Since firm heterogeneity has been introduced into international trade models, the importance of firm entry and exit (the extensive margin) has been highlighted. Thomas Chaney (2008) illustrates how accounting for heterogenous firms (and this extensive margin) alters the standard gravity...

We present a gravity model that accounts for multilateral resistance, firm heterogeneity and country-selection into trade, while accommodating asymmetries in trade flows. A new equation for the proportion of exporting firms takes a gravity form, such that the extensive margin is also affected by...

We propose a quantity-based 'dual' version of the gravity equation that yields an estimating equation with both cross-sectional interdependence and spatially lagged error terms. Such an equation can be concisely estimated using spatial econometric techniques. We illustrate this methodology by...

Mainstream economic wisdom favoring cooperative free trade is challenged by a wave of disruptive trade policies. In this paper, we provide quantitative evidence concerning the economic impacts of tariffs implemented by the United States in 2018 and the subsequent retaliations by partner...

This dissertation was prepared by Alexander-Nikolai Sandkamp, completed in September 2018 and first published online by LMU Munich in February 2019. It consists of four selfcontained chapters that empirically investigate different trade dampening phenomena using gravity analysis. The first two...

This paper investigates the sources and size of trade barriers at the industry level. We derive a micro-founded measure of industry-specific bilateral trade integration that has an in-built control for time-varying multilateral resistance. This trade integration measure is consistent with a...

Estimates for ad valorem tariff equivalents of services trade restrictions for cross-border trade in six services sectors are presented in this paper. These equivalents are found to be very big in several service sectors with estimates ranging as high as 2000% when trade flows are relatively...

Over the past two decades, governments worldwide have continued to liberalise restrictions on international investment with only occasional relapses. Yet, FDI liberalisation remains an unfinished agenda in various parts of the world and across sectors. This paper sheds light on their potential...
