Welfare Impacts of the 1998 Financial Crisis in Russia and the Response of the Public Safety Net

We compare welfare indicators for a nationally-representative sample of Russians interviewed shortly after the 1998 financial crisis with data on the same people two years earlier. Both objective and subjective measures reveal a widespread, though not universal, deterioration in welfare. Current expenditures generally contracted more than incomes. Inequality fell. There were both gainers and losers at all levels. The safety net's response fell far short of what was needed to protect living standards, but it did help prevent even greater poverty. Even without better targeting, a modest expansion of the safety net could have prevented an increase in income poverty in the aftermath of the crisis.     

Stakeholder Values and Scientific Modeling in the Neuse River Watershed

In 1998, the North Carolina Legislature mandated a 30% reduction in the nitrogen loading in the Neuse River in an attempt to reduce undesirable environmental conditions in the lower river and estuary. Although sophisticated scientific models of the Neuse estuary exist, there is currently no study directly relating the nitrogen-reduction policy to the concerns of the estuarine system's stakeholders. Much of the difficulty lies in the fact that existing scientific models have biophysical outcome variables, such as dissolved oxygen, that are typically not directly meaningful to the public. In addition, stakeholders have concerns related to economics, modeling, implementation, and fairness that go beyond ecological outcomes. We describe a decision-analytic approach to modeling the Neuse River nutrient-management problem, focusing on linking scientific assessments to stakeholder objectives. The first step in the approach is elicitation and analysis of stakeholder concerns. The second step is construction of a probabilistic model that relates proposed management actions to attributes of interest to stakeholders. We discuss how the model can then be used by local decision makers as a tool for adaptive management of the Neuse River system. This discussion relates adaptive management to the notion of expected value of information and indicates a need for a comprehensive monitoring program to accompany implementation of the model. We conclude by acknowledging that a scientific model cannot appropriately address all the stakeholder concerns elicited, and we discuss how the remaining concerns may otherwise be considered in the policy process.     

Excess Volatility and UK Investment Trusts

Abstract:   The issue of whether or not asset prices are more volatile than the underlying fundamentals is an empirical question with implications for market efficiency. Recent research suggests that the volatility of closed end fund returns in the USA is significantly higher than the returns on assets held by the funds. This has been attributed to noise trading as closed‐end fund shares are predominantly held by individual investors. This study demonstrates that UK investment trust returns exhibit similar excess volatility in spite of the prevalence of institutional investors. However, big investment trusts in terms of market capitalisation show greater excess volatility than small trusts. Although most of the excess volatility appears to be idiosyncratic, investor sentiment index is the most important variable associated with residual returns.     

The Theory-Practice Gap in Capital Budgeting: Evidence from the United Kingdom

We report the results of a survey of capital budgeting techniques used by United Kingdom firms. Where possible, the evidence is combined with data collected over a 22 year period to provide a basis for the discussion of causes of trends. We observe that there has been a substantial narrowing of the theory-practice gap in the use of project appraisal methods. The gap has also narrowed in other areas: the analysis of risk, inflation adjustment, capital budget preparation, WACC calculation and post-auditing. However, there are other elements of capital budgeting theory, e.g. probability and beta analysis which have been adopted by very few practising managers. We also discuss non-economic projects, capital rationing and hurdle rates.
