Cognitive Ability and Paternalism [статья]
Опубликовано на портале: 04-11-2004Saint-Paul Gilles IZA Discussion Papers. 2002. No. 609.
This paper analyses the welfare effects of price restrictions on private contracting in a world where agents have a limited cognitive ability. People compute the costs and benefits of entering a transaction with an error. The government knows the distribution of true costs and benefits as well as that of errors. By imposing constraints on transaction prices, the government eliminates some that are on average inefficient--because the price signals that one of the parties has typically grossly overestimated its benefit from participation. This policy may increase aggregate welfare even though some of the transactions being blocked are actually efficient. The paper also studies the extent to which the use of private consultants with sufficient intelligence by people with limited intelligence may dominate government regulation.
Dependent Forms of Self-Employment in the UK: Identifying Workers on the Border between Employment and Self-Employment [статья]

We analyse the characteristics of workers who provide work on the basis of a civil or commercial contract, but who are dependent on or integrated into the firm for which they work. We argue that these dependent self-employed lose their rights under labour law, receive less favourable benefits from social security protection and are often beyond trade union representation and collective bargaining. Using data from the British Labour Force Survey we test two hypotheses: (1) Dependent self-employed workers are significantly different from both employees and (independent) self-employed individuals, thus forming a distinct group. (2) Dependent self-employed workers have lower labour market skills, less labour market attachment and, thus, less autonomy than self-employed workers. The data support our hypothesis that dependent self-employed workers are a distinct labour market group which differs from both employees and independent self-employed individuals. Men, older workers, those with low education and a low job tenure have greater odds of working in dependent self-employment than their counterparts. Our results suggest that dependent forms of self-employment are used by firms to increase labour flexibility.

Since the Middle Ages the Jews have been engaged primarily in urban, skilled occupations, such as crafts, trade, finance, and medicine. This distinctive occupational selection occurred between the seventh and the ninth centuries in the Muslim Empire and then it spread to other locations. We argue that this transition was the outcome of the widespread literacy among Jews prompted by an educational reform in the first century CE. Based on the growing nexus between education and Judaism in the first half of the millennium, we build a model in which Jewish men choose education, occupation, religion, and location. The model predicts that when urbanization expands (as it did in the Muslim Empire), Jews move to new cities due to their comparative advantage in urban, skilled occupations. Furthermore, before urbanization a proportion of Jewish farmers are predicted to convert to other religions. The predictions of the model regarding conversions, migrations, and reduction in the size of the Jewish population are consistent with the historical evidence about the first millennium provided by the historians. Hence, our study presents evidence for the long-term economic implications of changes in social norms.
In-Group Cooperation in a Hostile Environment: An Economic Perspective on Some Aspects of Jewish Life in (Pre-Modern) Diaspora [статья]

The demographic history of the Jews in the Middle Ages may be characterized by two main phenomena: i) a sharp drop in the number of Jews until the beginning of the modern period, due mainly to conversions; and, ii) early urbanization. Until now, these features have been analyzed as primarily resulting from persecution and restrictions initiated by the political and religious authorities in the host countries. Economic historians have recently proposed an explanation based on mandatory education in the Jewish tradition (Botticini and Eckstein, 2001). We propose a supplementary explanation based on the incentives to switch affiliation and/or location in a dual environment, where potential gains from in-group cooperation for the Jewish minority may well be offset by losses due to intergroup hostility. Our model generates the two results described above (i.e., a decrease in the total number of Jews, and their concentration in urban areas), without having to rely either on discrimination policies or on investment in human capital, as in previous research.

This paper documents the major features of Jewish economic history in the first millennium to explain the distinctive occupational selection of the Jewish people into urban, skilled occupations. We show that many Jews entered urban occupations in the eighth-ninth centuries in the Muslim Empire when there were no restrictions on their economic activities, most of them were farmers, and they were a minority in all locations. Therefore, arguments based on restrictions or minority status cannot explain the occupational transition of the Jews at that time. Our thesis is that the occupational selection of the Jews was the outcome of the widespread literacy prompted by a religious and educational reform in the first century ce, which was implemented in the third to the eighth century. We present detailed information on the implementation of this religious and educational reform in Judaism based on the Talmud, archeological evidence on synagogues, the Cairo Geniza documents, and the Responsa literature. We also provide evidence of the economic returns to Jewish religious literacy.

Краеугольным камнем существующих попыток реформировать немецкую систему здравоохранения путем внедрения частных схем страхования является предположение, что экономические стимулы играют важную роль при принятии решения о пользовании медицинскими услугами. Эта гипотеза проверяется на примере спроса на услуги госпиталей, что составляет наибольшую часть страховых расходов. В статье используются различные методы анализа данных по частоте обращений в больницы. В отличии от исследований, проводившихся в других странах, в данном случае не было выявлено существенного воздействия схем страхования на уровень госпитализации. Поэтому существующие попытки уменьшить расходы, полагаясь на поведение потребителей, вряд ли будут успешны.

This paper begins the synthesis of two currently unrelated literatures: the human capital approach to health economics and the economics of cognitive and noncognitive skill formation. A lifecycle investment framework is the foundation for understanding the origins of human inequality and for devising policies to reduce it.
