New growth theories emphasize the role played by innovation in promoting economic growth. Since it is difficult to quantify the amount of innovation undertaken in an economy, there is little available empirical evidence assessing the contribution made by innovation to growth, in contrast to abundant evidence on the role of physical capital accumulation in the growth process. In this paper patent data are used to proxy the amount of innovation undertaken in an economy. The patent data are used to explore two questions. First, how important is innovation to economic growth in Australia, and second, are reductions in innovations sourced in Australia offset by increases in foreign sourced innovations in Australia? 相似文献

We show that market-maker balance sheet and income statement variables explain time variation in liquidity, suggesting liquidity-supplier financing constraints matter. Using 11 years of NYSE specialist inventory positions and trading revenues, we find that aggregate market-level and specialist firm-level spreads widen when specialists have large positions or lose money. The effects are nonlinear and most prominent when inventories are big or trading results have been particularly poor. These sensitivities are smaller after specialist firm mergers, consistent with deep pockets easing financing constraints. Finally, compared to low volatility stocks, the liquidity of high volatility stocks is more sensitive to inventories and losses. 相似文献

We examine how accounting transparency and investor base jointly affect financial analysts' expectations of mispricing (i.e., expectations of stock price deviations from fundamental value). Within a range of transparency, these two factors interactively amplify analysts' expectations of mispricing—analysts expect a larger positive deviation when a firm's disclosures more transparently reveal income‐increasing earnings management and the firm's most important investors are described as transient institutional investors with a shorter‐term horizon (low concentration in holdings, high portfolio turnover, and frequent momentum trading) rather than dedicated institutional investors with a longer‐term horizon (high concentration in holdings, low portfolio turnover, and little momentum trading). Results are consistent with analysts anticipating that transient institutional investors are more likely than dedicated institutional investors to adjust their trading strategies for near‐term factors affecting stock mispricings. Our theory and findings extend the accounting disclosure literature by identifying a boundary condition to the common supposition that disclosure transparency necessarily mitigates expected mispricing, and by providing evidence that analysts' pricing judgments are influenced by their anticipation of different investors' reactions to firm disclosures. 相似文献

Optimal capital budgeting criteria now exist for a variety of applications when project cash flows (or present values) evolve in terms of the well-known geometric Brownian motion. However, relatively little is known about the capital budgeting procedures that ought to be implemented when cash flows are generated by stochastic processes other than the geometric Brownian motion. Given this, our purpose here is to develop optimal investment criteria for capital projects with cash flows that evolve in terms of a continuous time branching process. Branching processes are compatible with an empirical phenomenon known as 'volatility smile'. This occurs when there are systematic fluctuations in the implied volatility of a capital project's cash flows as the cash flow grows in magnitude. A number of studies have shown that this phenomenon characterizes the cash flow streams of the capital projects in which firms typically invest. We implement optimal capital budgeting procedures for both the continuous time branching process and the geometric Brownian motion using cost and revenue data for the Stuart oil shale project in central Queensland, Australia. This example shows that significant differences can arise between the optimal investment criteria for cash flows based on a branching process and those based on the geometric Brownian motion. This underscores the need for the geometric Brownian motion broadly to reflect the way a given capital project's cash flows actually evolve if serious errors in valuation and/or capital budgeting decisions are to be avoided. 相似文献

This study examines willingness to repurchase a Toyota among 335 Toyota owners, 246 who had participated in a class action suit against Toyota and 89 who had not participated. It also examines attitudes toward auto dealers and manufacturers and includes a psychographic measure of global consumer loyalty. Respondents were interviewed one to two years after participants had received a cash settlement to compensate for illegal overcharging. Multivariate analysis indicates that compared to nonparticipants, settlement participants, especially those satisfied with the settlement, were more willing to repurchase a Toyota and were less positive in their attitudes toward the Toyota manufacturer. Positive attitudes toward the Toyota manufacturer and dealers were associated with higher repurchase willingness, while positive attitudes toward other dealers and manufacturers were associated with lower repurchase willingness. Consumer loyalty was associated with higher repurchase willingness. These findings and their implications are discussed in terms of several theoretical frameworks. 相似文献

When private firms are acquired, buyers commonly rely on seller financing and earnouts. Using a novel database of private acquisitions, I find that seller financing and earnouts become more common as information asymmetry increases between the acquirer and the target. Financial statement audits of the targets attenuate these results, which suggests that audits decrease information asymmetry in firm acquisitions. Seller-financed acquisitions also close faster and at higher prices, reducing the private firm discount. These findings suggest that these contract structures are an important channel through which privately held firms mitigate adverse selection that arises from information asymmetry. 相似文献

We compare fees charged by investment banks for conducting IPOs in the United States and Europe. In recent years, the “7% solution,” as documented by Chen and Ritter (2000) , has become even more prevalent in the United States, and is now the norm for IPOs raising up to $250 million. The same banks dominate both markets, but European IPO fees are roughly three percentage points lower, are much more variable, and have been falling. We review explanations for the gap in spreads and find the evidence consistent with strategic pricing. U.S. issuers could have saved over $1 billion a year by paying European fees. 相似文献

We generalize the unobserved components (UC) model to allow the permanent component to have different dynamics than the transitory components when decomposing U.S. economic activity using a multivariate UC model of (log) output, consumption, and investment. We find that these proposed dynamics in the permanent component are statistically significant and distinct from those of the transitory components. Our approach provides an alternative explanation for the growth cycles identified by Comin and Gertler ( 2006 ) that is related to the cyclical movements in technology, in a framework consistent with the Beveridge and Nelson ( 1981 ) decomposition. 相似文献

This study tests the tax-induced trading hypothesis as an explanation of the turn-of-the-year anomaly using Canadian and U.S. intraday data. Since the Canadian tax year-end precedes the calendar year-end by five business days, tax effects may be isolated. We find the anomaly is related to the degree of seller-and buyer-initiated trading and depends upon the incidence of the taxation year-end. Seller-initiated transactions (at bid prices) dominate until the tax year-end after which buyer-initiated trades (at ask prices) dominate. The anomaly is a function of bid-ask prices. 相似文献
