We study the optimal taxation of risk-free and excess capital income with heterogeneous rates of return, alongside an … optimal nonlinear earnings tax. Households can hold three assets: one risk-free, one risky but diversifiable, and one a … private investment with idiosyncratic risk whose expected return differs among households. Contrary to expectations, the …

construction of reliablesemi-parametric estimates of the risk associated with extreme pricemovements. Our approach is based on semi …

Empirical measures of world consumption growth risk have failed to rationalize the cross-section of country equity … returns. We propose a new factor, termed "the global consumption factor", to explain the patterns in risk premiums on … from 47 developed and emerging market countries over a four-decade period. Our risk factor reflects changes in the cross …

considerations, and minimum fines. Bankruptcy considerations limit maximum fines, ensure abnormal cartel profits and impose a … lower price by making it more attractive than collusion on higher prices. For a range of low cartel prices, the fine is set … to the legal mi nimum. Raising minimum fines will enable the cartel to raise its price and is better avoided. Our …

actual cartel effects. In this paper, we show that misdating cartel effects leads to a (weak) overestimation of but … antitrust damage estimation based on predicted cartel prices can have either sign. We extend the before-during-and-after method … with an empirical cartel dating procedure that uses multiple structural break tests to determine the actual begin and end …

We analyze how leniency affects cartel pricing in an infinitely-repeated oligopoly model where the fine rates are … we focus on the worst possible outcome. We investigate the maximal cartel price, the largest price for which the … conditions for sustainability hold. We analyze how the maximal cartel price supported by different cartel strategies adjusts in …
