Do Median Grades Vary Across Departments?

[Excerpt] This study will analyze if median course grades systematically vary across departments in Cornell University’s College of Arts and Sciences. After briefly discussing other factors that might be expected to influence median grades and thus must be included in the analyses, I present my empirical findings. A final section discusses the implications of my findings

Evaluating Characteristic Functions of Character Sheaves at Unipotent Elements

Assume $\mathbf{G}$ is a connected reductive algebraic group defined over an algebraic closure $\mathbb{K} = \overline{\mathbb{F}}_p$ of the finite field of prime order $p>0$. Furthermore, assume that $F : \mathbf{G} \to \mathbf{G}$ is a Frobenius endomorphism of $\mathbf{G}$. In this article we give a formula for the value of any $F$-stable character sheaf of $\mathbf{G}$ at a unipotent element. This formula is expressed in terms of class functions of $\mathbf{G}^F$ which are supported on a single unipotent class of $\mathbf{G}$. In general these functions are not determined, however we give an expression for these functions under the assumption that $Z(\mathbf{G})$ is connected, $\mathbf{G}/Z(\mathbf{G})$ is simple and $p$ is a good prime for $\mathbf{G}$. In this case our formula is completely explicit.Comment: 29 pages. Parts of this article first appeared in arXiv:1306.5882. This is an expanded and generalised of version of what appears there.

The curse of cash, by Kenneth S. Rogoff (Princeton University Press, Princeton, NJ, 2016)

The world is drowning in cash—and it’s making us poorer and less safe. In The Curse of Cash, Kenneth Rogoff, one of the world’s leading economists, makes a persuasive and fascinating case for an idea that until recently would have seemed outlandish: getting rid of most paper money. Even as people in advanced economies are using less paper money, there is more cash in circulation—a record $1.4 trillion in U.S. dollars alone, or$4,200 for every American, mostly in $100 bills. And the United States is hardly exceptional. So what is all that cash being used for? The answer is simple: a large part is feeding tax evasion, corruption, terrorism, the drug trade, human trafficking, and the rest of a massive global underground economy. As Rogoff shows, paper money can also cripple monetary policy. In the aftermath of the recent financial crisis, central banks have been unable to stimulate growth and inflation by cutting interest rates significantly below zero for fear that it would drive investors to abandon treasury bills and stockpile cash. This constraint has paralyzed monetary policy in virtually every advanced economy, and is likely to be a recurring problem in the future. The Curse of Cash offers a plan for phasing out most paper money—while leaving small-denomination bills and coins in circulation indefinitely—and addresses the issues the transition will pose, ranging from fears about privacy and price stability to the need to provide subsidized debit cards for the poor. While phasing out the bulk of paper money will hardly solve the world’s problems, it would be a significant step toward addressing a surprising number of very big ones. Provocative, engaging, and backed by compelling original arguments and evidence, The Curse of Cash is certain to spark widespread debate.Accepted manuscrip

John Maynard Keynes, man or myth? The incident of the Spanish pesetas

John Maynard Keynes was and still is one of the world’s most famous economists. One of the most fascinating stories about Keynes appeared in his obituary in the 1946 Proceedings of the British Academy. The story stated that during World War I with minimal financial resources Keynes broke the Spanish-British foreign exchange market, a manipulation that is illegal today. This research investigates if the story is myth or truth. Archival materials suggest Keynes did manipulate this foreign exchange market in April of 1918 and he potentially earned £8 million on his trades.First author draf
