Investor attention,firm-specific characteristic,and momentum: A case of the Korean stock market

This study examines the sources of negative momentum profits by combining investor attention and the properties of common and firm-specific factors. We choose the Korean stock market as a good case to characterize the negative momentum profits identified in Asia. In both portfolio and stock analyses, a method is devised to generate return data involving the property of each common and firm-specific factor within stock groups by investor attention. This study found significant negative momentum profits within the stock group with high investor attention. This momentum effect is highly dependent on the reversed performance of the past loser portfolio, not the continued performance of the past winner portfolio, and this reversal is strongly attributable to the properties of firm-specific factors, and not those of common factors. These results are robustly consistent regardless of changes in empirical design and the consideration of influence factors, market dynamics, and other stock markets.

对于发展中国家来说,资本流入虽然通常被作为可能促进本国经济发展的积极因素,但是它也蕴含着对东道国的严重负面影响。本文试图通过理论和经验数据两方面的分析,说明近些年来大量的资本流入在中国所自我创造的隐蔽的套利空间。而在私人资本通过该空间获利时,却可能对中国经济和金融造成严重冲击。     

Are firms accessing venture funding more financially constrained? New evidence from capital structure adjustments

We analyze whether firms that receive venture capital (VC) at a later date face more financial constraints than a one-by-one matched sample of firms that did not receive VC funding (control group). The aim is to check whether their financial flexibility explains why they decide to seek external equity funding. In contrast with other papers, which focus on the sensitivity of investments to cash flow, we study this issue by applying a dynamic model to analyze the speed of adjustment to their target debt levels prior to receiving the first VC investment. We analyze a representative sample of 237 Spanish unlisted firms that received VC between 1995 and 2007 and its corresponding control group. We find that firms that receive VC funding show a significantly lower speed of adjustment than their matched peers before the initial VC round. It seems that the former are more concerned about funding the required investments than about adjusting the firm's debt ratio to a target level. Our results confirm the role of VC in filling the equity gap in constrained unlisted firms. From a capital structure perspective, VC may become a tool for these companies to balance their capital structure in a growth process.     

The Stock Market Reaction to Investment Announcements: The Case of Individual Capital Expenditure Projects

In this paper we provide novel evidence about the market reaction to capital expenditure announcements in the UK using a sample of nearly 500 disclosures made between 1989 and 1991. First, we show that the market reaction to joint venture announcements is significantly positive, whilst similar announcements from individual companies do not elicit any response. Second, we find that the market reaction to single company investments is positively related to the size of the expenditure, but only for projects which immediately generate cash. Finally, we report that the variability in the market response to announcements which follow large cash inflows is significantly lower than the variability in investors' reactions to announcements which are not preceded by such inflows.     

Chaebol,Investment Opportunity Set and Corporate Debt and Dividend Policies of Korean Companies

This paper examines explanations for the association between Korean Chaebol, which are giant conglomerates supported by various government initiatives, and corporate debt and dividend policies. Unlike in the US, the Korean corporate sector is dominated by the Chaebol which are characterized by concentrated family ownership, political affiliation and bank ownership. These institutional arrangements are likely to encourage more debt financing. In addition, the study also investigates whether firms with more growth options measured in terms of the investment opportunity set (IOS) have lower leverage and dividends. Results using observations from 411 Korean firms showed that for a fixed level of growth opportunities, Chaebol carry higher levels of debt. Results also show that growth options were negatively associated with leverage and dividends. No association, however, was found between Chaebol and dividends.     

Evaluating asset pricing models using the second Hansen-Jagannathan distance

We develop a specification test and a sequence of model selection procedures for non-nested, overlapping, and nested models based on the second Hansen-Jagannathan distance, which requires a good asset pricing model to not only have small pricing errors but also be arbitrage free. Our methods have reasonably good finite sample performances and are more powerful than existing ones in detecting misspecified models with small pricing errors but are not arbitrage-free and in differentiating models that have similar pricing errors of a given set of test assets. Using the Fama and French size and book-to-market portfolios, we reach dramatically different conclusions on model performances based on our approach and existing methods.     

中国农产品加工业跨越式发展的竞争态势分析

农产品加工业的较快发展,已成为我国农村经济和国民经济中极具潜力的新的增长点,成为我国由农业大国走向农业强国的突破口。但目前中国农产品加工业不仅落后与国外发达国家的发展水平,而且滞后于产业自身的发展水平。本文从农产品加工业自身的优势和劣势,面临的外部机遇和挑战方面,分析了中国农产品加工业跨越式发展的紧迫性和可行性,指出跨越式发展是中国农产品加工业的必由之路。     

How quickly is temporary market inefficiency removed?

I provide evidence on the length of time it takes for arbitrageurs to exploit attractive investment opportunities. A unique data set from the Internet sports betting market allows me to focus on the speed of investor response in an environment that is not affected by the joint hypothesis problem. The market does not instantly converge to an efficient level after mispricing occurs, but the adjustment process is rapid. Arbitrageurs remove many of these opportunities within minutes of them being created and the majority are gone within an hour. Arbitrage opportunities that are more difficult to find last for longer.     

Long-run underperformance following private equity placements: The role of growth opportunities

Our results show that the post-offering performance of private equity issuers is related to growth opportunities. We find significant long-run underperformance in stock returns following private placements only for firms with high Tobin's q. High-q firms experience not only poor stock price performance but also poor operating performance. Low-q firms, in contrast, do not display significant stock price or operating underperformance. We further examine three potential explanations for this relation: over-investment in assets by managers, investor skewness preference, and over-optimism about earnings prospects. Our results are consistent with the view that investors are overly optimistic about the prospects of high growth firms.
