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

This study examines how foreign direct investment (FDI) affects domestic employment by using unique division-level data of Japanese firms. Contrary to most previous studies focusing on the effect of FDI on net employment growth, we decompose it into job creation (JC) and job destruction (JD) for each individual firm. We find that FDI destination plays an important role: FDI to Asia increases JC, whereas FDI to Europe/North America decreases it; furthermore JD decreases, regardless of FDI destination. A frictional search-and-matching model with heterogeneous jobs can explain the differential effects. The model provides additional predictions on JC and JD by job type, which are also empirically confirmed. 相似文献

How willingness to pay for environmental quality changes as incomes rise is a central question in several areas of environmental economics. This paper explores both theoretically and empirically whether or not the willingness to pay (WTP) for pollution control varies with income. Our model indicates that the income elasticity of the marginal WTP for pollution reduction is only constant under very restrictive conditions. Our empirical analysis tests the null hypothesis that the elasticity of the WTP for pollution control with respect to income is constant, employing a multi-country contingent valuation study of eutrophication reduction in the Baltic Sea. Our findings reject this hypothesis, and estimate an income elasticity of the WTP for eutrophication control of 0.1–0.2 for low-income respondents and 0.6–0.7 for high-income respondents. Thus, our empirical results suggest that the elasticity is not constant but is always less than one. This has implications for how benefits transfer exercises, and for theoretical explanations of the environmental Kuznets curve. 相似文献

Using daily data spanning 10 years, we establish a statistical relationship between episodic particulate-matter \((\hbox {PM}_{2.5})\) concentrations and vehicle trips in Cache Valley, Utah, and estimate an average gas-price elasticity for the region. We also estimate the benefits and costs associated with a seasonal gas tax set to reduce vehicle trips during the winter-inversion season and thereby lower health costs through concomitant decreases in the \(\hbox {PM}_{2.5}\) concentrations. We find a strong positive relationship between vehicle trips reduced and associated reductions in \(\hbox {PM}_{2.5}\) concentrations. Further, we estimate a mean gas price elasticity of approximately \(-\)0.3 in what we call a “high price variability environment.” Incorporating these results, cost-benefit analysis suggests that the social net benefit for Cache Valley associated with the imposition of a seasonal gas tax during the winter-inversion season is highly dependent upon the type of benefit estimation method used. 相似文献

The fiscal cost of the financial and economic crisis in Europe is huge. The paper provides provisional estimates of this cost
and looks at its implications for the sustainability of public finances, taking into account also the impact of aging populations.
The historical experience suggests that economic growth is persistently lowered in the aftermath of financial crisis, making
fiscal consolidation more difficult yet all the more essential. Meanwhile the timing of the exit from fiscal stimulus and
subsequent fiscal consolidation must reconcile sustainability and stabilisation goals—a delicate balancing act. The paper
will argue in favour of structural reform to boost the economic growth potential alongside fiscal consolidation. The fiscal
coordination framework in the EU, together with the Europe 2020 strategy, is seen to underpin this approach. 相似文献

Peter Boettke (2007) argues that economists need not act pluralistically in order for pluralism to thrive in the marketplace of economic ideas.
From a market process perspective, Boettke sees intellectual diversity and openness as catallactic outputs, not inputs—emergent
by-products of academic specialization and trade. To expect individual scholars to behave in a pluralistic manner is unnecessary
and “completely inappropriate” since it detracts from their central task: “to commit themselves to an approach and pursue
it doggedly, even in the face of great doubt and resistance by one’s peers” (Boettke 2007). This paper proposes a Smithian revision of Boettke’s position. The author argues that scholarly pluralism is best understood
as a constitutional rule of academic life—a virtue ethic that promotes learning and intellectual freedom by mitigating tyranny
and autarky in the republic of science. Drawing from the writings of Adam Smith, Friedrich Hayek, Deirdre McCloskey, Bruce
Caldwell, James Buchanan, Don Lavoie, and Boettke himself, the author argues that scholarly pluralism has been, and continues
to be, a necessary condition for the flourishing of Austrian economists as free, responsible, efficacious thinkers. 相似文献
