ILLEGAL INSIDER TRADING: IS IT RAMPANT BEFORE CORPORATE TAKEOVERS?

This paper investigates the role of insider trading as an explanation for the observed pre-announcement price run-ups for takeover targets. We hypothesize that if insider trading is a significant contributor to such price run-ups, then observed run-ups should be smaller for takeovers occurring after May 1986 (the beginning of the “insider trading scandal”) relative to those occurring prior to May 1986. The evidence suggests that insider trading is not, on average, a significant contributor to pre-announcement price run-ups.     

Foreign Acquisitions in the United States and the Effect on Shareholder Wealth

The research presented here indicates that foreign acquisitions in the United States in the form of mergers, have resulted in abnormal returns to targets of nearly 22 percent, a figure not much higher than in domestic mergers. Sell-off abnormal returns have averaged nearly three percent, substantially higher than the average 0.7 to 1.66 percent in the domestic case. We find that merger abnormal returns have been substantially higher in our first subperiod (1982–84) than in the second (1985–87). For selloffs, our results are reversed-abnormal returns have been higher in the second subperiod. In cross-sample tests, we find the Japanese paying the highest merger premiums/abnormal returns, while the sell-off abnormal returns are highest when Germans are the buyers. We also find significant differences across industry samples but not across combination type samples. We do not find a significant relationship of these abnormal returns to the firm's accounting and financial variables.     

A Quantitative Assessment of the Finance–Growth–Innovation Nexus in EEA Countries: Evidence from a Multivariate VECM

This paper uses country-level data of European Economic Area countries between 1989 and 2016 to examine the interactions between economic growth, innovation, and financial market activities, with specific reference to the bond and insurance markets. Our intent is to know whether causality runs among these variables both ways, or not at all. Using a vector error correction model, the study finds that financial market activities and economic growth determine innovation activities in these countries. Additionally, the study also finds bidirectional Granger causality between financial market activities and economic growth, as well as between innovation activities and economic growth.     

Bank Ownership and Lending Behaviours: The Relevance of Community Links

Asset size does not seem to be a good predictor of bank lending behaviours. An overlooked determinant of lending may be the relationship a bank has with its local community. This article suggests that US banks owned and headquartered in a community are typically central actors in local business networks, and bank executives are intimately connected to their communities. As a result, lending decisions made by banks headquartered in the community often become influenced by the social relations and social networks of bank executives.     

Predictors of high healthcare resource utilization and liver disease progression among patients with chronic hepatitis C

Background:

Since hepatitis C virus therapy is typically prioritized for patients with more advanced disease, predicting which patients will progress could help direct scarce resources to those likely to benefit most. This study aims to identify demographics and clinical characteristics associated with high healthcare resource utilization (HRU) and liver disease progression among CHC patients.

Methods:

Using health insurance claims (January 2001–March 2013), adult patients with ≥2 CHC claims (ICD-9-CM: 070.44 or 070.54), and ≥6 months of continuous insurance coverage before and ≥36 months after the first CHC diagnosis were included. Patients with human immunodeficiency virus were excluded. Generalized estimating equations were used to identify the demographic and clinical characteristics of being in the 20% of patients with the highest HRU. Factors predicting liver disease progression were also identified.

Results:

In the study population (n?=?4898), liver disease severity and both CHC- and non–CHC-related comorbidities and conditions were strong predictors of high healthcare costs, with odds ratios (ORs; 95% confidence interval [CI]) for ≥2 CHC-related and ≥2 non-CHC-related comorbidities/conditions of 2.78 (2.48–3.12) and 2.19 (1.76–2.72), respectively. CHC- and non-CHC-related comorbidities and conditions were also strong predictors of liver disease progression with ORs (95% CI) for ≥2 CHC-related and ≥2 non-CHC-related comorbidities and conditions of 2.18 (1.83–2.60) and 1.50 (1.14–1.97), respectively.

Limitations:

Potential inaccuracies in claims data, information or classification bias, and findings based on a privately insured population.

Conclusion:

This study suggests that CHC patients with high healthcare resource utilization have a high level of comorbidity at baseline and also that non-CHC comorbidities and conditions are strong predictors of high HRU. Non-cirrhotic CHC patients with one or more comorbidities are at high risk of progressing to cirrhosis or end-stage liver disease.
