This paper reviews a number of criticisms made of the World Model. These criticisms suggest substantially greater parameter change than allowed by the original studies. When this is done, the results change, and the basic behaviour mode can exhibit , depending on the parameter values, collapse,...

What impact do taxes and public spending have on income distribution? The sanguine conclusion that government budgets take from the rich and give to the poor stems largely from the persistent assumption of neutral expenditure incidence. Recently, Aaron and McGuire outlined the basis for a new...

Results of U.S. survey of attitudes toward government were recently published. Respondents were asked whether spending on various government programs should be increased or cut. A similar set of questions were asked a decade ago. Comparisons reveal preferences for various public goods have...

An extension to a two-consumer bargaining model is suggested. A key role is played by the nature and extent...
