Are corporate governance and bank monitoring substitutes: Evidence from the perceived value of bank loans

Journal of Corporate Finance 2008 14(4), 475-483
We extend the literature regarding the importance of corporate governance and bank monitoring by examining the association between loan announcement wealth effects and the corporate governance characteristics of the borrowers. Using a sample of over 800 commercial loan announcements over a period of more than 20 years we find that loan announcements are more likely to have positive wealth effects for firms with weak internal corporate governance. However, we also find that this relation between perceived bank monitoring and board independence and incentive-based pay exists only for firms with weak external governance, specifically the market for corporate control.

Non-White Poverty and Macroeconomy: The Impact of Growth

American Economic Review 2008 98(2), 398-402
Although poverty research has a very long history in the social sciences, serious debate on the sufficiency of economic growth to eliminate poverty was rekindled by the inception of the “War on Poverty” by the Kennedy and Johnson Administrations during the early 1960s. Forty years later, the measurement of growth’s effect on poverty remains an important input to the policy question of whether, how much, and how govern ment efforts should address poverty reduction. Early work by Henry J. Aaron (1967) found that poverty among certain groups seemed highly sensitive to economic growth, while other groups were barely affected. Subsequent researchers have realized that poverty has a spa tial as well as a demographic dimension, and more recent work has examined poverty by “race and region” using disaggregated time series. The present study further refines the examination of poverty by racial/ethnic group and region by investigating the impact of economic progress on poverty across black, Hispanic, and white populations measured over 35 years at the level of the census region. To our knowledge, this is the first research to study all three of these groups using regional data. A regional analysis is important because the North, Midwest, South, and West have had different industrial structures and different economic histories over the last three decades. As shown in Figure 1, regional poverty rates of blacks and Hispanics relative to whites are quite different. Moreover, regional differences exist in the levels and growth rates of real per capital GDP, in the secular decline in manufac turing, and in the pattern of the unemployment rate. In addition to economic events, we control Non-White Poverty and Macroeconomy: The Impact of Growth

Asymmetric effect of basis on dynamic futures hedging: Empirical evidence from commodity markets

Journal of Banking & Finance 2008 32(2), 187-198
The dynamic minimum variance hedge ratios (MVHRs) have been commonly estimated using the Bivariate GARCH model that overlooks the basis effect on the time-varying variance–covariance of spot and futures returns. This paper proposes an alternative specification of the BGARCH model in which the effect is incorporated for estimating MVHRs. Empirical investigation in commodity markets suggests that the basis effect is asymmetric, i.e., the positive basis has greater impact than the negative basis on the variance and covariance structure. Both in-sample and out-of-sample comparisons of the MVHR performance reveal that the model with the asymmetric effect provides greater risk reduction than the conventional models, illustrating importance of the asymmetric effect when modeling the joint dynamics of spot and futures returns and hence estimating hedging strategies.
