A UNIFIED PRESENTATION OF COMPETITION ANALYSIS IN TWO-SIDED MARKETS

The goal of this paper is to present quantitative tools to manage competition policy analysis in two-sided platforms, based on a common framework for transaction and non-transaction platforms. We explore tools for relevant market definition [Critical Loss Analysis and a small but significant non-transitory increase in price (SSNIP) test], unilateral effects indicators [Upward Pricing Pressure (UPP) and Gross Upward Pricing Pressure Index (GUPPI)] and tests for exclusionary practices. We review dispersed results in the literature and fill the gaps where appropriate. We highlight the required changes from the usual one-sided market framework and tools. While discussions of antitrust tools can be found in specialized forums devoted to advances in competition policy analysis, we organize the material in an integrated framework.     

Divergence in Reservation Prices and Its Impact on Housing Market Liquidity: A Theoretical Analysis

In this paper, we build a two-period English auction model to study the relative movements between buyers’ and sellers’ reservation prices in the housing market. We show that changes in sellers’ reservation prices are jointly determined by changes in buyers’ reservation prices, probability of buyers offering a high or low price, and the arrival rate of buyers. When the divergence between the buyers’ and sellers’ reservation prices widens, the probability of sale increases in the upward market and decreases in the downward market, contributing to the increases or decreases in market liquidity.     

THE EFFECTS OF PENSION FUNDS ON MARKETS PERFORMANCE: A REVIEW

The worldwide reforming process of pension systems triggered by the demographic transition and globalization has led several countries to implement multi‐pillar pension systems and enhance pension funds. For this reason the studies on the effects that pension funds exert on markets performance have been flourishing in the last decades. In this paper, we provide an updated review of the empirical advances in this field of study, with particular focus on the effects that pension funds produce on labour markets, financial markets and economic growth.     

RADICALISM VERSUS GRADUALISM: AN ANALYTICAL SURVEY OF THE TRANSITION STRATEGY DEBATE

Academic debate on a transition strategy for former socialist economies continues even a quarter century after the collapse of the communism in Central and Eastern Europe and the former Soviet Union. In this paper, through an analytical survey of 137 preceding studies, we present an overall picture of the debate and examine the relationship between the debate attitudes and the literature attributes in related studies. We found that the radicalists maintain a consistent debate attitude from the viewpoints of time speed and policy sequence of economic transition, while the debate attitude of the gradualists is more diversified. We also found that there is another group of researchers that stays within the framework of the radicalism‐versus‐gradualism debate while at the same time keeping at arm's length from both the radicalists and the gradualists. In addition, our regression estimation of qualitative selection models provides interesting findings on the relationship between the debate attitudes and the literature attributes.     

THE DEBATE ABOUT THE REVIVED BRETTON‐WOODS REGIME: A SURVEY AND EXTENSION OF THE LITERATURE

This paper surveys the literature dealing with the thesis put forward by Dooley, Folkerts‐Landau and Garber (DFG) that the present constellation of global exchange‐rate arrangements constitutes a revived Bretton‐Woods regime. DFG also argue that the revived regime will be sustainable, despite its large global imbalances. While much of the literature generated by DFG's thesis points to specific differences between the earlier regime and revived regime that render the latter unstable, we argue that an underlying similarity between the two regimes renders the revived regime unstable. Specifically, to the extent that the present system constitutes a revived Bretton‐Woods system, it is vulnerable to the same set of destabilizing forces – including asset‐price bubbles and global financial crises – that marked the latter years of the earlier regime, leading to its breakdown. We extend the Markov switching model to examine the relation between global liquidity and commodity prices. We find an evidence of commodity‐price bubbles in both the latter stages of the earlier Bretton‐Woods regime and the revived regime.     

INNOVATION,COMPETITION AND ANTITRUST: AN EXAMINATION OF THE INTEL CASE

Microprocessor‐maker Intel has been subjected to the highest fine in the history of EU competition policy. Intel operates in a market with one other main supplier, a fact that seemed to provide grounds to those accusing it of abusing a dominant position. The authors argue that, in spite of the limited number of players, the microprocessor market showed the distinctive marks of dynamic competition: ever‐lower prices and ever‐growing innovation. Political considerations more than sound economic reasoning seem to be behind the EU antitrust decision.     

AGAINST LEVIATHAN: A REVIEW OF CLASSICAL LIBERALISM IN THE 21ST CENTURY: ESSAYS IN HONOUR OF NORMAN P. BARRY1

Classical Liberalism in the 21st Century is a collection of essays from colleagues and friends of the late Norman Barry, Professor of Social and Political Theory at the University of Buckingham. Most share Barry's Hayekian perspective. The essays cover themes such as: international competition in trade and between jurisdictions; the corporate social responsibility fad; secular economic errors; policies relating to alleged global warming; the state's impotence at removing externalities; the moral functions of competition; and, above all, Barry's rigour and eloquence in the economic and political case for freedom.     

