We examine how universal service provisions and price restrictions across markets impact strategic entry and pricing. We develop a simple multi-market model with an oligopolistic (profitable) urban market and entry auctions for (unprofitable) rural service. Cross-market price restrictions induce a firm operating in both markets to become a ‘softer’ competitor, thus placing the firm at a strateg...

Pre-tax car prices are particularly low in EU countries with high registration taxes but no car production, meaning that the tax is equivalent to an import tariff and induces international price discrimination. The paper develops a theorectical model to analyse the European Commission's policy of facilitating arbitrage and thereby reducing car price differences. The effects on prices, quantitie...

 As the number of independent countries increases and their economies become more integrated, we would expect to observe more multi-country currency :::union:::s. This paper explores the pros and cons for different countries to adopt as an anchor the US Dollar, the Euro or the Yen. In addition, it addresses the question of how co-movement of outputs and prices would respond to the formation of ...

Food commodity price fluctuations have an important impact on poverty and food insecurity across the world. Conventional models have not provided a complete picture of recent price spikes in agricultural commodity markets, while there is an urgent need for appropriate policy responses. Perhaps new approaches are needed in order to better understand international spill-overs, the feedback betwee...

We consider the interaction between an incumbent firm and a potential entrant, and examine how this interaction is affected by demand fluctuations. Our model gives rise to procyclical entry, prices, and price-cost margins, although the average price in the market can be countercyclical if the entrant is a first mover, and capacity utilization can be either proor countercyclical if the incumbent...

We provide a model for a futures clearinghouse to use for setting optimal levels of clearing margin, capital and price limits, which minimizes the costs to clearing firms and simultaneously protects the clearinghouse from default by clearing firms. We show how to estimate the capital requirement, which supports the clearinghouse s residual default risk that is not covered by the clearing margin...

This paper analyses the impact of a move from fractional to decimal pricing in the UK Long Gilt futures market. The reduced tick size following decimalisation leads to an increase in price clustering. The bid-ask spread, measured in ticks, increases following the tick size reduction. However, due to a reduced tick value, the monetary value of the spread declines. There is a substantial reductio...

We resume the search for a collusive focal-point effect of price ceilings in laboratory markets. We argue that market conditions in previous studies were unfavorable for collusion which may have been responsible for not finding such a focal-point effect. Our design aims at maximizing the likelihood of a focal-point effect. Nevertheless, our results again fail to support the focalpoint hypothesi...

How does commodity price volatility affect the welfare of rural households in developing countries, for whom hedging and consumption smoothing are often difficult? And when governments choose to intervene in order to stabilize commodity prices, as they often do, who gains the most? This paper develops an analytical framework and an empirical strategy to answer those questions, along with illust...

We experimentally explore how investor decision horizons influence the formation of stock prices. We find that in long-horizon sessions, where investors collect dividends till maturity, prices converge to the fundamental levels derived from dividends through backward induction. In short-horizon sessions, where investors exit the market by receiving the price (not dividends), price levels and pa...
