Rigorously testing multialternative decision field theory against random utility models
Cognitive models of decision making aim to explain the process underlying observed choices. Here, we test a sequential sampling model of decision making, multialternative decision field theory (MDFT; Roe, Busemeyer, & Townsend, 2001), on empirical grounds and compare it against 2 established random utility models of choice: the probit and the logit model. Using a within-subject...

A hierarchical Bayesian model of the influence of run length on sequential predictions
Two models of how people predict the next outcome in a sequence of binary events were developed and compared on the basis of gambling data from a lab experiment using hierarchical Bayesian techniques. The results from a student sample (N = 39) indicated that a model that considers run length (“drift model”)—that is, how often the same event has previously occurred in a row—provided a...

Genetic influences on dietary variety - Results from a twin study
The heritability of variety seeking in the food domain was estimated from a large sample (N = 5,543) of middle age to elderly monozygotic and dizygotic twins from the “Virginia 30,000” twin study. Different dietary variety scores were calculated based on a semi-quantitative food choice questionnaire that assessed consumption frequencies and quantities for a list of 99 common foods....

Illusionary pattern detection in habitual gamblers
Does problem gambling arise from an illusion that patterns exist where there are none? Our prior research suggested that “hot hand,” a tendency to perceive illusory streaks in sequences, may be a human universal, tied to an evolutionary history of foraging for clumpy resources. Like other evolved propensities, this tendency might be expressed more stongly in some people than others,...

Change and status quo in decisions with defaults: the effect of incidental emotions depends on the type of default
Affective states can change how people react to measures aimed at influencing their decisions such as providing a default option. Previous research has shown that when defaults maintain the status quo positive mood increases reliance on the default and negative mood decreases it. Similarly, it has been demonstrated that positive mood enhances the preference for inaction. We extend...

The Strategist's Change - How successful CSOs transform their Companies : Key Findings of the Chief Strategy Officer Survey 2014
In a world where business parameters are constantly changing, where uncertainty and geopolitical instability are on the rise, successful corporate transformation is one of the most critical – and most difficult – tasks for the Chief Strategy Officer (CSO). Adjusting to new conditions, which in an age of digitalization and hypercompetition often has to happen in real time, is akin to...

Ant Local Search for Combinatorial Optimization
In ant algorithms, each individual ant makes decisions according to the greedy force (short term profit) and the trail system based on the history of the search (information provided by other ants). Usually, each ant is a constructive process, which starts from scratch and builds step by step a complete solution of the considered problem. In contrast, in Ant Local Search (ALS), each...

Margining in derivatives markets and the stability of the banking sector
We investigate the effects of margining, a widely-used mechanism for attaching collateral to derivatives contracts, on derivatives trading volume, default risk, and on the welfare in the banking sector. First, we develop a stylized banking sector equilibrium model to develop some basic intuition of the effects of margining. We find that a margin requirement can be privately and...

Liquidity Risk, Return Predictability, and Hedge Funds' Performance: An Empirical Study
This article analyzes the effect of liquidity risk on the performance of equity hedge fund portfolios. Similarly to Avramov, Kosowski, Naik, and Teo (2007),(2011), we observe that, before accounting for the effect of liquidity risk, hedge fund portfolios that incor- porate predictability in managerial skills generate superior performance. This outperfor-mance disappears or weakens...

Preferences for Truthfulness: Heterogeneity among and within Individuals
We conduct an experiment assessing the extent to which people trade off the economic costs of truthfulness against the intrinsic costs of lying. The results allow us to reject a type-based model. People's preferences for truthfulness do not identify them as only either "economic types" (who care only about consequences) or "ethical types" (who care only about...

Do Implicit Barriers Matter for Globalization?
Market liberalization may not result in full market integration if implicit barriers are important. We test this proposition for investable and non-investable segments of twenty- two emerging markets (EMs). We also measure the degree of integration for six major developed markets (DMs) as a meaningful benchmark. We find that while the DMs are close to fully integrated, both EM...

Combining Stocks and Flows of Knowledge: The Effects of Intra-Functional and Cross-Functional Complementarity
While previous research has mostly focused on either knowledge stocks or knowledge flows, our study is among the first to integrate these perspectives in order to shed light on the complementarity effects of different types of knowledge stocks and flows in the multinational corporation (MNC). This study investigates intra-functional as well as cross-functional complementarity effects...
