This paper extends the standard model of optimum commodity taxation (Ramsey (1927) and Diamond-Mirrlees (1971)) to a competitive economy in which some markets are inefficient due to asymmetric information. As in most insurance markets, consumers impose varying costs on suppliers but …firms...

Based on product homogeneity and Cournot competition, a recurrent finding in the literature is that ad valorem taxation is welfare superior to unit taxation in noncompetitive markets. This paper first observes that with asymmetric costs inefficient firms are more likely to be inactive in...

In this paper we investigate a dynamic setting of environmental taxation, for which the government imposes a tax rate in order to internalize externalities caused by polluting firms. The basic model consists of the intertemporal maximization problem for an additively separable utility which is...

This paper examines the economic rationales and conditions for the emer - gence of multinational enterprises (MNEs). Promoting production efficiency is not sufficient to justify the emergence of an MNE. With taxes in the model, tax authorities heavily tax an MNE’s economic activities, in which...

Newspapers are two-sided platforms that sell their product both to readers and advertisers. Media firms in general, and newspapers in particular, are considered important providers of information, culture and language in most countries. Newspapers are therefore given preferential tax treatment....

This paper analyzes a class of two-stage Cournot games where firms are collusive in the first stage, and shows that oligopolists may have a strong incentive to redistribute resources (such as capital, pollution permits etc...) within the industry as a means of coordinating their output decision....

This paper analyzes the problem of altering the cost structure within an oligopoly, in the presence of costs of manipulation. Oligopolistic firms (which differ from each other in production costs) compete a la Cournot in the second stage, taking as given firm-specific taxees or input prices. In...

This paper analyzes features of perfect taxation also known as optimal taxation when one or more private markets is imperfectly competitive. Governments with perfect information and access to lump-sum taxes can provide corrective subsidies that render outcomes efficient in the presence of...

We analyse the incidence of ad valorem and unit excise taxes in an oligopolistic industry with diffentiated products and price-setting (Bertrand) firms.

This paper considers the relative efficiency of ad valorem and unit selective sales taxes in imperfectly competitive market. We provide a simple proof of the proposition that ad valorem taxes are welfare-superior to unit taxes in the short run whenproduction costs are identical across firms.
