1. Effects and Value of Verifiable Information in a
Controversial Market: Evidence from Lab Auctions of
Genetically Modified Food
Rousu, Matthew

Shogren, Jason F.
Tegene, Abebayehu
Food products containing genetically modified (GM) ingredients
have entered the market over the past decade. The biotech
industry and environmental groups have disseminating conflicting
private information about GM foods. This paper develops a unique
methodology for valuing independent third-party information in
such a setting and applies this method to consumers?
willingness to pay for food products that might be GM. Data are
collected from real consumers in an auction market setting with
randomized information and labeling treatments. The average value
of third-party information per lab participant is small, but the
public good value across U.S. consumers is shown to be quite
large.

2. The income distributional consequences of agrarian tariffs in
Sweden on the eve of World War I
Bohlin, Jan (Department of Economic History, School of
Business, Economics and Law, G?teborg University)
After 1870 Swedish agriculture was transformed in the direction
of more animal husbandry. Small farmers in particular specialized
in animal produce. Yet, agricultural protectionism primarily
served the interest of large landowners specializing in bread-
grain production. The paper explores the impact of agrarian
tariffs on the factor rewards of landowners, capitalists and
workers. Landowners predictably benefited from agrarian tariffs,
the more so if they specialized in bread-grain, as did rural
workers. With an integrated ruralurban labour market real incomes
of urban workers would have come under pressure if agrarian
tariffs had been dismantled while capitalists would have been
little affected. <p>

3. Productivity Growth and Convergence in Crop, Ruminant and Non-
Ruminant Production: Measurement and Forecasts
Ludena, Carlos
Hertel, Thomas
Preckel, Paul
Foster, Kenneth
Nin Pratt, Alejandro
There is considerable interest in projections of future
productivity growth in agriculture. Whether one is interested in
the outlook for global commodity markets, future patterns of
international trade, or the interactions between land use,
deforestation and ecological diversity, the rate of productivity
growth in agriculture is an essential input. Yet solid
projections for this variable have proven elusive - particularly
on a global basis. This is due, in no small part, to the
difficulty in measuring historical productivity growth. The
purpose of this paper is to report the latest time series
evidence on total factor productivity growth for crops, ruminants
and non-ruminant livestock, on a global basis. We then follow
with tests for convergence amongst regions, providing forecasts
for farm productivity growth to the year 2040. The results
suggest that most regions in the sample are likely to experience
larger productivity gains in livestock than in crops. Within
livestock, the non-ruminant sector is expected to continue to be
more dynamic than the ruminant sector. Given the rapid rates of
productivity growth observed recently, non-ruminant and crop
productivity in developing countries may be converging to the
productivity levels of developed countries. For ruminants, the
results show that productivity levels may be diverging between
developed and developing countries.

4. The Role of Global Land Use in Determining Greenhouse Gases
Mitigation Costs
Hertel, Thomas
Lee, Huey-Lin
Rose, Steven
Sohngen, Brent
This paper develops a CGE model with unique regional land types
and detailed non-CO2 GHG emissions which it uses to analyze the
potential for reductions in land-based greenhouse gas emissions
as well as forest sequestration. In our global, general
equilibrium analysis of carbon taxation, we find that forest
carbon sequestration is the dominant means for global GHG
emissions reduction in the land using sectors. However, when
compared to the rest of the world, emissions abatement in the US
comes disproportionately from agriculture, and, within
agriculture, disproportionately from reductions in fertilizer-
related emissions (primarily in maize production). In the world
as a whole, agriculture-related mitigation comes predominantly in
reduced methane emissions from ruminant livestock, which is
followed in relative importance by reductions in methane
emissions from paddy rice. We also find significant linkages
between emissions in one region and mitigation in another (i.e.
leakage). For example, in the US agriculture, abatement potential
is cut in half when we move from a national tax to a global
carbon tax. This is a consequence of the strong export
orientation of US agriculture, which responds to reduced
production in the rest of the world by increasing its own
production and hence emissions.