RISK‐COPING,LAND TENURE AND LAND MARKETS: AN OVERVIEW OF THE LITERATURE

Over the last decades, a significant amount of literature has been published on informal risk‐coping in developing countries. In this paper, we review how informal risk‐coping has been addressed in the land tenure literature from two main perspectives: a first stream of research looks at how customary tenure and communal property perform key informal risk‐coping functions. A second subset of this literature analyses how informal risk‐coping creates land market imperfections through sharecropping or distress sales. The segmentation of the literature results from the Demsetzian property rights framework. Further research on risk‐coping and land tenure would benefit from examining recent work on property regimes.     

CHALLENGING THE CHALLENGERS: A REVIEW OF SERENA OLSARETTI'S LIBERTY, DESERT AND THE MARKET AND DANIEL ATTAS'S LIBERTY, PROPERTY AND MARKETS

These books attack free markets and libertarianism, alleging that their fundamental assumptions are philosophically indefensible. Olsaretti challenges the thesis that free markets produce distributively just outcomes. At most, however, she shows that limited, desert-based justifications of free-market outcomes fail to satisfy her questionable desiderata, and that particular entitlement-based justifications are inadequately supported when they confound voluntariness and freedom. Attas challenges libertarianism itself, claiming that it is fundamentally wrong, and that libertarian notions of property rights are unsustainable. But he considers only arguments based on defective notions of self-ownership and confused notions of freedom; other, more robust justifications of liberty and property are ignored. Though both of these books fail to demonstrate the strong conclusions they assert, they highlight the dangers of substituting polemic for philosophy. Free markets, property and liberty need, and deserve, rigorous philosophical defences.     

CHINESE EXPERIENCE IN THE INTRODUCTION OF A MARKET MECHANISM INTO A PLANNED ECONOMY: THE ROLE OF PRICING

Abstract. A brief review is first presented of the changes in pricing institutions in China since 1949, with particular emphasis on the shift from an equilibrium price system to a distorted price system. The authors argue that distorted prices are harmful to economic growth even in a planned economy, since even an experienced economic planner can never escape from the full implications of a distorted price system. Examples are given showing the detrimental results of such a system. The central point of China's economic reform is the extension of decision-making power to enterprises and the introduction of a market mechanism so as to improve microeconomic efficiency. But such a goal cannot easily be achieved due to the false information provided by the distorted price system. So price adjustment becomes an issue of primary importance, and the authors discuss the difficulties for price adjustment posed by various interest groups.     

WHAT DETERMINES THE ELASTICITY OF SUBSTITUTION BETWEEN CAPITAL AND LABOR? A LITERATURE REVIEW

This paper provides the first comprehensive review of the empirical and theoretical literature on the determinants of the elasticity of substitution between capital and labor. Our focus is on the two-input constant elasticity of substitution (CES) production function. We start by presenting four concise observations that summarize the empirical literature on the estimation of . Motivated by these observations, the main part of this survey then focuses on potential determinants of capital–labor substitution. We first review several approaches to the microfoundation of production functions where the elasticity of substitution (EOS) is treated as a purely technological parameter. Second, we outline the construction of an aggregate elasticity of substitution (AES) in a multi-sectoral framework and investigate its dependence on underlying intra- and inter-sectoral substitution. Third, we discuss the influence of the institutional framework on the extent of factor substitution. Overall, this survey highlights that the effective elasticity of substitution (EES), which is typically estimated in empirical studies, is generally not an immutable deep parameter but depends on a multitude of technological, non-technological, and institutional determinants. Based on these insights, the final section identifies a number of potential empirical and theoretical avenues for future research.     

PATENT ENFORCEMENT: A REVIEW OF THE LITERATURE

Without the confidence that patent rights can be enforced quickly and efficiently, when needed, the patent system will not stimulate innovation. For this reason, governments, academics, international institutions and the private sector have poured significant resources into gathering and analysing statistics on patent enforcement over the last two decades. This paper reviews these studies and finds that while infringement is relatively common, much enforcement occurs informally and less than 1–2% of patents incur litigation. New strategic uses of the enforcement system, especially by nonpracticing entities, are the major emerging enforcement issue, especially in the United States. While the old problem of litigation costs attracts the lion's share of empirical attention, it has produced remarkably few solutions to date.     

CHILD LABOUR: A REVIEW OF RECENT THEORY AND EVIDENCE WITH POLICY IMPLICATIONS

In recent years, a growing number of authors have turned their attention to the question of why children work. The purpose of this paper is to review some of the more recent theoretical and empirical research into the topic of child labour, and to illustrate the fact that no one factor on its own can account for the phenomenon of child labour. Therefore, policies aimed at eradicating child labour will need to address the broad range of underlying factors that contribute to the incidence of child labour, such as poverty, market imperfections and access to education.     

