Winners in the spotlight: Media coverage of fund holdings as a driver of flows

We show that media coverage of mutual fund holdings affects how investors allocate money across funds. Fund holdings with high past returns attract extra flows, but only if these stocks were recently featured in the media. In contrast, holdings that were not covered in major newspapers do not affect flows. We present evidence that media coverage tends to contribute to investors? chasing of past returns rather than facilitate the processing of useful information in fund portfolios. Our evidence suggests that media coverage can exacerbate investor biases and that it is the primary mechanism that makes fund window dressing effective.     

Estimation of the public benefits of urban water supply improvements in Ethiopia: a choice experiment

Improving existing drinking water supply services in developing countries depends crucially on available financial resources. Cost recovery rates of these services are typically low, while demand for more reliable services is high and rapidly growing. Most stated preference-based demand studies in the developing world apply the contingent valuation method and focus on rural areas. This study examines household Willingness to Pay (WTP) for improved water supply services in a choice experiment in an urban area in Ethiopia, a country with the lowest water supply coverage in Sub-Saharan Africa. The design of the choice experiment allows estimation of the value of both drinking water supply reliability and safety. The estimated economic values can be used in policy appraisals of improved supply investment decisions. Despite significant income constraints, households are willing to pay up to 80% extra for improved levels of water supply over and above their current water bill. Women and households living in the poorest part of the city with the lowest service levels value the improvement of water quality most. As expected, also averting behaviour and expenditures play an important role.     

TECHNOLOGICAL INNOVATION AND EMPLOYMENT IN DERIVED LABOUR DEMAND MODELS: A HIERARCHICAL META‐REGRESSION ANALYSIS

The effect of technological innovation on employment is of major concern for workers and their unions, policy makers and academic researchers. We meta‐analyse 570 estimates from 35 primary studies that estimate a derived labour demand model. We contribute to existing attempts at evidence synthesis by addressing the risks of selection bias and that of data dependence in observational studies. Our findings indicate that: (i) hierarchical meta‐regression models are sufficiently versatile for addressing both selection bias and data dependence in observational data; (ii) innovation's effect on employment is positive but small and highly heterogeneous; (iii) only a small part of residual heterogeneity is explained by moderating factors; (iv) selection bias tends to reflect preference for upholding prevalent hypotheses on the employment effects of process and product innovations; (v) country‐specific effect‐size estimates are related to labour market and product market regulation in six OECD countries in a U‐shaped fashion; and (vi) OLS estimates reflect upward bias whereas those based on time‐differenced or within estimators reflect a downward bias. Our findings point out to a range of data quality and modelling issues that should be addressed in future research.     

Is households’ risk attitude robust to different experimental payoffs?

We compared risk attitudes among rural people in Tanzania and Kenya using an experimental design where payoffs were defined and quantified in maize and milk production. About 42% of the sample revealed different risk attitude between the two payoff types. The difference was mainly explained by household livelihood strategy, geographical location and ethnicity. Hence, appropriate pay-off metrics differ across contexts and different metrics may provide noncomparable results that does not reflect intrinsic risk attitude.     

Panel estimates of a two-tiered earnings frontier

This paper uses panel data to estimate a two-tiered instead of a one-tiered frontier model. The innovation is to develop a two-step maximum likelihood procedure yielding consistent estimates of inefficiency, while at the same time accounting for heterogeneity. The model is applied by estimating a ‘two-tiered’ earnings function to obtain indices of worker and firm incomplete labour market wage information using panel data from the Panel Study of Income Dynamics (1969–84). The estimation preserves the traditional quadratic age-earnings profile, but measures the extent to which employers often pay more than necessary to hire a worker (incomplete employer information), while at the same time, employees often accept wages less than they could otherwise command (incomplete employee information). The results indicate that employees acquire less information than employers. © 1996 John Wiley & Sons, Ltd.     

Survival of the fittest: Technical assistance,survival and growth of small businesses and implications for public policy

Concerns about the value of government programs that provide management and technical assistance have been the subject of debate among researchers and policymakers. Based on an analysis of a multiyear survey sponsored by the U.S. Small Business Administration's Office of Entrepreneurial Development, we examine the relationship between managerial and technical assistance and firm survival, as well as the relationship between the characteristics of technical assistance and financial and employment growth. Overall, findings suggest that managerial and technical assistance have a positive effect on both survival and growth, but these effects depend on the size of the firm, characteristics of the counseling experience, as well as age and other demographic differences. Implications for public policy are discussed.     

EFFECTS OF NON-PRICE EXPORT PROMOTION: SOME EVIDENCE FOR COTTON*

An Annington-type trade model is estimated to determine the effects of government-subsidized export promotion on the demand for U.S. cotton in the Pacific Rim. Results show a significant relationship between promotion expenditures and U.S. market share in four of the six countries examined. One of the two countries exhibiting a non-significant effect had very low promotion expenditures, suggesting that a minimal level of funding may be necessary to achieve a market response. The hypothesis that export promotion has a carryover period lasting beyond one year in general is supported by the data. The question of the economic impacts of export promotion on domestic producers and taxpayers must await additional research.     

Economic and fiscal impact analysis of energy development projects: Coal liquefaction in the Illinois Basin

This paper addresses the problem of anticipating the local economic, demographic and fiscal impacts occurring from the siting of coal liquefaction facilities in the Illinois Basin. This region (primarily western Kentucky) will contain some of the most ambitious liquefaction projects in the U.S., yet no comprehensive method for the estimation of these impacts currently exists. It is suggested that the solution might lie with the development of an integrated econometric impact evaluation model. The potential economic, demographic and fiscal impacts of these projects are also described, preliminary analyses using existing economic impact assessment methods are presented, and certain policy analysis applications are highlighted.
