The newest outcome of bilateral monopoly (BM) of lignite opencast mine & power plant analysis have been discussed. The determinism of optimal solution maximising joint profits not only in quantity of lignite - the size and shape of the ultimate pit (characteristic to classical solution) but also...

After some decades of relative oblivion, the interest in the optimality properties of monopolistic competition has recently re-emerged due to the availability of an appropriate and parsimonious framework to deal with firm heterogeneity. Within this framework we show that non-separable utility,...

We derive a dynamic structural model based on a dynamic supergame model and measure market power for the Dallas-Forth Worth milk market in the U.S. In particular, we analyze the cyclical behavior of firm conduct and evaluate bias in static market-power measures in a unified manner by deriving...

Kutlu (2009, “Price discrimination in Stackelberg competitionâ€, Journal of Industrial Economics) shows that the Stackelberg leader sells to the highest value consumers and only the Stackelberg follower practises price discrimination. We show that this result is not robust if the...

This paper studies discounting in mortgage markets. Using transaction-level data on Canadian mortgages, we document that over time there’s been an increase in the average discount, along with substantial dispersion. The standard explanation for dispersion in credit markets is that lenders...

Consumers often incur costs when switching from one product to another. Recently there has been renewed debate within the literature about whether these switching costs lead to higher prices. We build a theoretical model of dynamic competition and solve it analytically for a wide range of...

Assuming that consumers value both the absolute and relative quality of play, I compare the choice of ticket prices, team qualities, and number of games played in a noncooperative outcome versus that chosen by a social planner. I find that the nature of consumer preferences regarding the quality...

Wer nur an die Marktwirtschaft glaubt, ist abergläubisch, stellte der katholische Theologe Hans Küng vor einigen Jahren in einem Beitrag „Ökonomie und Theologie“ für Studenten der Wirtschaftswissenschaften fest. Soziale Marktwirtschaft, so ließe sich fortfahren, schützt vor diesem...

Despite the pervasive phenomenon of scale economies the majority of firms hasalways been small firms. The emergence of small firms as a means of economic development on both sides of the Atlantic has been one of the major new topics of economic policy since the 1980s. This has drawn renewed...
