Memo To The Sec On The Proposed Rule On Disclosure Of Payments By Resource Extraction Issuers, Perrine Toledano

Columbia Center on Sustainable Investment Staff Publications

CCSI strongly supports the transparency of contracts and tax flows. CCSI shares the belief of many stakeholders that transparency is essential to leverage extractive industries for sustainable development and is in the mutual interest of all stakeholders. However, some industry players continue to voice the concern that increased transparency would be harmful for their business. Therefore, CCSI is working to also establish the business case for transparency.

In one such case, some industry players have been lobbying against the regulations developed by the Security and Exchange Commission to implement the mandatory disclosure provisions of the Dodd Frank Wall Street Reform ...

The Australian government is rapidly increasing aid to Africa. But the real story about the country's engagement in Africa is the massive investment by Australian companies in extractive industries.

The volatility of share returns for individual companies increased sharply during the recent financial crisis. The larger part of this increase was due to a dramatic rise – five fold as measured by variance – in idiosyncratic risk. We find that this pattern repeats itself during each major economic reversal going back 85 years. Because idiosyncratic risk is what is involved, this increase cannot be explained by changes in predictions concerning the future course of the economy as a whole.

Our first goal is to explain why difficult economic times, which are defined in terms of market wide phenomena, make the future ...


An Institutionalization Effect: The Impact Of Mental Hospitalization And Imprisonment On Homicide In The United States, 1934-2001, Bernard E. Harcourt Jan 2011

An Institutionalization Effect: The Impact Of Mental Hospitalization And Imprisonment On Homicide In The United States, 1934-2001, Bernard E. Harcourt

Previous research suggests that mass incarceration in the United States may have contributed to lower rates of violent crime since the 1990s but, surprisingly, finds no evidence of an effect of imprisonment on violent crime prior to 1991. This raises what Steven Levitt has called “a real puzzle.” This study offers the solution to the puzzle: the error in all prior studies is that they focus exclusively on rates of imprisonment, rather than using a measure that combines institutionalization in both prisons and mental hospitals. Using state-level panel-data regressions over the 68-year period from 1934 to 2001 and controlling for ...
