Other-regarding preferences in a non-human primate: common marmosets provision food altruistically

Human cooperation is unparalleled in the animal world and rests on an altruistic concern for the welfare of genetically unrelated strangers. The evolutionary roots of human altruism, however, remain poorly understood. Recent evidence suggests a discontinuity between humans and other primates because individual chimpanzees do not spontaneously
provide food to other group members...

For many kinds of capital, depreciation rates change systematically with the age of the capital. Consider an example that captures essential aspects of human capital, both regarding its accumulation and its depreciation: a worker obtains knowledge in period 0, then uses this knowledge innproduction in periods 1 and 2, and thereafter retires. Here, depreciation accelerates: it occurs...

Monopolistic Screening under Learning By Doing

This paper investigates the design of incentives in a dynamic adverse selection framework when agents’ production technologies display learning effects and agents’ rate of learning is private knowledge. In a simple two-period model with full commitment available to the principal, we show that whether learning effects are over- or under-exploited crucially depends on whether learning...

Nominal and Real Interest Rates during an Optimal Disinflation in New Keynesian Models

Central bankers' conventional wisdom suggests that nominal interest rates should be raised to implement a lower inflation target. In contrast, I show that the standard New Keynesian monetary model predicts that nominal interest rates should bendecreased to attain this goal. Real interest rates, however, are virtually unchanged. These results also hold in recent vintages of New...

A Monetary Model with Strong Liquidity Effects

This paper studies the joint business cycle dynamics of innation, money growth, nominal and real interest rates and the velocity of money. I extend and estimate a standard cash and credit monetary model by adding idiosyncratic preference shocksnto cash consumption as well as a banking sector. The estimated model accounts very well for the business cycle data, a finding that standard...

Optimal Ramsey Tax Cycles

This paper asks whether tax cycles can represent the optimal policy in a modelnwithout any extrinsic uncertainty. I show, in an economy without capital and where labor is the only choicenvariable (a Lucas-Stokey economy), that a large class of preferences exists, where cycles are optimal, as well as a large class where they are not. The larger government expenditures are, the larger...

Temporary fluctuations of the U.S. consumption-wealth ratio, cay, predict excess returns onninternational stock markets at the business cycle frequency. This finding is the reflection of a common, temporary component in national stock markets. Exposure to this common component explains up to 60 percent of the covariation among long-horizon returns on the G7nstock markets for the time...
