Freeman Dyson of the Institute for Advanced Study in Princeton talks with EconTalk host Russ Roberts about science, his career, and the future. Dyson argues for the importance of what he calls heresy--challenging the scientific dogmas of the day. Dyson argues that our knowledge of climate science is incomplete and that too many scientists treat it as if it were totally understood. He reflects on his childhood and earlier work, particularly in the area of space travel. And he says that biology is the science today with the most exciting developments.

Author and syndicated columnist George Will talks with EconTalk host Russ Roberts about the state of the country, the nature of politics, and at the end, a little about baseball. The conversation begins with Will discussing his career and how someone with a Ph.D. from Princeton got involved in politics and then writing. Will then discusses the current political environment and how little some things have changed in politics. Other topics include the future of journalism and Will's predictions for how the Chicago Cubs will fare this season (4th place).

Daron Acemoglu of MIT talks with EconTalk host Russ Roberts about the role income inequality may have played in creating the financial crisis. Raghuram Rajan in his book, Fault Lines, argues that growing income inequality in the last part of the 20th century created a political demand for redistribution and various policy changes. This in turn created the push for higher home ownership rates and led to the distortions of the housing market that in turn led to excessive risk-taking in the financial market. Acemoglu suggests a simpler story where the financial sector through its political influence distorted the rules of the game, benefiting executives in the industry, which in turn led to outsized rewards and ultimate instability in the financial industry. The conversation discusses ways of distinguishing between these two arguments and what might be done to change the incentives of politicians.

Tyler Cowen of George Mason University and author of the e-book The Great Stagnation talks with EconTalk host Russ Roberts about the ideas in the book. Cowen argues that in the last four decades, the growth in prosperity for the average family has slowed dramatically in the United States relative to earlier decades and time periods. Cowen argues that this is the result of a natural slowing in innovation and that we expect too much growth relative to what is possible. Cowen expects improvements in the rate of growth in the future when new areas of research yield high returns. The conversation includes a discussion of the implications of Cowen's thesis for politics and public policy.

Arnold Kling of EconLog talks with EconTalk host Russ Roberts about a new paradigm for thinking about macroeconomics and the labor market. Kling calls it PSST--patterns of sustainable specialization and trade. Kling rejects the Keynesian approach that emphasizes shortfalls in aggregate demand arguing that the aggregate demand approach masks the underlying complexity of the recalculations that periodically take place in a dynamic economy. Instead, Kling invokes the mutual exploration between entrepreneurs and workers for profitable opportunities that pay well using the workers' skills. This exploration takes time, involves trial and error, and can have false starts because businesses sometimes fail or employees are difficult to find or match with employment opportunities. Kling applies these ideas to the current crisis to explain why labor market recovery is so sluggish and what might policies might improve matters.

Investigative journalist Brian Deer talks with EconTalk host Russ Roberts about Deer's seven years of reporting and legal issues
surrounding the 1998 article in The Lancet claiming that the MMR vaccine causes autism and bowel problems. Deer's dogged pursuit of the truth led to the discovery that the 1998 article was fraudulent and that the lead author had hidden payments he received from lawyers to finance the original study. In this podcast, Deer describes how he uncovered the truth and the legal consequences that followed. The conversation closes with a discussion of the elusiveness of truth in science and medicine.

Steve Fazzari of Washington University in St. Louis talks with EconTalk host Russ Roberts about the economics of Keynesian stimulus. They discuss the stimulus package passed in February 2009 and whether it improved the economy and created jobs. How should claims about its impact be evaluated? What can we know as economists about causal relationships in a complex world? The conversation includes a discussion of the underlying logic of Keynesian stimulus and the effect of the financial crisis on economic research and teaching.

Don Boudreaux of George Mason University talks with EconTalk host Russ Roberts on some of the common misunderstandings people have about prices, money, inflation and deflation. They discuss what is harmful about inflation and deflation, the importance of expectations and the implications for interest rates and financial institutions.

Bruce Caldwell of Duke University and the General Editor of the Collected Works of F. A. Hayek, talks with EconTalk host Russ Roberts about Hayek, his life, his ideas, his books, and articles. The conversation covers Hayek's intellectual encounters with Keynes, Hayek's role in the socialist calculation debate, Hayek's key ideas, and a discussion of which of Hayek's works are most accessible.

Robin Hanson of GMU talks with EconTalk host Russ Roberts about the idea of a technological singularity--a sudden, large increase in the rate of growth due to technological change. Hanson argues that it is plausible that a change in technology could lead to world output doubling every two weeks rather than every 15 years, as it does currently. Hanson suggests a likely route to such a change is to port the human brain into a computer-based emulation. Such a breakthrough in artificial intelligence would lead to an extraordinary increase in productivity creating enormous wealth and radically changing the returns to capital and labor. The conversation looks at the feasibility of the process and the intuition behind the conclusions. Hanson argues for the virtues of such a world.
