In settings such as investing for retirement or choosing a drug plan, individuals typically face a large number of options. In this paper, we analyze how the size of the choice set influences which alternative is selected. We present both laboratory experiments and field data that suggest larger choice sets induce a stronger preference for simple, easy-to-understand options.
In the customer expectations arena, relatively little attention has been paid to the impact on expectations of variation in cultural variables unique to a country. Here the authors focus on one country, India, and a major cultural influence there — the extent of belief in karma. Prior research in the United States suggests that disconfirmation sensitivity lowers expectations. Here the authors examine whether belief in karma and, consequently, having a long-term orientation, counteracts the tendency to lower expectations in two studies that measure and prime respondents' belief in karma.
We develop a methodology for the measurement of the parameters of cumulative prospect theory and time discounting models based on tools from the preference measurement literature. These parameters are typically elicited by presenting decision makers with a series of choices between hypothetical alternatives, gambles or delayed payments. We present a method for adaptively designing the sets of hypothetical choices presented to decision makers, and a method for estimating the preference function parameters which capture interdependence across decision makers as well as response error.
Suresh Sundaresan offers several insights on the development of financial markets in Asia and the Pacific. First, financial market development in the region should take account of the large number of households who are effectively unbanked, given the potential for positive feedback effects between financial markets, economic growth and stability. Second, there is a need for fundamental banking reforms of capital structures and liquidity sources to mitigate bankruptcy risks, as well as the cost to taxpayers of insolvency and bailouts.
Most studies of word-of-mouth (WOM) in marketing have concentrated either on aggregate outcomes (e.g., new product diffusion) or on the transmission process (i.e., "talking" or "sending" information). This paper instead focuses on the reception process at the individual level (i.e., "listening" to information), and addresses two questions: what makes people listen to WOM, and what are the drivers of the type and extent of WOM impact on recipients' brand attitudes and purchase intentions?
Recent years have seen extensive investigation of the information aggregation properties of prediction markets. However, relatively little is known about conditions under which a market will aggregate the private information of rational risk averse traders who optimize their portfolios over time. We consider a market model involving finitely many informed risk-averse traders interacting with a market maker. Our main result identifies a basic smoothness condition on the price in the market that ensures information will be aggregated.
We document the market response to an unexpected announcement of proposed sales of government-owned shares in China. In contrast to the "privatization premium" found in earlier work, we find a negative effect of government ownership on returns at the announcement date and a symmetric positive effect in response to the announced cancellation of the government sell-off.
