Many economic models use a continuum of negligible agents to avoid considering one person's effect on aggregate characteristics of the economy. Along with a continuum of agents, these models often incorporate a sequence of independent shocks and random matchings. Despite frequent use of such...

While the average change in house prices is related to changes in fundamentals or perhaps market-wide bubbles, not all houses in a market appreciate at the same rate. The primary focus of our study is to investigate the reasons for these variations in price changes among houses within a market....

A popular argument about economic policy under uncertainty states that decentralisation offers the possibility to learn from local or regional policy experiments. Often, an analogy between market competition as a discovery procedure and political competition is used to corroborate this argument....

We develop different spatial search models in which a land market is embedded into a standard search matching framework. The link between the land and the labour market is realized through the average search intensity of unemployed workers. We first develop a simple model where search intensity...

Why are some cities specialized and others diversified? What are the advantages and disadvantages of urban specialization and diversity? To what extent does the structure of cities, and the activities of firms and people in them, change over time? How does the sectoral composition of cities...

We study the evolution of prices set by duopolists who are uncertain about the perceived degree of product differentiation. Customers sometimes view the products as close substitutes, sometimes as highly differentiated. As the informativeness of the quantities sold increases with the price...

We study a game of strategic experimentation with two-armed bandits where the risky arm distributes lump-sum payoffs according to a Poisson process. Its intensity is either high or low, and unknown to the players. We consider Markov perfect equilibria with beliefs as the state variable. As the...

In this paper we analyse the role of asymmetric information between firms and consumers about market conditions. In standard models of oligopoly informational advantages of firms over customers do not play a role because all prices are observable. When customers are unable to observe all...

A central tenet of inflation targeting is that establishing and maintaining well-anchored inflation expectations are essential. In this paper, we reexamine the role of key elements of the inflation targeting framework towards this end, in the context of an economy where economic agents have an...

We develop a search matching model in which blacks and whites are totally identical, except for the fact that they use different transport modes. We find that whites, who use faster transport modes (i.e. cars) than blacks (who use public transport), do search more intensively and extensively,...
