Entering the Door

How do physical limitations affect the mind, and how can you overcome them? Imagine one day you wake up bound by physical limitations. What can you do? My research helps someone realize that having limitations isn’t the end of the world.I myself have restrictions, yet I am defying the odds.My art became integral to helping me overcome limitations; because of this, my thesis research educates others on the reality of living with limitations by helping them connect with their own struggles

Professional Learning Portfolios for Argumentation in School Science

This paper reports on the use of portfolios in a continuing professional development programme to advance teachers’ skills in their pedagogy of argumentation. The programme adopted a cyclical process of expert input- teacher practice- sharing practice, in order for professional learning to include reflective analysis of growing accomplishment. Accomplishment was initially defined according to previous research and development on the teaching of argumentation, but was redefined during the programme as teachers shared practice and discussed their achievements. Portfolios were used to help teachers apply their learning, collate evidence of their accomplishment and share reflective analysis of practice with other colleagues on the programme. The paper includes extracts of two teachers’ portfolios; these provide evidence of each teacher’s developing accomplishment in the teaching of argumentation. Portfolios are idiosyncratic and are constructed according to an individual teacher’s motivations, interpretations and situations. Teachers need structure and guidance in creating purposeful portfolios that enhance reflective practice

Europe on the Brink

Europe’s efforts to stabilize its finances are failing, and the region needs to prepare for widespread restructuring of sovereign and bank debt. Peter Boone and Simon Johnson argue that Europe’s financial system has relied on a policy of protecting creditors from default and has thus spread pervasive moral hazard—a presumption by creditors that they will not take losses on their loans to Greece and other ailing countries. The authors argue that this situation is no longer tenable and examine three possible scenarios for the coming months as the sovereign debt crisis evolves. Under the first scenario, the euro area would try to reassert its commitment to avoid defaults and inflation. This continuation of the moral hazard regime would require severe austerity for Greece and other countries on the periphery of the euro area. The second scenario involves elimination of the moral hazard regime. The euro area would admit that some sovereigns have too much debt. A series of debt restructurings would follow. The final scenario would be for policymakers to continue to contradict themselves by promising selective defaults or restructurings of some countries’ debts while maintaining that they can ensure the stability of the rest of the euro area. But the authors argue that it is an illusion to believe that selective restructuring would not introduce contagion. Such an approach would result in panic, massive capital flight, and disorderly defaults. The ensuing chaos would in turn lead to a negatively charged political atmosphere that would make consensus nearly impossible.

The European Crisis Deepens

Successive plans to restore confidence in the euro area have failed. A combination of misdiagnosis, lack of political will, and dysfunctional politics across 17 nations have all contributed to the failure so far to stem Europe's growing crisis. Proposals currently on the table also seem likely to fail. Boone and Johnson say the euro area faces two major problems: First, the introduction of sovereign credit risk has made nations and subsequently banks effectively insolvent unless they receive large-scale bailouts. Second, the ensuing credit crunch has exacerbated difficulties in the real economy, causing Europe's periphery to plunge into recession, thus increasing the financing needs of troubled nations well into the future. Five measures are needed to enable the euro area to survive: (1) an immediate program to deal with excessive sovereign debt, (2) far more aggressive plans to reduce budget deficits and make peripheral nations "hypercompetitive" in the near future, (3) supportive monetary policy from the European Central Bank, (4) the introduction of mechanisms that credibly achieve long-term fiscal sustainability, and (5) institutional change that reduces the scope for excessive leverage and consequent instability in the financial sector.

Disease and Development: The Effect of Life Expectancy on Economic Growth

What is the effect of increasing life expectancy on economic growth? To answer this question, we exploit the international epidemiological transition, the wave of international health innovations and improvements that began in the 1940s. We obtain estimates of mortality by disease before the 1940s from the League of Nations and national public health sources. Using these data, we construct an instrument for changes in life expectancy, referred to as predicted mortality, which is based on the pre-intervention distribution of mortality from various diseases around the world and dates of global interventions. We document that predicted mortality has a large and robust effect on changes in life expectancy starting in 1940, but no effect on changes in life expectancy before the interventions. The instrumented changes in life expectancy have a large effect on population; a 1% increase in life expectancy leads to an increase in population of about 1.5%. Life expectancy has a much smaller effect on total GDP both initially and over a 40-year horizon, however. Consequently, there is no evidence that the large exogenous increase in life expectancy led to a significant increase in per capita economic growth. These results confirm that global efforts to combat poor health conditions in less developed countries can be highly effective, but also shed doubt on claims that unfavorable health conditions are the root cause of the poverty of some nations.

Cronyism and Capital Controls: Evidence from Malaysia

The initial impact of the Asian financial crisis in Malaysia reduced the expected value of government subsidies to politically favored firms. Of the estimated $60 billion loss in market value for politically connected firms from July 1997 to August 1998, roughly 9$5 billion gain in market value for Mahathir-connected firms during September 1998, approximately 32% was due to the increase in the value of their connections. The evidence suggests Malaysian capital controls provided a screen behind which favored firms could be supported.