LOCAL LABOR MARKETS AND NATURAL RESOURCES: A SYNTHESIS OF THE LITERATURE

A primary way that natural resources affect a locality is through the demand for labor, with greater extraction requiring more workers. Shifts in labor demand can be measured through changes in employment and earnings, the main labor market outcomes, or through changes in the population and income, more generally. These changes may spillover into the nonresource economy, leading to greater overall effects or possibly crowd out; be spread unequally across the population, thereby altering the distribution of income and the poverty rate; or influence educational attainment, as people choose between additional schooling and work. In this review, the literature linking natural resources to local labor markets is synthesized by organizing existing studies according to their resource measurement and the outcomes that they consider. This synthesis provides an accessible guide to a literature that has boomed in recent years. It also identifies promising avenues for future research and lays a foundation to further generalize the evidence through an eventual meta‐analysis.     

PRECAUTIONARY SAVING: A REVIEW OF THE EMPIRICAL LITERATURE

Standard macroeconomic models show that uncertainty plays a significant role in consumption and saving decisions under rather mild conditions, namely the convexity of the marginal utility of consumption. Increased uncertainty generates a positive extra saving, the so‐called ‘precautionary saving’. Although this hypothesis has been tested by a large number of authors, both at macro and micro level, the empirical results are not conclusive, and the main conclusion than can be drawn is that there is neither consensus on the intensity of that motive for saving, nor on the most appropriate measure of uncertainty. This paper provides a comprehensive review of the empirical literature discussing the main controversial issues and the different approaches followed by the studies addressing empirically the test of precautionary saving.     

THE POLITICAL ECONOMY OF ENVIRONMENTAL CONSEQUENCES: A REVIEW OF THE EMPIRICAL LITERATURE

As a key concern for human survival and development, environmental issues have been widely perceived to be impacted by various political institutional factors. A considerable body of literature has attempted to investigate how different political factors affect environmental policymaking and outcomes. In this paper, we critically review related scholarly works published in peer‐reviewed economic journals in the past 30 years, with an emphasis on the empirical literature. Political institutional factors considered in this survey include corruption, the general concept and specific elements of democracy, and the vertical structure of environmental regulation authority within different levels of governments (i.e. environmental federalism). Studies focusing on the interplay of these factors are also highlighted. Based on a critical review, we provide a guide to the datasets, methodologies, and main findings of the literature. We also point out the existing gaps, and put forward suggestions for future research directions.     

PRICE DISCRIMINATION: A SURVEY OF THE THEORY

Abstract. The purpose of this survey is twofold. First, it introduces the reader to recent developments in the theory of price discrimination. Simultaneously, the exposition aims at being self-contained and accessible to the non-specialist reader. The paper is structured around Pigou's distinction between perfect, second-degree and third-degree price discrimination.     

THE GINI CONCENTRATION INDEX: A REVIEW OF THE INFERENCE LITERATURE

More than a century ago, Corrado Gini proposed his well-known concentration index for measuring the degree of inequality in the distribution of income and wealth. His index is still extremely relevant and widely used in several fields of research and application. In this paper, we focus on the inferential properties of the Gini index, and discuss the main directions of analysis proposed in the literature. The aim of the paper is to provide a comprehensive review of the main developments on the inferential aspects of the Gini concentration ratio. We feel that this work can provide a valuable contribution to those scholars who are approaching the large amount of literature on the inferential properties of the Gini index.     

MODELS OF BANKING INSTABILITY: A PARTIAL REVIEW OF THE LITERATURE

Abstract. This paper critically examines the theoretical literature on banking instability that has followed Diamond and Dybvig (1983). It explores the extent to which it (a) explains banking instability within a theoretical context in which financial intermediaries improve on unintermediated markets, and (b) justifies government involvement in the financial intermediation industry. It suggests that the literature has yet to provide a satisfactory theoretical basis for banking instability as such since the intermediaries which arise from it are peculiar mutual funds that bear little resemblance to real-world banks. In addition, the paper challenges the widespread belief that this literature provides a sound foundation for government involvement in the industry. It suggests that arguments for government intervention are open to objection on various grounds, the most important one being that they are inconsistent with the existence of properly motivated financial intermediation in these models.     

FROM THE LAB TO THE FIELD: A REVIEW OF TAX EXPERIMENTS

Tax experiments have been gaining momentum in recent years, although this literature dates back several decades. With new developments in methods and data availability, tax experiments have gradually moved away from lab settings and towards the field. This movement from the lab to the field has happened against the background of the ‘credibility revolution’ in applied economics, which has seen more rigorous methods applied to policy relevant questions, and of the availability to researchers of administrative data from tax returns. These developments have allowed significant advances in the experimental literature on tax compliance. This paper reviews this literature, giving particular attention to field experiments using administrative data, but putting them in the broader context of the compliance literature. A particular effort is made to take a global perspective, in a literature that is only recently seeing the emergence of evidence from Africa, Latin America and Asia.
