Illusory Revenues: Tariffs in Resource-Rich and Aid-Rich Economies
Collier, Paul, Venables, Anthony J.
Where imports are financed predominantly by rents from resource extraction or aid, the revenue generated by tariffs is illusory. Revenue earned by the tariff is offset by a reduction in the real...
Ethnicity, Politics and Economic Performance
The paper investigates the effects of ethnic diversity on economic performance. Previous studies have found that diversity has various detrimental microeconomic effects, tending to reduce public...
Greed and Grievance in Civil War
We investigate the causes of civil war, using a new data set of wars during 1960-99. We test a `greed’ theory focusing on the ability to finance rebellion, against a`grievance’ theory focusing on...
Murder by Numbers: Socio-Economic Determinants of Homicide and Civil War
Deliberate killing is a common part of the defining features of both homicide and civil war. Often, the scale of killing is also similar: most countries have homicide rates that exceed the threshold...

Arne Bigsten, Paul Collier, Stefan Dercon, Marcel Fachamps, Bernard Gauthier, Jan Willem Gunning, ...
In this paper, we use firm-level panel data for the manufacturing sector in four African countries to estimate the effect of exporting on efficiency. Estimating simultaneously a production function...
Development effectiveness: what have we learnt?
We suggest that the 'poverty-efficiency' aid allocation is merely a benchmark guide if a donor lacks other information about the country and also the power to change or prevail over government...
AID, POLICY AND PEACE: REDUCING THE RISKS OF CIVIL CONFLICT
We analyze theoretically and empirically the effects of economic policy and the receipt of foreign aid on the risk of civil war. We find that aid and policy do not have direct effects upon conflict...

African Growth: Why a 'Big Push'?
Over the past 40 years Africa has stagnated while other developing countries have grasped growth opportunities. This process of divergence has turned Africa into the poorest region. Africa needs a...
Credit Constraints in Manufacturing Enterprises in Africa
Arne Bigsten, Paul Collier, Stefan Dercon, Marcel Fafchamps, Bernard Gauthier, Jan Willem Gunning, ...
We investigate the question of whether firms in Africa's manufacturing sector are credit constrained. The fact that few firms obtain credit is not sufficient to prove constraints, since certain firms...
The Role of the State in Economic Development: Cross-Regional Experiences.
The paper reviews two roles of the state: the provision of security and the regulation of economic activity. I show that in both respects until recently African governments provided a poor...
Anatomy of a Temporary Trade Shock: The Kenyan Coffee Boom of 1976-9.
Bevan, David, Collier, Paul, Gunning, Jan Willem
The coffee boom of 1976-9 was an archetypal temporary external shock. Using counterfactuals, we find that much of the windfall was saved, due to the private sector. However, the control regime...

Paradise Lost: The Costs of State Failure in the Pacific
Chauvet, Lisa, Collier, Paul, Hoeffler, Anke
Globally, state failure is hugely costly. We estimate the total cost of failing states at around US$276 billion per year. In this paper we apply our global framework and methodology to analyse the...
The Cost of Failing States and the Limits to Sovereignty
Chauvet, Lisa, Collier, Paul, Hoeffler, Anke
In this paper, we estimate the costs of state failure, both for the failing state itself and for its neighbours. In our analysis, the cost of failure arises from two distinct sources: organized...
Beyond greed and grievance: feasibility and civil war
Paul Collier, Anke Hoeffler, Dominic Rohner

Testing the neocon agenda: Democracy in resource-rich societies
Resource-rich countries have tended to be autocratic and also have tended to use their resource wealth badly. The neoconservative agenda of promoting democratization in resource-rich countries thus...
The political economy of state failure

Commodity Prices, Growth, and the Natural Resource Curse: Reconciling a Conundrum
Collier, Paul, Goderis, Benedikt
Currently, evidence on the ‘resource curse’ yields a conundrum. While there is much cross section evidence to support the curse hypothesis, time series analyses using vector autoregressive (VAR)...
