Poverty, Risk Aversion, and Path Dependence in Low-Income Countries: Experimental Evidence from Ethiopia

In most low-income countries, rural households depend on mixed rain-fed agriculture/livestock production, which is very risky. Due to numerous market failures, there are few ways to shift risks to third parties. The literature has focused on what determines the responses of households in such environments. Of special concern are path dependencies in which households experiencing failure are prone to further failure and potential poverty traps. This paper estimates levels and determinants of risk aversion in the highlands of Ethiopia. We find high risk aversion and evidence that constraints have important impacts on risk-averting behavior with perhaps significant implications for long-term poverty. The results also suggest the possibility of path dependence and offer insights into links between risk aversion and poverty traps.     

Environmental Liability and Privatization in Central and Eastern Europe: Toward an Optimal Policy

It has been estimated that the costs of remediating contaminated sites in Central and Eastern Europe (CEE) will be very high. These contingent environmental liabilities have emerged precisely at the time CEE countries are attempting to privatize their capital stocks, creating major challenges for privatization agencies. It is also generally agreed that an inadequate handling of these liabilities in the past has reduced sales of state-owned enterprises in Central and Eastern Europe.This paper uses an analytical model to identify optimal policies for minimizing the damage to privatization processes from environmental liabilities. Policy simulations are conducted which evaluate the effects of the use of liability indemnifications and environmental audits on privatization sales, prices and government revenues net of environmental costs. The major finding of the paper is that goals to mitigate the effects of environmental liability on privatizations and maximize government net revenues from privatization sales require equivalent environmental liability policies. Both goals require optimal provision of information and indemnifications to investors, and moreover it is found that the two policies are complementary rather than substitutes.     

Estimating returns to soil conservation adoption in the northern Ethiopian highlands

Land degradation in the form of soil erosion and nutrient depletion presents a threat to food security and sustainability of agricultural production in many developing countries. Governments and development agencies have invested substantial resources to promote soil conservation practices as part of an effort to improve environmental conditions and reduce poverty. However, limited rigorous empirical work has been done on the economics of soil conservation technology adoption. This article investigates the impact of stone bunds on value of crop production per hectare in low and high rainfall areas of the Ethiopian highlands using cross-sectional data from more than 900 households, with multiple plots per household. We have used modified random effects models, stochastic dominance analysis (SDA), and matching methods to ensure robustness. The parametric regression and SDA estimates are based on matched observations obtained from the nearest neighbor matching using propensity score estimates. This is important, because conventional regression and SDA estimates are obtained without ensuring that there actually exist comparable conserved and nonconserved plots on the distribution of covariates. We use matching methods, random effects, and Mundlak's approach to control selection and endogeneity bias that may arise due to correlation of unobserved heterogeneity and observed explanatory variables.
We find that the three methods tell a consistent story. Plots with stone bunds are more productive than those without such technologies in semi-arid areas but not in higher rainfall areas, apparently because the moisture conserving benefits of this technology are more beneficial in drier areas. This implies that the performance of stone bunds varies by agro-ecology type, suggesting the need for designing and implementing appropriate site-specific technologies.     

How Much Will It Cost to Join the Club? The Extra Costs of Approximating Lithuanian Environmental Laws with Those of the European Union

This paper presents estimates of costsassociated with approximating Lithuanianenvironmental protection legislation with thatof the European Union (EU). Lithuania is oneof twelve EU associate members in Central andEastern Europe that is currently preparing foraccession by approximating their legislationwith that of the EU. The costs of fifteen EUdirectives are considered and details are givenon four directives. Necessary investments maytotal Euro 1500 million by 2015 and the presentvalue of all annualized costs is expected to beabout Euro 2200 million. In 2015, annualized costsare estimated to be approximately Euro 500 million,but these costs are only part of the totalcosts of approximation. Non-environmentalcosts are not considered. Assuming a modestlyambitious average annual growth of GDP of 2.0%per year implies that approximation with thefifteen directives analyzed will cost roughly3.5% of GDP in 2015. This level of additional commitment to environmentalprotection is itself much higher than the 2.0%of GDP being spent on average by OECD countriesand suggests the possibility of a substantialeconomic burden on the Lithuanian economy. Public budgets and households are expected tocarry a substantial portion of this cost,because many directives are the responsibilityof national and local governments. Making theright choices that are expected to be part ofapproximation with the environmental acquis is likely to benefit from carefulcomparisons of costs and willingness to pay forthe environmental benefits of approximation.
