This paper develops a set of three models to study the optimal tax-subsidy regime in an economy characterised by two deviations from the perfect competition model – negative externality from pollution by the "dirty" industry, and increasing returns in the "clean" industry. Its main conclusions...

In this note, we introduce increasing returns to Bovenberg and Mooij's (1994) model as generalised in Fullerton (1997) and use an example to show that (1) even with a distortionary labor tax, the optimal environmental levy is greater than the Pigouvian rate; (2) the difference between tax on the...

The Chinese government has been active in trying to cool the alleged bubbles in its housing markets, especially in urban areas. This paper argues that the high housing prices are at least partly caused by some real factors, including the policy of restricting land uses, in particular the...

This paper develops a general equilibrium 3-good Ricardian model that extends Professor Samuelson's example on the impact of productivity progress published in JEP (summer 2004). Our model highlights Professor Samuelson's insight that productivity progress can change the pattern of trade which...

This paper develops a model to study the effects of foreign aid on the creation and distribution of wealth in the recipient country. It considers three types of foreign aid: permanent grants to all individuals, temporary grants to uneducated workers, and foreign aid in the form of low interest...

This paper develops a general equilibrium 2x2 Ricardian model that demonstrates the possibility of immiserizing growth as a result of a productivity improvement in a country's export industry. The model also shows that immiserizing growth can be avoided by improving the productivity of the...

This paper develops a general equilibrium Ricardian model with transaction costs to investigate the determinants of the firm's sourcing decision. It derives conditions under which different sourcing choices and corresponding trade patterns occur in general equilibrium. These conditions suggest...

This paper develops two models to study the impact of outsourcing on wage inequality between skilled and unskilled labor in the developed country and the developing country. The first model assumes symmetric production technologies in both countries, and predicts that outsourcing will increase...

This paper investigates how the trade-off between organization costs, transaction costs and economies of specialization may affect the way public goods are provided. In doing so, it considers two ways of providing a public good. One is collective provision where users organize themselves to...

This paper investigates how monetary shocks are transmitted internationally. It shows that where a national currency is used as an international medium of exchange, the international money is non-neutral. In particular, an increase in the supply of international money leads to a transfer of real...
