Quantal response equilibria

A quantal response specifies choice probabilities that are smooth, increasing functions of expected payoffs. A quantal response equilibrium has the property that the choice distributions match the belief distributions used to calculate expected payoffs. This stochastic generalization of the Nash equilibrium provides strong empirical restrictions that are generally consistent with...

Abuse of dominance and its effects on economic development

Rules on abuse of dominance are used to find a balance between three objectives: 1) ensuring enough competition between firms in order to force them to be efficient and to compete on merit, 2) allowing a certain degree of profitability so that companies have incentives to become more efficient, and 3) achieving an equal distribution of wealth and business opportunities among...

Governance failure and financial crisis in German football

The peculiar German football governance structure may be well suited to prevent integrity problems resulting from multiple club ownership or from ownership by "undesired'' persons or entities. However, this effect comes at a price. In the vacuum of power generated within large member associations, residual rights of control are de facto allocated to representatives who...

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...

New methods in quantitative ethnography: economic experiments and variation in the price of equality

We present a new method for quantitatively documenting concerns for economic fairness. In particular we focus on the method’s potential for identifying variation in
prosociality within and across societies. Specifically, we conducted multiple dictator games per player in two small-scale societies. Each game presented the decision maker with a choice between an equitable and an...

On the Optimal Timing of Capital Taxes

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...

Finite-Order Beliefs and Welfare-Enhancing Instruments in the Centipede Game

This paper investigates the effectiveness of two instruments designed to defer termination in the centipede game: an insurance against termination by the opponent, and an option to offer the opponent a bonus for not terminating the game. The rational prediction in both cases is passing until close to the end. Empirically, however, only the bonus option is used by the subjects. The...

This paper is a first attempt at disentangling the effects of financial integration on the two main determinants of economic performance: productivity (TFP)nand investments. I provide empirical evidence from a...

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...

Distribution and use of knowledge under the “Laws of the web”

Empirical evidence shows that the perception of information is strongly concentrated in those environments in which a mass of producers and users of knowledge interact through a distribution medium. This paper considers the consequences of this fact for economic equilibrium analysis. In particular, it examines how the ranking schemes applied by the distribution technology affect the...
