This paper reviews a number of recent contributions that demonstrate that a blend of welfare economics and statistical analysis is useful in the evaluation of the citations received by scientific papers in the periodical literature. The paper begins by clarifying the role of citation analysis in...

The main aim of this paper is to demonstrate that a blend of welfare economics and statistical analysis is useful in the evaluation of the distribution of the citations received by scientific papers in the periodical literature. The paper begins by reviewing the connection between basic...

This paper develops a model of trade and CO2 emissions with heterogenous firms, where firms make abatement investments and thereby have an impact on their level of emissions. The model shows that investments in abatements are positively related to firm productivity and firm exports. Emission...

This paper sheds light on the role of the impact of taxes on energy production versus tariffs on imported goods for trade, energy demand, and welfare. For this, we develop a structural Eaton-Kortum type general equilibrium model of international trade which includes an energy sector. We estimate...

We draw attention to the role of economic geography in explaining important cross-sectional facts which are difficult to account for in existing models of industrialization. By construction, closed-economy models that stress the role of local demand in generating sufficient expenditure on...

This paper presents a new model of the domino effect which is used to generate an empirical index of how "contagious" FTAs are with respect to third nations due to the trade diversion. We test our contagion hypothesis together with alternative specifications of interdependence and other...

The use of different currencies in the invoicing of international trade transactions plays a major role in the international transmission of economic fluctuations. Existing studies argue that an exporter’s invoicing choice reflects structural aspects of her industry, such as market share and...

We provide a novel set of stylized facts on firms engaging in international trade in services, using unique data on firm-level exports and imports from the world's second largest services exporter, the United Kingdom (UK). We show that only a fraction of UK firms engage in international trade in...

Existing estimates of power laws in firm size typically ignore the impact of international trade. Using a simple theoretical framework, we show that international trade systematically affects the distribution of firm size: the power law exponent among exporting firms should be strictly lower in...

A number of stylized facts have been documented about the extensive margin of trade - which firms export, and how many products they send to how many destinations. We argue that the sparse nature of trade data is crucial to understanding these stylized facts. Typically the number of observations...
