The active spread of COVID-19 and the resulting containment measures have made it clear that both supply demand global production networks are facing unprecedented shocks disruptions. Accordingly, this has resulted in an urgent need to investigate countries’ competitive situation (and its changes) during a prolonged period uncertainty. This study aims assess impact pandemic on revealed comparat...

We study the evolution of comparative advantage in a model with two countries and`≥ 2 goods. We show that the stochastically stable set consists of the pattern of production that follows the chain of comparative advantage in a sufficiently large world economy. Also, the chain of comparative advantage has an elegant structure that allows for step-by-step evolution. So convergence towards the equ...

We propose a model of social interactions based on comparative advantage. When comparative advantage is the guiding principle of social interactions, the effect of moving a student into an environment with higher-achieving peers depends on where in the ability distribution she falls and the shadow prices that clear the social market. We show that the model’s key prediction–an individual’s ordin...

This paper constructs and structurally estimates a dynamic occupational choice model that has two distinct features. First, an occupation is vertically and horizontally differentiated by a multidimensional task complexity measure. This allows a simultaneous analysis of career progression and comparative advantage. Second, the model includes hundreds of occupations by characterizing all jobs by ...

We analyze the dynamics of Chinese comparative advantage as measured by export shares and the Balassa index using 3-digit and 4-digit sectors for the period 1970 – 1997. We use novel tools to identify periods of rapid structural change and the persistence of comparative advantage, such as Galtonian regressions, probability-probability (p-p) plots, and the Harmonic Mass index, to supplement the ...
