We analyze the economic impacts of policies supporting biodiesel production in Colombia, such as subsidies and
mandates for compulsory fuel mixtures. In the major biodiesel source being palm oil, we seek to establish the
impact of these policies on oil palm producer incomes, prices and production levels of crude palm oil (CPO)
and biodiesel, as well as the impacts on demand for land for oil palm plantation expansion.
We also calculate the so-called “deadweight costs”, to account for the social costs derived from the inefficiencies
of government interventions in the biodiesel markets. The analysis is done using a partial equilibrium models for
the two interrelated sectors, the production of palm oil and biodiesel, and the demand for new land needed to
cope with the additional palm oil needed. The model was calibrated for 2009 to simulate for the 2010–2020
period.
The results of the simulations reveal that the subsidies alone are themselves not effective tools to achieve the
government objectives defined in the Biofuels Program in Colombia.
Subsidies need to be complemented by increased blending mandates to ensure that palm cultivation and produc-
tion of biodiesel investments are profitable enough that producers would bet on such business. Additionally, we
find that producers of palm oil benefit most from subsidies in the short term; however, in the long-term it is the
biodiesel entrepreneurs who will appropriate the larger share of growth revenue of the entire production chain.
The social costs of the Biofuels Program are small in the short term, and represent only between 0.2% and 0.7% of
the tax expenditure. However, in the long term they would become significant, and would account for around
4.1% to 6.1% of the tax payers' expense.

1. Introduction
An analysis of the economic impacts of biodiesel promotion policies
is a topic that has been addressed in various countries and for different
raw materials (Arndt et al., 2009; Gardner, 2007; De Gorter and Just,
2007). Generally these studies seek to make the relationships between
business decisions of feedstock cultivation and industrial production
of biofuels and fuel consumption explicit, with the aim of determining
the effects of the various direct support instruments on the links in
the production chain, as well as in other markets for agricultural inputs,
food, land or fuels (Latruffe and Mouel, 2009). For example, the way in
which the establishment of mandatory blending not only increases the
demand for biodiesel, but also reflects in the agricultural markets, food,
land and fuel. Similarly, direct subsidies or tax exemption for biodiesel
can generate the conditions for biofuel production to be profitable, but
may create inefficiencies and welfare costs for society, more commonly
known as “deadweight losses” (Tirole, 1988). All these policy decisions
have impacts on the use and conversion of land, CO
2
emissions and on
the income of the different players in the sector. Such aspects need to
be estimated in order to assess the benefits and costs of public policies.
In recent years, significant progress has been made in refining
the tools to analyze the impacts of policies promoting biofuels.
Kretschmer and Peterson (2008) conducted a detailed review of the
various options for economic modeling of biofuels. Among these tools,
the computable general equilibrium models have been used intensively,
because these models can examine the impacts of policies and exoge-
nous shocks globally, taking into consideration all the interactions
between the various markets and agents (Hosoe et al., 2010).
In the general equilibrium model of the GTAP-E version, Woltjer
et al. (2007) explicitly represents the use of cereals, vegetable oils and
sugar cane as raw materials for the production of biofuels in a multi-
level structure of the oil industry. This allows analyzing the policies of
tax exemption and obligatory blending mandates as exogenous in-
creases of the share of biofuels (Woltjer et al., 2007). Reilly and
Paltsev (2008) used a computable general equilibrium model to esti-
mate the global land area needed to produce the biofuels required to
