This paper analyzes secessions through the lens of representative democratic institutions and considers the incentives of partisan political parties to support independence movements.  It points out that, if anything, separatists should expect to receive support from exactly the "unlike-minded"...

Little is known about the extent and forces of urban path dependence in developing countries.  Railroad construction in colonial Kenya provides a natural experiment to study the emergence and persistence of this spatial equilibrium.  Using new data at a fine spatial level over one century...

This paper shows that Zipf's Law for cities can emerge as a property of a clustering process.  If initially uniformly distributed people chose their location based on a specific gravity equation as found in trade studies, they will form cities that follow Zipf's Law in expected value.  This...

We develop a new methodology for quantifying the tasks undertaken within occupations using 3,000 verbs from around 12,000 occupational descriptions in the Dictionary of Occupational Titles (DOTs).  Using micro-data from the United States from 1880-2000, we find an increase in the employment...

This paper examines how economic activity and market participation are distributed across space. Applying a non-parametric von Thünen model to Nepalese data, we uncover a strong spatial division of labor. Non-farm employment is heavily concentrated in and around cities while agricultural wage...

When European powers partitioned Africa, individuals of otherwise homogeneous communities were divided and found themselves randomly assigned to one coloniser. This provides for a natural experiment: applying a border discontinuity analysis to Ghana and Togo, we test what impact...

This paper studies the recent trends in the spatial distribution of economic activity in the United States. Using county-level employment data for 13 sectors - which cover the entire economy - we apply semi-parametric techniques to estimate how agglomeration and congestion effects have changed...

Urbanization has been extensively used as a proxy for economic activity.  The urban status of settlements is usually determined by an ad hoc population size household.  This paper proposes a new threshold, taking into account the effect of local agricultural endowments.  The new population...

This paper examines the spatial distribution of jobs across US counties and investigates whether sectoral employment is becoming more or less concentrated. The existing literature has found deconcentration (convergence) of employment across urban areas. Cities only cover a small part of the US,...
