We investigate biases in product valuation and usage decisions that arise when consumers consider a new generation of a product that offers an expanded set of capabilities of uncertain value. Two experiments using a novel computer game show evidence of a : Participants display a high willingness...

Optimism bias is inconsistent with the independence of decision weights and payoffs found in models of choice under risk and uncertainty, such as expected utility theory, subjective expected utility, and prospect theory. We therefore propose an alternative model of risky and uncertain choice...

This paper is concerned with project level outcomes of 10 large transport projects spread over eight countries that had benefited from EU Cohesion and ISPA funding. These are analysed within a cost benefit analysis framework with comparisons being made between the ex ante and ex post cost...

We examine the impact of managerial optimism on the inclusion of performance-pricing provisions in syndicated loan contracts (PSD). Optimistic managers may view PSD as a relatively cheap form of financing given their upwardly biased expectations about the firm’s future cash flow. Indeed,...

Forecasters often predict continued rapid economic growth into the medium and long term for countries that have recently experienced strong growth. Using long-term forecasts of economic growth from the IMF/World Bank staff Debt Sustainability Analyses for a panel of countries, we show that the...

Purpose One of the major challenges for any project is to prepare and develop an achievable baseline schedule and thus set the project up for success, rather than failure. The purpose of this paper is to explore and investigate research outputs in one of the major causes, optimism bias, to...

Purpose – Drawing on mainstream arguments in the literature, the paper presents a coherent and holistic view on the causes of cost overruns, and the dynamics between cognitive dispositions, learning and estimation. A cost prediction model has also been developed using data mining for...

The outcome of pursuing an upper or post-secondary education degree is uncertain. A student might not complete a chosen degree for a number of reasons, such as insufficient academic preparation or financial constraints. Thus, when considering whether to invest in post-secondary education,...
