A production model is formulated for the Finnish metal product and machinery industry for studying energy crises-related structural changes. Two models are estimated: a partial static equilibrium model, where capital is treated as a fixed input in the short run, and a dynamic model, where...

The models in the literature on exchange-rate target zones imply a non-linear time series model for the exchange rate. We show how the parameters of such models can be estimated and develop Maximum Likelihood and Method of Simulated Moments estimators for the target zone model of Krugman (1991)....

Immigrant relative earnings estimates are sensitive to the choice of comparison point and the specification of earnings. Non-sample mean comparisons (Borjas, 1985) understate relative earnings. Simple earnings specifications (linear education, quadratic experience) overstate relative earnings...
