Dynamics of analysts' coverage and the firms' information environment

The main goal of this paper is to study analysts' coverage of stocks. Through a series of ordered probit regressions the paper studies the relationship between changes in coverage and the information environment of a firm.Coverage decreases on average with higher errors in estimation. The data also shows that coverage is less likely to decrease for physically large firms, but more likely to decrease for firms with high lagged market value. Higher past revisions to the predictions also decrease coverage, showing a real cost of uncertainty.     

Information risk and credit contagion

This paper demonstrates a positive relationship between information risk and the credit contagion effect. We use abnormal changes in the Credit Default Swaps (CDS) spreads to measure the contagion effect, and the dispersion of analyst forecasts as a proxy for information risk. We find that firms with higher information risk suffer a greater contagion effect that occurs in advance to the credit default events. This finding is robust under controls of key firm-specific characteristics and general condition of stock and credit markets.

Labor market fluctuations in the small and in the large

Shimer's calibrated version of the Mortensen–Pissarides model generates unemployment fluctuates much smaller than the data. Hagedorn and Manovskii present an alternative calibration that yields fluctuations consistent with the data, but this has been challenged by Costain and Reiter, who say it generates unrealistically big differences in unemployment from the differences in policy we see across countries. We argue this concern might be unwarranted, because one cannot assume that elasticities relevant for small changes work for large changes. Models with fixed factors in market or household production can generate large effects from small changes and reasonable effects from large changes. This is reminiscent of attempts to improve the labor market in the Kydland–Prescott model, especially ones incorporating household production, like Benhabib, Rogerson, and Wright.

The effects of entrepreneurial orientation and marketing information on the performance of SMEs

In this study, we investigate the effects of entrepreneurial orientation and marketing information on the performance of small and medium-sized enterprises. We build and test a causal model using data obtained from Singaporean entrepreneurs and find support for most of our hypotheses. The results indicate that entrepreneurial orientation plays an influential role on the acquisition and utilization of marketing information, and also has a direct effect on firm performance. The utilization of information regarding marketing mix decisions (particularly the Promotion and Place elements) positively affects firm performance, and it partially mediates the relationship between entrepreneurial orientation and firm performance. The implications and future research directions are discussed.     

Monitoring process quality in off-shore outsourcing: A model and findings from multi-country survey

We investigate how recent advances in information technology and telecommunications have led to real-time monitoring of processes at the site of the provider by a buyer located across the globe. We construct a game-theoretic model of the dynamics of the buyer–supplier interaction in the presence of moral hazard and incomplete contracting. We derive the Minimum Quality Threshold (MQT) below which the provider's output will certainly be inspected. Our findings show that the buyer can pick a level of monitoring and thereby force the provider to exceed the quality level of the MQT in output quality and avoid costly and wasteful inspection. Finally, our model explains why the production of processes that are complex and more prone to errors are actually monitored less by the buyers. We furnish the results of a comprehensive, multi-year, multi-country survey of the efficacy of monitoring in off-shore outsourcing projects and demonstrate strong empirical support for the findings of the model.

Identifying M&A targets and the information content of VC/PEs

The information gap in the M&A market hinders acquirers from effectively identifying high-quality targets. We examine whether VC/PEs convey information content in the M&A market and whether acquirers can use such information to identify high-quality targets. We show that VC/PEs have significant information content and can signal high-quality target companies via “certification”. When acquirers lack acquisition experience and targets are located in inferior information environments, VC/PE “certification” is more significant. The better reputation a VC/PE has, the more information it conveys. Syndicate VC/PEs convey stronger information than independent VC/PEs. We also find that acquirers do not pay higher premiums for high-quality targets. Overall, our results suggest that VC/PEs have value relevance in the M&A market, confirming their “certification” role. We present means for acquirers to select high-quality targets and investors to build efficient portfolios.
