The carry trade strategy involves selling forward currencies that are at a forward premium and buying forward currencies that are at a forward discount. We compare the payoffs to the carry trade applied to two different portfolios. The first portfolio consists exclusively of developed country...

any studies have replicated the finding that the forward rate is a biased predictor of the future change in the spot exchange rate. Usually the forward discount actually points in the wrong direction. But virtually all those studies apply to advanced economies and major currencies. We apply the...

Currencies that are at a forward premium tend to depreciate. This 'forward-premium puzzle' represents an egregious deviation from uncovered interest parity. We document the properties of returns to currency speculation strategies that exploit this anomaly. We show that these strategies yield...

The forward premium anomaly is one of the most robust puzzles in financial economics. We recast the underlying parity relation in terms of cross-country differences between forward interest rates rather than spot interest rates with dramatic results. These forward interest rate differentials...

We present a novel empirical benchmark for analyzing credit risk using "pseudo firms" that purchase traded assets financed with equity and zero-coupon bonds. By no-arbitrage, pseudo bonds are equivalent to Treasuries minus put options on pseudo-firm assets. Empirically, like corporate spreads,...

This paper explores the trade-off between incentive effects and administrative costs associated with the implementation of various environmental tax instruments, with special reference to carbon taxes. In a simple model, we show under what conditions it is optimal to use input rather than...

The extent of social expenditures in the U.S. and the Nordic Countries is compared in the early 1900s and again in the early 2000s. The common view that America spends much less on social welfare than the Nordic countries does not survive closer inspection when we consider the differences in the...

In the late 1980s and early 1990s, concern over dioxin in both paper products and wastewater led to the development of techniques that reduced the use of chlorine in the pulp industry. Both regulatory and consumer pressure motivated this change. We use patent data to examine the evolution of two...
