimates fiscal impacts of Wal-Mart in Ohio from 1985 through 2003. Using a panel of counties, and accounting
for spatial autocorrelation in an instrumental variable model I estimate impact of Wal-Mart and Super-Centers on selected
revenues and transfer payments. Among the findings is that the presence of a Wal-Mart increases local commercial property
tax assessments resulting in collection increases of between $350,000 and $1.3 million. There is also an 18–43% reduction
in per capita EITC claims in a county. However, Medicaid expenditures experience growth which amount to roughly 16 additional
cases attributable to a single Wal-Mart. The magnitude and statistical certainty of these findings, suggests that local fiscal
intervention, either through incentives or a “Wal-Mart Tax” is unwarranted.
