When allocating a resource, geographical and infrastructural constraints have to be taken into account. We study the problem of distributing a resource through a network from sources endowed with the resource to citizens with claims. A link between a source and an agent depicts the possibility...

In a moneyless market, a non storable, non transferable homogeneous commodity is reallocated between agents with single-peaked preferences. Agents are either suppliers or demanders. Transfers between a supplier and a demander are feasible only if they are linked, and the links form an arbitrary...

Suppose that individual payoffs depend on the network connecting them. Consider the following simultaneous move game of network formation: players announce independently the links they wish to form, and links are formed only under mutual consent. We provide necessary and sufficient conditions on...

Measuring labor's share of an economy's aggregate income seems straightforward,at least in principle. Count up wage and salary income, along with the value of benefitsprovided to employees, and divide it by total income. However, one fundamentalconcept of labor's share in macroeconomic theory is...

We test the existence of changes in the relationship between fertility and schoolingin Colombia for women from 30 to 40 years old between 1995 and 2005. For ourpurpose, we use Poisson Regression Models. Our database is the Demographic andHealth Survey from 1995 and 2005. We found a reduction in...

This study examines the determinants of information and communications technology(ICT) use and access of low-income people in three developing countries: Colombia,Mexico and Peru. We focus on cross-country differences and similarities in ICTs use acrossgender, age, education and income, using...

We formulate and solve a model of factor saving technological improvement considering three factors of production: labor, capital and energy. The productive activities have three main characteristics: …first, in order to use capital goods fi…rms need energy; second, there are two sources of...

This paper proposes a simple Ordered Probit model to analyse the monetary policy reactionfunction of the Colombian Central Bank. There is evidence that the reaction function isasymmetric, in the sense that the Bank increases the Bank rate when the gap between observedinflation and the inflation...
