The objective of this paper is to provide indicators of trade restrictiveness that include both measures of tariff and nontariff barriers for 91 developing and industrial countries. For each country, the authors estimate three trade restrictiveness indices. The first one summarizes the degree of...

To study the effects of tariffs on gross domestic product (GDP), one needs import demand elasticities at the tariff line level that are consistent with GDP maximization. These do not exist. The authors modify Kohli's (1991) GDP function approach to estimate demand elasticities for 4,625 imported...

This paper assesses the foreign lobbying forces behind the tariff preferences that the United States grants to Latin American and Caribbean countries. The basic framework is the one developed that is extended to explain the relationship between foreign lobbying and tariff preferences. Results...

Bilateral trade relationships between countries vary across products. Such heterogeneity poses challenges when assessing the economic impacts of trade agreements. This paper estimates bilateral trade elasticities at the product level and explores these impacts using a hypothetical no-deal Brexit...

To understand the role of trade policies in the crisis of 2008, this paper constructs the overall trade restrictiveness indices for a wide range of countries using their tariff schedules in 2008 and 2009. The index summarizes the trade policy stance of a country, taking into account the share of...

Under the Kyoto Protocol, industrialized countries (called Annex I countries) have to reduce their combined emissions to 5 percent below 1990 levels in the first commitment period of 2008-12. Efforts to reduce emissions to meet Kyoto targets and beyond have raised issues of competitiveness in...

The results of this paper challenge the conventional wisdom in the literature that productivity plays no role in the economic development of Singapore. Properly accounting for market power and returns to scale technology, the estimated average productivity growth is twice as large as the...

Product variety plays an important role in the theoretical work on monopolistic competition and trade, and recent empirical work has begun to quantify this for aggregate and disaggregate import demands. The authors discuss the measurement of product variety in trade, using a broad cross-section...

What major insights have emerged from development economics in the past decade, and how do they matter for the World Bank? This challenging question was recently posed by World Bank Group President David Malpass to the staff of the Development Research Group. This paper assembles a set of 13...

The authors present a model of endogenous growth in which the main engine of economic development is knowledge. Using a two-sector closed economy model that comprises of a conventional goods-producing sector and a research and development sector, their model incorporates two key aspects of...
