In this paper we use unit roots/cointegration analysis and time-varying parameters procedures to test for a common growth path in the ex-communist block, both pre- and post-reform. We test whether there has been convergence within the block and between the block as a group and the West....

Price volatility, reflecting the ability to absorb exogenous supply- or demand shocks, is an important dimension of market performance. In this paper we present a model to study the factors determining the price volatility of markets of basic foodstuffs in pre industrial societies. This model is...

Previous research shows that firms shroud high add-on prices in competitive markets with naive consumers leading to inefficiency. We analyze the effects of regulatory intervention via educating naive consumers on equilibrium prices and welfare. Our model allows firms to shroud, unshroud, or...

The Paper analyses the funding of an infrastructure project (high speed train line, platform, tunnel, harbor, regional airport, fibre-to-the-home network, etc.) in a situation in which an incumbent operator has private information about market profitability (demand, cost) and the infrastructure...

We develop a general theoretical framework of trade on a platform on which buyers and sellers interact. The platform may be owned by a single large, or many small independent or vertically integrated intermediaries. There also may be free entry into the market for platform slots, or platform...

This paper examines Norwegian gasoline pump prices using daily station-specific observations from March 2003 to March 2006. Whereas studies that have analyzed similar price cycles in other countries find support for the Edgeworth cycle theory (Maskin and Tirole, 1988), we demonstrate that...

We develop a multi-period model of strategic trading in an asset market where traders are uncertain about market liquidity. In our model, informed traders strategically trade against competitive market makers to exploit their short-lived private information. Unlike market makers, informed...

New Keynesian literature assumes symmetric industrial structure when analysing explanations of monetary non-neutrality. We analyse the impact of modifying this assumption by allowing for a mixed industrial structure; some industries are characterized by monopolistic competition, and others by...

We analyze whether and how the fact that products are not sold on open or public platforms but on competing for-profit platforms affects sellers’ investment incentives. Investments in cost reduction, quality, or marketing measures are here the joint and coordinated efforts by sellers. We show...

In many intermediate goods markets buyers and sellers both have market power. Contracts are usually long-term and negotiated bilaterally, codifying many elements in addition to price. We model such bilateral oligopolies as a set of simultaneous Rubinstein-Ståhl bargainings between pairs of...
