The aggregation problem is a well-known difficulty in macroeconometric modelling. It is frequently assumed in these models that the behaviour of economic agents is uniform. Thus the behaviour of a single agent characterizes the aggregate behaviour of the agents (representative agent). However,...

Since the early seventies an increasing attention has been paid to the impact environmental polict nmight have on foreign trade. One of the most important issues is whether countries with relatively strict environmental regulations tend to experience a deterioration of international...

Since the early seventies an increasing attention has been paid to the impact environmental policy has on foreign trade. One of the most important issues is whether countries with relatively strict environmental regulat ions tend to experience a deterioration of international competitiveness and...

The gravity model has long been used for modelling and predicting trade flows. This paper generalises the gravity model allowing for proper representation of local and target country effects and also the business cycle. The new approach is based on a panel data framework (instead of a simple...

The paper presents a monetary model of endogenous growth and specifies an econometric model consistent with it. The economic model suggests a negative inflation-growth effect, and one that is stronger at lower levels of inflation. Empirical evaluation of the model is based on a large panel of...

Transition from economic theory to a testable form of model invariably involves the use of certain "simplifying assumptions." If, however, these are not valid, misspecified models result. This article considers estimation of the dynamic linear panel data model, which often forms the basis of...

The paper introduces for the most frequently used three- dimensional panel data sets several random effects model specifications. It derives appropriate estimation methods for the balanced and unbalanced cases and deals with some extensions as well. An application is also presented where the...

Az utóbbi hónapokban számos írás jelent meg a Közgazdasági Szemle hasábjain, amelyek a magyarországi közgazdasági oktatás és kutatás különböző jellemzőit vették górcső alá. Írásunkkal ehhez a párbeszédhez szeretnénk hozzájárulni. Áttekintjük, hogy szerintünk...