5. Analysis of the socio-economic impact of the tobacco CMO
reform on italian tobacco sector
F. Arfini
M. Donati
D. Menozzi
The Tobacco CMO (Common Market Organization) is involved in a
intense debate between the European tobacco industry and those
who are against to a crop whose transformed product is dangerous
to the health. European institutions have shown a strong interest
in this complex issue introducing two Reforms (1992 and 1998) and
one revision in 2004. This paper aims to analyse and investigate
the socio-economic impact of the tobacco CMO Reform of 2004 in
Italy, across the scenarios proposed by the EC Commission (2004),
both on the tobacco production and processing sector. The
considered socio-economic indicators are harvested surfaces, farm
income and overall employment, while the sample of farms used in
this research belong to the FADN?Italy sample.

6. Protectionism, agricultural prices and relative factor
incomes: Sweden?s wage-rental ratio, 1877-1926
Bohlin, Jan (Department of Economic History, School of
Business, Economics and Law, G?teborg University)
Larsson, Svante (Department of Economic History, School of
Business, Economics and Law, G?teborg University)
Trends in wage-rental ratios have figured prominently in the
recent literature on factor price convergence and globalisation
in the late nineteenth century. In that literature Sweden has
been described as a free trade country whose wage-rental ratio
exhibited a distinguished upward trend before World War I. This
article presents a new series of land prices which indicates an
increase in land rentals and an evolution of the wage-rental
ratio more in line with other European protectionist countries.
We explore the determinants of the Swedish wage-rental ratio and
assess the relative importance of protectionism and the change in
the product mix from arable to animal products in Swedish
agriculture. <p>

7. Checkerboards and Coase: Transactions Costs and Efficiency in
Land Markets
Randall Akee (IZA Bonn and Harvard University)
The Coase theorem emphasizes the role transactions costs play in
efficient market outcomes. We document inefficient outcomes, in
the presence of a transactions cost, in southern California land
markets and the corresponding transition to efficient outcomes
after the transactions cost is eliminated. In the late 1800s,
Palm Springs, CA was evenly divided, in a checkerboard fashion,
and property rights assigned in alternating blocks to the Agua
Caliente tribe and a non-Indian landowner by the US Federal
government. Sales and leasing restrictions on the Agua Caliente
land created a large transactions cost to development on those
lands; consequently, we observe very little housing investment.
Non-Indian lands provide a benchmark for efficient outcomes for
the Agua Caliente lands. Once the transactions cost for Agua
Caliente lands was removed, there is a convergence between
American Indian-owned and non Indian-owned lands in both the
number of homes constructed and the value of those homes.

8. Resource Curse in Reverse: The Coffee Crisis and Armed
Conflict in Colombia.
Oeindrila Dube (Kennedy School of Government, Harvard
Uinversity)
Juan F. Vargas (Department of Economics, Royal Holloway,
University of London and IQSS, Harvard University.)
Between 1998 and 2003 production increases in Brazil and Vietnam
drove down the price of coffee by 73 percent in global markets,
triggering the "international coffee crisis". We examine the
effect of this exogenous price fall on Colombia's civil war,
exploring whether politically-motivated violencee presented
different dynamics in the coffee-growing regions relative to the
non-coffee regions, during the pre-crisis and crisis periods.
Using a difference-in-difference framework, we find causal
evidnece that the steep decline in coffee prices substantially
increased both the incidence and intensity of Colombia's civil
war. We also propose a simple model linking the price shock to
violence and empirically examine the relative importance of three
potential mechanisms. While crop substitution from coffee to coca
explains very little of the variation, a disproportionate
increase in poverty in coffee areas is associated with greater
violence, as is a lower index of institutional development.

Differences

9. The success of ?Made in Italy?: an appraisal of quality-
based competitiveness in food markets
A. Ninni
M. Raimondi
M. Zuppiroli
The role of quality is often stressed in explaining the Italian
success in the international markets for consumption goods. Here
the proxy for a quality led domain is a strong price rigidity of
the demand in rich consuming countries for some food imports
coming from Italy. Our analysis does not support this idea, as
the usual price competition seems to be quite common also in very
detailed food markets. It suggests that the quality image of
Italian goods offers protection for some traditional products,
but that this protection is not strong enough to counteract price
competition. Then, the supposed incidence of the qualitatively
superior Italian products on the total of the Italian products is
probably overestimated.
