Anti-drug policies in Colombia : successes, failures, and wrong turns by Alejandro Gaviria( )

7 editions published between 2015 and 2016 in English and held by 604 WorldCat member libraries worldwide

"This book compiles the most up-to-date research and evidence on the different dimensions of drugs and drugs policy in Colombia, a country that has done everything possible to fight illicit drug production and trafficking"--
The war against drug producers by Herschel I Grossman( )

9 editions published in 2005 in English and held by 94 WorldCat member libraries worldwide

"This paper develops a model of a war against the producers of illegal hard drugs. This war occurs on two fronts. First, to prevent the cultivation of crops that are the raw material for producing drugs the state engages the drug producers in conflict over the control of arable land. Second, to impede further the production and exportation of drugs the state attempts to eradicate crops and to interdict drug shipments. The model also includes an interested outsider who uses both a stick and a carrot to strengthen the resolve of the state in its war against drug producers. The results of the calibration of the model yield an estimate that from 2001 through 2003 subsidies from the United States to the Colombian armed forces under Plan Colombia caused a decrease in the exportation of drugs from Colombia to about 44 percent of what exportation was before Plan Colombia was implemented. The results of the calibration of the model also suggests that a more efficient allocation of the about $2 billion that the United States spent on Plan Colombia through 2003 would have involved larger subsidies to the conflict over control of arable land and smaller subsidies to eradication and interdiction efforts"--National Bureau of Economic Research web site
Cocaine production and trafficking : what do we know? by Daniel Mej??a( )

1 edition published in 2008 in English and held by 53 WorldCat member libraries worldwide

The main purpose of this paper is to summarize the information currently available on cocaine production and trafficking. The paper starts by describing the available data on cocaine production and trade, the collection methodologies (if available) used by different sources, the main biases in the data, and the accuracy of different data sources. Next, it states some of the key empirical questions and hypotheses regarding cocaine production and trade and takes a first look at how well the data match these hypotheses. The paper states some of the main puzzles in the cocaine market and studies some of the possible explanations. These puzzles and empirical questions should guide future research on the key determinants of illicit drug production and trafficking. Finally, the paper studies the different policies that producer countries have adopted to fight against cocaine production and the role consumer countries play in the implementation of anti-drug policies
Políticas antidroga en Colombia : éxitos, fracasos y extravíos by Alejandro Gaviria( Book )

7 editions published between 2011 and 2012 in Spanish and held by 53 WorldCat member libraries worldwide

Forty years after president Richard Nixon declared the "war against drugs", the debate about the efficiency and cost of the prohibition is still as vigorous as ever. The book, divided in 5 sections covers diverse topics related to the economics and social aspects of illegal drugs through a series of analytical texts and political recommendations on the formulation of more effective anti-drug general policies based in available evidence on what works, without paying attention to political statements and preconceived ideologies
Cocaine production and trafficking : what do we know? by Daniel Mejia( )

Abstract: The main purpose of this paper is to summarize the information currently available on cocaine production and trafficking.

Next, it states some of the key empirical questions and hypotheses regarding cocaine production and trade and takes a first look at how well the data match these hypotheses. The paper states some of the main puzzles in the cocaine market and studies some of the possible explanations. These puzzles and empirical questions should guide future research on the key determinants of illicit drug production and trafficking. Finally, the paper studies the different policies that producer countries have adopted to fight against cocaine production and the role consumer countries play in the implementation of anti-drug policies
On the effects of enforcement on illegal markets : evidence from a quasi-experiment in Colombia by Daniel Mejia( )

2 editions published in 2015 in English and held by 38 WorldCat member libraries worldwide

This paper studies the effects of enforcement on illegal behavior in the context of a large aerial spraying program designed to curb coca cultivation in Colombia. In 2006, the Colombian government pledged not to spray a 10 km band around the frontier with Ecuador due to diplomatic frictions arising from the possibly negative collateral effects of this policy on the Ecuadorian side of the border. This variation is used to estimate the effect of spraying on coca cultivation by regression discontinuity around the 10 km threshold and by conditional differences in differences. The results suggest that spraying one additional hectare reduces coca cultivation by 0.022 to 0.03 hectares; these effects are too small to make aerial spraying a cost-effective policy for reducing cocaine production in Colombia
The war on illegal drugs in producer and consumer countries : a simple analytical framework by Daniel Mejia( Book )

