The Difference Between Saying and Doing: Comparing Subjective and Objective Measures of Effort Among Fifth Graders

The first goal of this study is to examine the capacity of prominent survey-based effort proxies to predict real effort provision in children. Do children who "talk the talk" of hard work also "walk the walk" and make costly effort investments? The second goal is to assess how objective and subjective effort measures are related under two conditions: intrinsic (nonincentivized) motivation and extrinsic (incentivized) motivation. We measure objective "real" effort using three tasks and subjective self-reported effort using four psychological characteristics (conscientiousness, need for cognition, locus of control and delay of gratification) to understand to what extent material incentives affect the cognitive effort of children with different self-reported personalities. Data stem from real-effort experiments carried out with 420 fifth grade students from primary schools in Madrid, Spain. We find that some of the subjective and objective effort measures are positively correlated. Yet the power of personality to predict real effort is only moderate, but greater and more so in the extrinsic than the intrinsic motivation condition. In particular, need for cognition and conscientiousness are the most relevant correlates of objective effort. Overall, we find there is a big difference between saying and doing when it comes to exerting effort, and this difference is even larger when there are no direct material incentives in place to reward effort provision

Carbon Policy Implementation: A Country-Level Analysis of Carbon Tax vs. Cap and Trade

Climate change is arguably the greatest issue faced by this generation. Mitigation requires an informed and motivated global effort in order to be effective. This paper examines the relationship between emissions from 1980-2020 along with relevant covariates, and carbon policy status, specifically a carbon tax and a cap and trade. An analysis of how the implementation of carbon policies impacts emissions helps to determine the most effective and efficient way to combat climate change. I first run a regression of covariates with emissions and find statistically significant factors that influence emissions: meat production, population, intellectual property charges, and infant deaths. I analyze policy implementation over time in relation to emissions and find with statistical significance that a decrease of 1 million tons of CO2 is associated with an increase in approximately 6 ± 3.150 years of a policy being implemented. Utilizing a linear comparison of carbon tax versus ETS, I find that emissions changes for countries with a cap and trade are 2.15% lower than countries with a carbon tax, which may suggest that it is a more effective carbon policy. Most recently, the COVID-19 pandemic lockdowns have led to record decreases in annual emissions for 2020. Based on a linear comparison, I determine that there was no statistical difference in emissions reductions throughout 2020 regardless of whether or not a country had a carbon policy implemented prior to the outbreak. Going forward, this paper calls for greater research attention on the impact of carbon policy implementation on emissions in order to best inform governments based on historical data and evidence towards choosing the most effective policy. Climate change is fundamentally time sensitive and our society cannot afford means of policy implementation that are ineffective or stagnant

Development and the interaction of enforcement institutions

We examine how institutions that enforce contracts between two parties, producers and consumers, interact in a competitive market with one-sided symmetric information and productivity shocks. We compare an informal enforcement mechanism, reputation, the efficacy of which is enhanced by consumers investing in “connectedness,” with a formal mechanism, legal enforcement, the effectiveness of which can be reduced by producers by means of bribes. When legal enforcement is poor, consumers connect more with one another to improve informal enforcement; in contrast, a well-connected network of consumers reduces producers’ incentives to bribe. In equilibrium, the model predicts a positive relationship between the the frequency of productivity shocks, bribing, and the use of informal enforcement, providing a physical explanation of why developing countries often fail to have efficient legal systems. Firm-level estimations confirm the partial equilibrium implications of the model

Strong, Bold, and Kind: Self-Control and Cooperation in Social Dilemmas

We develop a model relating self-control, risk preferences and conflict identification to cooperation patterns in social dilemmas. We subject our model to data from an experimental public goods game and a risk experiment, and we measure conflict identification and self-control. As predicted, we find a robust association between self-control and higher levels of cooperation, and the association is weaker for more risk-averse individuals. Free riders differ from other contributor types only in their tendency not to have identified a self-control conflict in the first place. Our model accounts for the data at least as well as do other models

How calibration committees can mitigate performance evaluation bias: An analysis of implicit incentives

While prior research on performance evaluation bias has mainly focused on the determinants and consequences of rating errors, we investigate how a firm can provide implicit incentives to supervisors to mitigate these errors via its calibration committee. We empirically examine the extent to which a calibration committee incorporates supervisors' evaluation behavior with respect to their subordinates in the performance evaluation outcomes, i.e., performance ratings and promotion decisions, for these supervisors. In our study, we distinguish between lack of skills and opportunism as two important facets of evaluation behavior, which we expect the calibration committee to address differently. Using panel data of a professional service firm, we show that supervisors' opportunistic behavior to strategically inflate subordinates' performance ratings is disciplined through a decrease in the supervisors' own performance rating, while the supervisors' skills to provide less compressed and thus more informative performance ratings is rewarded through a higher likelihood of promotion.Series: Department of Strategy and Innovation Working Paper Serie

Information Literacy Instruction in an English Capstone Course: A Study of Student Confidence, Perception, and Practice

An English professor and an instruction librarian at the University of New Hampshire at Manchester felt that the college\u27s new English Capstone course for majors provided a unique opportunity to assess the information literacy skill levels of graduating English majors. They therefore engaged in a three-year study to evaluate the IL competency of these students, to gauge their perceptions of library instruction provided during the Capstone course and throughout their academic careers, and to determine students\u27 confidence and self-efficacy with respect to these skills. The researchers sought to determine the ways in which the IL program for English majors effectively met established IL goals and to identify areas for improvement

CHORUS Deliverable 2.1: State of the Art on Multimedia Search Engines

Based on the information provided by European projects and national initiatives related to multimedia search as well as domains experts that participated in the CHORUS Think-thanks and workshops, this document reports on the state of the art related to multimedia content search from, a technical, and socio-economic perspective. The technical perspective includes an up to date view on content based indexing and retrieval technologies, multimedia search in the context of mobile devices and peer-to-peer networks, and an overview of current evaluation and benchmark inititiatives to measure the performance of multimedia search engines. From a socio-economic perspective we inventorize the impact and legal consequences of these technical advances and point out future directions of research
