We develop a structural gravity model that introduces scale effects in bilateral trade. Scale effects and incomplete passthrough give two channels through which exchange rates have real effects on trade patterns. Estimates from Canadian provincial trade data identify these effects through their...

I search for a %u201Cscale%u201D effect in countries. I use a panel data set that includes 200 countries over forty years and link the population of a country to a host of economic and social phenomena. Using both graphical and statistical techniques, I search for an impact of size on the level...

This paper extends the results of Rodrik (1998), Alesina and Wacziarg (1998), Ram (2009), Jetter and Parmeter (2015), Musau (2018) and other replication studies by providing dynamic panel estimates of the influence of country size and openness on government size. The estimates suggest that past...

The Panzar-Rosse model is a widely applied method to assess competitive conduct. In particular, it has been extensively used to analyze the competitive climate in the banking industry. To correct for differences in firm size, many empirical papers estimate a Panzar-Rosse revenue function with...

Do scale economies contribute to our understanding of international trade? Do international trade flows encode information about the extent of scale economies? To answer these questions we examine the large class of general equilibrium theories that imply Helpman-Krugman variants of the Vanek...

I search for a "scale" effect in countries. I use a panel data set that includes 200 countries over forty years and link the population of a country to a host of economic and social phenomena. Using both graphical and statistical techniques, I search for an impact of size on the level of income,...