9 editions published between 2008 and 2011 in English and held by 23 WorldCat member libraries worldwide

This paper develops a model of the war against illegal drugs in both producer and consumer countries. The paper studies the trade-off faced by the government of the drug consumer country between prevention policies (aimed at reducing the demand for drugs) and enforcement policies (aimed at reducing the production and trafficking of drugs), and shows how the optimal allocation of resources between these two alternatives depends on the key parameters of the model. We use available data for the war on drugs in Colombia, and against consumption in the U.S., to calibrate the unobservable parameters of the model, such as the price elasticity of demand for cocaine; the effectiveness of prevention and treatment policies; and the relative effectiveness of interdiction efforts
Unequal opportunities and human capital formation by Daniel Mejia( Book )

4 editions published between 2005 and 2006 in English and held by 11 WorldCat member libraries worldwide

This paper develops a tractable, heterogeneous agents general equilibrium model where individuals have different endowments of the factors that complement the schooling process. The paper explores the relationship between inequality of opportunities, inequality of outcomes, and efficiency in human capital formation. Using numerical solutions we study how the endogenous variables of the model respond to two different interventions in the distribution of opportunities: a mean-preserving spread and a change in the support. The results suggest that a higher degree of inequality of opportunities is associated with lower average level of human capital, a lower fraction of individuals investing in human capital, higher inequality in the distribution of human capital, and higher wage inequality. In other words, the model does not predict a trade-off between efficiency and equality of opportunity in human capital formation
The pharmacological channel revisited : alcohol sales restrictions and crime in Bogota by Joao M. P. De Mello( )

6 editions published between 2012 and 2013 in English and held by 9 WorldCat member libraries worldwide

This paper attempts to evaluate the impact on crime of the restriction of late-night alcohol sales in Bogota and quantify the causal effect of problematic alcohol consumption on different crime categories. It is found that the restriction reduced deaths and injuries in car accidents and batteries. The results are stronger in areas where the restriction was actually binding and are highly heterogeneous depending on the number of liquor stores restricted at the block level. Finally, the paper measures the impact of the restriction on alcohol consumption (the first stage, or mechanism), and quantifies the causal pharmacological impact of alcohol consumption on crime using the restriction as an instrument for problematic alcohol consumption (the second stage). The results indicate that a one standard deviation (s. d.) increase in problematic alcohol consumption increases deaths and injuries in car accidents by 0. 51 s. d and 0. 82 s. d. respectively, and batteries by 1. 27 s. d.1
The war on illegal drug production and trafficking : an economic evaluation of Plan Colombia by Daniel Mejia( Book )

4 editions published between 2008 and 2011 in English and Spanish and held by 8 WorldCat member libraries worldwide

A large amount of resources have been spent on the "war on drugs" in Colombia under the program "Plan Colombia." However, the amount of cocaine reaching consumer countries remains relatively stable after seven years, and the price of cocaine at different stages has not risen. Thus policies such as this one, aimed at reducing the amount of drugs reaching consumers by curtailing production and trafficking, have been relatively ineffective. The first independent evaluation of the anti-drug policies implemented under Plan Colombia, The War on Illegal Drug Production and Trafficking: An Economic Evaluation of Plan Colombia evaluates the costs, efficiency, effectiveness, and future prospects of the war against illegal drug production and trafficking under Plan Colombia. The results from this paper should help policymakers shape more effective (and less costly) anti-drug policies and, hopefully, encourage future research in order to evaluate the costs and benefits of alternative policies, such as demand side controls (treatment and prevention policies) or the legalization (with the appropriate controls) of illegal drugs. The War on Illegal Drug Production and Trafficking is published by Universidad de los Andes Centro de Estudios sobre Desarrollo Economico (Center of Studies on Economic Development), a grantee of the Open Society Institute
