We show that, even with flexible domestic wages, international outsourcing may worsen the welfare of the home country and reduce the profits of all firms. If wages are rigid, outsourcing is welfare-improving if and only if the sum of the “trade creation” effect and the “exploitation effect” exceeds the “trade diversion” effect. A wage subsidy may improve welfare. We also extend the model to a two-period framework. Delaying outsourcing can be gainful because the fixed cost of outsourcing may fall over time. A social planner would choose a different speed of outsourcing than that achieved under laissez-faire.

This chapter examines the impact of urban development through the government provision of public inputs in a developing economy. When a financing constraint is taken into account, an increase in public inputs may worsen urban unemployment and hence reduce welfare of the economy. Further, the optimal level of public-input provision is larger (smaller) than that under full employment, if there exits a positive (negative) employment effect. The theoretical results are confirmed by numerical simulations.

The collection of essays in this volume provides fairly comprehensive analyses of contemporary theoretical and policy issues in international trade. As technological revolution eliminates communications costs and the countries gear towards more open trade regimes through negotiations at the WTO, the world effectively gets smaller. The evolution of research in trade theory and policy has closely followed the trends in global economy. Issues such as how trade affects distribution of income across and within nations, generates resources for growth, leads to bilateral and multilateral cooperation and conflicts, and many others have been picked up and analyzed systematically in various chapters of this volume. Before we go into the details of the relevant sections and constituent chapters, it is worthwhile to emphasize two special features of this volume.

Purpose – This chapter shows that in the presence of tourism, the traditional policy prescription, free trade in goods and the standard Pigouvian tax on pollution, is not optimal for a small open economy.

Methodology/approach – The general-equilibrium analysis is employed to study environmental regulations for a small open economy with tourism.

Findings – Foreign tourists consume mainly local non-traded goods in the tourist-receiving economy. Inbound tourism converts formally non-traded goods into tradables, generating a tourism terms-of-trade effect. Owing to this favourable effect, positive tariffs and stricter pollution taxes can actually improve welfare of domestic residents. The optimal rates of tariffs and pollution taxes are derived and explained for the economy with tourism. These positive rates are confirmed by simulations.

Originality/value of chapter – The presence of tourism can alter the welfare implications of the traditional trade policy.

Most models attempting to give an account of trade-induced symmetric increase in wage inequality have abandoned the factor price equalization (FPE) framework. The present chapter retains the FPE framework and identifies a plausible route through which trade might increase wage inequality in all trading countries. A two-sector model with one constant returns sector producing basic goods and another increasing returns to scale sector producing fancy goods is developed. A quasi-linear utility function is used to capture the divide between basic and fancy goods. There are two types of productive factors, skilled and unskilled labour, and they differ with respect to their occupational options. Skilled labour can work both in the skill using fancy goods sector and in the unskilled labour using basic good producing sector, whereas unskilled labour is tied down to unskilled job. The model holds possibilities of multiple equilibria and under reasonable parameterization skill premium increases in all countries following trade.
