Two or more variables are said to be cointegrated when they move closely togather over time, after proper scaling. Cointegration was taken to be the statistical expression of the notion of equilibrium in economics. But is it still possible to talk of cointegration when "disequilibrium" economics...

The paper shows how the differing incidence of specific and ad valorem taxation in imperfectly competitive markest can be exploited to control international oligopoly. If countries act cooperatively, the tax instruments used in combination achieve the same outcome, either the first-best or the...

This paper formulates a new theory of financial intermediation and explains the general structure of credit markets. Borrowers without established credit histories have incentives to repudiate their debt obligations, and are therefore unable to issue debt directly. Banks exist in order to...

The appropriate treatment of imports is an important issue in the design and administration of domestic environmental taxes. With the aim of ensuring that foreign exporters do not attain a competitive advantage, border tax adjustments for domestic environmental taxes are used to neutralise this...

This paper investigates the stabilization bias that arises in a model of monetary and fiscal policy stabilization of the economy, when assuming that the monetary authority put higher weight on inflation stabilization than society. We demonstrate that inflation-conservatism unambiguously leads to...

The paper proposes an alternative general equilibrium formulation of financial asset economies with transactions costs. Transaction costs emerge endogenously at equilibrium and reflect agents decisions of intermediating financial activities at the expense of providing labor services. An...

This paper proposes simple Hausman-type tests to check for bias in the log-periodogram regression of a time series believed to be long memory. The statistics are asymptotically standard normal on the null hypothesis that no bias is present, and the tests are consistent.

In numerous auction settings potential bidders incur costs to enter the auction. Such costs may potentially influence bidder’s behavior subsequently. In this paper we experimentally study the effect of entry costs on bidding and entry behavior, through a complete information common value...

This paper considers the impact of ambiguity in strategic situations. It extends the earlier literature by allowing for optimistic responses to ambiguity. Ambiguity is modelled by CEU preferences. We study comparative statics of changes in ambiguity-attitude in games with strategic complements...

This paper surveys the extensive recent literature on the problems of deciding what is meant by an I(0) process, and then deciding how to test for the property. A formidable difficulty exists in the construction of consistent and asymptotically correctly sized tests for the I(0) hypothesis, and...
