We derive formulas for the optimal tariff rate in four theoretical models. We start with a model in which industries are competitive and then successively allow for: monopoly pricing by export industries, revenue-replacement costs and cold-shower effects. The theoretical formulas accurately...

Computable general equilibrium (CGE) models can be used to generate detailed forecasts of output growth for commodities/industries and thereby provide baselines from which to calculate the effects of policy changes. In this article, we assess a CGE forecasting method that has been applied in...

Payroll-tax thresholds make firms smaller than they would otherwise be and concentrate firms at just below threshold employment. We estimate the resulting dead-weight losses under perfect and monopolistic competition. Under monopolistic competition, the threshold-induced dead-weight loss in...

This paper describes historical and decomposition simulations undertaken for 1992-98 with a 500-sector computable general equilibrium model of the US. The historical simulation provides estimates of movements in unobservable technology and preference variables. The decomposition simulation...

A key question concerning labour-market programs is the extent to which they generate jobs for their target group at the expense of others. This effect is measured by displacement percentages. We describe a version of the MONASH model designed to quantify the effects of labour-market programs....
