This paper explores the economic implications of different contract durations in markets for on-line (primary and secondary) reserve capacity in Germany with the crucial feature of separate markets for spot energy and reserve capacity provision. The analysis is based on an equilibrium model...

This paper develops a framework to systematically study how changes in market conditions affect the equilibrium inequality between heterogeneous agents. By stating our setting as a "competition for market shares", we can derive inequality predictions for vastly different competition models. This...

This paper examines the efficiency of stable matchings in a framework of general equilibrium. In my model of a large private competitive economy, firms and managers form partnerships in an upstream labor (matching) market and then firm-manager pairs compete in a downstream goods market. I find...

We present a loanable funds framework that provides students with a quick and clear under­standing of interest rate determination. Within the presented loanable funds framework we can (i) clarify the role of information for the emergence of liquidity effects of money, (ii) clarify long-term...

How much information should brokers supply on a website? The Internet allows brokers to reduce the cost of providing information to potential buyers. However, brokers may risk disintermediation if they provide too much information. This paper presents a model of a broker's choice of how much...

We analyze the interplay between product market prices and firm boundary decisions. Enterprises are heterogeneous with respect to their productivities and each enterprise chooses between two ownership structures--centralized ownership (integration) performs well in coordinating managerial...

The current dispute between the NFL Network and cable operators over carriage arrangements is a sign the market is working rather than failing. Proposed state legislation mandating arbitration for these disputes negates the programming distributor's ability to negotiate price, terms and...

While mainstream economics assumes that firms are always on the production frontier, there is an evolutionary interpretation of competition according to which firms have different degrees of what Leibenstein (1964) called quot;X-efficiency,quot; and competition selects for higher X-efficiency....

We show that intermediate goods can be sourced to firms on the quot;outsidequot; (that do not compete in the final product market), even when there are no economies of scale or cost advantages for these firms. What drives the phenomenon is that quot;insidequot; firms, by accepting such orders,...

Making trade work for all and harnessing popular support for openness to trade depends on consumers benefitting from lower prices and broader product variety. The present study reveals that those benefits depend on competition in services markets, in particular in telecommunication. These...
