We propose a model where voters experience an emotional cost when they observe a firm that has displayed insufficient concern for other people's welfare (altruism) in the process of making high profits. Even with few truly altruistic firms, an equilibrium may emerge where all firms pretend to be kind and refrain from charging "abusive" prices to their customers. Our main result is that, as competition decreases, the set of parameters for which such pooling equilibria exist beomes smaller and firms are more likely to anger consumers. Regulation can increase welfare, for example, through fines (even if there are no changes in prices). We illustrate these gains in a monopoly setting, where regulation affects welfare through 3 channels (i) a reduction in monopoly price leads to the production ...

We study the correlation between a belief concerning individualism and a measure of luck in the US during the period 1983-2004. The measure of beliefs is the answer to a question related to whether the poor should be helped by the government or if they should help themselves, while the measure of luck is the share of the oil industry in the state's economy multiplied by the price of oil. The correlation is negative, suggesting that more reliance on luck is correlated with less individualism. We provide three short models that help interpret this correlation. One implication of this finding is that societies that depend heavily on oil, and perhaps natural resources more generally, will experience a heavier demand for government intervention. We argue that if a government cares about the imp...

We observe that countries where belief in the "American dream" (i.e., effort pays) prevails also set harsher punishment for criminals. We know from previous work that beliefs are also correlated with several features of the economic system (taxation, social insurance, etc). Our objective is to study the joint determination of these three features (beliefs, punitiveness and economic system) in a way that replicates the observed empirical patterns. We present a model where beliefs determine the types of contracts that firms offer and whether workers exert effort. Some workers become criminals, depending on their luck in the labor market, the expected punishment, and an individual shock that we call "meanness". It is this meanness level that a penal system based on "retribution" tries to dete...
