investment strategy and selection bias an equilibrium perspective on overoptimism
The American Economic Review, 2018Co-Authors: Philippe JehielAbstract:Investors of new projects consider the returns of implemented projects delivering the same impression, and invest if the empirical mean return exceeds the cost. The steady states of such economies result in suboptimal investment decisions due to the selection bias in the sampling procedure and the dispersion of impressions across investors. Assuming better impressions are associated with higher returns, investors assessments of their projects are overoptimistic, and there is overinvestment as compared with the rational benchmark. The presence of rational investors aggravates the overoptimism bias of sampling investors, thereby illustrating a Negative Externality imposed by rational investors.

investment strategy and selection bias an equilibrium perspective on overconfidence
Social Science Research Network, 2015Co-Authors: Philippe JehielAbstract:Prospective investors of new projects consider the returns of implemented projects with similar (observed) attributes and invest if the empirical mean return exceeds the cost. The steady states of such economies result in suboptimal investment decisions due to the selection bias in the sampling procedure. Assuming higher attributes are associated with higher returns, there is systematic overinvestment as compared with the Bayesian benchmark, thereby illustrating that selection bias may explain entrepreneurial overconfidence. Various extensions are considered to illustrate the Negative Externality that rational investors exert on other investors, the effect of correlation between the attributes considered by various investors, and how trading may be affected by the sampling procedure.

minimizing the Negative Externality from sachet water consumption in nigeria
Social Science Research Network, 2012Co-Authors: Nathaniel E Urama, Romanus E Ukwueze, Gladys C AnekeAbstract:Over the years, there has been a consistent increase in the production and use of plastic and sachet packaged products in Nigeria which results in a proportional increase in plastic and Nylon waste pollution in the environment. An earlier survey show that the introduction of sachet water in the country some years ago worsened the situation as it contributes to more than 60% of the sachet pollution. This study therefore tried to find out an efficient and sustainable means of collecting the used sachet water bags to minimize its Negative external impact on the environment. It was carried out using primary data collected through direct interview from a sample of 1500 individual in some selected states in the Country. The data was analyzed using descriptive statistics and Log-log regression model. The results of the analysis show that PPP method can be effective in managing the menace. Majority of the sampled individuals are of the opinion that a 100% PPP levy will be a sufficient motivation for sachet water users to return their used sachet water bags to the appropriate collection sites in return for their levy or for the trash pickers to collect them for an equivalent payment.
