El artículo explora el efecto del consumo de tecnologías sanitarias sobre la probabilidad de morir, a diferentes niveles de deterioro del estado de salud de los individuos. Se emplearon registros de la base de datos de suficiencia, de la Unidad de Pago por Capitación, que cuenta con información de atenciones de aproximadamente 28 millones de colombianos, entre los años 2013 y 2019.

How do political parties decide how to allocate campaign resources between vote-buying and traditional campaigning? This decision ultimately determines the presence and extent of vote-buying. Nevertheless, we lack a proper understanding of how this decision is made. This paper aims to fill this gap by building a political competition model with two political parties, brokers, and expressive and non-expressive citizens who value political ideology and public goods.

A key topic in social science is explaining why states are organized in very different ways with important consequences for economic prosperity. In this research we use the history of Colombian paramilitarism to advance a new hypothesis about it: the organization of the state fundamentally reflects the kinship structure of society. We lay out a model in which more central commanders within the networks of paramilitary groups elicit greater effort from their combatants, an effect that is complementary to recruiting more kin members (i.e., family) .

This paper studies how dealers provide liquidity in over-the-counter (OTC) markets during an acute crisis when they can choose their capacity: how fast they can execute orders and their inventories. I develop a search model of an OTC market in which trade between homogeneous dealers is centralized, but trade with investors is subject to search frictions proportional to dealer order execution rates.

Do the macroeconomic effect of a carbon tax differ between countries, according to the primary energy source? I answer this question with a theoretical model of directed technical change and test empirically the main results.

We explore the phenomenon of "jobless industrialization" in late-industrializing countries.

Can radio campaigns affect fertility? This paper examines the impact of a national radio campaign promoting family planning clinics in late 1960s Colombia on the country's rapid fertility decline. The campaign, initiated by Profamilia in 1969, provided information about the location of clinics without providing detailed contraceptive information. Using data from the full count 1973 census and information on clinic locations and radio programs, the study leverages exogenous variation in radio signal strength to estimate the campaign's effect on fertility.

This paper examines the link between industrial production and the sentiment expressed in natural language survey responses from U.S. manufacturing firms. We compare several natural language processing (NLP) techniques for classifying sentiment, ranging from dictionary-based methods to modern deep learning methods. Using a manually labeled sample as ground truth, we find that deep learning models--partially trained on a human-labeled sample of our data--outperform other methods for classifying the sentiment of survey responses.
