The paper studies equilibrium pricing in a product market for an indivisible good where buyers search for sellers. Buyers search sequentially for sellers, but do not meet every sellers with the same probability. Specifically, a fraction of the buyers’ meetings lead to one particular large seller, while the remaining meetings lead to one of a continuum of small sellers. In this environment, the ...

We analyze a two-stage game where capacity constrained electricity generators first choose how much capacity they make available and then compete in a uniform price auction. We study how capacity withholding can be used strategically to enforce market power and how uniform auctions in the price game change the results of capacity constrained competition models. Our main finding is that the unif...

The trend toward increasing energy efficiency and variable renewable energy (VRE) production has implications for combined heat and power (CHP) plants, which operate in both the price-driven power market and the district heating (DH) sector. Since CHP will be important in VRE integration, we develop a complementarity model to analyze CHP producers’ roles in integrated markets. We use a Nordic c...

Accurate and effective electricity price forecasting is critical to market participants in order to make an appropriate risk management in competitive electricity markets. Market participants rely on price forecasts to decide on their bidding strategies, allocate assets and plan facility investments. However, due to its time variant behavior and non-linear and non-stationary nature, electricity...

Stock market is affected by news and information. If the stock market is not efficient, the reaction of stock price to news and information will place the stock market in overreaction and under-reaction states. Many models have been already presented by using different tools and techniques to forecast the stock market behavior. In this study, the reaction of stock price in the stock market was ...

anaging power generation assets is a complex and challenging task. From the perspective of a regulated utility, the objective is to satisfy its customers and minimise costs. The focus of other energy service companies operating in a deregulated market is on profit maximisation. Large power companies may hold many assets that include a variety of fossil-fuelled power plants such as coal, gas or ...

This paper provides a framework for the empirical analysis of negotiated-price markets in which buying is single-source. These markets pose a challenge for empirical work since, although buyers potentially negotiate with many sellers, data-sets typically include only accepted offers. Moreover, negotiated-price markets feature search frictions, since consumers incur a cost to gather quotes, and ...

This paper develops and tests implications of an oligopoly-pricing model. The model predicts that during a demand expansion the short run competitive price is a pure strategy Nash equilibrium, but in a recession firms set prices above the competitive price. Thus, price markups over the competitive price are countercyclical. Prices set during a recession are more variable than prices set in expa...

The rise to prominence of Wal-Mart and other big-box retailers has given new life to the debate about whether “buyer power” at intermediate links in a vertically related chain of industries is good or bad for consumers and hence whether it requires the attention of competition authorities. The term is rarely precisely defined, but as used by most commentators “buyer power” refers to the circums...
