The increasing literature on the interactions between liberalization-integration of product markets and labour market reforms is often highly speculative and draws on a rather weak empirical basis. Cross-country indicators of regulatory frameworks are often lacking, making it difficult to...

Simplifying entry regulation has been a popular reform since the publication of Djankov et al (2002). The inclusion of business entry indicators in the World Bank’s Doing Business project has led to an acceleration in reform: in 2003-2008, 193 reforms took place in 116 countries. A large...

Motivated by the regulatory debate in electricity markets, we seek to understand how market design affects market performance through its impact on investment incentives. For this purpose, we study a two-stage game in which firms choose their capacities under demand uncertainty prior to bidding...

We investigate the relationship between financial integration and output volatility at micro and macro levels. Using a very large firm-level dataset (AMADEUS) from 16 European countries, we construct a measure of ``deep'' financial integration at the regional level based on observations of...

This paper surveys the recent literature on Arab economic integration, discusses the goals and progress that has been made to date and some of the key policy, regulatory and political factors that underpin the segmentation of Arab markets. It argues that there has been an excessive focus by both...

We construct a three-country, two-bloc, multi-product trade model in which tariff agreements between customs union members are binding whereas inter-bloc tariff agreements are self-enforcing. Our main objective is to explore how the liberalization of trade between customs union members (i.e. the...

The paper analyses the debate on the relationship between trade liberalization and the harmonization of social policies in the context of European integration. It is divided into two parts. The first shows that harmonization of social policies was not imposed in the 1960s and 1970s as a...

Many commentators purport to use the Kemp-Wan Theorem to discuss the effects of regional integration schemes on non-member countries, and to operationalize the theorem in terms of the share of member countries' imports from non-members. This paper shows that Kemp and Wan (1976) say nothing about...

We consider a simple three-country, multi-commodity trade model in which two custom union members that have successfully coordinated their external tariff policies are in the process of deepening the integration of their internal markets through the removal of tariffs on intra-union trade. Union...

This paper examines the theoretical arguments and historical evidence about whether regionalism undermines the multilateral trading system. It first considers how to define multilateralism and then surveys over 60 recent contributions to the literature. It classifies theoretical models by four...
