摘要：This paper develops a model of taxation with asymmetric information between the worker and the employer as well as between the worker and the tax collector. We show that if the informational asymmetry in the labour market is solved through signaling, implications for taxation are strong. Taxing the signal directly, as well as imposing a progressive tax on income, are both shown to have favourable welfare consequences locally. In contrast to the results obtained for the progressive income tax, ...

摘要：It is well-known that the Kaldor compensation test can be inconsistent in the sense that it leads to contradictory or cyclical recommendations in some situations. This paper shows that there is a close relationship between the consistency of this test and the rationalizability of choices from given utility possibilities sets. This observation suggests that if the Kaldor test is consistent, social decisions can be made using a social welfare ordering in the first place. Therefore, the informati...

摘要：We clarify and extend a number of sufficient conditions for the existence of a majority voting equilibrium on one-dimensional choice domains. These conditions, variously stated in the previous literature, all impose order restrictions on voter preferences (for instance, monotone marginal rates of substitution) which we show to imply or be equivalent to a general, ordinal version of the single-crossing condition. This simple property is economically intuitive and easily checked in applications....

摘要：Household survey data from the Cote d'Ivoire are used to examine the impact of public policies on child height, child weight for height and adult body mass index. Economic adjustment programs in the 1980s were accompanied by reduced availability and quality of health care services and increases in relative food prices. The health of Ivorians was probably adversely affected by these changes. Basic services, such as immunizations and having simple materials, such as common drugs, in stock is ass...

摘要：This paper analyses how the level of social protection is determined when its choice depends on political competition. First, this is done under autarky. Then the analysis is extended to take account of the existence of an international capital market. We show that social protection never increases under international competition and, in several circumstances, drastically decreases.
