Abstract:  Loan announcement effects for 152 Canadian companies are examined to investigate the efficiency of monitoring by banks facing lender environmental liability. Market reaction to the announcement of bank debt to 'environmental' firms is more positive and significant than for 'non-environmental' firms and, for firms in industries with a higher likelihood of experiencing spill events, is more positive and significant, reinforcing earlier results that establish a relationship between specific loan/borrower characteristics and announcement period excess returns and providing further evidence on the 'uniqueness' of bank loans by demonstrating the superior ability of banks to monitor corporate borrowers exposed to environmental liability.  相似文献

The paper asks the question – as time series analysis moves from consideration of conditional mean values and variances to unconditional distributions, do some of the familiar concepts devised for the first two moments continue to be helpful in the more general area? Most seem to generalize fairly easy, such as the concepts of breaks, seasonality, trends and regime switching. Forecasting is more difficult, as forecasts become distributions, as do forecast errors. Persistence can be defined and also common factors by using the idea of a copula. Aggregation is more difficult but causality and controllability can be defined. The study of the time series of quantiles becomes more relevant.  相似文献

Two of the main forces driving European emigration in the late nineteenth century were real wage gaps between sending and receiving regions and demographic booms in the low‐wage sending regions. Our new estimates of net migration for the countries of sub‐Saharan Africa show that exactly the same forces driving African across‐border migration are at work today. The results suggest that rapid growth in the cohort of potential young emigrants, population pressure on the resource base, and slow economic growth are likely to intensify the pressure for migration out of Africa and into high‐wage OECD countries over the next two decades.  相似文献

Outsourcing is becoming a major option in British business, including the financial services industry, and it raises a number of ethical considerations. The author of this major ethical study contends that "Outsourcing seems to present a particular threat to employees ... because of the factors which have led to outsourcing and the way in which it tends to work." Mike Henderson is an Associate of the Chartered Institute of Bankers and Senior Lecturer in Financial Services in the School of Financial Studies and Law of Sheffield Hallam University, City Campus, Pond Street, Sheffield S1 1WB, England.  相似文献

In this paper we analyze the properties of price equilibria in a duopoly market where firms sell vertically differentiated products, consumers being uncertain about which firm sells which quality. Both existence and properties of price equilibria are characterized by the beliefs of the consumers' population about the distribution of quality between firms.  相似文献
