"The Relationship Between Public and Private Investment"

The relationship between government spending and aggregates such as output, employment, and prices has been the subject of many theoretical and empirical studies. Recently, however, interest has shifted to government spending on the provision of public capital (measured as fixed, nonresidential government capital) and various indicators of economic performance. Hence, government spending is now recognized to extend beyond the traditional view of strictly purchasing goods and services: The provision of public infrastructure has become an integral component. Erenburg finds that empirical estimates from the short-run, first-difference model indicate that each additional one percentage point increase in public infrastructure and government investment spending is associated with an approximate three-fifths of a percentage point increase in private of a percentage point increase in private sector equipment were obtained by using the Stock-Watson method for testing for long-run relationships when variables are integrated of higher order, including different orders. These estimates indicate an increase of approximately two-fifths of a percentage point in private equipment investment per year. Projections reveal that if the rate of growth of public capital stock had continued from 1966 through 1987 at the 1947-1965 average annual growth rate (instead of decreasing), the growth rate of private sector equipment investment would have been between 4 to 6 percentage points above the actual rate of growth. In addition to the impact on economic growth, Aschauer (1989) and Erenburg (1993) find a positive correlation between the public provision of infrastructure and private investment. As private investment activity enhances future growth of real income, these statistical results confirm that public policy has permanent effects on real output. The empirical results confirm that public policy has permanent effects on real output. The empirical results indicate that private sector equipment investment is inversely related to government investment spending and directly related to the existing public capital stock. Also, private equipment investment is much more sensitive to public provision of capital than either structures investment. These findings suggest that public infrastructure has an overall stimulative effect on private investment activity in the United States: In essence, these results verify Aschauer's, while addressing concerns of spurious correlation.

"Linking Public Capital to Economic Performance, Public Capital: The Missing Link Between Investment and Economic Growth "

Following up on findings by J. Bradford DeLong and Lawrence Summers that a robust statistical relationship exists between productivity and private sector investment in plant and equipment, Erenburg explores whether there is also a connection between economic growth and public spending. She argues that public investment in infrastructure stimulates private sector investment in plant and equipment. By providing empirical proof that public and private investment are complements in production, Erenburg supplies the missing link that explicitly ties public infrastructure to economic growth.

Climate change adaptation: where does global health fit into the agenda?

The aim of this paper is to highlight the opportunities to improve health and reduce health inequities via the new and additional funding that is available for climate change adaptation activities.Human-induced climate change will affect the lives of most populations in the next decade and beyond. It will have greatest, and generally earliest, impact on the poorest and most disadvantaged populations on the planet. Changes in climatic conditions and increases in weather variability affect human wellbeing, safety, health and survival in many ways. Some impacts are direct-acting and immediate, such as impaired food yields and storm surges. Other health effects are less immediate and typically occur via more complex causal pathways that involve a range of underlying social conditions and sectors such as water and sanitation, agriculture and urban planning. Climate change adaptation is receiving much attention given the inevitability of climate change and its effects, particularly in developing contexts, where the effects of climate change will be experienced most strongly and the response mechanisms are weakest. Financial support towards adaptation activities from various actors including the World Bank, the European Union and the United Nations is increasing substantially. With this new global impetus and funding for adaptation action come challenges such as the importance of developing adaptation activities on a sound understanding of baseline community needs and vulnerabilities, and how these may alter with changes in climate. The global health community is paying heed to the strengthening focus on adaptation, albeit in a slow and unstructured manner.&nbsp

Chair Support, Faculty Entrepreneurship, and the Teaching of Statistical Reasoning to Journalism Undergraduates in the United States

Statistical reasoning is not the same as doing calculations. Instead, it involves cognitive skills such as the ability to think critically and systematically with data, skills important for everyday news work and essential for the era of data journalism. Twin surveys of the chairs of undergraduate journalism programs in the United States, conducted 11 years apart, revealed that those who perceived benefits from statistical reasoning instruction were more likely to reward entrepreneurship (faculty attempts to integrate this instruction into their classes), but with slow gains over time in the fairly small number of such faculty. Being consistent with university goals in statistical reasoning instruction appeared to motivate chairs’ reward decisions in both waves. Increasingly, they took into account what they saw as the general value of statistical reasoning for their students and the competitive edge it could give them in the journalism job market. Perceived constraints to teaching this content had no apparent overall impact on reward decisions
