Political polarization and the size of government

In this article, we study the relationship between political polarization and public spending using the dispersion of self-reported political preferences as our measure of polarization. Political polarization is strongly associated with smaller government in democratic countries, but there is no relationship between polarization and the size of government in undemocratic countries. The results are robust to a large set of control variables, including gross domestic product per capita and income inequality.

Economic Influences on Moral Values

Abstract This paper extends standard consumer theory to account for endogenous moral motivation. Building on cognitive dissonance theory, I show how moral values are affected by changes in prices and income. The key insight is that changes in prices and income that lead to higher consumption of an immoral good also affect the moral values held by the consumer so that the good is considered less immoral. A preliminary empirical analysis based on the World Values Survey is consistent with the models predictions with respect to income.

Word Order Typology through Multilingual Word Alignment

With massively parallel corpora of hundreds or thousands of translations of the same text, it is possible to automatically perform typological studies of language structure using very large languag ...

The Effect of Competition on Physical Activity: A Randomized Trial

Abstract Recent literature in economics has highlighted that competition and symbolic awards can provide non-monetary incentives. In this paper, we report on a step contest that we carried out at a large Swedish workplace in order to test whether competition for symbolic awards can be used to promote physical exercise. Each individual was equipped with a pedometer and registered the number of steps daily during a four week period. Participants competed both in teams and individually and the winning team and individual received symbolic prizes. To evaluate the effect of the competition, we randomized teams into a control group and two treatment groups. We found that the step contest significantly increased both the fraction of subjects that completed the step contest and the number of steps. The number of steps was about 1,000 steps higher in the main treatment group than in the control group (an increase by about 10 percent). This is a conservative estimate as the dropouts on average walked fewer steps than individuals completing the study. In an additional treatment, we also included a daily step goal in the contest. The step goal had no additional significant effect on the number of steps, which may be due to the relatively low step goal used (7,000 steps per day).

Bayesian Word Alignment for Massively Parallel Texts

There has been a great amount of work done in the field of bitext alignment, but the problem of aligning words in massively parallel texts with hundreds or thousands of languages is largely unexplo ...

Generosity and Political Preferences

We test whether generosity is related to political preferences and partisanship in Canada, Sweden, the United Kingdom and the United States using incentivized dictator games. The total sample consists of more than 5,000 respondents. We document that support for social spending and redistribution is positively correlated with generosity in all four countries. Further, we show that donors are more generous towards co-partisans in all countries, and that this effect is stronger among supporters of left-wing political parties. All results are robust to the inclusion to an extensive set of control variables, including income and education.

Modelling the informativeness and timing of non-verbal cues in parent–child interaction

How do infants learn the meanings of their first words? This study investigates the informativeness and temporal dynamics of non-verbal cues that signal the speakers referent in a model of early w ...

Visual Iconicity Across Sign Languages : Large-Scale Automated Video Analysis of Iconic Articulators and Locations

We use automatic processing of 120,000 sign videos in 31 different sign languages to show a cross-linguistic pattern for two types of iconic form–meaning relationships in the visual modality. First, we demonstrate that the degree of inherent plurality of concepts, based on individual ratings by non-signers, strongly correlates with the number of hands used in the sign forms encoding the same concepts across sign languages. Second, we show that certain concepts are iconically articulated around specific parts of the body, as predicted by the associational intuitions by non-signers. The implications of our results are both theoretical and methodological. With regard to theoretical implications, we corroborate previous research by demonstrating and quantifying, using a much larger material than previously available, the iconic nature of languages in the visual modality. As for the methodological implications, we show how automatic methods are, in fact, useful for performing large-scale analysis of sign language data, to a high level of accuracy, as indicated by our manual error analysis.

Phrase-Based SMT for Finnish with More Data, Better Models and Alternative Alignment and Translation Tools

This paper summarises the contributions of the teams at the University of Helsinki, Uppsala University and the University of Turku to the news translation tasks for translating from and to Finnish. Our models address the problem of treating morphology and data coverage in various ways. We introduce a new efficient tool for word alignment and discuss factorisations, gappy language models and reinflection techniques for generating proper Finnish output. The results demonstrate once again that training data is the most effective way to increase translation performance.

How does communication affect beliefs in one-shot games with complete information?

This paper experimentally studies unilateral communication of intentions in eight different two-player one-shot normal form games with complete information. We find that communication is used both to coordinate and to deceive, and that messages have a significant impact on beliefs and behavior even in dominance solvable games. Nash equilibrium and cognitive hierarchy jointly account for many regularities, but not all of the evidence. Sophisticated sender behavior is especially difficult to reconcile with existing models.
