China has witnessed rapid increases in the skill premium over the last few decades. In this paper, we study the short-run effect of capital goods imports on skill premium in China. The surge in capital goods imports, which embody advanced technology, can explain the rising demand for skills in...

Seminal theories of the firm posit that firm ownership is allocated to minimize contractual inefficiencies. Yet, it remains unclear how much the optimal ownership choice affects firm performance in practice. This paper provides a first quantification of the gains from optimal ownership within...

Using disaggregated US household expenditure data, we study the distributional consequences of the US-China trade war. We estimate a highly flexible demand system to compute household-specific price indexes. The increases in US tariffs on Chinese products between 2018 and 2019 led to an average...

This paper reviews some puzzling economic aspects of globalisation and argues that they cannot be satisfactorily addressed in perfectly or monopolistically competitive models. Drawing on recent work, a model of oligopoly in general equilibrium is sketched. The model ensures theoretical...

I review previous approaches to modelling oligopoly in general equilibrium, and propose a new view which in principle overcomes their deficiencies: modelling firms as large in their own market but small in the economy as a whole. Implementing this approach requires a tractable specification of...

I explore the interactions between comparative, competitive and absolute advantage in a two-country model of oligopoly in general equilibrium. Comparative advantage always determines the direction of trade, but both competitive and absolute advantage affect resource allocation, trade patterns...

Following a brief historical introduction and a discussion of different types of commercial policy, this paper reviews the arguments for and against trade protection. In the bench-mark case of a competitive, small, open economy, free trade maximizes aggregate national welfare, although some...

We present a new model of multi-product firms (MPFs) and flexible manufacturing and explore its implications in partial and general equilibrium. International trade integration affects the scale and scope of MPFs through a competition effect and a demand effect. We demonstrate how MPFs adjust in...

This paper extends the theory of multinational corporations, identifying three distinct influences of internal trade liberalisation by a group of countries on the level and pattern of inward foreign direct investment (FDI). First, the tariff-jumping motive encourages plant consolidation. Second,...

This paper reviews alternative approaches to measuring an economy´s cost competitiveness and proposes some new measures derived from the economic theory of index numbers. The indices provide a theoretical benchmark for estimated real effective exchange rates, but differ from standard measures...
