Carbon prices in the EU emissions trading system (EU ETS) are a key instrument driving Europe’s decarbonization. Between 2017 and 2021, they surged tenfold, exceeding 80 €/tCO2 and reshaping investment decisions across the electricity and industry sectors. What has driven this increase is an...

To provide a more flexible workhorse model of temporary price reductions or `sales', this paper presents a substantially generalized `clearinghouse' sales framework. Our framework permits multiple dimensions of firm heterogeneity, and views firms as competing directly in utility rather than...

Excess capacity is viewed as a distinctive feature and an essential inefficiency of monopolistic competition as the large-group case of imperfect competition. Using a simple geometrical approach and studying the demand and cost curves faced by the individual firm, we find that there is little...

We augment an otherwise standard business cycle model with a richer government sector, and add monopolistic competition in the product market, and rigid prices, as well as rigid wages a la Calvo (1983) in the labor market. This specification with the nominal wage rigidity, when calibrated to...

In recent years, the increasing awarding of patents has captured the attention of scholars operating in different fields. The economic literature has studied the causes of this proliferation; we propose an entry game focusing on one of the consequences, showing how an incumbent may create a...

We investigate the role tacit collusion plays in Asymmetric Price Transmission (APT), the tendency of prices to respond more rapidly to positive than to negative cost shocks. Using a laboratory experiment that isolates the effects of tacit collusion, we observe APT pricing behavior in markets...

This paper reconciles the Cournot and Bertrand Models of oligopolistic competition, highlighting its weaknesses and giving an opinion thereafter. The pertinent question in this paper is why Cournot (1838) ignored the price and Bertrand (1883) ignored the quantity? From the review, the main...

Determinants of economic growth in Ghana are analysed using restricted vector autoregressive (VAR) model for the period 1975-2013. The empirical results reveal that GDP per capita in long-run is driven by export, oil and mineral rents while government consumption retard economic growth....

This paper investigates for the presence of a New Keynesian Phillips (NKPC) curve in Hungary in the period 1981:3-2006:2, following the methodology proposed by Gali and Gertler (1999). They claim that a potential source of inflation may be the sluggish adjustment of real marginal costs to...

The paper analyzes Australian exchange rate and its determinants by providing an insight into the economic and non-economic factors. By drawing a comparison between quarterly and annual data over the period of 1975 to 2012, it is suggested that Australia’s trade components and macroeconomic...
