Axiomatic bargaining theory (e.g., Nash's theorem) is static. We attempt to provide a dynamic justification for the theory. Suppose a Judge or Arbitrator must allocate utility in an (infinite) sequence of two-person problems; at each date, the Judge is presented with a utility possibility set in...

This paper studies the impact of employment subsidies in a simple macroeconomic model with imperfect competition and unemployment due to wage rigidity. COmputed with a simple formula that is robust to the specification of imperfect competition and wage rigidity, subsidies can make an economy...

The paper considers the problem of comparing income distributions for heterogeneous populations. Following Atkinson and Bourguignon (1987), we divide the population in different groups of needs and evaluate the social welfare with a utilitarian function. By considering the Generalized...
