Sign restrictions on the responses generated by structural vector autoregressive models have been proposed as an alternative approach to the use of exclusion restrictions on the impact multiplier matrix. In recent years such models have been increasingly used to identify demand and supply shocks...

We develop a structural model of the global market for crude oil that for the first time explicitly allows for shocks to the speculative demand for oil as well as shocks to the flow demand and flow supply. The forward-looking element of the real price of oil is identified with the help of data...

The origins of stagflation and the possibility of its recurrence continue to be an important concern among policymakers and in the popular press. It is common to associate the origins of the Great Stagflation of the 1970s with the two major oil price increases of 1973/74 and 1979/80. This paper...

Although there is much interest in the future retail price of gasoline among consumers, industry analysts, and policymakers, it is widely believed that changes in the price of gasoline are essentially unforecastable given publicly available information. We explore a range of new forecasting...

Business services firms are increasingly under pressure from foreign competition. We develop an oligopolistic competition model that studies the effect of trade liberalization on exit and sectoral restructuring in the business services sector. We assume that firms are heterogeneous in their...

This paper examines the rationale for multilateral agreements to limit investment subsidies. The welfare ranking of symmetric multilateral subsidy games is shown to depend on whether or not investment levels are "friendly", raising rival profits in total, and/or strategic complements, raising...

This paper considers the incentives of oligopolistic firms to diversify into technologically related markets when there are diseconomies of scope. There is a rent-extraction incentive for firms to adopt flexible technologies, which enable them to enter technologically related markets, thereby...

This Paper provides an empirical examination of third-degree price discrimination in the Swedish newspaper industry. The results show that price discrimination is more prevalent in competitive markets and among newspapers with low market shares. This supports predictions from recent theoretical...

Motivated by discussions in the World Trade Organization (WTO) on multilateral disciplines with respect to competition law, we develop a two-country model that explores the incentives of a less-developed country (LDC) to offer increased market access (via a tariff reduction) in exchange for a...

We develop a model in which two regional governments compete for a mobile oligopolistic firm by publicly providing local inputs. The central mechanism of our model is the interaction of an agglomeration advantage (partial non-rivalness of the local input) and an agglomeration disadvantage (fixed...
