THE WELFARE EFFECTS OF FOREIGN CAPITAL INFLOW WITH TARIFF-RIDDEN AND QUOTA-RESTRICTED IMPORTS*

The welfare effects of foreign capital inflow and changes in the foreign price and tariff rate of a tariff-ridden imported good are considered for a small country for both 3 times 2 and 3 times 3 trade models with a quota-restricted imported good (whose special case is a nontraded good). For the 3 times 2 model, foreign capital inflow does not affect home welfare when there is no tariff on imports, but it harms the home country if a tariff is imposed on the imports to the extent that the tariff-ridden imported good is more capital intensive than the exported good. On the other hand, for the 3 times 3 model the foreign-capital inflow benefits the home country if the tariff rate is below a certain level under the analogous capital-intensity assumptions. The welfare effects of changes in the foreign price of the tariff-ridden good and its tariff rate remain the same for both models.     

TESTING THE SEQUENTIAL LOGIT MODEL AGAINST THE NESTED LOGIT MODEL*

In this paper, we show that the sequential logit (SL) model, in which a choice process is characterized as a sequence of independent multinomial logit models, is a limiting case of the nested logit (NL) model. For testing the SL model against the NL model, we propose Wald, likelihood ratio and Lagrange multiplier tests after suitably reparameterizing the NL model. It is found that when the NL model parameters are “weakly identified”, the Wald test severely underrejects the true model, whereas the sizes of the LR and LM tests are not significantly affected.     

THE INFLUENCE OF TYPE OF HIGH SCHOOL ATTENDED ON UNIVERSITY PERFORMANCE*

It is widely reported that the main determinant of success at university is the score on university entrance exams. Recent studies have argued that the outcomes at university also differ according to the type of high school attended. This paper examines the impact of attending a non‐Government school on the marks of first‐year university students. Non‐Government school students are found to have lower marks at university than Government school students, with the mark differential being slightly larger for those who do not perform well at tertiary study. The main factors influencing the size of the gap between the university marks of students from Government and non‐Government schools are university entrance exam results and attendance at same‐sex high schools.     

UNCERTAINTY AND THE THEORY OF MARK-UP PRICING

This paper examines the role of demand uncertainty in influencing a firm's mark-up pricing decision. With no uncertainty the marginalist approach represents this mark-up as inversely and solely determined by the elasticity of demand. Here it is shown that the introduction of uncertainty does not alter this simple dependency for a risk neutral firm. For a risk averse firm, however, the mark-up is shown to depend on a range of factors, including the level of fixed and variable costs and the level of expected demand. It is argued that such variability of margin is more in keeping with observed behaviour.     

DEPRIVATION,INEQUALITY AND WELFARE*

Welfare ranking of income distributions involves a trade‐off between equity and efficiency. A person's feeling of deprivation about higher incomes may be of a relative or absolute type. We consider an intermediate notion of deprivation, a convex mix of relative and absolute deprivations. We then look at the problem of welfare ranking of income distributions when welfare increases under a globally equitable redistribution and under an income increase that keeps intermediate deprivation fixed. All deprivation indices can be regarded as inequality indices but the converse is not true. We also provide a numerical illustration of our results.     

MIGRATION,MEDICAL AID AND WELFARE*

This paper constructs a simple rural‐urban migration model that explicitly incorporates the interactions between the individual's migration decision, the risk of incurring an infectious disease and unemployment. We show that providing a subsidy for health investment in urban regions in the form of medical aid does not improve individual welfare. This is because it induces further urban migration, increases the risk of infection and unemployment, and offsets completely the positive cost‐reduction effect.     

INEQUALITY AND WELFARE IN EEC COUNTRIES *

Inequality and welfare comparisons are performed using simple and generalized Lorenz curves and a number of ranking criteria suggested by Shorrocks and Foster, Dardanoni and Lambert, and Davis and Hoy, on Family Expenditure Survey data of nine EEC countries. The highest levels of inequality are observed in Italy and Greece and the lowest in Denmark, Belgium and France, whereas welfare is found to be relatively low in Greece and Ireland and relatively high in Belgium and France.
