Competition for Firms in an Oligopolistic Industry: Do Firms or Countries Have to Pay?

We set up a model of generalised oligopoly where two countries of different size compete for an exogenous, but variable, number of identical firms. The model combines a desire by national governments to attract internationally mobile firms with the existence of location rents that arise even in a symmetric equilibrium where firms are dispersed. As economic integration proceeds, equilibrium taxes decline, switching from positive to negative levels, and then rise as trade costs fall even further. A range of trade costs is identified where economic integration raises the welfare of the small country, but lowers welfare in the large country

Skills, labour costs and vertically differentiated industries: A general equilibrium analysis

The effect of labour costs on industry profits, employment and labour income is at the heart of the current European debate on industry competitiveness. High wages paid in European countries such as Germany are generally considered harmful for industry profitability. Though, high wages appear also to be associated with high labour skills and then with superior product quality. Similarly, a reduction in labour taxes is often invoked as a tool to improve industry profitability, but this argument hardly takes into account the demand effects of such a tax reform. In this paper we analyse the trade-off between labour costs and industry profits by means of a simple general equilibrium model where one industry is oligopolistic and vertically differentiated. The manufacturing of products of a higher quality requires the employment of a larger amount of skilled labour. Given an underlying skills distribution, the model determines profits, wages and aggregate income and welfare. Results show that high net wages due to a low skills endowment in the economy are typically associated with low profits. Labour taxation unambiguously raises gross wages, but has little effect on net wages. Depending on how the tax revenue is redistributed, higher taxation may either depress or boost industry profits. --Vertical intra-industry trade,Quality differentiation,skills,productivity,labour cost

The Distribution of Tax Burdens: An Introduction

This paper summarizes important developments in tax incidence analysis over the past forty years. We mark the date of the beginning of modern tax incidence analysis with the publication of Harberger (1962) and discuss the relation of subsequent work to this seminal paper.

Indirect Taxation in Vertical Oligopoly

This paper analyzes the effects of specific and ad valorem taxation in an industry with downstream and upstream oligopoly. We find that in the short run, i.e. when the number of firms in both markets is exogenous, the results concerning tax incidence tend to be qualitatively similar to models where the upstream market is perfectly competitive. However, both over- and undershifting are more pronounced, potentially to a very large extent. Instead, in the long run under endogenous entry and exit overshifting of both taxes is more likely to occur and is more pronounced under upstream oligopoly. As a result of this, a tax increase is more likely to be welfare reducing. We also demonstrate that downstream and upstream taxation are equivalent in the short run while this is not true for the ad valorem tax in the long run. We show that it is normally more efficient to tax downstream

Industry Trade-Balance and Domestic Merger Policy: Some Empirical Evidence from the U.S.

The literature on antitrust in an open-economy setting is inconclusive with respect to the role played by trade-balance on the tenor of domestic merger policy. Using a panel data set composed of US merger reviews by industrial sector over the 1997-2001 period, I empirically test the impact of sectoral trade balance on the level of antitrust scrutiny. The results suggest that larger trade balances lead to more vigorous antitrust scrutiny; thus, ‘strategic’ merger policy does not appear evident, and consumer-surplus appears to guide US merger policy even under the lure of international competitive gains. ZUSAMMENFASSUNG - (Empirische Evidenz über den Zusammenhang von Leistungsbilanz und Fusionspolitik in den U.S.A.) Die "anti-trust"-Literatur bezogen auf eine offene Volkswirtschaft sagt wenig dazu aus, welche Rolle die Leistungsbilanz für die Fusionspolitik eines Landes spielt. In diesem Papier wird anhand von Paneldaten, in denen die Berichte der Fusionskontrolle in unterschiedlichen Industrien der U.S.A. über einen Zeitraum von 1997-2001 zusammengestellt sind, empirisch getestet, welchen Effekt die Leistungsbilanzen - nach Industriezweigen unterteilt - auf das Niveau der "antitrust"- Kontrolle haben. Die Ergebnisse der Tests deuten an, dass mit größerem Leistungsbilanzgewicht auch eine strengere "anti-trust"-Kontrolle einhergeht. Folglich ist eine "strategische" Fusionspolitik der U.S.A. nicht zu erkennen. Stattdessen scheint die US-amerikanische Fusionspolitik stark vom Verbrauchernutzen geleitet zu sein, trotz der Verheißung internationaler Wettbewerbsvorteile.Merger Policy, International Effects, Open Economy

An Alternate Approach to Theory of Taxation and Sources of Public Finance in an Interest Free Economy

This unique study discusses the theory of taxation in Islam and the role of Zakat in an Islamic economy. Zakat is a compulsory payment i.e. a tax in this sense paid to the government on one’s income and wealth. The Zakat rates are studied for their viability and effectiveness to fulfill fiscal needs of the government. Based on the evidence from many countries, it is argued that Zakat rates are substantial enough to generate the needed public finance given the large tax base and free the government from using seignorage and deficit financing. Its compulsory nature both as per law of the land and as per religion would ensure minimum tax evasion and its progressive and direct nature would effectively redistribute income. The effect of Zakat on the overall macroeconomy, the financial system, monetary system, property market, stock market, inflation, foreign debt, balance of payments, FDI and the on the development oriented variables like inequality and poverty are also discussed to give a holistic view of the effects of the proposed system.Interest free economy, Public finance, Taxation, Inequality, Income redistribution, Islamic Economic System, fiscal policy, deficit financing.

Tax Analysis in an Oligopoly Model

In this paper we analyze taxation using the conjectural variations model of oligopoly. We demonstrate the way in which the incidence of a tax depends upon the pattern of firm interaction. The results obtained have important implications for the controversy surrounding the question of whether a tax oncorporate income can be over-shifted. We also study normative aspects of taxation. The focus here is on the errors that can arise in excess burden calculations when incorrect assumptions on market structure are made.
