This paper exploits exogenous features of the 1960s/70s container revolution to estimate the impact of the introduction of refrigerated containers (or reefers) on new trade of temperature sensitive products. Our identification strategy is justified by a historical narrative which suggests that...

Since the 1970s, exports and imports of manufactured goods have been the engine of international trade and much of that trade relies on container shipping. This paper introduces a new monthly index of the volume of container trade to and from North America. Incorporating this index into a...

We quantify the effect of container technology on transport costs and trade by estimating the modal choice between containerization and breakbulk shipping using micro-level trade data. The model is motivated by novel facts that relate container usage to shipment, destination and firm...

This paper examines the effects of port development on the economy. By using scarce local land intensively, ports put pressure on local land prices and crowd out other forms of economic activity. We use the introduction of containerized shipping – a technology that substantially increased land...

One of the core indicators in the field of scientometrics is the number of papers published by a unit within a given period. However, such indicators can only be assessed properly by considering the unit’s available resources. When evaluating the efficiency of institutions worldwide, the...

We compute confidence intervals for recursive impact factors, that take into account that some citations are more prestigious than others, as well as for the associated ranks of journals, applying the methods to the population of economics journals. The Quarterly Journal of Economics is clearly...

Differences in annual publication counts may reflect the dynamic of scientific progress. Declining annual numbers of publications may be interpreted as missing progress in field-specific knowledge. In this paper, we present empirical results on dynamics of progress in economic fields (defined by...

We analyze whether the social media popularity of Twitter star scientists, who were identified by Science in a 2014 report, pays off in terms of an increased number of citations. To establish a causal relationship, we use the COVID-19 global pandemic as a quasi-natural experiment exogenously...
