探讨高科技企业研发投入的同群效应,特别是企业面临的市场环境不确定性,以及体现制度环境的知识产权保护对高科技企业研发投入同群效应的影响。实证分析沪深A股2009—2017年高科技上市公司数据,结果表明:①高科技企业研发投入存在显著的同群效应;②环境不确定性显著负向调节高科技企业研发投入的同群效应,即环境不确定性弱化了企业研发投入的行业趋同;③知识产权保护显著正向调节高科技企业研发投入的同群效应,即知识产权保护强化了企业研发投入的行业趋同。结论丰富了企业研发投入同群效应研究成果,为考察企业所处外部市场与制度环境对企业研发投入同群效应的影响提供了新视角。 相似文献

The assets under management of investment funds have soared in recent years, triggering a debate on their possible implications for financial stability. We contribute to this debate assessing the asset price impact of fire sales in a novel partial equilibrium model of euro area funds and banks calibrated over the period between 2008 and 2017. An initial shock to yields causes funds to sell assets to address investor redemptions, while both banks and funds sell assets to keep their leverage constant. These fire sales generate second-round price effects. We find that the potential losses due to the price impact of fire sales have decreased over time for the system. The contribution of funds to this impact is lower than that of banks. However, funds’ relative contribution has risen due to their increased assets under management and banks’ lower leverage and rebalancing towards loans. Should this trend continue, funds will become an increasingly important source of systemic risk. 相似文献

ABSTRACT We explore the link between third-party certification (venture capital backing, analyst following and having a top underwriter), and post-IPO acquisition activity through the reduction in valuation uncertainty channel. In a sample of 2,424 U.S. IPOs, we find that third-party certification facilitates post-IPO acquisitions. The certified firms are both more likely and conduct acquisitions sooner after the IPO. Our results support the notion that third-party certification reduces post-IPO valuation uncertainty and thereby facilitates a more efficient acquisition strategy. 相似文献

In this paper, we propose a goal-based investment model that is suitable for personalized wealth management. The model only requires a few intuitive inputs such as size of wealth, investment amount, and consumption goals from individual investors. In particular, a priority level can be assigned to each consumption goal and the model provides a holistic solution based on a sequential approach starting with the highest priority. This allows strict prioritization by maximizing the probability of achieving higher priority goals that are not affected by goals with lower priorities. Furthermore, the proposed model is formulated as a linear program that efficiently finds the optimal financial plan. With its simplicity, flexibility, and computational efficiency, the proposed goal-based investment model provides a new framework for automated investment management services. 相似文献

This study contributes to the literature by making a first step toward implementing a comprehensive internally coherent measurement of systemic risk in a country. It measures systemic risk and the ensuing conditional contingent liabilities of the sovereign stemming from Luxembourg’s Other Systemically Important Institutions (OSIIs), the Global Systemically Important Banks (G-SIBs) to which they belong, the investment funds sponsored by the OSIIs, the household and the non-financial corporate sectors. The ensuing estimated systemic contingent claims are included in a stochastic version of the general government’s balance sheet to gauge their impact on the country’s sovereign risk. Results indicate that time-varying conditional implicit guarantees from OSSIs are larger than those from G-SIBs and investment funds, while systemic risk stemming from the household and non-financial corporate sectors is moderate. The robustness of the sovereign is not drastically affected by systemic risk stemming from the rest of the economy. However, illustrating the so-called “deadly embrace”, sovereign risk would significantly rise as a result of a historically plausible increase in sovereign assets’ value volatility combined with an economy-wide shock. The main policy implication is that financial stability stands on two columns, a resilient financial sector and a sustainable fiscal position. 相似文献

This paper investigates the extent to which domestic investment in East Asian countries is financed by domestic, (East Asian) regional and global savings in order to infer the relative importance of regional vs. global capital markets in East Asia. Panel regression results show that regional saving in East Asia plays a much more important role than global saving in financing investment in the region. The results suggest that global capital flows, despite its huge volume in East Asia, does not contribute to proper investment financing. The results also show that Japanese saving has significant effects on regional investment but Chinese saving does not. 相似文献

Optimal government bond supply is examined under asymmetric information and safe asset scarcity. Corporations issue junk debt when demand for safe debt is high since uninformed investors then migrate to risky overheated debt markets. Uninformed demand stimulates informed speculation, driving debt prices toward fundamentals, encouraging pooling at high leverage. As borrower of first resort, government can issue bonds, siphoning off uninformed demand for risky corporate debt, reducing wasteful informed speculation. Government bonds eliminate pooling at high leverage or improve risk sharing in such equilibria. Optimal government bond supply is increasing in demand for safe assets and non-monotonic in marginal Q. 相似文献

Why do diversified firms hold significantly less cash than focused firms? We study this question using a dynamic model of corporate investment, saving, and diversification decisions. We find that investment dynamics are more important in explaining the cash differences than financing frictions. More efficient internal capital markets increase cash differences and are especially valuable when a firm diversifies or refocuses. Contrary to static models, more diverse conglomerates have lower cash differences. Endogenous selection (diversifying firms are larger and have better growth opportunities) accounts for 68% of the cash difference, and the diversification event itself reduces cash holdings by 32%. 相似文献
