We use a version of the Meade model to consider the effects of interdependent import tariffs in the presence illegal immigration. First, we consider the small union case and derive the Nash tariff equilibrium for two potential members of a Preferential Trade Agreement (PTA). We analyze...

Advertisements provide consumers with knowledge about private products, whereas political information is required to provide voters with knowledge of public issues. Modern information technologies and globalization are increasing the exposure of individuals to information. Goods advertising is...

We propose a novel structural method to empirically identify economies of scale in household consumption. We assume collective households with consumption technologies that define the public and private nature of expenditures through Barten scales. Our method recovers the technology by solely...

The division of labor between and within countries is driven by two fundamental forces, comparative advantage and increasing returns. We set up a simple Ricardian model with a Marshallian input sharing mechanism to study their interplay. The key insight that emerges is that the interaction...

This paper evaluates the effectiveness of a widely used sanitation intervention, Community-Led Total Sanitation (CLTS), using a randomized controlled trial. The intervention was implemented at scale across rural East Java in Indonesia. CLTS increases toilet construction, reduces roundworm...

We analyse the implications of unions (efficient bargaining) for multiplicity of stationary states and welfare, local indeterminacy, bifurcations and endogenous fluctuations (deterministic and stochastic). We use an overlapping generations model with external increasing returns to scale, where...

When comparing economic well-being using income or expenditures, an equivalence scale is often used to adjust for differences in characteristics that affect needs. For example, a family of two is assumed to need more income than a single person, but not twice as much due to the economies of...
