Core competencies in advanced training: what supervisors say about graduate training

In an attempt to identify needed mental health skills, many professional organizations have or are in the process of establishing core competency standards for their professions. The AAMFT identified 128 core competencies for the independent practice of MFT. The aim of this study was to learn the opinions of AAMFT Approved Supervisors as to how well prepared postgraduate trainees are when compared to the core competencies. One hundred thirty-five AAMFT Approved Supervisors provided their perspectives on (a) which competencies are most commonly learned in MFT graduate programs, (b) how well the graduates have mastered these competencies, and (c) the level to which the supervisors need the competencies to be mastered prior to entering advanced training. Results suggest that a gap exists between the level of mastery that the postgraduate trainees exhibit and the level desired by supervisors. Implications are suggested for closing this gap.     

The Evolution of Cooperative Strategies for Asymmetric Social Interactions

How can cooperation be achieved between self-interested individuals in commonly-occurring asymmetric interactions where agents have different positions? Should agents use the same strategies that are appropriate for symmetric social situations? We explore these questions through the asymmetric interaction captured in the indefinitely repeated investment game (IG). In every period of this game, the first player decides how much of an endowment he wants to invest, then this amount is tripled and passed to the second player, who finally decides how much of the tripled investment she wants to return to the first player. The results of three evolutionary studies demonstrate that the best-performing strategies for this asymmetric game differ from those for a similar but symmetric game, the indefinitely repeated Prisoner’s dilemma game. The strategies that enable cooperation for the asymmetric IG react more sensitively to exploitation, meaning that cooperation can more easily break down. Furthermore, once cooperation has stopped, it is much more difficult to reestablish than in symmetric situations. Based on these results, the presence of asymmetry in an interaction appears to be an important factor affecting adaptive behavior in these common social situations.     

Avoiding the curves: Direct elicitation of time preferences

We propose and test a new method for eliciting curvature-controlled discount rates that are invariant to the form of the utility function. Our method uses a single elicitation task and obtains individual discount rates without knowledge of risk attitude or parametric assumptions about the form of the utility function. We compare our method to a double elicitation technique in which the utility function and discount rate are jointly estimated. Our experiment shows that these methods yield consistent estimates of the discount rate, which is reassuring given the wide range of estimates in the literature. We find little evidence of probability weighting, but in a second experiment, we observe that discount rates are sensitive to the length of the front-end delay, suggesting present bias. When the front-end delay is at least two weeks, we estimate average discount rates to be 11.3 and 12.2% in the two experiments.

FOOD AWAY FROM HOME AND CALORIC INTAKE: THE ROLE OF RESTAURANT MENU LABELING LAWS

We analyze whether local and state mandates to post calorie information on restaurant menus change the effect of consuming food prepared away from home (FAFH) on total caloric intake. Information on area demographics and the local food environment were used to construct a comparison group. For identification, we use differences in two days of dietary intake and timing variations in policy implementation. We find the effect of FAFH meals on total daily intake is reduced by 21 calories among adults and by 34 calories among young children for each year the mandate is in place. (JEL I12, I18, H75)     

Anticipating Regret: Why Fewer Options May Be Better

We study preferences over menus which can be represented as if the agent selects an alternative from a menu and experiences regret if her choice is ex post inferior. Since regret arises from comparisons between the alternative selected and the other available alternatives, our axioms reflect the agent's desire to limit her options. We prove that our representation is essentially unique. We also introduce two measures of comparative regret attitudes and relate them to our representation. Finally, we explore the formal connection between the present work and the literature on temptation.     

Weighted Distance Weighted Discrimination and Its Asymptotic Properties

While Distance Weighted Discrimination (DWD) is an appealing approach to classification in high dimensions, it was designed for balanced datasets. In the case of unequal costs, biased sampling, or unbalanced data, there are major improvements available, using appropriately weighted versions of DWD (wDWD). A major contribution of this paper is the development of optimal weighting schemes for various nonstandard classification problems. In addition, we discuss several alternative criteria and propose an adaptive weighting scheme (awDWD) and demonstrate its advantages over nonadaptive weighting schemes under some situations. The second major contribution is a theoretical study of weighted DWD. Both high-dimensional low sample-size asymptotics and Fisher consistency of DWD are studied. The performance of weighted DWD is evaluated using simulated examples and two real data examples. The theoretical results are also confirmed by simulations.
