Work disincentive effects of taxes: a reexamination of some evidence

Article Abstract:

The economic literature suggests that the recognition of taxes in the piecewise-linear estimation procedure generates various predictions of substitution and income effects. A newer study indicates that the enforcement of Slutsky conditions over a wide range of hours leads to the divergent estimates in the use of the piecewise-linear approach. The piecewise-linear approach still is an effective technique for evaluating labor supply and taxes. This approach can be enhanced by using a flexible hours-of-work specification and an expansion allowing for husband-and-wife labor supply decisions.

Institutional and intertemporal influences on the trade of developing countries

Article Abstract:

The characteristics of commodity markets present intertemporal considerations in the evaluation of trade policy. The regulations that determine the quotas of developed countries in restricting market entry introduce dynamic economic considerations into developing nations' decisions. These issues include the Sugar Protocol and the International Coffee Agreements. A model illustrates how countries dealing with trade policies such as these determine the amount they sell to the residual market and the quota market.

On the theory of piecemeal tariff reform: the case of pure imported intermediate inputs

Article Abstract:

The effects of pure imported intermediate inputs on piecemeal tariff reform were studied. The results obtained by James Meade, also called the concertina theorem, were studied in a model with a pure imported input. The results indicated that the concertina method of piecemeal tariff reform became less effective when imported inputs were present. Substitutability, which was required by the concertina method, was not consistent with the Rybczynski relationship when pure imported intermediate inputs were present.
