Research background: Many people in Japan and other countries believe that national finances will not stand still and will go bankrupt if deficits continue at present level. It is like a religion. In this paper, however, we prove that this religion is wrong by using a simple mathematical model....

Does it pay to invest in green companies? In countries where a market for carbon is functioning, such as those within the European Union, our findings suggest that it should be beneficial. Using a sample of green and brown European firms, we initially demonstrate that green companies have...

Questions about market power have become salient in macroeconomics. We consider the role of institutional structures in addressing these within a dynamic general equilibrium framework. Standard models account for monopoly profits as a lump-sum transfer to the representative agent. We label this...

Purpose of the article: A correct understanding of mechanisms governing the market is crucial for proper functioning of the labour market. The market structure phenomenon, so far most frequently described in the imperfect competition theory as a bilateral monopoly, occupies a unique position in...

We develop a structural framework that allows us to quantify the evolution of aggregate bilateral trade costs and markups over time. With minimal assumptions, we can disentangle aggregate markup and trade cost changes from observed changes in trade flows. We apply our method to trade data...

Due to markup distortions, in international trade models with monopolistic competition and heterogeneous firms the market equilibrium is inefficient unless demand exhibits constant elasticity of substitution. When it does not, global welfare maximization generally requires policy intervention...

Based on the sufficient statistics approach developed by Huang and Ottaviano (2024), we show how the state of technology of European industries relative to the rest of the world can be empirically assessed in a way that is simple in terms of computation, parsimonious in terms of data...

This article examines George Christopher Archibald's contributions to monopolistic competition theory, which he approached from multiple perspectives throughout his career. In the 1950s, he critiqued this theory for its vague definitions and for prompting several economists to abandon profit...

In this paper, we explore how heterogeneous firms decide on vertical and horizontal qualities of their products. We show that if increasing the product qualities appears to be relatively costly, more productive firms choose higher vertical quality but lower horizontal quality. We also document...

Mainstream monopoly theory and as related to anti-trust measures evaluates the concentration of an industry to determine if a firm has monopoly power within an industry (Cabral 2000 [2017]). If a firm is dominant within an industry, then it is presumed that consumer surplus is being reduced at...

This paper analyzes the implications of the gradual rise in bank concentration since the 1990s for the transmission of monetary policy. I use branch-level data on deposit and loan rates to evaluate the monetary policy pass-through conditional on the level of local bank concentration and bank...

This study explores the optimal taxation of participation within a monopolistically competitive product market that exhibits increasing markups. Individual labor supply responds along both intensive and extensive margins. The government simultaneously optimizes a non-linear Mirrleesian income...

We provide a survey of the main mechanisms of market selection used in economics. We gather them in three theoretical paradigms (rational equilibrium, Simonesque and evolutionary), that we try to reconcile in terms of underlying laws of selection. We show that the three paradigms have been...
