Firm size, web site content, and financial performance in the transportation industry

The transportation industry has been revolutionized by the World Wide Web with the Internet rapidly emerging as the optimal medium for the exchange of information between shippers and carriers throughout the supply chain. Despite this, many motor carrier firms may still not be placing enough emphasis on the Internet. Recent empirical research studies suggest that Internet utilization in the supply chain is significantly influenced by firm size. This study analyzes the informational and interactive content of the Top 100 U.S. motor carrier firms' web sites to examine the relationship between firm size and Internet utilization. In addition, as there is little research that assesses the payoff in terms of benefits for firms that place more emphasis on the Internet for commercial activity, secondary financial data are used to evaluate the association between Internet utilization and firm financial performance in the transportation industry.     

The error structure of time series cross-section hedonic models with sporadic event timing and serial correlation

When estimating hedonic models of housing prices, the use of time series cross-section repeat sales data can provide improvements in estimator efficiency and correct for unobserved characteristics. However, in cases where serial correlation is present, the irregular timing of sales should also be considered. In this paper we develop a model that uses information on the timing of events to account for the sporadic occurrence of events. The model presumes that the serial correlation process can be decomposed into a time-independent (event-wise) component and a time-dependent (time-wise) component. Empirical tests cannot reject the presence of sporadic correlation patterns, while simulations show that the failure to account for sporadic correlation leads to significant losses in efficiency, and that the losses from ignoring sporadic correlation when it exists are larger than losses when sporadic correlation is falsely assumed.

Intelligent Systems in Accounting,Finance and Management: ISI journal and proceeding citations,and research issues from most‐cited papers

This paper analyses the citations from Intelligent Systems in Accounting, Finance and Management that have occurred in ISI's Web of Knowledge in February 2010. I found roughly 1000 citations to the journal under 10 different journal name abbreviations, with roughly 25% of the citations occurring during 2008–2009, associated with 27 of the more frequently cited papers. Using that citation data, the H‐index and the 40 (42 with ties) most‐cited papers are presented. I found that ISI's new proceedings data appear to have a different citation pattern than ISI's journal citation data, resulting in citations to more sources, but fewer citations per source. I also examine the research methodologies and applications of the most‐cited papers in an attempt to determine what areas have been cited most and where there are potential gaps in the research.

Syndication in Venture Capital Financing

We examine syndication in venture capital (VC) investments between 1980 and 2005. We argue that VC firms syndicate investments to mitigate human capital and financial constraints within individual VC firms and to reduce uncertainty about firm value. Our results are consistent with those arguments. We find that syndication is more likely for firms in the earliest stage of development and firms in the last stage of development as private firms (when human capital investments are greatest), for firms requiring the largest amounts of financial capital, and for firms with greater growth opportunities (those that are most difficult to value).     

The value of the floor

Existing theoretical literature suggests that floor trading has discernable benefits over electronic trading. In particular floor relationships lead to a reduction in asymmetric information and hence lower spreads. The ability of floor brokers to participate in incoming order flow without revealing their supply and demand curves increases total liquidity and dampens liquidity shocks leading to lower volatility. We develop hypotheses and test them on a sample of stocks that switch from floor trading to an electronic system with fairly identical rules and pre-trade transparency. We find strong support for existing theory and our hypotheses. In particular asymmetric information and volatility are significantly higher on the electronic system. This leads to an increase in investor transaction costs which dwarfs the operational cost advantages of the electronic systems. Our results are robust to tests involving samples that control for company specific factors and market wide trends.     

Preferred risk habitat of individual investors

The preferred risk habitat hypothesis, introduced here, is that individual investors select stocks whose volatilities are commensurate with their risk aversion. The data, 1995–2000 holdings of over 20,000 clients at a large German broker, are consistent with the predictions of the hypothesis: the returns of stocks within each portfolio have remarkably similar volatilities, when stocks are sold they are replaced by stocks of similar volatilities, and the more risk-averse customers indeed hold less volatile stocks. Greater volatility specialization is associated with lower Sharpe ratios, primarily because more specialized investors hold fewer stocks and thereby expose themselves to more unsystematic risk.     

The level and quality of Value-at-Risk disclosure by commercial banks

In this paper we study both the level of Value-at-Risk (VaR) disclosure and the accuracy of the disclosed VaR figures for a sample of US and international commercial banks. To measure the level of VaR disclosures, we develop a VaR Disclosure Index that captures many different facets of market risk disclosure. Using panel data over the period 1996–2005, we find an overall upward trend in the quantity of information released to the public. We also find that Historical Simulation is by far the most popular VaR method. We assess the accuracy of VaR figures by studying the number of VaR exceedances and whether actual daily VaRs contain information about the volatility of subsequent trading revenues. Unlike the level of VaR disclosure, the quality of VaR disclosure shows no sign of improvement over time. We find that VaR computed using Historical Simulation contains very little information about future volatility.     

Loan growth and riskiness of banks

We investigate whether loan growth affects the riskiness of individual banks in 16 major countries. Using Bankscope data from more than 16,000 individual banks during 1997–2007, we test three hypotheses on the relation between abnormal loan growth and asset risk, bank profitability, and bank solvency. We find that loan growth leads to an increase in loan loss provisions during the subsequent three years, to a decrease in relative interest income, and to lower capital ratios. Further analyses show that loan growth also has a negative impact on the risk-adjusted interest income. These results suggest that loan growth represents an important driver of the riskiness of banks.     

Mergers,strategic investments and antitrust policy

Established firms can diversify into new markets in two distinct modes: through internal development or through conglomerate merger. Building on a dynamic three-stage bargaining model with variable threats, this paper shows that a lenient antitrust position toward horizontal mergers can induce established firms that would otherwise not have entered to enter via conglomerate merger. The vigor of antitrust enforcement toward horizontal mergers also affects the conglomerate acquisition price but it does not influence the choice of entry mode. Finally, the paper brings to light a heretofore neglected avenue through which conglomerate mergers can increase welfare.
