This paper reports experimental evidence on behaviour in an Ultimatum Game where responders have low structural information and feedback so that they have to learn the nature of the game during repeated play. The results lend support to the view that certain learning conditions are less...

This paper proposes a stylized model that reconciles several seemingly conflicting findings on financial security returns and option prices. The model is based on a pure jump Levy process, wherein the jump arrival rate obeys a power law dampened by an exponential function. The model allows for...

We document a surprising pattern in market prices of S&P 500 index options. When implied volatilities are graphed against a standard measure of moneyness, the implied volatility smirk does not flatten out as maturity increases up to the observable horizon of two years. This behavior contrasts...

This paper develops a model of pricing and advertising in a matching environment with capacity constrained sellers. Sellers' expenditure on directly informative advertising attracts consumers only probabilistically. Consumers who happen to observe advertisements randomize over the advertised...

When potential shareholders cannot observe the business conditions of the firms, the latter desiring to acquire capital by an IPO and operating under less favourable business conditions have a strong incentive to appear more successful.

This paper studies the international portfolio flows of US investors to examine the information structure of international equity markets. We use an empirical model of portfolio flows with both public and private information to extract measures of trades due to private information. We find that...

One of the most striking results in experimental economics is the ease with which market bubbles form in a laboratory setting and the difficulty of preventing them. This article re-examines bubble experiments in light of the results of an earlier series of market experiments that examine how...

This is a short literature overview. (1) The literature demonstrates no coherent view on the nature of economic exchange and, in particular, provides no conventionally accepted, fully satisfactory explanation of the real effects of money. Recent developments in macroeconomics suggest a role for...

In a world with private information about the quality of technology we find that there are situations where relatively more technologically superior firm will license its technology but relatively less technologically superior firm will not license its technology. This finding is opposite to the...

Participants in a market, buyers and sellers, may need the service of an intermediary who will put them into contact and give them information about their potential trading partner. The intermediary chooses what price it will charge to each side to have access to its service. It also chooses...
